Claims (2)
- 免震床に板バネを介して支持されるとともに、該板バネによって下方に付勢された上部すべり部材と、前記免震床の下方に配された下部構造に固設され、前記上部すべり部材から、所定の振動エネルギーが作用するとともに摩擦が切れる前記板バネによる付勢に応じた押付力で押圧される下部すべり部材とからなる剛すべり支承と、
水平の一方向に延び、前記下部構造に固設されたX軸レールと、該X軸レールに直交する水平の他方向に延び、前記免震床に固設されたY軸レールと、上端が前記Y軸レールに、下端が前記X軸レールにそれぞれ前記各レールに沿って進退自在に繋がる連結支持部材とからなるガイドレール支承と、
作用した振動エネルギーを吸収する減衰力及び前記免震床を元の位置に戻す復元力を発生させる減衰・復元機構とを備えることを特徴とする免震装置。 - 請求項1記載の免震装置において、
前記剛すべり支承が、上部すべり部材と前記下部すべり部材の間に介装され、上下に伸縮して前記板バネによる押圧力を調整するための伸縮部材を備え、
前記伸縮部材が、前記下部すべり部材上に置かれた状態で、上面がテーパー面とされた下側ブロックと、前記下側ブロックの上方に上下動可能に設けられ、下面がテーパー面とされた上側ブロックと、前記下側ブロックと前記上側ブロックの間に配され、左右に進退自在に設けられた楔状の滑動ブロックとを備えて構成されていることを特徴とする免震装置。
