Zusammenfassung: | The utility model relates to a steel rail and a fastener capable of preventing a steel rail from longitudinally creeping. The utility model which adopts a normal mode is connected with a rail sleeper. The utility model is characterized in that the contact surfaces of a steel rail and a fastener both adopt a concave-convex structure. When the technical proposal of the utility model is adopted, the steel rail and a spring strip pinch plate tally with each other, with tightness and enhancement of friction coefficient. Resistance force of the fastener is obviously larger than resistance force of a ballast bed in longitudinal direction; the steel rail and the rail sleeper are caused to fully connected with each other. The utility model has the advantages of enough capability of resisting a steel rail from bending and deforming, improvement of rigidity of a track panel, extension of the service life of a steel rail, guarantee of guarantee safety of railway trains, and labor, material resources, and fund saving. |
