<P>PROBLEM TO BE SOLVED: To smoothly remove part of a coupling tool without causing breakage while turning the tool with its one end as an axis after a cover device of wiring and a tubing is embedded in concrete, in the cover device of the wiring and the tubing material in which the part of the coupling tool that connects protection tubes of the wirings and the tubing materials inwardly protrudes. <P>SOLUTION: The cover device of the wiring and the tubing material comprises a cover body 11 that is embedded in a concrete body 42 and coupled with the cable protection tube 41, and the coupling tool 31 that couples the cable protection tube 41 to the cover body 11. The cover body 11 has an installation hole 16 in which the coupling tool 31 is installed so that its one end side inwardly protrudes, and an interference protection space 17 that prevents the interference of the installation hole 16 and a tip angular part 35a of the protrusion 35 of the coupling tool 31, at the upper part of the protrusion 35 of the coupling tool 31 in the installation hole 16, in order to remove the cover body 11 from the concrete body 42 by turning the one end 24 after the cover device is embedded in the concrete. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
