Cast-in-place hollow floor system using steel mesh and inflatable tube combination box for pore-forming

Abstract

The invention provides a cast-in-place hollow floor system using a steel mesh and inflatable tube combination box for pore-forming. The cast-in-place hollow floor system is composed of a main beam, a ribbed beam, an upper flange plate, a lower flange plate and the steel mesh and inflatable tube combination box. The main beam is a reinforced concrete combination beam or a fashioned iron beam. The steel mesh and inflatable tube combination box is formed by interacting a steel mesh and inflatable tubes. The steel mesh forms a box top, a box bottom and two side walls of the combination box. According to the inflatable tubes, plastic is made into air storage tubular bodies or polystyrene blocks to form the other two side walls of the steel mesh and inflatable tube combination box and the height of the inner space of the supporting box top and the box bottom. An existing full-sealed hollow filling body and solid filling body are replaced by an unsealed mesh-like box-shaped member for the pore-forming technology of the cast-in-place hollow floor system, and the combination of the steel mesh and the inflatable tubes is adopted. In this way, the problems of plugging of the other two side walls of the steel mesh box and the height of the inner space between the supporting box top and the box bottom are effectively solved, and construction of the cast-in-place hollow floor system is facilitated.

Description

technical field [0001] The invention relates to a cast-in-place hollow floor with holes formed by non-centering filler components, in particular to a cast-in-place hollow floor with holes formed by a combined box body of a steel mesh and an inflatable tube. Background technique [0002] At present, in the technical field of cast-in-place reinforced concrete hollow floors, fully-sealed filler components are usually used to form holes and form hollow floors, such as ZL200410082381.9 "a hollow small ribbed floor" declared by the inventor, which uses thin-walled The box filling body is buried in the small ribbed floor to form a hollow layer with a "T-shaped" stress section, which solves the problem of smooth roof of the "T-shaped" stressed section small ribbed hollow floor, and has been widely used. However, there is no designed stress reinforcement between the bottom of the thin-walled box filling body and the hollow floor formwork, and a layer of crack-resistant steel wire mes...

Problems solved by technology

[0006] The purpose of the present invention is to organically combine the advantages of the steel mesh with the performance of the inflatable tube to provide a brand-new hole-forming technology for the cast-in-place hollow floor. It is not only a part of the box body, but also the support body of the steel mesh. The two work together to improve the overall technical level of the filling body, and effectively solve the problems of vertical anti-floating, horizontal displacement, and reinforcement of the floor in the existing hollow floor hole forming technology. Isolation and pads caused by poor compatibility between the concrete and the composite box, damage, a large number of supports inside the box and box sealing are troublesome, the surface needs to be isolated, the filling body does not have the anti-cracking function of the floor, and there are still large buoyancy, Low degree of industrialization, inconvenient transportation and installation, to achieve a cast-in-place hollow floor with guaranteed construction quality
