Spoke type single and double layer mixed cable net structure

Abstract

The invention discloses a spoke type single and double layer mixed cable net structure. The spoke type single and double layer mixed cable net structure comprises a spoke type single-layer cable net,a spoke type double-layer cable net and a compressive outer ring truss; the spoke type single-layer cable net comprises a single-layer cable net annular cable and single-layer cable net radial cables,one ends of the single-layer cable net radial cables are connected with the single-layer cable net annular cable, and the other ends of the single-layer cable net radial cables are connected with thecompressive outer ring truss; the spoke type double-layer cable net comprises double-layer cable net upper annular cables, double-layer cable net lower annular cable, double-layer cable net upper radial cables, double-layer cable net lower radial cables and strut assemblies arranged between the upper annular cables, the lower annular cables and the radial cables; and one ends of the double-layercable net upper radial cables and the double-layer cable net lower radial cables are connected with the double-layer cable net upper annular cables and double-layer cable net lower annular cable correspondingly, and the other ends of the double-layer cable net upper radial cables and the double-layer cable net lower radial cables are anchored to the compressive outer ring truss. The single and double layer mixed cable net structure is formed by combining the single-layer cable net and the double-layer cable net, achieves the asymmetric architectural appearance, has the characteristics of simple structure and see-through beautiful appearance of the single-layer cable net, and meanwhile has the advantage of high bearing capacity of the double-layer cable net.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a spoke-type single-layer and double-layer hybrid cable-net structure suitable for stadium roofs. Background technique [0002] The spoke-type cable net structure is a relatively new structural form, which is mainly composed of a tension inner ring, a compression outer ring and radial cables connecting the inner and outer rings, forming an overall self-balancing system. No additional foundation anchoring is required, and the force transmission is direct and efficient. The roof of this type of structure is often covered with membrane materials, which has the characteristics of light weight, strong spanning ability, rapid on-site construction, and simple and beautiful appearance. [0003] According to the number of radial cable layers, the spoke-type cable net structure can be divided into two types: single-layer cable net and double-layer cable net. ...

AI Technical Summary

Problems solved by technology

[0005] The spoke-type single-layer cable net has a simple structure and a transparent and beautiful appearance, but its vertical stiffness is poor and its bearing capacity is weak

The vertical stiffness and bearing capacity of the spoke-type double-layer cable net are stronger than that of the single-layer cable net, but the structural permeability is not as good as that of the single-layer cable net.

At the same time, single-layer cable nets and double-layer cable nets are designed to meet their own internal force balance and have a single structure, which cannot be widely adapted to complex and changeable architectural schemes.
