In the construction of the frame of any house, the construction of the roof is the final stage. Its strength and reliability depend on the correct installation of each element. Truss trusses play a special role. This element of the roof is very laborious and requires serious attention to itself. Increasingly, when building houses, people resort to buying roof parts already assembled at the factory. However, this is too costly, and many are trying to cope on their own.
Today you can find different truss trusses that are in good harmony with the overall design of almost any roof. The purpose of such an element, as a rule, is to bear the weight of the roofing material. If the trusses are of the factory type, then all aspects must be taken into account in order to properly create the base for the crate. In other words, truss trusses - a set of bars and boards - must be connected in the prescribed manner according to the roof project. For fasteners, bolts, nails and gear-ring type dowels are used.
When installing finishedroof trusses, beams are used as supports to cover the main frame, on which the ceiling or flooring of the second floor is hemmed. They are cut into beams and bolted together for security.
Quite common in the construction of wooden floor trusses. The construction system is very rigid, a well-dried timber of strong wood is used. The bars are cut to the desired length and laid so that they are parallel; as a rule, these are two blocks. Then, long blocks are connected with short bars of the same dimensions, thereby forming the required size of the overlap elements.
Someone is trying to independently carry out truss trusses at home. But it should be understood that without experience and knowledge, it will not be so easy to build such an important element. In any case, you will have to turn to specialists for advice. By origin, farms can be:
- wooden;
- metal;
- reinforced concrete.
If, nevertheless, you are persistent in your desire to try to make this roof element yourself, then you need to adhere to the following rules:
- N
- All finished roof trusses are rigidly fixed to the support beams using anchor bolts or metal brackets. Do not forget thatthe rafter leg should have a protrusion of 30 cm beyond the Mauerlat.
- If too wide spans for trusses are formed, in particular, more than 4.5 meters, then it is necessary to come up with additional wooden supports for the truss elements.
you need to study the fasteners of the rafter elements, because the strength of the roof will depend on the stability of the rafters. Assembly options are different; you can assemble in the way that is more convenient for you, but subject to the exact dimensions.
Each element requires serious attention and elaboration. Bolted connections must be tightly tightened and the structure must be stable. Don't be alarmed if you find that the truss trusses will hang loose even after fastening. They will get real rigidity in the overall frame when the crate and roofing material are laid down.
