Abstract
The utility model discloses a composite floor slab for a steel structure building, and belongs to the field of building profiles. The composite floor slab consists of a precast concrete bottom plate, intermediate keels and a cast-in-situ concrete top layer. The precast concrete bottom plate consists of a hot galvanized steel wire mesh, transverse clamping groove steel strips, side plates and a cast concrete layer, so that the crack resistance and shock resistance of the floor slab are greatly improved. The intermediate keels are longitudinally arranged at intervals, and are fixedly connected with the transverse clamping groove steel strips of the precast concrete bottom plate, so that the stability of the intermediate keels is ensured, and the displacement of the intermediate keels is avoided. The cast-in-situ concrete top layer completely wraps the intermediate keels, so that the casting quality of cast-in-situ concrete is ensured, and the strength of the cast-in-situ concrete top layer is comprehensively strengthened. The composite concrete floor slab is high in rigidity, carrying capacity, crack resistance, shock resistance, heat preservation performance and sound insulation performance, is convenient to manufacture, and can be industrially produced on line, so that the requirements of a high-rise steel structure building and a large-span floor structure for the floor slab can be widely met.

Patent like publication number CN101769030A discloses a kind of prefabricated concrete bottom plate with steel ribs; Comprise on band reinforcing bar rib precast concrete base plate, vertical reinforcing bar rib, prefabricated panel distributing bar, the vertical reinforcing bar rib and reserve suspension ring on reserving hole, the reinforcing bar rib; This prefabricated panel construction is complicated, is not easy to batch production production.
Therefore, overall performances such as the good rigidly, supporting capacity of developing a kind of innovation is strong, cracking resistance, anti-seismic performance are excellent, insulation and sound insulation property are good, makes easy, can carry out the laminated floor slab that batch production produces and be urgent need.
The utility model content
The purpose of the utility model is to provide a kind of steel building to use laminated floor slab; This laminated floor slab is its good rigidly not only; Supporting capacity is strong, cracking resistance, anti-seismic performance excellence, and overall performances such as insulation and sound insulation property are good; And have make easy, can carry out factory's streamlined and produce, thereby can satisfy high-rise steel structure building and long-span floor system structure demand to the high-performance floor.
The utility model steel building is used laminated floor slab; By concrete prefabricated base plate, middle keel and cast-in-situ concrete top layer are formed, and characteristics are that concrete prefabricated base plate is made up of hot-galvanized steel silk screen, horizontal draw-in groove steel band, side plate and casting concrete layer; Side plate is an a pair of right angle base plate; Be arranged on vertical dual-side of concrete prefabricated base plate, gauze wire cloth is arranged between the pair of side plates and is connected with the bottom surface, right angle, and laterally the draw-in groove steel band is provided with at interval and is connected on the gauze wire cloth; Middle keel longitudinal separation is provided with the horizontal draw-in groove steel band of concrete prefabricated base plate affixed; On this concrete prefabricated base plate and middle keel, be the cast-in-situ concrete top layer, adjacent laminated floor slab connects through limit, the corresponding upper edge of its adjacent side plates and is floor plate face continuously.
One of above-mentioned concrete prefabricated base plate is to bottom side, right angle plate, and wherein there is outer crochet a side side plate upper edge, and opposite side side plate upper edge is a straight line.
Keel are C shaped steel, folding shape steel band or steel bar girder in the middle of above-mentioned.
The utility model provides a kind of designed with simple; Can carry out factory's streamlined produces; And be applicable to the high-performance laminated floor slab of high-rise steel structure building and long-span floor system structure, this laminated floor slab is made up of concrete prefabricated base plate, middle keel and cast-in-situ concrete top layer.One of concrete prefabricated base plate is to vertical plate; Connect the location through tapping screw between gauze wire cloth and the horizontal draw-in groove steel band; Form concrete prefabricated base plate through casting concrete; Adopt the pre-buried steel silk screen in the prefabricated panel, not only saved the loaded down with trivial details technology of laying presstressed reinforcing steel in the prior art prefabricated panel, and increased substantially the crack resistance and the shock resistance of floor; Middle keel longitudinal separation is arranged on the horizontal draw-in groove steel band of concrete floor; Bolt connects between the two; Keel do not take place laterally or length travel in the middle of guaranteeing; Reproduce the pouring concrete top layer middle keel are wrapped in the cast-in-situ concrete layer fully, guaranteed the pouring quality of cast-in-situ concrete, strengthened the intensity of cast-in-situ concrete top layer comprehensively.Therefore; The utility model reinforced concrete slab, good rigidly not only, supporting capacity is strong; Cracking resistance, anti-seismic performance excellence; Insulation is good with overall performance such as sound insulation property, and have make easy, can carry out characteristics such as industrialization online production, can satisfy extensively therefore that high-rise steel structure is built and the long-span floor system structure to the demand of floor.
