PROBLEM TO BE SOLVED: To provide a rail fastening device with screw shoulder, when laying a rail on a rail with wide bottom width in a replaceable manner, capable of easily installing the rail with wide bottom width without changing the embedding distance between embedded plugs with respect to a bearing body even when the space from the rail bottom to the embedded plug gets narrower while ensuring satisfactory screwing strength between a shoulder and a fastening bolt.SOLUTION: A rail fastening device 100 with screw shoulder includes a shoulder 120 which has a bolt screw hole 122 formed penetrating through a reinforcement boss part 125 which protrudes downward from a rail-side bottom 123d of the shoulder 120 and which engages with an opening 142 of an embedded plug 140 and a reinforcing extension part 126 which extends toward the rail from the rail-side bottom 123d of the shoulder 120 for supporting the reinforcement boss part 125.SELECTED DRAWING: Figure 1
【課題】広い底部幅のレールに交換敷設する場合にレール底部から埋込栓までのスペースが狭くなっても、支承体に対する埋込栓の埋込間隔を変えずに広い底部幅のレールを簡便に設置するとともにショルダーと締結ボルトとの螺合強度を充分に確保するねじ式ショルダー付きレール締結装置を提供すること。【解決手段】ショルダー１２０のボルト螺入孔１２２が、ショルダー１２０のレール側底部１２３ｄから下方へ突出して埋込栓１４０の開口部１４２に凹凸嵌合する補強用ボス部１２５と、ショルダー１２０のレール側底部１２３ｄからレール側へ張り出して補強用ボス部１２５を支持する補強用張り出し部１２６とを貫通して設けられているねじ式ショルダー付きレール締結装置１００。【選択図】図１
