As a result, the outrigger (5) is attached to the column (2) so as to be rotatable about the first vertical column (71).

The outer peripheral surfaces of both the upper and lower insert members (78) and (79) are cylindrical, and the diameter of both is equal to that of both flanges (22) of the first and second fixtures (21A) and (21B) of the strut (2). is equal to or slightly smaller than the distance between the inner surfaces of Therefore, the outer peripheral surfaces of both the upper and lower insert members (78) and (79) are close to or in contact with the inner surfaces of both the flange portions (22) and the lower ends of the web portions (23) of the first and second fixtures (21A) and (21B). are doing. The edges of the upper bracket (81) and the lower bracket (82) on the pillar (2) side have a concave arc shape and are close to or in contact with the outer peripheral surface of the pillar (2). The rattling of the outrigger (7) is suppressed.

The procedure for attaching the outrigger (7) to the column (2) is the same as the procedure for attaching the outrigger (7) of the mobile scaffold (1) to the column (2) shown in FIGS. 5 to 8.

FIG. 13 shows a modification of the upper insert member and the lower insert member used in the attachment structure of the outrigger (7) to the movable scaffold (1) shown in FIGS. 11 and 12.

In FIG. 13, both the upper and lower insert members (85) and (86) are wedge-shaped and are press-fitted into the pocket holes (24) of the first and second fixtures (21A) and (21B), and are inserted into the support column (2). It is brought into pressure contact with the outer peripheral surface and the web portions (23) of the first and second fixtures (21A) (21B). This suppresses rattling of the outriggers (7).

In addition, when using both the upper and lower insert members (85) and (86) shown in FIG. Or, they do not need to be in a concave arc shape so that they touch each other.

The structure for attaching outriggers to columns according to the present invention is suitably used when attaching outriggers to columns of movable scaffolds or columns for temporary scaffolds that cannot stand on their own.
