BLOCKAGE TOOL
To provide a blockage tool capable of filling gaps necessary for fixing a cover, such as one installed on a road, with bolts.SOLUTION: A blockage tool of the present invention is a blockage tool for covering the side surfaces of a bolt with a polygonal head. The blockage tool of the present invention comprises: a washer part, which is a circular plate with a first hole; a protective part, which is a circular plate with a second hole; and a compression section, which is an elastic material with a third hole. The diameter of the first hole is larger than the diameter of the screw part of the bolt and smaller than the maximum diameter of the bolt's head. The diameter of the second hole is larger than the maximum diameter of the bolt's head. The diameter of the third hole is equal to or smaller than the diameter of the second hole. The compression section is sandwiched between the washer part and the protective part, such that at least the center of the second hole and the center of the third hole align. The sum of the thickness of the protective part's plate and the thickness of the elastic material in its uncompressed state is equal to the length of the bolt's head.SELECTED DRAWING: Figure 7
【課題】道路に設置するような蓋をボルトで固定する際に必要な隙間を塞ぐ。【解決手段】本発明の閉塞具は、頭部側面が多角形のボルトの頭部側面を覆うための閉塞具である。本発明の閉塞具は、第１の穴を有する円形の板であるワッシャ部と、第２の穴を有する円形の板である保護部と、第３の穴を有する円形の弾性材である圧縮部とを有する。第１の穴の径は、ボルトのネジ部の径より大きく、ボルトの頭部の最大径より小さい。第２の穴の径は、ボルトの頭部の最大径より大きい。第３の穴の径は、第２の穴の径以下である。圧縮部は、少なくとも第２の穴の中心と第３の穴の中心が一致するようにワッシャ部と保護部に挟まれている。保護部の板の厚さと、圧縮部に力を加えていない状態での弾性材の厚さの合計は、ボルトの頭部の長さと同じである。【選択図】図７
