Problems solved by technology

However, the spanning capacity of the rigid roof is small, and it is necessary to add a secondary structure to support the roof and transfer the roof load to the main structure of the cable dome, which puts forward higher requirements for the spanning capacity of the secondary structure

Embodiment Construction

[0020] To design a secondary cable-net cable dome structure supporting a rigid roof, the basic steps are as follows:

[0021] 1) First select the rigid roof material, and preliminarily determine the basic size of the planar orthogonal secondary cable grid according to its spanning capacity, that is, the distance between the radial secondary cable and the circumferential secondary cable.

[0022] 2) According to the rigid roof material and the allowable deformation value of the secondary cable network, the span and initial prestress of the radial and circumferential secondary cables are preliminarily determined.

[0023] 3) Preliminarily determine the basic size of the grid of the main structure according to the spans of the radial secondary cables and the circumferential secondary cables, that is, the spans of the notochor and hoop cables in the main structure.

[0024] 4) Preliminarily determine the number of rings and radial widths of the main structure according to the span...

Abstract

The invention discloses a secondary cable net cable dome structure, which consists of a ridge cable, a broken line stay cable, an upper ring cable, a lower ring cable, an annular middle pressure lever, a radial middle pressure lever, a corner pressure lever and a secondary cable net. The secondary cable net cable dome structure can support a rigid roof, is a novel full-tension structure similar to a cable dome, and belongs to the field of spatial structures of civil engineering buildings. The secondary cable net is formed by orthogonal radial secondary cable and annular secondary cable planes, big grids of the upper part of a main structure consisting of the ridge cable and the upper ring cable are divided into small grids, and nodes of the secondary cable net are directly used as fulcrums of the rigid roof. The secondary cable net is supported on the surrounding ridge cable and the upper ring cable, and the supporting rigidity of the ridge cable and the upper ring cable is reinforced through the annular middle pressure lever and the radial middle pressure lever. Through the secondary cable net cable dome structure, the design idea of the full-tension structure is kept, the advantages of a cable dome structure are succeeded, the integral stability is better, and the selective range of the roof material is wider; and the structure can be popularized and applied.

Description

Technical field [0001] The present invention disclosed a new type of all -trial structure -the secondary network cable dome structure, which is based on the ridge, the folding line 斜, the upper ring cable, the lower ring, the ring of the ring, the radial middle pressure rod, the angle of the angle, the angle of the angle, the angle, the angleThe compression rod and the second cable network can be laid on the rigid roof material, such as glass panels and color steel plates.It belongs to the field of space in civil engineering. Background technique [0002] The conventional cable dome is a spatial comprehensive tension structure composed of ridges, diagonal cables, ring cables, and rods. Its simple structure, strong spanning ability, light weight, and high air are now promoted and applied in China.Due to the requirements of architecture and structure, the grid size between the cable dome components is large, which requires the roof system to have a good leap performance itself. The...
