As shown in the figure, it is preferable to provide several screws from the sheath tube 14 inserted into the column 2 by means for screwing into screw holes (not shown) formed in a plurality of stages in the longitudinal direction of the column 2.

To assemble using the above members, FIG.
As shown in the figure, the lower block 4 of the column 2 is fixed, the tip of the column 2 is connected to the upper block 3 integral with the step board 1, and the tip of the connecting rod 5 projecting from the lower block is connected to the lower block. Steps can be formed by inserting the bolts 4 into the receiving holes 10 and tightening the bolts, and a plurality of columns 2 to be supported on the floor surface are provided according to the configuration of the steps. still,
Since each step board 1 is supported by one column 2, the steps assembled in this manner cannot be independently raised and held. However, the connecting rod 5 projecting from the top step board 1 is used as a building frame or the like. By fixing to the floor surface and fixing the pillar 2 supporting the floor to the floor surface, it is possible to stably build the structure without falling down.

However, in the above-mentioned example, one support plate 2 is used to support one step board 1. However, the support is not necessarily limited to one, and as shown in FIG. In some cases, the support 1 may be configured to be supported by two or three right and left columns 2.
