In order to perform the screwing operation in the state, the operation must be performed while holding the support tool by hand, and the operation is likely to be complicated. For example, in high-place work (particularly, overhead work), There is a problem that it is difficult to work and the efficiency becomes poor. Further, even when the mounting position is changed along the longitudinal direction (up and down direction) after the mounting on the suspension bolt, the screw must be removed and the operation must be performed. Therefore, there is a danger that the working efficiency is reduced throughout the whole work of supporting the long body.

In order to solve the above-mentioned problems, as a long body support tool, the locking portion is constituted by providing a hook portion which can be hooked to the hanging bolt 2 on the support body, and On the other hand, a method in which the hook portion is hung from the side and locked can be proposed. However, in the elongate body support according to this proposal, in a state where the elongate body is engaged with the suspension bolt, for example, a force in the axial direction acts on the supported elongate body or a force in the lifting direction acts on the elongate body. In this case, there is a risk that the hook portion is easily detached from the suspension bolt, the support tool itself falls, and stable support of the elongated body cannot be achieved.

Accordingly, an object of the present invention is to make it possible to easily and reliably carry out the work of attaching to a rod-shaped body, and to further remove the long-sized body which is hard to be detached from the rod-shaped body even when an external force acts on the rod-shaped body. To provide a body support.

Therefore, in addition to the locking claw of the pressing member and the locking of the rod-shaped body, the locking claw portion and the locking action of the rod-shaped body,
It is possible to securely mount the device in a state where it is harder to slip down.

According to the fourth aspect of the present invention, since the pressing member is provided with a releasing operation portion capable of releasing the urging of the rod-like body, the releasing operation portion allows the rod-like body to be released. It is possible to move the invention product along the longitudinal direction of the rod by releasing the pressing force of the invention.For example, after temporarily fixing the invention to the rod, the invention can be moved to a predetermined mounting height. It is possible to easily carry out the change of the mounting position, or to slide and remove the mounting position, thereby improving the workability of installation and removal.

According to the characteristic feature of the fifth aspect of the present invention, since the pressing member 11 is a leaf spring, the pressing member 11 can be brought into contact with the rod-like body and the engagement of the rod-like body into the hook portion can be increased. The function of elastically pressing and pressing can be performed by one leaf spring, and the pressing member can be formed without requiring a complicated mechanism, thereby increasing the cost of the entire elongate body support. Can be prevented.

Therefore, according to the elongated body support of the present invention,
Work such as attaching to a rod-like body and changing the attachment position can be performed easily and reliably. For example, even when working at a height higher than the position of the head, no effort is required, and a long body is efficiently used. Since the support operation and the mounting position changing operation can be performed, a speedy mounting operation can be realized. Furthermore, even when an external force acts on the rod-shaped body, the rod-shaped body is unlikely to be detached from the rod-shaped body, so that good locking performance on the rod-shaped body and, consequently, stable support performance of the long body can be exhibited. .
