Hollow floor using steel mesh and thin plate combination for hole forming

Abstract

A hollow floor using steel mesh and thin plate combination for hole forming comprises columns, beams, flange plates, and a cavity component formed by steel meshes and thin plates, wherein 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; in-situ concrete pouring is performed on the columns, the beams and the flange plates.

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 thin 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 applied ...
