This is followed in turn by an intermediate sound-permeable layer, preferably of fibrous material, and a sound-absorbent layer, preferably of mineral wool. On the side of the grille (4) furthest from the metal plate (2) is a stiffening plate (5) with apertures (52) and glued to it. The grille is formed by undulating strips (42,42',42") of thin sheet material glued together. USE/ADVANTAGE - Economy of material combined with good sound-absorption and high resistance to bending.

Description

Die Erfindung betrifft eine Abdeckplatte für den Einsatz als Decken- oder Wandverkleidung mit einer mit Durchbrüchen ver­ sehenen metallischen Sichtplatte, mit einem hinter der Sicht­ platte angeordneten, durch eine Klebeverbindung mit der Sicht­ platte verbundenen und mit den Durchbrüchen in der Sichtplatte kommunizierende Kanäle bildenden Wabengitter vorzugsweise aus Aluminium, einer hinter dem Wabengitter angeordneten, beispielsweise aus Mineralwolle bestehenden Schallabsorptions­ schicht und einer vorzugsweise aus einem Faservlies bestehen­ den schalldurchlässigen Zwischenschicht.The invention relates to a cover plate for use as Ceiling or wall cladding with a ver see metallic faceplate, with a behind the sight plate arranged, with an adhesive connection with the view plate connected and with the openings in the faceplate honeycomb grid forming communicating channels preferably made of aluminum, one arranged behind the honeycomb grid, for example, sound absorption made of mineral wool layer and one preferably consist of a nonwoven fabric the sound-permeable intermediate layer.

Derartige Abdeckplatten werden zur Schalldämmung eingesetzt und dienen gleichzeitig als Sichtverblendung von Decken oder Wänden. Sie müssen zur Verminderung der Brandgefahr aus einem nichtbrennbaren oder schwer entflammbaren Material bestehen.Such cover plates are used for sound insulation and also serve as a veneer for ceilings or Walls. You need to reduce the risk of fire from one non-flammable or flame-retardant material.

Eine bekannte Abdeckplatte dieser Art (DE-GM 73 38 148) weist eine als Metalldrahtgewebe oder als Metallgitter ausgebildete Sichtplatte, sowie ein Wabengitter aus Aluminium auf, das in einen die Sichtplatte tragenden Rahmen eingelegt und zur Stabilisierung der Sichtplatte mit deren Rückseite verklebt ist. Dadurch wird auch bei großflächigen Deckenplatten ein Durchhang der Sichtplatte verhindert. Das Wabengitter ist dort als solches selbsttragend und formstabil ausgebildet und daher relativ materialaufwendig und schwer.A known cover plate of this type (DE-GM 73 38 148) has one designed as a metal wire mesh or as a metal grid Faceplate, as well as an aluminum honeycomb grille on the placed in a frame supporting the faceplate and for Stabilization of the faceplate glued to the back is. This means that even with large-surface ceiling tiles Sag of the faceplate prevented. The honeycomb grid is trained as such self-supporting and dimensionally stable and therefore relatively expensive and heavy.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Abdeckplatte der eingangs angegebenen Art zu entwickeln, die trotz geringem Materialeinsatz eine hohe Biegesteifigkeit sowie gute schalldämmende Eigenschaften in sich vereint.Proceeding from this, the invention is based on the object to develop a cover plate of the type specified at the outset, which, despite the low use of materials, has a high level of flexural rigidity as well as good sound-insulating properties combined.

Zur Lösung dieser Aufgabe werden erfindungsgemäß die im Kenn­ zeichenteil des Patentanspruchs 1 angegebenen Merkmale vorge­ schlagen.

Gemäß einer bevorzugten Ausgestaltung der Erfindung besteht das Wabengitter aus einer Vielzahl rippen-, zickzack- oder wellenförmig gebogener, unter Bildung waben- oder rautenförmi­ ger Öffnungen auf ihren Breitseiten abschnittsweise miteinan­ der verklebter dünner Folienstreifen, deren einander gegenüber­ liegende Längskanten mittels einer Klebeverbindung mit der durchbrochenen Sichtplatte sowie mit einer der Sichtplatte gegenüberliegenden, ebenfalls durchbrochenen Versteifungsplatte verbunden sind.According to a preferred embodiment of the invention the honeycomb grid from a variety of ribbed, zigzag or wavy curved, forming honeycomb or diamond-shaped openings on their broad sides in sections the glued thin film strips, their opposite each other lying longitudinal edges by means of an adhesive connection with the openwork faceplate as well as with one of the faceplate opposite, also openwork stiffening plate are connected.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist zwischen der Sichtplatte und dem Wabengitter eine vorzugs­ weise aus einem dünnen Faservlies bestehende schalldurchlässige Zwischenschicht angeordnet, die auf ihrer einen Breitseite mit der Rückseite der Sichtplatte und auf ihrer anderen Breit­ seite mit dem Wabengitter mittels eines Klebstoffs verbunden ist. Diese gleichzeitig als Rieselschutz und als Sichtver­ kleidung des Wabengitters dienende Zwischenschicht kann auf ihrer der Sichtplatte zugewandten Breitseite mit Metall, vor­ zugsweise Aluminium bedampft sein.According to a further preferred embodiment of the invention is a preference between the faceplate and the honeycomb grid wise consisting of a thin fiber fleece sound-permeable Intermediate layer arranged on one broadside  with the back of the faceplate and on its other width side connected to the honeycomb grid by means of an adhesive is. This at the same time as trickle protection and as visual protection The intermediate layer serving the honeycomb grid can its broad side facing the faceplate with metal preferably be steamed with aluminum.

Nach einer vorteilhaften Ausgestaltung der Erfindung ist sowohl die Sichtplatte als auch die Versteifungsplatte als dünnwandige Aluminiumplatte mit ausgestanzten Durchbrüchen ausgebildet. Zur Befestigung der Abdeckplatte kann die Sichtplatte mit rechtwinklig nach hinten umgebogenen, die rückwärtige Verstei­ fungsplatte wannenartig übergreifenden Rändern versehen sein. Die Ränder der Abdeckplatte weisen zweckmäßig Bohrungen, Schlitze oder umlaufende Nuten zum Einhängen von Halte- oder Abhängevorrichtungen und/oder zum Anbringen von Verbindungs­ elementen beim Aneinanderfügen mehrerer Abdeckplatten auf.According to an advantageous embodiment of the invention, both the face plate and the stiffening plate as thin-walled Aluminum plate with punched openings. To attach the cover plate, the face plate can be used bent backwards at right angles, the rear reinforcement tion plate overlapping trough-like edges. The edges of the cover plate expediently have holes, Slots or circumferential grooves for hanging holding or Suspension devices and / or for attaching connections elements when joining several cover plates.

Die Schallabsorptionsschicht kann auf die Rückseite der Ver­ steifungsplatte aufgeklebt sein oder durch eine Deckfolie gehalten werden, die mit den nach hinten umgebogenen Rändern der Sichtplatte verbindbar ist.The sound absorption layer can on the back of the Ver stiffening plate glued or through a cover film are held with the edges bent backwards the faceplate is connectable.

Fig. 2a-c Querschnitte von Abdeckplatten ohne Schallabsorp­ tionsschicht mit unterschiedlicher Ausführung des Plattenrands. Fig. 2a-c cross-sections of cover plates without sound absorption layer with different versions of the plate edge.

Die Abdeckplatte 1 besteht im wesentlichen aus einer mit aus­ gestanzten Durchbrüchen 22 versehenen Sichtplatte 2, einer aus einem Faservlies bestehenden schalldurchlässigen Zwischen­ schicht 3, einem Wabengitter 4, einer mit ausgestanzten Durch­ brüchen 52 versehenen Versteifungsplatte 5 sowie einer aus Mineralwolle bestehenden Schallabsorptionsschicht 6.The cover plate 1 consists essentially of a face plate 2 provided with punched openings 22 , a sound-permeable intermediate layer 3 consisting of a fiber fleece, a honeycomb grid 4 , a stiffening plate 5 provided with punched openings 52 and a sound absorption layer 6 made of mineral wool.

Die Sichtplatte 2, die Zwischenschicht 3, das Wabengitter 4 sowie die Versteifungsplatte 5 sind unter Bildung einer biegesteifen Sandwichplatte miteinander verklebt, wobei die Durchbrüche 22 und 52 in der Sichtplatte 2 und der Verstei­ fungsplatte 5 mit den Öffnungen des Wabengitters 4 kommuni­ zierende Kanäle bilden, durch welche die Schallwellen von der Vorderseite der Sichtplatte 2 zur Schallabsorptionsschicht 6 gelangen.The face plate 2, the intermediate layer 3, the honeycomb lattice 4 and the reinforcing plate 5 are bonded together to form a bending-resistant sandwich board, said openings 22 and 52 formed in the face plate 2 and the auctioning Fung plate 5 with the openings of the honeycomb grid 4 communi ornamental channels, through which the sound waves reach the sound absorption layer 6 from the front of the viewing panel 2 .

Die Sichtplatte 2 der in Fig. 1 dargestellten Abdeckplatte 1 wird von einem dünnen Aluminiumblech gebildet, dessen Rän­ der 24 unter Bildung einer Art Wanne rechtwinklig nach hinten umgebogen und mit Schlitzen 26 und Bohrungen 28 zum Einhängen von Halte- oder Abhängevorrichtungen bzw. zum Anbringen von Abdeckplatten-Verbindungselementen versehen sind. Die Ränder 24 sind so breit, daß sie über die Schallabsorptionsschicht 6 überstehen.The face plate 2 of the cover plate 1 shown in Fig. 1 is formed by a thin aluminum sheet, the knurled 24 perpendicularly bent to form a kind of trough to the rear and with slots 26 and holes 28 for hanging the holding or hanging devices or for the attachment of Cover plate connecting elements are provided. The edges 24 are so wide that they protrude beyond the sound absorption layer 6 .

Die Zwischenschicht 3 besteht aus einem dünnen Glasfaservlies, dessen der Sichtplatte 2 zugewandte Vorderseite mit Alumi­ nium bedampft ist. Das Glasfaservlies dient zum einen als Rieselschutz und verhindert den Durchtritt von Mineralwolle­ partikeln aus der Schallabsorptionsschicht 6 in den Raum vor der Sichtplatte 2. Zum anderen bildet das Glasfaservlies eine schalldurchlässige, als Sichtverkleidung für das Wabengitter 4 dienende Abdeckung der Durchbrüche 22 in der Sichtplatte 2. The intermediate layer 3 consists of a thin glass fiber fleece, the face plate 2 facing the front is vapor-coated with aluminum. The glass fiber fleece serves as a trickle protection and prevents the passage of mineral wool particles from the sound absorption layer 6 into the space in front of the faceplate 2 . On the other hand, the glass fiber fleece forms a sound-permeable cover for the openings 22 in the faceplate 2 , which serves as a covering for the honeycomb grid 4 .

Das Wabengitter 4 weist eine Vielzahl gleichartiger, unter Bildung eines Rippenprofils in Längsrichtung jeweils abwech­ selnd um ca. 120° über ihre Breitseiten abgebogener Folien­ streifen 42, 42′, 42′′ auf. Dabei ist jeweils ein Folienstrei­ fen 42 unter Bildung wabenförmiger Durchbrüche mit seinen beiden Nachbarstreifen 42′ und 42′′ verklebt. Die Rippen 46 des Folienstreifens 42 sind gegenüber den Rippen 46′ und 46′′ der parallel zueinander angeordneten Nachbarstreifen 42′ und 42′′ in Streifenlängsrichtung verschoben, wodurch der Streifen 42 abwechselnd mit einem Flächenabschnitt seiner beiden Breit­ seiten an einem Flächenabschnitt jedes seiner Nachbarstreifen 42′ und 42′′ anliegt. Zwischen den aneinander anliegenden Flächenabschnitten befindet sich eine Klebstoffschicht. An­ stelle eines Rippenprofils können die Folienstreifen auch ein Wellen- oder Zickzackprofil aufweisen, wobei die Verbindung der Folienstreifen untereinander analog erfolgt.The honeycomb grid 4 has a multiplicity of the same, with the formation of a rib profile in the longitudinal direction, alternating in each case alternating by about 120 ° over its broad sides bent films 42 , 42 ', 42 ''. In this case, a foil strip 42 is glued to form honeycomb openings with its two neighboring strips 42 'and 42 ''. The ribs 46 of the film strip 42 are shifted in relation to the ribs 46 'and 46 ''of the adjacent strips 42 ' and 42 '' in the longitudinal direction of the strip, as a result of which the strip 42 alternates with a surface section of its two broad sides on a surface section of each of its neighboring strips 42 'And 42 ''is applied. There is an adhesive layer between the abutting surface sections. Instead of a rib profile, the film strips can also have a corrugated or zigzag profile, the connection of the film strips to one another taking place analogously.

Die Versteifungsplatte 5 wird ebenso wie die Sichtplatte 2 von einem dünnen Aluminiumblech mit kreisförmig ausgestanzten Durchbrüchen 52 gebildet. Die Schallabsorptionsschicht 6 be­ steht aus einer Lage Mineralwolle oder aus einem anderen schallschluckenden Material.The stiffening plate 5 , like the faceplate 2, is formed from a thin aluminum sheet with circular perforations 52 . The sound absorption layer 6 is made of a layer of mineral wool or another sound absorbing material.

Zur Herstellung der Sandwichplatte aus Sichtplatte 2, Zwi­ schenschicht 3, Wabengitter 4 und Versteifungsplatte 5 wird zuerst die Rückseite der Sichtplatte 2 mit einem Klebstoff beschichtet und das Faservlies 3 aufgelegt. Weiter werden die vorderen Randkanten 48 der das Wabengitter 4 bildenden Folienstreifen 42, 42′, 42′′ mit einem Klebstoff bestrichen und das Wabengitter 4 mit der Rückseite der mit der Zwischen­ schicht 3 versehenen Sichtplatte 2 zusammengefügt. Anschließend wird die auf ihrer dem Wabengitter 4 zugewandten Seite eben­ falls mit einem Klebstoff beschichtete Versteifungsplatte 5 auf das Wabengitter 4 aufgelegt, auf dessen Folienstreifen 42, 42′, 42′′ entlang ihrer hinteren Randkante 48′ zuvor ein Klebstoff aufgetragen wurde. Diese Vorgehensweise gewährlei­ stet, daß die Zwischenschicht 3 nur dort mit Klebstoff in Berührung kommt, wo sie entweder an der Rückseite der Sicht­ platte 2 oder an den vorderen Randkanten 48 des Wabengitters 4 anliegt.To produce the sandwich panel made of faceplate 2 , intermediate layer 3 , honeycomb grid 4 and stiffening plate 5 , the back of faceplate 2 is first coated with an adhesive and the nonwoven fabric 3 is placed on top. Furthermore, the front edge 48 of the honeycomb grid 4 forming film strips 42 , 42 ', 42 ''are coated with an adhesive and the honeycomb grid 4 is joined to the back of the intermediate plate 3 provided with the face plate 2 . Subsequently, on its side facing the honeycomb grid 4, if the reinforcement plate 5 coated with an adhesive is placed on the honeycomb grid 4 , on its film strips 42 , 42 ', 42 ''along its rear edge 48 ', an adhesive was previously applied. This procedure ensures that the intermediate layer 3 only comes into contact with adhesive where it is either plate 2 on the back of the view or on the front edge 48 of the honeycomb grid 4 .

Nach Fertigstellung der Sandwichplatte wird die Rückseite der Versteifungsplatte 5 mit einem Klebstoff versehen und die Schallabsorptionsschicht 6 aufgeklebt.After completion of the sandwich panel, the back of the stiffening plate 5 is provided with an adhesive and the sound absorption layer 6 is glued on.

Die in den Fig. 2a-c dargestellten Abdeckplatten weisen unterschiedliche seitliche Begrenzungen auf. Bei der in Fig. 2a dargestellten Abdeckplatte ist der Rand 24 der Sichtplatte 2 die Zwischenschicht 3, das Wabengitter 4, sowie die Ver­ steifungsplatte 5 übergreifend nach hinten abgebogen und liegt gegen die Rückseite der Versteifungsplatte 5 an.The cover plates shown in FIGS. 2a-c have different lateral boundaries. In the illustrated in Fig. 2a cover the edge 24 of the face plate 2, the intermediate layer 3, the honeycomb lattice 4, as well as the Ver steifungsplatte 5 across bent backward and abuts against the back of the reinforcing plate 5 at.

In Fig. 2b ist eine Abdeckplatte mit einem zwischen Zwischen­ schicht 3 und Abdeckplatte 5 eingesetzten als Kantenschutz 30 dienenden Rechteckprofil dargestellt. Der in Fig. 2c dar­ gestellte Kantenschutz 30 weist zusätzlich eine umlaufende Nut 32 zur Aufnahme von Montageclips 34 auf, mit denen sich jeweils zwei Platten untereinander verbinden lassen.In Fig. 2b, a cover plate with an intermediate layer 3 and cover plate 5 used as edge protection 30 serving rectangular profile is shown. The edge protector 30 shown in FIG. 2c additionally has a circumferential groove 32 for receiving mounting clips 34 , with which two plates can be connected to one another.
