Abstract

Plate-like sound-insulation element for rooms, especially offices, has a corrugated surface (1) facing the inside of the room. Preferred Features: The corrugated surface is grooved. The grooves (2) form an angular pattern, preferably a square pattern. The depth of the grooves is the same as the height of the corrugated surface. The sound-insulation element is made of a melamine resin foam. The sound-refracting elements are arranged in the grooves.

Description

Die Erfindung betrifft ein plattenartiges Schallschutzbauelement für Gebäuderäume, insbesondere Arbeitsräume.The invention relates to a plate-like soundproofing component for building rooms, especially work rooms.

In Gebäuderäumen, insbesondere Arbeitsräumen, müssen Schallschutzmaßnahmen getroffen werden, um die durch den entstehenden Schallpegel verursachte Belastung der im Raum befindlichen oder arbeitenden Personen herab zu setzen. In building rooms, especially work rooms, must Soundproofing measures are taken to avoid those arising from the Sound level caused a load on those in the room or to lower working people.

Durch die Erfindung soll ein Schallschutzbauelement geschaffen werden, das vielseitig in Räumen mit hohem Schallpegel wie beispielsweise in Unterrichtsräumen, Fluren, Aulen usw. eingesetzt werden kann und nachträglich eingebaut werden kann.The invention is intended to create a soundproofing component be versatile in rooms with high sound levels such as in classrooms, corridors, auditoriums etc. can be used and installed later can.

Dazu ist das erfindungsgemäße plattenartige Schallschutzbauelemente dadurch gekennzeichnet, daß die der Rauminnenseite zugewandte Fläche gewellt ist.For this purpose, the plate-like soundproofing components according to the invention characterized in that the inside of the room facing surface is corrugated.

Besonders bevorzugte Weiterbildungen und Ausgestaltungen sind Gegenstand der Patentansprüche 2 bis 7.Particularly preferred further developments and refinements are the subject of claims 2 to 7.

Im folgenden wird anhand der zugehörigen Zeichnung ein besonders bevorzugtes Ausführungsbeispiel des erfindungsgemäßen Schallschutzbauelementes näher beschrieben. Es zeigen

  • Fig. 1 verschiedene Seitenansichten des erfindungsgemäßen Schallschutzbauelementes sowie eine Seitenansicht eines aus diesen Elementen zusammengesetzten Schallschutzfeldes und
  • Fig. 2 eine Draufsicht auf die der Rauminnenseite zugewandte Fläche eines aus mehreren erfindungsgemäßen Schallschutzbauelementen zusammengesetzten Schallschutzfeldes.
    • A particularly preferred exemplary embodiment of the soundproofing component according to the invention is described in more detail below with reference to the accompanying drawing. Show it
  • Fig. 1 shows various side views of the soundproofing component according to the invention and a side view of a soundproofing field composed of these elements and
  • Fig. 2 is a plan view of the surface facing the interior of a soundproofing field composed of several soundproofing components according to the invention.

    • Wie es in Fig. 1 dargestellt ist, hat das erfindungsgemäße Schallschutzbauelement die Form einer Platte, deren Außenfläche, die im montierten Zustand des Schallschutzbauelementes der Rauminnenseite zugewandt ist, mit Wellungen versehen ist.As shown in Fig. 1, the inventive Soundproofing component in the form of a plate, the outer surface of which those in the assembled state of the soundproofing component facing the inside of the room is provided with corrugations.

    Das Schallschutzelement kann an einer Raumdecke aber auch an Raumwänden angebracht oder im Inneren eines Raumes aufgehängt bzw. von der Decke abgehängt angeordnet sein. Es kann insbesondere mit einem Kleber oder Tapetenkleister aber auch über eine Schraubbefestigung angebracht werden.The soundproofing element can also on a ceiling attached to room walls or hung inside a room or be suspended from the ceiling. It can but especially with an adhesive or wallpaper paste can be attached via a screw fastening.

    Wie es weiterhin in Fig. 1 dargestellt ist, sind in der gewellten Fläche 1 des Schallschutzbauelementes Nuten 2 vorgesehen, die insbesondere eine Tiefe haben, die gleich der Wellenhöhe der gewellten Fläche 1 ist.As further shown in Fig. 1, are in the corrugated surface 1 of the soundproofing component grooves 2 are provided, which in particular have a depth equal to the wave height the corrugated surface is 1.

    Wie es in Fig. 2 dargestellt ist, verlaufen diese Nuten 2 über die gesamte Fläche des Schallschutzbauelementes derart, daß sie einander schneiden und ein Winkelmuster bilden. Bei dem in Fig. 2 dargestellten Ausführungsbeispiel sind die Nuten 2 so angeordnet und ausgebildet, daß sie ein rechtwinkliges Muster oder Karomuster bilden. Das Muster kann auch rautenartig oder in anderer Weise ausgebildet sein.As shown in FIG. 2, these grooves 2 run over the entire area of the soundproofing component in such a way that they intersect and form an angle pattern. at the embodiment shown in Fig. 2 are the grooves 2 arranged and designed so that they are rectangular Form a pattern or check pattern. The pattern can also be diamond-like or be formed in some other way.

    Das oben beschriebene Schallschutzbauelement besteht vorzugsweise aus einem Kunstharz, insbesondere aus einem Melaminharz-Schaum nach DIN 4102 B1 in der schwer entflammbaren Variante.The soundproofing component described above is preferably made from a synthetic resin, in particular from a melamine resin foam according to DIN 4102 B1 in the flame retardant version.

    Wie es in Fig. 1 und Fig. 2 dargestellt ist, können die einzelnen Schallschutzbauelemente zu größeren flächigen Gebilden zusammengesetzt werden derart, daß z.B. die gesamte Raumdecke überdeckt ist. Aufgrund dieses modularen Aufbaus ist auch ein nachträglicher Einbau in bestehenden Gebäude möglich und kann die Montage an jede Gebäudeform, Raumform oder Dekkenform angepaßt werden.As shown in Fig. 1 and Fig. 2, the individual soundproofing components to form larger flat structures are assembled such that e.g. the entire ceiling is covered. Because of this modular structure Subsequent installation in existing buildings is also possible and can be fitted to any building shape, room shape or ceiling shape be adjusted.

    Dadurch, daß die dem Rauminneren zugewandte Fläche des Schallschutzbauelementes gewellt ist, wird eine relativ große Oberfläche erzielt, die den auftretenden Schall sehr gut bricht und dadurch eine Schalldämmung herwirkt.The fact that the surface facing the interior of the Soundproofing component is corrugated, becomes a relatively large Surface achieved that the sound occurring very well breaks and thereby creates sound insulation.

    Die in die gewellte Fläche geschnittenen Nuten 2 lassen es darüber hinaus zu, beispielsweise an einer Decke befestigte Bauelemente wie Fernsehhalterungen oder abgependelte Deckenleuchten auszusparen, wobei in die Nuten 2 auch weitere schallbrechende Elemente eingeschoben sein können, die den Schallschutz verstärken.The grooves 2 cut into the corrugated surface leave it in addition, for example, attached to a ceiling Components such as TV brackets or suspended ceiling lights to be left out, in the grooves 2 also more sound-breaking elements can be inserted that the Reinforce sound insulation.
