In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of steel staircase concrete face slab,
Alternately connect and compose step-like successively by some tread panels and riser panel normal thereto, it is concrete formed by integrally casting,
The tread panel bottom is provided with pre-embedded steel slab, for the tread panel to be fixedly welded on to the steel ladder beam of steel staircase
On, preset otic placode is provided with the top of wherein at least two tread panel, for lifting the steel staircase concrete face slab.
Preferably, being provided with two pre-embedded steel slabs in the tread panel, it is located at one end of the tread panel respectively.
Optionally, the pre-embedded steel slab bottom surface is concordant with the tread panel bottom surface.
Further, it is equipped with reinforcing bar network framework in the tread panel and riser panel.
Optionally, the steel staircase is tread panel with the head and the tail both ends of concrete face slab.
Preferably, the tread panel is four, and the riser panel is three.
It is using beneficial effect caused by above-mentioned technical proposal：The utility model provides a kind of steel staircase concrete face
Plate, it is simple in construction, it is easily manufactured, can quickly, batch it is prefabricated, by pre-embedded steel slab can easily with stair girder steel arrange in pairs or groups connect
Connect, installation rate is fast, concrete face slab after lifting is fixed, the preset otic placode on its top can spot welding remove, the upper surface of concrete face slab can
Building coats construction is carried out, having preferably can be ornamental.

Embodiment
It is new to this practicality with reference to the accompanying drawings and detailed description in order to clearly describe the utility model
Type is described in further detail.
A kind of steel staircase concrete face slab, alternately connected successively by some tread panels 1 and riser panel 2 normal thereto
Form step-like, it is concrete formed by integrally casting, sees Fig. 1, and the bottom of tread panel 1 is provided with pre-embedded steel slab 4, sees Fig. 1, Fig. 3, is used
In tread panel 1 being fixedly welded on the steel ladder beam 5 of steel staircase, see Fig. 4, Fig. 5, wherein at least two tread panel 1
Top is provided with preset otic placode 3, for lifting steel staircase concrete face slab, sees Fig. 2.
Wherein, the number of tread panel 1 and riser panel 2 needs to be selected according to the design of steel staircase.In general,
The head and the tail both ends of concrete face slab are tread panel 1, as shown in figure 1, however, according to the design needs, those skilled in the art can
Voluntarily concrete face slab head and the tail both ends are selected to select tread panel 1 or riser panel 2.
It is as shown in Figure 1 a kind of preferred embodiment of the utility model steel staircase concrete face slab, steel staircase concrete face
The head and the tail both ends of plate are tread panel 1, and tread panel 1 is four, and riser panel 2 is three, its mark time size according to《House
Design specification》GB50096-2011 is set.Wherein, preset otic placode 3 is respectively arranged on head and the tail both ends tread panel 1 each two.In advance
Annulus hanger, after the present embodiment steel staircase is fixed on steel ladder beam 5 with concrete face slab, preset otic placode 3 can be used by putting otic placode 3
Removed through spot welding, the concrete surface of concrete face slab upper surface can dabbing, later stage building coats construction is carried out, such as tiling, laying ground
Plate etc., having preferably can be ornamental.
A kind of embodiment of the bottom pre-embedded steel slab 4 of tread panel 1 in the utility model, pre-embedded steel slab 4 are and tread face
Parallel one of plate 1, the both ends of the both ends of pre-embedded steel slab 4 respectively with tread panel 1 flush.
The present embodiment uses preferred embodiment as shown in Figure 3, and two pre-embedded steel slabs 4, its point are provided with tread panel 1
Not Wei Yu tread panel 1 one end, can reduce the deadweight of concrete face slab, reduce manufacturing cost, be easy to assemble.
In the present embodiment, the bottom surface of pre-embedded steel slab 4 is concordant with the bottom surface of tread panel 1, is easy to manufacture.As optional embodiment party
Formula, pre-embedded steel slab 4 expose the bottom surface of tread panel 1, and the steel ladder beam 5 assembled therewith is provided with the groove to match, and pre-embedded steel slab 4 fills
