Technical Field
The utility model relates to a climb a technical field, especially one kind be provided with bracing piece and extension rod, adopt the installation of assembled structure, handrail simultaneously not at same plane, thereby be convenient for mass production and good reliability's scalable stair.
Background
The climbing frame, also called as an attached lifting scaffold, has developed rapidly in nearly more than ten years, gradually developed into a more mature industry, and mostly adopts an attached lifting scaffold of an all-steel type. Because climb the frame and have turnover rate height, save material, pollute characteristics such as few, fire prevention, degree of automation height, compare traditional scaffold frame safe and reliable and lightweight more simultaneously, consequently receive the favor of building trade construction unit deeply.
The frame that climbs generally is space truss structure, according to the distribution of scaffold frame, generally has the multistep, and the step height is mostly 2m, nevertheless because constructor will carry out the operation between each step, if regard the building floor as walking channel, can cause because floor and frame step are inconsistent, causes the difficulty of passing through. At present, the general solution is to reserve a stair between each step, so that constructors can access to a target step layer through the stair.
However, in the using process, due to special scenes or special arrangement requirements, some steps are inconsistent with the standard steps, and the height and the angle of the stairs are generally redesigned, so that the standardization degree of the stairs is poor, and the modular production of the stairs is difficult to realize. There are some flexible stairs among the prior art, but most flexible stairs only have flexible function, can not realize the personnel protection betterly, and for the terminal processing convenience of telescopic link, it is many direct with the incision as the impetus moreover for current flexible stair's stability is unsatisfactory, can appear rocking the condition when personnel climb, and it is inconvenient that the installation is dismantled to the most of current stair simultaneously, and the modularization degree is poor.
Disclosure of Invention

the two support rods are symmetrically arranged, the two handrails are arranged on the support rods and symmetrically arranged, and each handrail is connected with the support rods through fastening bolts;
and two ends of the single pedal are rigidly connected with the supporting rod.
Furthermore, the pedals are formed by bending integrated metal plates, the distance between every two adjacent pedals is consistent, the distance between the pedal arranged at the uppermost end of the supporting rod and the upper end of the supporting rod is smaller than the distance between every two adjacent pedals, and leg lifting of personnel when the personnel ascend to the upper scaffold board can be reduced;
furthermore, the distance between the mounting holes of the extension rod is a multiple of the distance between the mounting holes on the support rod, so that the adjustment of the small distance of the extension rod can be realized;
furthermore, the handrail is formed by welding a steel pipe and a steel plate, the steel pipe adopts an arc-shaped structure which is convenient for constructors to grasp, and the safety of the constructors during climbing can be ensured;
furthermore, the edge position of the pedal is bent downwards, so that the reinforcing effect is achieved, the structural strength of the pedal is guaranteed, and the pedal is an integrated piece, so that the batch production can be conveniently realized;
further, the front end inclined plane of bracing piece sets up the handrail mounting hole, just the up end of bracing piece sets up the handrail mounting hole, the handrail mounting hole on the bracing piece up end is installed to the top of handrail, the centre and the lower extreme of handrail are installed in the handrail mounting hole on bracing piece front end inclined plane, can prevent effectively that the handrail from toppling to one side, further strengthen constructor's security.
The utility model relates to a scalable stair for climbing frame, its beneficial effect has:
1. the assembled structure is adopted, batch production can be conveniently carried out, and meanwhile, the sheet-shaped structure is adopted, so that the occupied space during transportation can be reduced;
2. by adjusting the relative positions of the extension rod and the support rod, reliable length change and stable support can be quickly realized;
3. compared with the installation mode of the handrails in the prior art, the installation of the handrails is not on the same plane, so that the stability and the reliability of the handrail and the supporting rods are fully guaranteed when constructors climb the handrail, the handrail is prevented from shaking, and the safety of the stairs is improved.
