FRP connector is a key component to connect the concrete slabs on both sides of the insulation slab, and its main function is to resist the lifting action between the concrete slabs of the inner and outer leaf walls and the shear force between the walls.The FRP connector consists of two components, FRP connector plate and ABS engineering plastic collar. The FRP connector plate is used to connect the concrete slabs on both sides of the insulation slab, while the ABS engineering plastic collar is used to hold the connector in place during concrete placement.
