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 equidistantly and staggered 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 The adjacent holes in the vertical direction are connected with prestressed ropes 4, and the prestressed force of the tensioning mechanism is controlled by adjusting the leng...

Abstract

The invention discloses a double-layer fold-line-shaped large-span tension structure. The tension structure comprises fold-line-shaped compression members and tension ropes, wherein a plurality of straight bars are connected end to end to form each fold-line-shaped compression member, the tension ropes include horizontal fixing ropes and vertical prestressing force ropes, the fold-line-shaped compression members which are connected end to end are in the same spatial plane and arranged at equal intervals in a staggered mode, and each hole of each fold-line-shaped compression member is fixedly connected with an adjacent hole in the horizontal direction through one of the fixing ropes and fixedly connected with an adjacent hole in the vertical direction through one of the prestressing force ropes. The double-layer fold-line-shaped large-span tension structure is simple in structure, reasonable in stress and light in weight, the prestressing force can be conveniently and completely controlled through the ropes in the vertical direction, the span extension of the structure can be achieved by increasing the number of the straight bars on the fold lines, the double-layer fold-line-shaped large-span tension structure is convenient to assemble and detach and belongs to a green building which can be rapidly installed and detached, and the fold-line-shaped compression members can be folded or detached to transport and store.

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...
