A belt 6 (FIG. 1) for holding and suspending the long member 2 is inserted through the square hole 10a.

In the present embodiment, the square hole 10a of the connecting member 15 is formed through the connecting member 15, and the square hole 10a of the mounting member 13 divides the mounting member 13 at the lower end of the square hole 10a. In the lower surface of the upper member 13A, along the left-right direction, a concave groove is formed upward, and the plate-like lower member 13B is screwed to form a square hole 10a. forming Incidentally, the square hole 10a of the mounting member 13 may also be formed so as to penetrate the mounting member 13. As shown in FIG.

The joining member 11 includes the above-described nut 5, a cut bolt 7 inserted through the pipe 4 provided on the pair of jig bodies 10 and having one end screwed to the nut 5, and a cut nut 7. It has an eye nut 8 screwed onto the other end of the bolt 7 and a locking nut 9 screwed together with the eye nut 8 onto the cut bolt 7 . An eye nut 8 and an anti-loosening nut 9 are screwed onto the other end of the threaded bolt 7 in advance.

In the method of holding the elongated member 2 using the hanging jig 1, the elongated member 2 placed on the floor and raised is arranged so as to sandwich the paired jig bodies 10 from both sides in the left-right direction. At this time, the ends 13a and 14a of the mounting member 13 and the opposing member 14 provided in the jig body 10 on the side opposite to the connecting member 15 are arranged to face each other.

Also, the upper surface of the mounting member 13 is brought into contact with the lower surface of the long member 2 . When the pair of jig bodies 10 are arranged to sandwich the long member 2 from both sides in the left-right direction, the pair of jig bodies 10 are arranged on the outer periphery of the long member 2 .

Next, the threaded bolt 7 to which the eye nut 8 is screwed is inserted through the pipe 4 in the through-holes 13c, 14c, 15b of the jig body 10 in which the nut 5 is not provided, and the two jigs are assembled. The main body 10 is passed through and screwed to the blind nut 5. - 特許庁By turning and tightening the annular portion 8a of the eye nut 8, the two jig bodies 10 are pulled together, and the elongated member 2 is clamped and held by the hanging jig 1 as shown in FIG. .

According to the suspension jig 1 of the present embodiment, the pair of jig bodies 10 sandwiching the long member 2 from both sides in the cross direction (horizontal direction) crossing the axial direction of the long member 2 are arranged in the lateral direction. The elongated member 2 can be held by joining with the joining member 11 that pulls and joins. At this time, since the pair of jig main bodies 10 are arranged on the outer periphery of the long member 2, it is possible to hold even a long member such as H-shaped steel that does not have a flange.

Also, the elongated member 2 can be easily held simply by joining the pair of jig bodies 10 with the joining member 11 . Therefore, it is possible to provide the hanging jig 1 which has a simple structure with a small number of constituent members and is inexpensive and easy to attach.

The joining member 11 is provided on one of the jig bodies 10 by passing a threaded bolt 7 having an eye nut 8 fixed by a locking nut 9 through the pair of jig bodies 10 in the left-right direction. Since the eye nut 5 is screwed together to join the pair of jig bodies 10, the pair of jig bodies 10 can be joined to hold the long member 2 simply by rotating the eye nut 8. , does not require tools for joining. Therefore, it is possible to easily hold the long member 2 by a simpler operation.

The elongated member 2 held by the hanging jig 1 is placed on the mounting members 13 of the pair of jig bodies 10 and supported in a stable state. 14 and connecting members 15 on both sides. Therefore, it is possible to hang the long member 2 in a more stable state.

In addition, since the center of gravity G of each jig body 10 is positioned below the center C in the vertical direction, the jig body 10 itself can maintain a more stable posture. Therefore, it is possible to hang the long member 2 in a more stable state. Further, when the elongated member 2 is held by the hanging jig 1, the elongated member 2 is placed on the mounting member 13. Therefore, for example, as shown in FIG. Since the center of gravity is lower when holding 20, it is possible to hold long member 20 in a more stable state.

In addition, since the jig main body 10 is provided with the cushioning material 3 at a portion facing the elongated member 2, when the jig main bodies 10 are pulled together in the left-right direction by the joint member 11 and joined together, Since the cushioning material 3 is interposed between the jig main body 10 and the elongated member 2, the jig main body 10 is prevented from contacting the elongated member 2 and being damaged when lifted, and is further strengthened. It becomes possible to hold the elongated member 2 .

Moreover, since the pair of jig bodies 10 have the same cross-sectional shape, they may be overlapped, or the other jig body 10 may be placed between the mounting member 13 and the facing member 14 of one jig body 10 . It is possible to arrange the mounting member 13 or the facing member 14 to accommodate them compactly.

In the above embodiment, the body frame 12 is made of wood, but it is not limited to this, and may be made of resin or metal. Moreover, in the above-described embodiment, the example in which the pair of jig bodies 10 are configured by the jig bodies 10 having the same cross-sectional shape has been described, but the present invention is not limited to this.

For example, one jig body has a placement portion, a facing portion, and a connecting portion and has a U-shaped cross section, and the other jig body is an open portion of the one jig body. It may be a flat plate-like jig main body that connects the mounting portion and the connecting portion on the side where the mounting portion is located.

Further, in the above-described embodiment, an example in which the joining member is composed of the blind nut 5, the threaded bolt 7, the eye nut 8, and the nut 9 has been described, but the present invention is not limited to this. For example, instead of the eye nut 8, a wing nut or the like may be used as long as the nut is provided with an operating portion that expands in the direction away from the shaft at the head of the bolt and can be gripped and tightened by the operator's fingers.

Also, instead of using the threaded bolt 7, a bolt having an operation portion such as an eye bolt or a butterfly bolt may be used. Also, a nut having an operation part such as an eye nut 8 or a wing nut may be used without using a blind nut.

In the above embodiment, as shown in FIG. 1, when the hanging jigs 1 are arranged at two positions on the long member 2 and hung by the belt 6, the jigs are arranged so that they can be used on either side. Although an example in which the square holes 10a are provided on both sides of the through holes 13c and 15b of the tool body 10 has been described, the square holes 10a do not necessarily have to be provided on both sides of the through holes 13c and 15b. I do not care.

Moreover, the above embodiments are intended to facilitate understanding of the present invention, and are not intended to limit and interpret the present invention. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof.
This embodiment includes at least the following inventions.
