Abstract

L'invention concerne des moyens de fixation (41) servant à fixer des rails de chemin de fer (21) sur des traverses (11) ou des voies ferrées. Les moyens de fixation selon l'invention comprennent une rampe en arc (83), un crapaud élastique (51) et un boulon d'ancrage (71) à axe longitudinal vertical. La rampe en arc (83) est centrée sur l'axe longitudinal du boulon d'ancrage, le crapaud élastique (51) étant placé de manière à tourner autour de l'axe longitudinal par rapport au boulon d'ancrage. Le crapaud élastique présente une branche (55) qui glisse sur la rampe en arc (83) lors de la rotation du crapaud élastique (51) d'une position de prémontage dans une position de montage, ainsi qu'un segment d'appui (56) qui est relié à la branche (55) et qui, après rotation du crapaud élastique (51) de la position de prémontage dans la position de montage, vient s'appuyer avec précontrainte sur le patin (24) du rail (21).
