RAILROAD TIE FASTENER
PROBLEM TO BE SOLVED: To provide a railroad tie fastener of which a fastening parts is rarely loosened, and capable of fastening a bridge girder and a railroad tie even when a bracing is spanned over a plurality of railroad ties, with the bracing fitted thereon.SOLUTION: A railroad tie fastener is for fixing a railroad tie (110) on a bridge girder (120). The railroad tie fastener includes: a hook member (10) having a long part bent in an inverted U-shape, and a first hook part (12) and a second hook part (13) provided respectively on two tip parts of the long part; and a spring body (20). The bridge girder (120) and the railroad tie (110) are fastened, when the railroad tie (110) is installed to intersect with the bridge girder (120), by having the long part cross over the railroad tie (110), the first hook part (12) hooked on the bridge girder (120) below one side of the railroad tie, the second hook part (13) hooked on the bridge girder (120) below the other side of the railroad tie, and the spring body (20) energize to separate a top surface of the railroad tie (110) from the long part.SELECTED DRAWING: Figure 2
【課題】締結部の緩みが生じにくく、複数の枕木に架け渡される継材があっても継材を付けたまま橋桁と枕木とを締結することのできる枕木締結具を提供する。【解決手段】橋桁（１２０）に枕木（１１０）を固定するための枕木締結具である。この枕木締結具は、逆Ｕ字状に曲がった長尺部、および、長尺部の２つの先端部にそれぞれ設けられた第１フック部（１２）と第２フック部（１３）を有するフック部材（１０）と、バネ体（２０）とを備え、橋桁（１２０）に交差するように設置された枕木（１１０）に対して、長尺部が枕木（１１０）を跨ぎ、第１フック部（１２）が枕木の片側の下方で橋桁（１２０）に引っかかり、第２フック部（１３）が枕木のもう片側の下方で橋桁（１２０）に引っかかり、バネ体（２０）が枕木（１１０）の上面と長尺部とを引き離すように付勢して橋桁（１２０）と枕木（１１０）とを固定するように構成されている。【選択図】図２
