One end of the threaded rod 3 is inserted into the spiral sleeve 2, and the other end of the spiral sleeve is used to pass through the insulation layer 102 and be fixed in the wall 101. When the threaded rod 3 is completely installed in the insulation wall, a plastering layer 103 is formed on the outside of the insulation layer 102 by plastering. The spiral sleeve 2 and the tail plate 1 are both made of corrosion-resistant metal, and the threaded rod 3 is made of FRP material, so that the corrosion resistance of the connector can be improved to extend the service life of the connector, thereby enabling the insulation wall to function normally as much as possible.

In this embodiment, the threaded rod 3 is set to one of epoxy resin, vinyl resin, glass fiber, carbon fiber or basalt fiber, and is formed by pultrusion and winding. The front end of the threaded rod 3 is set to a tip so that the threaded rod 3 can be drilled into the insulation wall, and the convex and concave of the spiral portion on the threaded rod 3 can increase the anchoring force with the concrete.
[0031] The spiral sleeve 2 is cylindrical in shape as a whole, and the length of the spiral sleeve 2 is smaller than the length of the threaded rod 3. When the connector is installed on the insulation wall, the spiral sleeve 2 is located in the insulation layer 102. The outer side of the spiral sleeve 2 is provided with a spiral groove 21 along its length direction, and the inner side of the spiral sleeve 2 is provided with a spiral inner cavity, and the thread of the threaded rod 3 can be arranged in the spiral inner cavity, so that the threaded rod 3 can be arranged inside the spiral sleeve 2.
[0032] The tail plate 1 is in the shape of a circular plate, and the length direction of the tail plate 1 is perpendicular to the length direction of the threaded rod 3, and the center of the tail plate 1 is located on the axis of the threaded rod 3. A plurality of penetration openings 11 are provided on the tail plate 1. In this embodiment, the penetration openings 11 are arranged in two shapes, namely, a first penetration hole 111 which is an arc-shaped oblong as a whole and a second penetration hole 112 which is a circle as a whole.
