1. the steel bar truss is used for the double-sided superposed shear wall, in the manufacturing process of the shear wall, steel bars are arranged, a large amount of time is usually spent on spot welding of the steel bars, the workload is overlarge, the electric welding precision is not high, the mechanization degree is poor, and the steel cost is increased linearly. The manufacturing efficiency of the prefabricated part cannot be ensured, and the manufacturing cost of the part is increased;

2. the prefabricated composite shear wall is used in high floors, if the thickness of the shear wall is large, the cavity between the prefabricated composite wall boards is filled with too thick concrete, the problems of uneven stress, overlarge self weight and the like can be caused, and how to construct the prefabricated composite shear wall with multiple rows of reinforcing bars does not have a satisfactory scheme, and meanwhile, great difficulty is caused to hoisting in the prior art, the construction difficulty is large, and the construction efficiency is reduced.

In a word, when facing to the engineering project that has great span and height, there is the preparation cycle long, and work load is big, and the cost of manufacture is high, and structural performance can't guarantee, can't compromise the problem such as construction degree of difficulty and efficiency of construction simultaneously to current prefabricated two-sided superimposed shear wall
