PURPOSE:To surely prevent concrete from being infiltrated into embedded material, by providing an opening section set at a cover main-unit with a separable separation unit, and by providing the separation unit with a fitting section recessed from a mold-butted surface and for fixing a mold at the embedded material. CONSTITUTION:The cover main-unit 10 of a covering member 1 is provided with an opening section, and the section is provided with a separation unit 11 so that the unit 11 may be separably connected to the opening section with a thin section 13 or the like. Besides, at the separation unit 11, a section 15 recessed from a surface butted to a mold 40 is formed, and at the recessed section 15, a fitting section 12 for fitting a pulling-nearer member 3 is contrived to be set. After the covering member 1 is combined with piping embedded- material (a box) 2, the member 1 is placed in the mold 40. Besides, penetrating the mold 40, the pulling-nearer member 3 is fitted on the fitting section 12, and the embedded material 2 is fixed. In this state, concrete 50 is cast and hardened, and after the mold 40 is removed, the separation unit 11 is separated. |
