AI Technical Summary

Technical Problem

In existing prefabricated buildings, the connection between beams and columns requires multiple bolts after being secured by connecting sleeves, resulting in low efficiency.

Method used

The connecting assembly, which includes a first wedge plate, a second wedge plate, and a cross brace plate, is combined with a diagonal tension mechanism and a filling mechanism. The stability of the connecting sleeve is increased by the cooperation of the second connecting column and the straight brace plate, and the gaps are filled with sealant to improve the stability and tensile strength of the connection.

Benefits of technology

This design enables a rapid and stable connection between the beams and columns, improving connection efficiency, enhancing connection stability and tensile strength, while reducing the space occupied under the beams.
