The utility model content
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of, precast beam and permanent steel board composite floor system that plate stride less, duration tight engineering higher for floor height are provided.
A kind of precast beam and the permanent steel board composite floor system that provide according to the utility model, comprise precast beam, permanent steel board and cast-in-situ slabs reinforced concrete, it is characterized in that precast beam upper surface dew has stirrup, permanent steel board is held on adjacent two precast beams, and reinforced concrete slab is cast-in-place on precast beam and steel board.
A kind of precast beam and the permanent steel board composite floor system for small-slab span that provides according to the utility model also has following attached technical characterictic:
The bottom of described precast beam is embedded with elongated pretensioned prestressing steel strand, and the top of precast beam also is embedded with prestress wire.
Described permanent steel board is die mould closed steel board, and its vertical rib is tight T font.
The vertical rib bottom of described permanent steel board is provided with some through holes of wearing transverse reinforcement.
Described permanent steel board is steel bar truss floor support plate, and its galvanized steel plain sheet that is welded in the steel bar girder bottom is having the precast beam place to be interrupted certain-length.
Be provided with adhesive tape between permanent steel board and precast beam upper surface.
At the bottom of the described Bars In Poured Concrete Slab plate and the plate face all be embedded with two-way concrete slab, reinforcing bar stretches in the Cast-in-place concrete of beam top, the stirrup internal upper part that exposes on the beam is embedded with longitudinal reinforcement.
Described precast beam is rectangular beam or inverted T-beam.
A kind of precast beam and the permanent steel board composite floor system for small-slab span that provides according to the utility model compared with prior art has following advantage:
1, to be generally used for case bay little also be that plate is striden less superstructure to the utility model, so steel board thickness is little, and steel board cost is low and gross thickness floor is also less.
2, need not form removal, template is laid convenient, and speed of application is fast, is used for the higher engineering of floor height, and formwork cost declines to a great extent, the construction safety civilization.
3, plate and whole the watering of superposed beam top concrete one-off, the two-way reinforcing bar of joining of plate, so superstructure good integrity.
4, beam slab all need not to whitewash, and not only cost reduces, and the construction period shortens.

The specific embodiment
Referring to Fig. 1 to Fig. 3, a kind of precast beam that provides at the utility model and the embodiment of permanent steel board composite floor system, comprise precast beam 1, permanent steel board 2 and cast-in-situ slabs reinforced concrete 3, it is characterized in that precast beam 1 upper surface dew has stirrup 11, permanent steel board 2 is held on adjacent two precast beams 1, and reinforced concrete slab 3 is cast-in-place on precast beam 1 and steel board 2.As support member, it does not pull down steel board 2 in the utility model after the construction when construction, but directly jointly stressed with floor as a part of superstructure.This structure not only speed of application is fast, and safety factor is higher.
Referring to Fig. 1, in above-described embodiment that the utility model provides, the bottom of described precast beam 1 is embedded with elongated pretensioned prestressing steel strand 12, and the top of precast beam 1 also is embedded with prestress wire 13.The precast beam 1 that is embedded with prestress wire 12 has preferably anti-bending strength, and its weight is lighter comparatively speaking, is beneficial to lifting.
Referring to Fig. 3 and Fig. 4, in above-described embodiment that the utility model provides, described permanent steel board 2 is die mould closed steel board 22, and its vertical rib 221 is tight T font.Its global shape as shown in FIG., wherein the vertical rib on the steel board is imbedded in the cast-in-situ slabs reinforced concrete 3, the palette end can spillage for the vertical rib 221 of remaining silent, and can also be jointly stressed with the concrete combination, its bending resistance is also stronger when watering concrete.
Referring to Fig. 4 and Fig. 6, in above-described embodiment that the utility model provides, vertical rib 221 bottoms of described permanent steel board 2 are provided with some through holes 222 of wearing transverse reinforcement.Described through hole 222 is used for walking the reinforcing bar of cast-in-situ slabs reinforced concrete 3, makes plate become bi-directional pressured plate, and globality is also strengthened.
Referring to Fig. 1 and Fig. 3, in above-described embodiment that the utility model provides, be provided with adhesive tape 4 between permanent steel board 2 and precast beam 1 upper surface.Described adhesive tape 4 plays the effect of sealing, prevents the slit source concrete between steel board 2 and the precast beam 1.
Referring to Fig. 1 and Fig. 3, in above-described embodiment that the utility model provides, at the bottom of described cast-in-situ slabs reinforced concrete 3 plates and the plate face all be embedded with two-way concrete slab 5, reinforcing bar 5 stretches in the Cast-in-place concrete of beam top, the stirrup internal upper part that exposes on the beam is embedded with longitudinal reinforcement 6.Two-way slab reinforcing bar 5 and longitudinal reinforcement 6 are the flexural strength needs that satisfy plate and beam, and make prefabricated and cast-in-place part jointly stressed.
Referring to Fig. 1 and Fig. 3, in above-described embodiment that the utility model provides, described precast beam 1 is rectangular beam or inverted T-beam.These precast beams 1 are provided with prestress wire, and can satisfy needs of the present utility model.
