Definitions

  • the invention relates to a noise barrier with a load-bearing wall part of supporting concrete and a ceramic facing shell or the like as a sound absorption layer.
  • Noise barriers are known in which the sound absorption layer consists of cement-bound wood chips.
  • the object of the invention is to avoid these known disadvantages and to disclose a noise barrier in which the long-term strength of the sound absorption layer remains practically indefinitely constant.
  • the sound channels of the sound absorption layer should be able to be adapted very accurately to the sound to be absorbed.
  • the noise barrier consists of a load-bearing wall slab of supporting concrete and a ceramic facing shell or the like as a sound absorption layer.
  • the surface of the sound absorption layer may be provided with a profiling.
  • the profiling may e.g. consist of ribs and intermediate valley areas.
  • the essential components of the sound absorption layer are fired expanded clay bodies and a binder.
  • the majority of the expanded clay body has a uniform grain size.
  • the expanded clay bodies are spherical.
  • the binder may be cementitious or made of a synthetic resin or the like.
  • the binder is disposed as a layer on the surface of the expanded clay bodies, so that sound absorption channels are present between the expanded clay bodies.
  • the sound absorption layer can also be designed as a multilayer.
  • each sound absorption layer has a relatively uniform, but different sized grain size.
  • the outer sound absorbing layer is made of a mixture having a smaller grain size than the inner sound absorbing layer. Since more binders must be used when using smaller expanded clay bodies, the outer sound absorption layer also has a higher strength.
  • the binder and in particular the amount of the binder, is adapted to the expanded clay body or to the grain of the expanded clay body.
  • the binder should be arranged only as a layer on the surface of the expanded clay body, the total amount of the binder depends on the grain size of the expanded clay body. The smaller the grain size, the larger the total surface area of all spherical expanded clay bodies per unit volume. Since the binder is the most expensive component of the sound absorption layer, the manufacturing costs are higher when using a small grain size of the expanded clay body than with a larger grain size. It is therefore useful for cost reasons, adjust the amount of binder to the grain size of the expanded clay body.
  • Compliance with the selected grain size of expanded clay body can be done via a screening of the expanded clay after sintering of the granules.
  • the amount of the binder and the size of the sound absorption channels can be maintained relatively accurately when the expanded clay bodies are spherical, because no body parts of the expanded clay bodies can push into the sound absorption channels when compacting the sound absorption layer.
  • the noise protection wall - as shown in FIGS. 1, 3 and 4 - consists of a load-bearing wall plate 1 of supporting concrete and a ceramic facing shell as sound absorption layer 2.
  • the surface 3 of the sound absorption layer 2 is provided with a profiling 4.
  • the profiling 4 consists of ribs 5 and intermediate valley regions 6.
  • the essential components of the sound absorption layer 2 are fired expanded clay bodies 7 and a binder 8.
  • the majority of the expanded clay body 7 has a uniform grain, as the enlarged sectional view of FIG. 2 shows.
  • the expanded clay bodies 7 are spherical.
  • the binder 8 is arranged as a layer 9 on the surface 10 of the expanded clay body 7, so that between the expanded clay bodies 7 sound absorption channels 11 are present.
  • the sound absorption layer 2 can also have a multilayer structure, as shown in FIGS. 3 and 4:
  • each sound absorbing layer 12 and 13 has a relatively uniform but different sized grain size.
  • the outer sound absorbing layer 12 is made of a mixture having a smaller grain than the inner sound absorbing layer 13.
  • the binder 8 should be arranged only as a layer 9 on the surface 10 of the expanded clay body 7, the total amount of the binder 8 depends on the grain size of the expanded clay body 7. The smaller the grain size, the larger the total surface area of all spherical expanded clay bodies 7 per unit volume.
