摘要

In a prestressed-concrete sleeper - chiefly a points sleeper or points with small radii of curvature - the invention specifies a method by means of which anchorings for the rails can be produced by rail-fastening screws 14 after the sleeper consolidation. Continuous steel anchor plates 5 in which, through holes 3 bored retrospectively at a desired point in the concrete of the sleeper 1 for the rail-fastening screws 14, bores 6 corresponding to the thread 15 of the rail-fastening screws 14 are bored out and provided with a thread, are installed within defined disposition regions in the sleeper.
