AI Technical Summary

Technical Problem

In existing construction projects, the rust prevention treatment of the ends of steel bars is inefficient, and traditional sheaths cannot be reused, which affects construction efficiency and component safety performance.

Method used

It adopts a combination structure of sheath and end cap, with a fixed connecting spring on the end cap. The spring has a closing force, which, together with the reinforcing ribs and binding parts, enables the quick sealing of the end of the rebar. The end cap can be replaced according to the size of the rebar to improve the reuse rate.

Benefits of technology

It improves the efficiency and reusability of rust prevention treatment at the ends of reinforcing bars, enhances the installation stability and waterproof effect of the sheath, extends the service life of the spring clips, and ensures the safety performance of the components.
