Problems solved by technology

[0003] In the existing roof truss structure, steel pipes or shaped steel bars are usually connected in a back-to-back connection mode. The steel pipes or shaped steel bars that bear the load in the same direction are in different planes. A single steel pipe or shaped steel bar is subjected to axial tension and The pressure is also subjected to shear force and large bending moment, which reduces the stability and reliability of the overall structure

Abstract

This application relates to a building roof truss support structure and construction method, involves the technical field of construction engineering, solves the problem of large shear stress under the back-to-back connection of traditional truss members, including the first truss and two second trusses, two The two second trusses are perpendicular to the first trusses and are respectively located at both ends of the two first trusses; the first trusses include tie rods and a plurality of webs arranged parallel to the tie rods; The second truss includes four main tie rods perpendicular to the transverse tie rods, and a web is also arranged between the two main tie rods on the same side. In the present application, by setting the connection balls for connection, the shear stress and bending moment are reduced, and the stability and reliability of the overall structure are improved.

Description

technical field [0001] The present application relates to the technical field of construction engineering, in particular to a building roof truss support structure and a construction method. Background technique [0002] In the field of green buildings, in order to increase the structural span, strengthen the structural facade and enhance the aesthetics of the roof, the steel truss structure is widely used in the roof structure of the building. In contemporary buildings, the steel truss structure is often used in large-span In public buildings such as factories, exhibition halls, stadiums and bridges. The truss structure can be prefabricated in advance and assembled at the construction site, which is convenient for construction. After the building reaches its service life, the truss structure can be recycled, which greatly saves building materials. In the roof truss structure, steel pipes or shaped steel bars are often used as basic components for assembly and welding to ac...
