The mounting holes 4a, 5a of the bracket 2 and the mounting holes 2a, 3a of the brackets 2, 3 are fitted to each other, and both mounting holes 4a,
5a, 2a, 3a, the bolt 25 is inserted, the nut 26
Fixed by. At this stage, the mounting member 4,
If the spacing of 5 is adjustable, that is, if one or both of the mounting members 4 and 5 are slidable, they can be mounted on columns of various sizes, and the mounting holes can be easily fitted.

Next, the pipe clamp 14 is fitted and fixed to the support rods 6 and 7, and the square pipes 12a and 13a of the side members of the scaffold frames 12 and 13 are fitted to the receiving portion 14a of the upper portion of the pipe clamp 14. Then, the holes 16 of the square pipes 12a and 13a and the holes 15 of the receiving portion 14a are fitted to each other, the bolt 17 is inserted, and the nut 18 is fixed.

After that, the hooks 11 at both ends of the scaffold plates 9 and 10 are locked to the round pipes 12b and 13b of the scaffold frames 12 and 13, respectively, and the handrails provided on the upper surfaces of the scaffold frames 12 and 13 are retained. The lower end of the handrail 21 is inserted into the receiver 22 and fixed by a bolt 23.

Further, the scaffolding plate 1 connected between the projecting portions at both ends of the scaffolding plates 9 and 10 attached as described above by a suitable method.
The scaffolding device of the present invention is completed when 9 and 20 are bridged and fixed. After that, the column 1 is lifted by a crane to stand upright and installed by welding or the like. Then, using the scaffold of the present invention, beam installation work between the columns 1 and the like are performed.

The scaffolding device attached as described above is disassembled and removed by providing a chain block 28 and the like on a beam 27 connected and installed as shown in FIG. 2, for example.
