AI Technical Summary

Technical Problem

The existing cold-bending thick-walled steel beam and column node connections have problems such as poor seismic resistance, long construction period and difficult to guarantee quality, especially in the closed section, bolt tightening and cumbersome construction.

Method used

A new type of prefabricated cold-bending thick-walled steel single-sided bolt is used to connect the beam and column nodes, including rectangular cold-bending thick-walled steel columns, rolled H-shaped steel beams, connecting end plates, outer sleeves and single-sided bolts. Through the welding of the factory prefabricated outer sleeve and the cold-bending thick-walled steel column, the construction site directly uses single-sided bolts to connect the rectangular cold-bending thick-walled steel columns to the H-shaped steel beams with welded end plates.

Benefits of technology

Assembled construction with good seismic resistance is achieved, the problems of difficulty in tightening bolts and cumbersome construction in closed sections are solved, construction efficiency is significantly improved, and the impact on the environment is reduced.

Abstract

The present invention discloses a novel assembled cold-bent thick-walled steel single-side bolt connection beam-column node, comprising a rectangular cold-bent thick-walled steel column, a rolled H-shaped steel beam, a connecting end plate, an outer sleeve and a single-side bolt. The outer sleeve is sleeved and welded on the rectangular cold-bent thick-walled steel column, and a connecting end plate is welded to one end of the rolled H-shaped steel beam close to the rectangular cold-bent thick-walled steel column, and the side of the connecting end plate away from the rolled H-shaped steel beam is fitted with the side wall of the outer sleeve, and a plurality of single-side bolts connect the connecting end plate to the outer sleeve. The welding between the outer sleeve and the cold-bent thick-walled steel column and the rolled H-shaped steel beam and the connecting end plate is completed by factory prefabrication, and the rectangular cold-bent thick-walled steel column and the H-shaped steel beam welded with the end plate are directly connected by single-side bolts at the construction site, thereby realizing true assembly construction and solving the problems of difficulty in tightening bolts in closed sections and cumbersome construction. There is no on-site welding workload, which can significantly improve construction efficiency and has little impact on the environment.
