Hollow slab floor adopting steel nets and plastic plates for combined hole forming

Abstract

The invention provides a hollow slab floor adopting steel nets and plastic plates for combined hole forming. The hollow slab floor consists of posts, beams, flange plates and cavity components formed by the steel nets and the plastic plates, wherein the beams are reinforced concrete beams or sectional steel concrete combined beam, the flange plates are I-shaped cross section plates or T-shaped cross section plates, the cavity components formed by the steel nets and the plastic plates are formed by the steel nets and the plastic plates through mutual action, the steel nets form tetrahedrons of the top surface plates, the bottom surface plates and the two side walls of the hexahedron cavity components, the head and tail ends of the steel nets are overlapped at any one side of the tetrahedrons, the plastic plates form the other two side wall plates of the steel net cavity components and support plates between the top surface plates and the bottom surface plates of the cavity components, and the plastic plates are arranged in edge reinforcing rib grooves formed in the two edges of the steel nets.

Description

technical field [0001] The invention relates to a hollow floor which uses a cavity member to form a hole without centering, in particular to a hollow floor which uses a steel mesh and a plastic plate to form a hole. Background technique [0002] At present, in the technical field of cast-in-place reinforced concrete hollow floors, fully sealed or lightweight solid cavity components are usually used to form holes and form hollow floors, such as ZL200410082381.9 "a hollow small ribbed building" declared by the inventor "cover", using fully sealed thin-walled box cavity components buried in the small ribbed floor to form a "T-shaped" force section hollow layer, which solves the problem of "T-shaped" force section small dense rib hollow floor Problem with slippery roof. However, there is no designed stress reinforcement between the bottom of the fully-sealed thin-walled box cavity member and the hollow floor formwork, and a layer of crack-resistant steel wire mesh must be appli...

Problems solved by technology

[0007] The purpose of the present invention is to ensure the hole-forming specifications of the hollow floor, and then make full use of the hollow floor to realize the integration of building energy saving; organically combine the advantages of the steel mesh and the performance of the plastic plate to become a cavity component for the hole forming of the hollow floor, and the steel mesh becomes The top surface, bottom surface and two side walls of the cavity component; the plastic plate can be made of waste recycling, which not only saves energy, reduces costs, but also becomes the support for the two sides of the two ends of the cavity component and the inner wall of the steel mesh. The plastic plate is placed in the groove of the edge rib on the edge of the steel mesh to stabilize the structural strength of the steel mesh; the interaction between the steel mesh and the plastic plate can improve the overall technical level of the cavity component, and effectively solve the problem of the hole forming technology of the existing hollow floor. Vertical anti-floating, horizontal displacement, and poor compatibility between the steel bars of the floor and the cavity components cause the surface of the cavity components to be isolated and the bottom pads, and the defects of the cavity components are easy to be damaged; especially solve the internal support and When polyphenylene blocks are used as organic objects for both ends of the block, the fire resistance level of special functional buildings is limited, and the density and bulk density of polystyrene blocks need to be increased to improve the compression capacity to support the construction load borne by the inner space of the steel mesh. Polyphenylene blocks during transportation Occupying the loading space and increasing the cost, the polyphenylene block must be made of standard expandable plastic particles and cannot be recycled from waste, etc.
