2. Description of the Related Art Conventionally, in order to move in and out between a scaffold temporarily installed on the outside of a building and a veranda of the skeleton, a stepladder with a step board at the center of the top is fixed to a frame tube appropriately selected from the slab of the veranda and the scaffolding frame. Then, a horizontal footboard is provided on the handrail of the veranda, and a ladder portion is provided on the veranda side and the scaffolding side to form a passage between the scaffold and the veranda to enter and exit.

However, since the floors of the veranda and the scaffold do not normally coincide with each other, a stretchable one is used as the stepladder. As such a stretchable structure, a step stand having a predetermined number of steps is fixed. A pair of both side rods are slidably attached to both side rods with a slightly narrow step base fixed.When adjusting the expansion and contraction of both, the upper and lower rods are fitted with pins in the insertion holes formed at regular intervals. The ones that were inserted and fixed were used.

Further, since it is unstable to simply install the stepladder between the veranda and the scaffold, it is necessary to fix the lower end of the ladder portion to the frame tube on the scaffold side, and as a result, as described above. Due to the fact that the amount of expansion and contraction of the ladder part of the stepladder is gradual, when installing the ladder part to the scaffolding side, carefully adjust the vertical position of the frame tube on the scaffolding side so that the footboard on the upper part of the stepladder is horizontal. Since such a stepladder is made of iron and has a considerable weight, it is difficult to attach the stepladder.
