    Meet the world’s most famous architects

    Probably one of the earliest childhood aspirations to become an architect or an architect who kills his first plan is to design his own home first. Many foreign architects are registered in the world of architecture who have designed their own homes, including Frank Lloyd Wright, Walter Gropius and Philip Johnson.
    The best and most famous buildings in the world are already well-documented in the minds of their architects, with a clever choice of architecture, a clever choice of place to build a home and a smarter choice of materials to create a lasting artwork. That’s why we discover even more interesting things when we put together the history of a building and its main goals. The monument built by some of these architects and their names is known for their iconic work and influence, while other architects have survived because of the innovative style that has transformed the world.
    Famous buildings built by the most renowned foreign architects besides impressing many architects and designers, their stunning beauty is even more appealing to ordinary people and can inspire everyone, even those with little creativity.
    Famous foreign architect design captures specific moments of time with detailed detail that is very similar to the photo and can also provide viewers with information about the time of construction. But unlike photographs, physical structures continue to evolve and live in different eras, and after hundreds or even thousands of years after being built, they can become a central and functional part of the lives of countless people.

    Frank Lloyd Wright
    We usually do not know the names of famous foreign architects as well as other famous artists such as painters. However, their work will affect us in the long run. Throughout our lives, these buildings have been our home and workplace as home for us and as a refuge for us, an artistic architecture that is fundamentally present in all of us. Even if we haven’t walked into any of the buildings designed by renowned foreign architects, in many cases we have been affected by its structure.
    Frank Lloyd Wright was one of the foremost pioneers of American architecture, interior designer, author, and teacher, who designed more than 1,000 structures and completed 532 of them.

    He built the Frank Lloyd Wright home and studio in Oak Park, Illinois, where he and his wife and six children lived.
    Frank Lloyd Wright believed that the design of structures that are in harmony with humanity and its environment is a philosophy he called organic architecture.
    In 1889, when he was just 22, Frank Lloyd Wright received a loan from his employer Louis Sullivan for $ 5,000 to build his home and studio. Later when Frank Lloyd Wright started his architecture he added the studio to the design of the building.
    The house has been preserved as a national and historical landmark since 1909 and continues to exist.
    Frank Lloyd Wright describes architecture as “the art of motherhood”: “We do not have the spirit of our civilization without an architectural style of our own.”
    Frank Lloyd Wright argues that buildings are, in fact, a practical necessity and an artistic expression of a culture. Architects not only build civilization but also make it more beautiful.
    In addition to the homes he built for himself, Frank Lloyd Wright has designed many offices, churches, schools, towers, hotels, museums and other structures.
    He also designed most of the interior elements of buildings such as furniture and other accessories. Frank Lloyd Wright has written 20 books and articles on architecture and is known as a popular lecturer in the United States and Europe.
    He was born on June 8, 1867 and died on April 9, 1959.

    Walter Gropius
    Walter Adolf George Gropius is a German architect whose names are known alongside famous architects such as Alvarez Alvert, Ludwig Mies van der Droe, Le Corbusier and Frank Lloyd Wright as the most renowned leading foreign architects in modernist architecture.

    Walter Gropius is also recognized as one of the leading architects of international style.
    Walter Gropius was born on May 18, 1883 and died on July 5, 1969, and a neighborhood in Berlin is named after Gropiusstadt.
    In the early 1990s, a collection of all of Walter Gropius’s German architectural activities was published in a book entitled The Archive of Walter Gropius.
    The Gropius House was the first project of Walter Gropius, the founder of the Bauhaus School in the United States.
    Walter Gropius built this home, just an hour’s drive from Harvard in 1938 for his family. Although maintained like other neighboring houses and endorsed by the traditional materials used, it does not depart from the modernist architectural style with its bright white exterior, stripped windows and shattered glass.

    It has also been considered by the US government as a landmark in the country.
    In 1980, Gropius’s wife donated Gropius’s home in Lincoln to the history of New England.
    Walter Gropius’s house was added to the National Historic Places Journal in 1988 as one of the historic sites and is now being visited by Uncle

    Johnson is renowned for his modern architectural works such as the glass house in New Canaan and Connecticut, and especially his postmodern architecture such as 190 South La Salle Street in Chicago and 550 Madison Street designed by AT&T.
    Philip Johnson received the Gold Medal of the American Institute of Architects in 1978 and the first Pritzker Architectural Award in 1979.
    American architect Philip Johnson designed his famous glass house for his residence.
    Completed in 1949, this single-storey house is made of glass and is positioned between two horizontal surfaces and a light steel structure.
    This home is a symbol of international style and a national historic landmark of the United States of America.
    Although it is widely believed that the house was inspired by Mies van der Rohe’s Farnsworth house, Mieswend himself stated that this was not the case and said that the time of visiting Philip Johnson’s glass house had been affected.
    In 1930, Philip Johnson joined the Architecture Department of the Museum of Modern Art in New York.
    He regularly met with other foreign architects, such as Gropius and Leverbusier, and for the first time in the US Congress negotiated with Miss Van Derweh.

    In 1932, Philip Johnson in collaboration with Hitchcock, Alfred Haber and Jr. held the first exhibition of modern architecture at the Museum of Modern Art.
    Since 1922 he has played an important role in introducing modern architecture to the American people.
    Philip Johnson passed away on January 25, 2005.

    Meet the world's most famous architects

    Oscar Niemeyer
    The Casa das Canoas house is one of the world’s most famous structures built in 1951 by Oscar Niemeyer, one of Brazil’s most famous foreign architects.
    The name of Oscar Naimier, along with the renowned architects who have contributed to the development of modern architecture, is one of the main figures of modern architecture.

    Naimir was known for designing residential buildings for Brazilians in a city planned to become the Brazilian capital in 1960, and also for collaborating with other foreign architects at the UN headquarters in New York.
    His discovery of the beauty of reinforced concrete in the late 20th and early 21st centuries was very impressive.
    Naimir has both been endorsed and criticized for the sculpture.
    He said his architecture has been heavily influenced by Le Corbusier’s architecture, although he said in an interview that this did not change his architectural direction.
    Niemeyer was famous for using abstract and curved forms.
    The design of the Cassadas Canus home depicts the combination of modernity and the architect’s own style. This feature is a unique integration between minimalist and fundamentalist architecture.
    Situated on a hill slope overlooking the bay and surrounded by it.
    It is also combined with the green of nature. Cassadas Canos is a showcase of the evolution of reinforced concrete (or reinforced concrete) that has been widely used as a flexible building material.

    Alvar Aalto
    Hugo Alvare Henrik Alto is a Finnish architect and designer whose work includes architecture, furniture, textiles and dishes as well as sculpture and painting.

    Although Alto never considered himself an artist, you can see his collection of paintings and sculptures entitled “Tree Branches with Architectural Trunk”.
    His career was from 1920 to 1970. He first followed the Nordic ancient style and then moved on to the style of international modernity that was more rational in the 1930s and eventually adopted a more modern style in the 1340s.
    In 1934, Finnish architect Alvar Alto and his architect Aino Alto designed their residence and studio in a neighborhood called Munkkiniemi in the Finnish capital.
    The appearance of the house is distinguished by its two major parts. Most of it is painted white and most of it is covered with brick while being merged to form the lower part of the house.
    Alto’s cozy home and its impressive design are thought to have been taken from Mairea Villa, a guesthouse in Normako, Finland.

    This artwork by Alvar Henrique Alto is renowned as a world-class work of art. The interior design of the house and the design of the furniture, lamps and utensils were also done by Alto himself and his wife.
    He used a modern Scandinavian design to design his furniture. The Alvaro Alto Museum, designed by Alto himself, is located in the city of Yuquila.
    Frank Gehry
    Born in Canada in 1929, Frank Gehry immigrated to the United States as a teenager, and his name is recorded alongside many other architects in postmodern and creative architecture.

    Like the lucrative and lucrative tendencies of internationalism, the style of irregular shapes explores radical and meaningful shapes.
    He was highly regarded in the 1960s and 1970s and suddenly became popular when he presented his corrugated cardboard furniture design. By the 1990s, he neutralized his style and gained popularity by designing seemingly organic, undulating and free-flowing structures.
    In the 1970s, Frank Gray bought a house in Santa Monica to move in with his wife. However, if you know Frank Gray, you can never believe that he is just living at home and that is true.
    In 1978, Gary transformed it into a luxurious home with a symbol of structural thinking. The main house has its colonial style on the left, but an unusual new structure, including glass planes, walkways, discrete columns and exotic angles, covers the other three sides of the house.
    The Guggenheim Museum in Bilbao, Spain, inaugurated in 1997 and designed to resemble ships and living things, was designed by Frank Gray.
    He also designed the Walt Disney Concert Hall in Los Angeles and California, which opened in 2003.

    Frank Gary is known not only for his unique structure but for his superior acoustics among foreign architects.

    Conclusion:
    There are many architects around the world who have been named after many foreign architects because of the unique design of their homes.
    Frank Lloyd Wright and Walter Gropius and Philip Johnson and Oscar Naimier and Alvar Alto and Frank Gray are exterior architects whose homes have been highly regarded for their special design. The Wright House in Illinois Park, for example, has already been preserved as a national and historical landmark. The Gropius House in Lincoln, Massachusetts, has been used as a landmark for the United States by utilizing modernist architecture. The Johnson Glass House in New Conan, the Cassadas Canus House in Baradigio Rio de Janeiro, the Alto House in Mankinimi Helsinki, and the Gary Residence in Santa Monica, California, are other well-known homes whose designers are known for their unique design.

  • Understanding the stages of building from zero to one hundred

    Understanding the stages of building from zero to one hundred

    We all live in safe, comfortable homes, and usually when we walk into a building when the building is fully built, but many of us may not know how to build a home. For many of us, there may be a question as to what are the stages of construction and what to do at each stage. Many people who own a land, never having thought of building a building on their land because of the constant fear of getting into the construction phase, are always afraid. In this article, we are going to explain the steps of building from zero to 100.

    Steps of building a building;
    Pushing or pinning is one of the steps of building construction and is an operation to strengthen the building’s veneer. The legs are parts of a building that move the forces of the building to the ground, thereby reducing the vibration intensity and strengthening the building. The foundation operation must first be excavated; excavation is the removal of a large volume of soil, which results in a very large hole at least half a meter deep throughout the earth.
    If the height of the building to be constructed is not too high, low-level excavation is also called superficial excavation. This type of excavation can sometimes be done manually even with a pick and shovel. Deep construction is required for the construction of large buildings and tall towers, which will be done using excavators and drilling machines. Excavation is done to ensure that potential land meetings are held; in this case they are said to be excavated until they reach pristine land.

    In the pouring operation, the primary concrete does not come into contact with the soil directly; instead, a low layer of cement is called “cement except”, and then the foundations are laid on it. This will minimize the chance of corrosion and erosion of the legs. At this point, a map of the building where the foundations and other items are marked on the paper is also executed on the ground.

    Steps of building construction; building reinforcement
    Reinforcement is one of the most important stages of building construction which, if not done properly, threatens the strength of the building. The types of forces applied to concrete can be divided into compressive and tensile forces. The compressive strength of concrete is defined as the resistance that the concrete exhibits to its perpendicular forces. Tensile strength is also related to the resistance in which the forces are reciprocated into the concrete. Concrete has high compressive strength but is very fragile and weak against tensile forces.
    Reinforcement as one of the stages of building construction is precisely for this purpose to increase the tensile strength of concrete. Reinforcing bars are joined by welding or metal fastening to increase the tensile strength of the concrete. In fact, all tensile forces applied to the building are inserted into the bars. For small concrete construction, reinforcements with a diameter of 12 mm or less are used; however, for large concrete structures 13 mm, 16 mm and 20 mm diameters are used.

    Reinforcement is used as one of the stages of construction in a concrete building and is of particular sensitivity, so the error rate should be as low as possible, otherwise it would pose a threat to the safety of the building.

    Understanding the stages of building from zero to one hundred

    Process of building; molding and concrete building
    Molding is another process of building a concrete building that uses wooden or metal pieces to form concrete. In the concrete stage, the concrete is soft before being hardened and may collapse; therefore, the presence of molds ensures that the concrete retains its shape until hardened and with high resistance to cohesion.
    At this point, the molds must be carefully mounted and tightened; otherwise they may open during operation due to pressures and may damage the concrete. In Iran, the use of wooden molds for concrete building concrete is more common; since mold boards may adhere to wet concrete at the time of molding, surface them with special greasy oils to prevent this from happening. Also, greasing the boards will prevent the moisture of the concrete from spreading to the wood and make the concrete firmly firm.
    Molding is also particularly sensitive during the construction process; for example, when lubricating the molds, it is important to ensure that the oil does not spread to the reinforcement; . The molding for the different parts of the building is done in certain ways; these are: columns, foundations, main beams and ceiling and all of them must be molded.

    Construction stages; steel structure of the building
    In this section, we will explain how to install steel structure in non-concrete buildings. It should be noted that all stages of construction in concrete and metal building are the same and the only difference between these two types is in the skeletal stage. In this method, columns, bridges and beams are first constructed and then stairs are placed between the floors. Columns are made before other parts.
    The types of columns in a steel structure are divided into three categories depending on the load on them:
    The first batch is the middle columns centered on the square with the total load applied to them.
    The second batch is the sidebars, which are cut in half.
    The third category is the corner columns, which are accessed a quarter of the time.
    In executing the steel framework, the columns must be carefully welded together, and any pores in the welds can interfere with the overall strength of the skeleton. Metal columns should also be pre-stained with stainless steel. If the stainless steel is not used to cover the columns, it will subsequently oxidize or rust, resulting in corrosion, which destroys their strength.

    Construction stages; vector molding and finishing works
    At this point, the jaws are placed beneath the molds to withstand the forces for a specified period of time until the molds become firm. After executing the steel structure or molding in the concrete building, it is the staircase and the creation of pavilions. Wall and ceiling insulation should then be installed, including acoustic and thermal insulation. The insulation is usually carried out within a short period of time in the construction process, followed by various plumbing and installations.
    After the piping is completed and the pipes are insulated, it is time to place the pottery and the main materials in the walls. Concrete is sprayed on the walls where the work is completed. This is usually done with special machines that push the concrete out. However, in some cases for small buildings this may be done manually. Bleaching is another process of building after concrete spraying, and it can be said that the final work on the walls and ceiling is done at this stage. Finally, exterior design is based on previous designs and installation of accessories such as boilers, cabinets and more.

    Some important points
    It is necessary to explain that prior permission for the construction process must be obtained from the relevant institutions. The building permit is one of the most important basic permits that must be obtained before construction begins; otherwise, the municipality will prevent any construction operations.
    Another point to note is the comparison between the concrete structure and the steel structure; each has advantages and disadvantages. For example, the steel structure is less resistant to fire and heat, but on the other hand it is much faster than the concrete structure and will speed up the construction process faster because the steel structure can be run simultaneously in all parts. Be. The cost of steel used in the steel structure is higher than that of steel in concrete construction; also, since mortgages on construction projects are paid on completion of the construction process, concrete buildings can be repaid after the completion of each floor. Received and financed the construction of the other floors.

    However, in buildings constructed of steel, the relevant loans can only be obtained at the end of the entire construction. Steel structures have longer lifespan than concrete structures and also have decay value, meaning that when steel buildings are demolished, steel skeletons can be sold as second-hand, but there is nothing to demolish concrete buildings. . Given the issues raised, it is not absolutely possible to choose between these two types of structures, but it must be determined depending on the type of building and its type of use.

  • Reinforcement of concrete structures

    Reinforcement of concrete structures

    Reinforcement is one of the principles that has always been considered in the performance of concrete structures and has a great influence on their strength. Reinforcement enhances the tensile strength of the structure and strengthens it against environmental stresses. This method is one of the most basic methods in the creation of modern buildings and makes the structure acceptable in terms of engineering principles. Reinforcement should be fitted with a suitable size rebar to ensure the strength of the structure. In the fitting of the armature, the rods are arranged together in a special order and are connected by metal fastening or cold welding. Reinforcement is performed in the form of curved and locked rods for the construction of columns and foundations of the building and in the form of a few simple rods joined together for roofing. Bending of bars for reinforcement is done by different methods, each of which is suitable for different structures. In general, reinforcement is performed in three regular, nodal and Croatian methods. Cold welding is used in all three methods to hold the bars together because conventional welding reduces the tensile strength of the reinforcement due to the lack of flexibility. Reinforcement has the following advantages:

    The strength of concrete structure is increased by reinforcement against factors such as fire and moisture.
    Reinforced concrete does not require maintenance costs.
    Construction of concrete structures requires less skill than steel structures.
    Reinforcement is one of the most important factors preventing the building from deviating from its primitive state.
    Concrete reinforcement can be shaped into different shapes.
    Reinforced concrete has a high compressive strength compared to other building materials.
    Reinforcement plays an important role in increasing the tensile strength of the structure.
    For the construction of columns, foundations and reinforcement dams, the best option is to increase the structural strength.
    Methods of fastening rebar by wire
    The shape of the bars in the reinforcement plays an important role in the concreting and for the concrete to reach different points. When constructing columns that use large-size rebar, try to allow more space for the reinforcement and molding to reach the concrete. For lower parts of the reinforcement, insulation should be used to prevent soil moisture from reaching the structure and destroying it. Before concreting, the reinforcement must be checked by the engineers as it may be torn as a result of relocation or other wire construction work. Therefore, if the wire is loose or loose the wires should be re-closed. Reinforcing bars are closed in two ways:

    The Crucifixion Method
    In this method, the two bars are placed over each other and the wires are crisscrossed below and above them. The ends of the two ends of the wire are then screwed together using pliers. Finally, the excess wire is bent downwards so that the tip of the wire does not cause any problems.

    Reinforcement of concrete structures

    Closure method
    In this way, when the bars are mounted on each other, the wire is passed underneath the lower bar and closed after passing through the upper bar. This method of closing the rebar is called the Croatian method and is used for roof reinforcement and building foundations.

    Concreting
    Molding and concrete is the last step in reinforcement. The molds chosen for pouring concrete are metallic because they prevent the water from leaving the concrete. Concreting depends on factors such as weather conditions, construction site, desired land condition and concrete location. Ready-mixed concrete is used in bulk casting because it is of the required quality.

    Important tips in reinforcement
    Reinforcing is a very specialized job and should always be monitored carefully. Sometimes fittings provide wake resistance, so supervisory engineers must be supervised before reinforcement for foundation. The construction of concrete structures using reinforcement requires some of the following:

    They are called bamboo transverse bars and their task is to maintain longitudinal reinforcement, so the principles and criteria must be observed when bending.
    The reinforcement shall not be bent below 2 ° C.
    The bent reinforcement should not be opened or closed.
    Bending of the bars is done using a cold mechanical device.
    The bars should be cut using special scissors.
    The distance between the barrels should be twenty centimeters.
    Oil-coated, rusted or contaminated reinforcement should not be used. They must be cleaned before the project can be implemented.
    Environmental conditions must be considered when installing reinforcement.
    Reinforced concrete approved by engineers should not be changed prior to concreting.
    When formatting, the gap between the bars and the mold wall must be observed as failure to observe this distance will result in damage to the foundation.
    Bending of reinforcers by the airbag should be avoided.
    Opening and closing bends should be avoided to reshape them.
    The thickness of the coated concrete shall not be less than the diameter of the reinforcement.
    Reinforcements used for reinforced concrete structures should be prepared on a map basis.
    Coverage thicknesses are not required for floor and ceiling reinforcement that is not subject to transpiration if the monitoring device agrees.
    The distance between parallel bars shall not be less than 1.5 cm from either side.
    More than half of the reinforcement in bending and pressure components should not be patched at one point.
    The distance between each patch to the adjacent patch should be 3 times the diameter of the reinforcement.

  • Safety and Health of Building Materials and Products

    Safety and Health of Building Materials and Products

    Perhaps one of the aspects that is often overlooked or less overlooked in the design of a structure is the choice of materials and construction products. The importance of choosing the right construction products is very important and this plays an important role in the success or failure of a building. Even the use of standard building products has a significant impact on home prices, and each of us has probably heard about the quality of our housing and its price at least once when buying a home or mortgage and renting it.
    In our country, the Ministry of Roads and Urban Development has enacted the technical and engineering aspects of building and national regulations governing the technical and engineering aspects of building, and compliance with these rules is essential for all construction activists.
    Although these regulations are presented in various categories such as the standards defined for each material, its specifications and technical specifications, its adaptability to its construction and its type of packaging and maintenance, we present in this article from Keyword Magazine to the Materials Safety and Health Environmental Some of the building products used in building a building are:
    A few items of construction products
    Generally, for the construction of a structure, the technical specifications of construction products must be standardized and materials that have quality certification must be used.
    Hydraulic Cement
    This type of cement is very sticky and hardens in combination with water or its proximity (also air). Thus, by definition, hydraulic cement is waterproof and does not perish in the face of water.

    Materials safety and environmental considerations of hydraulic cement
    This type of cement contains a small amount of live lime and other alkaline oxides, so it can be harmful to the skin and eyes, and dust in the air can cause respiratory problems. Therefore, cement should not be dispersed in the air.
    When using cement, people need to wear gloves, glasses, masks, and long sleeves to prevent it from impacting different parts of the face and body.

    If the cement comes in contact with damp skin or eyes, it should be washed off with plenty of clean water as soon as possible. In case of prolonged exposure to cement, it is advisable to use dilute vinegar solution to wash the skin after the area has been rinsed.
    Plaster and its products
    Plaster is a building adhesive that is white in color, if pure. If gypsum is cooked at low temperature and in laboratory conditions, gypsum is obtained.
    Material Safety and Environmental Considerations of Building Plaster
    In structures that use building plaster, workers also use shoes, protective boots, gloves, masks and safety clothing. Also, be careful when loading the construction plaster so that the envelopes are not torn and dust is not created.

    Building plaster compatibility with other materials
    Building plaster products, especially in wet areas, should be covered with stainless steel if exposed to steel.
    Building plaster and its products in related areas, such as the northern cities of the country, should not be directly adjacent to concrete or cement products.
    Construction mortars
    Generally, a paste that is created by mixing adhesive and filler is called fresh mortar. This adhesive can be cement paste and the filling material can be like fine aggregates.

    Mortar is used in construction to glue building materials together. Mortar provides the necessary bedding for plastering, plastering and bonding.
    Materials safety and environmental considerations of building mortars
    Since lime mortar is often used in construction, hydrated lime is best used, and due to lime damage to the skin and eyes, it is necessary to consider the safety of materials and individuals and to avoid lime contact with the working skin. Prevent action.

    Safety and Health of Building Materials and Products

    Compatibility
    Lime, due to its composition of ingredients, causes corrosion of metals such as lead, aluminum and zinc. For this reason, it is necessary to coat metal materials with appropriate materials before placing them in calcareous mortar.
    Building stones
    Stones are one of the most commonly used materials in construction. Sometimes the stones are used as blocks and sometimes cut to decorate the floor and floor.

    Natural stone consists of one or more minerals and is a synthetic stone made from a mixture of aggregates, adhesives and additives.
    Materials safety and environmental considerations of masonry stone
    Cutting stones should be done indoors using water.
    The use of stones in buildings should never endanger the health and health of people and the environment. If it is likely that harmful radiation is emitted from the stone, it is necessary to examine and test the stone.
    Stones are compatible with all construction products.
    Ceramic tile
    This product is used for floor and wall covering and decorative items. Ceramic tile is manufactured with different properties and systems and is a combination of different minerals.
    Materials Safety and Environmental Ceramic Tile
    Glazed tiles contain some compounds such as lead oxide and cadmium that are harmful to the environment.
    Warehousing and painting of tiles should include safety helmets, work shoes and boots, and staff should be provided with personal protective equipment.

    Like stone, tiles are no longer incompatible with other building products.
    Bitumen
    Bitumen is a hydrocarbon material that is produced from complex chemical compounds of organic hydrocarbons. It is solid and semi-solid at ambient temperature but flows with increasing temperature. Two important properties of bitumen that make it used in the construction industry are its adhesion and resistance to water penetration.
    Materials safety and environmental considerations bitumen
    The most important safety issue in using bitumen is choosing the right temperature for heating and consuming it. This temperature varies depending on the bitumen.

    Maximum use of 176 degrees Celsius is permissible for pure bitumen. This temperature depends on the concentration of dissolved bitumen. For dilute bitumen, pass 30 to 50 degrees Celsius, and for the thicker bitumen, the limit is between 80 and 115 degrees Celsius.
    Compatibility
    The compatibility of this construction product depends on many factors such as climate, climate and average ambient temperature. Traffic passing through this material also has an effect on its compatibility.

    Thermal insulation
    Thermal insulation is used in construction to reduce heat transfer. Due to the chemical compounds used in thermal insulation and its physical structure, the resistance of thermal insulation varies. In general, the thermal insulation resistance is more than 0.5 m 2 Kelvin and its conductivity is less than 0.065 w m.

    Glass wool, mineral wool, stone wool, slag wool, cellular plastics are some examples of thermal insulation classifications.

    Safety and Health of Building Materials and Products

    Materials safety and environmental considerations Thermal insulation
    Since mineral wool insulators are capable of causing itching and skin sensitivity in individuals, it is necessary to use this type of thermal insulation with gloves.
    Mineral wool, though non-flammable, burns if they are in the middle of paper.
    Wood and its products
    To use wood as a construction product, it must be used as follows:
    Natural, saturated, modified, layered or multi-structural. Wood is used to build skeletons of wooden buildings, door and window frames, fences, flooring and more.
    The important thing about wood safety is that wood should not be used in an environment where there are caries.

    Iron and Iron Products and Welding Materials
    Pure iron cannot be used for building construction. Iron is used in the form of steel, cast iron and a combination of multi-metal and non-metal construction. The definition of welding in the building industry is also the operation of bonding between two metals with the help of electric arc heat.
    Welding properly requires a thorough understanding of the welding materials.
    Iron safety and environmental considerations
    During the forging and cutting of iron, it is essential for workers to wear safety goggles and masks as they are very likely to cause injury to the face and eyes by throwing iron cuts.
    Iron compatibility
    All steel parts need protection against corrosion and rust.
    For cases where steel is more likely to rust, such as sewage and drainage pipes, cast iron is required.
    In wet areas, steel nuts, sheets and nails need to be coated.
    Result
    Using different ideal construction products in designing your next project will affect you in many ways. Therefore, to avoid potential problems in the future, it is best to take the time to examine the details of the different materials and to know their safety-related issues at work.

  • Take the safety of your building seriously to prevent accidents at home

    Take the safety of your building seriously to prevent accidents at home

    Many of the buildings in which we live today lack security and safety; as a result, many people are constantly experiencing insecurity at home. Building safety has always been an important part of construction, and using the best equipment and the highest level of knowledge in the field can save the lives of thousands and even millions. Incidents that can endanger the safety of the building and our family members are not the only unexpected events such as earthquakes, floods, hurricanes, etc.; in fact, failure to comply with building safety principles can endanger the lives of any occupants .
    Now you might be asked what are the key things to keep safe at home? Is there a way to increase the safety of your building and your living space? What are the safety factors in a building? And many similar questions. In this article we seek to answer the above questions.
    Building Safety Assessment

    To answer these questions, we first need to evaluate the safety of the building. These evaluations are based on a variety of factors, such as structural strength assessment, fire protection system evaluation, systems such as elevators, automatic doors, stairs and so on.

    Currently, there is a set of standards that can help to some extent ensure building safety. In fact, the safety of buildings is divided into three categories: high risk, low risk and intermediate risk. The assessment for building safety is based on international standards and therefore high-risk buildings should be inspected annually, at least once every 10 years, and once every 3 years.
    Building safety assessment can be done by the fire department. In addition, experts and engineers can be consulted to find out the strength of the building and its safety principles. One of the issues to consider for building safety against unexpected events is, for example, earthquakes, the building’s distance from faults, and for storms and floods, its distance from sea level.

    Earthquake safety

    Earthquake is one of the unexpected events that threaten our country every day and endanger millions of lives. As a result, maintaining the safety and soundness of buildings is of great importance. Construction techniques can have a huge impact on earthquake mortality and mortality.

    The most dangerous structures from earthquake point of view are buildings made of brick block or cordless block. This type of construction has walls made of brick overlaid with mortar. In these structures, the roof weight is transferred directly to the base through the walls. When this type of construction is affected by the force of the earthquake, walls and ceilings will fall.

    Take the safety of your building seriously to prevent accidents at home

    Fire prevention

    Another incident that could threaten the safety of our building and our living space is the fire. In order to prevent a fire in the building, it is necessary to make a point.
    Power problem:
    One of the building safety principles is the power cables. Many older buildings have damaged or damaged electrical or wiring systems. Get expert help with checking and building electrical systems.
    Do not use a power outlet to connect multiple home appliances (by a tee). For example, the refrigerator should be connected directly to a separate outlet. Problems with the operation of a home appliance can indicate a serious problem with the building’s electrical system.

    Kitchen Safety Tips:
    Do not place the pot or pan on light gas when you are about to leave the house. Microwaves, like gas, have a fire hazard and should not be turned on without being at home. Place the lid on the stove so that the child does not have access. If the handles are plastic, make sure it does not fit on the adjacent flame.
    Installation of fire alarm system:
    One of the simplest, yet safest, measures to be taken to increase building safety is to install a fire alarm in each room and hallway. The system is sensitive to smoke and alerts quickly when a fire occurs. This system should be replaced every 10 years, remember the date of replacement when installing the system.

    Fire extinguisher:
    Fire extinguisher capsules can be considered as one of the most important principles in building safety and preventing major fires. Make a fire extinguisher and place it where all family members are aware. Also teach your children how to use this capsule. If you want to put the capsule in your kitchen, it is best to be about a meter away from the stove. It is recommended to have at least one fire extinguisher in your home, work and personal car.

    Conclusion
    The safety of a building can substantially provide us with peace of mind. Therefore, compliance with building safety principles must first be closely observed and monitored by contractors and supervisors. But the role of the individual in the home environment is also very important and can be a source of health for the family.

    Types of formatting in foundation implementation

    The foundation or foundation of a building is one of the essential components of any structure and its task is to withstand the pressure caused by the columns and transfer this force to the ground. According to the type of structure and the location where it is to be carried out, the construction is performed under different conditions to provide the strength and strength of the structure. The foundation is the first stage of construction and the standards required for its implementation must be met. In previous posts, the builder introduced the types of building foundations, and now we are going to explain the foundation formatting for you. Stay with us.

    Foundation formatting
    In molding foundations, wood, metal, and brick molds are used, each with its own unique characteristics. In the formatting system, different panels are used for formatting, which can be created in different shapes depending on the type of structure and the execution plan. The foundation for the building after excavation needs to be axed and the mold positioned on the ground to allow the foundation to be laid. Among the points to consider in formatting a foundation are the following:

    The molds need to be firmly fixed and secured.
    Consideration of the dimensions of the foundation is very important in choosing the mold.
    The molds should be designed and manufactured so that they can be easily installed or opened quickly and easily. This will save you considerable time and money.
    Appropriate sealing should be done to prevent the loss of concrete sap.
    Mold oil should be used to improve the quality of concrete surface and mold strength.
    Molds must be of high durability so that they can withstand the pressure and loads without breaking or squeezing the concrete.
    When considering whether a foundation is a facade, attention must be paid to determining the quality of building materials and formatting.
    The molding and mounting of the molds must be such that the dimensions, shape and appearance of the concrete are achieved.
    Placing the foundation and adhering to the cover of reinforcement are also important points in forming a foundation.
    Templates must be selected in such a way that they can be transported and accommodated with available facilities.
    The templates used to lay the foundation include:

    Metal molding
    Metal molds have better strength and surface roughness than wood and brick molds. Nowadays, these types of molds are among the most common molds used in building construction because they can be easily transported and used in any type of operating system. The advantages of metal molding include high durability, ease of connection, high speed of operation, reusability and high productivity. Metal projects are the best option in projects where the dimensions and dimensions are low but the workload is high. Although the initial price of these molds is expensive, they are long lasting and can be used for many years. In order to prevent adverse weather effects on these molds, they should be even insulated.

    Types of formatting in foundation implementation

    Metal Mold Components
    What are known as metal molding components are various components for concrete molding. These components can be different in different projects. Examples of metallic mold components include cast iron bolt, case washer, ball strap, coarse-grained metal longitudinal clamp, double screw jack and so on.

    Brick molding
    This type of mold is used around the foundation, and after the concrete has been retained, remains in the desired location and is considered a permanent mold. To prevent the concrete from being squeezed by brick, a layer of nylon sheet before the concrete is required. Finish install on the wall, otherwise the bricks should be thoroughly sprayed. However, when spraying, the fact that water should not accumulate in molds should be kept in mind.

    In this type of formatting, the boundaries of the structural axes and molds must be specified by the surveyor. To avoid the slightest error in performing this type of formatting, it is advisable to nail the corners of the axes and templates and paint the border of the molds after it has been marked with a string. In addition, the ground surface must have a uniform alignment, which is done by mapping. When brick molding, a thin layer of cement must be applied to the inner wall of the mold, but plastic can also be used if not. The back of the brick mold can be filled with dirt.

    Wooden Molding
    The wooden mold, as its name implies, is made of wood. Molds are made enough to be transported to the desired location. Concrete molding in these molds requires sufficient care to prevent damage to their edges. Wooden molds are lighter in weight than metal molds, but their resistance to moisture is not high. The benefits of this type of mold include ease of execution and connections, low thermal coefficient and light weight. The only disadvantage of not using a wooden mold more than 3 times.

    Concrete Molding
    What should be taken into account in concrete molding is the strength of the molds and their proper bracing. To increase the durability of the scaffold, the use of longitudinal and transverse straps is required. Concrete molding should be designed to prevent the concrete from getting out of them. Molds must be cool to run concrete. If the formatting is hot, it reduces the quality of the concrete and changes its color. This causes the concrete to lose its proper shape.

    What is a Modular Mold?
    Another name for the concrete mold is the modular mold. This type of molding is manufactured in various sizes and is used in the molding of concrete structures.

    Concrete mold fittings
    Parts are needed to connect the concrete mold and create a suitable concrete structure. Components needed to do this are clamps, medium and long clamps, tube-to-tube clamps, ballet, cane ball, medium clamp, cast iron bracket and so on.

    Types of formatting in foundation implementation

    Ubot template
    The Ubot mold is used to create a hole in the concrete slab. Doing so can remove inefficient concrete and help lighten the slab. There are generally four models of Ubot templates, including single Ubot templates, Double Ubot templates, Inflatable UI templates, and Polystyrene Ubot templates.

    Price of Ubot template
    Buying a Ubot template is very affordable. Because this template is not particularly complex in structure. What is impressive about the price of the mold on the ceiling is the height of the mold. Other factors affecting the price of the Ubot template are project metrics.
    Waffle template
    One of the modern structures that can be used in construction is the waffle mold. The Waffle mold is an example of ceiling molds. These lattice-like molds cover a large part of the ceiling. Using these molds will not harm the construction equipment. These molds are cube-shaped and hollow. The benefits of using these molds include earthquake safety, fire resistance, sound and heat insulation, removal of blocks and joists, and reduced costs for fitting and molding. There are also disadvantages to using these templates. For example, since waffles are lightweight, it is not possible to use them in areas with high winds. It also needs proper soil to fill its molds.

    Run the waffle template
    Waffle molding is simple and requires no special equipment. In general, the steps to implement a waffle roof include roof cushioning, waffle molding, roof reinforcement, concrete casting and molding.

    Buy Waffle Molds and Price Waffle Mold Molds
    The price of waffle mold depends on several factors including the dimensions of the mold and its types. When purchasing waffle molds, you must first specify the types you want. Waffle molds are available in a variety of one-way and two-way molds, each priced differently.

    Slider format
    Slider Mold or Slider Mold is an example of formatting methods in which the mold moves forward or upwards at regular intervals. In this molding method, the surface of the sliding mold is in contact with the concrete and is not detached and, as the name implies, slides over the concrete. Types of formatting in foundation implementation

    Metal mold for concrete
    An example is the best form of molding in a concrete metal molding foundation. Because this type of formatting is more robust than other types. Other uses of metallic concrete are projects where the depth of foundation is very high.

    Column template
    In general, it can be said that the column is an important part of a structure and therefore its accuracy is very important, especially in the event of an earthquake. Column molds consist of two main components. These two components include mold walls or metal panels and coils or shackles.

    Molding board
    The use of molding boards is particularly important in the construction of concrete buildings. Since the concrete is smooth before being hardened, it needs mold to form. The use of molding boards was more common in the past and today the use of metal molding has somewhat reduced their use. The advantage of using molding boards is compared to metal molding. For example, using a molding board is less expensive and cost effective than a metal molding. Since these molds are lighter in weight, they have a higher velocity for the mold. Note to use quality formwork boards. Because if the boards are not of a good quality, they cannot withstand the weight of the concrete and this will cause the deformation of the concrete. Molding boards are used in molding foundations, column molding, main beam molding and ceiling molding.

    Molding equipment
    Required formatting equipment can include cane bolt, double-ended bolt, mid-bolt, double tube washer, cassette washer, long clamp, medium clamp, cast iron seal, metal seal, cast iron bolt, ceiling jack Ceiling, threaded jack jack, adjustable ceiling jack base and adjustable ceiling jack.

    Architectural concrete molding
    Since contemporary architecture requires different forms of texture and surface finish, the use of such material is particularly important. Therefore, the use of concrete can meet this need. In this regard, a concept is defined as architectural concrete. Architectural concrete is visible on the interior and exterior surfaces of the structure and therefore its appearance is important. One of the important processes in concrete structures is the use of formwork. Complexity of structures increases the need for special molds. This special method is designed for architectural concrete molding. What is important in the design of architectural concrete molding is the use of suitable material for its construction.

    Important points in the foundation vector
    When formatting, a number of things should be considered, including:

    If the molding is removed before the maintenance period is completed, concrete care must be taken after molding.
    The molding should be done step by step and should not be hit. Sudden loads and impacts should not be introduced to prevent concrete damage.
    The mold should be removed when the concrete is able to withstand the forces and not deform.
    Bearing molds and supports should not be removed until the concrete components are sufficient to withstand their loads and loads.
