AI Technical Summary

Technical Problem

Traditional concrete beam-column connection methods suffer from problems such as difficulty in controlling welding quality, long construction period, serious environmental pollution, and difficulty in guaranteeing quality, making it difficult to meet the needs of modern prefabricated buildings.

Method used

Sleeve 1 and Sleeve 2 are fitted onto the steel column. The pre-positioning of the concrete assembly beam is achieved through traction plates, screws, and nuts. Combined with the limiting mechanism of insert blocks and stops, a multi-level connection and limiting mechanism is formed to avoid welding operations.

Benefits of technology

It simplifies the construction process, improves construction efficiency, ensures the stability and safety of connections, reduces environmental pollution, and enhances the quality and reliability of building structures.
