Abstract

The element (6) has a profile (7) with bent-off portions (9), on which a panel (13), provided with holes, is releasably fastened. The bent-off portions (9) have stamped-out sections (8) for suspending the element on a substructure. The panel (13) is produced, for example, from wood and has parallel grooves (15, 16) which form through-passages at the points of intersection. Due to the difference in material between the panel (15) and the profile (7), a better sound-absorption capacity in the low-frequency range is achieved. The profile (7) can be mechanically produced in a very simple manner and, due to its high stability, permits the production of comparatively large elements which are, nevertheless, of low weight. <IMAGE>

Description

Die Erfindung betrifft ein schallabsorbierendes Element für die Raumgestaltung, mit einer schallabsorbierende Durchgangslöcher aufweisenden Platte und mit einer Halterung zur Befestigung der Platte an einer Gebäudewand, insbesondere einer Decke.The invention relates to a sound-absorbing element for interior design, with a sound-absorbing through-hole plate and with a holder for fastening the plate to a building wall, in particular a ceiling.

Ein bekanntes Element dieser Art weist eine schallabsorbierende Platte gemäss der EP-A-0 388 355 auf. Diese Platte ist insbesondere eine furnierte Spannplatte und weist auf beiden Seiten parallele Nuten auf. Die Kreuzungspunkte der Nuten bilden Löcher, durch welche nach dem Helmholtz-Effekt schallabsorbiert wird. Die Platte weist insbesondere im Bereich der meist besonders störenden hohen Frequenzen gute akustische Eigenschaften auf. Diese Platten wurden bisher mit einem Holzrahmen an einer Gebäudewand befestigt. Es wurden hier jeweils zwei Platten im Abstand zueinander zusammengefasst. Der Hohlraum zwischen den Platten wurde in der Regel mit wärmedämmendem Material, beispielsweise Glaswolle oder Steinwolle ausgefüllt. Bei diesen im wesentlichen aus zwei Platten und einem Holzrahmen bestehenden Element besteht insbesondere die Schwierigkeit, dass es bei vertretbarem Gewicht aus Stabilitätsgründen nur kleinformatig herstellbar ist. Bei einer Länge von beispielsweise 3 m, die besonders geeignet wäre, hätte das Element ein Gewicht bei dem es nur mit Mühe an einer Decke montiert werden könnte.A known element of this type has a sound absorbing plate according to EP-A-0 388 355. This plate is in particular a veneered clamping plate and has parallel grooves on both sides. The crossing points of the grooves form holes through which sound is absorbed according to the Helmholtz effect. The plate has good, especially in the area of the mostly particularly disturbing high frequencies acoustic properties. Until now, these panels were attached to a building wall with a wooden frame. Two plates were combined at a distance from each other. The cavity between the panels was usually filled with insulating material, such as glass wool or rock wool. In this element, which essentially consists of two plates and a wooden frame, there is the particular difficulty that it can only be produced in a small format for reasons of stability for an acceptable weight. With a length of, for example, 3 m, which would be particularly suitable, the element would have a weight in which it would be difficult to mount it on a ceiling.

Der Erfindung liegt die Aufgabe zugrunde, ein Element der genannten Art zu schaffen, das in grösserem Format, beispielsweise einer Länge von 3 m, herstellbar ist und das bei wesentlich grösserer Stabilität leichter ist und das trotzdem kostengünstig hergestellt werden kann. Die Aufgabe ist durch die Erfindung gemäss Anspruch 1 gelöst.The invention has for its object to provide an element of the type mentioned, which can be produced in a larger format, for example a length of 3 m and which is lighter with much greater stability and which can nevertheless be produced inexpensively. The object is achieved by the invention according to claim 1.

Beim erfindungsgemässen Element ist die Halterung durch ein Profil gebildet, an welchem die Platte befestigt ist. Das Profil weist Mittel zu seiner Befestigung an einer Gebäudewand auf. Die schallabsorbierende Platte wird somit mittels eines Profils an einer Gebäudewand befestigt. Solche Profile können in bekannter Weise maschinell mit hoher Präzision und sehr kostengünstig hergestellt werden. Die Abkantungen verleihen der Kassette bei geringem Gewicht eine hohe Stabilität.In the element according to the invention, the holder is formed by a profile to which the plate is attached. The profile has means for fastening it to a building wall. The sound-absorbing panel is thus attached to a building wall using a profile. Such profiles can be machined in a known manner with high precision and can be produced very inexpensively. The bevels give the cassette a high stability with a low weight.

Das Profil ist nach einer Weiterbildung der Erfindung aus Metallblech hergestellt. Solche Profilbleche sind an sich bekannt. Beim erfindungsgemässen Element wurde nun überraschend festgestellt, dass im Tieftonbereich eine bessere Absorptionsfähigkeit erreicht werden kann. Massgebend dazu dürften die unterschiedlichen Eigenfrequenzen sein, welche das Profilblech und die Holzplatte aufweisen. Zudem ist das erfindungsgemässe Element dann, wenn das Profil aus Metallblech hergestellt ist, in hohem Masse feuerhemmend und feuerbeständig, was beim vorbekannten Element gar nicht der Fall war.According to a further development of the invention, the profile is made from sheet metal. Such profile sheets are known per se. With the element according to the invention, it has now surprisingly been found that a better absorption capacity can be achieved in the low-frequency range. Decisive for this are the different natural frequencies that the profiled sheet and the wooden plate have. In addition, when the profile is made of sheet metal, the element according to the invention is highly fire-retardant and fire-resistant, which was not the case with the previously known element.

Das erfindungsgemässe Element kann bei seiner Montage sehr einfach an einem gängigen unsichtbaren Tragprofil eingehängt werden. Hierbei kann die Platte bei einer Deckenverkleidung unten, das heisst sichtbar, oder verdeckt angeordnet werden. Im zweiten Fall ist dann das Profil sichtbar. Mit demselben Element kann somit eine Holz- oder eine Metallverkleidung oder eine gemischte Verkleidung erstellt werden, ohne dass spezielle Befestigungsmittel oder andere Befestigungsarten notwendig sind.The element according to the invention can be very easily attached to a common invisible support profile during its assembly. In this case, the panel can be arranged at the bottom of a ceiling cladding, that is to say visible, or concealed. In the second case, the profile is then visible. A wooden or metal cladding or a mixed cladding can thus be created with the same element without the need for special fasteners or other types of fastening.

Die Platte kann lösbar auf die Abkantungen des Profils aufgeschoben sein, was ein einfaches Auswechseln oder eine Reparatur der Platte ermöglicht.The plate can be releasably pushed onto the folds of the profile, which makes it easy to replace or repair the plate.

Die Fig. 1 zeigt ein schallabsorbierendes Element 6, das aus einem Profil 7, einer ebenen schallabsorbierenden Platte 13 und einer zwischen diesen angeordneten Wärmeisolationsmatte 17 besteht. Das Profil 7 ist vorzugsweise aus Metallblech hergestellt und besitzt eine ebene Frontseite 12 und parallele seitliche Abkantungen 9 sowie Abkantungen 10. Das Profil 7 ist vorzugsweise rechteckig mit einer Länge von beispielsweise 3 m ausgebildet. Die Breite der beiden Abkantungen 9 beträgt beispielsweise 4 cm, kann aber in einem weiten Bereich an die jeweiligen Isolationsanforderungen angepasst werden. Ein solches Profil 7 kann maschinell mit Abkantpressen sehr einfach und dennoch mit sehr kleinen Masstoleranzen hergestellt werden. Auch bei geringer Materialstärke wird durch die Abkantungen 9 und 10 eine sehr gute Stabilität erreicht.1 shows a sound-absorbing element 6, which consists of a profile 7, a flat sound-absorbing plate 13 and a heat insulation mat 17 arranged between them. The profile 7 is preferably made of sheet metal and has a flat front side 12 and parallel lateral bends 9 and bends 10. The profile 7 is preferably rectangular with a length of, for example, 3 m. The width of the two bevels 9 is, for example, 4 cm, but can be in a wide range be adapted to the respective insulation requirements. Such a profile 7 can be machined very easily with press brakes and yet with very small dimensional tolerances. Even with a low material thickness, the bevels 9 and 10 achieve very good stability.

Die Platte 13 weist sich kreuzende V-förmige Nuten 15 und 16 auf. Die Tiefen der Nuten 15 und 16 sind so gewählt, dass an den Schnittstellen die Platte durchbrochen ist. Die Herstellung und die Eigenschaften einer solchen Platte 13 sind in der EP-A-0 388 355 beschrieben. Die Platte 13 kann jedoch auch eine übliche Lochplatte sein. Die Platte 13 sollte jedoch aus einem spezifisch leichten Werkstoff, beispielsweise Holz oder einem geeigneten Kunststoff hergestellt sein. Dadurch wird erreicht, dass die Platte 13 und das Profil 7 unterschiedliche Eigenfrequenzen aufweisen und damit eine gute Absorptionsfähigkeit erreicht wird.The plate 13 has intersecting V-shaped grooves 15 and 16. The depths of the grooves 15 and 16 are chosen so that the plate is broken through at the interfaces. The production and the properties of such a plate 13 are described in EP-A-0 388 355. However, the plate 13 can also be a conventional perforated plate. The plate 13 should, however, be made of a specifically light material, for example wood or a suitable plastic. It is thereby achieved that the plate 13 and the profile 7 have different natural frequencies and thus a good absorption capacity is achieved.

Die Platte 13 weist auf der Rückseite zwei parallele, im Querschnit L-förmige Leisten 14 auf, die an der Platte 13 befestigt sind und mit denen die Platte 13 lösbar mit dem Profil 7 verbunden ist. Wie aus Fig. 1 ersichtlich, weisen dazu die Abkantungen 9 jeweils einen Rückbug 19 auf, welche die Leisten 14 hintergreifen. Die Platte 13 kann mit den Leisten 14 in Längsrichtung der Abkantungen 9 verschoben und damit vom Profil 7 getrennt werden. Die Schicht 17 besteht beispielsweise aus Steinwolle oder Glaswolle und ist in der Regel durch Klemmung zwischen der Platte 13 und dem Profil 7 hinreichend fixiert.The plate 13 has on the back two parallel, cross-sectionally L-shaped strips 14 which are fastened to the plate 13 and with which the plate 13 is detachably connected to the profile 7. As can be seen from FIG. 1, the bevels 9 each have a rear bend 19 which engages behind the strips 14. The plate 13 can be moved with the strips 14 in the longitudinal direction of the folds 9 and thus be separated from profile 7. The layer 17 consists, for example, of rock wool or glass wool and is generally adequately fixed by clamping between the plate 13 and the profile 7.

Die Befestigung des Elementes 6 an einer Deckenwand 1 kann beispielsweise gemäss Fig. 2 erfolgen. Auf einer an der Decke 1 befestigten Holzunterlage 2 sind mittels Holzschrauben 4 und Klemmblechen 3 ein im Querschnitt H-förmiges Tragprofil befestigt. Das Tragprofil 5 greift wie ersichtlich in Ausstanzungen 8 benachbarter Elemente 6 ein. Die Elemente 6 sind somit lösbar an Tragprofilen 5 aufgehängt. Bei der Ausführung nach Fig. 2 sind die Platten 13 unten und somit sichtbar angeordnet, während die Profile 7 verdeckt sind. Die Elemente 6 können aber ohne weiteres auch so eingehängt werden, dass die Platten 13 oben und damit verdeckt sind. Die Höhe der Deckenkonstruktion kann auch grösser gewählt werden, so dass der Zwischenraum zwischen der Deckenwand 1 und den Elementen 6 für das Verlegen von Kabeln, Rohren und dergleichen genutzt werden kann. Hierbei besteht ein wesentlicher Vorteil des erfindungsgemässen Elementes 6 darin, dass die Einzelelemente leicht ausgewechselt werden können und diese feuerhemmend sind. Durch die hohe Schalldämmung der Elemente 6 können sonst übliche Abschottungen im Zwischenraum zwischen der Gebäudewand 1 und den Elementen 6 wegfallen. Durch die hohe Massgenauigkeit der Kassetten 7 lassen sich Zwischenräume zwischen den Elementen 6 weitgehend vermeiden, so dass unschöne Schattenfugen und eine Schallübertragung durch Zwischenräume vermieden werden können.The element 6 can be attached to a ceiling wall 1, for example according to FIG. 2. On a wooden base 2 fastened to the ceiling 1, a support profile which is H-shaped in cross section is fastened by means of wood screws 4 and clamping plates 3. As can be seen, the support profile 5 engages in punched-out portions 8 of adjacent elements 6. The elements 6 are thus detachably suspended from the support profiles 5. In the embodiment according to FIG. 2, the plates 13 are arranged at the bottom and thus visibly, while the profiles 7 are covered. However, the elements 6 can also be easily hung in such a way that the plates 13 are covered at the top and thus. The height of the ceiling construction can also be chosen to be larger, so that the space between the ceiling wall 1 and the elements 6 can be used for the laying of cables, pipes and the like. Here, an essential advantage of the element 6 according to the invention is that the individual elements can be easily replaced and they are fire-retardant. Due to the high sound insulation of the elements 6, otherwise usual partitions in the space between the building wall 1 and the elements 6 can be omitted. Through the high dimensional accuracy of the cassettes 7, spaces between the elements 6 can be largely avoided, so that unsightly shadow gaps and sound transmission through spaces can be avoided.

Die Ausstanzungen 8 können aus akustischen oder statischen Gründen durch am Profil 7 angebrachte Laschen oder dergleichen (hier nicht gezeigt) ersetzt sein. Die Abkantungen 9 sind in diesem Fall nicht durch Ausstanzungen geschwächt bzw. für Schall stellenweise durchgängig, was bei bestimmten Anwendungen von Bedeutung sein kann.The cut-outs 8 can be replaced for acoustic or static reasons by tabs or the like (not shown here) attached to the profile 7. In this case, the bevels 9 are not weakened by punched-out areas or are partially continuous for sound, which can be important in certain applications.

Das Profil 7 ist vorzugsweise ein C-Profil, wobei die Abkantungen 10 fehlen können. Vorzugsweise ist das Profil 7 aus Metallblech, jedoch sind auch andere Werkstoffe denkbar, aus denen dünne Platten oder Folien herstellbar sind und die bei vergleichsweise geringem Gewicht eine hohe Stabilität besitzen.The profile 7 is preferably a C profile, and the folds 10 may be missing. Profile 7 is preferably made of sheet metal, but other materials are also conceivable from which thin plates or foils can be produced and which have a high level of stability with a comparatively low weight.
