POLYHEDRAL SLIDE BEARING DEVICE FOR STRUCTURE
To provide a polyhedral slide bearing device for a structure that can provide a stable seismic energy reduction effect against a low seismic intensity earthquake and a large brake against a huge earthquake.SOLUTION: A rotation absorbing elastic member 7 is disposed between an upper member 6 and a lower member 4, and has an upper connection steel plate 8 and a lower connection steel plate 9 integrated vertically. The upper member 6 or the lower member 4 is fixed to an upper structure side or a lower structure side. The upper connection steel plate 8 or the lower connection steel plate 9 of the rotation absorbing elastic member 7 is fixed to the fixed upper member 6 or the lower member 4. A first sliding surface 11 slidable horizontally omnidirectionally is formed between the unfixed upper member 6 or the lower member 4 which is in surface contact with the upper connection steel plate 8 or the lower connection steel plate 9 of the unfixed rotation absorbing elastic member 7. A second sliding surface 12 slidable horizontally omnidirectionally is formed between the unfixed upper member 6 or the lower member 4. The friction coefficients of the first sliding surface 11 and the second sliding surface 12 are set to be different.SELECTED DRAWING: Figure 1
【課題】低震度の地震に対する安定した地震エネルギー低減効果と巨大地震にたいしても大きなブレーキがかかる構造物用多面スライド支承装置の提供。【解決手段】上部部材６と下部部材４の間に配置されて、上下に上連結鋼板８、下連結鋼板９が一体化された回転吸収弾性部材７を備え、上部部材６又は下部部材４の一方を上部構造側又は下部構造側に固定し、固定された上部部材６又は下部部材４に回転吸収弾性部材７の上連結鋼板８又は下連結鋼板９を固定し、固定されない回転吸収弾性部材７の上連結鋼板８又は下連結鋼板９と面接触する固定されない上部部材６又は下部部材４との間に水平全方向スライド可能な第一スライド面１１を形成し、固定されていない上部部材６又は下部部材４と間に水平全方向スライド可能な第二スライド面１２を形成し、第一スライド面１１と第二スライド面１２の摩擦係数を異なるように設定する。【選択図】図１
