| description | To provide a composite sleeper provided with a recessed part for housing a rail conversion device.SOLUTION: A composite sleeper 16 consists of an electrically insulating fiber-reinforced plastic 51 and has a recessed part 25 for housing a rail changing device 15. The recessed part 25 has a bottom surface 60, a first inner surface 61 and a second inner surface 62. The horizontal cross section of each of a first side wall part 71 and a second side wall part 72 has a shape in which the thickness increases from an upper surface 20 toward the bottom surface 60. A first bottom surface arc part 91 is formed between the bottom surface 60 and the first inner surface 61. A second bottom surface arc part 92 is formed between the bottom surface 60 and the second inner surface 62. The radius of curvature of the cross section of the bottom surface arc parts 91, 92 along the vertical direction is larger than the radius of curvature of the first to fourth corner parts 81, 82, 83, 84.SELECTED DRAWING: Figure 1
【課題】レール転換装置を収容する凹部を備えた合成まくらぎを提供する。【解決手段】合成まくらぎ１６は電気絶縁性の繊維で強化された樹脂５１からなり、レール転換装置１５を収容する凹部２５を有している。凹部２５は、底面６０と、第１の内面６１と、第２の内面６２とを有している。第１の側壁部７１と第２の側壁部７２の水平方向に断面は、それぞれ、上面２０から底面６０に向かって厚さが増加する形状である。底面６０と第１の内面６１との間に第１の底面円弧部９１が形成されている。底面６０と第２の内面６２との間に第２の底面円弧部９２が形成されている。底面円弧部９１，９２の上下方向に沿う断面の曲率半径は、第１～第４のコーナー部８１，８２，８３，８４の曲率半径よりも大きい。【選択図】図１ |
