SEISMIC ISOLATION STRUCTURE
PROBLEM TO BE SOLVED: To provide a seismic isolation structure which can easily change a changeover displacement amount of an attenuation force in a displacement changeover-type oil damper according to a change of a situation.SOLUTION: In a seismic isolation structure in which a displacement changeover-type oil damper 6 is interposed between an upper structure and a lower structure, a cylinder 7 of the displacement changeover-type oil damper is fixed to either of the upper structure and the lower structure, and a piston rod 9 integrated with a piston 8 which is movably arranged in the cylinder, and extending from the cylinder is connected to the other of the upper structure and the lower structure. A detection part 16a in which step parts 17a changeable in heights are formed with intervals in a horizontal direction is attached to the piston rod 9 side so as to be changeable in a length dimension between the step parts, and a shut-off valve 15 engaged with the detection part 16a, and switching an attenuation force in front of and behind the step part is arranged at the cylinder 7 side so as to be displaceable in a vertical direction.SELECTED DRAWING: Figure 4
【課題】状況の変化に応じて容易に変位切替型オイルダンパーにおける減衰力の切り換え変位量を変更することができる免震構造を提供する。【解決手段】上下部構造間に変位切替型オイルダンパー６が介装された免震構造において、変位切替型オイルダンパーのシリンダー７が、上下部構造の一方に固定され、シリンダー内に移動自在に設けられたピストン８に一体化されてシリンダーからの延出するピストンロッド９が、上下部構造の他方に連結されるとともに、ピストンロッド９側に、水平方向に間隔をおいて高低が変化する段部１７ａが形成された検出部１６ａが、当該段部間の長さ寸法が変更可能に取り付けられるとともに、シリンダー７側に、検出部１６ａに係合するとともに段部の前後において減衰力を切り換えるシャットオフ弁１５が鉛直方向に変位自在に設けられている。【選択図】図４
