Definitions

  • the invention relates to an absorption to reduce the Sound radiation for a track body with two at a parallel distance from each other arranged rails, which are optionally aligned transversely to the rails Sleepers on a surface, a substructure, a bedding or the like are arranged.
  • the aforementioned noise emissions and vibrations can be in known way by elastic intermediate plates in the rail bases or be reduced by elastic storage of the entire track body.
  • a low-noise track body in which the noise reduction results from the fact that in the space between the Bedding and the rails a sound absorbing material is provided.
  • the material is essentially provided to such a height that the Wheel flanges can freely intervene in the rails.
  • the Material between the parallel rails is filled by loose filling or used in the form of modular panels.
  • a low-noise track body manufactured in this known manner does not brought significant influence on an improvement in sound radiation. According to experts, it can be assumed that because of the lack of Compression of the sound absorbing material in the track area and also because only a slight shrinkage of the material does not affect the parallel rails are clamped.
  • EP 0 404 756 A2 discloses a ballastless superstructure with rails for rail transport.
  • the rails are detachably connected to supports and have adjacent sound insulation devices on both sides of the rail web.
  • the soundproofing devices are coated on the rail held adhesive.
  • the rail web and the rail foot are completely of that Soundproofing device covered.
  • a molded part is used as a soundproofing element.
  • This middle part In addition to fulfilling sound insulation tasks, it also serves as Abutment for the pressure bodies under pressure.
  • the contact pressure of the Pressure body on the rail webs is due to an excess length of the middle part generated.
  • the elastic pressure hulls have the task of a constant press fit Apply pressure to the rails or to the rail webs and the To reduce vibrations or the vertical movements of the rail arise as a result of the rail sinking against the carriageway slab. To do this to enable and prevent vertical movement of the individual parts, are the contact surface of the molded parts and the pressure body by appropriate Rounding or rounding shaped.
  • any material can be used for the elastic pressure bodies, which remains permanently elastic even under pressure and harmless Can record rail movements.
  • Such materials are for example plastic-bound rubber granulate, closed-cell plastics, Full plastics and other materials.
  • plastic-bound rubber granulate for example plastic-bound rubber granulate, closed-cell plastics, Full plastics and other materials.
  • any available, soundproofing and largely pressure-resistant material is used, such as aerated concrete, Expanded concrete, hydraulically bound wood fibers, plastic bound Rubber granulate or a mixture of rubber granulate and grit.
  • the bottom the middle fittings are to ensure a consistently flat support and to reduce structure-borne noise with geotextile or plastic mats concealed.
  • the length corresponds to the elastic pressure hull each the base distance minus the required recess width.
  • the width of the elastic pressure body is preferably adapted to the width of the recess, if by the Rail depressions did not force smaller or larger changes in shape Widths required.
  • the recesses are partially in the middle fittings either as cantilevers or as indentations take.
  • the length of the middle fittings corresponds to that Base distance or a multiple of a base distance.
  • profiling of the surface is also possible.
  • Rail webs are also arranged elastic pressure bodies that are in length and width in an advantageous embodiment identical to the pressure elements within of the rails are. Due to the rail inclination or profiling, the shape is in Connection to the rail web changed slightly.
  • elastic Pressure bodies are again connected to molded bodies which, with regard to the material, the length, the joints and also a small animal passage the above correspond to the described middle fittings.
  • the width of this outer Insulation strips depend on the width of the printing elements and the Threshold length.
  • the track body shown in Figure 1 consists of a concrete support plate 1 as Substructure for the track body with the raised contact surfaces 2 for the two rails 3 arranged parallel to one another.
  • the rails 3 are in themselves known way firmly attached to the concrete support plate.
  • the absorption covering to reduce the sound radiation for the track body consists of the two rails 3 consists of a middle between the rails 3 arranged molded body 4, the two facing the rails 3 End faces against pressure body 5 is under pressure.
  • the two are there End faces of the central molded body 4 arc-shaped or circular arc-shaped or designed in another way with positive locking.
  • the adjacent end faces of the Pressure pieces 5 have corresponding surfaces.
  • the pressure pieces are lying with their end faces facing the rail webs 8 of the rails 3 below Pressure firmly on the rail webs 8, the end faces of the pressure piece 5th are simultaneously designed so that they are in the space between the rail head 10 and the rail foot 9 lie closely.
  • the middle molded body 4 is in from above the slightly inclined pressure body 5 pressed. Because the overall measure of both lateral pressure body 5 and the central molded body 4 is larger than that Dimension between the mutually facing rail webs 8, are in the final state According to Figure 1, the pressure body 5 flush under pressure on the rails 3.
  • the amount of pressure is dependent on the elasticity of the pressure body 5 special shape of the end faces of the molded body 4 and the pressure body 5 on the one hand, assembly is made considerably easier and, on the other hand, it is ensured that the composite of pressure bodies and moldings is not automatically from its End position is coming. With this design, the end position is also ensured if high-speed trains with a very high suction effect over the Drive the noise protection system.
  • the Shaped bodies 4 and 7 are designed as hydraulically bound insulating bodies.
  • Cavity 12 is provided for the passage of small animals.
  • FIG. 3 is a top view of the combined sound insulation system according to FIG. 1 drawn.
  • those running across the rails 3 are Joints 13 of the molded bodies 4 and 7 lying against each other in this area clearly to see.
  • Figure 4 is a sectional view of a track body corresponding to the Representation drawn in Figure 1.
  • the central molded body in this case consists of two Share 15 is formed. These two parts 15 of the central molded body are mechanically pressed against the pressure pieces 5 or the rails 3. Into that The resulting middle joint 16 is then used to fill the Tension of the composite of molded bodies and pressure bodies against the rails 3 maintain.
  • the dash-dotted line in the middle of the Shaped body is indicated that instead of a vertical joint with filler 17th a step-like separation of the two molded parts 15 can also be set up can, in turn fillers are to be used.
  • the moldings can advantageously also prefabricated in a suitable manufacturing plant and be assembled. This would insert the filler on the Construction site on the track body can be omitted.
