Folding netlike mandrel for cast-in-place hollow floor

Abstract

The invention publishes a folding netlike mandrel for a cast-in-place hollow floor, and belongs to the field of buildings. The folding netlike mandrel for the cast-in-place hollow floor is a hexahedral netlike box body structure consisting of a folding movable net body, a fixed net body and skeletons, wherein a lifting inner supporting mechanism is arranged in the netlike box body structure; a telescopic outer supporting mechanism is arranged outside the netlike box body structure. Aiming at the above problems, the invention is intended to provide the folding netlike mandrel for the cast-in-place hollow floor; a novel netlike folding mandrel is adopted; the problems that an existing mandrel is large in floor space, is difficult to move, is inconvenient to transport, and the like, are solved; the folding netlike mandrel for the cast-in-place hollow floor is uneasy to damage in a carrying process; meanwhile, an existing pore-forming technique of the cast-in-place hollow floor is optimized; the defects which exist in the existing pore-forming technique of a hollow floor and that the separation and the block padding are needed, a product is damaged, the quality is poor, the construction is fussy, and the like, which are caused by vertical anti-floating, a horizontal displacement and poor compatibility, are overcome.

Description

technical field [0001] The invention belongs to the field of construction, in particular to a cast-in-situ folding mesh hollow floor core mould. Background technique [0002] The hollow floor is a cast-in-place reinforced concrete hollow floor; also called the cast-in-place beamless hollow floor, the hollow beamless floor is cast in place after installing the core mold product. The hollow floor cover includes steel bars, concrete and mandrels, and the mandrels are embedded between the upper rib beam and the lower rib beam of the reinforced concrete. [0003] At present, in the technical field of cast-in-place reinforced concrete hollow floors, the hollow floors are usually cast with fully-sealed filler components, such as the ZL98231113.3 concrete thin-walled cylindrical components reported by the inventor, which are made into sealed cylindrical fillers. In order to realize the cast-in-place hollow floor, a tubular hollow filling body is provided, which solves the technolog...

Problems solved by technology

[0007] The purpose of the present invention is to address the above problems, to provide a cast-in-place foldable reticular hollow floor mandrel, adopting a new reticular foldable mandrel, which solves the problem that the existing mandrel occupies a large area, is difficult to move, and is inconvenient to transport. Problem: It is not easy to be damaged during the transportation process, and at the same time, the existing hole-forming technology of the cast-in-place hollow floor is optimized, which overcomes the need for isolation and pads caused by vertical anti-floating, horizontal displacement, and poor compatibility of the existing hollow floor hole-forming technology , product damage, heavy quality, troublesome construction and other defects
