During construction of the shear wall, the wall body 1 is transported to a construction site, and then the wall body 1 is lifted above the connecting seats 2 through lifting equipment, so that the section steel columns 3 are aligned to the insertion grooves 21. Slowly laying down the wall body 1, enabling the section steel column 3 to be inserted into the insertion groove 21, enabling the two lower baffles 5 to be inserted into the two upper baffles 4 to form a pouring space 6 in a matched mode, simultaneously driving the driving column 51 through the connecting column 11 in the laying down process of the wall body 1, enabling the abutting degree between the lower baffles 5 and the upper baffles 4 to be improved, enabling the supporting column 13 to turn downwards, until the supporting column 13 abuts against the top of the supporting plate 26, enabling the wall body 1 to be in a preliminary fixed state, finally pouring concrete from the pouring hole 31, blocking the pouring hole 31 and the overflowing hole 32 until the concrete overflows from the overflowing hole 32, then smearing the gaps between the wall body 1 and the floor slab with cement, and concealing the section steel column 3, the upper baffles 4 and the lower baffles 5. The whole process is simple, the wall body 1 can be produced in advance, the wall body 1 and floors only need to be connected during construction, welding does not need to be used in the connection process, and the construction time of the stiff concrete shear wall can be greatly shortened.
The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
