DISPOSITIF DE POSITIONNEMENT ET DE FIXATION D'UN RAIL SUR UNE TRAVERSE

The subject of the present invention is a device for positioning and fixing at least one rail (17) on a sleeper (18) comprising: - two angle guides (9, 10) positioned in such a way as to clamp the rail (17) by a pincer effect, pressing against each of the axial edges of the foot of the rail (17), - a positioning sole (7) on the upper face of which the rail (17) and the angle guides (9, 10) are mounted, the sole (7) being intended to form an interface between the sleeper (18) and the elements mounted on the top face of the sole (7), - two retaining elements (19, 20) which are positioned on each side of the angle guides (9, 10) to keep these angle guides (9, 10) pressed against the edges of the foot of the rail (17), characterized in that the retaining elements (19, 20) and the sole (7) form one and the same single piece and in that, on the face thereof that is intended to press against the angle guides (9, 10) at least one of the retaining elements (19, 20) comprises an interaction surface suited to making it easier to insert a shim (15, 16) of the device between the retaining element (19, 20) and the corresponding angle guide (9, 10).
