Definitions

  • the present invention relates to a sound insulation wall element for a track system according to the preamble of claim 1.
  • a sound insulation wall element according to the preamble of claim 1 is known from EP 0 527 115 A1 known.
  • This soundproofing wall element has a soundproofing wall element body made of metal material, which has a recess on the side facing a sound source.
  • a multi-layered soundproofing insert element is accommodated in the recess.
  • the recess and the soundproofing insert element accommodated therein are covered by a plate-like holding element made of metal material and having a large number of slot-like sound passage openings, by means of which the soundproofing insert element is held in the recess and thus on the soundproofing wall element body.
  • the DE 10 2014 217 767 A1 discloses a sound insulation wall element with a support structure made up of a plurality of square metal tubes. Sound insulation elements made of rubber material are supported on the support structure made of metal material.
  • the EN 10 2012 105 983 A1 discloses an acoustic shielding unit which has a body constructed from concrete material with a recess for receiving a stone fill acting as a sound-insulating element.
  • the WO 2010/128937 A1 discloses an acoustic shielding unit which has a replaceable cassette with sound-absorbing material accommodated therein on a body constructed with concrete material.
  • the KR 200 428 133 Y1 discloses a sound-absorbing wall with a frame constructed from an upper plate, a lower plate and two side struts, on which a sound-absorbing structure is supported.
  • the EP 1 916 338 A1 discloses a self-supporting, sound-absorbing concrete slab, which, starting from a base area, has a substantially plate-like body. Several blocks made of sound-absorbing material are supported on the plate-like body.
  • a sound insulation wall for a track system constructed with a plurality of sound insulation wall elements is known.
  • the individual sound insulation wall elements are fixed in a base edge area directly at the outer ends of the sleepers of a track system. Since the base edge area is close to the rails of the track system, the sound insulation wall elements extend diagonally outwards from the base wall area away from the rails and upwards in order to avoid interference with the control light space that must be kept clear for trains. This also requires a comparatively low height of the sound insulation wall elements positioned very close to the rails and requires a complex surface structure provided on the sound insulation side of the same in order to avoid upward sound reflections.
  • the sound insulation wall elements are designed as solid bodies made of rubber material.
  • a soundproofing wall for a track system constructed with a plurality of soundproofing wall elements is known, in which the soundproofing wall elements are supported by means of a support structure on a rail of a track system adjacent to them.
  • the support structure comprises a plurality of beam-like supports which are fixed to a rail foot of a rail immediately adjacent to this and extend outwards to the sides, to which the soundproofing wall elements are fixed.
  • the soundproofing wall elements themselves extend upwards from the fixing to the support structure and curved towards the track body in order to achieve a reflection of sound emitted from the area of the rails in a downward direction into the track body. This means that in order to avoid an interference with the standard clearance, the soundproofing wall elements have a have a comparatively low height.
  • the sound insulation wall elements themselves are constructed as hollow bodies with a wall made of plastic material.
  • the separation of the functions of sound insulation on the one hand and structural strength on the other into different components of the soundproofing wall element creates the possibility of providing each of these components with an optimized design or optimized construction material to fulfill the respective function.
  • the soundproofing insert element primarily serves to absorb the sound emitted by a train traveling on a track system, but does not itself have to contribute to providing structural strength.
  • the soundproofing wall element body gives the soundproofing wall element its structural strength, but does not have to be designed with a special, comparatively complex and difficult to manufacture shape in order to be able to achieve the required sound insulation through this alone.
