Schallschutzvorrichtung Soundproofing device
Beschreibungdescription
Die Erfindung betrifft eine Schallschutzvorrichtung zur Reduzierung der Luftschallausbreitung, umfassend eine Gleisanlage und eine in Gleislängsrichtung verlaufende und elastisch verformbare Niedrigschallschutzwand aus Gummi oder Kunststoff, wobei die in einem Abstand zum Gleis angeordnete Niedrigschallschutzwand auf ihrer zum Gleis hin zugewandten Seite (Innenseite) eine Profilierung aufweist, die sich im wesentlichen über die gesamte Wandhöhe erstreckt, während ihre dem Gleis abgewandte Seite (Außenseite) zumeist ebenflächig gestaltet ist (DE-A-44 34 269).The invention relates to a soundproofing device for reducing airborne sound propagation, comprising a track system and an elastically deformable low-soundproofing wall made of rubber or plastic that runs in the longitudinal direction of the track, wherein the low-soundproofing wall arranged at a distance from the track has a profiling on its side facing the track (inside). which extends essentially over the entire wall height, while its side facing away from the track (outside) is mostly flat (DE-A-44 34 269).
Höhere Anforderungen an den Schallschutz von Bahnanlagen bedingen, daß die Schallschutzwände näher an die Gleise und damit an das Lichtraumprofil heranrücken bzw. in das Lichtraumprofil hineinragen. Eine Schallschutzwand hat dabei zwei unterschiedliche Anforderungen zu erfüllen. Einerseits soll die Schallschutzwand als Schallschirm die Sichtverbindung vom Emissionsort zum Immissionsort unterbrechen und eine möglichst hohe Beugungskante ermöglichen. Andererseits soll der auf der Seite des Emissionsortes auftreffende Luftschall möglichst effektiv absorbiert werden bzw. so reflektiert werden, daß der Luftschall anderweitig absorbiert wird.Higher requirements for the soundproofing of railway systems mean that the soundproofing walls move closer to the tracks and thus to the clearance profile or protrude into the clearance profile. A soundproof wall has to meet two different requirements. On the one hand, the soundproofing wall, as a sound shield, should interrupt the line of sight from the emission location to the immission location and enable the highest possible diffraction edge. On the other hand, the airborne sound impinging on the side of the emission location should be absorbed as effectively as possible or reflected in such a way that the airborne sound is otherwise absorbed.
Im Hintergrund der oben genannten Anforderungen soll nun eine Niedrigschallschutzwand bereit gestellt werden, die so gestaltet ist, daß bei eventuellen Kollisionen kein Wagenmaterial beschädigt wird. Ferner soll auch bei kleineren Beschädigungen der Niedrigschallschutzwand ihre Funktion nicht wesentlich reduziert werden.In the background of the above-mentioned requirements, a low-noise barrier should now be provided, which is designed in such a way that no car material is damaged in the event of collisions. Furthermore, its function should not be significantly reduced even in the event of minor damage to the low-noise barrier.
Die erfindungsgemäße Niedrigschallschutzwand zeichnet sich nun dadurch aus, daßThe low noise barrier according to the invention is now characterized in that
- ihre Innenseite in einem Winkel α und ihre Außenseite in einem Winkel ß, und zwar jeweils bezogen auf die Gleissenkrechte, zum Gleis hin geneigt sind, wobei der Winkel ß größer als der Winkel α ist; - die Profilierung der Innenseite ein System von Lippen ist, wobei die Lippen in einem Winkel γ, und zwar bezogen auf die Gleishorizontale, zum Gleisboden zeigen;- Their inside at an angle α and their outside at an angle ß, in each case with respect to the track perpendicular, are inclined towards the track, the angle ß being greater than the angle α; - The profiling of the inside is a system of lips, the lips pointing to the track floor at an angle γ, in relation to the track horizontal;
- die Niedrigschallschutzwand oben, wo die Innenseite und Außenseite aufeinander zulaufen, durch eine zum Gleis hin geneigte Lippe abgeschlossen ist, die in einem Winkel δ, und zwar bezogen auf die Gleissenkrechte, nach oben zeigt, und daß- The low-noise barrier above, where the inside and outside converge, is closed by a lip inclined towards the track, which points upwards at an angle δ, relative to the track perpendicular, and that
- die Niedrigschallschutzwand wenigstens einen in Gleislängsrichtung verlaufenden Hohlraum aufweist.- The low noise barrier has at least one cavity running in the longitudinal direction of the track.
Hinsichtlich der Winkel α, ß, γ und δ gelten dabei zweckmäßigerweise folgende Winkelbereiche:With regard to the angles α, β, γ and δ, the following angle ranges expediently apply:
α = 5 bis 10° ß = 10 bis 20° γ = 40 bis 60° δ = 30 bis 45°α = 5 to 10 ° ß = 10 to 20 ° γ = 40 to 60 ° δ = 30 to 45 °

Ferner sollte der Werkstoff der Niedrigschallschutzwand einen hohen Verlustfaktor (d = 0,08 bis 0,4), und zwar im Vergleich zu Beton und Stahl, haben.Furthermore, the material of the low-noise barrier should have a high loss factor (d = 0.08 to 0.4) compared to concrete and steel.

Die Innenseite 6 der Niedrigschallschutzwand 5 weist einen Neigungswinkel α von insbesondere 5 bis 10° auf, und zwar bezogen auf die Gleissenkrechte X. Außerdem ist sie oben durch eine zum Gleis 1 hin geneigte Lippe 9 abgeschlossen, die nach oben zeigt, wobei der Neigungswinkel δ insbesondere 30 bis 45° beträgt, und zwar ebenfalls bezogen auf die Gleissenkrechte X. Durch die Winkelkonstellationen gemäß und δ wird der von Rad und Schiene abgestrahlte Luftschall in optimaler Weise zum Gleisboden 4 reflektiert.The inside 6 of the low-noise barrier 5 has an angle of inclination α of in particular 5 to 10 °, in relation to the track perpendicular X. In addition, it is closed at the top by a lip 9 inclined towards the track 1, which points upwards, the angle of inclination δ is in particular 30 to 45 °, also based on the track perpendicular X. The angle constellations according to and δ reflect the airborne sound emitted by the wheel and rail in an optimal manner to the track floor 4.
Die Innenseite 6 der Niedrigschallschutzwand 5 ist ferner mit mehreren Lippen 8 versehen, die zum Gleisboden 4 zeigen, wobei der Neigungswinkel γ insbesondere 40 bis 60° beträgt, und zwar bezogen auf die Gleishorizontale Y. Mit diesem Lippensystem wird vor allem der hoherfrequente Luftschall absorbiert, indem der Luftschall im Bereich der Lippen 8 mehrfach reflektiert wird. Diese Lippen haben vorteilhafterweise eine Mindestlänge in Erstreckungshchtung von 5 mm, insbesondere eine Länge von 10 bis 20 mm.The inside 6 of the low-noise protection wall 5 is also provided with a plurality of lips 8, which face the track floor 4, the angle of inclination γ being in particular 40 to 60 °, specifically with respect to the track horizontal Y. This lip system primarily absorbs the high-frequency airborne sound, by repeatedly reflecting the airborne sound in the area of the lips 8. These lips advantageously have a minimum length in the direction of extension of 5 mm, in particular a length of 10 to 20 mm.
Die nach oben zeigende und die Niedrigschallschutzwand 5 abschließende Lippe 9 ist länger als die zum Gleisboden 4 zeigenden Lippen 8. Die Höhe H der Niedrigschallschutzwand 5 beträgt zweckmäßigerweise 300 bis 700 mm.The lip 9 pointing upwards and closing the low-noise protection wall 5 is longer than the lips 8 pointing towards the track floor 4. The height H of the low-noise barrier 5 is expediently 300 to 700 mm.
Die in der Niedrigschallschutzwand 5 enthaltenen und in Gleislängsrichtung verlaufenden Hohlräume 10 wirken als Hohlraumresonatoren, um vor allem niederfrequenten Luftschall zu absorbieren. Zur Erzielung einer möglichst großen Absorptionsbreite weisen die Hohlräume vorteilhafterweise ein unterschiedlich großes Volumen auf.The cavities 10 contained in the low-noise protection wall 5 and extending in the longitudinal direction of the track act as cavity resonators, in particular to absorb low-frequency airborne noise. In order to achieve the largest possible absorption width, the cavities advantageously have different volumes.
Die Befestigung 11 der Niedrigschallschutzwand 5 erfolgt etwa in Höhe der Schienenbefestigung 3, vorzugsweise im Bereich des Schwellenrandes.The fastening 11 of the low-noise protection wall 5 takes place approximately at the height of the rail fastening 3, preferably in the area of the threshold edge.
Nach einer Ausgestaltungsvariante sind die Lippen 8 auf der Innenseite 6 der Niedrigschallschutzwand 5 mit einer Dämmatte 12 abgedeckt, wobei die Dämmatte vorzugsweise aus einem geschäumten oder faserigen Werkstoff besteht, was zu einer weiteren Reduzierung der Luftschallsausbreitung führt.
