If it is decided that the installation of the roof truss system should be done independently, it should be understood that there is nothing difficult in this. But still this design should be installed without any errors. First of all, the truss system is an engineering structure that protects the house from environmental influences. The durability and reliability of the roof structure directly depends on how well the installation will be done.
The main task of the truss system is to support the entire weight of the roof and its reliable protection from wind and snow. When calculating it, it is necessary to take into account the peculiarities of the location of the house and the type of roof chosen. In this case, it is worth remembering the margin of safety. Without taking into account this indicator, it is impossible to start work. truss deviceroof system with a certain level of rigidity is achieved by fastening its elements - the frame with the building box.

It is worth noting that the first part of this list will not allow you to create a reliable and durable mount, so it is not recommended to use it. Bolts should also not be used as fasteners, because the holes created for them reduce the level of stability of the structure. The device of the roof truss system begins with leveling the surface of the walls. This is done using a screed, on which a waterproofing layer and a Mauerlat are laid. Next, a supporting sub-rafter structure is created from racks, girders and struts. Initially, the extreme rafters are installed, after which intermediate rafters can be installed.
The distance that should be between them depends on the design of the entire system and on the bearing capacity of the crate. For the roof, the so-called pie is used, consisting of four layers: vapor barrier, thermal insulation, waterproofing and roofing material. In order for a wooden product to be used for a long time, it is necessary to provide it with proper ventilation.
The installation of the roof truss system is carried out at the construction site near the house and requires a lot of time and labor. Shape and slopestructures can reduce the list of materials required for roofing.
In addition, the method of installation, the service life and the time of the first repair depend on this. To install the design of truss systems in the construction markets, there are many materials that are suitable in quality and characteristics. In addition, in the selection process, it is worth paying attention to their service life. They must be consistent with each other. In the case when the installation of the truss system will be carried out by a beginner, you should think twice before starting to do everything yourself.
