SHEATH PIPE AND INSTALLATION STRUCTURE OF COLUMNAR BODY
To provide a sheath pipe that is attachable and detachable but can prevent removal of a lid body by mischief, and an installation structure of a columnar body using the sheath pipe.SOLUTION: In the sheath pipe provided with a bottomed cylindrical main body cylinder and a cover body pivoted on a shaft part of the main body cylinder to open and close an opening part, a fastening member is attached to the cover body, and the cover body can be removed from the shaft part by releasing the fastening, the fastening member can be removed from the cover body in a state in which the cover body blocks the opening part of the main body cylinder, and the fastening member cannot be removed from the cover body in a state where the columnar body can be inserted into the main body cylinder. Since the fastening member is provided so as not to be removed from the cover body in a state in which the columnar body can be inserted into the main body cylinder, it is very difficult to remove the cover body from the sheath pipe used by installing the columnar body such as a car stop, and it is possible to prevent removal of the cover body due to mischief or the like.SELECTED DRAWING: Figure 6
【課題】着脱可能であるが、いたずらによる蓋体の取り外しを抑制できる鞘管と、これを用いた柱状体の設置構造を提供する。【解決手段】有底筒状の本体筒と、この本体筒の軸部に枢支させて前記開口部の開閉を行う蓋体とを備える鞘管において、前記蓋体に締結部材を取り付けて、この締結を解除することで蓋体を前記軸部から取り外し可能とし、前記蓋体が前記本体筒の開口部を塞ぐ状態において前記締結部材を蓋体から取り外し可能とし、前記本体筒の内側へ柱状体を挿入可能な状態において前記締結部材を蓋体から取り外し不能とする。前記本体筒の内側へ柱状体を挿入可能な状態において前記締結部材を蓋体から取り外し不能に設けるので、車止め等の柱状体を設置して利用している鞘管からの蓋体の取り外しが非常に困難なものとなされ、いたずら等による蓋体の取り外しを抑制できる。【選択図】 図６
