To attach the scaffolding device of this invention to the steel beam 9, pull out the shoulder bolt 14, move its small diameter part 16 in the slot 13, narrow the crossing angle of the arm 6.6, and then tighten the upper end of the arm 6. After clamping both ends of the horizontal rib 10 with the clamps 8, the large diameter portion 15 of the bolt 14 that has been pulled out is pushed into the adjustment hole 12 at the intersection, and the nut 23 is tightened. Since the tightening is fixed between the washers 17, the screws 11, 11 can be tightened in this state.

The number of adjustment holes 12.12 is determined according to the rate of change in the intersection angle required for the hanging arm 6.6, and the pitch of each adjustment hole 12 is determined by the horizontal rib 10 held by the clamp 8.
It goes without saying that the design can be optimally determined depending on the type of width dimension, etc.

As explained in detail above, this invention eliminates the need to completely remove the bolts 14 from the intersection of the arms 6 and 6 each time the scaffolding device is attached to or removed from the steel beam, unlike the conventional method. In this way, there is no need to worry about the bolt donut that fixes the intersection being dropped or lost during installation or removal, and the bolt 14 can be attached to the arm simply by moving within the slot 13 via its small diameter portion 16. Since the intersection angle of 6.6 can be freely adjusted, alignment at the intersection of the adjustment holes 12 can be performed extremely easily.

Even if the arms 6.6 are not fixed at their intersections, the bolts 14 always keep them in an X-shaped crossing state, so when installing or removing the scaffolding device, the operator must hold the arms 6.
.. There is no need to hold the arm each time to prevent the scaffold from falling over, so even if the scaffolding device becomes larger, it can be installed and removed by a small number of workers.
Accidents caused by tilting of the arm 6.6 can be prevented.

Further, the intersection of the arm 6.6 is located at the large diameter portion 1 of the bolt 14.
5, it is strong, and since it is fixed to the horizontal ribs 10 of the steel beam in an X-shape, the support is extremely stable.It has many advantages compared to conventional ones. The arm 6.6 is highly functional and can be manufactured at a low cost.Moreover, the arm 6.6 is equipped with a stopper 20 having a pair of clamping portions 21. .6 can be prevented from being reduced in half by the slots 13, and therefore even if the weight of the scaffold is large, it can be held firmly and reliably, and in particular the connections at intersections can be made firmly. It can provide many excellent scaffolding devices, including the following advantages:
