Suspended mold which is applied to slab and is reserved with holes

Abstract

The invention discloses a hanging formwork applied to a reserved hole in a floor, comprising a left formwork, a right formwork and a supplementary formwork, the left formwork and the right formwork have a tile-shaped fixing plate and a support plate, and the tile-shaped fixing plates of the left formwork and the right formwork Hinged together at one end face, part of the support plate is cut off, and a complete ring can be formed after the mending mold and the support plate are combined; a hinge seat is fixed on the tile-shaped fixed plate, and a rotating plate is set on the hinge seat, and the rotating plate is rotated. The upper end of the plate abuts against the lower surface of the support plate and can support the lower surface of the patching mold; the other end surfaces of the tile-shaped fixed plates of the left mold and the right mold extend outward along a straight line passing through the center of the circle to form a convex plate. There are oblong holes on the top, and one of the oblong holes is connected to the end of the tile-shaped fixing plate with a through hole whose diameter is larger than the width of the oblong hole. The diameter of the hole. Compared with the prior art, the left and right parts of the present invention do not interfere, and the locking is more convenient.

Description

technical field [0001] The invention relates to the technical field of building appliances, in particular to a hanging form applied to reserved holes in floor slabs. Background technique [0002] Water pipes, sewer pipes and other pipes often need to pass through the floor, so holes will be reserved in the floor during the construction process. The current practice is to use iron wire and wooden boards after the water pipes and sewer pipes are installed. Two workers cooperated in the construction, the process was complicated and labor-intensive, and the iron wire was also poured in the concrete during the pouring process. After a long time, the iron wire rusted and easily seeped. [0003] The invention of the publication number CN 204037309 U discloses a kind of hanging formwork frame for the opening of the pipeline, including two halves composed of a semi-cylindrical fixing plate for fastening the pipeline and a support plate perpendicular to the fixing plate for supporting...

AI Technical Summary

Problems solved by technology

However, for the smooth opening of the two support plates, two fan-shaped areas are cut off at the intersection of the support plates, which will result in the inability to effectively support the concrete there, and the other two support plates are fastened with screws. Workers need to carry tools such as wrenches during construction, which is cumbersome and inefficient, and it is not convenient to use in holes near the wall
