[0035] The first fast-assembling prefabricated shear wall 3A and the second fast-assembling prefabricated shear wall 3B have the same structure as described above, and the structure of the second fast-assembling prefabricated shear wall 3B will not be described here.

[0036] Although the first fast-assembling prefabricated shear wall 3A and the second fast-assembling prefabricated shear wall 3B are both provided with assembling grooves 32 extending to the upper and lower end faces of the fast-assembling prefabricated shear wall on both sides of the side walls, in the adjacent first fast-assembling prefabricated shear wall 3A and the second fast-assembling prefabricated shear wall 3B, the assembling grooves 32 on both sides of the first fast-assembling prefabricated shear wall 3A extend to the front side wall respectively, and the assembling grooves 32 on both sides of the second fast-assembling prefabricated shear wall 3B extend to the back side wall respectively.
