If the structure has a small width, A-shaped trusses are installed without a ridge girder. The horizontal lintel (bolt) gives the structure rigidity and reduces the load on the spacer, which is transmitted to the walls. The attachment of truss legs in the upper part is enhanced by a wooden or metal plate lining.
The lower part of the rafters can rest on the mauerlat with the cut-off end – in this case, the truss system is performed without overhang. If the project provides for the construction of a roof with an overhang of rafter legs, a recess is cut in the lower part of the rafter so that the rafter of the horizontal part of the cutout rests on the power plate.
The construction of the roof of the house can be done without laying the wall cover on long walls. In this case, beams are mounted across the long walls, and the length of the beams exceeds the width of the building. (more…)
