Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for mounting a supported body on one side of a plate by using a through hole of the plate.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 9 and 10, a conduit tube has been attached to a flange 2 or the like of a shaped steel 1 erected on a ceiling or wall of a building, factory, warehouse, station building or the like. ,
For supporting a supported body 3 such as a cable or an illuminator,
The substantially U-shaped fixing metal fitting 10 is used.

The fixing metal fitting 10 is, as shown in FIG.
A first arm portion 11 composed of both side plates 11b and 11b which are substantially parallel to the flat plate 11a, and side plates 12b which are connected to the first arm portion 11 at one longitudinal end thereof and which are substantially parallel to the curved plate 12a, 12b is an arc-shaped connecting portion 12 and a sawtooth side plate that is continuous from one end of the connecting portion 12 so as to face the first arm portion 11 and be substantially parallel to each other, and is parallel to the flat plate 13a. A second arm portion 13 composed of 13b and 13b, and a first arm portion 11 and a second arm portion 13
The opening 14 is formed on the front end side of each of the above-mentioned "."

A tap screw hole 15 is formed in the flat plate 11a of the first arm portion 11, and a fastening bolt 16 is screwed into the tap screw hole 15. Connection part 1 of mounting bracket 10
Circular through holes 5 and 6 for mounting clips 4 for mounting the supported body 3 are provided on the second flat plate 12a and the second flat plate 13a of the second arm portion 13, respectively.

Therefore, as shown in FIG. 10, the flange 2 of the shaped steel 1 is inserted from the opening 14 toward the connecting portion 12, and the fastening bolt 16 is rotated to move the flange 2 into the second arm portion 1.
3 sawtooth side plates 13b, 13b sawtooth portion 13b ',
13b 'and the tip of the shaft portion 16a of the fastening bolt 16 are clamped and pinched, so that the fixing bracket 10 is fixed to the flange 2.
After mounting, the two clips 4 for supporting the supported body 3 are attached to the circular through hole 6 of the flat plate 13a of the second arm portion 13.
Alternatively, it is attached to the circular through hole 5 of the flat plate 12a of the connecting portion 12.

However, the fixing metal fitting 10 having such a structure
For attaching the upper end of the hanging bolt to the circular through hole 6 of the second arm 13, for example, a first nut (not shown) is screwed in the vicinity of the upper end of the hanging bolt 3A in advance, and the hanging bolt is attached. The upper end of 3A is inserted upward from the lower side of the through hole 6, and a second nut (not shown) is screwed from the upper end of the hanging bolt 3A. Since the upper end of the hanging bolt 3A is attached to the fixing metal fitting 10 by tightening the nut and the fixing metal fitting 10 must be fixed to the flange 2 with the hanging bolt attached, this fixing work becomes extremely troublesome. Further, since the distance between the flat plate portion 13a of the second arm portion 13 of the fixing bracket 10 and the lower surface of the flange 2 is small, the upper end portion of the hanging bolt 3A is fixed to the flat plate portion 13
The installation becomes unstable because it can be inserted only a short distance from a.

For this reason, conventionally, a tap screw hole (not shown) is formed in the flat plate portion 13a of the second arm portion 13 so that the hanging bolt 3A can be retrofitted after the fixing metal fitting 10 is fixed to the flange 2 or the like. A fixing bracket (not shown) dedicated to the hanging bolt, which is provided and screwed with the upper end of the hanging bolt 3A into the tapped screw hole so that it can be attached later, or as shown in FIG. A fixing metal fitting 20 for a hanging bolt, which is provided with a special T-shaped notch 21 including a rectangular hole 21A and a slit 21B, is formed from the flat plate 12a of the connecting portion 12 to the flat plate 13a of the second arm portion 13. Two ear pieces 23, 23 at the tip of the support 22
Is inserted inward from the rectangular hole 21A and moved along the slit 21B so that the support body 22 supports the upper end of the hanging bolt 3A. Alternatively, as shown in FIG. Using a fixing bracket 24 for exclusive use of a hanging bolt, in which a special keyhole-shaped hole 25A is provided on the flat plate portion 13a, the two locking bodies 27, 27 at the tip of a dedicated support body 26 are used.
Is inserted inward from this hole 25A, and the upper end of the hanging bolt 3A is screwed into the support 26 so that the upper end of the hanging bolt 3A is
Two locking bodies 2 are inserted between the two locking bodies 27, 27.
7 and 27 are opened and locked to the hole edge of the hole 25A (Japanese Patent Laid-Open No. 8-74375).

[0008]

However, although these conventional techniques are convenient because the hanging bolts can be retrofitted to the fixing brackets, in any of these conventional techniques, a fixing bracket as a dedicated product must be prepared. In addition, since general-purpose mounting hardware cannot be used, the cost is extremely high.
