Application of Rofix roof in buildings
Today, due to population growth and urban development, the issue of safety in construction projects, reduction of construction costs and speed and implementation of work is of particular importance. Due to the length of traditional construction projects and their high cost, construction engineers and architects have designed a type of roof called Rofix that has been used due to its high safety and light weight. The roof of Rofix is made of molds called Rofix, which acts as a more concrete holder and does not play a structural role.
Rofix roof is a type of composite roof with a durable formwork and is a kind of concrete reinforced concrete slab. This roof consists of a kind of metal mesh plate in which longitudinal profiles are installed in parallel at certain distances. The grid has seven V-shaped studs and 7,000 grids per square meter.
With the use of Rufix mesh, it is possible to run and concret all floors at the same time and there is no need for piles and jacks. Roofix roofs are lighter than concrete roofs such as beams and blocks, and do not place additional load on the structure, in fact reducing the dead weight of the building by about 40% because the consumption of steel materials in the skeleton of this type of roof compared to other roofs It is less.
Rufix roof execution
Initially, rofix molds are installed on the side beams so that the direction of the profiles is perpendicular to the side beams. To facilitate the implementation of this type of roof, studs are used as cutters. At the location of the studs, the molds are drilled and the studs are passed through them so that the entire mold is in full contact with the upper wing of the side beams. Then the rebar network is installed on the Rofix without the need for a spacer and the cutters are welded on the beams. Cutters are installed on the side beams and transfer the horizontal force from the concrete cover of the roof to the steel beams. They prevent the concrete cover from separating from the beam. In the last stage, concreting operations are performed.
The advantages of using Rufix mesh metal molds include the following:
Storing Rufix molds does not require much space, and with just one truck, large amounts of molds can be transported and stored in a warehouse or building workshop.
When these molds are placed on the beams of the building, a kind of safe network is created that prevents people and objects from falling.
Rufix does not require expertise and can be performed by semi-skilled workers.
Loading, storing and using Rufix molds, unlike other concrete molds, does not cause any damage.
Rufix metal molds have a high formability, which makes it easy to mold and execute complex molds.
In the implementation of Roofix roof, less accessories are needed, including tools, welding machine, lift and 2 more than other roofs.
The speed of roof molding with Rofix molds is very high.
In most common roofing methods, the next roof can only be applied if the lower roof is retracted, but with Rofix, all roofs can be run simultaneously.
Blocked air inside the roof is considered as a kind of sound and heat insulation.
If the concrete is compacted and it is properly connected to the Rofix networks, the combination of Rofix and concrete plays an effective role in removing or reducing the reinforcement.
Installing Rofix nets on floors does not require lifting or carrying cranes.
The roof of the Rofix has a high level of safety against natural disasters such as earthquakes.
