Abstract
A biblock or multiblock transverse member is provided with concrete blocks which includes plates connected to each other with the aid of an incorporated reinforcement elements. The transverse member consists of many individual prefabricated blocks whose two reinforcement elements are interconnected, more particularly welded.
Claims8
Two-block or multi-block railroad tie which carry rail supports and which are connected to one another at an installation site, comprising:
- a plurality of prefabricated individual concrete blocks having longitudinally extending protruding reinforcement parts which are V-shaped, angled bar joists;
- said concrete blocks being spaced from one another at a desired spacing at said installation site by a gauge;
- said longitudinally extending protruding parts of longitudinally adjacent ones of said plurality of individual blocks being longitudinally aligned when said concrete blocks are spaced from one another at said desired spacing;
- and
- installation site provided welded connections that weld together said protruding reinforcement parts of longitudinally adjacent ones of said plurality of individual blocks to thereby form the two block or multiblock railroad tie in which said concrete blocks are spaced from one another at said desired spacing.
