Hollow floor system made of steel bar and foam combined filled member

Abstract

The invention provides a hollow floor system made of a steel bar and foam combined filled member. The hollow floor system comprises an upper flange, a rib beam, a lower flange and the steel bar and foam combined filled member, wherein the steel bar and foam combined filled member consists of a plastic foam body and a steel bar body; the steel bar body comprises an isolation steel bar and support steel bars; the isolation steel bar and the support steel bars of the steel bar body are integrally manufactured or welded into a whole; the isolation steel bar is arranged on the upper surface of the plastic foam body; the support steel bars pass through the plastic foam body; the length of the support steel bars is greater than the height of the plastic foam body; and support points of the support steel bars are positioned on a template of the hollow floor system. A top plate steel bar and a bottom plate steel bar of the hollow floor system can be prevented from contacting or sinking into the plastic foam body, and the problem of insufficient bond stress of the steel bars and cast-in-situ concrete in the prior art is effectively solved; and cost can be saved, and the floor system is more conveniently and quickly constructed and has a more reasonable structure.

Description

technical field [0001] The invention relates to a novel building floor, in particular to a hollow floor made of reinforced foam composite filling components. Background technique [0002] At present, in the technical field of cast-in-place reinforced concrete cavity floors, cavity thin-walled box components are usually used to form cavity floors, such as ZL02282207.0 "Thin-walled box embodies thin-walled cavity panels for pouring cavity panels" declared by the inventor. According to the patent, the thin-walled box produced by inorganic cement cementitious material has thin hollow wall, light weight and high strength, and is widely used in cavity floor projects, such as the ZL200410082381.9 "one" declared by the inventor A kind of cavity small ribbed floor", the cavity thin-walled box forms a hollow layer in the small dense ribbed floor, which can save concrete for construction, reduce the height of the building, increase the sound insulation effect of the floor, and improve ...

Problems solved by technology

[0003] However, because this kind of hollow floor uses a hollow thin-walled box made of pure inorganic cement cementitious material, the cement cementitious material used to make the thin-walled box takes a long time to solidify and harden, the utilization rate of molds and labor is low, and the hardened The density of the cement cement material is high, and the weight of the thin-walled box made of the cavity is heavy, which is inconvenient for production, transportation and on-site construction. Therefore, organic plastic foam is used to make hollow floor filling components on the market. figure 1 That is, the cross-sectional view of the hollow floor structure using plastic foam filling components in the prior art, such as figure 1 As shown, after the hollow floor formwork 2 is built, the base plate steel bars 3 are laid on the formwork 2, and the rib steel bars 4 are bound. A mesh-like space is formed between the rib steel ba
