TWO-BLOCK SLEEPER FOR RAILWAY
PROBLEM TO BE SOLVED: To provide a two-block sleeper for a railway with components having excellent electrical insulation properties that electrically insulates right and left rails readily and reliably for configuring a signal circuit, at the same time being light-weight, high in workability, manufactured at low costs and having high strength, in addition to having blocks with an elastic bottom surface that reduces an impact on ballast when a train passes.SOLUTION: Filler materials 2, 2, 2... having electrical insulation properties are used to fill a pair of left and right synthetic resin blocks 1,1 installed at intervals. The pair of blocks 1, 1 are connected with a steel connecting material 3. A first steel anchor material 5 welded on a bottom surface of a tie plate 4, and second and third steel anchor materials 7, 8 welded on a steel plate 6 fitted on a bottom surface of each of the blocks 1 are embedded when each of the blocks 1 is formed. The first to third anchor materials 5, 7, 8 are positionally separated from a connecting material part 30 embedded in each of the blocks. An elastic material 9 is bonded on a bottom surface of the steel plate 6.
【課題】 各部材の電気絶縁が極めて良好で、左右のレールを容易かつ確実に電気絶縁して信号回路を構成できるようにする。しかも軽量で作業性が良く、安価に製造でき、かつ強度が高い。各ブロック底面に弾性があり、列車通過の際、バラストへの衝撃を小さくする。【解決手段】 間隔をおいて設けた左右１対の合成樹脂製のブロック1、１に電気絶縁性を有する充填材２、２、２・・・を充填する。１対のブロック１、１を鋼製の繋ぎ材３で繋ぐ。タイプレート４の底面に溶着した第１の鋼製のアンカー材５と、各ブロック１の底面に取付けられる鋼板６に溶着した第２および第３の鋼製の各アンカー材７、８を各ブロック１の成形時に埋設する。しかも各第１・２・３のアンカー材５、７、８が各ブロックに埋設された繋ぎ材部分３０と位置的に離間している。鋼板６の底面に弾性材９を貼着してなる。【選択図】 図１
