The invention relates to the field of construction and more particularly - to the bearing metal structures covering industrial and public building. Each individual coating triangular truss is composed of two tubular upper belts and one lower, as tubular belts interconnected by diagonal bars. All have a tubular belt pentagonal cross section and each comprise a rigidly interconnected open U-bracket. Diagonal lattice is formed of single parts, and placed directly on the shelves of fixed shelves waist corners, butt are directed downwards. The walls of the U-sections of the upper and lower belts arranged horizontally in this case. The upper zone of the walls of shelves combined sills Bent. This design allows for a rigid (besfasonochnoe) conjugation belts and braces and thus, reduce the overall deformability triangular truss. Direct placement shelves diagonal lattice on the shelves over the belt simplifies the technology and the complexity of manufacturing and reduces the calculated lengths of diagonal elements of the lattice, thereby reducing the metal content for bracing limited limiting flexibility.
