FRP insulation connector is applicable to the connection and force transfer between the inner leaf wall insulation layer and the outer leaf wall of the prefabricated sandwich insulation wall in the fabricated concrete structure. It not only has reasonable stress and reliable connection to ensure the structural safety of the prefabricated sandwich insulation wall, but also can realize the coordinated deformation of the insulation connector and the wall concrete and effectively prevent the cracking or warping of the prefabricated sandwich insulation wall.
