Coursework - KD covering a one-storey production building 60 x 12 m

It is necessary to design wooden structures of the insulated coating of a one-story building under the following conditions:
– span of the building – 12 m;
– length of the building – 60 m,
– frame walls;
– construction area by weight of snow cover – IV;
– wood – Krasnoyarsk cedar;
– thickness of glued boards – 33 mm;
– wood grade – 1 (К26);
– roof material – welded roll;
– the type of coating is cold.
As load-bearing structures of the coating, we accept glued beams with a step of 6 m, continuous runs through them through 1.5 m, along which the bearing boards are laid; between the bars nailed to the supporting shields at an angle of 45 °, insulation is placed - mineral felt. Roofing boards are laid on the bars, on them - three layers of roofing material on hot bitumen.
In the coatings of heated buildings, a single board deck is used to lay insulation. The boards are connected to each other side by side or in a quarter, their thickness is determined by calculation.
For the roof of wavy asbestos-cement or fiberglass sheets, tiles, roofing metal, decking is arranged in the form of a crate of bars located from each other at a distance depending on the type of roofing material. Wall fencing is also solved.
Transparent fences can occupy the entire surface, or fill part of it in combination with wavy sheets of asbestos cement or metal. In the latter case, the wave sizes of transparent and non-transparent sheets should be the same.
