Abstract (en)
[origin: CA2674706A1] Disclosed is a method for continuously producing switch ties which differ from one another with respect to the length thereof and the mounting positi on of rail fastenings. Said method comprises the following steps: - one or m ore 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 b e produced, or at least one tie mold is used which is adapted to the geometr y of the switch tie to be produced; - bracing bars (5) are inserted as a rei nforcement; - the bracing bars are simultaneously tightened in an automatic manner by means of pairs of spindles, each bracing bar being individually ti ghtened; - concrete is filled into the tie mold (4); - the switch tie (11) i s allowed to set; - the switch tie is removed from the mold.
