AI Technical Summary

Technical Problem

In existing technologies, the way the load-bearing steel beam is fixed inside the well shaft cannot allow for free expansion and contraction, which makes it prone to cracking or breaking when thermally expanding and contracting, posing a safety hazard.

Method used

The limiting block and support plate, which are connected by a sliding snap-fit, provide displacement space for thermal expansion and contraction. The sliding snap-fit ​​between the limiting block and the support plate allows the load-bearing steel beam to slide inside the well, thereby compensating for thermal expansion and contraction.

Benefits of technology

This improves the safety of the load-bearing steel beams, avoids cracking or breakage caused by thermal expansion and contraction, and enhances safety.
