AI Technical Summary

Technical Problem

In existing construction projects, the pull-out resistance of expansion bolts depends on the friction between the expansion sleeve and the concrete hole wall and the bonding force of high-strength structural adhesive. However, the friction is uneven and the adhesive bonding force decays quickly, causing the anchoring system to fail in the early stage, affecting the long-term stability and waterproof performance of the concrete joint.

Method used

Multiple fastening mechanisms are employed, including components such as a base plate, threaded plate, bolts, and hexagonal columns. Through threaded transmission and bevel gear meshing, the bolts are stably fastened and detachably connected, enhancing the stability of the concrete joint. The fastening mechanism is fixed by a limiting groove and a snap-fit ​​structure to prevent difficulties in bolt recovery.

Benefits of technology

It improves the long-term stability and waterproof performance of concrete joints, avoids the early degradation of high-strength structural adhesives and the increase in construction costs, and ensures the long-lasting effectiveness of the anchoring system.
