AI Technical Summary

⚠Technical Problem

The existing wall ties for safety ladders on bridge piers have problems of material waste and high installation risk. In particular, the embedded steel plates cannot be removed, resulting in poor appearance quality and unstable connection to the tie rods, posing safety hazards.

⚗Method used

It adopts a wall-connected locking mechanism and a ladder-reinforced fixing mechanism, and achieves convenient assembly and disassembly through bolt connection. It can adapt to different pier column sizes, and uses an open-type enclosed structure to avoid pre-embedded steel plates. Combined with a limit cylinder and a rope system, it ensures operational safety.

🎯Benefits of technology

It improves installation efficiency and material turnover rate, reduces installation risk factor, ensures the stability and safety of wall tie devices, and avoids material waste and appearance corrosion problems of embedded parts.
