Abstract
The invention relates to a laminated floor slab for steel buildings, which belongs to the field of building profiles and comprises a prefabricated concrete bottom plate, middle keels and a cast-in-place concrete top layer. The prefabricated concrete bottom plate is composed of a hot galvanized wire mesh, transverse clamping channel steel strips, side plates and a cast concrete layer. Crack resistance and seismic resistance of the floor slab are improved greatly. The middle keels are longitudinally disposed at intervals and fixedly connected with the transverse clamping channel steel strips of the prefabricated concrete bottom plate, so that stability and no shifting of the middle keels are ensured. The middle keels are totally enclosed in the cast-in-place concrete layer by the cast-in-place top layer, so that casting quality of cast-in-place concrete is guaranteed, and the strength of the cast-in-place concrete top layer is fully enhanced. The laminated floor slab is high in rigidity, high in bearing capacity, crack-resistant, excellent in seismic resistance, excellent in overall thermal insulation and sound insulation properties, simple in manufacture and available for industrial on-line production. Therefore, the requirements of high-rise steel buildings and large-span floor systems on floor slabs can be widely met.
Description
Technical field
Steel building of the present invention is used laminated floor slab, belongs to the architectural shape field.
Background technology
At present, the floor form of domestic employing has cast-in-situ floor and precast floor slab, the cast-in-situ floor good integrity, but need on-the-spot formwork, concreting; Long construction period, difficulty are greatly, the template consume is big, cost is high, and precast floor slab does not need on-the-spot formwork, short construction period, and cost is low; But prefabricated units are from great, and lifting is difficult, and the component assembly position is prone to produce the crack, and globality is poor; Also there is deficiency in existing laminated floor slab, is that the patent of CN1254589C discloses a kind of prestressed concrete precast member board with ribbing like publication number, comprises reinforced concrete floor, steel concrete longitudinal rib and bottom presstressed reinforcing steel; This prefabricated panel band concrete perforation rib, to wear reinforcing bar convenient at present, but frangible in this precast member board transportation and the lifting; Prefabricated panel presstressed reinforcing steel complex manufacturing technology, the antiarch value of prefabricated units is bigger, and base plate is thinner; Its inner presstressed reinforcing steel that exists causes the floor fire line poor performance after superimposed, supports at the bottom of more plate need be set in the construction simultaneously, is not suitable for the long-span floor system structure.
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.
Summary of the invention
The object of the present invention 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.
Steel building of the present invention 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 present invention proposes 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; Reinforced concrete slab of the present invention, 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.
