SEISMIC ISOLATION HANDRAIL
To solve a problem not to sufficiently meet an occurrence that a gap in a seismic isolation clearance part between a seismic isolation structure and a non seismic isolation structure in a seismic isolation handrail of a prior art with respect to a seismic isolation handrail becomes narrower than expected during an earthquake.SOLUTION: For a seismic isolation handrail installed between a seismic isolation structure and a non seismic isolation structure, the seismic isolation handrail 1 is configured by a handrail body 2 formed of extension members extendable in a length and cylindrical bodies 3, 4 fit to a circumference of the handrail body, wherein the cylindrical bodies 3, 4 are configured by at least two rigid cylindrical bodies, each of which is respectively separated to two independent bodies in such a way that the handrail body 2 is folded twice in a generally horizontal direction at a generally central portion in a longitudinal direction in a typical installation condition.SELECTED DRAWING: Figure 1-A
【課題】本発明は、免震手摺に関し、従来の免震手摺においては、免震構造物と非免震構造物との免震クリアランス部の間隔が、地震時において狭小スパンとなることに十分対応できていないことが課題であって、それを解決することである。【解決手段】免震構造物と非免震構造物との間に架設される免震手摺において、前記免震手摺は、長さが伸長する伸長部材で形成された手摺本体２と、該手摺本体の外周に被嵌された筒体３，４とで構成され、前記筒体３，４は、通常の架設状態での長手方向の略中心部から前記手摺本体２が略水平方向に二つ折れするように、別体にされた少なくとも二つの剛性な筒体で構成されている免震手摺１とする。【選択図】図１−Ａ
