Abstract
A laminated plate-type sandwich insulation shear wall with tie bolts, including a prefabricated external wall, a sandwich insulation layer, a cast-in-place concrete layer, a prefabricated internal laminated wall board, and an external wall connector. Several bolts disposed between the external wall and the internal laminated wall board. Each tie bolt consists of cylinder head screw, gland, sleeve, and tie screw casing. During installation, the sandwich insulation wall with the bolts are installed in place in a suspended manner and is temporarily fixed, the tying and connection of reinforcing steel bars is completed, a formwork is supported, concrete is poured, the cylinder head screw is removed after the cast-in-place concrete solidifies and the strength of the cast-in-place concrete increases, and the bolt hole is filled with foamed polyurethane. The sandwich insulation wall solves the problem of mutual destruction of the external and internal walls due to the indoor and outdoor temperatures.
