Abstract
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. The crosstie includes rail seats with a convex channeled formation that is mateable with an extending member of a faceplate wherein the railseat has a width less than the width of the faceplate, and a center of the face plate has a first distance from a center of the concrete element and a center of the rails seat has a second distance from the center of the concrete element, the first distance greater than the second distance.
Claims21
1-18. (canceled)
A device comprising:
- an internal structure having one or more reinforced, u-shaped steel plates, each steel plate having an associated first tensioning structure and second tensioning structure, the first tensioning structure and the second tensioning structure configured to be coupled to a tensioning apparatus to apply tension to a plurality of wires embedded in high strength concrete;
- a rail seat formed in the high strength concrete;
- a face plate assembly having an extending member configured to mate with the rail seat;
- and
- wherein the rail seat has a width less than a width of the face plate assembly and the face plate assembly is asymmetric relative to the rail seat.
