SLIDE BASE ISOLATION MECHANISM
PROBLEM TO BE SOLVED: To provide a slide base isolation mechanism capable of effectively using an outer periphery space around a base-isolated floor and preventing damage to a constant load spring caused by an earthquake.SOLUTION: A slide base isolation mechanism 1A includes a base-isolated floor 3 configured slidably in a horizontal direction on a support part and having an opening 31A that penetrates the base-isolated floor in a vertical direction, and a restoration device 4 connecting a structural floor (support part) 11 with the base-isolated floor 3 and restoring a displacement of the base-isolated floor 3 relative to the structural floor 11. The restoration device 4 includes a constant load spring 42 disposed on the base-isolated floor 3 and a wire (connecting material)43 that connects the constant load spring 42 with an anchor bolt 12 disposed on the structural floor 11, and the wire 43 connects the anchor bolt 12 to a location inside the opening 31A.
【課題】免震床の外周のスペースを有効に活用できるとともに、地震の震動による定荷重ばねの損傷を防止することができる滑り免震機構を提供する。【解決手段】支持部上を水平方向に滑動可能に構成され上下方向に貫通する開口部３１Ａが形成された免震床３と、構造床（支持部）１１と免震床３とを連結し、免震床３の構造床１１に対する変位を復元可能な復元装置４と、を備える滑り免震機構１Ａにおいて、復元装置４は、免震床３に設置された定荷重ばね４２と、定荷重ばね４２と構造床１１に設置されたアンカーボルト１２とを連結するワイヤ（連結材）４３と、を有し、ワイヤ４３は、開口部３１Ａの内側においてアンカーボルト１２を連結している。【選択図】図１
