The technical solution adopted in the utility model is such：A kind of new steel structure stair, including tilting steel ladder beam
And it is arranged at the steel pedal and steel kickplate on steel ladder beam top, the right angle that the steel kickplate in the steel pedal and its underpart is connected
Quarter bend is provided with, the quarter bend length is identical with steel tread length, the steel pedal lower end both sides are horizontally disposed square tube one, institute
State steel kickplate right-hand member both sides and be vertically arranged with square tube two, the square tube one and square tube two are vertical and are connected on the quarter bend.
A kind of new steel structure stair described in the utility model, it is straight that the steel pedal is connected with the steel kickplate on its top
Angle steel is welded with angle, the angle steel length is identical with the steel pedal.
A kind of new steel structure stair described in the utility model, the quarter bend is welded in the steel pedal and steel kickplate is straight
At angle, the square tube one is welded with the steel pedal and quarter bend, and the square tube two is welded with the steel kickplate and quarter bend.
A kind of new steel structure stair described in the utility model, in the steel pedal upper surface and the steel kickplate left end
Face is fixed by concrete layer and is equipped with decorative layer.
A kind of new steel structure stair described in the utility model, the steel pedal upper surface and the steel kickplate left side
Setting is welded with round steel, and the concrete layer covers the round steel.
A kind of new steel structure stair described in the utility model, in the steel ladder beam, square tube one, square tube two and quarter bend shape
Into triangle end face be welded with side shield.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：The utility model structure
Intensity is reliable, and amount of deflection is small, can adapt to the larger steel structure stairway of width and manufactures and designs, and can be laid on steel structure stairway surface
Decorative layer so that stair are more attractive in appearance.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Marked in figure：1 is steel ladder beam, and 2 be steel pedal, and 3 be steel kickplate, and 4 be quarter bend, and 5 be square tube one, and 6 be square tube two, 7
It is concrete layer for angle steel, 8,9 be decorative layer, and 10 be round steel, and 11 be side shield.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
