Method and mold for molding precast concrete hollow wall component for concrete-filled laminating

Abstract

The invention relates to a method and a mold for molding a precast concrete hollow wall component for concrete-filled laminating and belongs to buildings. According to the method, a screw rod mold is placed into a precast concrete hollow wall, and the screw rod mold is screwed out before concretes are subjected to permanent set, so that hollow holes are formed in the precast concrete hollow wall, and shear slip resisting keyslots are formed on the inner walls of the holes, therefore the precast concrete hollow wall component can enable new and old concretes to be combined into a whole after being subjected to concrete cast-in-place laminating during a prefabricated concrete structure engineering; and the mold is used in a process of forming the hollow holes with the shear slip resisting keyslots in the concretes and can be used for manually or mechanically screwing out screw caps conveniently. The mold has the advantages of light weight and convenience in transportation and hoisting, and can be used for obviously improving the construction quality and work efficiency of prefabricated concrete structure buildings and lowering the building construction cost.

Description

technical field [0001] The present invention relates to building structures, in particular to building construction engineering structures, in particular to a prefabricated molding method and a mold for a prefabricated concrete structure of a building building, especially to a method for forming a prefabricated concrete hollow wall component used for pouring cores and lamination. mold. Background technique [0002] The application number is 01212935.6, and the patent titled "reinforced concrete split type hollow shear wall panel" discloses a reinforced concrete split type hollow shear wall panel. The rib units are separated by templates to form vertical joints; a cylindrical inner mold is placed in the middle of the shear wall panels to form vertical holes in the wall panels. The reinforced concrete split hollow shear wall panel is only used in the reinforced concrete hollow shear wall structure. Since the isolation layer is formed by the construction method of the built-in...

Problems solved by technology

[0006] The purpose of the present invention is to provide a molding method and mold for prefabricated concrete hollow wall components used for core filling and lamination, so as to solve the problem that in the existing hollow wall panel hole forming methods, some hollow hole inner walls use independent inner molds, and there is isolation. After pouring the laminated concrete, the old and new concrete cannot be integrated into one; in some cases, although the hole is formed with a mold, the anti-shear slip keyway cannot be made on the inner wall of the hole, so that the old and new concrete can be combined after pouring the laminated concrete. The performance of complete integration cannot be guaranteed; and solve the technical problem that the old and new concrete can be integrated after pouring the laminated concrete in the actual engineering application process of the precast concrete hollow wall
