Definitions

  • thermo-acoustic insulating structure for cladding, or other non-load-bearing wall, comprising a thermally insulating panel held between metallic coatings, respectively internal and external, provided with ribs projecting from the panel, the ribs of the two coatings being perpendicular. between them.
  • the two main factors of the acoustic weakening are the volumetric mass of the structure and, consequently, the density and the thickness of the various components, and the distance between the successive components.
  • a known insulating structure (FR-A-1 288 854), comprising a thermal insulator maintained between two metallic coatings, absorbs insufficiently the internal noises if the internal coating is not perforated, but this perforation reduces the weakening of external noise.
  • a significant improvement in insulation is obtained by giving the internal coating the form of a closed box containing a high density insulation (FR-A-2 415 696), but this improvement is limited by the requirements of lightness and low space, when it is a cladding or the like.
  • the present invention therefore aims to solve this problem by improving the insulation qualities of known structures without significantly increasing their weight or their thickness.
  • the object of this invention is in fact an insulating structure of the type in which a thermally insulating panel is held between metallic coatings, respectively internal and external, provided with ribs projecting from the panel, the ribs of each coating being perpendicular to those of the other, which comprises a thin core, for example having a thickness of the order of 2 to 4 mm, of insulating material, applied by a full and thin metal sheet, preferably a sheet of 1 mm (10 / 10th), against a full plate of one of the coatings.
  • the thin core has a laminated structure, elastic, and having a high resistance to the passage of air.
  • the metal sheet is thin and it is fixed to the core only by its attachment to the covering, that is to say at the level of the ribs, the core being only pinched at these points so that it does not not likely to work in shear.
  • the core and the sheet can be placed on the external covering, the sheet then having ribs similar to those of this covering which fit into them, or be mounted on the internal covering between it and the insulation. thermal.
  • the insulating structure comprises an internal covering 1 and an external covering or tank 2 between which is held a panel made of thermally insulating material 4.
  • the internal coating 1 is constituted by a series of U-section plates, nested one after the other.
  • the lateral wings 6 of each of the plates 1 a, 1 b, are folded at their free end, all in the same direction so as to be able to hang on the wings of the adjacent plate.
  • the bottom of each plate is provided with ribs 8, parallel to the wings 6 and projecting in the same direction.
  • the outer tank 2 On the opposite face of the panel 4 the outer tank 2 is constituted by a relatively thin sheet metal, provided with ribs 10 projecting in the direction of the panel 4 and in contact therewith, but perpendicular to the ribs 8 and wings 6 of the covering 1.
  • the interior coverings 1 and exterior coverings 2 are fixed to each other locally, at the crossing points of the ribs 10 and wings 6, so as to ensure the assembly of the structure.
  • the insulating structure further comprises a thin core 12 which covers the outer surface of the covering 2 by conforming to its shape, that is to say by penetrating into the ribs 10.
  • the core 12 is preferably made of a veil of glass fibers having a laminated structure, that is to say comprising several layers, in fa to show great resistance to air.
  • This veil 12 is itself covered by a thin sheet 14 of steel, or other similar metal, provided with ribs 16 similar to the ribs 10 of the tank 2 and fitting into them.
  • the core 12 is thus pinched between the ribs 10 and 16 and kept in contact with the tank 2 and the sheet metal 14 without it being necessary to use any fixing means for this.
  • the absence of bonding or other means of securing the core 12 with the sheets 14 or 2 avoids any risk of shearing work of this core which may cause deformations or act on the frequency of resonance of the whole.
  • the veil 12 has a very small thickness, of the order of 2 to 4 mm, and preferably 2 mm.
  • the sheet 14 is preferably a sheet of 1 mm (10 / 10th).
  • this double wall significantly increases the performance of the structure and in particular the acoustic reduction obtained by means of this wall.
  • This attenuation is particularly sensitive to low frequencies since the resonant frequency of the structure is lowered below 100 Hz, that is to say practically below the usual resonant frequencies on the metallic double walls (from 100 to 315 Hz).
  • Such a structure therefore provides effective protection against airborne noise, and this with an increase in weight and small thickness compared to those of known structures.
  • the increase in thickness can also be further reduced, and even practically eliminated, by producing the insulating structure as shown in FIG. 2.
  • a thin core 22 is mounted against the coating 1, between the latter and a thin sheet 24.
  • the thin core 22 is then applied against the ribs 8 of each of the plates 1a, 1b, and curved at its ends against the wings 6 of this tray.
  • the sheet 24, bent at its two ends, is fitted into each plate 1a, 1b, and fixed on the wings 6 of this plate.
  • the panel 4 made of mineral wool felt, or any other thermal insulator, is in contact with the successive sheets 24, on either side of the wings 6 connecting between the various plates.
  • This panel may have the same thickness as that used in the embodiment of FIG. 1 or have a slightly smaller thickness, so as to give the whole of the structure a thickness which is less than that of the structure without a web. of glass and sheet metal 14, the external coating 2 being produced in the same way by means of a thin sheet metal provided with ribs 10.
  • the web 22 is simply pinched between the sheet 24 and the ribs 8 of the covering against which it is placed. No particular means of adhesion or fixing is necessary.
  • Such a structure also meets the lightness requirements of cladding or other facings of buildings and in particular of industrial buildings.
  • this coating is produced in the form of boxes, as shown in the figure 3.
  • Each box of this internal coating then comprises a U-shaped plate, perforated, 31, between the wings 36 of which is fitted a solid sheet 32 which holds a thin panel of high density mineral wool 34, filling the space between the full sheet 32 and the perforated plate 31.
  • the thin core 22 is then mounted against the sheet 32 for closing the box and the sheet 24 maintains this core 22 between the wings 36 of the plate.
  • a panel of mineral wool felt 4, or the like covers the ribs formed by the wings 36 of the successive plates and is protected by an external tank 2 comprising ribs 10 perpendicular to these wings 36.
  • the structure thus produced provides real damping of interior noise thanks to the perforation of the internal plate 31, but has a significant sound reduction index thanks to the combination of the walls 32 and 24 with the thin core 22, which is added to the action of the outer tank 2 and of the insulation 4.
  • This structure which may have a thickness very close to that of the embodiment of FIG. 2, has a very low resonance frequency which no longer interferes with the acoustic attenuation and makes it possible to obtain a curve of weakening which rises in an almost regular way as a function of the frequency, and that starting from frequencies lower than 100 hz.
  • This structure is particularly suitable for making facing or cladding of buildings, or other non-load-bearing walls, intended to be placed on elements of metal or concrete.
  • the plate 1 (fig. 1 and 2) or the box 31 (fig. 3) are mechanically attached to the supporting frame by any suitable means.
  • a flexible joint (polychloroprene type sold under the trademark Neoprene or flexible cellular PVC) can be interposed between the supporting structure and the plate or box in order to reduce the transmission of vibrations from the frame to the wall.
  • the air tightness and therefore the acoustic insulation of the wall are also reinforced by the installation, on the wing 6 of the plate 1 or 36 of the plate 31, of a flexible adhesive seal. This joint is pinched during installation between the various plates which fit together successively.
  • the per Formations obtained are close to those of a concrete veil of several hundred kg / m 2 .
