Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as image 3 As shown, the present invention provides a double-layer zigzag large-span tension structure, including zigzag compression members and tensioned ropes;

[0027] The broken-line compression member is formed by connecting several straight rods 1 end to end;

[0028] Described tension rope comprises the fixed rope 3 of horizontal direction and the prestressed rope 4 of vertical direction;

[0029] The end-to-end broken-line compression members are arranged in a staggered equidistant manner in the same space plane, and each hole of the broken-line pressure member is connected to the adjacent hole in the horizontal direction with a fixed rope 3, and each hole is connected to the horizontally adjacent hole. The adjacent holes in the vertical direction are connected with the prestressed rope 4, and the prestress of the tension...

Abstract

The invention discloses a double-layer zigzag large-span tension structure. The tension structure includes a zigzag compression member and a tension rope; the zigzag compression member is formed by connecting several straight rods end to end; The tension ropes include fixed ropes in the horizontal direction and prestressed ropes in the vertical direction; the folded line-shaped compression members connected end to end are arranged in an equidistant staggered manner in the same space plane, and the folded line-shaped compression members Each hole is connected with the adjacent holes in the horizontal direction by a fixed rope, and each hole is connected with the adjacent holes in the vertical direction with a prestressed rope. The present invention has simple structure, reasonable stress and light weight; the prestress control is convenient and can be completed by adjusting the ropes in the vertical direction; the span extension of the structure can be completed by increasing the number of straight rods on the broken line; the loading and unloading is convenient, It is a green building that can be quickly installed and dismantled, and the folded compression members can be folded or disassembled for transportation and storage.

Description

technical field [0001] The invention relates to a rod and cable tension structure, in particular to a double-layer zigzag long-span tension structure. Background technique [0002] The tension structure is a special structural system composed of discontinuous compression members and continuous tension cables. Its concept was first proposed by Snelson and Fuller in the 1960s. Snelson applied for a U.S. patent on the traditional tension structure in 1965. The generalized tensegrity covers a very wide range. Fuller believes that the operation of the universe is carried out according to the principle of tensegrity, that is, gravitation is a balanced tension net, and each planet is an isolated point in this net. Tensile structure is considered as a self-supporting and self-stressed space grid system composed of a group of discontinuous compression members and a set of continuous tension units. Due to the inherent characteristics of the tensegrity structure in line with the law...
