Shape steel plate and lower end tilt troughing plate, and both sides are fixedly connected by long web, and the other end is fixed by stenogastry plate to be connected
Connect, form support frame structure；The stenogastry plate of adjacent step cell cube is fixed together with long web by connecting bolt
Form stairs frame；Fixing bolt between stenogastry plate and long web rearranges the downward arch block channel of convex arc,
Steel strand wires are set up in setting area between stenogastry plate and long web, and steel strand wires are after the arrangement of each arch block channel, its two ends
The stenogastry plate and long web that two outer ends are arranged at by adjusting strainer are sealed；It is most upper after each step cell cube combination
End and cushion cap surface matching, pre-embedded bolt is set on cushion cap surface, and step cell cube is fixed on cushion cap by pre-embedded bolt；
Decoration panel is provided with the outside of each step cell cube.
Bottom diagonal brace steel plate is fixed with the bottom of the stairs frame.
The end of the steel strand wires is fixed with fixed swivel nut by locking pin, and the adjusting nut is arranged on fixed swivel nut
On, the inner surface setting of adjusting nut has unidirectional active anti-slop serrations, and the outer surface of lock washer is provided with unidirectional passive anti-slop serrations, two
Engagement can be matched by planting anti-slop serrations, and positioning hole is additionally provided with the lock washer, and anti-rotation expansion is provided with the positioning hole
Silk, anti-rotation expansion thread is fixed on gathering hole bottom surface.
In upper end, the bottom surface of horizontal troughing plate is provided with rib in length and breadth, and the end of rib is docked with wing plate in length and breadth is fixed as
One.
Beneficial effect：The utility model can quickly splice composition combined staircase by way of step cell cube is docked,
Because step cell cube is made up of troughing plate and web up and down, self-strength is high, after combination between adjacent each web again that
This overlapping fixation, bulk strength is high.There can be very high intensity high in longitudinal direction in conjunction with bottom diagonal brace steel plate is thick.Simultaneously
Prestress wire is pressurized on the inside of adjacent step cell cube, stair horizontal span can be increased, so that it is strong to meet actual stair
Degree is required.The utility model and cushion cap integrated structure simple and stable, are adapted to Rapid Combination and dismounting, and each step cell cube model is same
One is easy to store and transports, and use value is high.
