High strength, integrally pre-stressed monoblock concrete crosstie with optimal geometry for use in ballasted railways

摘要

A monoblock concrete crosstie for railway tracks that achieves a high performance in operation includes a steel structure that is formed from ultra-resistant high strength steel plates embedded in a concrete element and having pre-stressed cold rolled wires with ends that form button head knots which are anchored to the steel plates. A faceted geometry allows optimal material usage and in turn increases the crosstie-ballast interlocking and stability with respect to the support surface.
