<p>PURPOSE:To simplify a work to mount a filler falling-off preventing fixture on a structure by providing a pair of flange-form sleeve fixing members each having a contact part capable of making contact with the opening surface of the through hole of the structure and a sleeve positioning means to effect positioning in the radial direction of a through-sleeve in a through hole. CONSTITUTION:A through sleeve 5 and flange-form sleeve fixing members 7 are provided. The sleeve fixing members 7 are arranged on both sides in the direction of the thickness of the structure 1 in a state that the through sleeve 5 is arranged in the through hole 2 of the structure 1. The contact part 7b of the sleeve fixing member 7 is brought into the opening surface of the through hole, the lock part 7a of the sleeve fixing member 7 is fitted in a locked state externally of the through sleeve 5, and the through sleeve 5 is mounted on the structure 1A sleeve positioning means K, i.e., a resilient protrusion 10, to effect positioning in the radial direction of the through hole sleeve in the through hole is provided. The through-sleeve 5 is easily installed in a preset position in the radial direction of the through hole 2 in a manner to be positioned concentrically to the through hole 2.</p> |
