  • the invention relates to a noise barrier wall segment, for example, for roads, highways or railways u.
  • the noise barrier segment consists of one or more transparent plates, preferably made of plastic material, and the transparent plate fixing means.
  • noise protection walls, walls or noise barriers have been used for years. Because of the large footprint of ramparts, these are preferably piled up in open terrain, in the inner city area, in bridge structures and often also in rail lines noise barriers or facades are used.
  • a generic noise protection wall segment is z. B. from DE 42 30 786 A1.
  • the segment presented there consists of two edge-side vertical posts and a substantially rectangular frame, which is attached to the edge of the vertical posts, and a substantially rectangular sound absorption plate.
  • the frame has two vertical frame spars and one the two upper end portions of the two vertical frame spars connecting and adjoining these front stiffening rail, which also connects the two upper end portions of the two vertical frame spars to this fitting and the dismounted is struck.
  • the substantially rectangular sound absorption plate is dimensioned inserted into the frame and releasably supported in this.
  • the inserted into the frame sound absorption plate made of plastic can be up to 50% higher than the frame or as the vertical frame spars, so that at a given segment height of the frame must have a height that is about 2 / 3 is the height of the sound absorption plate.
  • the plates have a stiffening perpendicular to the soundproof wall, which are made of translucent material.
  • the horizontal curvature of the plates requires extensive support measures to build a vertical wall. This reduces the visual impression of a transparent wall and also leads to increased production costs.
  • DE 2743980 A describes a protective wall, in particular noise protection wall, which is particularly concerned with the task of proposing a noise barrier, which acts sound reflecting and sound absorbing.
  • a noise barrier which acts sound reflecting and sound absorbing.
  • sound-absorbing materials are introduced into the intermediate space between a load-bearing wall and individual elements.
  • the wave-like profiled wall is to reflect the sound waves back to the producer.
  • a sound-absorbing property is to be achieved by the backfilling with mineral wool.

Likewise, billboards are no problem for soundproofing walls, which is counteracted by a corresponding surface geometry in EP-A-0392923.
  • the narrow fence elements do not have to endure such loads, in particular wind loads, as they have to withstand one of the noise protection wall segments according to the invention.
  • connecting elements to the next segment are provided between each individual narrow segment. This complex construction is significantly simplified with the segments according to the invention, because they are self-supporting.
  • optically disturbing posts or frame structures are to be reduced to a minimum or even completely avoided in the new noise protection wall segment.
  • the new noise barrier segment should be industrially prefabricated, and the prefabricated segments should be easy to transport, build up and dismantle and as easy as possible interchangeable.
  • noise barrier segments should be able to be protected against splintering at break by simple means, and they should also be able to be formed to protect against collisions with flying birds.
  • the new noise protection wall should be transparent, optically inconspicuous and little noticeable.
  • the new noise barrier should also be easy to manufacture, easy to repair and inexpensive to maintain.

  • This radius of curvature is substantially freely selectable over large areas, but in practice, depending on the manufacturing method and depending on the thickness of the plates used, especially for the case of plastic plates, in particular made of acrylic glass, a radius has proved to be particularly useful, which Two hundred times the thickness does not fall below.
