Integrate-assembled transformable backbone joint for spatial structure

Abstract

The invention relates to an integrate-assembled transformable backbone joint for a spatial structure, which comprises a backbone, a plurality of convexly extended connecting seats and a plurality of positioning parts, wherein the backbone is an axial rod in a scheduled form and is the main body of the entire joint; each of the convexly extended connecting seats is provided with a seat body arranged on the peripheral surface of the backbone, the surface of the seat body is provided with extending convex bodies for connection which are radially and convexly arranged along the backbone outward and are provided with a plurality of layers with different position direction, and the extending convex bodies in different positions comprise same or different forms; and at least two positioning parts are axially arranged at the upper end and the lower end of the backbone respectively to make the upper end face and the lower end face of the backbone form an axial joining part, an upper positioning part and a lower positioning part fix the convexly extended connecting seats on the backbone to assemble a joint, and by using the axial joining part and the radial extending convex bodies with different azimuth angles corresponding to each joint, axial tubes and lateral connecting parts form the spatial structure with a scheduled pattern.

Description

technical field [0001] The present invention relates to a joint, in particular to a joint with a backbone integrated with a protruding socket, which can change the form and assembly relationship of the backbone and the protruding socket according to different structural configurations, and can adapt to various structural requirements. The integrated assembly transformable backbone joint used in the space structure. Background technique [0002] The joints of the structure are used to connect the combined components, making them into rigid connections or hinged joints, so as to transfer and distribute the load on each component. Nowadays, there are two methods of structural joints, direct and indirect. The direct method refers to the method of connecting components without other special connection structures, such as directly welding the beams to the columns, or lapping the beams. Then it is combined by welding; the indirect method is to add transitional components or specia...

Problems solved by technology

[0003] From the above description, it can be seen that the joints of the current structure, whether direct or indirect, do not have the randomness of the assembly orientation when the structure is composed, and the joint components do not have convertibility, and at the same time, the components do not have a certain degree of flexibility. degree of freedom, moreover, at the joint node, generally different joint forms cannot be used, and they coexist on the same node, so the structure construction has a higher complexity, and it cannot meet the multiple needs of the structure, so there is still improvement space
