Design and construction of buildings and structures made of light metal structures.
Load-bearing structures, the strength of which is increased due to the use of high grades of metal or effective profiles, and the enclosing elements are made of thin sheet metal with effective insulation, are called lightweight.
One-story industrial buildings with a span of 18 and 24 m are erected from light metal structures. The column spacing in the outer rows is 6 and 12 m, in the middle ones - 12 m.
Buildings with a structural covering made of rolled profiles or pipes have become widespread. Columns in such buildings are made of rolled or welded I-beams, pipes with a diameter of 325-530 mm. Crane beams are welded I-beams. Covering is a spatial structure assembled from rolled angles or pipes. The structural elements are connected at the nodes using high-strength bolts, welding, and hemispheres with internal threads. Trusses made of round pipes are designed to be covered with a light covering of profiled steel sheet.
Rafter structures for trusses made of round pipes with a column spacing of 12 m have a triangular shape. Their belts are made of round pipes, and the racks are made of rolled I-beams reinforced in places.
The purlins are made from rolled channels with a section height of 200-250 mm, depending on the design load. In necessary cases, especially in valleys, the purlins can be reinforced or consist of two channels. With a truss pitch of 12 m, the purlins are made of a lattice type. They have a triangular shape, the upper belt is made of paired rolled channels, and the gratings are made of single cold-formed ones.
Buildings made of light metal structures are intended for mechanical engineering, light, food and woodworking industries.
