Definitions

  • the invention relates to a sleeper frame for a track system for rail-bound Vehicles, in particular for a ballast track, with the features the preamble of claim 1.
  • Such a component is known from CH 545 376 compared to the conventional one Ballast superstructure with cross sleepers have threshold frames Advantage of a more uniform bedding in the ballast, a lower ballast pressure under the wheel arches and an increased lateral displacement resistance.
  • a railway superstructure is known from AT-PS 377 806, in which individual frame elements are strung together, each rail on a frame element is mounted by means of several outsourcers.
  • the frame elements can use dowels on the end faces to absorb larger transverse forces be connected.
  • the reinforcement of this manufactured in prestressed concrete Elements are made by tendons, each between two each other opposite end faces of the element run straight.
  • the present invention is therefore based on the object of a threshold frame for a track system for rail vehicles, especially for to create a ballast superstructure in which none, even with high lateral forces elaborate connection of the threshold frames in the transverse joints or highly elastic Rail supports in the area of the rail fastenings are necessary and a decrease in the frequency of those generated in the rail vehicle Allows vibrations. Furthermore, a simple and inexpensive Methods for producing such threshold frames are created.
  • the particular advantages of the threshold frame according to the invention exist in that through the rail fastenings placed on the outside of the frame edge on the one hand the vertical gap in the transverse joint is reduced as far as possible, a connection between the threshold frames can be dispensed with can; In addition, the distance between the rail fastenings is in this way significantly increased with the result that the frequency of vibrations reduced accordingly.
  • the outer rail supports great rigidity in the area of rail fastenings and the medium one Rail support on a low rigidity, the surface of the support middle rail support before the rail assembly is significantly higher than that the outer rail support so that the rail fastenings are tightened the middle rail support up to the height of the outer rail supports is compressed and receives a compressive prestress.
  • the Cross sleepers and / or the side members an elastic material, preferably an elastic mat is provided.
  • the pre-compression in the middle rail support can depend on its rigidity and pre-press height are adjusted so that the vertical rail countersink under the wheel load both in the center of the frame and in the rail fastenings becomes the same size and in this way a continuous one Rail support corresponds.
  • the vibration damping of the Systems further improved.
  • each Rail axis provided a side member.
  • This can create a continuous or quasi-continuous storage of the rail achieved in a simple manner are, for example, without providing the cross sleepers very closely to one another to have to.
  • the number of cross sleepers can in particular be reduced to two become.
  • under a quasi-continuous Storage of the rail is a storage in close to each other Points or areas is to be understood without being in the areas in which no storage is provided, one of the desired bending line Rail generates significant deviation under load.
  • the position of the outer rail supports and / or the rail fastenings is chosen so that the central plane of the rail fastenings is transverse to the course the rails have a distance of less than or equal to 15 cm, preferably less than or equal to 10 cm from the outer boundary of the threshold frame in the longitudinal direction With appropriate dimensions of the cross sleepers in the longitudinal direction a central arrangement of these elements with respect to this dimension.
  • the cross sleepers are. and the one longitudinal beam in one piece, preferably as a prestressed concrete element educated. This results in a simple, rational possibility the production.
  • the threshold frame can be designed as a prestressed concrete part or it can be outer manufactured as normal concrete parts or prestressed concrete parts Areas of the cross passages (and possibly the side members) with a connecting rod be connected in the form of a metal profile.
  • the reinforcement of the threshold frame Clamping elements used on the end faces of a cross sleeper are anchored.
  • the tensioning elements are arched from this cross sleeper led a side member to a second cross sleeper and on the end faces anchored.
  • At least two U-shaped rotated against each other by 180 ° Clamping elements may be provided, the ends of which are respectively opposite one another End faces of two cross sleepers are anchored.
  • the arches of the tensioning elements can run through the same side member or with two or more Side members by one side member each, which is closer to that End faces of the cross sleepers, in which the ends of each other Clamping element are anchored.
  • the tensioning elements can also be essentially Z-shaped be, the ends of a tensioning element at respectively opposite ends different cross ties are anchored.
  • a threshold frame which has at least two longitudinal beams, at least four Z-shaped ones Clamping elements are provided, with two Z-shaped ones Cross the clamping elements in the same side member.
  • Such a threshold frame it can first be used Expansion joints are made in the side members. The tensioning elements are then prestressed by expanding the joints. The expansion joints are finally closed with a suitable hardenable building material so that there is a positive and non-positive connection in the expansion joints. Of course, a different type of suitable fixation of the prestressed can also be used Position of the threshold frame can be made.
  • FIG. 1 The section of a track system shown schematically in Figure 1 in plan view shows an embodiment of a threshold frame with two cross sleepers 1, which with two longitudinal beams 2 to a preferably one-piece Component are connected.
  • the formation of rail fastenings 3 with associated outer rail supports 4 correspond to the known state of the Technology.
  • the limitation of the frame size in the longitudinal direction to only two near the Transverse joint arranged rail fastenings 3 with the two outer rail supports 4 has the advantage that the frame without the constraint of under the wheel load occurring rail sink can follow and only slight at the transverse joints Lowering differences occur. This also keeps them in the transverse joint shear forces to be transmitted so low that they without the rails 6 essential additional stress are transferred. An additional connection in the transverse joint is no longer necessary.
  • the middle rail support 5 between the outer rail supports 4 has the task, on the one hand, of the more self-supporting rail 6 against the To support wheel loads ver and on the other hand vibrations in the rail 6 dampen.
  • the mode of operation of the middle rail support 5 described here is before especially with large dimensional tolerances in the gap between the rail 6, and the Side member 2 useful.
  • the distance between the individual threshold frames i.e. between the dense juxtaposed outer cross sleepers 1 and 1 'should be as low as possible his.
  • a changing gap width is required when laying in curves; on the other hand, the laying may not be carried out by individual ones in the gap Gravel stones are hindered. In this respect, a distance of approx. 5 cm appears appropriate.
  • the becomes monolithic Threshold frames described as prestressed concrete components are shaped that he is in favor of manufacturing as a reinforced concrete component according to that for two-block sleepers known principles. So that the advantages of the invention Transfer threshold framework to another area of application.
