AI Technical Summary

Technical Problem

The existing steel structure square tube columns have poor welding quality during connection, and the connectors cannot be reused, which affects the load-bearing capacity and overall stability.

Method used

The system employs a welded structure comprising horizontal and vertical tubes and connecting components. The connecting components consist of connecting blocks, top blocks, extension sleeves, and telescopic rods. Rapid assembly and fixation are achieved through triangular holes and slot structures. During welding, current, voltage, and temperature are strictly controlled, and root pass welding, filler weld welding, and cover pass welding are performed.

Benefits of technology

It enables rapid assembly and disassembly of square tube columns, improves welding quality, structural stability and load-bearing capacity, and reduces usage costs.

Abstract

This invention discloses a welded steel square tube column structure, relating to the technical field of square tube columns in steel structure buildings. It includes a first horizontal square tube, a second vertical square tube, and a third horizontal square tube, as well as a connecting assembly. Each of the first and second horizontal square tubes has a triangular hole at one end. By incorporating the connecting assembly, this invention not only allows for the rapid installation and fixing of the first, second, and third horizontal square tubes, but also enables their disassembly and reuse, improving the practicality of the structure and reducing its operating costs. Furthermore, the first and second horizontal square tubes are welded together, and the vertical tubes provide support and constraint for them. An inner sleeve plate further supports the first and second horizontal square tubes, and telescopic rods one and two also provide further support. Through the combination of these structures, the welding quality and service life of the square tube column are ensured, improving the overall stability and load-bearing capacity of the structure.
