Manufacturing method of steel mesh member used for forming holes of hollow floor slab

Abstract

The invention provides a manufacturing method of a steel mesh member used for forming holes of a hollow floor slab. The manufacturing method includes manufacturing a specially made steel mesh with a mesh board, reinforcing ribs, a connecting board and side reinforcing ribs by punching and drawing a thin steel roll, and pressing bent lines on the steel mesh reinforcing ribs in the vertical direction; cutting a thin sheet into a side panel and a support board in required specification; transporting the steel mesh and the thin sheet to a hollow floor slab construction site to be assembled, bending the steel mesh along the bent lines to form a top panel, a bottom panel and tetrahedrons of two side walls of a hexahedron steel mesh member, wherein the thin sheet comprises a calcium silicate board, a plastic board, a composite board, a plasterboard or a corrugated board; the thin sheet constitutes another two side wallboards and a support board between the top panel and the bottom panel of the steel mesh; the thin sheet used for the side wallboards is disposed in side reinforcing rib grooves of two edges of the steel mesh, the length of the support board is larger than or equal to that of the inner clearance of the steel mesh, and the support board directly supports the top side wallboard; the head and tail ends of the steel mesh are overlapped on the top surface of the steel mesh member and welded by electric welding to form the steel mesh member.

Description

technical field [0001] The invention relates to a cavity component used for non-centering hole forming of a hollow floor, in particular to a manufacturing method of a steel mesh component used for forming a hole in a hollow floor. 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 mes...

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
