1. General Structural and Technological Solutions

The building columns are solid. The section of the column is a rolling I/O.

Rafter trusses are made of rolling profiles: upper and lower belts - from wide-beam taverns; posts, braces and elements of sprengel - from corners. Rods in units are welded by semi-automatic in CO2 medium. Installation joint is made on welding. Runs on trusses are made from rolling channels. The coating is made of three-layer plates with metal skins and a middle layer of insulation.

The beam cage of floors inside the building is made of rolling and welded I-beams. Steel flooring is laid along the runs.

Mounting connections of trusses and beams with column are made on bolts of normal accuracy.

The columns are fixed to the foundations on anchor bolts, the diameter of which is taken as per.
