PROBLEM TO BE SOLVED: To facilitate assembling works of overhanging scaffolds by providing a fitting part and a bracket part and providing a clamping screws and adjusting screws in the fitting part and providing a pair of connection pipes in the bracket part. ;SOLUTION: A fitting part 1 having a downward U-shape and a bracket part 2 horizontally stretched from the fitting part 1 to the outside direction of a protection wall, are formed in this prefabricated scaffold. The fitting part 1 is fitted downward from the upper end side of a protection wall, and clamp screws 5 fastening and fixing the fitting part 1 to the protection wall are provided at the sides 1a, 1b and further, an adjusting screw 8 is provided to adjust the fitting height of the fitting part 1 at the upper side 1c of the fitting part 1. And connection pipes 9 protruding upward are provided at the proximal end side and the distal end side of the bracket 2. A pair of front and rear columns of a vertical frame are connected and fixed through column joints between the connection pipes 9, 9. Accordingly, this scaffold structure can be adapted for the assembling of scaffolds for outside works in high rise building floors.;COPYRIGHT: (C)1999,JPO
