Cavity floor with pores being formed through steel net body

Abstract

The present invention provides a cavity floor slab with holes formed by a steel mesh body. The cavity floor slab is composed of a main girder, a rib beam, concrete and a steel mesh body; the reinforcement in the middle of the girder is less than the reinforcement at both ends of the girder; The concrete slump is less than 200mm; the steel mesh body is composed of steel mesh and foamed cement blocks; the steel mesh is expanded steel mesh or steel plate punching mesh; the foamed cement blocks are supported foamed cement blocks and plugging foamed cement blocks; the height of the foamed cement blocks matches the height of the inner space of the steel mesh; there is at least one supporting foamed cement block and two blocking foamed cement blocks in the steel mesh body; the void The cavity floor can be used as a solar air supply pipe and a fire prevention and smoke exhaust pipe to realize the multi-functional application of the cavity floor.

Description

technical field [0001] The invention relates to a building floor technology, in particular to a cavity floor technology using a steel mesh body to form holes. Background technique [0002] For example, the ZL98231113.3 concrete thin-walled cylindrical member declared by the inventor is made into a sealed cylindrical filling body, which provides a tubular hollow filling body for the realization of the cast-in-place hollow floor, and solves the problem of non-extraction of the cast-in-place hollow floor. But there are problems of one-way force and low evacuation rate; in order to solve this defect, such as ZL200410082381.9 "an empty stomach small ribbed floor" declared by the inventor, the hollow filling body is buried in the small dense ribbed building A hollow layer with a "T-shaped" force-bearing section is formed in the cover, which solves the problem of holes in the "T-shaped" force-bearing section of the small dense rib cavity floor. However, the solidification and hard...

Problems solved by technology

[0005] The purpose of the present invention is to promote the integrated process of building energy saving, using a cavity floor slab formed by a steel mesh body to upgrade the existing cavity floor structure system; making full use of the advantages of industrialization of the factory, making a ribbed steel mesh panel, Foamed cement blocks are produced near the construction site and assembled into a steel mesh body on the construction site to solve the problems of construction, environmental protection, weight, production, transportation, work efficiency, and cost existing in the existing cavity floor technology; The structural technology is transformed and upgraded, and the construction quality is improved at the same time, laying a solid foundation for the realization of the multi-functional application of the cavity floor
