【Example】

 1 to 3 illustrate the first embodiment.

In the present embodiment, a pair of front and rear standing portions are formed in a standing state above the front and rear plates in the upper right portion of the channel plate-shaped right holding body 2, and a taper edge is attached to the inner edge of the standing portion. It is formed as the contact portion 5. Further, on the upper portion of the right holding body 2, a supporting piece portion 10 which is a bottom portion of the fitting portion 7 is bent and formed on the front and rear plates in a erected state.

Further, a channel plate-shaped left holding body 3 is slidably fitted into the inside of the right holding body 2 in a superposed state, and a taper edge is similarly attached to the upper left portion of the left holding body 3. The contact portion 6 is formed to face the taper contact portion 5 in a V shape.

The guide elongated holes 11 are formed in both of the holding bodies 2 and 3, and the guide rods 12 are installed in a penetrating state in the guide elongated holes 11, and the holding bodies 2 and 3 are provided within the range of the guide elongated holes 11. 3 is slid to the left and right to adjust the facing distance between the tapered abutting portions 5 and 6. A U-shaped plate 13 is attached to the shaft mounting portion of the guide rod 12, and a nut hole 15 for screwing the suspension bolt rod 14 is provided in the bottom portion of the U-shaped plate 13 to hold the suspension bolt mounting portion 9 to the outer right side. It hangs in the center of part 2.

Further, in the embodiment, bolt mounting pieces 16 and 17 are provided at the right end portions of the right holding body 2 and the left holding body 3 to bridge the front and rear plates, and a fastening member is provided in a mounting hole of the bolt mounting piece 16. 8 is penetrated, a screw hole 18 is formed in the bolt mounting piece 17 of the left holding body 3, and the tightening bolt 8 is screwed into the screw hole 18.

Therefore, when the taper abutting portions 5 and 6 are widened and the fitting portion 7 is fitted on the hanging strip portion 1 and the tightening member 8 is screwed, the bolt mounting piece 16 is replaced by the bolt mounting piece 17. By being moved to the right side, the left holding body 3 inside the right holding body 2 moves to the right, and the interval between the taper abutting portions 5 and 6 is narrowed, and the fitting portion 7 is tightened and engaged with the depending strip portion 1. , It is fixedly attached to the hanging strip 1.

FIG. 4 illustrates a second embodiment.

In this embodiment, the left end of a channel plate-shaped engaging member 19 fitted from the lower side of the base 4 is pivotally attached to the left end of the base 4, and the front and rear plates of the right end of the engaging member 19 are attached. A bolt mounting plate 20 for closing the space is provided, a screw hole 21 is formed in this bolt mounting plate 20, and a tightening bolt 8 serving as a tightening member 8 is screwed into this screw hole 21. By pushing the right holding body 2 with the tip of the right holding body 2, the right holding body 2 is slid to narrow the gap between the taper abutting portions 5 and 6, and the taper abutting portions 5 and 6 are pressed against the hanging strip portion 1. is there.

[0015]

[Effect of device]

 Since the present invention is configured as described above, it can be easily fastened and fixed to the hanging strip portion of the ceiling member simply by turning the tightening bolt, and the tapering action of the left and right tapered side surfaces of the hanging strip portion is utilized. Since it is fastened, it will be possible to provide a hanging bolt mounting bracket with high fastening strength and high safety.

Further, since the structure is simple and the fastening bolts can be easily attached, mass productivity is excellent.

Further, according to the present invention, the engaging portion is configured by a C-shaped taper abutting portion whose facing distance can be varied by sliding to the left and right, and the taper abutting portion capable of adjusting the distance holds the hanging strip portion. As a result, it is possible to handle hanging strips of deck plates (ceiling members) that have several standard dimensions. That is, when fixing to hanging strips of different dimensions, simply adjust the screwing position of the tightening bolt to fit the fitting part to the hanging strip and tighten the tightening bolt. It is a versatile type hanging bolt mounting bracket that is extremely practical.
