Brief Instructions for Fabrication and Installation of Coating Elements

Flooring designs depend on their purpose. Depending on the material of the roof, plank or bar flooring is used in the coating. In the coatings of heated buildings, a single board flooring is used to lay insulation. Boards are connected to each other in a bottomhole, their thickness is determined by calculation.

Under adverse climatic conditions, it is advisable to make wooden flooring and skins from shields prepared in advance at factories. The dimensions of the latter are set depending on the pitch of the runs, the height of the building floor, transportation and installation conditions. Boards of shields are sewn with nails using strips. Against wetting during construction, it is recommended to glue the outer face of the shields with a layer of bituminous cardboard, which will serve as vapor insulation. Boards are made manually and therefore it is not advisable to recommend them for mass construction.

Runs of coatings and suspended floors are designed from boards, bars or logs in the main form of single-span beams. In the covers of buildings of large length, with a small slope of the roof, continuous runs of paired boards or plates are used.

In cantilever and continuous runs from paired elements, joints are arranged in the span in the zone of the smallest bending moments under the assumption that the time load is evenly distributed over all runs. In continuous runs from paired joint elements, they are placed in a run-down at a distance of x = 0.21l from the support, i.e. each joint of one element is covered by a whole other element. Along the length of the run board they are connected with nails arranged in staggered order after 50 cm, and nails are installed in the joint according to the calculation.
