The invention provides a formwork combination. The formwork combination comprises a first formwork, a second formwork and an opposite-pull assembly, and the first formwork and the second formwork arearranged at intervals. The opposite-pull assembly comprises a screw, a nut and at least one blocking piece, the screw comprises a first end part and a second end part opposite to the first end part, the nut is used for sleeving the first end part, a slot is formed in the second end part, the blocking pieces are rotatably contained in the slot, and the blocking pieces comprise first positions and second positions. When the blocking pieces are located at the first positions, the blocking pieces are located in the slot, so that the second end penetrates through the first formwork and the second formwork. When the blocking pieces are located at the second positions, parts of the blocking pieces are located outside the slot, the blocking pieces are used for abutting against the surface of the second formwork, and the nut is used for abutting against the surface of the first formwork. The formwork combination can realize high mounting efficiency, saves the use amount of the nuts, and can save the material cost.
Description
technical field [0001] The invention relates to a template combination. Background technique [0002] For the aluminum formwork of the screw system, the wall-through screw provides the necessary lateral tensile force for the aluminum formwork. The wall-through screw mainly includes a screw body and two nuts matching the screw body. thread, the nut part is provided with an internal thread that cooperates with the external thread. When in use, the screw body passes through two aluminum templates that are oppositely arranged, and the two nut parts are respectively inserted from both ends of the screw body until they reach the Lean against the aluminum formwork. [0003] In the prior art, the external thread covers the screw body in the axial direction, and two nuts are needed to lock the opposite aluminum formwork, resulting in high production cost and low installation efficiency. Contents of the invention [0004] The object of the present invention is to provide a formwor...
