The invention discloses a shear wall reinforcement structure, which comprises two concrete wall panels, the two concrete wall panels are arranged in parallel, one end of the two concrete wall panels is connected to an inner filling steel plate wall, and the inner filling steel plate wall Clamping parts are installed on the outside, and the clamping parts are connected with the inner filling steel plate wall through the clamping structure. There is a concrete wall between the two concrete wall panels, and one end of the concrete wall is fixed on the inner filling steel plate wall. There is a frame, one end of the frame is fixed on the inner side of the concrete wall, the other end is connected with a steel structure column, there are two steel structure columns, and a partition is installed on the top of the two steel structure columns. The shear wall reinforcement structure is convenient in construction, firm in structure, free to adjust and lock, can effectively ensure the cross-sectional size, flatness and verticality of the shear wall, can effectively improve the bearing level of the steel structure column, and plays a role of reinforcement, avoiding In order to avoid the phenomenon of grout leakage or mold explosion caused by fracture during pouring shear walls.
