The present invention relates to a technique for attaching a long body cover to a structure.

  As this type of long body cover, a straight tube type long body cover arranged at the straight portion of the long body arrangement route, an elbow type long body cover arranged at the corner portion of the long body arrangement route There are various types such as a T-shaped joint cover arranged at the junction or branching portion of the long body arrangement route, and a terminal cover arranged at the terminal of the long body arrangement route. Here, the end portions of the elbow-type long body cover, the joint cover, the terminal cover, and the like are configured to be fitted and connected in a state of being externally fitted to the end portion of the straight pipe-type long body cover.

  Then, these various long body covers are arranged at appropriate positions on the long body arrangement route to connect adjacent covers, and the long metal body attached to the structure side in a state of supporting the long body. By attaching the continuous body of the long body cover to the body support tool, the long body is covered with the continuous body of many long body covers over the entire area of the long body installation route. A body cover structure is constructed.

  By the way, conventionally, in order to attach the continuous body of the long body cover to the metal long body support attached to the structure side in a state of supporting the long body, Only the straight tube-type long body cover (an example of the long cover on the inner fitting side) arranged on the straight portion is attached to the long body support with the attachment.

  However, in the above-described conventional technology, the outer cover-side long body cover such as the elbow-type long body cover, the joint cover, or the terminal cover is merely fitted and connected to the inner fit-side long body cover. Therefore, when an external force is applied, etc., there is a possibility that the long cover on the outer fitting side may become glazed or the long cover on the outer fitting side may come off from the long cover on the inner fitting side. It was.

  The present invention has been made in view of the above-mentioned actual situation, and the main problem is that when an external force is applied, the long cover on the outer fitting side is glazed, or the outer fitting side is attached. The object of the present invention is to provide a long body cover mounting tool and a long body cover device that can effectively prevent the long body cover from being detached from the long body cover on the fitting side.
