A substructure is proposed for a continuously elastically supported rail vehicle track. Both the rails (1) which form the track are braced on their lateral faces below the rail head by means of elastic spacers (3) against the inner lateral faces of a frame comprising two frame halves (4, 5). A concrete plate (2) extends lengthways underneath each rail (1). The invention lies in the fact that: one frame half (4) is braced against a first side wall (6L) of a trough (6); the other frame half (5) is braced against the second side wall (6R) of the trough (6) by a wedge (7); the wedge (7) can be tightened by screws (8); and the concrete plate (2) is produced using concrete mixed in situ.

L'invention concerne une infrastructure de voie reposant sur un support élastique continu et destinée à des véhicules sur rails. Les deux rails (1) formant la voie s'appuient par leurs surfaces de délimitation latérales situées sous le champignon du rail, par l'intermédiaire de pièces d'écartement élastiques (3), contre les surfaces de délimitation latérales intérieures d'un cadre comprenant deux moitiés (4, 5). Une plaque longitudinale en béton (2) est placée sous chaque rail. L'invention est caractérisée en ce qu'une moitié de cadre (4) s'appuie contre une première paroi latérale (6L) d'un bac (6), en ce que l'autre moitié de cadre (5) s'appuie au moyen d'une cale (7) contre la seconde paroi latérale (6R) du bac (6), en ce que la cale (7) peut être serrée par des vis (8), et en ce que la plaque en béton (2) est fabriquée au moyen de béton coulé sur place.
