Definitions

  • the invention relates to a sound-absorbing element for the construction of a seamless acoustic ceiling consisting of a perforated plate, which is covered on the room side on a non-woven layer covering the perforations with a sound-permeable plaster layer and is deposited on the side facing away from the room with a soundproofing layer, which is assigned an impermeable cover film.
  • the cover film thus prevents the locations of the perforations behind it, which are covered by the plaster layer itself, from standing out clearly over time.
  • the arrangement of the impermeable cover film directly on the perforated plate ensures that the ceiling is no longer unsightly, but leads to a noticeable impairment of the sound absorption value, and the frequency range of the sound absorbed by the ceiling element is limited. Since in the known design the sound insulation layer of the sound absorbing ceiling element is delivered separately to the construction site and is applied as a separate layer on the side of the perforated plate facing away from the room when the acoustic ceiling is installed, this method of installation often leads to inaccurate laying of the sound insulation layer, especially since its extension is above cannot see the perforated plate after completion of the suspended acoustic ceiling. As a result, such a ceiling element leaves something to be desired in terms of sound absorption properties.
  • the invention has for its object to further develop the ceiling element of the type mentioned that not only the pollution of the plaster layer due to the filter effect in the area of the holes in the perforated plate is avoided, but also the correct arrangement of the insulation layer is inevitably ensured, namely on economically particularly favorable way, which also ensures a high broadband of the Absorptionsvenn ⁇ Q ens.
  • the sound absorbing ceiling element according to the invention in which this object is achieved, is essentially characterized in that the soundproofing layer is covered on its side facing away from the perforated plate with the impermeable cover film.
  • the individual layers namely the perforated panel with fleece layer and plaster layer on one side and with soundproofing layer and impermeable cover film on the other side, are combined from the outset.
  • the correct arrangement of the parts on top of one another is thus necessarily ensured by the prefabrication. Since the impermeable cover film is now no longer arranged above the perforated plate in the sound-absorbing ceiling element, but rather below the soundproofing layer but rather on the soundproofing layer, which in turn lies on the perforated plate, surprisingly a better absorption capacity has been shown, namely an increased broadband over a larger frequency range.
  • the sound-absorbing ceiling element as a structural unit, which inevitably also includes the soundproofing layer, there is greater economic efficiency, since the entire unit can be manufactured and delivered to the construction site in a factory-made manner. Accordingly, it can be manufactured in both summer and winter regardless of the weather. Since the individual parts of the ceiling elements do not have to be put together on the building, errors being inevitable, the ceiling element according to the invention leads to better quality results despite shorter assembly times on the building.
  • the displacement of the impermeable cover film from the area above the perforated plate and below the soundproofing layer to the top of this soundproofing layer has not brought with it the disadvantage that one could have expected, according to which the larger air volume of the holes in the perforated plate and in the area through the Sound insulation layer through to the cover film entails a correspondingly larger air movement when sound hits, which in turn results in a deposit of dirt particles in the area of the lower cover of the holes in the perforated plate through the applied plaster layer.
  • the plaster layer remains clean on the plaster areas in front of the holes in the perforated plate.
  • the soundproofing layer is an art Assigned fabric or metal foil cover and by creating overlaps of the film edges ensures that sound can not bypass the side edges of the cover film and emerge upwards and reach the space above.
  • the object of the invention in which this problem does not arise at all, is much more about creating an economically producible, seamless acoustic ceiling with the widest possible absorption spectrum.
  • the underside of the known ceiling element comprises a perforated plate which remains uncovered, ie also in the area of the plate edges without an applied plaster layer. The plate structure can thus be recognized even after the ceiling has been completed.
  • a ceiling suspension is attached with the upper end (not shown in the figure) to the ceiling of the room to be provided with the suspended acoustic ceiling.
  • the basic profile 14 of the ceiling suspension is fastened to the ceiling suspension 10 via anchor elements 12. This basic profile extends over the entire ceiling and permits in a known manner, the hanging of the actual ceiling elements via anchor angles 16, which can be hooked in across the base profile 14 with their angle at the top and are connected below by means of fastening elements 18, which are only symbolically indicated in the figure, to the ceiling elements 20 constructed as a sandwich panel.
  • the ceiling element 20 consists of a larger number of layers.
  • the supporting element is a perforated plate 22 made of plasterboard.
  • the perforations are regularly drawn in the figure. They can also have a regular distribution. However, it has been shown in practice that the provision of perforations of different sizes in the perforated plate further improves the acoustic properties.
  • the thickness of the perforated plasterboard can preferably be between 10 and 15 mm.
  • the perforated plate 22 is covered on its lower, surface-side surface with a non-woven layer 24, preferably made of glass fibers, which overlaps the perforations and thus again forms a closed surface.
  • the ceiling element 20 carries a thin, sound-permeable, optically but impermeable and rigid plaster layer 26.
  • the plaster layer 26 is preferably closed or pulled through in the area of the butt joints between adjacent ceiling elements 20, so that a closed plaster layer arises that no longer reveals the character of the ceiling it covers.
  • the sandwich panel forming the ceiling element 20 has a sound insulation layer 28.
  • This lies directly on the back of the perforated plate 22, but has a considerably greater thickness than this, which should be at least twice the thickness of the perforated plate 22 in order to ensure the effectiveness of the sound-absorbing properties of the acoustic ceiling.
  • the soundproofing layer 28 can also be constructed from glass fibers or rock wool.
  • the sandwich panel forming the ceiling element 20 is covered on its side facing away from the room as the last layer by a cover film 30 which prevents air circulation from entering through the sandwich panel.
  • the sound-absorbing property of the ceiling element is thus not adversely affected.
  • the unpleasant contamination of the face side of the ceiling element 20 is, however, effectively prevented.
