It is comprised from the attachment tool 15 and the guard fence support | pillar 20 supported rotatably at the other end part of the supporting member 12. As shown in FIG.
The attachment 15 is in contact with a hanging piece 12a in which one end portion of the support member 12 is bent in an L shape, and both end edges thereof are slidably guided in a vertical direction by a pair of left and right guides 12b provided on the hanging piece 12a. The movable piece 16 and the first locking portion 17 are configured. The movable piece 16 is supported by a slide piece 16a guided by each guide 12b so as to be slidable in the vertical direction, and a drop-off preventing member 16b bent forward is provided at the upper part of the slide piece 16a. The movable piece 16 does not fall out between the guides 12b, and parts are not lost.
The first locking portion 17 is screwed into a screw hole 16c ′ formed in a bent piece 16c provided at the lower portion of the slide piece 16a, and a first shaft portion (screw rod) 17a that advances and retreats with respect to the lower surface of the support member 12. A first locking member 17b that is provided at the tip of the first shaft portion 17a and clamps the material to be attached to the lower surface of the support member 12 when the first locking portion 17 is fastened; and the first shaft portion 17a And a first head 17c provided at the other end.

On the other hand, the other end portion of the support member 12 has a column support piece 12c bent upward, and the guard fence column 20 is loosely fitted in a support hole 12d penetrating the column support piece 12c. One end of the fence post 20 bent in an L shape is provided with a screw portion 20a, and a fixing member 20b such as a nut is screwed to the screw portion 20a. The fixing member 20b such as a nut fixes the protective fence column 20 in an upright state, and prevents the protective fence column 20a from falling off the column support piece 12c when the protective fence column 20 is in the lying state shown in the figure. Further, the other end of the protective fence post 20 is provided with an annular lobe holding portion 20c for holding the protective fence rope.
FIG. 2 is a partially enlarged view of the protective fence column 20 in an upright state. By tightening the fixing member 20b while the protective fence column 20 is upright, the protective fence column 20 is aligned along the column support piece 12c. Can be fixed in an upright state. Therefore, by tightening or releasing the fixing member 20b, the protective fence column is configured to be displaceable between a standing state and a recumbent state.
FIG. 3 (a) is a diagram showing an overview of a base structure 30 made of L-shaped steel used in substation equipment and the like, and equipment 31 such as insulators provided on the structure, and FIG. 3 (b). These are figures which show the state at the time of utilizing a part of foundation structure which is the existing equipment shown to (a), and attaching the scaffold board support apparatus 10 and a scaffold board to the equipment.

The scaffold board support device according to one embodiment of the present invention constitutes an existing structure 30. For example, the scaffold board is supported on the upper surface of a horizontal case 32 a portion of an angle member (an angle steel having an L-shaped cross section) 32. The upper surface of the first locking member 17b contacts the lower surface of the case 32a by tightening the first system stopper 17 of the fixture 15 in a state where the lower surface of the device 10 on the side of the hanging piece 12a is in contact.
