Description of the Related Art When performing various works such as steel construction work for construction, civil engineering work for roads, especially for fastening joints between steel frames at a position higher than the surface of the earth, welding work, etc. Various types of scaffolding devices for pillars have been proposed in the past.
Those disclosed in Japanese Patent Publication No. 1 and Japanese Utility Model Publication No. 3-2599 are known. FIG. 8 shows a scaffolding device for pillars disclosed in Japanese Utility Model Publication No. 3-7471, in which a pair of left and right pin fixing members 6 and push bolts 13 are preliminarily provided on vertical scaffolding mounting surfaces of a steel frame C for pillars. The pair of left and right pins 5 is attached to the upper and lower portions of the scaffold A for working in the widthwise central portion of the edge 1a of the stage 1 of the work scaffold A facing the pillar steel frame C via the pin attachment member 7. At the same time as mounting, a pair of left and right bracket members 8 each consisting of a reinforcing member 9, a vertical member 10 and a branch 11 are attached to the center of the lower surface of the stage 1, and the pins 5 are inserted into the sleeves of the pin fixing members 6 from above respectively. The vertical member 10 is brought into contact with the tip surface of the push bolt 13. The bracket member 8 secures the stability of the stage 1 by keeping the stage 1 horizontal and supporting the load when the column scaffold A is attached to the column steel frame C.
