Abstract
The invention discloses a nuclear radiation prevention hollow floor cover. Reinforcing steel bars and concrete are arranged around a tank body, a foaming body with the function of neutron absorption is arranged in a cavity of the tank body, and a top plate and a bottom plate of the tank body are made of radiation prevention concrete prefabricated parts. The nuclear radiation prevention hollow floor cover has the technical effects that the tank body in the floor cover comprises a radiation prevention top and the bottom plate, and the material of a neutron absorption foaming body is filled in the cavity, so that the nuclear radiation prevention hollow floor cover has the functions of the multilayer shielding as well as the adsorption of rays, neutrons and other radiating particles. After being used, the floor cover can reduce the consumption of the reinforcing steel bars and the concrete, the effective load of the floor cover is increased, the thickness of the floor cover is reduced, the grades of seismic resistance, nuclear radiation resistance and impact wave resistance of a building are improved, the construction cost is reduced, and the using function of the building is improved.
Description
Technical field
The present invention relates to building material field, specifically is a kind of anti-nuclear radiation hollow building cover.
Background technology
Along with the promulgation of Ministry of Construction's " cast-in-place concrete hollow building roof structure technology rules " and " assembling case concrete hollow building roof structure technology rules ", China is in recent years in this structural system of architectural a large amount of employings.The prefabricated noggin piece that needs to place different shape in the superstructure that adopts this structural system to design.At present this prefabricated noggin piece is by at the hollow cement casing of the different shape of factory process moulding etc. mostly.Job practices is earlier hollow box body to be put into superstructure, fluid concrete then as requested; In civil air defense constructions and installations, also there is relevant regulations in country, and superstructure will have the thick concrete cover of 200mm; to strengthen anti-nuclear radiation and tough effect, still this way makes also corresponding having increased of thickness of superstructure, and deadweight strengthens; function limitation, cost has also increased simultaneously.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of anti-nuclear radiation hollow building cover, superstructure adopts the hollow building cover design, in superstructure, place the hollow box body member, the partially filled foam material that the neutron absorption function is arranged of the cavity of hollow box body, the top of casing, base plate are the radiation shield concrete prefabricated units.
Technical scheme of the present invention is achieved in that anti-nuclear radiation hollow building cover, places the hollow box body member in the superstructure, around casing reinforcing bar and concrete is arranged, and the foaming body of neutron absorption function is arranged in the cavity of described casing.
The top board of described casing and base plate are the radiation shield concrete prefabricated units.
The foaming body of described neutron absorption function is that the matrix material that adds neutron-absorbing material prepares through foam process, described neutron-absorbing material be in boron carbide, ferrite, rare earth compound, lithium hydride, graphite and the paraffin one or more, described matrix material is cement or high molecular polymer or both mixing.
Described high molecular polymer is one or more in polyethylene, polyvinyl alcohol, polyurethane, epoxy resin, methacrylic resin, ethylene propylene diene rubber and the polyaniline.
Technique effect of the present invention is: casing adopts radiation proof top, base plate in the superstructure.The partially filled neutron of cavity absorbs foaming body, and shielding that can be multi-level like this absorbs ray, radiating particles such as neutron.Adopt this hollow building cover design, can strengthen floor span, strengthen the floor useful load, reduce slab thickness, reduce the steel concrete consumption of building, improved the antidetonation of building, radioresistance, tough grade reduces building costs, improves the function of use of building.
