Definitions

  • the invention relates to a method for producing a track track for rail vehicles, as used in particular for modern high-speed roads as a so-called fixed track.
  • a solid roadway is generally understood to mean a railway superstructure in which the ballast is replaced by another material, for example concrete or asphalt, which, in contrast to the ballast, is only slightly deformable.
  • Different types of structures are known for the fixed carriageway, for example embedded systems such as the Rheda type with its two modifications Rheda-Sengeberg and Rheda-Berlin or the systems Heitkamp and Züblin, in which the classic track grid is aligned in a concrete trough and then by placing filled concrete in the remaining between Betontrog and sleepers remaining spaces is permanently stabilized.
  • top down method for producing a solid roadway have in common that the amount of work, the amount of material to be used and the time that must be invested in the production of such a roadway, all are very large, which Making a fixed track for rail vehicles makes very expensive.
  • bottom-up method solid lanes can only be produced with unsatisfactory inaccuracies, which require systematic compensation by means of intermediate layers.
  • a generic method is from the EP-A-0 735 189 already known.
  • the object of the invention is therefore to provide a method for producing a track track for rail vehicles, with a solid roadway easier, faster, cheaper and with clearly defined interfaces of the trades can be made with each other than according to the known construction methods.
  • the concrete support plate can preferably be produced continuously with a Greetonfertiger.
  • the recesses are expediently made in hardened, fresh concrete, which is due to the not yet fully reached hardness of the concrete even with simple tools.
  • the recesses are expediently drilled as holes in the concrete.
  • transverse joints In the fresh concrete of the support plate transverse joints can be provided for a controlled crack formation.
  • the distance between the transverse joints depends on the specific requirements of the respective project.
  • the undercuts can be made particularly simple by being drilled in the form of threads by means of a tapping tool.
  • Each rail mounting plate is preferably provided with at least two fasteners. Before inserting the fasteners into the recesses, these are useful od.dgl of any contamination. cleaned, so as to ensure that the fasteners forcibly bounded in the recesses, preferably with an approximately equal play in all directions between them and the surrounding walls of the recesses.
  • fasteners may preferably serve bolt, which are inserted through the rail mounting plates and are screwed onto the dowels. In this case, the procedure is preferably such that the bolts are biased in their dowels before the recesses are filled with the protruding into this fastening elements with the grout.
  • the fasteners may at their projecting into the recesses area on its circumference with undercuts, in particular grooves, grooves and the like. be provided so that they after filling the recesses and hardening of the potting compound are locked in a form-fitting manner.
  • the rail mounting plates or the like Before filling the gaps and the recesses, the rail mounting plates or the like in a particularly preferred embodiment of the method according to the invention with formwork cuffs. surrounded so that it is ensured that the potting compound is actually filled only where it is actually needed, namely between the concrete slab and the rail mounting plates without being able to flow laterally.
  • the right and left rails of the track can be interconnected by means of tie rods, whereby it is then possible that at least a part of the track-guiding elements does not act on the rails themselves, but on the tie rods.
  • the rails or the track grid are aligned in at least two stages, with a first coarse adjustment stage and a subsequent Fein Rheinscut.
  • the rail fastening plates and / or the formwork sleeves can be provided with filling openings, in which case the grout can be filled through the filling openings.
  • the rail fastening plates and / or the formwork collars are preferably provided with vent holes, wherein the introduction of grout is then terminated when grout exits from the respective highest located vent hole of a formwork collar or mounting plate.
  • the formwork cuffs can be conveniently removed as already mentioned.
  • a grout quick-hardening grout is preferably used, so that it is possible to remove after a short curing time, the track alignment elements in the track section just made again and continue with the track installation in the next track section.
  • the concrete support plate designated in its entirety by 10
  • a concrete paver (not shown), which extends in the direction of the later roadway.
  • partially tachymeter controlled pavers are widely used (e.g., road construction, trough during the construction of the slab track type Rheda) and therefore will not be explained here.
  • the concrete support plate 10 is designed for a single-track route; Of course, it is also possible to make the concrete slab so wide that two or more tracks can be placed next to each other.
  • recesses 13 are drilled from the top of the support plate in the area of the later track attachment points. However, drilling can also be carried out (with increased effort) even at a later time after further hardening. It can be seen that the recesses are each between two transverse joints, thus not be placed in areas where cracks are expected later.
  • a drilling tool for the recesses is a tapping tool with a relatively coarse thread, so that the recesses do not have a cylindrical shape, but get undercuts 14 in the form of the threads produced.
  • the rail fastening plates 15 are placed on the concrete support plate 10 so that the rail fastening elements 16 protrude into the recesses 13 produced in the concrete support plate with play.
  • the diameter or the cross section of the recesses 13 to the desired backlash is greater than the cross section of the fasteners or their dowels enclosing the recesses.
  • the backlash is on the one hand chosen so large that even with consideration of manufacturing tolerances in the mounting plates and in the production of the recesses at the appropriate places the fasteners of each mounting plate easily enclosed in the recesses provided for this purpose and the plates then also still far enough can be moved laterally to allow the subsequent alignment of the track, on the other hand, the cross-section of the recesses and thus the backlash should not be unnecessarily large in order not to unnecessarily increase the amount of grout required later for attachment of the track.
  • the rails 20 are attached to them in a conventional manner with rail mounting brackets 21.
  • the rail mounting plates 15 with the attached rails still substantially flat on the concrete support plate 10.
  • the track or the rail tracks forming this can be aligned in the correct height and lateral position, and also the track spacing between the two rails is adjusted.
  • the correct height of the rails above the concrete slab is achieved by means of track straightening elements, which consist in the simplest case of wedges and attack each between two mounting plates 15 directly to the rails and are supported directly on the concrete slab.
  • the rail fastening plates 15, which are already connected to the rails at this time are at a distance above the concrete support plate and form a gap 22 between them.
  • formwork cuffs 22 are placed around the rail fastening plates, which in the preferred embodiment are formed from an inside with an anti-adhesion layer provided rubber strips which is placed under the rails at a small distance around the rail mounting plates. Subsequently, the gaps 22 between the mounting plates 15 and the concrete support plate 10 are filled with a fast-curing, low-shrinkage and well-flowing grout, which also flows into the fastening elements receiving recesses and this also fills. After curing of the grout 24, the dowels 18 are positively locked in the recesses with the potting compound and a corresponding positive bond between potting compound 24 and the walls of the recesses, because the potting compound has provided therein and provided in the dowels undercuts.
  • the rail mounting plates are on the curing of the grout to full on this.
  • the formwork sleeve 23 can be removed again after the curing of the grout, which is easily possible because of the non-stick coating. Subsequently, the bolts 17 can be tightened in their dowels 18 again to pull the rail mounting plates with force against the concrete support plate or now there, cured potting compound.
  • the bolts can be loosened in a conventional manner as soon as the grout has set and has reached a certain minimum strength.
  • the rails can then move in their rail supports to compensate for changes in length, so that during the curing of the grout no constraining forces acting on the fasteners and the casting.
