Novel steel bar truss composite floor slab

Abstract

The invention discloses a novel steel bar truss composite floor slab. The novel steel bar truss composite floor slab comprises a necking type profiled steel sheet, a concrete prefabricated layer and a steel bar truss, wherein the steel bar truss comprises an upper chord steel bar, a lower chord steel bar and a truss abdomen supporting steel bar; the truss abdomen supporting steel bar is welded on the upper chord steel bar and the lower chord steel bar to form the steel bar truss; and the steel bar truss is welded on the necking type profiled steel sheet through the lower chord steel bar. According to the novel steel bar truss composite floor slab, the necking type profiled steel sheet is adopted so that the binding power between the profiled steel sheet and lower-layer concrete is improved and the thickness of the prefabricated layer is reduced; the novel steel bar truss composite floor slab is combined with the suitable steel bar truss and the strength of the upper chord steel bar and the lower chord steel bar of the steel bar truss is sufficiently utilized; transverse steel bars are paved on site and bidirectional plate reinforcement is easily realized; furthermore, the concrete below the necking type profiled steel sheet can be used as a protection layer of the lower chord steel bar and the profiled steel sheet; the effect of the profiled steel sheet is effectively utilized and the strength and rigidity of a prefabricated part are enhanced; and the problems of beauty, fireproof spraying and anticorrosion maintenance do not need to be considered.

Description

technical field [0001] The invention relates to the technical field of laminated floor slab production, in particular to a novel reinforced truss laminated floor. Background technique [0002] The existing floor bearing plate series products in the industry are widely used in floor structures, large-span structures, falling slab structures, slope roofs, residential structures, thick plate structures, etc., and are often used in power plants, power equipment companies, automobile showrooms, steel structures Factory buildings, cement warehouses, steel structure office buildings, airport terminal buildings, railway stations, stadiums, concert halls, grand theaters, large supermarkets, logistics centers and other steel structure buildings. At present, the concrete composite floor deck series mainly has the following three structural forms: the first type, the open type floor deck series; the second type, the closed type floor deck series; the third type, the reinforced truss flo...
