Concrete disintegration resisting steel mesh hollow chamber floor system

Abstract

The invention provides a concrete disintegration resisting steel mesh hollow chamber floor system. The concrete disintegration resisting steel mesh hollow chamber floor system consists of ribbed beams, a nonwoven fabric intertwined arc-shaped steel mesh hollow component, an arc-provided top flange plate and a cast-in-place bottom flange sheet; the ribbed beams include longitudinal ribbed beams andhorizontal ribbed beams; the arc-shaped steel mesh hollow component comprises a ribbed steel mesh, overlapped supporting frames, a choke plug short mesh and a nonwoven fabric; the overlapped supporting frames inside the arc-shaped steel mesh hollow component are divided into a wide group and a narrow group; the narrow group is overlapped inside the wide group to form arc-shaped overlapped supporting frames; the nonwoven fabric is at least intertwined on four side surfaces of the steel mesh hollow component; and the top flange plate forms an arc shape matched with the upper surface of the arc-shaped steel mesh hollow component.

Description

technical field [0001] The invention relates to a cast-in-place concrete cavity floor system technology, in particular to a steel mesh hollow cavity floor technology for resisting concrete segregation. 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 reticu...

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
