Steel sheet strip and cable net structure

Abstract

The invention discloses a prestressed steel sheet strip and cable net structure. The prestressed steel sheet strip and cable net structure comprises steel sheet strips, bearing cables and a stressed ring beam. With the stressed ring beam as a frame, the steel sheet strips and the bearing cables form crossed longitude lines and latitude lines in the frame. The steel sheet strips and the bearing cables are connected through three-ply type joints, the steel sheet strips and the stressed ring beam are connected through fork lug type joints at supports, and the bearing cables and the stressed ring beam are connected through fork lug type joints at supports. Purlin braces are installed on the steel sheet strips in a bolting or welding mode so as to connect purlins, and a rigid roof can be conveniently installed on the purlins directly. According to the prestressed steel sheet strip and cable net structure, the use quantity of the cables and cable clamps is reduced, and the structure construction cost is effectively lowered; torsion or deflection is not likely to occur, and construction is convenient; besides, the upper rigid roof material can be easily installed after forming.

Description

technical field [0001] The invention discloses a prestressed structure, in particular a steel plate belt cable net full tension structure, which belongs to the technical field of civil engineering space structure. Background technique [0002] With the continuous development of building materials, design theories, and calculation methods, there are more and more forms of large-span spatial structures that are simple, efficient, and convenient for construction, and the advantages of prestressed structures are becoming more and more prominent. In recent years, the application of long-span cable net structures in public buildings is increasing. The main reason is that the cable net structures make full use of the high-strength tensile properties of the cables. The building is beautiful, light and full of tension. It is an efficient space structure. [0003] The conventional cable net structure is composed of two groups of orthogonal cables with opposite curvatures that interse...

Problems solved by technology

[0006] The invention replaces the stable cables in the conventional cable net structure with steel strips, which has the advantages of the traditional cable net flexible structure, belongs to the full tension structure system, and the steel strip itself has a certain in-plane and out-of-plane rigidity and less steel consumption. At the same time, it overcomes the difficulty of applying rigid roofs in flexible structures, solves the problem of complex structure and high cost of the combination of conventional cable net structures and rigid roofs, and can adopt a simple construction method without supports
