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.

Claims (20)

1. 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.

2. The two-block or multi-block railroad tie of claim 1 , wherein equalizing pieces are disposed between the reinforcing parts.

3. The two-block or multi-block railroad tie of claim 1 , wherein:

the protruding reinforcing parts are, in each case, offset laterally in the individual block so that when the individual blocks are spaced from one another at said desired spacing, said laterally offset protruding reinforcement parts overlap one another; and

said welded connections being disposed between said overlapping protruding reinforcing parts.

4. The two-block or multi-block railroad tie of claim 1 , wherein:

each of the V-shaped, angled bar joists includes three longitudinal rods forming the edges of a triangular prism; and

said tie further includes two meandering coils connecting said V-shaped, angled bar joists.

5. The two-block or multi-block railroad tie of claim 4 , wherein the bar joists of each individual block are connected with one another by placed-down or pushed-in bar joist sections, which are welded together.

6. The two-block or multi-block railroad tie of claim 1 , wherein the reinforcing parts, braced with one another, protrude downward out of an only partly formed concreting of the individual blocks.

7. The two-block or multi-block railroad tie of claim 1 , wherein reinforcing rods of the reinforcing parts, which are spaced apart opposite one another, are connected to one another by mounted pipe sections.

8. Method for producing a two-block or multi-block railroad ties which are connected to one another at an installation site, comprising:

prefabricating a plurality of individual concrete blocks having longitudinally extending protruding reinforcement parts which are V-shaped, angled bar joists;

spacing said concrete blocks 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 connecting by welding together the protruding reinforcement parts of longitudinally adjacently aligned ones of the plural individual blocks at the installation site to thereby form said two block or multi-block railroad tie in which said concrete blocks arc spaced from one another at said desired spacing.
