Suspended support arch shell structure

Abstract

The invention relates to a suspended support arch shell structure comprising a net shell, an arch, a stay bar, a radial pull rod and an annular pull cable. The arch is replaced by a part of rod members of the net shell, and the lower part of the net shell structure is provided with a vertical stay bar, the radial pull rod and the annular pull cable to form the suspended support arch shell structure. The net shell adopts a single layer of spherical net shell, a single layer of ellipse spherical shell, double layers of spherical net shell and double layers of ellipse spherical shell. The invention has the advantages of overcoming the defects of poor stability of the single layer of net shell or the double layers of net shell with thinner thickness and small spanning capability and the defects of difficult processing of horizontal push force of an arch springing support base of an arch structure by fully utilizing matured installation technology of the net shell, strong spanning capability of the arch structure and high intensity tension performance of a cable material, thereby a structure system with large spanning capability, favorable stability, reasonable economy and convenient construction is formed, and the invention is universally suitable for common industry and civil architecture, in particular to large-spanning space structure systems, such as convention centers, stadiums and the like.

Description

technical field [0001] The invention relates to a novel space steel structure in a building structure, more specifically, to a suspensive arch shell structure composed of a reticulated shell, an arch, a stay cable and a strut in the field of building structures. Background technique [0002] Reticulated shell and arch structure are a kind of space structure system commonly used in engineering. Reticulated shell has the advantages of beautiful architectural shape, reasonable structural force, mature calculation and design software, and high degree of mechanization of processing; arch structure has reasonable force and can span large span. However, when the reticulated shell and the arch are used as the structural system of the building, there are the following deficiencies: [0003] (1) Single-layer reticulated domes or double-layer reticulated domes with small thickness are difficult to achieve large spans due to their poor out-of-plane stability; [0004] (2) When a doubl...

AI Technical Summary

Problems solved by technology

[0003] (1) Single-layer reticulated domes or double-layer reticulated domes with small thickness are difficult to achieve large spans due to their poor out-of-plane stability;

[0004] (2) When a double-layer or multi-layer reticulated shell with a large thickness is used, due to the large thickness of the reticulated shell, the amount of steel used in the structure increases and the structural cost increases

[0005] (3) When the sagittal height of reticulated shell and arch structure is small, the horizontal thrust of the support is large, which will cause a burden to the design of the lower structure;

[0006] (4) Due to the characteristics of the structural form itself, the arch structure is not suitable for spherical structures;

[0007] (5) There is an out-of-plane stability problem in the arch structure
