- ベースプレート上に筒体を固定し、この筒体内に、下端がベースプレート上に支持され、筒体から突出する上端で構造物を支持する荷重支持軸を配置し、この荷重支持軸をベースプレート及び構造物に対して直立状態から傾動可能とし、上記筒体内に荷重支持軸を直立状態に保持するための弾性部材を設けた免震装置において、
上記ベースプレートと筒体をコンクリート基礎の内部に、筒体が起立してその上端がコンクリート基礎の上面で開口するように埋設し、
上記荷重支持軸は、円軸状で上下端面がベースプレートと構造物間で直立状態に起立するよう軸線と直角の平坦面に形成され、
この荷重支持軸の上下端部に、上下面が外側に向けて互いに接近する逆傾斜面となる傾動許容ブロックがそれぞれ外嵌固定され、
上記ベースプレート上に、下端の傾動許容ブロックを傾動可能で上下の移動を拘束する下部抱持金具を設け、
上記荷重支持軸の上端に載る構造物側プレートの下面に、上端の傾動許容ブロックを傾動可能で上下の移動を拘束する上部抱持金具を設けたことを特徴とする免震装置。
