AI Technical Summary

Technical Problem

Existing beam-column connection methods in steel structure buildings have the following problems: large amount of on-site welding work, weld quality is greatly affected by the environment and the technical level of operators, welded joints are prone to brittle fracture, and traditional all-bolted joints have complex structures, increased steel consumption, and insufficient load-bearing capacity at the joints.

Method used

The structure adopts a bolted and welded quick-assembly mortise and tenon combination structure. The initial positioning of the beam is achieved through the column positioning groove. Combined with the split ring plate connector, beam through connection plate and bolts and pins, a mechanical interlocking and friction force transmission mechanism is formed, which reduces on-site welding and ensures connection reliability and seismic performance.

Benefits of technology

It enables rapid assembly of beam-column joints, reduces on-site welding operations, eliminates residual welding stress, improves construction speed and joint quality stability, ensures seismic performance and overall stiffness, and is suitable for complex engineering scenarios.
