Description

Die Erfindung bezieht sich auf ein Hängeelement für Kulissendecken nach dem Oberbegriff des Patentanspruchs 1The invention relates to a hanging element for backdrop ceilings according to the preamble of claim 1

Die bekannten Hängeelemente für Kulissendecken dieser Ausbildung ( W. Schirmer, Lärmbekämpfung, Verlag Tribüne, Berlin, 1979 ) sind prismenförmige Akustikbalken, die zur Deckenauskleidung in Industriebauten benutzt und gleich­zeitig als begehbare Zwischendecke verwendet werden. Ihre Sichtabdeckung besteht aus einer perforierten PVC-Folie. Diese Veröffentlichung macht jedoch keine Aussagen über eine besondere Formgebung und Anordnung der senkrechten, zur Bildung des T-förmigen Trägers dienenden Platte; es muss vielmehr angenommen werden, dass die Platte ein ebenes Gebilde ist und eine Vergrösserung der Spannweite dieser Elemente nur durch eine Veränderung der Plattenabmessungen erreichbar ist.The well-known hanging elements for backdrop ceilings of this training (W. Schirmer, Noise Control, Verlag Tribüne, Berlin, 1979) are prism-shaped acoustic beams that are used for ceiling lining in industrial buildings and at the same time are used as a walk-in false ceiling. Your view cover consists of a perforated PVC film. However, this publication makes no statements about a special shape and arrangement of the vertical plate used to form the T-shaped support; on the contrary, it must be assumed that the plate is a flat structure and that the span of these elements can only be increased by changing the plate dimensions.

Die Hängeelemente für Kulissendecken der eingangs erwähnten Art haben sich zwar bewährt, je­doch ist es nicht möglich, sie für grössere Spann­weiten zu benutzen ausgehend von der Tatsache, dass die obigen Hängeelemente mittels strangförmiger Befestigungen aufgehängt werden, die oben an den Elementen angreifen. Es versteht sich, dass die Montagearbeiten dann am günstigsten sind und eine Aufhängung im Regel­falle dann einfacher auszuführen ist, wenn die Hängeelemente über eine möglichst grosse Länge verfügen.The hanging elements for backdrop ceilings of the type mentioned at the outset have proven their worth, but it is not possible to use them for larger spans based on the fact that the above hanging elements are suspended by means of rope-shaped fastenings which engage the elements at the top. It goes without saying that the assembly work is then the cheapest and a suspension is generally easier to carry out if the hanging elements have the greatest possible length.

Der Erfindung liegt die Aufgabe zugrunde, die Hängeelemente nach dem Gattungsbegriff des Patentanspruchs 1 so aus­zubilden, dass sie eine grössere länge erhalten und demgemäss einfacher montiert werden können. Angestrebt werden weiterhin geringe Ge­stehungskosten für die Hängeelemente, die über ein ausgezeichnetes Schallabsorptionsvermögen verfügen.The invention has for its object to design the hanging elements according to the preamble of claim 1 so that they have a greater length and can therefore be assembled more easily. The aim continues to be low production costs for the hanging elements, which have excellent sound absorption properties.

Diese Aufgabe wird durch die im Kennzeichnungsteil des Patentanspruchs 1 erwähnten Merkmale gelöst; vorteilhafte Ausgetaltungen der Erfindung ergeben sich dabei aus den Unteransprüchen.This object is achieved by the features mentioned in the characterizing part of patent claim 1; advantageous embodiments of the invention result from the subclaims.

Eine solche Ausführung der Hängeelemente ermöglicht Spannweiten bis etwa 15 m, ohne befürchten zu müssen, dass unerwünschte Verformungen und Verwerfungen eintreten. Besonders zweckmässig ist, dass die erwähnte Platte im Inneren des Hängeelementes eine besondere Gestalt erhält; sie soll nicht eben, sondern - bei Betrachtung von oben bzw. im waagerechten Schnitt - wellenförmig oder zickzackförmig ausgeführt sein, wobei die Wellen auch quadratisch, rechteckig oder trapezförmig ausge­führt sein können. Die so ausgeführten Platten werden dann örtlich mittels Niete od. dgl. fest mit den oben liegenden Metallprofilen verbunden, um so einen T-Träger entstehen zu lassen.Such a design of the hanging elements enables spans of up to approximately 15 m without fear of undesired deformations and distortions. It is particularly expedient that the plate mentioned takes on a special shape in the interior of the hanging element; it should not be flat, but - when viewed from above or in a horizontal section - be designed in a wave-like or zigzag shape, the waves also being square, rectangular or trapezoidal. The plates designed in this way are then firmly connected locally to the metal profiles located above by means of rivets or the like, in order to create a T-beam.

Dabei kann auch am unteren Ende ein etwa u-förmiges Profil aus Metall vorgesehen sein, das das untere Ende der im vorgenannten Sinne geformten Platte umschliesst. Auch dieses Profil wird zweckmässigerweise fest z.B. durch Nieten mit der Platte verbunden.An approximately U-shaped profile made of metal can also be provided at the lower end, which encloses the lower end of the plate shaped in the aforementioned sense. This profile is also expediently fixed e.g. connected to the plate by riveting.

Eine Abwandlung des erfindungsgemässen Hängeelementes sieht eine besondere Ausführung eines am unteren Rand des Hängeelementes befindlichen Metallprofils vor. Dies kann aufgrund der Erfindung so gestaltet sein, dass es zusammen mit dem vorerwähnten T-Profil ein Doppel-T-Profil bildet, wobei wiederum auch das unten liegende Metallprofil so ausgeführt wird, dass es sich vorwiegend waagerecht erstreckt. Zudem wird auch dieses Profil schiebe- und zugfest mit der mittig angeordneten Platte verbunden. Auch hier kommt eine Nietung in Betracht, was insb. bei den verwendeten dünnwandigen Aluminiumwerkstoffen zweckmässig ist.A modification of the hanging element according to the invention provides for a special design of a metal profile located at the lower edge of the hanging element. Based on the invention, this can be designed in such a way that it forms a double T profile together with the aforementioned T profile, the metal profile below also being designed such that it extends predominantly horizontally. In addition, this profile is also connected to the centrally arranged plate so that it cannot slide and pull. Riveting is also an option here, which is particularly useful for the thin-walled aluminum materials used.

Hängeelemente dieser Art werden zur Reduzierung des Schall­pegels z.B. in Produktionsräumen benutzt, sie werden als Kulissen unter die Decke der Räume gehängt, wozu Drähte, Seile od. dgl. dienen können, die oben an den Elementen angreifen. Die Elemente sind also nicht unterfangen bzw. von unten her unterstützt, weil dies bei einer Anordnung unter einer Decke ausgeschlossen ist. Zudem müssen die Hängeelemente leicht, zugleich aber auch biegesteif sein, um sie freitragend über grössere Längen hinweg aufhängen und montieren zu können.Hanging elements of this type are used to reduce the sound level e.g. used in production rooms, they are hung as a backdrop under the ceiling of the room, which can be used for wires, ropes or the like, which attack the elements at the top. The elements are therefore not underpinned or supported from below, because this is impossible with an arrangement under a ceiling. In addition, the hanging elements must be light, but at the same time rigid, so that they can be suspended and assembled over longer lengths in a self-supporting manner.

Ein wesentlicher Bestandteil dieser Elemente sind vorwiegend seitlich angeordnete plattenförmige Körper 1, die auch oben befindliche waagerechte Abschnitte 2 und unten ange­ordnete Abschnitte 3 aufweisen können, wobei eine Form­gebung durch Abwinkeln einer grösseren Platte möglich ist. Diese Körper 1 bestehen vorzugsweise aus Mineralfasern, die aufkaschierte Deckschichten haben, um gewünschte Ober­ flächeneigenschaften erhalten zu können.An essential component of these elements are predominantly laterally arranged plate-shaped bodies 1, which can also have horizontal sections 2 located at the top and sections 3 arranged at the bottom, wherein shaping is possible by angling a larger plate. These bodies 1 are preferably made of mineral fibers, which have laminated cover layers to desired upper to be able to maintain surface properties.

Um die gewünschten Trägereigenschaften zu erzielen, zugleich aber auch mit diesen Körpern 1 ein gutes Schallschluckvermögen zu erreichen, wird am oberen Rand des Hängeelementes ein Profil 4 aus Leichtmetall od. dgl. vorgesehen, an dem normalerweise auch die Aufhängeeelemente angreifen, welche nicht näher darge­stellt sind. Das Profil 4 wird von einer oben liegen­den Platte 5 gebildet, das mit zwei im Abstand von einer angeordneten Schenkeln 6 ausgestattet ist, die nach unten gerichtet sind. In den Raum zwischen den beiden Schenkeln 6 greift ein aus Leichtmetall od. dgl. be­stehendes Blech 7 ein, das wellenförmig gestaltet ist und gemäss Fig. 2 aufeinanderfolgende trapezförmige Einpressungen 8 aufweist, die seitlich abwechselnd angeordnete ebene Abschnitte 9 bilden, welche innen an den Schenkeln 6 anliegen und zudem auch am unteren Ende an den nach oben gerichteten Schenkeln 10 eines durchgehenden, ununterbrochen über die Länge der Hänge­elemente U-Profils 11 zur Anlage kommen. Dabei sind die Abschnitte 9 sowohl oben als auch unten an den Profilen 4 bzw. 11 durch Niete 12 schiebe- und zugfest angeord­net.In order to achieve the desired carrier properties, but at the same time to achieve a good sound absorption capacity with these bodies 1, a profile 4 made of light metal or the like is provided at the upper edge of the hanging element, to which the suspension elements, which are not shown in more detail, normally also act . The profile 4 is formed by an overhead plate 5, which is equipped with two spaced apart legs 6, which are directed downwards. A sheet 7 made of light metal or the like engages in the space between the two legs 6, which is designed in a wave shape and, as shown in FIG. 2, has successive trapezoidal press-ins 8 which form laterally alternating planar sections 9, which on the inside of the legs 6 rest and also come to rest at the lower end on the upward legs 10 of a continuous, uninterrupted over the length of the hanging elements U-profile 11. The sections 9 are arranged both on the top and bottom of the profiles 4 and 11 by rivets 12 push and pull resistant.

Wie Fig. 1 erkennen lässt, liegen die Abschnitte 2 innen am Profil 4 und die Abschnitte 3 unten am Steg des Profils 11 an. Damit befinden sich auch die seitlich angeordneten Körper 1 im Abstand von dem mittig angeordneten Blech 7. Diese Ausbildung führt zu einer sehr guten Schallschluckeigenschaft, gleichzeitig bilden die Profile 4 und 11 zusammen mit dem profilierten Blech 7 einen T-Träger, der dem Hängeelement eine gute Biege­steifigkeit gegen Durchbiegen verleiht und Spannweiten von 15 m zulässt. Dabei kann die Breite der Platte 5 auch so gering gehalten werden, dass nur ein Teil der Abschnitte 2 überdeckt ist. So können die seitlichen Ränder der Platte 5 auch bei x enden.As can be seen in FIG. 1, the sections 2 lie on the inside of the profile 4 and the sections 3 on the bottom of the web of the profile 11. So that the laterally arranged body 1 are at a distance from the centrally arranged plate 7. This design leads to very good sound absorption properties, at the same time the profiles 4 and 11 together with the profiled plate 7 form a T-beam, which the hanging element a good one Bending rigidity against bending gives and spans of 15 m. The width of the plate 5 also be kept so low that only part of the sections 2 is covered. So the side edges of the plate 5 can also end at x.

Anstelle des Bleches 7 gemäss Fig. 1 und 2 kann auch ein sinusförmig gestaltetes Blech 7 gemäss Fig. 3 benutzt werden. Es ist sinngemäss oben und unten starr mit den angrenzenden Metallteilen zu verbinden.Instead of the plate 7 according to FIGS. 1 and 2, a sinusoidally shaped plate 7 according to FIG. 3 can also be used. It is appropriate to rigidly connect the adjacent metal parts at the top and bottom.

Bei der Ausführung gemäss Fig. 4 ist auch unten am Hänge­element ein Leichtmetallprofil vorgesehen, das dem Profil 4 entsprechend ausgeführt ist, zusätzlich aber noch seitlich nach oben abgewinkelte Ränder 13 aufweist, um die Körper 1 besser halten zu können. Da das Blech 7 wiederum sowohl am unteren als auch am oberen Rand fest mit den Profilen 4 verbunden ist, ergibt sich ein Doppel-T-Träger.In the embodiment according to FIG. 4, a light metal profile is also provided at the bottom of the hanging element, which is designed according to the profile 4, but additionally has edges 13 which are angled laterally upwards, in order to be able to hold the body 1 better. Since the sheet 7 is in turn firmly connected to the profiles 4 at both the lower and the upper edge, a double-T beam results.

Fig. 5 zeigt ebenfalls einen Doppel-T-Träger mit den Profilen 4 und dem Blech 7 zusammen mit nur seitlich angeordneten schallschluckenden Platten in Form der Körper 1.Fig. 5 also shows a double-T beam with the profiles 4 and the sheet 7 together with only laterally arranged sound absorbing plates in the form of the body 1st

Die Ausführungsform gemäss Fig. 6 zeigt eine angewandelte Ausführung für den unteren Rand der Hängelemente. Das Profil 11 gemäss Fig. 1 hat noch durch einen t-förmigen Ansatz 14 zur Aufnahme der unteren Abschnitte 3.The embodiment according to FIG. 6 shows a modified version for the lower edge of the hanging elements. The profile 11 according to FIG. 1 also has a t-shaped projection 14 for receiving the lower sections 3.

Gemäss Fig. 7 hat das oben liegende Profil 4 zwischen den Körpern 1 und dem Blech 7 Hohlstellen 15, und zwar zur Bildung von hohlen, längsverlaufenden kastenartigen Trägern. Diese oben liegenden Profile 4 zeichnen sich durch eine gesteigerte Steifigkeit in senkrechter und waagerechter Richtung aus.
Bei allen Ausführungsformen können die Körper 1 auch nahe an der Platte 7 angeordnet sein und diese ggfs. berühren.According to FIG. 7, the upper profile 4 has hollow points 15 between the bodies 1 and the sheet metal 7, specifically for the formation of hollow, longitudinal box-like supports. These overhead profiles 4 are characterized by increased rigidity in the vertical and horizontal directions.
In all embodiments, the bodies 1 can also be arranged close to the plate 7 and, if necessary, touch it.
