Definitions

  • the invention relates to a fixed carriageway, with a concrete sleepers and rails having superimposed on a support layer track grid and dowels for anchoring the concrete sleepers on the support layer.
  • Such fixed carriageways have for some time been offered by the applicant under the name GETRAC (registered trademark). It is a fixed track with a ballastless superstructure, where the base course is usually asphalt. This roadway is characterized by a direct superimposition of the track grid on asphalt.
  • the concrete sleepers are anchored on the asphalt layer by means of dowels. During installation, sleepers are laid on the asphalt layer and permanently anchored elastically using the anchor stone made of high-strength special concrete.
  • the dowel stone is designed so that it can remove occurring track forces in the longitudinal and transverse direction in the asphalt layer.
  • the asphalt layer is produced in a similar way as in road construction, the laying takes place in several layers with an automatically steered high-performance paver. On a Schottertrag für or a hydraulically bound support layer, the bituminous support layer is applied.
  • a threshold with dowel stone and a method for producing a solid track with such a threshold is known from DE 102 30 740 A1 known.
  • the dowel stone serves as a connecting element between the threshold and the supporting layer, to the concrete sleeper has on its underside a recess in which the dowel is used about half its height. The lower half of the dowel is inserted in a recess in the base layer and potted with a filler.
  • a fixed carriageway threshold known as the GETRAC A3 fixed carriageway is known.
  • the concrete sleepers have a central area with reduced width, they are wide sleepers, which are arranged only a short distance from each other.
  • the cylindrical dowel is below the broad threshold on the one hand in a recess below the broad threshold and on the other hand in a Recess of the base layer placed and potted.
  • the recess in the asphalt base course is rectangular and projects laterally beyond the middle area of the threshold with reduced width in order to allow subsequent filling with the filler material.
  • the invention is therefore an object of the invention to provide a solid track, in which the manufacturing cost is reduced.
  • the concrete sleepers have arranged between rail mounts central area with reduced width, in which on both sides of the concrete sleeper mounted on the support layer dowel stone is arranged.
  • the invention is based on the recognition that the installation of a fixed track can be simplified by dowels are mounted laterally on the concrete sleeper. This eliminates the costly attachment of the dowel stone below the threshold, the dowel stone is partially disposed in a recess below the threshold and partially in a recess of the support layer.
  • the dowel brick is designed as a trapezoid, that is as a spatial trapezoid.
  • it is a symmetrical trapezoid, which can be used rotated by 180 °.
  • the dowel block is fixed on a flat surface of the support layer. Accordingly, eliminates the costly production of a recess in the support layer, which previously had to be made with high accuracy. Instead, the necessary fixation of the threshold on the support layer is achieved by the positive connection between the dowel and the threshold, wherein the dowel is fixed on the flat surface of the support layer.
  • the dowel stone is also fixed with an asphalt adhesive or a concrete adhesive.
  • the area of reduced width tapers towards the underside of the concrete sleeper.
  • the cross section of the reduced width area is thus smallest at the bottom of the concrete sleeper and increases toward the top of the concrete sleeper. This tapered shape allows the positive-locking arrangement a dowel to attach the threshold by means of the dowel on the support layer.
  • the concrete sleeper is designed as a monobloc concrete sleeper in prestressed concrete construction.
  • the concrete sleeper is thus designed as an integral prefabricated concrete element with prestressed reinforcement, which can be positioned in this state on the support layer.
  • the roadway according to the invention is particularly well suited for base courses designed as asphalt base course or concrete base course.
  • a further development of the invention provides that in the roadway according to the invention an intermediate layer is arranged on contact surfaces between dowel bricks and the region of reduced width of the concrete sleeper.
  • the intermediate layer may be made of an elastomer, a film or other compliant material, whereby stress peaks be mitigated. This prevents spikes leading to chipping on the concrete sleeper.
  • a screwing of the dowel block may be provided with the support layer in the fixed carriageway, this can be introduced into the support layer, a dowel into which a dowel stone penetrating anchor bolt is screwed.
  • the dowel brick is positively held between two adjacent concrete sleepers.
  • any thresholds can be used for the fixed track according to the invention, provided that the threshold has a central constriction.
  • fixed carriageway 1 consists essentially of concrete sleepers 2, which are designed as a monobloc sleepers in prestressed concrete construction and are arranged side by side at a small distance.
  • Each concrete sleeper 2 carries a pair of rails, rails 3 are fastened by means of rail fasteners 4 at the top of the concrete sleepers 2.
  • the concrete sleepers 2 and the rails 3 together form a track grid, which is supported on a support layer 5.
  • the support layer 5 is formed as an asphalt base course, but other embodiments are possible in which the support layer is formed as a concrete base layer.
  • each concrete sleeper has a region 6 of reduced width arranged between the rail supports, which tapers downwards, that is to say towards the underside of the concrete sleeper 2.
  • the dowel brick 7 has downwardly tapering side surfaces which are exactly adapted to the side surfaces of the region 6 with reduced width of the concrete sleeper 2. That is, the inclined edges of the dowel 7 and the reduced width portion 6 have the same inclination angle. Accordingly, there is a concrete threshold between the dowel 7 and the area 6 with reduced width Form fit that allows the transfer of forces.
  • Fig. 2 shows a section through the fixed lane 1. There you can see that the two side of the concrete sleeper 2 arranged dowels have a decreasing in the direction of the support layer 5 cross section through the positive connection movement of the concrete sleeper 2 is prevented. The concrete sleeper 2 is thus held positively between the dowels 7.
  • Fig. 3 is a sectional view showing the dowel 7 in an enlarged view. It can be seen there that the dowel brick 7 is fixed by means of an asphalt adhesive 8 on the support layer 5. In the contact area between the dowel block 7 and the area 6 with reduced width of the concrete sleeper 2, an intermediate layer 9 is arranged, which consists of an elastomer and reduces voltage spikes. As a result, chipping on the concrete sleeper 2 are avoided.
  • the Fig. 4 to 7 show a second embodiment of a dowel block 10, which tapers upwards differently than the dowel block 7 shown in the first embodiment.
  • the dowel block 10 has a trapezoidal cross-section, wherein the cross-sectional area tapers from the bottom to the top.
  • the dowel stone 10 is limited by six side surfaces, the top 11 of the dowel block 10 is formed by four surfaces having a low inclination, in the illustrated embodiment, the inclination is about 1%.
  • the inclination of the vertical surfaces in the illustrated embodiment is 10: 1.
  • the dowel 10 When installed, the dowel 10 is surrounded by an elastomer (not shown).
  • the Fig. 8, 9 and 10 show a fixed track 12, consisting of concrete sleepers 2, rails 3 and rail fasteners 4, which respectively correspond to those of the first embodiment. Between two adjacent concrete sleepers 2 each a dowel block 10 is arranged, whereby the concrete sleepers 2 are held on a support layer.
  • the fixed track 12 substantially corresponds to the fixed track 1 of the first embodiment, which in the Fig. 1 to 3 is shown.
