AI Technical Summary

Technical Problem

When steel beams are spliced ​​with concrete beams, they are easily affected by wind and may sway, leading to misalignment.

Method used

An embedded side plate is pre-embedded on the surface of the concrete beam, and a base plate is installed perpendicular to it. Positioning components such as positioning plates and limiting baffles are installed on it. The steel beam is aligned with the concrete beam by the snap-fit ​​and rotation guidance of the positioning plates with the web of the steel beam.

Benefits of technology

This effectively avoids misalignment between steel beams and concrete beams caused by external forces such as wind during the splicing process, ensuring splicing accuracy.
