CONSTRUCTION GIRDER INSTALLATION DEVICE AND CONSTRUCTION GIRDER INSTALLATION METHOD
PROBLEM TO BE SOLVED: To provide a construction girder installation device and a construction girder installation method capable of maintaining a track out of the track in a state in which a construction girder is installed, and which does not require track bed work during installation or removal of the construction girder.SOLUTION: A construction girder installation device 1 comprises: a support member 3, which includes an insert nut N2 which is buried under a sleeper M from the top surface of the sleeper M which exists on the outer side of a pair of rails R and fixed to the sleeper M, an overlapping part 4 positioned on top of the sleeper M, and an overhanging part 5 which supports a construction girder 2 and which extends outwards from a sleeper M top surface edge Ma and is positioned such that at least part of the construction girder 2 is further outward than the sleeper M top surface edge Ma; and a fastening bolt B2 which is attached to the insert nut N2 and which fixes the support member 3 to the sleeper M by pushing the overlapping part 4 towards the top surface of the sleeper M.SELECTED DRAWING: Figure 2
【課題】工事桁の設置および取り外しに際して道床作業が不要であり、工事桁を設置した状態で軌間外から軌道を整備することができる、工事桁取付装置および工事桁取付方法を提供する。【解決手段】工事桁取付装置１は、一対のレールＲの外側で既設のまくらぎＭの上面からまくらぎＭに埋め込まれ、まくらぎＭに固定されるインサートナットＮ２と、まくらぎＭの上に置かれる重なり部４と、まくらぎＭの上面の端Ｍａから外側に張り出し、工事桁２の少なくとも一部がまくらぎＭの上面の端Ｍａよりも外側に位置するように工事桁２を支持する張り出し部５と、を含む支持部材３と、インサートナットＮ２に取り付けられ、重なり部４をまくらぎＭの上面の方に押すことにより支持部材３をまくらぎＭに固定する締結ボルトＢ２とを備える。【選択図】図２
