Abstract
Description
Die Erfindung bezieht sich auf eine schallabsorbierende Akustikplatte mit profilierter Oberfläche und Durchbrechungen.The invention relates to a sound-absorbing acoustic panel with a profiled Surface and perforations.
Die schallabsorbierende Wirkung von Oberflächenprofilierungen und Hohlräumen von Lärmschutzeinrichtungen, z.B. Akustikplatten, ist bekannt. So ist bereits eine mit profilierter Oberfläche und mit Durchbrüchen versehene schallabsorbierende Platte bekannt geworden, die aus einer Dreischicht-Massivholzplatte durch spanabhebende Schlitzungen hergestellt wird. Dieses Verfahren ist aufwendig. Außerdem sind Holzwerkstoffe für Anwendungen im Freien vielfach nicht ausreichend dauerhaft.The sound absorbing effect of surface profiles and cavities of Noise protection devices, e.g. Acoustic panels, is known. So is already one with profiled Surface and perforated sound-absorbing plate known become that from a three-layer solid wood panel by cutting Slits is made. This process is complex. In addition, wood materials often not sufficiently durable for outdoor applications.

Dies wird erfindungsgemäß durch mindestens zwei übereinander liegende und miteinander verbundene, sich kreuzende Scharen von Stäben aus einem ausgehärteten Formstoff erreicht, wobei die Stäbe einer Schar zwischen sich durchlaßbildende Abstände bilden.According to the invention, this is achieved by at least two superimposed ones and one another connected, intersecting sets of rods from a hardened Molded material reached, the rods of a coulter between them forming passage Form distances.
Die Kreuzung der Stäbe erfolgt vorzugsweise unter einem Winkel von 90°.The bars are preferably crossed at an angle of 90 °.
Gemäß einer bevorzugten Ausführungsform besteht die schallabsorbierende Akustikplatte aus drei übereinander liegende und miteinander verbundene Scharen von Stäben, wobei sich die Stäbe der mittleren Lage sowohl mit den Stäben der darüberliegenden Lage als auch mit den Stäben der darunter liegenden Lage von Stäben kreuzen.According to a preferred embodiment, the sound-absorbing acoustic panel is made from three superimposed and interconnected groups of Rods, with the rods of the middle layer both with the rods of the one above Location as well as with the bars of the underlying layer of bars cross.
Aus herstellungstechnischen Gründen und auch zur Erzielung eines guten Verbundes ist es zweckmäßig, wenn die Stäbe einer Lage mit den Stäben der anderen Lage stoffschlüssig miteinander verbunden sind, was etwa dann der Fall ist, wenn die aus Lagen sich kreuzender Stäbe bestehende Akustikplatte einstückig hergestellt wird. Es wäre aber auch möglich, die zunächst einzelnen Stäbe herzustellen und diese dann kreuzweise miteinander zu verbinden, z.B. zu verkleben. For manufacturing reasons and also to achieve a good bond it is expedient if the rods of one layer are integral with the rods of the other layer are connected to each other, which is the case when the layers Acoustic panel consisting of crossing bars is produced in one piece. It would be but it is also possible to produce the individual rods first and then cross them connect with each other, e.g. to glue.
Der Begriff "ausgehärteter Formstoff" umfaßt Werkstoffe, die aus formbaren Formmassen durch spanlose Formung (in Formen) hergestellt werden, und zwar solche mit anorganischen Bindemitteln wie Zement oder Gips, als auch solche mit organischen Bindemitteln wie Kunststoffe bzw. Kunstharze. Die Formstoffe können Zuschlagstoffe, Verstärkungseinlagen und Füllstoffe enthalten. Ein Beispiel mit besonderen Verarbeitungs- und Gebrauchseigenschaften ist Polymerbeton (Kunstharzbeton).The term "hardened molding material" includes materials that are made from moldable molding materials be produced by chipless shaping (in molds), namely with inorganic binders such as cement or gypsum, as well as those with organic Binders such as plastics or synthetic resins. The molding materials can be aggregates, Reinforcements and fillers included. An example with special processing and usage properties is polymer concrete (synthetic resin concrete).

Die gitterförmige Akustikplatte nach Fig. 1 bis 3 besteht einstückig gefertigt aus drei
Lagen von sich kreuzenden Scharen von Stäben 1,2,3, z.B. aus Polymerbeton. Die
Stäbe 1,3 der äußeren Lagen weisen trapezförmigen Querschnitt auf. Die Stabhöhe
beträgt z.B. 10 bis 12 mm, die Stabbreite z.B. 10 bis 18 mm und der Stababstand z.B.

Stahlformen oder auch Formen aus anderem Material erfolgen:The manufacture of this grid-shaped acoustic panel can preferably be done in the following in three ways, e.g. Steel molds or too Shapes made from other material:
Eine erste, z.B. wannenförmige Form weist rinnenförmige Formvertiefungen für die
Stäbe 1 der unteren Lage auf. Die Formvertiefungen (Formhohlräume) werden mit der
aushärtbaren Formmasse, z.B. einer Polymerbetonmischung, gefüllt und glattgestrichen.
Sodann wird eine zweite, vorzugsweise kammartige Form mit fingerartigen
Formelementen mit nach oben und unten offenen länglichen Formhohlräumen für die
Stäbe 2 der mittleren Lage aufgesetzt, und es werden wiederum die Formhohlräume
mit der aushärtbaren Formmasse gefüllt. Schließlich wird eine dritte Form aufgesetzt,
ähnlich jener wie die erste Form, mit länglichen Formhohlräumen für die obere Lage
der Stäbe 3, wobei aber bei der dritten Form die Formhohlräume zum Einfüllen der
aushärtbaren Formmasse nach oben offen sind. Nach dem Aushärten der Formmasse,
z.B. der Polymerbetonmischung, wird entschalt, indem zuerst die dritte Form
abgehoben und dann die zweite Form seitlich herausgezogen wird. Schließlich wird die
fertige gitterförmige Platte aus der ersten Form ausgehoben oder durch Wenden der
ersten Form herausgestürzt. Die kammartige zweite Form kann zur leichteren seitlichen
Entnahme nach dem Abbinden der Formmasse zweiteilig ausgebildet sein, so
daß je eine halbe zweite Form nach zwei entgegengesetzten Richtungen seitlich
herausgezogen werden kann. Außerdem ist es zur leichteren Entschalung zweckmäßig,
wenn die Stäbe 2 der mittleren Lage und die entsprechenden Formhohlräume
zu ihren seitlichen Längsenden hin leicht konisch ausgebildet sind. Auch der
trapezförmige Querschnitt der Stäbe 1 und 3 der unteren und oberen Lage dient zum
leichteren Entformen. Statt Stäben mit trapezörmigem Querschnitt wären aber auch
andere Stabformen mit sich nach außen (oben bzw. unten) verjüngenden Seitenflächen
möglich, z.B. Stäbe mit dreieckigem oder halbkreisförmigem Querschnitt.A first, e.g. trough-shaped form has groove-shaped recesses for the
