 In FIG. 1, reference numeral 1 is a short hanger as a support, and the hanger 1 is hung from a ceiling by a suspension bolt 2 and arranged horizontally. Such a hanger 1 has the same height. A plurality of them are provided (only one is shown in the figure). A channel material is used for each of the hangers 1 as shown in FIGS. The hanger 1 as the channel material has a wide back portion 3, a pair of side wall portions 4 standing on both widthwise end portions of the back portion 3, and a widthwise inward direction from the tip of each side wall portion 4. Each hanger 1 has a surface portion 5 and a hanging portion 6 that hangs slightly from the inner end of each surface portion 5. The hanger 1 is provided with both hanging portions 6 in the extending direction of the hanger 1. A groove 7 is formed so as to extend, and an edge portion on the opening side of the groove 7 is constituted by the lower end of the hanging portion 6.

A cable rack 8 is mounted on the hanger 1, as shown in FIG. The cable rack 8 is arranged horizontally, and the cable rack 8 is composed of a linear member 9 as a pair of extending members and a plurality of girder members 10. The pair of linear members 9 extend in parallel at regular intervals. A channel material is used for each of the straight members 9, and therefore each straight member 9 has a back portion 11, a pair of side wall portions 12, and a surface portion 13 as in the case of the hanger 1. I have it. The plurality of beam members 10 connect the pair of linear members 9 at predetermined intervals in the extending direction of the pair of linear members 9, and each of the beam members 10 is also a channel member.

As shown in FIGS. 1 to 3, the hangers 1 and the cable rack 8 are fixed by a cable rack fixing tool (hereinafter, referred to as a fixing tool) 15. Each of the fixtures 15 includes a laying portion 16, a hook portion 17, a locking claw 18, and a screw tool 19.

The along portion 16 is formed of a steel plate so as to form a short flat surface. The extension length (the vertical length in FIGS. 2 and 3) of the alignment portion 16 is substantially the same as the width direction (the vertical direction in FIGS. 2 and 3) of the straight member 9, and The width of the alignment portion 16 is substantially the same as the width of the hanger 1 in the width direction.

The hooking portion 17 is one end side (the upper end side in FIGS. 2 and 3) in the extending direction of the laying portion 16 and is in the plate thickness direction of the laying portion 16 (left and right in FIG. 3). (Direction) on one side, the hook portion 17 is formed in a substantially hook shape, and the hook portion 17 is formed on one side in the width direction of the straight member 9 on the side wall portion 12 and the surface portion 13 as shown in FIG. Can be covered.

As shown in FIGS. 2 and 3, the locking claw 18 is provided on the side of the aligning portion 16 at the other end side (the lower end side in FIGS. 2 and 3) of the extending direction of the aligning portion 16. A pair is arranged along the other side plate surface in the plate thickness direction. Each of the locking claws 18 has a claw portion 20 that is locked to the hanging portion 6 of the hanger 1, and each of the locking claws 18 has an end portion in the width direction of the aligning portion 16. The claw portions 20 are rotatably supported (inserted) on the support pins 21 (for example, screws) provided at the respective ends so as to project outward to the other end in the extending direction of the aligning portion 16. As a result, the claw portions 20 of the respective locking claws 18 are displaced in the width direction of the aligning portion 16 due to the swinging of the respective locking claws 18, and the distance between the claw portions 20 of the both locking claws 18 is increased. It is supposed to be adjustable. In addition, in this embodiment, in order to make the pair of locking claws 18 interlock with each other, the pair of locking claws 18 are fixed by using a screw 22 and a nut (nut is not shown). While supporting the rotatable relative to each other, the insertion hole of each locking claw 18 through which the support pin 21 is inserted is formed into an arc shape as shown in FIG. 2 so that each locking claw 18 can be swung (with respect to the support pin 21). The relative movement of the locking claw 18 is possible). In this case, the screws 22, nuts and the like move up and down as the locking claws 18 swing, but at that time, in order to avoid interference between the screws 22 and nuts and the alignment portion 16, The notch 23 is formed in the along portion 16 so as to extend from the other end in the extending direction of the along portion 16 to one end side in the extending direction of the along portion 16.

The screw tool 19 is screwed into the hook portion 17 from the outside of one end side in the extending direction of the aligning portion 16. The tip end of the screw tool 19 is directed toward the other end side in the extending direction of the guide portion 16, and the tip end thereof is closer to the other end side than the hooking portion 17 in the extending direction of the guide portion 16. When the screw tool 19 is screwed in, it can be displaced in the extending direction of the aligning portion 16.

Next, a method of using the fixture 15 will be described. When fixing the cable rack 8 to each hanger 1, after mounting the cable rack 8 on the hanger 1, first, the hook portion 17 of the fixture 15 is attached to one side of the straight member 9 in the width direction ( 2 and 3, the upper part). Next, the pair of locking claws 18 are swung so as to be drawn inward in the width direction of the aligning portion 16, and in this state, the pair of locking claws 18 are inserted into the groove 7 of the hanger 1. Then, after the entry, the pair of locking claws 18 is swung again so as to be expanded, and the pair of locking claws 18 is brought into a locking standby state with respect to both side edges of the groove 7 opening of the hanger 1. Next, when the screw tool 19 is screwed in, the screw tool 19 pushes the side wall portion 12 on one side in the width direction of the straight member 9, and as a result, the main fixing tool 15 moves in the screwing direction of the screw tool 19 with respect to the straight member 9. Is relatively displaced in the opposite direction, that is, upward in this embodiment, and the pair of locking claws 18 are locked to both side edges of the groove 7 opening of the hanger 1. As a result, the screw tool 19 presses the linear member 9 against the hanger 1, and the linear member 9 is fixed to the hanger 1. Such a fixing operation is also performed on the other straight member 9, and the cable rack 8 is fixed to the hanger 1 via the pair of straight members 9.

Therefore, unlike the conventional case, it is not necessary to insert the bolt into the bolt insertion hole of the backing plate of the fixture and then insert the bolt into the bolt insertion hole of the bottom of the hanger (channel material). Since the work of screwing the nut onto the bolt can be eliminated, it becomes possible to extremely easily fix the cable rack to the hanger as a support.

Although the embodiments have been described above, the present invention includes the following. One locking claw 18 is used, and the locking claw 18 is locked to one of the edge portions on the opening side of the groove 7. Providing a plurality of screw tools 19.
