Description
<Desc/Clms Page number 1>
Die Erfindung betrifft ein Verbundelement, insbesondere zur Verkleidung von Wänden, Decken,
Böden u. dgl. mit einer Schalldämmungslage aus Blech, die zu beiden Seiten eine Schaumstoffschicht aufweist. Das erfindungsgemässe Verbundelement soll auch zur Verkleidung von Rohren geeignet sein.
Es sind verschiedene Schallschutzisolierungen bekannt, die in der Regel aus Schaumstoff- schichten und/oder Vliesschichten bestehen und ihren Zweck mehr oder weniger befriedigend er- füllen.
Ziel der Erfindung ist die Schaffung eines Verbundelements, mit dem eine optimale Schall- schutzwirkung erzielt wird. Dieses Ziel wird mit einem Verbundelement der eingangs genannten
Art erreicht, bei dem erfindungsgemäss die Schaumstoffschichten, wie an sich bekannt, offene Poren aufweisen und eine Schaumstoffschicht eine vorzugsweise luftdurchlässige Vliesschicht trägt, wobei die Blechschicht aus einem Tiefziehblech besteht und vorzugsweise mittels Kleber mit den Schaum- stoffschichten verbunden ist.
Vorzugsweise enthält das Verbundelement als Vliesschicht eine genadelte Vliesschicht aus Polyesterfilament, die vorzugsweise binderverfestigt ist.
Bevorzugt besteht die Schaumstoffschicht, die das Vlies trägt, aus demselben Material wie die andere Schaumstoffschicht, wobei das Material vorzugsweise ein Polyesterschaum ist.
Erfindungsgemäss kommt als Schalldämmungslage insbesondere ein Tiefziehblech aus Aluminium in Frage.
Nach einer besonderen Ausführungsform der Erfindung ist die Schalldämmungslage gegenüber den Rändern der übrigen Schichten zurückversetzt, vorzugsweise im Ausmass von 2 bis 3 mm. Durch diese Massnahme soll erreicht werden, dass die Schalldämmungslage, also der schwingende Absorber, frei schwingen kann.
Durch die erfindungsgemässe Kombination der schalldämpfenden Schaumstoffschicht/Vliesschicht und der schalldämmenden Lage aus Tiefziehblech mit der anschliessenden Schicht aus Schaumstoff wird eine hervorragende Schallschutzisolation erreicht. In einer beispielsweisen und bevorzugten Ausführungsform der Erfindung besteht das Verbundelement aus einem schallschluckenden Absorber aus einer genadelten luftdurchlässigen binderverfestigten Vliesschicht aus Polyesterfilament mit einer damit verbundenen offene Poren aufweisenden Schaumstoffschicht aus weichem Polyesterschaumstoff mit vorzugsweise 40% offenen Poren und einer Dicke von 5 mm, einem tiefziehfähigen Stahlblech mit einer Dicke von 1 mm und einer offenzelligen Schaumstoffschicht mit einer Dicke von 5 mm.
In dem erfindungsgemässen Verbundelement kann die Unterlagsschicht aus Schaumstoff auch wesentlich dicker, beispielsweise bis zu 3 cm dick sein.
In einem erfindungsgemässen Verbundelement kann der mitschwingende Absorber als Schalldämmungslage aus z. B. Stahlblech und damit verbundener Unterlagsschicht aus Schaumstoff einoder mehrfach angeordnet sein. Hiebei können die Schalldämmungslagen aus Tiefziehblech unterschiedliche Massen aufweisen, was die Erzielung unterschiedlicher Durchgangsdämmungen erlaubt.
Die eingesetzten Schaumstoffe sollen schwer entflammbar und nicht qualmend ausgerüstet sein.
Das erfindungsgemässe Verbundelement kann nach Mass in Platten vorproduziert werden. Beim Verlegen der Platten z. B. auf den Wänden stellt die Vliesschicht die dem Raum zugewandte Schicht dar. Diese Schicht soll daher tapezierbar sein. Die Verlegung an den Wänden erfolgt vorzugsweise mittels Kontakt- oder Dispersionskleber. Das luftdichte Verbinden der Stösse der Platten erfolgt
EMI1.1
Um eine Distanzierung der Verbundelemente an Boden, Decken und Wänden zu gewährleisten, können Gummipuffer, beispielsweise mit einer Stärke von 2 bis 3 mm, auf das Verbundelement aufgeschoben oder geklebt werden. Die Anschlüsse können mit Silikon geschlossen werden.
Erfindungsgemäss sind die Schaumstoffschicht und die weitere Schicht aus Schaumstoff mit der Schalldämmungslage aus Tiefziehblech mittels eines 2-Komponentenklebers mit Rostschutzwirkung verbunden.
Das erfindungsgemässe Verbundelement kann nicht nur in Platten, sondern auch als Teilschalen zum Verkleiden von z. B. Rohren vorproduziert sein. In diesem Fall besteht es vorzugsweise aus einer geschlossenporigen Schaumstoffschicht, einer damit verbundenen Schalldämmungs-
<Desc/Clms Page number 2>
lage aus Stahl- oder Aluminiumblech sowie einer mit letzterer weiters verbundenen Unterlagsschicht aus Schaumstoff. Indem die Aussenschicht eine geschlossenporige Schicht, z. B. eine PVC-Schicht ist, wird der Zutritt von Wasser, z. B. aus Verputz- oder Betonschichten, zur Schalldämmungslage aus Stahl- oder Aluminiumblech verhindert. Das erfindungsgemässe Verbundelement kann z.
B. als zusätzliche Schalldurchgangsdämmung für Aussen- und Zwischenmauern sowie Lüftungs- und Kühlkanälen, als Schalldämmung an Karosseriebestandteilen und Abwasserleitungen verwendet werden.
In der Zeichnung ist ein Querschnitt durch ein erfindungsgemässes als Platte ausgeführtes Verbundelement beispielsweise dargestellt.
Gemäss der Zeichnung besteht das Verbundelement aus einer genadelten, binderverfestigten
EMI2.1
Polyesterschaum verbunden. An diese Schaumstoffschicht ist ein etwa 1 mm dickes tiefziehfähiges Stahlblech --3-- mit einem 2-Komponentenkleber mit Rostschutzwirkung geklebt. Mit dem Stahlblech --3-- ist weiters eine Schaumstoffschicht --4-- analog der Schaumstoffschicht --2-- unter Verwendung des bereits genannten Klebers verbunden.
PATENTANSPRÜCHE :
1. Verbundelement, insbesondere zur Verkleidung von Wänden, Decken, Böden u. dgl. mit einer Schalldämmungslage aus Blech, die zu beiden Seiten eine Schaumstoffschicht aufweist, dadurch gekennzeichnet, dass die Schaumstoffschichten, wie an sich bekannt, offene Poren aufweisen und eine Schaumstoffschicht eine vorzugsweise luftdurchlässige Vliesschicht trägt, wobei die Blechschicht aus einem Tiefziehblech besteht und vorzugsweise mittels Kleber mit den Schaumstoffschichten verbunden ist.

The invention relates to a composite element, in particular for cladding walls, ceilings,
Floors and Like. With a sound insulation layer made of sheet metal, which has a foam layer on both sides. The composite element according to the invention should also be suitable for cladding pipes.
Various soundproofing insulations are known which generally consist of foam layers and / or nonwoven layers and fulfill their purpose more or less satisfactorily.
The aim of the invention is to create a composite element with which an optimal sound insulation effect is achieved. This goal is achieved with a composite element of the aforementioned
Type achieved in which, according to the invention, the foam layers, as is known per se, have open pores and a foam layer carries a preferably air-permeable nonwoven layer, the sheet metal layer consisting of a deep-drawn sheet and preferably connected to the foam layers by means of adhesive.
The composite element preferably contains as a nonwoven layer a needled nonwoven layer made of polyester filament, which is preferably bond-bonded.
The foam layer which carries the fleece preferably consists of the same material as the other foam layer, the material preferably being a polyester foam.
According to the invention, a deep-drawn sheet made of aluminum is particularly suitable as a sound insulation layer.
According to a special embodiment of the invention, the soundproofing layer is set back with respect to the edges of the other layers, preferably to an extent of 2 to 3 mm. This measure is intended to ensure that the soundproofing layer, i.e. the vibrating absorber, can vibrate freely.
The inventive combination of the sound-absorbing foam layer / fleece layer and the sound-absorbing layer made of deep-drawn sheet metal with the adjoining layer of foam achieves excellent sound insulation. In an exemplary and preferred embodiment of the invention, the composite element consists of a sound-absorbing absorber made of a needled air-permeable, binder-bonded nonwoven layer made of polyester filament with an associated open-pore foam layer made of soft polyester foam with preferably 40% open pores and a thickness of 5 mm, a deep-drawable steel sheet with a thickness of 1 mm and an open-cell foam layer with a thickness of 5 mm.
In the composite element according to the invention, the underlay layer made of foam can also be considerably thicker, for example up to 3 cm thick.
In a composite element according to the invention, the resonating absorber can be made of z. B. steel sheet and associated backing layer made of foam one or more times. The soundproofing layers made of deep-drawn sheet metal can have different masses, which allows different types of passage insulation to be achieved.
The foams used are said to be flame-retardant and non-smoking.
The composite element according to the invention can be pre-produced to size in plates. When laying the plates z. B. on the walls, the fleece layer represents the layer facing the room. This layer should therefore be papered. Laying on the walls is preferably done using contact or dispersion adhesive. The airtight connection of the joints of the panels takes place
EMI1.1
To ensure spacing of the composite elements on the floor, ceiling and walls, rubber buffers, for example with a thickness of 2 to 3 mm, can be pushed or glued onto the composite element. The connections can be closed with silicone.
According to the invention, the foam layer and the further layer made of foam are connected to the soundproofing layer made from deep-drawn sheet metal by means of a two-component adhesive with rust protection effect.
The composite element according to the invention can be used not only in plates, but also as partial shells for cladding z. B. pipes are pre-produced. In this case, it preferably consists of a closed-pore foam layer, an associated sound insulation
<Desc / Clms Page number 2>
layer of sheet steel or aluminum and a base layer of foam connected to the latter. By the outer layer a closed-pore layer, e.g. B. is a PVC layer, the access of water, for. B. from plaster or concrete layers, to the soundproofing layer of steel or aluminum sheet prevented. The composite element according to the invention can, for.
B. be used as additional sound insulation for outer and intermediate walls and ventilation and cooling channels, as sound insulation on body components and sewage pipes.
In the drawing, a cross section through an inventive composite element designed as a plate is shown, for example.
According to the drawing, the composite element consists of a needled, binder-consolidated
EMI2.1
Polyester foam connected. An approximately 1 mm thick deep-drawn steel sheet --3-- is glued to this foam layer with a 2-component adhesive with rust protection effect. The steel sheet --3-- is also connected to a foam layer --4-- analogous to the foam layer --2-- using the adhesive already mentioned.
