AI Technical Summary

Technical Problem

Existing vacuum insulation panels, which are fixed to the wall with anchor rods, are prone to falling off, causing cold and thermal bridging problems, which affect the insulation effect and building safety.

Method used

The anchor rod is fixed to the wall using a fastening connection between an anchor rod and a binding metal plate. The anchor rod is close to the limiting plate. The anchor rod is fixed to the wall using the fastening metal plate. The outer diameter of the end of the anchor rod near the limiting plate is larger than that of the other end, which is a reducing rod. Multiple inclined anti-loosening barbs are evenly provided on the outer wall of the end of the anchor rod away from the limiting plate. The distance between the outer edge of the anti-loosening barb and the central axis of the anchor rod is smaller than the outer diameter of the end of the anchor rod near the limiting plate. A binding metal plate is threaded onto the anchor rod at the end of the anti-loosening barb away from the limiting plate. Multiple semi-circular binding grooves are provided on the outer wall of the binding metal plate. The anchor rod adopts a metal connecting rod with an outer composite high-strength plastic structure.

Benefits of technology

It achieves a firm fixation of the vacuum insulation board, preventing it from falling off, improving the convenience of construction and the reliability of the connection, reducing heat transfer efficiency, solving the problem of cold and thermal bridges, and improving the thermal insulation performance.
