Steel pipe truss hinged joint device

Abstract

The invention discloses a steel pipe truss hinging node device, which is mainly formed by a steep pipe truss, a rubber heel block, an embedded part and a concrete fixing device; the embedded part comprises a horizontal steel plate and steel bars vertically fixedly welded with the horizontal steel plate; the steel bars are arranged in the concrete fixing device; a support and a support transition plate which are integrally molded with the steel pipe truss are arranged at the lower end of the steel pipe truss; the rubber heel block is arranged between the support and the support transition plate by an anchor bolt; the support transition plate is fixed at the upper end of the horizontal steel plate in a welding mode. The steel truss hinging node device has the advantages that right angle hooks are arranged at the lower ends of the steel bars, thus greatly enhancing the friction between the embedded part and the concrete fixing device; the support arranged at the lower end of the steep pipe truss is welded with the steel pipe truss, so stressed centers of all steep pipes of the truss cannot be converged at one point, the existence of eccentric force at a node is avoided, the bearing force and rigidity of the hinging node are effectively improved, and the demands of the building field on the steel pipe truss hinging node are met.

Description

technical field [0001] The invention relates to a steel pipe truss device for construction engineering, in particular to a steel pipe truss hinge node device. Background technique [0002] Steel pipe truss, referred to as steel truss, refers to a truss mainly made of steel, which is mainly used in industrial and civil buildings such as industrial plants, warehouses, gymnasiums, exhibition halls, venues, terminals, stations, office buildings, etc., and steel pipe trusses are usually As the main component of the load-bearing structure in the above-mentioned buildings, three-sided, four-sided or multi-sided planar trusses are commonly used, but the center of gravity of the steel tubes of the usual steel tube trusses cannot meet at one point, and there is usually an eccentric force at the node. For large buildings and areas with strict seismic requirements, the bearing capacity and stiffness of hinge joints cannot meet the requirements. Contents of the invention [0003] The ...
