Definitions

  • the invention relates to a rail fastening system for fastening a rail on a rail base, preferably on a solid roadway.
  • the rail fastening system has a rail base plate, which is set up to hold the rail, and a base plate, which is set up to fix the rail base plate on the rail base.
  • railway tracks and switches are laid on sleepers or a so-called "fixed roadway".
  • the solid carriageway is mostly a flat, continuous concrete slab that serves as a sub-surface for the tracks instead of a ballast superstructure.
  • Rail base plates and intermediate plates which are at least partially flexible, are used to fasten a rail track to a fixed carriageway. When rolled over by a wheel of the rail vehicle, the running or stock rail deflects due to the flexible mounting, which dampens noise and vibrations.
  • the attachment structure according to the DE 101 39 198 A1 Although it only requires one fastening element per side and no additional concrete shoulder, it is not readily possible to regulate the height of the rail, for example by means of intermediate plates between the threshold and the rail base plate, since otherwise the shear force load on the angle guide plate would be too great.
  • the US 2013/0168460 A1 describes a fastening structure in which replacement shoulders are used, which are integrally connected to one another in order to derive the transverse forces that occur via one fastening element per side. Under real operating conditions, however, the load is non-uniform due to manufacturing tolerances, ie the lateral forces are mainly derived via a fastening element. This system is also overdetermined. In addition, the assembly and disassembly of the system is made difficult by the high replacement shoulders.
  • An object of the invention is to provide an improved rail fastening system for fastening a rail to a rail sub-surface, preferably a solid track.
  • the rail fastening system is used for releasably fastening a rail on a rail base.
  • the rail base is preferably a solid roadway, such as a concrete base, but can also be a railroad tie or another suitable rail base.
  • the rail fastening system has a rail support plate which is designed to hold the rail, the rail being in contact with the rail support plate in the assembled state for this purpose and being fastened thereon by means of a rail holder.
  • the rail base plate is, for example, a molded part made of steel.
  • the rail fastening system also has a base plate, which is used to fasten the rail base plate is set up on the rail base, the rail base plate being fastened in the assembled state via one or more, preferably two, holding members on the base plate and the base plate being in contact with the rail base.
  • a holding member is preferably provided on each side.
  • the rail base plate and the base plate do not necessarily have to be in direct contact with one another here, since, for example, one or more spacer plates (described in detail below) and / or one or more flexible intermediate plates (also described in detail below) are provided between the two plates can.
  • the base plate ensures the connection of the rail fastening system to the rail base.
  • the base plate is formed in several parts, preferably in two parts, so that it can be adjusted to different dimensions of the rail base plate.
  • the division of the base plate is preferably provided in such a way that it can be adjusted along the transverse direction.
  • the "transverse direction” here denotes the direction that is perpendicular to the plane, which is formed by the longitudinal direction of the rail and the direction of gravity.
  • the transverse direction thus corresponds to the main direction of extension of a threshold in the assembled state. It should be noted that the terms “top”, “bottom”, “vertical”, “vertical”, “transverse”, “lengthwise” etc. are clear here, since the rail and the rail fastening system in the assembled state in a clear position come into use.
  • the base plate is formed in several parts, for example with a first base plate section and a second base plate section that is adjustable relative to it, the base plate can be adapted to different rail base plates, for example in the tongue, intermediate rail and frog area of a switch.
  • the Rail fastening system is thus universally adaptable and at the same time ensures reliable power transmission, in particular the lateral force, from the wheel of a rail vehicle into the rail ground.
  • the rail fastening system also has at least one intermediate plate made of a flexible material, which is arranged between the base plate and the rail base plate in the assembled state.
  • the intermediate plate improves the mounting of the rail base plate and is used for shock and sound decoupling between the rail and the rail base.
  • the material of the intermediate plate preferably has a static rigidity of approximately 200 kN / mm or less.
  • the intermediate plate can also be formed in several parts in order to further improve the adaptability of the rail fastening system.
  • the rail fastening system preferably also has at least one spacer plate which is arranged in the assembled state between the base plate and the rail base plate.
  • the spacer plate can be used to compensate for any existing height tolerances of the rail base.
  • the spacer plate is made, for example, from a metal or a plastic.
  • the spacer plate is preferably designed in several parts, for example in two parts, so that it can be adjusted to different dimensions of the rail base plate. In this way, the adaptability of the rail fastening system can be further improved.
  • the holding members preferably each have one or more tensioning clamps which are designed to press the rail base plate against the base plate with a defined force.
  • the holding members can be designed in such a way that their tensioning clamps overlap the ends of the rail base plate and press them onto the base plate. In this way, the rail base is held in the vertical direction.
  • the tension clamps are preferably designed with a high vertical fatigue strength, the exact shape, material thickness and spring constant can vary depending on the application.
  • the holding members each have an angle guide plate, which are set up to define the position and position, and to support an associated tension clamp. In this way, the desired holding forces can be reliably and permanently realized.
  • the holding members for example their angle guide plates, are preferably set up such that they are each butt-flush positioned in the transverse direction in contact with an end face of the rail base plate, the contacting end faces of the rail base plate and the holding members being set up in such a way that they are one form-fitting connection.
  • the angle guide plates are T-shaped for this purpose, so that a projection of the same engages in a corresponding recess in the end face of the rail base plate in the assembled state, as a result of which the face ends of the rail base plate and the angle guide plate in contact form a positive connection. In this way, longitudinal walking of the rail base plate is prevented in a structurally simple manner.
  • the holding members preferably each have a dowel and a screw-shaped fastening element which is anchored in the rail base by means of the dowel.
  • the holding members are particularly preferably set up such that the dowels can be screwed out of the rail base from above when the base plate is installed. All components are therefore easy to replace. This is especially true when the dowels are embedded in a concrete rail base. Maintenance of the rail fastening system, replacement of components, etc. can be carried out without destroying or damaging the rail base.
  • the base plate preferably has replacement shoulders at the two end sections in the transverse direction, which are set up to stabilize the rail base plate in the transverse direction. In this way, the lateral forces can be more reliably dissipated into the rail base.
  • the underside of the base plate has a structure of elevations and depressions, for example a chamber structure, which is set up to interlock with the rail base, whereby the base plate is further stabilized on the rail base.
  • a structure of elevations and depressions for example a chamber structure, which is set up to interlock with the rail base, whereby the base plate is further stabilized on the rail base.
  • the rail fastening system shown in the Figures 1 to 3 has a rail base plate 1 for holding a rail 2 to be mounted thereon.
  • the rail base plate 1 is, for example, a molded part made of steel.
  • the rail 2 is located in the area of a switch.
  • another rail section 2 ' shown.
  • the rail fastening system can also be used outside a switch, in the normal track area.
  • the exact shape of the rail base plate 1 can be adapted to the respective application environment.
  • the rail base plate 1 has a rail holding section 1a, which determines the position of the rail 2 on the rail base plate and contributes to the mounting of the rail 2.
  • the rail 2 is further clamped against the rail base plate 1 by one or more rail clamps 1b and / or rail clamps 1c.
  • the rail holding section 1a, the Rail clamp 1b and the rail clamp 1c form an exemplary implementation for a rail holder which is set up for fastening the rail 2 on the rail base plate 1.
  • An intermediate plate 4 which is part of the rail fastening system, made of a flexible material can be arranged between the rail base plate 1 and a base plate 3 (described in detail below).
  • the intermediate plate 4 is, for example, a highly elastic plate made of an elastomer and preferably has a static rigidity of approximately 200 kN / mm or less.
  • the intermediate plate 4 guarantees an optimal storage of the rail base plate 1 and serves the shock and sound decoupling between the rail 2 and a rail base, which in the Figures 1 to 3 is not shown.
  • the rail fastening system can have a spacer plate 5, which is located under the intermediate plate 4, in order to compensate for any existing height tolerances of the rail base.
  • the spacer plate 5 can be made of a metal or a plastic. According to the present exemplary embodiment, the spacer plate 5 is likewise formed in two parts, with a first spacer plate section 5a and a second spacer plate section 5b.
  • the rail fastening system also has a base plate 3 on which the rail base plate 1, the optional intermediate plate 4 and the optional spacer plate 5 are fastened.
  • the base plate 3 ensures the connection of the rail fastening system to the rail base.
  • the base plate 3 has replacement shoulders 3e at the two end sections in the transverse direction, which are set up to stabilize the rail base plate 1 in the transverse direction.
  • the base plate 3 is formed in several parts, in the present embodiment in two parts, with a first base plate section 3a and a second base plate section 3b. In this way, the base plate 3 can be adapted to different rail base plates 1, for example in the tongue, intermediate rail and frog area of a switch.
  • the rail base plate 1 is fixed in position on the base plate 3 by means of two holding members 6. On each side in the transverse direction, one of the holding members 6 (more precisely, whose angle guide plates 8 described below) is positioned flush against an end face of the rail base plate 1.
  • the contacting end faces of the rail base plate 1 and the holding members 6 can have corresponding shapes (projections, depressions, etc.) in order to achieve a positive connection. In this way, longitudinal walking of the rail base plate 1 is prevented.
  • the holding members 6 and / or the rail base plate 1 can have other or further means for positive and / or non-positive connection in order to ensure a secure mounting of the rail base plate on the base plate 3.
  • the holding members 6 each have a tension clamp 7 which overlap the ends of the rail base plate 1 and press it against the base plate 3 with a defined force. In this way, the rail base plate 1 is held in the vertical direction.

  • the underside 3d of the base plate is as from the Figure 3 emerges, preferably structured like a chamber, whereby it interlocks with the rail base. In this way, occurring wheel forces can be diverted particularly reliably into the rail base.
  • the rail fastening system set out above is particularly suitable for mounting on a solid carriageway made of concrete, wherein the dowels 10 are embedded in the concrete and can be unscrewed and replaced at any time after installation without removing the base plate 3 from the latter. All components are therefore easy to replace. As far as applicable, all individual features that are shown in the exemplary embodiments can be combined and / or exchanged with one another without leaving the scope of the invention.
