As shown in FIG. 3, the fast clip uses a W-type spring 300, and has been attempted to increase life of components against fatigue and reduce manufacturing, track-mounting and maintenance costs .
  • the fast clip which can be constructed in a complete mechanization, has various profits that all components can be preassembled to the cross tie and carried to an installation site and that the fast clip do not require disassembly and reassembly when it is set to a rod rail (as being disassembled and reassembled in the preassembled condition) .
  • the fastening device also has a disadvantage that it is decreased in safety because not having a double tilting prevention device.
  • the French type had used a two block reinforced concrete cross tie and the RN-type rail fastening device, which is a double elastic rail fastening device to be fastened to the reinforced concrete cross tie. Recently, as the French ' type, the Nabla type rail fastening device shown in FIG. 5 has been developed and used.
  • the Nabla type rail fastening device can have a two- tage elasticity by a two point contact, that can provide the uniform fastening force and increase a upward spring coefficient, by making a thin plate spring 400 upwardly convex in a longitudinal direction of the rail, tightening the thin plate spring and pressing the central convex part to be contacted to an upper portion of a nylon clip.
  • FIGS. 6 and 7. In Germany, a K-type rail fastening device had been used for a long time. Such rail fastening device adopts a fastening method that a tie plate is fastened on a wood cross tie and the rail is fastened through push metal means.

Abstract

L'invention concerne un dispositif de fixation des rails et un procédé de fixation qui permettent d'économiser des frais de gestion et d'assurer une sécurité renforcée grâce à un dispositif de sécurité double, sans utiliser de vis. Ce dispositif de fixation des rails occupe un espace réduit pour le travail de fixation, permet de diminuer les frais de gestion et assure une sécurité renforcée car le nombre de composants utilisés est réduit du fait de l'utilisation d'un épaulement et d'un ressort de fixation afin de réaliser le dispositif de sécurité double sans adopter le procédé de vissage. Ce dispositif de fixation des rails présente l'avantage de garantir un niveau de sécurité élevé même lorsque des accidents, tels qu'un rebond du ressort, surviennent pendant le travail de fixation, de faciliter le travail de fixation grâce à une voie de traction de ressort et de faire intervenir une faible contrainte sur le ressort. En outre, le travail de fixation de la voie de traction de ressort permet de minimiser la libération éventuelle du ressort sous l'effet d'une force extérieure puisque le ressort est fermement fixé par compression.
