Cavity floor system cast through ribbed steel net plate for carving in place

Abstract

The invention provides a cavity floor system cast through a ribbed steel net plate for carving in place. The cavity floor system is composed of a main beam, a ribbed beam, a top flange plate, a bottom flange plate, a column and beam structural platform and the ribbed steel net plate for carving. The column and beam structural platform is a hidden platform or visible platform or conical platform. A steel net body of the ribbed steel net plate for carving is cast in bottom flange plate concrete on site. The ribbed steel net plate for carving is composed of a carving net, a carving end net and a supporting net. The carving net, the carving end net and the supporting net are both made of pure metal materials. The carving net is arranged around the ribbed steel net plate for carving. The steel net body comprises steel plate expansion net holes, a V-type rib and a turning connecting sheet. The expansion net holes in the two sides of the turning connecting sheet are not located in the same direction. The supporting net is a steel net body or reinforcement net body. The supporting net is manufactured to be in an n shape or m shape. The reinforcement net body is formed by the square crossing ends of longitudinal-row reinforcement and transverse-row reinforcement in a coaxial multi-point welding manner. The ribbed steel net plate for carving is used for casting the cavity floor system and directly cast in concrete on the edge of a cavity on site, and the defects existing in an existing cavity floor system are effectively overcome.

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, and solve the problem of the entire ribbed steel mesh. The support nets are all pure mesh metal materials, which are beneficial to the realization of building energy-saving integration and the multi-functional 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 floors, using The unsealed ribbed steel mesh can replace the existing fully sealed hollow filling body or polystyrene foam solid filling body, and the steel mesh filling body supported by various plates will be transformed and upgraded to optimize the existing cast-in-place cavity building The hole-forming technology of the cover overcomes the defect that any filling body in the hole-forming technology of the existing cavity floor cannot work together with the floor to bear the force
