AI Technical Summary

Technical Problem

Existing recycled concrete structures with built-in insulation are not easy to connect quickly when connecting built-in insulation boards and mesh, resulting in insufficient connection strength between the concrete and the built-in insulation layer, which affects the overall structural stability.

Method used

The system employs components such as connecting screws, positioning pressure plates, support cylinders, limit plates, and locking nuts. Through threaded connections and reinforcing rods, it enables rapid connection between the mesh and the built-in insulation board, and increases the connection strength through reinforcing rods and anti-slip grooves.

Benefits of technology

It improves the connection strength between concrete and built-in insulation board, ensuring the overall stability of the structure and adapting to the needs of concrete structures of different thicknesses.
