It has the advantages of fast construction speed, good project quality, low labor consumption, energy saving and environmental protection.

[0003] my country's concrete module technology is mostly used in shear wall structures. According to the type of vertical components, it can be divided into three types: membrane shell type, fully prefabricated type and composite type. The composite type has the characteristics of light module weight and small impact on the usable area, and has broad application prospects. The existing technology uses single-sided composite shear wall panel prefabricated components, that is, one side is a blade and the other side uses an insulation layer as a blade.
