Definitions

  • This invention relates to a soundproof panel for building applications, preferably to insulate or deaden sound waves emitted in a domestic or industrial environment, more particularly a soundproof panel comprising slabs of plasterboard or plasterboard-like material and which can be applied to existing walls or roof slabs, in order to define a counterwall, a partition wall, or a false ceiling.
  • Soundproof panels used in the construction sector and applicable to existing walls or roof slabs to define counterwalls, partition walls, or false ceilings are known.
  • the soundproof panels of this type comprise:
  • the containment structure is interposed between the existing wall and the soundproof layers, usually with a gap of air between the existing wall and the containment structure.
  • additional plasterboard slabs are arranged to cover the containment structure to define an additional external surface of the panel designed to be struck by sound waves emitted by an additional acoustic source.
  • the fixing frame typically comprises a metal profile, usually having a flange or central core and at least one wing extending from the flange and arranged at a perimeter edge of the panel, thus defining a perimeter edge element of the same.
  • the profile has a U-shaped (or C-shaped) cross-section with a central flange and two wings projecting from the latter.
  • the sound-absorbing layers are inserted into the metal profile, so that the metal profile defines a perimeter edge element for the sound-absorbing layers, leaving the plasterboard free to the side, so that the latter may be arranged resting to the side directly on the walls (for example, the ceiling and the floor) orthogonal to the existing wall to be covered.
  • the plasterboard or plasterboard-like material slabs are rigidly fixed to one of the wings (or to both, in the case of partition walls) of the metal profile; the central flange of the metal profile is, in turn, rigidly fixed to the existing wall.
  • the central flange of the metal profile is fixed to the existing walls that will be orthogonal to the partition wall when assembled.
  • the fixing frame also comprises multiple hangers fixed, on one side, to the containment structure and to the layers of sound-absorbing material, and on the opposite side to the existing roof slab, while the metal profile is fixed, at its central flange, to the existing walls that support this roof slab.
  • the plasterboard slabs are coupled to the frame, i.e. to the wing of the metal profile, via first plugs or similar clamping means.
  • the Applicant has proven that the soundproof performance of the panels of the type described above does not depend solely on the nature of the sound-absorbing material and the thickness of the sound-absorbing layers, but also on the coupling interface between the panel and the existing walls adjacent to the wall or roof slab to be insulated.
  • the Applicant has been able to verify that the first plugs used for fixing the plasterboard slabs to the frame (metal profile) and the second plugs used to fix the frame to the existing wall/s define unwanted passages for transmitting vibrations and, thus, for sound waves.
  • the sound waves break on the plasterboard slabs, making them vibrate. Despite the presence of the sound-absorbing layers, part of the vibrations produced is transmitted to the metal profile through the first plugs, and from the metal profile to the existing walls through the second plugs.
  • the purpose of this invention is to produce a soundproof panel for building applications which is highly reliable and inexpensive, and makes it possible to avoid at least some of the drawbacks specified above and connected to known soundproof panels for building applications.
  • the reference number 1 indicates, as a whole, a soundproof panel for building applications to insulate or deaden sound waves emitted in a domestic or industrial environment, especially a soundproof panel 1 that can be applied to existing walls or roof slabs in order to define a counterwall, a partition wall, or a false ceiling to which panel 1 this description will refer without any loss of generality thereby.
  • the panel 1 is designed to be fixed to at least one existing wall 2, in particular two existing walls 2 parallel to each other, in order to define a counterwall covering a wall 3 to be insulated that is transversal to the existing walls 2.

  • the panel 1 comprises a pair of slabs 4 arranged axially resting on each other with the interposition of a layer of damping material 7 (below, a "damping layer 7"), preferably made of polymer-plastic-based bituminate or EPDM rubber.
  • a layer of damping material 7 preferably made of polymer-plastic-based bituminate or EPDM rubber.
  • these slabs 4 are arranged so that the front surface 4a of a slab 4 rests on the rear surface 4b of the other slab 4, with the interposition of the damping layer 7.
  • the pair of slabs 4 defines a single external, protecting construction element, having an external surface corresponding to the front surface 4a of a slab 4 and an internal surface corresponding to the rear surface 4b of the other slab 4 and a lateral surface corresponding to the adjacent lateral surfaces 4c of both slabs 4, with the interposition of the damping layer 7.
  • the pair of slabs 4, with the interposed damping layer 7, will be considered as the above-mentioned single construction element, and, therefore, solely the external, internal, and lateral surfaces of the latter will be indicated, to be understood as the front 4a, rear 4b, and lateral 4c surfaces.

  • the frame 6 comprises a metal profile 8 defining at least part of a perimeter edge of the panel 1.
  • the perimeter edge of the panel 1 can be defined as the edge of the panel facing, in use, the existing walls 2.
  • the profile 8 has a U-shaped (or C-shaped) cross-section and comprises a central flange 10 and two wings 11.

  • the profile 8 surrounds the peripheral portion 55 and the sound-absorbing layer 5 is inserted in the profile 8 with the lateral surface 5c abutting against the internal surface 10b of the flange 10.
  • the slabs 4, together with the damping layer 7, are rigidly fixed to one of the wings 11 of the profile 8, as schematically illustrated in Figure 2 .
  • this fixing is carried out by means of plugs.
  • other, similar fixing means could be used.
  • the profile 8 is designed to be fixed to the existing walls 2, in particular by means of plugs as schematically illustrated in Figure 2 .
  • the flange 10 is designed to be fixed to the existing walls 2 using a series of plugs, to determine the fixing of the panel 1 to the existing walls 2 and the covering of the wall 3 to be insulated.
  • the sound-absorbing layer 5 is arranged outside the space delimited between the wings 11, i.e., it is arranged on the opposite side of the profile 8 in relation to the slabs 4, preferably fixed (for example glued) to the other wing 11, or glued, when assembled, to the wall 3 to be insulated.
  • the panel 1 also comprises a first layer of anti-vibration material 12 (below, an "anti-vibration layer 12") coupled to the profile 8 at the flange 10 and extending to completely cover the perimeter edge of the panel 1 so as to be interposed, when assembled, between the flange 10 and the existing walls 2, between the lateral surface 4c and the existing walls 2, and between the lateral surface 5c and the existing walls 2.

  • the anti-vibration layer 12 also covers the lateral surface 5c (as in the case illustrated in Figure 5 , which will be discussed below).
