Cavity floor with hollow ribbed steel mesh

Abstract

The invention provides a cavity floor with a hollow ribbed steel mesh. The cavity floor with the hollow ribbed steel mesh comprises a main beam, a ribbed beam, an upper flange slab, a lower flange slab, a column-beam structure platform and a hollow ribbed steel mesh, wherein the column-beam structure platform is a hidden platform or an apparent platform or a conical platform; a steel mesh body with the hollow ribbed steel mesh is cast in situ in concrete of the lower flange slab; the hollow ribbed steel mesh comprises a hollow mesh, a hollow end mesh and a support mesh; the hollow mesh, the hollow end mesh and the support mesh are made of pure metal materials; the hollow mesh forms the periphery of the hollow ribbed steel mesh; the steel mesh body comprises steel slab expansion mesh holes, a V-shaped rib and a steering connection sheet; the expansion mesh holes on two sides of the steering connection sheet are located in the same direction; the support mesh is a steel mesh body or a steel bar mesh body. Through the cavity floor with the hollow ribbed steel mesh, the cavity floor is cast by the hollow ribbed steel mesh; concrete mortar directly wraps the hollow ribbed steel mesh, participates in stressing and resisting crack together; the defect of the existing hollow floor technology can be effectively solved.

Description

technical field [0001] The invention relates to a technology of a cast-in-place reinforced concrete cavity floor, in particular to a technology of a cavity floor cast-in-place with a ribbed steel mesh. Background technique [0002] At present, in the field of cast-in-place reinforced concrete hollow floor technology, a fully sealed filling body component is usually used to form a hollow floor, such as the ZL98231113.3 concrete thin-walled cylinder component declared by the inventor, which is made into a sealed cylindrical filling body. In order to realize the cast-in-place hollow floor, a tubular hollow filling body is provided, which solves the technical problem of non-centering hole formation in the cast-in-place hollow floor. However, due to the sealed tubular hollow filling body, there are defects such as difficult fixing, high buoyancy, high density and heavy weight, inconvenient production, transportation and on-site construction, low evacuation rate, and inability to ...

Problems solved by technology

[0006] The object of the present invention is a cavity floor that is cast-in-place with ribbed steel mesh, fully utilizes the film effect and surface tension of cast-in-place concrete, and casts on the outer edge of the ribbed steel mesh and the end mesh. Concrete penetrates into the inner surface of the steel mesh body, forming a convex cement mortar pile group to hold the steel mesh body together to resist cracking and noise reduction; the development and production efficiency is high, the composite with concrete is good, and isolation and fixation are eliminated, and anti-corrosion is eliminated. Cracked steel wire mesh, improve quality, reduce construction auxiliary costs, convenient transportation and construction, no buoyancy, inhibit the generation of building cracks, meet design requirements, ensure project quality, solve the problem of mesh and end mesh with ribbed steel mesh The support net and the supporting net are all pure mesh metal materials, which are beneficial to the realization of building energy-saving integration and the multi-function ribbed steel mesh hollowing necessary for the floor; the ribbed steel mesh hollowing is used to realize the new technology of cast-in-place cavity floor, Use unsealed ribbed steel mesh to replace the existing fully sealed hollow filling body or polystyrene foam solid filling body, and upgrade the steel mesh filling body supported by various plates to optimize the existing cast-in-place cavity The floor hole forming technology overcomes the defect that any filling body in the existing cavity floor hole forming technology cannot work together with the floor to bear the force
