AI Technical Summary

Technical Problem

The existing steel structure column connection process is poor, and the welding method requires skilled workers and high-quality equipment, which is time-consuming and susceptible to previous work, affecting the construction progress.

Method used

Using an assembled steel structure column connection structure including a clamping connection mechanism and a top support mechanism, the upper and lower steel columns are quickly connected and disassembled through components such as hinges, annular grooves and support rods, and the drive mechanism and clamping connection mechanism are used to achieve rapid clamping. Tight and unlock.

Benefits of technology

It realizes rapid connection and disassembly of steel structure columns, reduces on-site construction time, improves connection progress, facilitates later disassembly and reassembly, and replaces the traditional welding method.

Abstract

The present invention belongs to the technical field of assembled steel structure columns, and in particular, is a connection structure of assembled steel structure columns, including an upper steel column and a lower steel column for assembly connection, the upper inner walls of the lower steel column and the lower steel column are both provided with an annular embedding groove, the lower steel column is provided with an annular mounting groove fixedly connected to the embedding groove, the inner bottom wall of the mounting groove is provided with a supporting mechanism distributed in an annular array, the upper steel column is provided with a clamping connection mechanism, and the upper end of the upper steel column is also provided with a driving mechanism linked with the clamping connection mechanism. The connection structure of the assembled steel structure column is characterized in that a guide rod connected by a large clamping block through a clamping rod first moves downward in a guide track groove, the clamping rod gradually opens to push the large clamping block against the inner arm of the embedding groove, and the small clamping block moves later, and is consistent with the movement trajectory of the large clamping block, so that the connection between the two clamping blocks and the embedding groove of the lower steel column does not fall off.
