High-strength steel pipe truss steel structure

Abstract

The invention discloses a high-strength steel pipe truss steel structure which comprises four main rods, the four main rods are connected through a plurality of supporting frames, four three-way pipes are symmetrically installed in each supporting frame, and a reinforcing pipe is connected between every two adjacent three-way pipes through a clamping mechanism. The three-way pipe is connected with the outer side wall of the main rod through a positioning mechanism; the ends of the reinforcing pipes are inserted into the pipe sleeves, the clamping mechanisms extrude and fix the reinforcing pipes, and then the steps are repeated to fix other reinforcing pipes, so that bolts can be prevented from being used for fixing when the multiple reinforcing pipes are assembled, and the three-way pipes in the multiple supporting frames slide along the outer side walls of the four vertical rods; and then the three-way pipe and the vertical rod are fixed through the positioning mechanism, when the supporting frame needs to be disassembled, the three-way pipe and the vertical rod are separated through the positioning mechanism, and therefore workers can conveniently and rapidly assemble and disassemble the supporting frame.

Description

technical field [0001] The invention relates to the technical field of steel structures, in particular to a high-strength steel tube truss steel structure. Background technique [0002] Steel truss structure refers to a lattice structure composed of round rods connected to each other at the ends. The main rod and the reinforcing pipe are fixed by welding. The assembled type means that the main rod and the reinforcing pipe and between the two adjacent reinforcing pipes are fixed by bolts. When used in performing arts studios and other temporary construction sites, in order to facilitate the later For transportation and handling, most of the workers use assembled steel trusses for support. [0003] In the process of realizing this application, the inventor found that there are at least the following problems in this technology: in the process of using the assembled steel truss structure, since the bolts will corrode when exposed to water, when the bolts need to be disassemble...

AI Technical Summary

Problems solved by technology

[0003] In the process of implementing the present application, the inventors found that there are at least the following problems in this technology: During the use of the assembled steel truss structure, the bolts will be corroded when exposed to water, and when the bolts need to be disassembled and twisted, the bolts will be rusted. This increases the difficulty for the staff to disassemble the bolts, and due to the large number of reinforced tubes, when disassembling and installing the bolts, it will increase the installation time of the staff, thereby reducing the installation and maintenance of the steel truss structure. Disassembly efficiency, can not be more convenient for staff to operate
