Definitions

  • the present invention relates to a sound and vibration damping device using absorbent elements arranged in at least one non-combustible box, so as to delimit elementary deaf chambers, said box comprising a so-called "front" wall provided with openings intended to be in look from a source of noise.
  • a device of this type is known from FR 2 612 217.
  • the absorbent elements consist of a fibrous mat and the boxes are prefabricated boxes made of concrete reinforced with glass fibers or made of resin concrete.
  • the present invention aims to provide a sound and vibration damping device of the aforementioned type overcoming the drawbacks set out above, while improving the acoustic damping capacities.
  • the present invention relates to a sound and vibration damping device which is characterized in that said elements are unitary structures made up of tires, parts of tires or equivalent elements in terms of shape and absorbent nature of the material, in that said unitary structures are clamped against one another and / or one on the other between walls of said box and in that the shape of said unitary structures is adapted according to their orientation in said box, create a focusing or diverging effect of the acoustic waves.
  • the aesthetic appearance is fixed by the box walls which can be decorated or arranged at will according to aesthetic wishes.
  • the elementary deaf rooms constituted by the unitary structures, cause an effect of trapping acoustic waves by the shape of said structures.
  • the holes or gills can advantageously be replaced or supplemented by flaps made up of articulated or fixed blades replacing, or completing, said front wall provided with openings.
  • the evacuation of rainwater or washing of the half-tires is done by gravity.
  • One of the particularities of an assembly thus constituted is to provide a damper function for mechanical vibrations and to attenuate the noise level generated by the passage of vehicles, cars, trucks, trains, etc., but also for environmental protection near noisy areas (factories).
  • the side walls 3, the cover 4 and the bottom 5 of the box C1 can be separated from any other non-combustible or non-metallic parts, ensuring the rigidity of the assembly, by flexible joints.
  • the front panel 6, on the noise source side is perforated with holes 7, shutters or gills of suitable shapes, to promote the penetration of sound waves inside the device. It can also be made of expanded metal.
  • the panels and walls constituting the fire box can be flat, wavy, ribbed or of suitable shapes to increase the rigidity of the assembly.
  • FIGS. 3 and 4 are views similar to the previous ones, but this time the box C2 has a rear panel 2 'joined to the side walls 3' by oblique intermediate walls 16, so that the box C2 has, in cross section, a trapezoidal part.
  • Axial or inclined flaps 8 and separation plates 9 of absorbent material have been judiciously arranged, the first 8 on the front face of the box C2, the second 9 between the half-tires 1, so that the reflected waves, focused by the form tires, meet absorption surfaces as large as possible.
  • the panel where the flaps 8 are fixed can replace or supplement the perforated panel 6 of FIGS. 1 and 2.
  • the flaps 8 and the plates 9 can be replaced by an absorbent cellular structure, or any equivalent.
  • FIGS. 5 and 6 represent half-tires 1, drilled or not, porous or not, according to another mode of installation, put in place in the fire protection boxes C1 with their tread 19 on the front face side of the box, and their open section 20 on the rear panel side, to create a diverging reflection of the acoustic waves.
  • Half tires porous or pierced with orifices 10 make it possible to channel, inside the tire, part of the sounds, the other part being reflected with diverging effect.
  • Figures 7 and 8 show an installation mode corresponding substantially to a redoubling of that of Figures 1 and 2: two columns of half-tires 1 'and 1' 'are juxtaposed and separated by a porous or absorbent wall 11, maintained on the side walls 3 '' of the fire protection box C3, the half-tires 1 'being preferably porous or drilled, so that the acoustic waves coming into contact with them are trapped in the deaf chamber 13, by transmission or reflection, the unabsorbed part of the waves being reflected with focusing effect.
  • FIGS. 9 and 10 show a method of installation corresponding substantially to a repetition of that of FIGS. 5 and 6, repetition similar to that of FIGS. 7 and 8.
  • Figures 11 and 12 represent a hybrid installation mode between that of Figures 9 and 10 and that of Figures 11 and 12: instead of being oriented in the same way, the half-tires 1 'and 1' 'are oriented in the opposite direction.
  • Figures 13 and 14 show the assembly of whole tires 18 in a vertical stack between the rear 2 and front panels 6.
  • the tires 18 are in contact with each other by their tread 19 and one of their lateral face 21 is in look at the noise source.
  • the central parts of the tires can receive absorbent, planar, concave 15 or convex 15 'flanges, or of any other shape favoring the penetration of sounds towards the interior of the tires, with divergence or focusing effect given by the shape of the flanges.
  • a porous or absorbent wall 17 being placed against the rear panel 2 in order to ensure the transmission and absorption effect between the tires.
  • Figure 15 shows a similar installation mode to the previous one, but with two columns of whole tires 18 'and 18''juxtaposed, the flanges 15 being preferably drilled in order to allow the passage of sounds up to the absorbent wall 11, the volume behind this wall which contains the second column of 18 '' tires, playing the effect of a 13 'deaf chamber.
  • the fire-resistant cabinets or boxes, thus formed, juxtaposed with each other, constitute an anti-noise wall which can be built vertically or inclined.
  • One of the methods of installing noise barriers, at the edge of roads, motorways and railways may consist, for example, of fixing juxtaposed fire-resistant boxes, integral with one another, on a flat or profiled cross member, placed at least 2/3 of the height, laterally, on the rear panel 2, of the caissons, and fixed to posts anchored in the ground, this cross-member being able to be reinforced by a strut.
