Abstract
The invention relates to a pattern plate system of an overlapped shear wall. Force bearing bars are arranged on the back of a detachable inner pattern plate of a post pouring shear wall at intervals. The inner pattern plate is connected with an outer pattern plate through a connecting device. The connecting device comprises a reducing screw, an isometric screw and a connecting piece. The connecting piece is fixedly arranged on the force bearing bars through bolts. The isometric screw is provided with a clip. The isometric screw passes through the outer pattern plate and the detachable inner pattern plate sequentially from the outer surface of a secondary keel and is screwed into the connecting piece. The clip on the isometric screw is fixedly arranged on the outer surface of the secondary keel. The reducing screw penetrating through the end part of a previous pouring shear wall piece extends into the connecting piece. According to the pattern plate system of the overlapped shear wall provided by the invention, under the condition that a normal pattern plate is used as the inner pattern plate, the inner pattern plate can be simply installed and disassembled without inner-joint operation. The pattern plate system of the overlapped shear wall provided by the invention has the advantages of simple supporting structure, accurate positioning and the like, and can be widely applied to construction of post pouring shear wall pieces of the overlapped shear wall.
