FIELD: building structures. SUBSTANCE: unified pyramidal plate members F serve as the base of the structure. Each member consists of thin steel plates 1 of a triangular shape interconnected by lateral faces 2. Pyramids formed in such a way are combined in a single spatial block interconnected at lower edges 3, as well as by means of a cross system of bars 4 at the tops. Plate members 1 combine the bearing and guard functions, which saves material up to 10 to 15% as compared with the known bar structural roofing. Other variants are possible including triangular and hexagonal pyramids with a triangular or cellular bar system meeting the specific lay-out requirements with a different degree of architectural expression. EFFECT: improved design. 4 cl, 7 dwg |
