Beam string and cantilever truss combined roof truss and construction method

Abstract

The invention relates to a beam string and cantilever truss combined roof truss and a construction method. The beam string and cantilever truss combined roof truss comprises a beam string assembly andcantilever truss assemblies assembled on the two sides of the beam string assembly, wherein the beam string assembly comprises two beam string main beams of an arc-shaped structure; a plurality of beam string main beam supporting rods are transversely assembled between the two beam string main beams; the left ends and the right ends of the two beam string main beams are each provided with two supporting connecting frames capable of being connected to the same plane; and the two sides of the two supporting connecting frames are fixedly arranged on the cantilever truss assemblies correspondingly. The beam string and cantilever truss combined roof truss is simple in structure and ingenious in design, the combined roof truss between the beam string assembly and the cantilever truss assembliesis a novel design for a building roof, and a roof area over the column is increased; and meanwhile, the beam string and the cantilever trusses mutually borrow force with a support as a fulcrum, materials are saved, the development requirement of modern buildings is met, and the beam string and cantilever truss combined roof truss is a novel roof truss combined system.

Description

technical field [0001] The invention belongs to the technical field of building construction devices, and in particular relates to a combined roof truss of tension beams and cantilever trusses and a construction method. Background technique [0002] With the development of society, while the self-private space is gradually expanding, the demand for public building space such as cultural centers, gymnasiums, theaters and other buildings is also increasing day by day. The roof structure has attracted more and more attention. The traditional building system can no longer meet human needs. The traditional large-space roof structure only studies and applies the space structure in the column, such as the span height, and often ignores the column. Utilization of the outer space area.

Problems solved by technology

[0003] In recent years, with the needs of my country's economic construction and the improvement of people's living standards, the building system has become more and more high-rise, large space, and long-span. However, the existing structural system is single, most of which are pure string beams and pure trusses. Although the application can meet the problems of safety, economy and high efficiency, it lacks artistic elements and aesthetic feeling, and does not integrate and utilize structural resources to play its due role
