BEARING REACTION FORCE ADJUSTMENT METHOD AND BEARING REACTION FORCE ADJUSTMENT SYSTEM
To provide a bearing reaction force adjustment method and bearing reaction force adjustment system for restoring the balance of reaction force in each bearing in a bridge in which the balance of reaction force in each bearing is unbalanced.SOLUTION: After lifting all the multiple jacks 12, jacking up each jack-up part 104A of an upper structure 101, and transferring the load received by the multiple bearings 106 to the multiple jacks 12, adjust the vertical movement amount of each jack 12 so that the values of the reaction forces of each jack 12 measured by the multiple reaction force measuring means 12A respectively become the predetermined reaction force values, and adjust the height position of each jack-up part 104A of the upper structure 101 where each jack 12 jacks up, and the height position of each jack-up part 104A of the superstructure 101 after the adjustment is measured by the corresponding displacement meter 16, and the height of each corresponding bearing 106 is adjusted based on the measurement result.SELECTED DRAWING: Figure 1
【課題】各支承における反力のバランスが崩れた橋梁において、各支承における反力のバランスを回復させる。【解決手段】複数のジャッキ１２を全て上昇させ、上部構造１０１の各ジャッキアップ部位１０４Ａをジャッキアップし、複数の支承１０６が受け持っていた荷重を複数のジャッキ１２に移し替えた後、複数の反力計測手段１２Ａがそれぞれ計測した各ジャッキ１２の反力の値がそれぞれ所定の反力値となるように各ジャッキ１２の上下方向の移動量を調整して、各ジャッキ１２がジャッキアップする上部構造１０１の各ジャッキアップ部位１０４Ａの高さ位置をそれぞれ調整し、その調整後の上部構造１０１の各ジャッキアップ部位１０４Ａの高さ位置をそれぞれ対応する変位計１６で計測し、その計測結果に基づき、対応する各支承１０６の高さを調整する。【選択図】図１
