FIELD: railway transport; permanent way. SUBSTANCE: invention relates to methods of fastening rails to reinforced concrete base. Proposed anchor rail fastening contains anchor embedded in under-rail zone of reinforced concrete tie, two spring clamps coupling rail and anchor and rubber gasket placed under rail foot. Anchor is of combination design in form of anchor-linear provided with two T-shaped posts between which rail foot is placed, and two lock beads located at edges of shorter sides of anchor-linear. Spring clamps are made in form of rectangular section yokes connecting rail with anchor-liner by driving ends of yokes under flanges of T-shaped posts with subsequent pressing in at getting of yoke ends onto inclined surface of rail foot. Entire surface of anchor-liner in contact with tie concrete is coated with layer of dielectric in form of hardened epoxy-based resin, and rubber gasket, after molding and heat-and-moisture treatment of tie, is glue on anchor-linear. EFFECT: reduced number of parts used in rail fastening unit, dispensing with complex device for adjusting pressure of spring member of rail. 4 dwg |
