Definitions

  • cassette-like wall parts made of aluminum are joined together in a caste shape to form a wall. These are mounted on spaced posts, the wall elements being inserted in the grooves of H-shaped steel profiles.
  • Such made of aluminum wall elements are usually very expensive to achieve a sufficient soundproofing effect.
  • precautions must be taken to protect the walls from the erosive effects of the environment.
  • the wall elements of a noise barrier made of a combination of compacted mineral aggregates or aggregates of glass and organic adhesive high sound insulation is achieved due to the high porosity of the wall elements and the high density of the building material. Since sound insulation values generally depend on the density of an insulating material, the high specific weight of mineral aggregates or of glass has a fundamentally high effect. Another- On the other hand, the aggregates are also significantly cheaper than metals or processed wood. This is the case in particular when using quartzite, granite, basalt and quartz as aggregates.
  • the grain size of the aggregates has a significant influence on the insulating effect, on the one hand the density of the building material, as mentioned above, should be high and on the other hand, the porosity has a dampening effect on the sound. Preference is given to aggregates whose average size of the grain is between 1 and 7 mm. With regard to the influence of the porosity, particularly favorable values result with a void fraction of up to 45%.
  • Proven average grain sizes d k of the aggregates are in a range between up to 3 mm, 2 to 3 mm, 2 to 4 mm, 2 to 5 mm or 3 to 7 mm.

  • a major advantage of using two-component epoxy resin adhesive is seen in its environmental impact.
  • the building material of the wall elements for example, has no toxic effect on molds and is considered microbially difficult to degrade. Nevertheless, substances elutable from the wall element can be well degraded, as material trials have shown. As washing tests prove, there is no chemical interaction between surface water and the building material, so that rainwater that seeps through the wall elements can be discharged untreated into the sewer or can safely drain into the groundwater. Finally, you can

  • An adhesion of the wall elements together avoids gaps through which the sound insulation could be disturbed.
  • a particularly effective improvement of the sound damping results from a construction of the noise protection wall after which the noise protection wall is designed to form gaps between two walls, wherein at least one wall is designed with the wall elements.

Abstract

La présente invention concerne une paroi d'isolation acoustique (1) ayant une structure mono- ou bicoque. Entre deux montants (2) espacés entre eux, formés d'un support en acier en forme de U, un élément de paroi (3) constitue respectivement la paroi avant et la paroi arrière de la paroi d'isolation acoustique (1). Les montants (2) sont ancrés dans le sol respectivement par l'intermédiaire d'un élément de fondation qui ne fait pas l'objet d'une plus ample description. Les éléments de paroi (3) sont mis en place respectivement sur le côté intérieur de l'arête (5) du montant (2). Les éléments de paroi (3) sont maintenus dans la gorge (6) formée dans le montant (2), dirigée vers les éléments de paroi (3), et maintiennent ainsi la pression de la matière de remplissage. Des éléments de paroi (3) respectivement de 6 cm d'épaisseur sont superposés dans la gorge (6) et collés ensemble au niveau de leurs faces. Les éléments de paroi de la paroi d'isolation acoustique, sont faits d'un ensemble de granulats minéraux compactés ou d'autres granulats de verre et d'adhésif organique. La porosité élevée des éléments de paroi, et la masse volumique élevée du matériau de construction permettent d'obtenir des valeurs d'isolation acoustique élevées.
