To efficiently and safely set a scaffold to be provided on a support pile.
Two vertically arranged guide rollers 5 are juxtaposed at an arrangement space equal to the opposite space of the flanges 50f of the H-steel 50 of the support pile and fixed to the respective inner opposed surfaces of a front part 1 and a back part 6, a receiving base 10 is assembled in the form of engaging the guide rollers 5 with the flanges 50f, and a working floor 20 is fixed to the upper surface thereof. This scaffold 100 is smoothly movable along rails by the drive of a suspending rope by use of the end parts of the flanges 50f of the H-steel 50 as the rails and the guide rollers 5 as wheels. Accordingly, even if the setting height of a stress member is changed in one support pile 50, this scaffold 100 alone is quickly conformable to this by its movement. After the movement, the engagement of the guide rollers 5 with the flange 50f end parts of the H-steel 50 achieves the horizontal fixing effect of the scaffold 100 as it is. This scaffold also plays the role of a carrying means for materials.
