Design and construction of buildings and structures from light metal structures

Additional information:

Single-story industrial buildings with a span of 18 and 24 m are erected from lightweight metal structures. The column pitch in the outer rows is 6 and 12 m, in the middle – 12 m.
Buildings with a structural covering made of rolled sections or pipes have become widespread. The columns in such buildings are made of rolled or welded I-beams, from pipes with a diameter of 325-530 mm. Crane runways are welded I-beams. The covering is a spatial structure assembled from rolled angles or pipes. The elements of the structure are connected at the nodes using high-strength bolts, welding, hemispheres with internal threads. Trusses made of round pipes are designed for the installation of a lightweight covering made of profiled steel sheet on them.
Rafter structures for trusses made of round pipes with a column pitch of 12 m have a triangular outline. Their belts are made of round pipes, and the posts are made of rolled I-beams reinforced in places. The purlins are made of rolled channels with a cross-section height of 200-250 mm, depending on the estimated load. In necessary cases, especially in valleys, reinforced purlins can be used or consist of two channels. With a truss pitch of 12 m, the purlins are arranged as a lattice type. They have a triangular shape, the upper chord is made of paired rolled channels, and the lattices are made of single cold-formed ones. Buildings made of light metal structures are intended for enterprises of mechanical engineering, light, food and woodworking industries.
