Hollow floor using steel mesh and plate combination for hole forming

Abstract

A hollow floor using steel mesh and plate combination for hole forming comprises columns, beams, flange plates, and a cavity component formed by steel meshes and thin plates, wherein a solid part column cap larger than 500mm is disposed at the outer edge of each column; the beams are reinforced concrete beams or steel reinforced concrete combined beams; the flange plates are I-shaped section plates or T-shaped section plates; the cavity component is formed by the steel meshes and the thin plates which acts on each other; the steel meshes form the overall forming tetrahedron of the top plate, the bottom plate and two lateral walls of the hexahedron cavity component; the head and tail ends of the steel meshes overlap on one optional face of the tetrahedron; the thin plates include calcium silicate plates, plastic plates, composite plates, gypsum plates or corrugated plates; the thin plates form the other two lateral wall plates of the cavity component and the support plates between the top plate and the bottom plate of the cavity component; the two lateral wall plates formed by the thin plates are placed in edge reinforcing rib grooves at two edges of the steel meshes.

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 plate body 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 applied ...

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 thin plate to become a cavity component for the hole-forming of the hollow floor, and the steel mesh becomes a hollow The top surface, bottom surface and two side walls of the cavity member; the thin plate can be made of waste recycling, which saves energy and reduces costs, and becomes the support body for the two sides of the two ends of the plugged cavity component and the inner wall of the steel mesh. Thin plates are placed in the grooves of the edge ribs to stabilize the structural strength of the steel mesh; the interaction between the steel mesh and the thin plates can improve the overall technical level of the cavity components, effectively solving the problem of vertical anti-floating, The surface of the cavity component needs to be isolated due to the horizontal displacement and the poor compatibility between the steel bar of the floor and the cavity component, and the defects of the bottom pad and the cavity component are easy to be damaged; in particular, the internal support of the cavity component and the sealing at both ends are solved When polyphenylene blocks are used as organic objects, the fire resistance level of special functional buildings is limited, and the density and bulk density of polyphenylene blocks need to be increased to increase the pressure capacity to support the construction load borne by the inner space of the steel mesh, and the polyphenylene blocks occupy the loading space during transportation. Defects such as increased cost, polyphenylene blocks must be made of standard expandable plastic particles, and waste cannot be recycled
