Abstract

The invention relates to the technical field of fabricated concrete, in particular to a cavity forming mold, a using method and a self-checking method. The cavity forming mold comprises an inner mold, the inner mold comprises a base and lifting assemblies arranged on the base in rows, each lifting assembly comprises a fixing part and a top support, the inner mold further comprises a first magnetic part and a second magnetic part, the first magnetic parts and the second magnetic parts are arranged on the fixing parts and the top supports respectively, and the first magnetic parts and / or the second magnetic parts have / has variable magnetism; the top support is arranged on the fixed part in a lifting manner through variable magnetism; and the outer cover covers the periphery of the inner mold and is suitable for isolating concrete. According to the cavity forming mold, forming of a prefabricated part cavity is achieved through lifting of the jacking support on the fixing part, operation is easy, demolding is convenient, cyclic utilization can be achieved, the manufacturing cost is low, in addition, the outer cover can isolate the inner mold from external concrete, the wrapping protection effect is achieved, the effect of a steel net film can be replaced, and repeated utilization can be achieved.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete, in particular to a cavity forming mold, a use method and a self-checking method. Background technique [0002] As a typical prefabricated component, prefabricated concrete cavity wall is widely used in prefabricated concrete structures. The structure of the cavity wall includes two concrete blades and a formed steel skeleton between the two concrete blades. cavity, eventually forming a cavity wall. [0003] At this stage, the inner cavity of the cavity wall is generally filled with soft core molds such as rubber airbags. After the concrete is cured and solidified, the airbag mandrel is drawn out, or the filling form of "airbag + steel mesh" is used, and the airbag is a steel mesh film. support. [0004] However, the existing molding structure has the following defects: easy to scratch and leak air, requiring air pressure monitoring and control; difficult to demold, inconvenient t...
