PROBLEM TO BE SOLVED: To provide a bridge bearing device having a simple structure capable of reducing damage on an upper structure including a lower structure and a bearing device due to earthquake vibrations of level 2 or more, and capable of swiftly restoring the function of the bridge bearing device after the earthquake.SOLUTION: A bridge bearing device 1 which is disposed between an upper structure 3 and a lower structure 2 includes: a first coupler 10 formed with a female screw hole, which is coupled with an anchor bolt 9 embedded in the lower structure; a second coupler 11 which is disposed on the first coupler and formed with a female screw hole, and which has a rotating tool engaging part in an upper part thereof; a base plate 4 fixing an elastic bearing 5 formed with a hole for fixing bolt; and a fixed bolt 12 which is formed with a male screw inserted into a hole for fixed bolt formed in the base plate and screwed into the female screw hole of the first coupler and the second coupler and a notch 12b which is positioned at a position corresponding to a joint of the base plate and the second coupler and is set to endure the level 2 earthquake vibration and to be broken by earthquake vibrations greater than that.SELECTED DRAWING: Figure 1
【課題】構造が簡単でレベル２以上の地震動による下部構造と支承装置を含む上部構造の損害を軽減し、地震後の橋梁用支承装置の機能を素早く復元することが可能な橋梁用支承装置を提供する。【解決手段】上部構造３と下部構造２との間に配置される橋梁用支承装置１において、下部構造に埋設されたアンカーボルト９と連結され雌ネジ孔を形成した第１カプラー１０と、第１カプラーの上に配置され雌ネジ孔を形成し上端に回転工具係合部を有する第２カプラー１１と、弾性支承５を固定し固定ボルト用孔を形成したベースプレート４と、ベースプレートに形成した固定ボルト用孔に挿入され第１カプラー及び第２カプラーの雌ネジ孔に螺着される雄ネジが形成されベースプレートと第２カプラーの接合部に対応する位置にレベル２の地震動には耐えそれ以上の地震動で破断するように設定されたノッチ１２ｂを形成した固定ボルト１２とを備える。【選択図】図１
