Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] As shown in Figure 1, the schematic diagram of the shaping mold for the reserved hole in the concrete wall, the shaping mold frame has a rectangular structure and is composed of four templates 1. The templates are made of steel plates, which can improve the rigidity of the mold, and the quality of the formed concrete on the surface is high. Eight reinforcing ribs 4 are welded on the inner side of the template 1, and the reinforcing ribs are also made of steel plates to further enhance the rigidity of the mold and ensure that the mold will not be deformed due to extrusion when pouring concrete. The reinforcing ribs 4 are intermittently arranged on the inner side of the template, and the gaps left in the middle can improve the deformation ability of the mold when it is expanded or tightened. Fastening bases 7 are respectively wel...

Abstract

The present invention discloses one kind of mold used in building construction for setting the reserved holes in concrete wall. The mold includes one mold frame comprising formworks and one inside formwork supporting device. The formwork supporting device includes one middle screw bolt with alternately arranged forward threads and backward threads connected to the upper and lower sides of the mold frame for regulating the mold height, and one four-rod link drive mechanism connected to the right and left sides of the mold frame for regulating the mold width. In addition, the mold frame has also reinforcing ribs and thus enhanced rigidity and certain deforming ability. The setting mold has high rigidity, easy assembling and disassembling, reuseability, low cost and capacity of raising construction efficiency.

Description

technical field [0001] The invention relates to a mold used in building construction, in particular to a mold for shaping a reserved hole in a concrete wall. Background technique [0002] During the building construction process, it is often necessary to reserve some holes on the concrete wall, such as the reserved holes for installing the distribution box after construction. These reserved holes are reserved by using molds when pouring concrete. The existing reserved hole mold is mainly made of bamboo plywood and wooden block nails. When in use, a simple support is taken inside the mold frame, and then concrete is poured. There are some disadvantages in this traditional mold: First, the bamboo plywood and wooden blocks are less rigid and not easy to fix, so it is more difficult to fix the mold. Secondly, due to the low rigidity of the mold, it is easy to shift and deform the mold when pouring concrete, resulting in irregular shapes or deviations in the positions of the res...
