本発明によれば、レールの通り調整量の確保のため、タイプレート（８，１１）側に鋸歯状の形状（８Ａ′，１１Ａ′）と溝付座金（１５）の下部側面の鋸歯状の形状（１５Ｃ）を任意にずらし、また、溝付座金（１５）の底面の正十二角形状（１５Ａ）と両ねじボルト（１) に設けられたフランジ（１Ａ) の正六角形状（１Ｂ）を組み合わせることでスタッドボルトの回転を拘束しつつ、目標とするレール位置調整量を確保するようにした。 According to the present invention, in order to ensure the street adjustment amount of rail tie (8, 11) side in a sawtooth shape (8A ', 11A') and the lower side surface of the grooved washer (15) serrated The shape (15C) is arbitrarily shifted, and the regular dodecagonal shape (15A) of the bottom surface of the grooved washer (15 ) and the regular hexagonal shape (1B ) of the flange (1A) provided on both screw bolts (1) ), The target rail position adjustment amount is secured while restraining the rotation of the stud bolt.
上記したように、本発明のレール締結装置では、図１（ｂ）、図３（ｂ）、図５（ｉ）、図５（ｊ）に示すように、溝付座金１５とタイプレート８，１１の双方に鋸歯状の形状が設けられており、この組み合わせを任意にずらすことにより、タイプレート８，１１の位置の微調整を行うことができる。
As described above, in the rail fastening device of the present invention, as shown in FIGS. 1 (b), 3 (b), 5 (i), and 5 (j), the
また、図５（ｊ）に示すように、タイプレートと溝付座金（１５）に設けられた鋸歯状の形状（８Ａ′）と鋸歯状の形状（１５Ｃ）は、上下並列に並んでいる。 Further, as shown in FIG. 5 (j), the serrated shape (8A ') and the serrated shape (15C) provided on the tie plate and the grooved washer (15) are arranged in parallel in the vertical direction.
図６は本発明の実施例を示す溝付座金（調整座金）を反転させて細やかなレールの左右調整の様子を示す図である。 FIG. 6 is a view showing a state of fine left-right adjustment of the rail by reversing the grooved washer (adjustment washer) according to the embodiment of the present invention.
この図に示すように、溝付座金及びタイプレートの双方で鋸歯状の形状をその山・谷の位置が上下対称となるように設定しており、例えば、溝付座金の鋸歯状の形状（１５Ｃ）をそのまま左右いずれか一山分ずらした場合のタイプレート移動量（＝山のピッチに相当）に対し、溝付座金を１８０度反転すると山と谷の位置が反転し、その結果タイプレートの移動量は山のピッチの半分となる。 As shown in this figure, both the grooved washer and the tie plate have a serrated shape so that the positions of the peaks and valleys are vertically symmetrical. For example, the serrated shape of the grooved washer ( 15C) with respect to the tie plate movement amount (= corresponding to the pitch of the ridge) when it is shifted by one left or right as it is, when the grooved washer is turned 180 degrees, the position of the ridge and valley is reversed, and as a result, the tie plate The amount of movement is half the pitch of the mountain.
このように、鋸歯状の形状の設定をすることにより、タイプレートの移動量で微調整が可能となり、タイプレートに締結されたレールの位置の微調整を行うことができる。 Thus, by setting the sawtooth shape, fine adjustment is possible by the amount of movement of the tie plate, and fine adjustment of the position of the rail fastened to the tie plate can be performed.
したがって、既存のレール締結装置と比較して、大きなレール位置調整量を確保しつつ、その調整を容易にしたことで、軌道の保守管理の省力化に寄与し鉄道事業者の保守コスト低減に資する。 Therefore, compared with the existing rail fastening device, the large rail position adjustment amount is secured and the adjustment is facilitated, which contributes to labor saving of track maintenance management and contributes to the reduction of maintenance costs of railway operators. .
