PLASTIC DOWEL FOR FASTENING OF A RAIL AND COMBINATION OF SUCH A PLASTIC DOWEL AND A RAIL SCREW

摘要

The present invention relates to a plastic plug (1) for securing a rail on a solid base, said plug having a plug opening (3) for introducing a sleeper bolt (2), a plug internal space (8), a shank section (4) which connects to the plug opening (3) in the longitudinal direction LR of the plastic plug (1), and a holding section (5) which connects to the shank section (4) in the longitudinal direction LR of the plastic plug (1) and is provided on the outside with at least one projection (11) protruding in the radial direction R and running around the circumference. Cracks in the solid base near the surface are avoided by an upper flank (12) of the projection (11) associated with the plug opening (3) at an angle ß1 of 90° ± 3° in relation to the longitudinal axis L of the plastic plug (1).
