SUSPENDED ROOF OF BUILDING OR STRUCTURES Russian patent published in 1998 - IPC

FIELD: construction, in particular, suspended roof of buildings or structures, both stationary and transformed in the course of operation. SUBSTANCE: suspended roof includes membrane (metal, plastic, canvas) attached to supporting contour whose lower part is reinforced with two-chord guy trusses. Grate is secured to truss by yielding spring ties whose rigidity in tension is considerably lower than that of joined members. It allows reduction of possible nonuniformity of tension of roof members in mounting and their overloading in the course of operation. Offered is also version of structural solution in which truss chords are connected by rigid ties and in upper and/or lower chords of truss, yielding spring inserts are built in. Attachment of membrane to supporting contour may be rigid or regulated. EFFECT: reduced nonuniformly tension of roof separate members on mounting and their overloading in operation, especially, in use of membrane made of highly deformed materials (plastic, canvas) and also for large-span roofs. 4 cl, 4 dwg
