コンクリート枕木(a)に締結されている。FIG. 5 shows a rail fastening device using this type of concrete sleepers. (A) is a concrete sleeper, (b) is a plug, (c) is a rail pad (d) on the sleeper (a). Rails (e) are spring clips composed of leaf springs, and the inner ends of the clips are rails (c).
The spring end curved portion (e '), which is pressed against the bottom of the clip and bent at the outer end of the clip, is fitted into the recess (b') formed on the outer side of the plug (b), and the spring clip ( e) and rail fastening inserted through a spring block curved portion (e ') of the clip (e) and a gauge block (f) interposed between the side edge of the bottom of the rail (c). Bolt (g)
The rail (c) is fastened to the concrete sleeper (a) by screwing and tightening on a plug (not shown) embedded in the concrete sleeper (a).

Since it is located lower than the lateral pressure acting line H ', when the rail lateral pressure is applied, as shown in FIG. 7, due to the moment balance condition, the outer rising portion (b ") of the receiving plug (b) is The gravity center position G of the reaction force distribution becomes lower than the lateral pressure acting position G ′,
The reaction force distribution is concentrated on the outer rising portion (b ″), and the reaction force P acts on the rail fastening bolt (g).
