Definitions

  • the invention relates to a sound-damping wall for arrangement alongside a railroad or highway.
  • Sound-damping walls are known in many designs, such as e.g. the vegetation screens according to EP-C-0128245, which are also executed in the shape of an inverted V, in particular for use with a railroad, such as according to EP-C-0265991.
  • Other types of walls are also used, in which plastic sheets and the like are employed. In these last cases, it mostly concerns walls only reflecting sound so that it is less able to penetrate into the surroundings of the railroad or highway.
  • vegetation screens have the advantage that they largely absorb sound, it is a disadvantage that they require relatively much maintenance. Further, in particular with the inverted V-shape, they require much space for arrangement, which will not always be available.
  • the invention aims to remove these difficulties and to that end provides for a sound-damping wall characterized in that it is composed of substantially rectangular panels having a substantially rectangular cross-section, with the one transverse wall of a panel having a longitudinally extending, almost C-shaped portion and the other transverse wall being formed such, that a protruding part thereof can be matingly received in the C-shaped portion of a subsequent panel, at least one longitudinal wall of a panel being provided with a perforation.
  • Such a panel can be manufactured at low cost from recycled plastic and in any desired color, or transparent. Manufacture from ceramic material or metal, aluminium for example, is also possible.
  • the panels can be slid together in longitudinal direction so that a continuous sound-damping wall will arise.
  • the engaging parts of the transverse panels provide acoustically completely sealed-off walls.
  • the transverse walls can form an angle between 2 and 10° to a plane square to the longitudinal walls, in such a way that they enclose a sharp angle between each other.
  • the angle between a transverse wall and the plane square to the longitudinal walls will be approximately 5°.
  • the subsequent transverse walls are provided with a number of aligned openings through which an elongated member being square to said transverse walls can be slid.
  • the openings will be in the shape of slots being transversely to the longitudinal direction of the transverse wall and extending up to the longitudinal walls of the panel and the elongated member will be a strip. The strip will then almost lie against the inner side of the longitudinal walls.
  • the strips will cause the subsequent panels to lie exactly in one plane. Therefore, the tolerances in the dimensions of the engaging portions of the panels can be accomodated. At the same time the strips will serve for absorbing the transverse forces, such as exerted by the wind, acting on the panels. Due to this, overload of the connecting elements of said panels and bending of an assembly of sheets can be prevented.
  • the strips By applying the strips also the upper edges of a number of mutually connected panels are aligned so that an esthetic unity is obtained.
  • the position of such an assembly can also be adapted when the foundation of a number of such assemblies on one location would be slightly more subsided than on another location.
  • posts which are anchored to the ground and which are designed such that they can be received in the cavity of a panel.
  • the posts will generally be made of metal and are, after mounting panels thereon, invisible from the outside and protected against weather influences. Due to this, grounding of the metal parts may be unnecessary.
  • the panels can also extend in horizontal direction such as for establishing a sound screen over a railroad or highway, in which the sound screen is curved upwards over a road.
  • the transverse walls of the panels will have to be supported by constructional elements enclosing them. Said elements can be anchored to the ground.
  • the panels can be partly or completely filled with a sound-absorbing material, such as in the form of mineral wool.
  • the sound-absorbing material can be applied on this wall.
  • the sound-absorbing material can also be a substrate suitable for having plants grown therein. This can improve the appearance of the screen.
  • partition wall in a panel, said partition wall being parallel to the longitudinal walls of the panel and being provided with a layer of sound-absorbing material on at least one side.
  • the wall can also serve as earth-retaining structure and not be intended only for absorbing vibrations.
  • the wall can also serve as earth-retaining structure and not be intended only for absorbing vibrations.
  • only one longitudinal wall will be provided with a perforation.
  • the drawing shows a panel 1 consisting of the longitudinal walls 2 and the transverse walls 3 and 4.
  • the transverse wall 3 is provided with a C-shaped portion 5 in which a protruding portion 6 connected to said transverse wall 4 can be fittingly received. Owing to this, said elements can not be pulled apart.
  • the transverse walls 3 and 4 are not square to the longitudinal walls 2, but can enclose an angle ⁇ with a plane 7 being square to the longitudinal walls. Due to this, the transverse walls will enclose an angle twice as large.
  • the angle ⁇ will preferably be about 5°, but can of course also have another value, depending on the application of the panels 1.
  • the longitudinal walls 2 are additionally supported in relation to each other by one or more intermediate transverse walls 8. At least one of the longitudinal walls 2 is provided with perforations 9.
  • the dimensions of the openings concerned can be adapted to the purpose. Generally, however, one and the same perforation can be used for various purposes.
  • a panel 1 can be slid onto a post 10 which is anchored to the ground 12 by means of a baseplate 11. A number of panels can then be mutually connected and the last panel of a series can be mounted on a post 10.
  • slots 13 For supporting the series of panels, slots 13 have been provided in the transverse walls 3, 4 and 8, in which strips 14 can be received, which then almost contact the longitudinal walls 2.
  • the series of panels 1 can then offer more resistance to the wind load or another load.
  • a dividing wall 16 being provided with a sound-absorbing material 17 such as mineral wool, for example, can be mounted in its cavity 15. This material will be situated at a longitudinal wall 2 provided with perforations 9. Naturally, the other longitudinal wall of a panel 1 can be provided with perforations too and then the other side of the dividing wall 16 can be provided with a sound-absorbing material. In this case, the wall will be double-acting. In order to fix the dividing wall 16 in its place, slots 18 have been provided in the transverse walls 18.
