 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view of a portable auxiliary scaffold when the components of the present invention are connected and attached along the outer periphery of an electric pole, and FIG. 2 is a perspective view when the portable auxiliary scaffold is attached to an electric pole. 3 and 4 are a side view and a plan view of the band scaffold, and FIG. 5 is a rear view of the contact plate of the band scaffold. In FIG. 1, the band scaffold 1 is composed of a tread plate 2, an abutting plate 3 and a stay 4. The tread plate 2 and the abutting plate 3 form a right angle and are bent together with the stay 4 to form a right triangle. In addition, the end of the tread 2 is bent along the convex curved surface of the stay and is fixed to the end of the stay 4. Two ribs 2a are provided adjacent to each other on the upper surface of the tread to reinforce the tread and prevent the operator's foot from slipping. Round holes are formed in the contact plate 3 at four corners, and a chain with nuts is inserted therein. Further, a punching projection portion projects inward from the center of the contact plate 3, is bent at an acute angle on the lower side of the punching window, and is used for the hook 7. The stay 4 forms a curved surface having a convex cross-section in the longitudinal direction facing outward, which is useful for strength. A rubber plate 5 is attached to the back surface of the contact plate 3 shown in FIG. 5 in a shape avoiding the position of the round hole 6, and when attached to a utility pole as a mobile auxiliary scaffold, the outer surface of the utility pole and the contact plate. It has good frictional contact with 3 and is used as a non-slip material. FIG. 6 is a plan view of the small eggplant 13, and FIG. 7 is a plan view of the chain 14 with a nut. The nut-equipped chain 14 opens a part of a straight portion of an annular chain, one end of which is fitted with a nut, and the other end of which is fitted with a male screw which is screwed into a female screw inside the nut. The threaded portion can be screwed with the nut to form an annular chain. FIG. 8 is a plan view showing a chain state in which a plurality of chains are connected. To attach the portable auxiliary scaffold of the present invention to a utility pole, as shown in FIG. 1, a chain 14 with a nut is inserted into each of the round holes 6 of the abutment plate 3 of the band scaffold 1, and a plurality of chained chains (Fig. The chain with nut 14 is fitted into the ring of the chain located at both ends of the chain (1 in FIG. 1) from the opening, and the nut is screwed into the threaded portion, so that the chain is symmetrically formed on both sides of the contact plate. To be done. Next, another chain 14 with a nut is fitted into the chain 15 with the nut 14 through which the round hole 6 located at the upper left corner of the contact plate is inserted, and the chain 14 with a nut is further inserted into the small size through the opening of the chain 14 with the nut. After inserting the eggplant 13 into the ring portion, the nut is screwed to form an annular chain. Further, a plurality of chains 15 on the side connected to the nut-attached chain 14 inserted into the round hole 6 located at the upper right corner of the contact plate 3 are chained and extended to form a band shape. That is, the left end of the band-shaped chain with respect to the abutment plate 3 ends with the small cage 13, and the right end thereof ends with the normal chain 15. Therefore, when mounting on the utility pole, the band-shaped chain is hung on the bolt upper surface of the bolt scaffold 8 (Fig. 2) of the utility pole, and the contact plate 3 is attached to the outer peripheral surface in the longitudinal direction of the utility pole via the rubber plate 5. While being in contact with each other, it is rotated along the lateral direction of the outer circumference of the utility pole, and one piece of the chain 15 located on the right side of the band-shaped band according to the thickness of the utility pole and a small box arranged at the left end of the band. The attachment is completed by connecting 13 to the bolt scaffold 8 at a position where it can be easily attached by an operator, with a gap therebetween. As described above, the operator can start work on the pillar by placing one foot on the bolt scaffold 8 and the other foot on the tread 2 of the portable auxiliary scaffold according to the present invention. Since the chain can be attached to the lower part of the bolt scaffolding via the chain with nuts (not shown) due to its structure, there is no wobbling, and the rubber plate 5 attached to the back surface of the contact plate 3 prevents the chain from wobbling. It will not slip on the outer surface of the utility pole, ensuring stable work and safety.
