MOBILITY LIMITATION DEVICE AND CONSTRUCTION METHOD OF MOBILITY LIMITATION DEVICE
PROBLEM TO BE SOLVED: To provide a mobility limitation device capable of following rotational movement of a bridge girder upon earthquake and capable of limiting movement of the bridge girder by means of a long steel member which can extend to effectively absorb the energy.SOLUTION: A mobility limitation device 100 is attached to a bridge abutment 10 and a bevel bridge girder 50 which is provided to a bridge seat 13 of the bridge abutment 10 to limit the movement of the bevel bridge girder 50. The mobility limitation device 100 includes: a long steel member 170; a bridge girder side hinge structure 110 which is provided to the bevel bridge girder 50 to rotatably connect the long steel member 170 to the bevel bridge girder 50; and a bridge abutment side hinge structure 130 which is provided to the bridge abutment 10 to rotatably connect the long steel member 170 to the bridge abutment 10.
【課題】橋桁の地震時の回転挙動に対して追随することが可能となり、長尺鋼材が伸びることで有効にエネルギーを吸収し、橋桁の移動を制限することが可能能な移動制限具を提供する。【解決手段】本発明に係る移動制限具１００は、橋台１０と、前記橋台１０の桁座１３上に設置される斜角橋桁５０とに取り付けられ、前記斜角橋桁５０が移動する際の移動を制限する移動制限具１００において、長尺鋼材１７０と、前記斜角橋桁５０側に設けられ、前記斜角橋桁５０と前記長尺鋼材１７０とを、回動可能に結合する橋桁側ヒンジ構造部１１０と、前記橋台１０側に設けられ、前記橋台１０と前記長尺鋼材１７０とを、回動可能に結合する橋台側ヒンジ構造部１３０と、からなることを特徴とする。【選択図】 図８
