AI Technical Summary

Technical Problem

The existing variable diameter steel cages, after being lowered to the designated position, have poor overall strength and stability, making it difficult to effectively cope with the building's own weight, strong winds, earthquakes, and other loads. As a result, the structural bearing capacity is not fully utilized, posing safety hazards.

Method used

The steel cage structure, consisting of a concrete foundation and threaded steel bars, is combined with a base slab, bent-up bars, and spiral stirrups. The anti-corrosion layer of the threaded steel bars and thermoplastic sleeves enhance the structural stability. Water-swellable sealing strips are used to prevent moisture intrusion, improving waterproof performance and durability.

Benefits of technology

It enhances the overall strength and stability of the steel cage, enabling it to better withstand various loads, improves the compressive strength and deformation capacity of the structure, extends its service life, reduces the risk of steel corrosion, and ensures building safety.
