Definitions

  • the invention relates to a noise barrier element according to the preamble of the claim 1.
  • Noise protection wall elements for assembling noise protection walls are in various Embodiments known. You can find on railways, Roads or the like Use to locate the residents by rail or To protect road vehicles from noise or noise. You will be on Pillars or the like. Assembled and assembled to noise barriers, depending on Country and place of use can have different thicknesses and minimum standards have to fulfill.
  • the noise protection wall elements generally have a multilayer structure on. It is known to use a base plate for airborne sound insulation an absorption layer of minerals is applied for sound absorption. These two Layers can in turn be protective, e.g. von Blechen or the like be surrounded.
  • the object of the invention is to solve this problem.
  • the absorption layer has at least a multi-layer structure two absorption layers of different density, the density of the absorption layers to the side facing away from the sound, which increases the sound absorption properties of the element significantly improved.
  • the absorption layer has a three-layer structure has three absorption layers of different bulk density, the The density of the absorption layers on the side facing away from the sound increases.
  • the absorption layers preferably consist of mineral wool of different densities.
  • the sheet metal cover is further preferably formed as a perforated sheet.
  • Figure 1 shows a noise barrier wall element 1, which on its the sound or Noise source, such as a road, side has a sheet metal cover 2.
  • the direction of the main sound incidence is marked with the arrow S.
  • the sheet metal cover 2 is preferably designed as a perforated sheet (not to be seen here).
  • the individual holes of the perforation in particular have a diameter of less than 12 mm, in particular less than 10 mm, particularly preferably one Diameter of less than 8 mm, with the holes spaced at a grid are arranged.
  • the absorption layer follows the sheet metal cover 2. This shows a three-layer here Building on. It comprises three adjacent absorption layers 3, 4, 5, which each made of a fiber insulation material, in particular mineral wool different Density exist, the density of mineral wool according to a knowledge of Invention particularly preferably increases away from the sound source, i.e. the first Absorption layer 3 has a lower density than the middle absorption layer 4, which in turn has a lower density than the outer one facing away from the sound source Absorbent layer 5 has.
  • the density, in particular the bulk density, of the first absorption layer 3 is preferably 40 kg / m 3 to 60 kg / m 3 , in particular 50 kg / m 3
  • the bulk density of the middle absorption layer 4 is 60 to 80 kg / m 3 , in particular 70 kg / m 3 and the raw position of the outer absorption layer 5 facing away from the sound source at 80 or more kg / m 3 , in particular at 100 kg / m 3
  • the individual absorption layers 3, 4 and 5 are preferably more than 30 mm, in particular each 60 mm thick.
  • a pressed can be placed on the outer absorption layer 5 facing away from the sound source follow material 6 to stiffen the element (e.g. a cement-bound one Fiberboard).
  • the element e.g. a cement-bound one Fiberboard
  • the sheet metal covers 2 and 7 can each be made of sheet metal such as aluminum or steel and on the outer edges and / or surfaces of the soundproof wall element around the rest of the layers.
  • Hollow metal profiles 8 serve for stiffening and Stabilization of the soundproofing element. They can run parallel to each other so in the middle and / or on the sides of the noise barrier element.
