Definitions

  • the present invention relates to a noise protection wall consisting of a multiplicity of wide-flange beams arranged at a distance from one another, between which a multiplicity of noise protection elements arranged vertically one above the other are arranged.
  • Noise protection walls are structures designed to protect against acoustic pollution, in particular against anthropogenic noise and other acoustically effective pollution in urban and rural public and non-public spaces.
  • these walls consist of so-called wide-flange beams that are embedded in the ground or subsoil at regular intervals and are firmly anchored.
  • wide flange beams also called double-T or Peiner beams, are understood to be steel beams that are used in steel construction, e.g. B. hall construction, bridge construction, industrial and commercial construction.
  • HEA, HEB and HEM are the typical commercial designations for wide flange beams with DIN profiles.
  • the free space between at least two spaced wide flange beams is then filled with acoustically effective sound absorbers in the form of cassettes and clamped, so that ultimately a more or less solid noise protection wall arises.
  • the noise protection wall created in this way usually has a height of 2.0 to 20.0 meters. They stand, stand alongside permanent and/or periodically occurring sources of noise, such as railway lines, motorways, sports facilities, commercial areas, etc., but are also often freely accessible to all types of passers-by.
  • the repair i.e. the replacement of the noise protection elements
  • the lower noise protection wall area mentioned is very complex, labor-intensive and therefore also very expensive.
  • the removal and installation of the previously undamaged elements results in damage to these elements.
  • rubber seals, supports and screw connections must be regularly replaced up to the full wall height. For this reason, necessary renovations are reduced to an absolutely necessary level and even getting used to an actual state that is basically unacceptable according to general understanding is accepted, since the restoration costs are too high.
  • At least one noise protection element with a support frame which is designed in such a way that it can be inserted in a form-fitting manner between the spaced wide flange girders and comprises two vertical frame rods and two horizontal bars, the support frame having a groove running around its inner edge, in which an acoustically effective filling designed as a planar structure can be inserted in a form-fitting manner.
  • noise protection wall helps to significantly reduce the effort required for maintenance.
  • the turnaround in noise protection separates landscapes and paths. Due to this reality of life, noise protection walls were not completed until any kind of construction work on one side or the other of the noise protection turnaround had been completed. With the present invention, however, it is now possible to set up the entire support structure completely and still allow a passage or passage. Once all work is complete, a small team can install the acoustically effective insulation or filling without having to use heavy equipment.
  • the support frame has a quadrangular view.
  • other geometric figures/views are also conceivable and can be looked up by a person familiar with the subject physical/technical and also aesthetic aspects can be chosen freely.
  • the actual size of the support frame can also be freely adapted to the local conditions at the installation site.
  • the acoustically effective filling terminates flush with the surface of the support frame. This does not rule out the possibility that the acoustic filling in the area that is not assigned to the supporting frame can have a surface profile that protrudes beyond the surface of the supporting frame. Thus, acoustically active profiles of the acoustically active filling are possible and also desirable.
  • the acoustically effective filling is designed to be clampable by means of a holding frame in the circumferential groove of the supporting frame and flush in this area with the surface of the supporting frame.
  • this does not rule out the possibility that the acoustic filling in the area that is not assigned to the holding frame and is covered by it can have a surface profile that protrudes beyond the surface of the holding frame.
  • acoustically active profiles of the acoustically active filling are possible and also desired.
  • the holding frame is compared to the support frame by means of suitable Locked screwing, the screwing should be flush with the surface of the support frame.
  • the screwing means can be custom-made products that also have a screwing means head that makes it considerably more difficult, if not impossible, to use standard opening means. This avoids improper and/or unauthorized removal of the acoustically effective filling from the support frame and means that only authorized personnel can carry out maintenance work on the noise protection wall.
  • the acoustically effective filling consists of a biogenic material, a mineral material, in particular expanded concrete materials, a transparent material, in particular glass or plastics such as Plexiglas or translucent plastics or polycarbonate.
  • a biogenic material e.g., a biogenic material, a mineral material, in particular expanded concrete materials, a transparent material, in particular glass or plastics such as Plexiglas or translucent plastics or polycarbonate.
  • a transparent material in particular glass or plastics such as Plexiglas or translucent plastics or polycarbonate.
  • suitable recycling material are also conceivable.
  • the support frame and the holding frame can be made of mild steel, a wood material or a plastic. Recycled materials are also conceivable here.
  • the noise protection wall 10 essentially comprises at least two spaced-apart wide flange beams 11, 11a.
  • a noise protection element 12 is arranged between the wide flange supports 11, 11a.
  • the noise protection element 11 comprises a supporting frame 13 which is provided with an acoustically effective filling 15 .
  • the support frame 13 consists of vertical frame rods 18, 18a and horizontal bars 19, 19a, which together form the support frame 13.
  • the acoustically effective filling 15 is placed in a form-fitting manner in a circumferential groove 14 arranged on the inner edge 20 of the support frame 13 .
  • a holding frame 16 is provided which essentially has the overall width of the groove 14 and is flush with the inner edge 20 of the support frame 13 in the working position.
  • the acoustically effective filling 15 is clamped between the supporting frame 13 and the holding frame 16 .
  • the holding frame 16 closes with its surface 22 in a form-fitting manner with the surface 21 of the support frame 13 .
  • the holding frame 16 and thus also the acoustically effective filling 15 are detachably fixed to the supporting frame 13 by means of screwing means 17 .
  • the screwing means 17 can be inserted and screwed into aligned bores (not shown) provided in the supporting frame 13, the auxiliary frame 16 and the acoustically effective filling 15.
