Definitions

  • the present invention relates to a roller skating track at low acoustic radiation and an acoustic complex corresponding. It concerns not only the planned tracks for roller skates, but also more generally all tracks designed for non-motorized vehicles on casters or wheels. Of such devices may include boards or skates, such as for example skateboards or skates casters, or consist of bicycles.
  • the expression "runway roller skating ”thus generically designates any track of this type.
  • the track includes thus a metal layer and a layer of laminated wood, the two layers being spaced apart by means of spacers, so forming an intermediate vacuum having a thickness that is substantially equal to that of the metallic layer.
  • the present invention relates to a low roller skating track acoustic radiation, easy to use and economical can be stable over time, and can mitigate considerably the acoustic radiation of the runway.
  • the invention also relates to an acoustic complex corresponding.
  • the viscoelastic layer has a surface density of between 3 and 10 kg / m 2 and preferably approximately equal to 8 kg / m 2 .
  • the layer viscoelastic consists of flexible self-adhesive plates.
  • bituminous paint In a second preferred embodiment, it is made of bituminous paint.
  • the acoustic complex also includes a waterproof support placed between the bituminous paint and the layer of wool.
  • this support waterproof, it is made of glass cloth. In a second embodiment, it consists of a layer of cork, having preferably a thickness between 15 and 25 mm.
  • the layer of mineral wool has a thickness between 20 and 70 mm, and more particularly between 40 and 60 mm.
  • the acoustic complex includes also a metallic structure placed under the layer of wool mineral.
  • Such a screen reduces the risk of vandalism. he is fixed, for example, by means of fixing bars arranged under the fence and themselves fixed laterally to the structure of contact.
  • the invention also relates to an acoustic complex for roller skating track according to the invention.
  • a roller skating track 20 includes ( Figure 1) schematically a module 51 and two side modules 52 and 53.
  • the module 51 has two curved portions 22 and 23 opposite concaves and interconnected by an upper bearing 21.
  • Each of the modules side 52 and 53 respectively have a portion curved 26 and 27 concave opposite the central module 51, surmounted by an upper level 24 and 25. From users of machines to castors or wheels mount on the bearing 24 or 25 of one of the side modules 52 or 53 by any means such as staircase, and slide with their rolling machines on one of the curved parts 26 or 27. They thus arrive with speed on one of the curved parts 22 or 23 of the central module 51.
  • the side modules 52 and 53 have for example on the side opposite the curved part 26 or 27 a vertical wall or a staircase.
  • the track only has the central module 51 and one of the side modules 52 or 53.
  • Runway 20 essentially comprises a structure of contact 1 and an acoustic complex 10 attached below the contact structure 1.
  • the acoustic complex covers the entire surface of the contact structure, in each of modules 51 to 53.
  • Contact structure 1 is a traditional structure for roller skating track, and can be made of polyester, wood or stainless steel.
  • the set of flexible plates 2 has, for example, a surface density of 8 kg / m 2 and can be obtained from SOPREMA Establishments.
  • Mineral wool 3 is, for example, formed of panels such as those marketed by Isover Saint-Gobain Establishments under the name PROTISOL, ACOUSTIBEL or equivalent.
  • This layer 3 lines the set of flexible plates 2 and has, for example, a thickness of 50 mm. It is attached to the contact structure 1 by means of fastening elements such as rosettes 4 or in pose glued by self-adhesive strips, also available from Isover Saint-Gobain establishments. These rosettes 4 are advantageously placed approximately all the 20 to 40 cm, long and wide of the acoustic complex 10.
  • This layer 3 of mineral wool is preferably not hydrophilic.
  • the metal structure5 is made up, in a form of production of aluminum foil. In another form of realization, it is formed in steel plate.
  • This metal structure 5 is fixed ( Figures 2 and 3) to the contact structure 1 by fixing bars 6 arranged at the opposite of the contact structure 1. These bars 6 are by example held laterally by brackets 7 at edges side (not shown), by means of bolts 9. Bars 6 and the bolts 9 are preferably made of stainless steel.
  • the bars 6 are also fixed directly to the metal structure 5 by others brackets.
  • the track referenced 20B has its acoustic complex referenced 10B which differs from the acoustic complex 10A, in particular by the fact that the viscoelastic layer consists of a bituminous paint 11.
  • This bituminous paint 11 for example, has a surface density of between 6 kg / m 2 and 9kg / m 2 (as for the first embodiment) and can be obtained from Bitumastic Establishments.
  • a waterproof support is interposed between the paint bituminous 11 and layer 3 of mineral wool, this support being for example consisting of cork, such as that sold under the name Isorel.
  • This cork then has, for example, a thickness of 10 mm.
  • the waterproof support is made of glass cloth.
  • layer 3 of mineral wool is covered with a thickness of polyane 13. This thickness makes it possible to avoid defibration and possibly reduce the effects of moisture.
  • any one of the two embodiments of Figures 2 to 4 by projecting acoustic paint at the start of the runway, such as, for example, that marketed by Establishments Bitumastic.
  • a sound level meter was installed at four measurement points 41 and 42 (near building 31), 43 (building 32) and 44 (building 33). We then noted in each of these points 41-44 the value average noise level Leq and maximum Lmax, in background noise and in ambient noise (runway noise in operation). Measures were carried out over a period of 30 minutes at each point of measurement, under intensive conditions of use.
