Detailed description of the invention
Below by way of specific instantiation, embodiments of the present invention are described, those skilled in the art the content disclosed by this manual can understand other advantages of the present invention and effect easily.The present invention can also be implemented or be applied by detailed description of the invention different in addition, and the every details in this manual also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present invention.
Be introduced below in conjunction with the syndeton of accompanying drawing to precast floor slab of the present invention and girder steel:
As depicted in figs. 1 and 2, the syndeton of precast floor slab of the present invention and girder steel comprises: girder steel 10, prefabricated floor support plate 11 and cast-in-situ concrete layer 12.The upper surface of prefabricated floor support plate 11 is provided with many vertical floors 13.The upper surface being erected on a girder steel 10 is respectively taken on the both sides of prefabricated floor support plate 11.Cast-in-situ concrete layer 12 builds the upper surface of upper surface in prefabricated floor support plate 11 and girder steel 10, and vertical floor 13 is embedded in inside concrete.The vertical floor 13 of prefabricated floor support plate 11 can strengthen intensity and the enabling capabilities of prefabricated floor support plate 11 greatly, therefore do not need thereunder to set up braced structures in the process of the upper surface concreting of prefabricated floor support plate 11, can save like this braced structures set up and demolishing process consume time.
As shown in Figures 2 and 3, in the present embodiment, vertical floor 13 is parallel to each other, and the axes normal of vertical floor 13 and girder steel 10.This arrangement mode of vertical floor 13 can give full play to the booster action of vertical floor to prefabricated floor support plate 11, thus effectively improves intensity and the enabling capabilities of prefabricated floor support plate 11.The vertical floor 13 of every bar comprises corrugated web 14 and frange plate 15.Frange plate 15 is arranged in the horizontal direction; Corrugated web 14 is vertically arranged.The top of corrugated web 14 is connected to the soffit of frange plate 15, is connected to the upper surface of prefabricated floor support plate 11 bottom it.Prefabricated floor support plate 11 and frange plate 15 are made by concrete, and the bottom sides of corrugated web 14 is along being embedded in prefabricated floor support plate 11, and the top sides of corrugated web 14 is along being embedded in frange plate 15.
As Fig. 2 and Fig. 3, corrugated web 14 is made up of corrugated steel, the top sides edge of corrugated web 14 and bottom sides are along being all welded with the wing plate 16 arranged in the horizontal direction, the wing plate 16 at corrugated web 14 top is embedded in frange plate inside, and it is inner that the wing plate 16 bottom corrugated web 14 is embedded in prefabricated floor support plate 11.Wing plate 16 makes the connection of corrugated web 14 and prefabricated floor support plate 11 and frange plate 15 more firm.The horizontal section of corrugated web 14 is the ripple periodically repeated.The sectional area shape of the corrugated web of corrugated web 14 effectively can improve the mechanical property of vertical floor 13, thus effectively strengthens the intensity of prefabricated floor support plate 11.
As shown in Figure 1, the upper surface of girder steel 10 is welded with shear stud 17, and shear stud 17 is embedded in the inside of cast-in-situ concrete layer 12.Shear stud 17 can increase the bonding strength between cast-in-situ concrete layer 12 and girder steel 10.
As shown in Figure 1, in the present embodiment, prefabricated floor support plate 11 is made up of steel concrete, and the cast-in-situ concrete layer 12 that the part reinforcing bar 18 of prefabricated floor support plate 11 inside extends to above girder steel 10 is in the horizontal direction inner.The reinforcing bar extending to cast-in-situ concrete layer 12 inside effectively can strengthen the bonding strength between prefabricated floor support plate 11 and cast-in-situ concrete layer 12.
The above is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, although the present invention discloses as above with preferred embodiment, but and be not used to limit the present invention, any those skilled in the art, not departing from the scope of technical solution of the present invention, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solution of the present invention, according to any simple modification that technical spirit of the present invention is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
