BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a rod-shaped body suspending device according to the present invention. FIG.
1 shows a rod-shaped body hanging tool 10 according to an embodiment of the present invention. This rod-shaped body suspending tool 10 is composed of a holder 11 having a screw hole 11a formed in the axial direction inside a metal hexagonal columnar body from an end face thereof, and a hook 12 fixed to the holder 11. .

The hook 12 is formed of a metal rod bent in an inverted U-shape, and both end sides 12a and 12b of the holder 11 are arranged such that the bent portion, that is, the locking portion 12c is located on an extension of the center axis of the holder 11. And the opposite side 1
Adhered to 1d, 11c and fixed by means such as welding

When the bar-like body to be lifted and hung by the bar-like body lifting tool 10 is, for example, a reinforcing bar 13, a holder is provided at an end portion thereof as shown in FIG. A male screw portion 15 that can be screwed into the female screw portion 14 formed in the 11 screw hole 11a is formed.

When the reinforcing bar 13 is lifted by the bar-shaped hanging device 10 according to the present embodiment, the reinforcing bar 13 passes through the opening of the screw hole 11a formed in the end face of the holder 11 on the side where the locking portion 12c of the hook 12 is not located. The rebar ends are screwed into the screw holes 11a and attached to the holder 11.

Next, a rod-shaped body suspender 10 having an end screwed into a screw hole 11a of the holder 11 and a reinforcing bar 13 connected thereto.

c, for example, a lifting wire such as a crane (not shown)
Is lifted by locking or fastening.

Thus, the reinforcing bar 13 and the rod-shaped body suspender 10
Are rigidly connected to each other, which makes it difficult for suspension deflection and suspension displacement to occur. In addition, since the reinforcing bar 13 is suspended with its central axis oriented in the vertical direction, the stability during movement is extremely high, and the safety is high. Sex can be obtained.

The reinforcing bar 13 thus lifted
Is moved down to a desired place, for example, a built-in place, and is lowered. Thereafter, the lock between the lifting wire and the rod-shaped body hanging tool 10 is released, and further, the holder 11 is removed from the end of the reinforcing bar 13, and the rod-shaped The connection between the hanging member 10 and the reinforcing bar 13 is released, and the reinforcing bar is erected. By repeating this operation, a number of reinforcing bars 13 can be built.

In the rod-shaped body suspending tool 10 according to the embodiment of the present invention described above, the holder 11 is formed of a hexagonal column. However, the shape of the holder 11 is not the gist of the present invention, but is the shape of the suspended body. An end of a certain reinforcing bar 13 is attached, and the reinforcing bar 1 is fixed via a hook 12 fixed to the holder 11.
3 can be of any shape as long as it is well-balanced when suspended vertically.

Also, the shape of the hook 12 is the same as that of the holder 11, and in this embodiment, the metal rod is formed by bending an inverted U-shape. Alternatively, it may be a fishing hook type as long as it is a rigid metal rod or the like.
Further, in this embodiment, a screw hole 11a for attaching (screw-in) the reinforcing bar 13 to the holder 11 is formed so as to penetrate the holder 11, but its upper end face side is closed as seen in FIGS. It may be.
