GIRDER REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To realize a girder reinforcement structure capable of suitably reinforcing an existing girder.SOLUTION: A beam structure body 90 comprises: a pair of cantilever beam sections 10 fixed to a pair of cross beams (an edge cross beam 4 and an intermediary cross beam 5); intermediary beam sections 20 arranged between the cantilever beam sections 10; and connection sections 30 which connect edges of the cantilever beam sections 10 and the intermediary beam sections 20 respectively. Because the beam structure body 90 is arranged between the pair of cross beams (the edge cross beam 4 and the intermediary cross beam 5), a main girder 2 can be reinforced in a manner that enables the beam structure body 90 to support a load acting on the main girder 2. Also, a characteristic period of the main girder 2 can be reduced by increasing rigidity thereof with a reinforcement effect of the beam structure body 90 and thereby curbing, when a railroad track is laid on the main girder 2 for example, resonance of the main girder 2 associated with travel of a train on the track.SELECTED DRAWING: Figure 1
【課題】既設の桁を好適に補強することができる桁の補強構造を実現する。【解決手段】１対の横桁（端横桁４、中間横桁５）に固設されている１対の片持ち梁部１０と、その片持ち梁部１０の間に配設された中間梁部２０と、片持ち梁部１０と中間梁部２０の端部同士をそれぞれ接続した接続部３０とを備えた梁構造体９０が１対の横桁（端横桁４、中間横桁５）の間に設置されているので、その梁構造体９０によって主桁２にかかる荷重を支えるようにして、主桁２を補強することができる。特に、梁構造体９０を設置した補強によって主桁２の剛性を向上させて、その主桁２の固有周期を短くすることができるので、例えば、主桁２上に鉄道用の軌道が敷設されている場合、その軌道を列車が走行することに伴う主桁２の共振を抑制することができる。【選択図】図１
