Concrete cavity forming mold and use method thereof

Abstract

The invention discloses a concrete cavity forming mold. The mold comprises a telescopic skeleton, an elastic wrapping layer and multiple supporting plates, the supporting plates are arranged around the outer side of the telescopic skeleton, the telescopic skeleton is connected with the supporting plates, the elastic wrapping layer is mounted on the outer sides of the supporting plates, and a use method of the mold comprises the steps of S1, mold filling, wherein the telescopic framework drives the supporting plates to shrink, the elastic wrapping layer is mounted on the outer sides of the supporting plates, the telescopic skeleton drives the supporting plates to extend until the size of the outer contour of the wrapping layer is consistent with a concrete cavity required to be formed, andfinally, the mold is filled in the position of a cavity; S2, concrete pouring; and S3, mold stripping, wherein during mold stripping, the telescopic framework drives the supporting plates to shrink, the elastic wrapping layer shrinks to be separated from the concrete cavity, and the mold is taken out. The mold has the advantages that the cavity structure does not need to be changed, the mold is suitable for concrete cavities in multiple section shapes, long-term use is stable, and reliability is achieved.

Description

technical field [0001] The invention relates to a concrete mold and a method for using the same, in particular to a mold for forming a concrete cavity and a method for using the same. Background technique [0002] At present, there are three main forms of common concrete cavity forming molds: one is the integral cavity mold (abbreviation of the cavity forming mold, the same below), the slope is set along the depth direction of the cavity, and the demoulding is pulled out by the slope. Although the design and production of the cavity mold is relatively simple, there are disadvantages such as changing the structural shape of the cavity, large demoulding force and difficult to guarantee the demoulding quality, and the use is limited; the second is to make multiple loose-assembled cavity molds, This method has a large number of cavity molds, a large amount of assembly and disassembly work, and it is difficult to design, install and dismantle when the cavity cross-sectional area ...

[0002] At present, there are three main forms of common concrete cavity forming molds: one is the integral cavity mold (abbreviation of the cavity forming mold, the same below), the slope is set along the depth direction of the cavity, and the demoulding is pulled out by the slope. Although the design and production of the cavity mold is relatively simple, there are disadvantages such as changing the structural shape of the cavity, large demoulding force and difficult to guarantee the demoulding quality, and the use is limited; the second is to make multiple loose-assembled cavity molds, This method has a large number of cavity molds, a large amount of assembly and disassembly work, and it is difficult to design, install and dismantle when the cavity cross-sectional area is small and the depth is large, and it is difficult to apply; the third is to make multiple hinged cavity molds. Although the mold closing process is relatively simple, the structure of the cavity mold is complex, and it is easy to form a staggered platform between the panels, the joints of the panels are easy to turn and leak, and it is difficult to clean the gap between the panels, and the cavity has a small cross-sectional area and a large depth. In the case of the same, there are also difficulties in design, installation and removal
