Cable strut assembly type joint

Abstract

The invention discloses a cable strut structure assembly type joint. The assembly joint is composed of convex circular plates with annular tracks, lug plates, a supporting rod and bolts; two welding lug plates with holes are arranged on the joint, and the supporting rod is welded below the joint; two convex circular plates with annular rails and three straight plates with sliding track and three straight plates provided with sliding rails are arranged at the upper part of the joint, and are connected by screws through adjusting the inhaul cable angle of a cable strut structure in the construction process; and the lower part of the joint is connected with a pressing rod by connecting the bolt with a central body through a flange sheet, and the pressing rod is connected by connecting the flange sheet with the bolt; According to the cable strut structure assembly type joint, on the premise that the stress performance is guaranteed, standardization of part of assembly components provides convenience for factory machining and manufacturing and on-site fabricated construction, meanwhile, the types of joints in the structure are reduced, and the construction cost of the structure is reduced; and the cable strut structure assembly type joint is mainly applied to the cable strut structure and other rib annular cable dome structures.

Description

[0001] Technical field [0002] The invention belongs to an available node of a cable-strut structure, and relates to an assembled node of a cable-strut structure. Background technique [0003] The cable dome structure is a full-tension system with extremely high structural efficiency. Since the entire structure is in tension except for a few compression bars, the structure itself fully exerts the strength of the material. In recent years, due to the development of modern structural theory, computing technology, and new materials, a good theoretical and technical foundation has been laid for the promotion and application of cable dome structures. The development of the cable dome also promoted the research and development of connecting nodes. Nodes are a very important part of the spatial structure. During the development of the spatial structure, various nodes emerge in endlessly. Among these nodes, some nodes have not been applied to actual cases due to their short appeara...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide an assembled node, which can be used in the node form of the rib ring cable dome structure, so as to overcome the disadvantages of difficulty in adjusting the cable angle, complex node structure and inconvenient processing during the construction process.
