PROBLEM TO BE SOLVED: To realize a girder deflection reduction device capable of reducing girder deflection of its bridge girder in response to a change in acting force to the bridge girder.SOLUTION: A girder deflection reduction device 100 reduces girder deflection of a bridge girder 20, by changing a height position of an end part 31 of a net-like member 30 by a height adjustment mechanism part 40, when the girder deflection of the bridge girder 20 increases by changing acting force to the bridge girder 20 from a traveling railroad, since the bridge girder 20 can be made not to cause natural vibration by the acting force from the traveling railroad, by adjusting a vertical spring constant Kv for supporting the bridge girder 20 by the net-like member 30 to a suitable value, by changing the height position of the end part 31 of the net-like member 30 by the height adjustment mechanism part 40.SELECTED DRAWING: Figure 1
【課題】橋桁への作用力の変化に対応して、その橋桁の桁たわみを低減することができる桁たわみ低減装置を実現する。【解決手段】桁たわみ低減装置１００は、高さ調整機構部４０によって綱状部材３０の端部３１の高さ位置を変更することにより、綱状部材３０が橋桁２０を支持する鉛直バネ定数Ｋｖを好適な値に調整し、走行する鉄道からの作用力によって橋桁２０が固有振動を起こさないようにすることができるので、走行する鉄道から橋桁２０への作用力が変化して橋桁２０の桁たわみが増大した場合には、高さ調整機構部４０によって綱状部材３０の端部３１の高さ位置を変更するようにして、橋桁２０の桁たわみを低減する。【選択図】図１
