Formwork structure between small-spacing shear walls and construction method

Abstract

The invention discloses a formwork supporting structure between small-spacing shear walls and a construction method. According to the structure, a large steel mold and a rib plate are arranged on theouter sides of the shear walls, and plywood and a square wood column are arranged on the inner sides of the shear walls; a plurality of screw holes are formed in the surface of the large steel mold atequal intervals in the horizontal direction and the vertical direction, and the rib plates are arranged at the positions of the screw holes; through-wall screws are connected with the screw holes ina matched mode, and the through-wall screws sequentially penetrate through the square wood column, the plywood, the shear walls, the large steel mold and the rib plates from the inner sides to the outer sides of the shear walls; the through-wall screws are fixed on the inner sides of the shear walls through fixing nuts, and fixed on the outer sides of the shear walls through limiting nuts; butterfly clamps and frame pipes are arranged between the fixing nuts and the square wooden column, one butterfly clamp is arranged on the inner side of each fixing nut, and two frame pipes are arranged in each butterfly clamp and arranged on the two sides of the corresponding through-wall screw respectively. The formwork supporting structure is simple in structure, easy to construct and operate and capable of being used repeatedly, materials are saved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the construction field of concrete shear walls, in particular to a formwork structure and construction method between small-spacing shear walls. Background technique [0002] The support and removal of formwork between shear walls with small spacing has always been a construction problem due to the narrow space between shear walls and the inaccessibility of operators. Usually one of the shear walls is constructed first, and then the other shear wall is constructed with the polyplastic plate as the outer formwork. In this way, it is inevitable that the cross-sectional size of the shear wall is difficult to ensure, which affects the quality of the project and the external formwork cannot be removed, thereby wasting materials. The present invention can effectively solve the above problems. It has the advantages of local materials, easy operation, cost-effectiveness and so on. While ensuring the quality of the project, it also h...
