Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] Such as Figure 1-4 As shown, a prefabricated concrete sandwich thermal insulation exterior wall panel connected by W-shaped steel core glass fiber bars has a three-layer structure, which is the inner leaf concrete wall panel, the insulation layer 3, and the outer leaf concrete wall panel. The rib connector 4 connects the three-layer structure into a whole;
[0019] The inner and outer leaf concrete wall panels 1 are poured with ordinary concrete or light aggregate concrete, and the inner and outer leaf concrete wall panels 1 are equipped with steel mesh sheets 2, and the thermal insulation layer 3 is a non-flammable insulation board. The similarities and differences in the thickness of concrete wall panels 1 are divided into two types: center and offset;
[0020] The steel bar core glass fiber bar connector 4 is to wrap the continuous...
