Reserved electricity box hole mould and using method thereof

Abstract

The invention provides a reserved electricity box hole mould. The reserved electricity box hole mould comprises an upper plane frame, a lower plane frame and vertical frames. Pieces of connecting angle steel are arranged at the upper side edge and the lower side edge of each vertical frame, and rubber sandwich cushion blocks are arranged between the connecting angle steel and the plane frames; theconnecting angle steel is fixedly connected with the upper plane frame and the lower plane frame through bolts; and rubber plates covering the periphery of the outer surface of the frames are arranged on the outer side of the mould. A method for constructing a hole through the reserved electricity box hole mould comprises the steps that the mould assembled into a whole is placed at the designatedposition of a wall, the interior of the mould is connected with a steel platform through high-strength magnets, and pre-embedded line pipes are mounted; after the prefabricated wall reaches the mould-dismantling strength, fixing bolts are taken down; then, rubber sandwiches are dismantled, so that mould-dismantling gaps are formed in the upper sides and the lower sides of the vertical frames, andthe vertical frames are knocked lightly to fall off; the plane frames are dismantled in the direction of the line pipes; and finally, the peripheral rubber plates are removed. The mould is manufactured by combining steel members and rubber materials, the mould can be integrally dismantled after the wall is fixedly shaped, and the mould can be used repeatedly.

Description

technical field [0001] The invention belongs to the fabrication and construction technology of prefabricated walls, in particular to a mold used for construction of electric box holes reserved for walls. Background technique [0002] In the process of prefabricating walls, some walls need to reserve openings for electric boxes. Because the electric boxes are connected to wire pipes, the molds for the reserved openings need to open holes so that wire pipes can extend into and fix the wire pipes. And because the size of the opening is generally 400×500mm, it is difficult to dismantle the ordinary split steel mold because the operating space is too small, so foam boards such as polystyrene boards are used as the mold for the opening of the electric box, which has the advantages of strong flexibility and easy installation and disassembly The disadvantage is that the waste of resources is serious, and the foam board can only be removed if it is damaged, and the foam board cannot ...

Problems solved by technology

[0003] In order to solve the disadvantage of using polystyrene board as the material waste of the mold in the electric box hole, the present invention provides a steel and rubber combined mold, which can be reused while meeting the requirements of demoulding
