Steel mesh hollow component with supporting points

Abstract

The invention provides a steel mesh hollow component with supporting points. The steel mesh hollow components with the supporting points comprises a ribbed steel mesh, a folding supporting frame, an end cap short mesh, the supporting points and non-woven fabric, wherein the ribbed steel mesh is a rhombic steel mesh and is used as a steel mesh hollow component body. Reinforcing steel sheets are additionally arranged at the two ends of the end cap short mesh, and the length of the reinforcing steel sheets is smaller than the width of the end cap short mesh. The portions, not additionally provided with the reinforcing steel sheets, of the end cap short mesh are exposed out of the four outer corners of the lower bottom of the steel mesh hollow component. Ribs of the exposed end cap short meshform the supporting points at the four corners of the lower bottom of the steel mesh hollow component. The non-woven fabric is wound on the lateral surface of the steel mesh hollow component.

Description

technical field [0001] The invention relates to a system technology of a cast-in-place concrete cavity floor, in particular to a technology of a steel mesh hollow member with supporting points. Background technique [0002] For example, in order to realize the industrial production of the non-core-pulling hole-forming components of the cast-in-place hollow floor, the inventor pioneered the use of steel reticulated materials instead of plate bodies to manufacture the non-core-pulling hole-forming components of the cast-in-place hollow floor. On the basis of the hole-forming components of the original plate body, the invention and application of "a reticulated box-shaped component for forming holes in the cast-in-place hollow floor" ZL201310332173.9 and ZL201510331724.X "a new type of steel-concrete composite cast-in-place hollow floor ", transform and upgrade the existing pouring hollow floor technology, and create conditions for replacement; the application of reticulated bo...

Problems solved by technology

[0003] However, there are still problems to be perfected in the original application of reticulated box-shaped components. The inventor has continuously improved the background technology of cast-in-place hollow floors and invented a double-layer structure composed of ribbed steel mesh body, support body and sealing body. ZL201721318739.2 is a hollow body member with curved surface and network shape; the combined network box-shaped member is improved and the combination of pure steel materials is used to further improve industrialization, and at the same time solve the production combination and use functions, and effectively monitor the concrete collapse If the slump is too large, there will be hidden dangers in the quality of the building

However, due to the control of the concrete slump, its fluidity becomes wrong, and the pipeline of the cast-in-place concrete pump is often blocked.

[0004] Using ribbed steel mesh to make cast-in-situ hollow floor non-core-pulling hole-forming components is a major measure, but due to excessive concrete slump, the concrete mortar will segregate and leak into the reticulated box-shaped component, changing the If the concrete slump according to the design requirements, the concrete mortar does not segregate, and it is the best effect of seeping and not leaking for the reticulated box-shaped components, it will also affect the normal use of construction equipment, resulting in such a situation.
