Claims (5)
- 橋梁の主桁の側面に突設した所定厚みのフランジの孔から橋台に挿入して橋台に対する主桁の水平向きの振動を抑制する鋼棒を主体とする橋梁の緩衝機能付き地震時変位抑制装置において、フランジの孔に相応する位置に位置決め材を固定するとともに、ゴムの成形品からなる弾性体リングを鋼棒の上から孔の中で位置決め材に当接するまで挿入し、弾性体リングの上から孔の径よりも大きい座金を介して弾性体リングをナットで締め付けて鋼棒に固定したことを特徴とする橋梁の緩衝機能付き地震時変位抑制装置。
- 位置決め材がゴム弾性体の外径よりも小さい径の位置決めリングを鋼棒に固着したものである請求項1の橋梁の緩衝機能付き地震時変位抑制装置。
- 弾性体リングの底面に凹型ポケットを形成し、位置決めリングを凹型ポケットに底面をほぼ面一にして嵌入したものである請求項2の橋梁の緩衝機能付き地震時変位抑制装置。
- 弾性体リングが繊維入りのもので、繊維がゴムと積層されており、繊維が縦横の二軸又はそれ以上の多軸のものである請求項1〜3いずれかの橋梁の緩衝機能付き地震時変位抑制装置。
- 鋼棒と弾性体リングとを接着剤で接着した請求項1〜4いずれかの橋梁の緩衝機能付き地震時変位抑制装置。
