Definitions

  • Sound absorbing screens and walls consisting of several surfaces pierced with openings, except that on the side opposite that of the road, which is full, and separated by empty spaces.
  • the subject of the present invention is a sound absorbing wall, in particular for motorways, consisting of a resonator structure whose cavity is subdivided, in the direction of the depth, into at least two cavities communicating with each other, the first cavity, facing the noise source, being open on the road side, the last cavity being closed on the side opposite the road and communicating only with the penultimate cavity, characterized in that these cavities are formed by independent prefabricated panels, in reinforced concrete, fiberglass concrete, terracotta, fiber cement, plastic or any other material that is easy to maintain, having substantially the same geometric dimensions, the lateral sides of which are engaged in substantially vertical, U-shaped slides, provided for this purpose in pillars sealed in the ground along the highway, the interval between two successive pillars being such that the panels can grout ser freely in said slides, in which these are introduced from above, the panels resting directly or through a sole on the ground, in seems cavities being closed up by a cover.
  • the openings of these panels are preferably bevelled, the obliquity of the bevel being of the order of 30 ° maximum for the thickest panels, and may be zero for the thinnest panels; the bevels of the first panel are convergent, and those of the penultimate panel are divergent.
  • the open area of the first panel is preferably greater than 50%; the proportions of the open surfaces of the successive panels decrease from one to the other, that of each of them possibly being, for example, half that of the following panel.
  • the shape of the beveled openings can be arbitrary (circular, square, ovoid, rectangular in the vertical or horizontal direction, or any other) as well as their size and their arrangement.
  • the wall shown in FIG. 1 comprises four successive panels 1 to 4.
  • the first panel 1 is pierced with openings 5 shown square, the edges 6 of which are bevelled, the obliquity of the bevel being of the order of 30 °, and these bevels being convergent; the surface of these openings is approximately 50% of the total surface of the panel, which can for example be 5 m long by 1 m high, its thickness being 50 mm.
  • the last panel 4 is. full. In the drawing, it has been assumed that the interval between the first and second panels, and thus, between the second and third panels, is .; equal to 80 mm, while the interval between the last panel 3 and the solid panel 4. is only 20 mm.
  • These panels can be manufactured in the factory and brought to the site for use; the panels of each category are superimposed on each other, sliding their ends in U-shaped grooves, 10, 11, 12 and 13, which can be provided for this purpose in successive pillars 14, 15 and 16 , embedded in the ground, or in the surface that supports the wall; these pillars may themselves have recesses, or any other arrangement, having the double advantage of lightening them and allowing them to constitute phonic screens themselves.
  • This sound absorbing wall can also be produced in the form of modular bricks, of a few square decimetres of surface, which can be used, for example, for the coating of deaf rooms; each brick then consists of three or four walls parallel to the coated plane, the first or three first walls being provided with openings arranged as indicated above, the last wall being full; the thickness of the walls can then be between 5 and 20 mm for example, the openings can still be bevelled. some of the cavities in the brick can be filled with fibrous products; the Bricks are then assembled by masonry joints or by any other process capable of linking together these modular elements.
  • the absorption coefficient (Sabine) of such sound walls measured with a Kundt tube, oscillates around an average value of 0.90, for a frequency range between 160Hz and 1250 Hz.
  • the wall is, as before, made up of four successive panels 17 to 20, but their edges are secured by a molded frame, made of cement or reinforced concrete, for example, with a sole 21 at the bottom, side uprights 22 and 23, and a beam 24 at the top, so as to constitute a rigid welded assembly, preferably provided with lifting means; likely to be manufactured in the factory, or on the site itself, and to be placed between two successive pillars, these then preferably being made up of commercial I-shaped metal profiles.
  • a molded frame made of cement or reinforced concrete, for example, with a sole 21 at the bottom, side uprights 22 and 23, and a beam 24 at the top, so as to constitute a rigid welded assembly, preferably provided with lifting means; likely to be manufactured in the factory, or on the site itself, and to be placed between two successive pillars, these then preferably being made up of commercial I-shaped metal profiles.
  • the panel 17, road side consists of decorative modules 25, four for example, removably attached to the frame, by screws or any other means; this mobility allows the change or cleaning of the sound absorbing fibrous product 26, disposed between the first road side panel 17 and the second panel 18; it also allows the modules 25 to be changed if they are damaged, or for aesthetic reasons; the four modules forming the panel 17 may be of different designs, or these modules may be different from one panel 17 to another.
  • the rigid assembly constituted by the four panels 17 to 20, secured by their frame 21 to 24, can be slid from top to bottom between the wings 27 and 28 of the consecutive pillars 29 and 30 constituted, in the es ce, by commercial I-profiles.
