AI Technical Summary

Technical Problem

The existing composite beams are too complicated to fix and cannot adjust the height of the two ends, resulting in overall structural instability.

Method used

The system employs prefabricated composite beams with inverted T-sections that do not require support. Through the design of side bracing components, height adjustment components, and connecting components, the system utilizes embedded frames, bolts, and adjusting threads to achieve rapid fixing and horizontal adjustment of the beams, ensuring a firm connection between the beams and the walls.

Benefits of technology

It enables rapid installation and horizontal adjustment of composite beams, enhances the stability and robustness of the overall structure, and simplifies the fixing process.
