Definitions

  • the present invention relates to a sound absorbent panel for covering walls, ceilings and floors of rooms and premises and to a manufacturing method of said panel.
  • the main drawback of said known elements consists in their weight and encumbrance, due to the high thickness required to achieve a suitable insulation and in the need to cover said elements to confer them an acceptable aesthetical aspect.
  • the main drawback of said known panels consists in that they provide an inadequate sound proofing and insufficient reduction of the echo.
  • the drawback of the known panel manufacturing methods consists in that the known elements are very expensive, because of the manufacturing complexity for carrying out protrusion and/or cavities.
  • Document DE622470 discloses a sound absorbent panel comprising two or more row of spaced apart strips.
  • Document EP0745738 discloses an acoustic panel made from a triple-layered solid wooden board with two cover layers parallel to each other in relation to the fibre direction and one centre layer running across it.
  • the cover layer on the room side has longitudinally aligned slits reaching to the centre layer.
  • the centre layer has on its side facing this slit layer grooves crossing the slits.
  • the grooves and slits criss-cross at right angles.
  • the slits and/or grooves can have a rectangular, rounded, triangular or chamfered cross- section.
  • the other cover layer can also have slits aligned with those of the room-facing layer.
  • Document AT 6097 U1 and document JP-A-02178447 disclose a panel a face of which has grooves parallel each other and with depth smaller than the thickness of the plate and bigger than half of said thickness.
  • the other face has identica! grooves orthogonal to the grooves of the first mentioned face.
  • the crosses of grooves form passing holes.
  • Document JP-A-02178447 further discloses (see Figure 8) a sound absorbing decorative panel made of two plate body each with respective grooves formed at preset interval and with the depth of the grooves on one face of each plate body reaching nearly one half of the thickness of the plate body.
  • the plate body are stuck while the respective grooves are matched with each other forming hollow stripe holes.
  • the grooves on the opposite face of one of the plate bodies have a depth equal to the thickness of this plate body.
  • the features of this panel correspond to those of the preamble of claim 1.
  • the main object of the present invention is to propose a sound absorbent panel, and a manufacturing method of said panel, having high soundproofing and echo reduction characteristic, the panel being easy and quick to be built.
  • Another object is to propose a flexible sound absorbent panel, which can be adjust to surfaces and/or walls curved or with complex geometries, which has a pleasant superficial aspect and is aesthetically agreeable, and which does not require covers or further decorative treatments.
  • numeral 1 indicates a sound absorbent panel of the present invention, including two facing plates 2, each of which provided with a plurality of parallel grooves first 5 and seconds 6, respectively carried out in the opposed faces first 3 and second 4 of each plate 2. Particularly, the two plates are mutually fixed, by sticking the respective seconds faces 4.
  • the grooves first 5 and second 6 of each plate 2 are partially intersecting, and they carry out through openings 8 in said plate 2 at each intersection.
  • the first grooves 5 have a depth equal to the thickness of the corresponding plate 2, while the second grooves 6 have a depth ranging between around a fifth and around four fifths of the thickness of corresponding plate 2.
  • the first 5 and second 6 grooves are almost orthogonal each to other and they have a cross section with rectangular or "V" or "U” or polygonal shape.
  • first grooves 5 of a plate 2 are off-set with respect to the first grooves 5 of the remaining plate 2.
  • the grooves 5, 6 of a plate 2 can form with the corresponding grooves 5, 6 of the other plate 2 an angle ranging approximately between 0° and 90°.
  • the two plates 2 are made of wood or its by-products and it is provided that at least the first face 3 of each plate 2 is covered with a sheet of faced material, or is lacquered or painted.
  • the figures 3 , 4 and 5 show a variant of the sound absorbent panel 1 including a layer 7 of flexible material, interposed between the two plates 2 and fixed thereto through bonding agent.
  • the flexible material is constituted by fabric or nonwoven fabric or a plate made of rubbery or spongy material, or a lead sheet or an high density sheet.
  • the first grooves 5 of a plate 2 fit together with the first grooves 5 of the remaining plate 2, in such a way to confer to panel 1 flexibility and therefore the capacity to be bent and adapted for an application on curved or shaped surfaces.
  • the first grooves 5 have preferably a "V" cross-section.
  • the figure 6 shows a further variant of the sound absorbent panel constituted by three superimposed plates 2 having off-set grooves 5, 6.
  • the manufacturing method of this sound absorbent panel 1 provides:
  • the method further provides to carry out first grooves 5 of each plate 2 having a depth equal to the thickness of said plate 2 and positioned almost orthogonal with respect to the second grooves 6.
  • the manufacturing method further provides to joint together the two plates 2 by means of a layer of flexible material 7 and to fix said layer of flexible material 7 to the two plates 2 by sticking.
  • the first grooves 5 of a plate 2 are carried out facing the first grooves 5 of the other plate 2 in order to give flexibility to the panel 1.
  • the main advantage of the present invention is to provide a sound absorbent panel and a related manufacturing method having high sound absorbing characteristics and echo reduction, and easy and quick to be built.
