- the geometry of the bracket corresponds to an open rectangle.
- a continuous, so uninterrupted section of the bracket runs below the sill.
- the concrete sleepers are supported for positionally accurate pouring into an in-situ concrete on support feet, the widths of which is slightly less than the extension of below the threshold extending portion of the reinforcement.

- a two-block concrete sleeper can also be found in DE-C-198 16 407.
- the reinforcement consists of so-called lattice girders with three longitudinal bars forming the edges of a triangular prism and two meandering serpents connecting them. Due to the construction of the reinforcement, different lattice girders must be used depending on the moment of resistance to be achieved, so that a corresponding storage of different reinforcements is required.

- the shorter base leg of the N-square pillar having the trapezoidal geometry may be partially removed and run within the concrete sleeper.
- the longer base leg extends below the sole of the concrete sleeper.
- the invention is also distinguished by the fact that the reinforcement consists of two trapezoidal bodies running parallel to one another, each of which forms an N-square column.

- Corresponding shorter sleepers usually have lengths between 80 cm and 140 cm and are connected in the track with a long sleeper. So that the monoblock stress-relieving sleepers can be produced cost-effectively, a section-possibly also a plurality of sections-of a structural steel mat, which is also referred to as a reinforcing steel mesh, is preferably bent into a column of desired geometry as a reinforcement.

- the reinforcing steel mat 150 consists of intersecting longitudinal bars 152, 154, 156, 158 and transverse bars welded thereto, two of which are identified by the reference numerals 160 and 162 by way of example. If, in the exemplary embodiment, the longitudinal and transverse rods 152, 154, 156, 158 or 160, 162 are arranged relative to one another in such a way that they describe a right angle, other geometries are also possible. In that regard, reference is made to conventional structural steel mesh or Baustahlgewebe and their geometries. The same applies to the steel and the bar diameter.
- the reinforcing steel mat 150 is then bent along the lines 164, 166, 168, 170 such that a trapezoidal geometry results, as the sectional view of FIG. 18 illustrates.
- the corresponding reinforcement designated by the reference numeral 172 has a geometry of a square column.

- a corresponding monoblock tension concrete sleeper 174 is shown with a reinforcement in section, which corresponds to that of FIG.
- tension wires are drawn.
- the reinforcement 172 is provided with an extension comprising the longer base leg 176 of the trapezoid.
- Section 178 extends below the bottom of the concrete sleeper 174 to serve as a support for further longitudinal bars 182, 184. If two are shown in the drawing, the number may differ. Of course, there is also the possibility that no further longitudinal rod is introduced.
- the longitudinal bars 182, 184 can be inserted or suspended, as illustrated in principle in FIG. 18.
- the anchoring ability of the threshold 174 in a slab track can be easily adapted, in particular, to the concrete used.
- the additional longitudinal bars 182, 184 also increase the resistance moment of the threshold 176 for handling thereof, thus avoiding the risk of damage, and in particular bending, of the reinforcement 172 in its exposed portion 178 during transport.

- the reinforcing 12 forming bent structural steel mat or Baustahlgewebe is open below the concrete sleeper 10, thus forming no closed in section rectangle. Rather, there is a U-geometry, wherein the side legs 26, 28 angled or bent inward (edge portions 14, 16). The edge portions 14, 16 thus form with the side legs 26, 28 a V or hook geometry.
- the side legs 22, 24 are connected via a function of a bracket performing another portion 30 of a structural steel mat, wherein the portion 30 has at least two longitudinal bars 32, 33 welded with transverse bars 37, which are thus part of the section of the structural steel mat.
- further longitudinal bars 34, 35 can be inserted.
- the section 30 may also be referred to as a reinforcement section.
- the longitudinal bars 34, 35 may have a dimensioning, such as the longitudinal bars 32, 33 welded firmly to the transverse bars 37, without, however, limiting the invention.

Independently of this go from the transverse leg 52 longitudinal rods 55, 57, which are welded to the transverse leg 52.
- the reinforcement extends in the drawing to be taken exemplary embodiments viewed in the longitudinal direction within the concrete sleeper, does not penetrate their faces.
- the end faces of the reinforcement can be closed, for example, with a grid, in order to reduce or prevent cracking in the concrete sleeper.
- a concrete sleeper 66 have a reinforcement 68, which shows an open trapezoidal geometry.

- longitudinal bars 85, 87 are welded to the transverse rods 74, 76, which, as shown in FIG. 9, is located in the vertices of the trapezoid.
- the longitudinal rods 85, 87 are therefore part of the structural steel mat.
- Runs in the longitudinal direction of the concrete sleepers 10, 44, 66 each have a reinforcement, which may have a cuboid or trapezoidal shape, so according to the embodiment of FIGS. 10-12 also has the possibility in a concrete sleeper 88 two mutually parallel reinforcements 90, 92nd introduce, which can show a trapezoidal geometry in section, with longer base legs 94, 96 below the concrete sleeper 88, ie under the sole 99 runs.
- the base leg 94, 96 is preferably interrupted, that is not closed, as is apparent from the sectional views of FIGS. 11 and 12.
- the reinforcements 90, 92 In order to exclude when pouring the concrete sleeper 88 that the reinforcements 90, 92 are bent outwards, they can be fixed to each other below the concrete sleeper 88 via a bracket 98, a wire or a similar element. Independently of this, the base legs 94, 96 of the reinforcement 90, 92 which extend below the sole 99 form supports for further longitudinal bars 100, 102 in accordance with the previously described task.
- the reinforcements 12, 46, 68, 90, 92 are according to the invention sections of bent Baustahlgewebe or mats, so have the illustrated longitudinal and transverse bars preferably different dimensions. It is provided according to the embodiment of FIGS. 1 to 12 that the cross bars, which are exemplified in Figs. 1 - 9 by the reference numerals 22, 24, 74, 76, define planes perpendicular to the longitudinal axis of the respective Monoblockspannbetonschwelle 10th , 44, 66, 88 run.
