[0026] During assembly, you only need to place the two second cross bars at the corresponding positions between the two first cross bars, then contact the mounting plate to the side wall of the sleeve, and finally connect them with bolts. The entire assembly process is convenient and quick. When constructing a high-rise step platform, you can first connect the two first cross bars to the columns through the sleeve, and then install the second cross bar between the two first cross bars. This can reduce the lifting weight of the construction workers and facilitate the assembly operation of the step platform.

[0027] The pedal member 11 is in the shape of a rectangular plate, and the length direction of the pedal member 11 is consistent with the length direction of the second cross bar 131.

[0034] The utility model adopts a design in which the pedal platform is composed of two first cross beams and two second cross beams. When assembling, the two first cross beams and the two second cross beams can be bolted together and a pedal part can be placed thereon to form a split-structure pedal platform.
