Definitions

  • the present invention relates to soundproofing materials and particularly it refers 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.
  • 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, or they are reciprocally interfering, 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
  • 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 a 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.
