Definitions

  • the present invention relates to a sound-insulating panel consisting of a supporting plate with a layer of insulating material disposed thereon, said layer of insulating material being enclosed by a peripheral rigid frame which is arranged along the perimeter of and connected to the supporting plate.
  • a sound-insulating panel of this type is known from Dutch patent application 78.03674.
  • This prior art panel is attached to a wall such that the frame contacts such wall. Therefore a serious drawback of this panel is that the frame acts as a good sound conductor between the plate of the panel and said wall.
  • An object of the invention is to solve said prior art drawback.
  • a panel of the type mentioned in the introduction according to the invention that a strip of insulating material having a higher compressibility than the frame is disposed on the frame, the overall height of the edge structure formed by the frame and the strip being approximately equal to the thickness of the layer of insulating material. Since said strip has a higher compressibility than said frame it forms a resistance for sound conduction between the plate and a wall where other construction components against which the panel is attached, while the rigidity of the panel is maintained.
  • the sound insulating panel is such that the edge structure comprises a further frame arranged on the strip of insulating material, that a further plate is arranged on said further frame, such that the insulating layer is enclosed by bothplates and both frames with the strip of insulating material therebetween, that the frames are made of wood and that the height of one frame is twice the height of the other frame.
  • the edge structure comprises a further frame arranged on the strip of insulating material, that a further plate is arranged on said further frame, such that the insulating layer is enclosed by bothplates and both frames with the strip of insulating material therebetween, that the frames are made of wood and that the height of one frame is twice the height of the other frame.
  • a prefabricated wall panel consisting of two symmetrical flat parts each having a metal plate having a frame of plastic foam along the periphery thereof, which parts are arranged against each other with the frames opposing each other and enclosing an insulating layer between both plates and the edge structure.
  • the opposing faces of both frames have a recess for receiving therein a thin strip of soft foam having an adhesive on both main surfaces for connecting both panel parts to said strip on a slight distance from each other.
  • the frames being made of plastic foam and the small height of the strip between both frames the sound insulating characteristics, in particular for low audio frequencies is rather poor.
  • the plastic foam frames do not contribute substantially to the rigidity of the panel and are not suitable to be used for attachment of the panel to some construction, for instance by nails or screws.
  • a sound-insulating panel 1 consists of a supporting plate 2, along the perimeter of which there is disposed a peripheral wooden frame 3.
  • a strip of insulating material 4 is disposed on said peripheral frame 3.
  • a layer of insulating material 5 whose thickness is virtually equal to the sum of the height of the frame 3 and the strip of insulating material 4.
  • the height of the strip of insulating material 4 is appreciably less than that of the frame 3.
  • the strip of insulating material 4 may have a lower compressibility than the layer of insulating material 5 so that the pressure loadings are mainly absorbed by the edge structure of the components.
  • Figure 2 shows that the peripheral frame 3 to some extent projects outside the supporting plate so that, if several panels 1 are placed next to each other, grooves are produced between the supporting plates of the panels adjacent to each other in which mounting laths can be disposed as will also be described below.
  • Figure 3 shows another embodiment of the sound-insulating panel in which a second rigid peripheral frame 6 is disposed on the strip of insulating material 4, on which frame a second supporting plate 7 is mounted.
  • the height of the second frame 6 is appreciably less than that of the first frame. In the embodiment shown this height approximately corresponds to that of the strip of insulating material 4.
  • This type of panel is suitable, in particular, for sloping roofs and can be mounted directly on the purlins. Since there is no direct contact between the supporting plates 2 and 7, a particularly good sound insulation is ensured, while the panel has an adequate strength and rigidity as a result of the wooden frames 3 and 6.
  • the insulation material used is formed by an opencell elastic polyurethane foam which consists of selected original polyurethanes of varying density from which, after flaking and adding additional substances and a binding agent, blocks are made. These are sawn into panels of the desired thickness Depending on the desired density, the flakes are to a greater or lesser extent compressed into blocks whose density varies from 80 to 240 kg/m3.
  • the supporting plates consist preferably of a cement-bonded fibre plate, plasterboard, fibre-bonded plaster plate, waterproof plywoord and the like.
  • the panels constructed with a single supporting plate 2 from the Figures 1 and 2 are intended, in particular, for lining existing roofs, sidewalls or floors, the strip of insulating material 4 preventing any contact sound between the structure and the supporting plate, and the panels nevertheless having an adequate strength and rigidity.
  • Figure 4 shows a roof structure in section which is made up of a number of panels of the type shown in Figure 3 which adjoin each other.
  • the supporting plate 2 to some extent projects at one side and overlaps the frame 3 of the next element adjoining thereto, as a result of which a good joining of the panels situated adjacent to each other is obtained.
  • the supporting plates 7 of two panels adjacent to each other are at some distance from each other so that a mounting lath or batten 8 can be disposed in between.
  • Figure 5 shows a section of a roof which is insulated by means of the panels shown in Figures 1 and 2.
  • the figure shows a purlin 11 with a roof boarding 12 on which the panels are disposed, the side edges of which panels are adjacent to each other.
  • Figure 6 shows graphically the atmospheric noise insulation of the structure in Figure 5. From this graph it is clearly evident that the sound insulation in the high frequency range is much higher that the standard values laid down in NEN 1070.
  • a good sound insulation can be obtained by lining existing roofs, walls or floors with the panels shown in Figures 1 and 2 and also that good sound-insulating walls can be constructed by means of the panels of the type shown in Figure 3.
  • the panels may possibly be provided with suitable decorative coverings without the quality of the sound insulation thereby being reduced.
  • the invention is not limited to the embodiments shown in the drawing, but that a large number of modifications is possible within the scope of the invention.
  • a further thin layer of insulating material with a low compressibility can be provided in the case of the component shown in Figure 1, which layer covers both the edge strip and the layer of insulating material situated inside it.
  • This embodiment provides, in particular, a good sound insulation in the lower frequency range.
