Embodiment Construction

[0022] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0023] A three-dimensional compression member of a tension structure, comprising a first regular tetrahedral-based member, a second regular tetrahedral-based member, a regular hexahedral-based member and a cube-based member, the first regular tetrahedral-based member, the second regular tetrahedral-based member Positioning holes are provided at vertices of the regular tetrahedron component, the regular hexahedron-based component and the cube-based component.

[0024] Such as figure 1 As shown, let the centroid O of the regular quadrilateral be the origin, and the four vertices of the regular quadrilateral are and Where a is a constant related to size (a>0), and the first tetrahedron-based component is formed by connecting the centroid O with four vertices A, B, C, and D respectively.

[0025] Such as figure 2 As shown, let the centro...

Abstract

The invention discloses three-dimensional compression members of a tension structure. The three-dimensional compression members of the tension structure comprise first regular tetrahedron-based members, second regular tetrahedron-based members, regular hexahedron-based members and cube-based members, wherein the vertexes of the members are provided with positioning holes which are connected through ropes, the ropes comprise the ropes perpendicular to the extending directions of the members and the ropes parallel to the extending direction of the members, and the included angles formed between the ropes perpendicular to the extending directions of the members and the ropes parallel to the extending direction of the members are greater than 90 degrees. The three-dimensional compression members expand the range of the tension structure, and one-dimensional compression members of the tension structure are expanded into the three-dimensional compression members. Control over a spatial structure is simpler, and the three-dimensional compression members of the tension structure overcome the defects as for a bar and rope structure, that the number of compression bars is large, prestressing force of structural arrangement needs to be considered, and the compression bars can lose stability possibly. The ropes among the members are relatively independent, the connection ropes between every two adjacent members provide the prestressing force for connection of every two adjacent members, and the spatial structure is easy to control and not prone to losing stability.

Description

technical field [0001] The invention relates to a tension structure, in particular to a three-dimensional compression member of the 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 rod-cable tension structure in 1965.) Tension in a broad sense covers a wide range. Fuller believes that the operation of the universe is carried out according to the principle of tension as a whole, that is, gravity is a balanced tension network, 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...
