Definitions
- these supports can be problematic during certain maintenance operations of the tracks, especially when it is necessary to replace a worn or damaged rail. Indeed, in such a case, it is necessary to loosen the anchoring element to detach the elastic clip and thus release the rail support: and, in doing so, the support is free to move laterally of so that the transverse setting of the rail is lost and must be found and checked carefully when fixing the replacement rail.
- These supports thus lengthen the duration of the maintenance procedures, make them more complex, and can therefore lead to possible positioning errors.
- the base is made of plastic.
- the support 10 is formed mainly of a base 11 of plastic taking in cross section a general shape of U: it thus has a bottom surface of seat 12, flat and parallel to the slab 3, two side flanks 13, and a surface upper support 14, flat and parallel to the lower seat surface 12, provided in the recess of the U between the two lateral flanks 13.
- Each lateral flank 13 has a lateral wedging surface 15 directed towards the inside of the support 10: these two lateral wedging surfaces 15 extend vertically vis-à-vis one another and thus frame the upper support surface 14; the distance which separates them corresponds substantially, with a clearance close to the width of the shoe 2a of the rail 2.
