Abstract
A two-block concrete railroad tie for a fixed rail carriageway with an at least partially continuous reinforcement, which is exposed between the blocks and, after alignment, engages the sealing compound over a supporting layer, becoming anchored in it, the blocks being provided with a mounting surface, which is shortened in the longitudinal direction and from which slanting side surfaces extend upward at least at the front side.
Claims16
A railroad tie for a fixed rail carriageway;
- comprising:
- two concrete blocks spaced apart from one another in a longitudinal direction of the railroad tie, each of said blocks having an inner side and an outer side whereby said inner sides of said blocks are opposite one another, and each of said blocks having a lower mounting surface, a first outer side surface which extends upward from said lower mounting surface and outward in a direction away from said inner side and a second, inwardly inclined outer side surface adjoining said first outer side surface;
- and
- a reinforcement system for connecting and reinforcing said blocks, said reinforcement system passing entirely through each of said blocks such that said reinforcement system extends beyond said blocks,
- said reinforcement system extending at least partially through said first outer side surface.
