BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting device for mounting a safety rope or the like used when a safety rope is stretched on a structural member such as a beam, a purlin, or a scaffold at a construction site.

[0002]

2. Description of the Related Art When working at a high place, a safety rope is stretched along a walking path of the worker to ensure the safety of the worker. In the roof construction work of the building shown in FIG. 4, etc., columns 2 ... are erected at appropriate places of the structural member 1 which is the I-shaped steel as the main building material, and ropes such as ropes 3 are attached to these columns 2. When an operator moves on the structural member 1, the rope 3 is used as a handrail to prevent a fall accident or the like.

Conventionally, as shown in FIG. 5, a mounting device A for erecting the support column 2 on the structural member 1 has been generally used . This mounting device A has a structure in which a columnar fastener 5 having a split shape is fixed to the U-shaped metal fitting 4, and a tightening bolt 6 is provided on the U-shaped metal fitting 4. When mounting the attachment device A on the structural member 1 made of I-shaped steel, the U-shaped metal fitting 4 is fitted into the flange 1a of the structural member and the tightening bolt 6 is tightened. Further, when fixing the support column 2 to the attachment device A, the support column fastening tool 5 in which the support column 2 is fitted is bolted.
The nut 7 is configured to be tightened.

[0004]

[Problems to be solved by the device ] However, as mentioned above
In the conventional general mounting device A having such a structure,
If the bolts / nuts 7 to be tightened loosen for some reason or if the tightening force is insufficient , there is not only a risk that the support columns 2 will slide down, but when fixing the support columns 2 the bolts / nuts 7 should be supported while supporting the support columns 2 by hand. You are forced to do the difficult and dangerous work of tightening. Further, in order to mount the support column 2 without wobbling, as shown in FIG.
It is necessary to fix the two positions of the column 2 with the mounting devices A, A respectively mounted on the upper and lower flanges 1a, 1b of the shaped steel,
Moreover, since it is necessary to perform the work from above the structural member 1 at a high place, especially when the mounting device A is mounted on the lower flange 1b of the structural member 1 or the support column 2 is fixed to the mounting device A. In addition, it is extremely dangerous for the worker to lean over the structural member 1 and tighten the tightening bolts 6 and the bolts / nuts 7 below the upper surface of the structural member 1, which is extremely dangerous. In addition, it was troublesome that many bolts had to be tightened.
