Abstract

An acoustic panel for use in building comprises a perforated carrier plate and noise-absorbing materials. The carrier plate has perforations distributed over at least 5% of the surface area, these perforations being (partly) filled with open-cell plastics foam. The carrier plate may be mace of transparent plastics. In contrast to prior-art similar prods the acoustic panels as claimed may be made either transparent or translucent, as desired. Owing to their compositions and constructions they are not thermally insulating and so present no problems from a heat- and diffusion-technological point of view.

Description

Akustikplatte und Verfahren zur Herstellung Die Erfindung betrifft eine Akustikplatte, bestehend aus einer gelochten Tragerplatte und Schallschluckstoffen und ein Verfahren zur Herstellung dieser Akustikplatte. Acoustic Panel and Method of Manufacture The invention relates to an acoustic panel, consisting of a perforated support panel and sound-absorbing materials and a method for manufacturing this acoustic panel.

Im allgemeinen bestehen Akustikplatten aus faserigem oder offenzelligem Material von poröser Struktur. Dadurch sind derartige Platten weder durchsichtig noch durchscheinend.In general, acoustic panels are made of fibrous or open-celled Material with a porous structure. As a result, such plates are neither transparent still translucent.

Des weiteren haben sie aufgrund ihres Aufbaues eine verhältnismäßig hohe Wärmedämmung, was bei bestimmten Bauwerkskonstruktionen wsrme- und diffusionstechnische Schwierigkeiten mit sich bringt.Furthermore, due to their structure, they have a proportionate high thermal insulation, which in certain building constructions has thermal and diffusion technology Brings difficulties.

Derartige Akustikplatten können mit einer Abdeckung aus Metall, Kunststoff, Holz, Gips oder dergleichen versehen sein, wobei diese Abdeckungen erfahrungsgemäß die Absorption nicht mindern, wenn sie durcnbrochen sind mit einem offenen Querschnitt von mindestens etwa 20 %. Dadurch dringt der einfallende Schall nahezu ungehindert durch diese Durchbrechungen hindurch in das dahinterliegende, schallabsorbierende, poröse Material.Such acoustic panels can be covered with a cover made of metal, plastic, Wood, plaster of paris or the like can be provided, with these covers being experience has shown do not reduce absorption if they are perforated with an open cross-section of at least about 20%. As a result, the incident sound penetrates almost unhindered through these openings into the sound-absorbing, porous material.

Der Erfindung liegt die Aufgabe zugrunde, eine Akustikplatte zu schaffen, die keine taupunktverlagernde Wärmedämmung darstellt und bei Bedarf durchsichtig bzw. durchscheinend ist.The invention is based on the object of creating an acoustic panel, which does not represent a dew point shifting thermal insulation and if necessary transparent or is translucent.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Trägerplatte der Akustikplatte - vorzugsweise transparenter Kunststoff - mindestens 5 % über ihre Fläche verteilte Durchbrechungen aufweist, wobei diese Durchbrechungen teilweise oder vollständig durch offenzelligen Kunststoff ausgefüllt sind.According to the invention this object is achieved in that the carrier plate the acoustic panel - preferably transparent plastic - at least 5% above their area has distributed perforations, these perforations partially or are completely filled with open-cell plastic.

Weiterhin können als Trägerplatte Wabensteine aus Ton oder Beton bzw. Metallplatten eingesetzt werden. Durch die hohe Wärmeleitfähigkeit dieser Materialien erfolgt beim Einsatz der vorgeschlagenen Akustikplatten bei Wand- oder Deckenkonstruktionen keine Taupunktverlagerung. Als schallabsorbierender Kunststoff zum Ausfüllen der Durchbrechungen der Akustikplatte wird hauptsächlich Polyurethan, Polycarbonit, PVC oder dergleichen verwendet, wobei die besten Ergebnisse mit Polyurethan zu erreichen sind.Furthermore, honeycomb stones made of clay or concrete or Metal plates are used. Due to the high thermal conductivity of these materials occurs when the proposed acoustic panels are used in wall or ceiling constructions no dew point shift. As a sound-absorbing plastic to fill in the Breakthroughs in the acoustic panel are mainly made of polyurethane, polycarbonite, PVC or the like is used, with polyurethane for best results are.

Infolge des vergrößerten akustischen Einzugsgebietes verteilter oeffnungen kann bei optimalem akustischen Widerstand des Absorptionsmaterials in den Durchbrechungen ein sehr hoher Schallschluckgrad erreicht werden. Der günstigste Bereich für den akustischen Strömungswiderstand der Gesamtanordnung beträgt 20 - 2000 Rayl.As a result of the enlarged acoustic catchment area, distributed openings can with optimal acoustic resistance of the absorption material in the openings a very high degree of sound absorption can be achieved. The cheapest area for the acoustic flow resistance of the entire arrangement is 20 - 2000 Rayl.

Um neben den schalldämpfenden Eigenschaften der erfindungsgemäßen Platte eine ausreichende Schalldämmung zu erreichen, weist die der Schallquelle abgewandte Seite der Platte Abdekkungen aus Kunststoff, Metall, Holzwerkstoff, Putz oder dergleichen auf.In addition to the sound-absorbing properties of the invention To achieve sufficient sound insulation, the plate has to do with the sound source remote side of the plate covers made of plastic, metal, wood-based material, plaster or the like.

Die Herstellung der erfindungsgemäßen Akustikplatten geschieht dadurch, daß mehrere Trägerplatten aufeinandergelegt und die Durchbrechungen mit dem offenzelligen Kunststoff ausgeschäumt werden. Nach dem Ausschäumen werden die Aufschäumungen mechanisch getrennt, wobei diese Trennung durch vor dem Aufschäumen -zwischen die jeweiligen Trägerplatten ebenfalls deckungsgleich eingelegte-Trennmaterialièn, wie Papier-, Schaumkunststoffs Faservlies, Folien oder dergleichen erleichtert werden.The acoustic panels according to the invention are produced by that several carrier plates are placed on top of one another and the openings with the open-cell Plastic can be foamed. After the foaming, the foaming becomes mechanical separated, this separation by before foaming -between the respective Carrier plates also congruently inserted separating materials, such as paper, Foam plastic Fiber fleece, foils or the like facilitated will.

Weitere Einzelheiten der Erfindung sind aus der Zeichnung und der folgenden Beschreibung zu entnehmen.Further details of the invention are from the drawing and the can be found in the following description.

Die erfindungsgemäße Akustikplatte besteht aus einer Trägerplatte (1), die vorzugsweise aus transparentem Material, wie z.B. Acrylglas oder PVC, sein kann und dem schallabsorbierenden, offenzelligen Kunststoff (5), der die Durchbrechungen (2) ganz oder teilweise ausfüllt. Anstelle der kreisförmigen Öffnungen können auch Schlitze oder anders geformte, beliebige Durchbrechungen vorgesehen sein.The acoustic panel according to the invention consists of a carrier panel (1), which should preferably be made of transparent material such as acrylic glass or PVC can and the sound-absorbing, open-cell plastic (5), which the openings (2) completely or partially filled out. Instead of the circular openings can also Slits or any other shaped perforations can be provided.

Um die erfindungsgemäße Akustikplatte auch für Schalldämmmaßnahmen einsetzen zu können, weist die Platte auf der der Schallquelle abgewandten Seite eine Abdeckung (4) aus z.B.To the acoustic panel according to the invention also for sound insulation measures to be able to use, has the plate on the side facing away from the sound source a cover (4) made of e.g.

Metall auf.Metal on.
