Trussing system installation - highlights

In the multi-storey buildings of the out -of- date design, the balconies of the last floor remain open. They are unprotected and there is no next balcony above them. Installation of a roof on the balcony of the last floor is simply necessary. The snow accumulating during winter during thaws becomes ice, which leads to an increase in the load and its possible collapse. Even more dangerous is the period when snow begins to thaw off the common house roof. At this moment, it is dangerous to live on such a balcony. Therefore, mounting the rafters is a must.

Project development

You can only do a visor, and you can set the goal of glazing the balcony. The roof must be solid and reliable. When you use it, you often have to take into account the architectural style of the building, especially if glazing is planned in the future. Therefore, for such changes, an individual project is often developed. First, measurements are made, then the design and materials are determined, then the skeleton drawings are performed.

Installation work

The installation of the rafter system is carried out in the form of a metal frame, which can be taken out of the balcony somewhat if it is further glazed. The frame can be made of a metal corner 40x40mm or a pipe section 20x40mm. The execution of the frame from the pipe is considered more reliable. The attachment of the frame to the wall of the building must also be reliable. Anchor bolts are used here , which are mounted on the wall. The installation of the rafter system must be done taking into account the permissible load on it. It is also necessary to take into account the weight of the future glazing, so as not to exceed the permissible load. After the reinforcement of the frame, work is done to cover the roof.

Application of various roofing materials

As a roofing material, metal tile, ondulin, cellular polycarbonate and sandwich panels are used. Each of these materials has its advantages. Cellular polycarbonate - the material is very light and well transmits light, and sandwich panels are characterized by good thermal insulation properties.

Much attention should be paid to the place where the roof joins the building wall, since leaks should not be allowed. If the installation of the roofing system is done using metal, then a wall is made in the wall and water drainage is attached to it. For sealing all joints are smeared with special mastic. If a rafter system is installed, where cellular polycarbonate is used as a roofing material, then a polycarbonate sheet or 8 mm thick is taken, if the insulation is made, or 24 mm thick, if it is to be produced. Cellular polycarbonate is designed specifically for installation outdoors, so on its outer surface is applied a layer that protects it from ultraviolet radiation.

Pitched roof

The structure of pitched roof consists in the following: a wooden frame with the crate made on it is mounted, it is laid with a roof from any chosen roofing material. Throughout the perimeter of the roof are mounted ebb. High and low ramps can be made. The only difference is in price. The lower option is cheaper. They perform their functions in the same way.
