step 2, splicing the plurality of step structure units according to the length of the side slope to form a stair step main body;
and 3, fixing a plurality of handrail upright posts on two sides of the step main body through rivets, arranging soft ropes on the handrail upright posts on the two sides, and tensioning the soft ropes by using turn buckle bolts.
The invention has the following advantages:
1. safety and stability. Two sides of the pedal are connected with the vertical supporting rod and the oblique supporting rod through standard bolts to form a triangular structure, so that a three-dimensional triangular step structure unit is formed; then, sequentially assembling the stepping units, wherein the stepping structure units and the upper and lower pedals form a stable triangular stress body structure; the triangular plane structure is used for reinforcing a stable stress body, so that the problem of safety and stability in the use process on different slopes with different slope rates is solved.
2. The assembly and disassembly are convenient. The pedal is connected with the vertical supporting rod and the inclined supporting rod through standard bolts to form a complete step, the step and the step are spliced to form the slope stair with the required length only through standard bolt connection, so that the assembly and disassembly are simple, the time is saved, the assembly can be simultaneously carried out on any place and multiple points on the side slope, the number of components is small, the weight is light, and the construction period is shortened.
3. And (4) slope rate adaptability. The vertical supporting rod and the oblique supporting rod are provided with a plurality of connecting holes, different hole sites meet the requirements of different slope rates and different fields for erecting the assembled stair step, the whole stress is reasonable, the use is comfortable, and the invention has wide adaptability.
4. The standard bolt can be tightened or loosened through the manual ring without the aid of tools.
5. This regularization product can be according to the actual concatenation in scene and set up into rest platform.
