Definitions

  • the invention relates to a concrete sleeper system for track systems according to the preamble of claim 1.
  • Concrete sleepers are suitable rail supports for the railway superstructure both in ballast beds and on solid concrete or asphalt surfaces. On the one hand, they have the task of fixing the rails true to the track and, on the other hand, to give the rail track the necessary elasticity due to its relatively short bearing surface for the rails in the event of a rolling load. During operation, these sleepers are subjected to pressure, bending, torsion and transverse displacement. A full length of the underside of the sleeper ensures a good pressure distribution in the subsurface, especially with ballast beds.
  • Y sleepers can achieve a considerably better load distribution for a given nominal distance of the support points of the rails according to the distance between the usual rod-shaped concrete sleepers.
  • a smaller support distance would be desirable and / or a higher resistance to torsional fracture, since in the fork of the Y-sleeper, in the case of operational loading in the symmetry axis of the sleeper, an opposing moment load occurs.
  • Rail fastening (GB-PS 861473) is widespread, in which the rail foot is first fixed to a metal base plate by means of a steel spring and the metal base plate is fixed to the threshold by further clamping means.
  • the mass problem is met by a Y-shaped concrete tie, which saves approx. 20% of the concrete mass per unit length, with the same or better rail bearing.
  • the concrete sleeper according to the invention with two or more supports for the rail per sleeper end can be usefully used in particular in heavily loaded track sections such as light rail lines, high-speed lines, heavy-duty lines.
  • the fixed bearing element threshold must remain stable against torsion and bending fracture. According to the invention, this is achieved, on the one hand, by distributing the threshold load to three points at each threshold end and, on the other hand, by using known polymer concrete made of colloidal cement and 4-10% addition of polymers such as polyvinyl acetate.
  • a concrete threshold with chopped or layered GRP fibers could also be used.
  • the technological properties of these composites are considerably better than those of conventional concrete or prestressed concrete. If necessary, the particularly stressed parts of the threshold determined from a stress analysis can be stabilized from a mixture of the composite materials or by adding long-fiber carbon fibers or glass fibers.
  • This reinforcement technology has the advantage that electrically conductive material is avoided, which could generate disturbances in track current detection systems by induction or conduction (electrolyte formation in rainwater between the rail and the threshold or threshold reinforcement).
  • the threshold system can also be used to prevent the magnetic field of DC-powered vehicles from being influenced.
  • the new concrete cross sleepers can be connected to the ground using so-called Nelson anchors; this contributes to the stiffening of the threshold as a rail support.
  • the attachment point for the Nelson anchor could also be included in the reinforcement.
  • the cast-in dowels can also extend through to the underside of the threshold and be open at the bottom so that any penetrating electrolytes, such as rainwater etc., can drain off.
  • a metal base plate can first be arranged on the concrete sleeper, which in turn carries two resilient, insulated support elements made of preferably polyethylene or other environmentally resistant plastics. This results in a lower specific load on the threshold.
  • This type of support should be used in particular if the track bed is made of asphalt or concrete.
  • the plastic plates then have to simulate or adopt the elastic sinking behavior of a ballast bed so that the track has an overall elastic characteristic despite the relatively rigid rails and sleepers. This is important for a long service life and break resistance of the track system at the extremely prevailing summer / winter temperatures of approx. 230 K to 350 K (-43 ° C to + 77 ° C).
  • the known steel spring bracing of the rail foot with the metal base plate can be used.
  • the metal base plate can be pre-assembled at the factory so that no screwing tools are required when laying rails. This also prevents the rail from being braced with excessive screw torques.
  • the raised support surfaces on the sleeper end can be created particularly easily if the sleeper concrete casting mold is designed for each support in such a way that at each sleeper end two bumps which emerge from the later sleeper surface are formed. An elastic rail pad is then placed on these humps, if necessary under high load with the insertion of a metal intermediate plate.
  • the elastic rail underlay can also be designed as a continuous plate or molded body, each covering two humps located at a sleeper end, with lateral guides for fixing the position on the sleeper or the hump. If this plate is elastic enough, nothing changes in the three-point bracing of the rail foot on the threshold.
  • Two adjacent rod-shaped threshold ends 1 of concrete cross sleepers made of polymer concrete have wedge surfaces 14 with an inclination of 1:40 to the center of the track (FIG. 1).
  • Bearings 3, 4, 5, 6 made of resilient, electrically insulating plastic plates for the rail foot 13 of the rail 2 are arranged on the wedge surfaces 14.
  • the center distance between the supports 4 and 5 is 600 mm, between the supports 3 and 4 or 5 and 6 170 mm.
  • the rail foot 13 is fixed in the center between the supports 3, 4 and 5, 6 by guide plates 7 and clamping brackets 8 resting in the groove 16 and the screws 9 inserted in dowels 17 (FIG. 2).
  • a slot 10 is provided for receiving a Nelson anchor 12, which is braced against the mounting surface 11 with the nut 15 via the washer 23.
  • the Nelson anchor 12 has previously been welded to a strip steel 21 cast in the asphalt bed 22 by means of a stud welding device, not shown.
  • Fig. 3 shows a section through a concrete cross sleeper two different reinforcement techniques and screw dowel trusses.
  • a cross member 18 made of GRP is cast into the sleeper end 1 for the rail fastening on both sides and thus secures a critical point of the sleeper against breaking out.
  • an end 1 of a concrete threshold is shown, which encloses a reinforcement cross member 20, the webs 19 of which consist of glass fiber laminates, which are laminated to the dowels 17 made of polyethylene, extend lengthwise through the entire threshold and in arm 24 with a hole for the Nelson anchor, not shown, end.
