A cast-in-place folded reticular hollow floor mandrel

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, and in particular relates to a cast-in-place foldable reticular hollow floor mandrel. Background technique [0002] The hollow floor is a kind of cast-in-place reinforced concrete hollow floor; it is also called the cast-in-place beamless hollow floor, which is a hollow beamless floor that is cast-in-place after the mandrel product is installed. The hollow floor includes steel bars, concrete, and a mandrel, and the mandrel is embedded between the reinforced concrete upper rib beam and the lower rib beam. [0003] At present, in the technical field of cast-in-place reinforced concrete hollow floors, a fully sealed filling member is usually used to form a hollow floor, such as the ZL98231113.3 concrete thin-walled cylindrical member declared by the inventor, which is made into a sealed cylindrical filling body. In order to realize the cast-in-place hollow floor, a tubular hollow filling body is provide...

AI Technical Summary

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 transportation, and at the same time, the existing hole-forming technology of cast-in-place hollow floors is optimized, which overcomes the need for isolation and pads caused by vertical anti-floating, horizontal displacement, and poor compatibility of existing hollow floor hole-forming technologies , product damage, heavy quality, troublesome construction and other defects
