BEARING DEVICE INSTALLATION METHOD AND BEARING DEVICE
PROBLEM TO BE SOLVED: To provide an installation method, which can temporarily placing a bearing device between a bridge girder and a bridge footing in a state where a shifting of the bridge girder in a bridge shaft direction is absorbed during installation construction and fix the bearing device between the bridge girder and the bridge footing by easily preventing a relative deviation movement in the bridge shaft direction between an upper shoe and a lower shoe after the temporary placement period, and a bearing device.SOLUTION: During an installation construction, a lower shoe 5 is fixed on a bridge footing 13 side, and an upper projection 8a of a side block 8 has a space S at both ends of a cutout part 4a of an upper shoe 4 in a bridge shaft direction and the upper shoe 4 is temporarily placed by fixing to the bridge footing 13 side. After a temporary placement period, a spacer 9 is inserted into spaces S1,S2 from outside in the direction perpendicular to the bridge shaft to stop a relative movement between the upper shoe 4 and the lower shoe 5 in the bridge shaft direction. The spacer 9 and the side block 8 are unified with a fixing bolt 10 that connects the spacer 9 to the upper projection 8a by penetrating the spacer 9 in the direction perpendicular to the bridge shaft from outside in the direction perpendicular to the bridge shaft.SELECTED DRAWING: Figure 5
【課題】据付施工中は橋桁の橋軸方向の変動を吸収する状態で支承装置を橋桁と橋脚の間に仮置きでき、仮置き期間経過後には上沓と下沓の相対的な橋軸方向のずれ移動を容易に阻止して橋桁と橋脚の間に固定できる据付方法および支承装置を提供する。【解決手段】据付施工中は、下沓５を橋脚１３側に固定し、サイドブロック８の上方突出部８ａが上沓４の切り欠き部４ａの橋軸方向両端とすき間Ｓを有する状態にして上沓４を橋桁１３側に固定して仮置き状態にし、仮置き期間の経過後には、橋軸直角方向外側からスペーサ９をすき間Ｓ１、Ｓ２に挿入して、上沓４と下沓５の相対的な橋軸方向の移動を阻止し、スペーサ９の橋軸直角方向外側からスペーサ９を橋軸直角方向に貫通して上方突出部８ａに連結する取付ボルト１０によって、スペーサ９とサイドブロック８とを一体化する。【選択図】図５
