Disclosed is a method for continuously producing switch ties which differ from one another with respect to the length thereof and the mounting position of rail fastenings. Said method comprises the following steps: - one or more supporting metal sheets and/or one or more internal molds are mounted in a tie mold (1) according to the length and the shape of the switch tie to be produced, or at least one tie mold is used which is adapted to the geometry of the switch tie to be produced; - bracing bars (5) are inserted as a reinforcement; - the bracing bars are simultaneously tightened in an automatic manner by means of pairs of spindles, each bracing bar being individually tightened; - concrete is filled into the tie mold (4); - the switch tie (11) is allowed to set; - the switch tie is removed from the mold.
L'invention concerne un procédé de fabrication par rotation de traverses d'aiguille qui se différencient par leur longueur et la position de fixation des rails, ce procédé comprenant les opérations suivantes: fixer une ou plusieurs tôles d'écartement et/ou une ou plusieurs matrices internes dans un moule de traverse (1), en fonction de la longueur et de la forme de la traverse d'aiguille à réaliser, ou bien utiliser au moins un moule de traverse adapté à la géométrie de la traverse d'aiguille à réaliser; utiliser des barres de tension (5) comme armature; tendre simultanément et automatiquement les barres de tension au moyen de paires de broches, chaque barre de tension étant tendue séparément; remplir le moule de traverse (4) de béton; laisser durcir la traverse d'aiguille (1); démouler la traverse d'aiguille.
