It is preferred that the fastener includes gasket and bolt, the gasket pad is set on adjacent supports bar, bolt
It across gasket, is threadedly connected in the screw hole of the supporting rod bottom, the adjacent supporting rod is connected and fixed.
It is preferred that the back side of two supporting rods of the stairway unit is respectively equipped with U-typed plate and slot.
It is preferred that the plate at the supporting rod back side is inserted in the slot of adjacent supports bar.
It is preferred that the pedal is connect by the holder at both ends with the supporting rod.
It is preferred that the concave of anti-skidding effect has been equipped on the pedal in left-right direction.
It is preferred that the pedal is equipped with several through-holes.
It is preferred that the scaffold sets up into " H " type frame by three steel pipes, the infall of the steel pipe passes through
Connector connects.
The utility model is related to a kind of construction stair of simple-mounting-dismounting the advantage is that compared with existing design：First,
The utility model can be according to field demand by the horizontally-spliced laying of multiple stairway units, only need to be by the arc groove in stairway unit
It is hung on scaffold, installation fastener can be used, easy to operate, and dismounting is simple.Secondly, supporting rod back side plate and slot
Use, contribute to the stability laterally when being laid with.Furthermore stair tread is equipped with hole and concave, can prevent sediment accumulation, rise
Anti-skidding effect, while improving the safety and reliability of construction stair；In addition, this device can build dismounting at any time, compared to utilization
It is more time saving and energy saving that material in situ is built, and repeatable utilization, avoids waste material.

Specific implementation mode
The utility model is related to a kind of construction stair of simple-mounting-dismounting, including scaffold 10 and it is placed on scaffold 10
At least one stairway unit 20；The utility model is described in detail below in conjunction with Fig. 1-6 and specific embodiment.
As shown in Figs. 1-3, each stairway unit 20 includes the supporting rod 21 of left and right two parallel intervals setting, two supports
Stepped spaced several pedals 22 are welded between bar 21, further, pedal 22 by the holder 23 at both ends with
Supporting rod 21 connects.Arc groove 211 is opened up at the top of supporting rod 21, the lower end of supporting rod 21 is equipped with fastener 212；Fastening
Part 212 includes the screw hole 2123 of two 21 upper base surfaces of supporting rod, the spiral shell being threadedly connected in a wherein supporting rod screw hole
Bolt 2122 and hang on bolt the gasket 2121 there are two hole.As seen in figs. 5-6, two supporting rods 21 of stairway unit 20
The back side be respectively equipped with U-typed plate 214 and slot 215, plate is welded on supporting rod.
Further, as shown in figure 3, being equipped with the concave 221 of anti-skidding effect and several logical on pedal 22 in left-right direction
Hole 222 can prevent sediment accumulation, play safety and reliability that is anti-skidding, while improving construction stair.
Further, as shown in Figure 1, scaffold 10 sets up into " H " type frame, the intersection of the steel pipe 11 by three steel pipes
Place is connected by connector 12.
Further, the supporting rod 21, pedal 22, holder 23 material be steel, load bearing effect is notable, increase safety
Property.
As shown in figures 1 to 6, the construction stair of the utility model simple-mounting-dismounting include that multiple stairway units 20 or so are spliced, solution
The certainly narrow problem of construction stair in work progress, and stress can be reduced after the single lateral connection laying of this stair, it is transporting
Defeated weight is safer.So that the plate 214 at 21 back side of supporting rod is inserted in the slot 215 of adjacent supports bar 21, directly keeps away
The stairway unit for exempting from left and right splicing shakes unstable problem.The arc groove 211 of support bar top adaptedly holding in scaffold
On the steel pipe 11 at 10 tops, stairway unit is ridden upon on scaffold successively, stair top curve groove 211 and scaffolding steel pipe
Size is seamless to agree with, without separately adding connecting elements to can be solved the support problem of stair.Rotation gasket make another hole with it is adjacent
After screw hole alignment on supporting rod, it is selected into bolt, you can reinforce two neighboring supporting rod.
