In the installation process of the traditional prefabricated wall, the two walls are connected by adopting the filling sleeve in the longitudinal direction, and the mechanical property of the prefabricated wall is not greatly different from that of a cast-in-place wall. However, the two walls are welded by embedded parts in the transverse direction, the connection rigidity is weak, and compared with a cast-in-place wall, the integrity of the assembled wall is poor. And a large intersection seam is easily generated at the transverse junction of the two walls, and the current common method is to directly and simply fill the wall seam and then carry out surface sealing treatment. However, in the method, a cold and hot bridge is easily formed, the heat preservation and insulation effect of the building is weakened, the energy consumption and vibration reduction capability of the building is insufficient, and the wall is easy to crack under transverse vibration. Therefore, the wall connecting device which is reasonable in design and obvious in energy consumption effect is developed, and the safety, the stability and the shock resistance of the fabricated building can be improved.
