ANTI-VIBRATION SLEEPER AND ANTI-VIBRATION SLEEPER STRUCTURE
To provide an anti-vibration sleeper comprising an elastic member that can suppress fracture of the sleeper undergoing repeatedly loaded stress, and anti-vibration sleeper structure with fitting structure in which the sleeper is fitted into a recess in a concrete-made ballast.SOLUTION: The anti-vibration sleeper is provided that includes: a concrete-made body part, on the top surface of which rails are laid; and an anti-vibration part which is composed of elastic material and is fitted to both longitudinal ends of the body part. The anti-vibration part comprises: at least a bottom surface part which receives the bottom surface of the body part; and end surface parts and side surface parts which are each in contact with both side surfaces facing each other, of the body part. Both side surfaces facing each other, and the side surface parts of the body part include fitting structure intermittently arranged in a longitudinal direction. The anti-vibration sleeper structure has such a fitting structure that the body part and the ant-vibration part are fitted into a recess of the concrete-made ballast.SELECTED DRAWING: Figure 2
【課題】 繰り返し負荷される応力に対して破断を抑制できる弾性部材を備えた防振まくらぎ及びこれをコンクリート道床の凹部に嵌め込んだ嵌合構造を有する防振まくらぎ構造の提供。【解決手段】 上面にレールが敷設されるコンクリート製の本体部と、本体部の長手方向両端部に取り付けられる弾性材料からなる防振部と、を含む防振まくらぎである。防振部は、本体部の底面を受ける底面部と、本体部の対向する両側面にそれぞれ接触する端面部及び側面部と、を少なくとも備え、本体部の対向する両側面と防振部の側面部とは、長手方向に間欠的に配置された嵌合構造を有する。防振まくらぎ構造はかかる本体部及び防振部をコンクリート道床の凹部に嵌め込んだ嵌合構造を有する。【選択図】図２
