Description

Die Erfindung betrifft eine Schallschutzeinlage für Montageschienen gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a soundproofing insert for mounting rails according to the Preamble of claim 1.

In der Installations- und Haustechnik kommen vielfach Montageschienen zum Einsatz. Die Montageschienen sind üblicherweise Blechprofile mit einem C-förmigen Profil und bieten einer Vielzahl von Verbindungselementen eine Anbindungsmöglichkeit. Der Vorteil von Montageschienen besteht darin, dass die Verbindungselemente überall entlang der Längserstreckung der Montageschienen montiert werden können. Vielfach werden Schienensysteme zusammengestellt, die beispielsweise von der Decke abhängen und als Auflager für Kabeltrassen, Rohre und Lüftungskanäle dienen. Bei vielen Anwendungen von Montageschienen ist es erforderlich, die Schiene und die daran befestigten oder darauf ruhenden Bauteile voneinander Schall-zu-entkoppeln. Dies ist beispielsweise bei Rechtecklüftungskanälen der Fall, die auf Systemen von Montageschienen ruhen. Ohne Schallisolierung würde das Geräusch der in den Luftschächten angeordneten Ventilatoren übertragen und könnte innerhalb eines Gebäudes zu einer Lärmbeeinträchtigung führen.Mounting rails are often used in installation and building services. The mounting rails are usually sheet metal profiles with a C-shaped profile and offer a variety of connecting elements a connection option. The The advantage of mounting rails is that the connecting elements are everywhere can be mounted along the length of the mounting rails. frequently rail systems are put together, for example from the ceiling depend and serve as a support for cable trays, pipes and ventilation ducts. at Many applications of mounting rails require the rail and the sound-decoupling components attached to or resting on them. This is the case, for example, with rectangular ventilation ducts based on systems from The mounting rails are at rest. Without soundproofing, the noise in the Air shafts arranged to transmit fans and could within one Cause noise pollution in the building.

Die bislang zur Schallisolation bekannten Schallschutzgummis bestehen aus einem flexiblen Material und weisen ein flaches Auflageteil auf, dessen Längsränder die Montageschiene an den Seitenwänden übergreifen. Ein vom Auflageteil abragendes Fussteil ist in die Öffnung der C-Profilschiene einsetzbar und hintergreift die die Öffnung berandenden Längskanten der Montageschiene. An der Oberfläche des Auflageteils verlaufen in Längsrichtung leistenartige Wülste parallel zueinander, die als Auflager für einen Lüftungskanal dienen. Zwei der leistenartigen Wülste sind im Bereich des Längsrandes des Schallschutzgummis angeordnet und stützen sich im montierten Zustand an den die Öffnung der Montageschiene berandenden Längskanten ab. Die anderen leistenartigen Wülste liegen über der Öffnung der C-Profilschiene. Alle leistenartigen Wülste weisen den gleichen Querschnitt auf und besitzen die gleiche Höhe. Ein auf einer mit einem Schallschutzgummi bestückten Montageschiene ruhender Lüftungskanal wird im wesentlichen nur von den beiden äusseren, parallel zum Längsrand des Schallschutzgummis verlaufenden, leistenartigen Wülsten unterstützt, da die über der Öffnung liegenden Wülste bei Belastung in das Innere der C-Profilschiene ausweichen können. Bei der Montage wird der Lüftungskanal oftmals axial hin- und hergeschoben. Da das Gewicht des Lüftungskanals im wesentlichen nur auf den leistenartigen Wülsten an den Längsrändem des Schallschutzgummis ruht, kann es bei der Querverschiebung des Lüftungskanals vorkommen, dass die Längsränder des Schallschutzgummis in Schieberichtung eingerollt werden und der Schallschutzgummi sich von der Montageschiene löst. Dies kann dazu führen, dass der Lüftungskanal ohne Zwischenlage des Schallschutzgummis auf der Montageschiene ruht und die beabsichtigte Schallentkopplung unwirksam wird.The soundproof rubbers known so far for sound insulation consist of a flexible material and have a flat support part, the longitudinal edges of which Reach over the mounting rail on the side walls. A protruding from the support part The foot section can be inserted into the opening of the C profile rail and engages behind the opening bordering longitudinal edges of the mounting rail. On the surface of the support part run in the longitudinal direction of strip-like beads parallel to each other, which act as supports for serve a ventilation duct. Two of the strip-like ridges are in the area of Longitudinal edge of the sound insulation rubber arranged and are supported in the assembled Condition on the longitudinal edges bordering the opening of the mounting rail. The other strip-like beads lie over the opening of the C profile rail. All strip-like beads have the same cross-section and have the same Height. A mounting rail resting on a soundproof rubber Ventilation duct is essentially only from the two outer, parallel to the Supported, strip-like beads running along the longitudinal edge of the soundproofing rubber, since the beads lying over the opening into the interior of the C-profile rail when loaded can dodge. When installing, the ventilation duct is often axially back and forth procrastinated. Since the weight of the ventilation duct essentially only on the strip-like beads resting on the longitudinal edges of the soundproofing rubber, it can the transverse displacement of the ventilation duct that the longitudinal edges of the Soundproof rubbers are rolled in the sliding direction and the soundproof rubber detaches from the mounting rail. This can lead to the ventilation duct being without Intermediate layer of soundproofing rubber rests on the mounting rail and the intended sound decoupling becomes ineffective.

Der bekannte Schallschutzgummi weist im Fussteil eine in Längsrichtung verlaufende Bohrung auf, die einen etwa kleeblattförmigen Querschnitt aufweist. Durch die Bohrung ist der Schallschutzgummi auf eine Gewindestange aufsteckbar. Diese Art der Schallisolation kann beispielsweise bei stirnseitigen Anbindungen an die Montageschiene erforderlich sein. Der Querschnitt der Bohrung erlaubt nur den Einsatz einer Gewindestange, deren Durchmesser genau auf den Durchmesser der Bohrung abgestimmt ist. Dadurch ist der Anwender in der Auswahl der stimseitigen Anbindungselemente eingeschränkt.The known soundproofing rubber has a longitudinally extending in the foot part Bore that has an approximately trefoil-shaped cross section. Through the hole the soundproof rubber can be plugged onto a threaded rod. That kind of Sound insulation can be used, for example, for front connections to the Mounting rail may be required. The cross section of the hole only allows use a threaded rod, the diameter of which corresponds exactly to the diameter of the bore is coordinated. As a result, the user is in the selection of the face end Connection elements restricted.

Aufgabe der vorliegenden Erfindung ist es daher, eine Schallschutzeinlage für Montageschienen mit C-förmigem Profil dahingehend zu verbessern, dass auch bei einer Manipulation eines sich auf der Schallschutzeinlage abstützenden Bauteils eine zuverlässige Schallentkopplung gewährleistet bleibt. Insbesondere soll ein Einrollen der Längsränder der Schallschutzeinlage und ein Lösen von der Montageschiene bei einem axialen Querverschieben des sich darauf abstützenden Bauteils verhindert werden. Die Schallschutzeinlage soll einfach an der Montageschiene montierbar sein. Sie soll platzsparend lagerbar und einfach in der Anwendung sein.The object of the present invention is therefore to provide a soundproofing insert for To improve mounting rails with a C-shaped profile so that even with one Manipulation of a component supported on the soundproofing insert reliable sound decoupling is guaranteed. In particular, curling should Longitudinal edges of the soundproofing insert and detachment from the mounting rail on one axial transverse displacement of the component supported thereon can be prevented. The Sound insulation insert should be easy to mount on the mounting rail. she should be space-saving and easy to use.

Diese Aufgaben werden erfindungsgemäss durch eine Schallschutzeinlage gelöst, welche die im kennzeichnenden Abschnitt des Patentanspruchs 1 angeführten Merkmale aufweist. Die Schallschutzeinlage für Montageschienen, insbesondere für C-Profilschienen mit im wesentlichen C-förmigem Querschnitt, besteht aus einem elastischen Material und umfasst ein Auflageteil, das eine Unterseite und herabgezogene Längsränder aufweist und an seiner Auflagefläche mit leistenartigen Wülsten ausgestattet ist, die parallel zueinander in Längsrichtung des Auflageteils verlaufen. An das Auflageteil ist ein Fussteil einstückig angeformt, das an seinen beiden Längsflanken je eine Schulter aufweist, die der Unterseite des Auflageteils gegenüberliegen, wobei das Fussteil im montierten Zustand innerhalb der C-Profilschiene angeordnet ist und die Schultern die die Öffnung der Schiene berandenden Längskanten hintergreifen. Das Fussteil ist mit einer in Längsrichtung verlaufenden Bohrung versehen. Eine Hüllfläche an die vom Fussteil abgewandte Auflagefläche des Auflageteils ist konvex gewölbt, wobei die leistenartigen Wülste an den Längsrändern des Auflageteils eine gringere Höhe aufweisen als der von ihnen eingeschlossene Bereich.According to the invention, these objects are achieved by a soundproofing insert, which the features stated in the characterizing section of claim 1 having. The soundproofing insert for mounting rails, especially for C profile rails with a substantially C-shaped cross section, consists of a elastic material and includes a support part that has a bottom and has drawn down longitudinal edges and on its contact surface with strip-like Beading is equipped, which is parallel to each other in the longitudinal direction of the support part run. A foot part is integrally formed on the support part, that on its two Longitudinal flanks each have a shoulder, which is the underside of the support part opposite, the foot part in the assembled state within the C-profile rail is arranged and the shoulders bordering the opening of the rail Reach behind the longitudinal edges. The foot part has a lengthwise one Provide hole. An enveloping surface on the contact surface of the The support part is convex, with the strip-like beads on the longitudinal edges of the support part have a greater height than the one enclosed by them Area.

Durch die erfindungsgemässe Aussenkontur der Auflagefläche des Auflageteils liegt ein von der an der C-Profilschiene montierten Schallschutzeinlage unterstütztes Bauteil, beispielsweise ein Recktecklüftungskanal, nicht bloss auf den leistenartigen Wülsten am Längsrand sondern auch in den Bereichen dazwischen auf der Auflagefläche auf. Die hochgewölbten Bereiche zwischen den leistenartigen Wülsten an den Längsrändern werden durch die Gewichtskraft des Bauteils niedergedrückt und gegen die Längsränder der C-Profilschiene gepresst. Die Gewichtskraft des Bauteils wird über die gesamte Auflagefläche verteilt. Dadurch kann das Bauteil quer zur Längsrichtung der C-Profilschiene geschoben werden, ohne dass sich die Längsränder der Schallschutzeinlage einrollen. Dadurch wird ein unbeabsichtigtes Abziehen des Schallschutzgummis von der C-Profilschiene durch die beim Verschieben des Bauteils auftretende Schubkraft verhindert.Due to the external contour of the support surface of the support part according to the invention component supported by the sound insulation insert mounted on the C-profile rail, for example a rectangular ventilation duct, not just on the strip-like beads Longitudinal edge but also in the areas in between on the contact surface. The domed areas between the strip-like beads on the longitudinal edges are depressed by the weight of the component and against the longitudinal edges of the C-profile rail. The weight of the component is over the entire Support area distributed. This allows the component to run transversely to the longitudinal direction of the C profile rail be pushed without the longitudinal edges of the Roll up the soundproofing insert. This will inadvertently pull the Soundproof rubbers from the C-profile rail by moving the component occurring thrust prevented.

Der vorteilhafte Effekt der erfindungsgemässen Ausbildung der Schallschutzeinlage wird dadurch unterstützt, dass die Auflagefläche zu beiden Seiten der an den Längsrändern verlaufenden leistenartigen Wülste schräg zu den herabgezogenen Längsrändern abfällt. Auf diese Weise legen sich die Längsränder der Schallschutzeinlage beim Querverschieben des Bauteils an die Seitenwände der C-Profilschiene an und wirken der Einrolltendenz entgegen.The advantageous effect of the inventive design of the sound insulation insert becomes supported by the fact that the contact surface on both sides of the on the longitudinal edges running strip-like ridges fall obliquely to the drawn longitudinal edges. In this way, the longitudinal edges of the soundproofing insert lay down Push the component against the side walls of the C profile rail and act Towards curl up.

In einer vorteilhaften Ausführungsvariante der Erfindung besitzt die Hüllfläche im Querschnitt etwa die Form einer Ellipsenhälfte. Dabei bildet die Axialprojektion der Längsränder der Schallschutzeinlage die Hauptscheitel der Ellipse. Indem die Aussenkontur der Auflagefläche zu einer Hüllkurve führt, deren Spur elliptisch ist, kann die Gewichtskraft besonders gut verteilt werden.In an advantageous embodiment of the invention, the envelope surface has Cross section about the shape of an ellipse half. The axial projection forms the Longitudinal edges of the sound insulation insert the main apex of the ellipse. By the The outer contour of the contact surface leads to an envelope curve, the track of which can be elliptical the weight is distributed particularly well.

Indem zwischen den leistenartigen Wülsten an den Längsrändern zwei weitere, parallel zu diesen und zueinander verlaufende, leistenartige Wülste angeordnet sind, die durch einen Materialsteg voneinander getrennt sind, dessen Höhe im wesentlichen der Höhe der leistenartigen Wülste an den Längsrändern entspricht, wird der mittlere Bereich der Anlagefläche des Schallschutzgummis bei Belastung gegen die die Öffnung berandenden Längskanten der C-Profilschiene gepresst und verspannt. Dies wirkt bei einem Querverschieben eines vom Schallschutzgummi unterstützen Bauteils einem ungewollten Abziehen des Schallschutzgummis von der C-Profilschiene entgegen.By placing two more parallel between the strip-like beads on the longitudinal edges to these and mutually extending, strip-like beads are arranged, which a web of material are separated from each other, the height of which is essentially the height corresponds to the strip-like beads on the longitudinal edges, the middle area of the Contact surface of the soundproof rubber when loaded against the opening bounding longitudinal edges of the C-profile rail pressed and braced. This works with a transverse displacement of a component supported by the sound insulation rubber against unwanted removal of the soundproofing rubber from the C-profile rail.

Indem die Längsflanken des Fussteils schräg zueinander verlaufen und von der Unterseite des Auflageteils abgewandt sind, kann das Fussteil des Schallschutzgummis besser in die Öffnung der C-Profilschiene eingeführt werden, bis es mit den Schultern die Längskanten der Schiene hintergreift. Dabei erweist sich ein Fügewinkel, den die Längsflanken des Fussteils miteinander einschliessen, von kleiner als 60° als vorteilhaft. Bei den gewählten Fügewinkeln gleiten die schrägen Längsflanken über die abgerundeten Blechkanten der die Öffnung berandenden Längskanten der C-Profilschiene.By running the longitudinal flanks of the foot part at an angle to each other and from the Bottom of the support part are facing away, the foot part of the soundproof rubber better be inserted into the opening of the C-profile rail until it is shouldered Reaches behind the longitudinal edges of the rail. This proves a joining angle that the Enclose longitudinal flanks of the foot part with each other, less than 60 ° as advantageous. With the selected joining angles, the oblique longitudinal flanks slide over the rounded sheet metal edges of the longitudinal edges of the C-profile rail bordering the opening.

In einer vorteihaften Variante der Erfindung weist der Querschnitt der Bohrung im Fussteil im wesentlichen die Form eines Drei-Viertel-Kreises auf, und die Bohrung ist an der dem Auflageteil abgewandten Seite des Fussteils von einem flexiblen Wandungsteil berandet, das in die Bohrung gewölbt ist und nach aussen umstülpbar ist, wobei die abgewandte Seite im Querschnitt eine im wesentlichen kreisbogenförmige Kontur aufweist. Durch das ausstülpbare flexible Wandungsteil kann sich die Bohrung bei Bedarf an Gewindebolzen unterschiedlicher Durchmesser anpassen. Falls es für eine stirnseitige schallentkoppelte Anbindung erforderlich ist, einen Gewindebolzen von grösserem Durchmesser einzuschieben, ist dies wegen der Flexibilität des Wandungsteils innerhalb vorbestimmter Durchmesser leicht möglich.In an advantageous variant of the invention, the cross section of the bore in Foot part essentially in the shape of a three-quarter circle, and the hole is on the side of the foot part facing away from the support part by a flexible wall part edged, which is curved into the bore and can be turned inside out, the opposite side in cross section an essentially circular arc-shaped contour having. Due to the flexible wall part, the hole can be Adjust the need for threaded bolts of different diameters. If it is for a front sound-insulated connection is required, a threaded bolt from Inserting a larger diameter is because of the flexibility of the Part of the wall easily possible within a predetermined diameter.

In einer vorteilhaften Weiterbildung der Erfindung ragen zwei in Längsrichtung verlaufende Vorsprünge von der Wandung in die Bohrung, wobei die Bohrung zur Aufnahme von Bolzen der Durchmesser M6 bis M10 ausgebildet ist.
