Description

Zusatzanmeldung zu Patent 17 84 524 (Patentanmeldung P 17 84 524.8) Schallabsorbierendes und wärmeisolierendes Verbundmaterial als Füllung einer Hohlwand.Additional application to patent 17 84 524 (patent application P 17 84 524.8) Sound-absorbing and heat-insulating composite material as a filling of a cavity wall.

Die Erfindung betrifft ein Schallabsorbierendes und wärmeisolierendes Verbundmaterial aus wechselweise aufeinanderfolgenden gewellten oder -zickzackförmig gefalteten Folien und planen Folien, bei dem wenigstens einige der Folien gleichmässig- perforiert sind, gemäß Patent 17 84 524 (Patentanmeldung P 17 84 524.8).The invention relates to a sound absorbing and heat insulating one Composite material made of alternating corrugated or zigzag shapes folded foils and flat foils, in which at least some of the foils are evenly are perforated, according to patent 17 84 524 (patent application P 17 84 524.8).

Aufgabe der Erfindung ist es, dieses Verbundmaterial zur optimalen Ausnutzung seiner Eigenschaften als Füllung einer Hohlwand, insbesondere in einem Fahrzeug, vorzugsweise einem Eisenbahnwagen zu verwenden.The object of the invention is to optimize this composite material Use of its properties as a filling of a cavity wall, especially in one Vehicle, preferably to use a railroad car.

Die Erfindung geht hierbei von der Feststellung aus, daß die Schallabsorption besonders der Schallwellen erforderlich ist, die sich als stehende Wellen in Richtung der Ebene der Hohlwand ausbilden können, und daß die Schallabsorption des Verbundmaterials besonders hoch fur Schallwellen ist, die sich quer durch die Folien ausbreiten wollen.The invention is based on the finding that the sound absorption is particularly required of the sound waves that are can form as standing waves in the direction of the plane of the cavity wall, and that the sound absorption of the composite material is particularly high for sound waves that want to propagate transversely through the foils.

Dementsprechend lehrt die Erfindung, das Verbundmaterial derart in der Hohlwand anzuordnen, daß die Flächensenkrechten der planen Folien des Verbundmaterials mindestens annähernd parallel zur Ebene der Hohlwand verlaufen. Die Schallabsorption ist dann in Richtung der in der Ebene der Hohlwand verlaufenden Fläctiensenkrechten besonders hoch.Accordingly, the invention teaches the composite material in such a manner to arrange the cavity wall that the surface perpendiculars of the flat sheets of the composite material run at least approximately parallel to the plane of the cavity wall. The sound absorption is then in the direction of the plane perpendicular to the plane of the cavity wall especially high.

Feuchtigkeit, insbesondere Kondenswasser, die sich auf dem Verbundmaterial niederschlägt, soll möglichst gut aus dem Verbundmaterial ablaufen können. Um hierzu in einfacher Weise die Schwerkraft ausnutzen zu können, verlaufen bevorzugt die Scheitel der Wellungen oder Faltungen senkrecht.Moisture, especially condensation, on the composite material If it precipitates, it should be able to drain out of the composite material as well as possible. To do this to be able to utilize gravity in a simple manner, the preferably run Vertices of corrugations or folds perpendicular.

Um eine hohe Schallabsorption in jeder Richtung der Ebene der Hohlwand zu erhalten, wird das Verbundmaterial bevorzugt paketweise in einem Sctiachbrettmuster derart angeordnet, daß die Scheitel der Wellungen oder Faltungen teilweise waagerecht und teilweise senkrecht verlaufen.To have a high level of sound absorption in each direction of the plane of the cavity wall To obtain, the composite material is preferably packaged in a Sctiachbrettmuster arranged in such a way that the vertices of the corrugations or folds are partially horizontal and run partially vertically.

Damit das Verbundmaterial auch unregelmässig geformte Räume in der Hohlwand einigermaßen gleichmässig ausfüllen kann, muß es elastisch sein. Eine besondere Elastizität ergibt sich dann, wenn die planen Folien unperforiert und die gewellten oder zickzackförmig gefalteten Folien perforiert sind.So that the composite material also has irregularly shaped spaces in the Can fill the cavity wall more or less evenly, it must be elastic. A special Elasticity results when the flat foils are imperforate and the corrugated ones or zigzag folded foils are perforated.

Die Schallabsorptionsfähigkeit läuft im wesentlichen parallel zum Strömungswiderstand eines Materials. Bei dem erfindungsgemässen Verbundmaterial ist der Strömungswiderstand in Richtung der von den Wellungen oder Faltungen begrenzten Kanäle in manchen Fällen noch zu gering. Daher wird bevorzugt der Querschnitt der durch die Wellungen oder Faltungen begrenzten Kanäle stellenweise - etwa durch Steppen des Verbundmaterials - verengt.The sound absorption capacity runs essentially parallel to the Flow resistance of a material. In the composite material according to the invention is the flow resistance in the direction limited by the corrugations or folds Channels still too few in some cases. Therefore, the cross section of the is preferred Channels delimited by the corrugations or folds in places - for example by quilting of the composite material - constricted.

Die Erfindung wird im folgenden an Ausführungsbeispielen unter Hinweis auf die beigefügten Zeichnungen beschriben.The invention is illustrated below using exemplary embodiments on the attached drawings.

Fig. 1 zeigt einen Teil eines Pakets eines erfindungsgemässen Verbundmaterials in der Stellung, in der es in einer Hohlwand anzuordnen ist; Fig. 2 zeigt eine schachbrettartige Anordnung von Paketen aus erfindungsgemässe Terbundmaterial.1 shows part of a package of a composite material according to the invention in the position in which it is to be arranged in a cavity wall; Fig. 2 shows a checkerboard type Arrangement of packages made of bundle material according to the invention.

Das Verbundmaterial nach Fig. 1 besteht aus wechselweise aufeinanderfolgenden gewellten Folien 1 und planen Folien 2. Die gewellten Folien weisen gleichmässig verteilt Perforationen 3 auf. Die Flächensenkrechten A der planen Folien 2 verlaufen waagerecht parallel zur Ebene der Hohlwand oder - in anderen Worten - die Scheitel der Wellungen verlaufen senkrecht.The composite material according to Fig. 1 consists of alternately successive corrugated foils 1 and flat foils 2. The corrugated foils are uniform distributes perforations 3. The surface perpendiculars A of the planar foils 2 run horizontally parallel to the plane of the cavity wall or - in other words - the apex the corrugations are perpendicular.

Fig. 2 zeigt Pakete 10 und 11 aus erfindungsgemässem Verbundmaterial, die in einem Schachbrettmuster derart angeordnet sind, daß die Scheitel der Wellungen oder Faltungen teilweise waagerecht und teilweise senkrecht verlaufen. Einzelheiten über das Folienmaterial und dessen Form finden sich in der Patentschrift 17 84 524. Alle diese Einzelheiten können auch für den Zweck des Gegenstands dieser Anmeldung sinnvoll angewendet werden.Fig. 2 shows packages 10 and 11 made of composite material according to the invention, which are arranged in a checkerboard pattern such that the crests of the corrugations or folds are partially horizontal and partially vertical. details About the film material and its shape can be found in patent 17 84 524. All of these details can also be used for the purpose of the subject matter this Registration can be used sensibly.

Aus fertigungstechnischen und verarbeitungstechnischen Gründen liegt die Wellenlänge und die Amplitude der gewellten Folie in der Grössenordnung von 1 cm, vorzugsweise von 0,5 bis 1 cm. 33enachbarte gewellte oder zickzackförmig gewellte Folien verlaufen bevorzugt gleichphasig oder gegenphasig, derart, daß der Strömualgsw widerstand durch das Verbundmaterial in Richtung der Wellungen oder Faltungen unter Berücksichtigung der Perforationen besonders gering wird.For manufacturing and processing reasons the wavelength and the amplitude of the corrugated foil in the order of magnitude of 1 cm, preferably from 0.5 to 1 cm. 33adjacent corrugated or zigzag corrugated Foils preferably run in phase or out of phase, in such a way that the Strömualgsw resistance through the composite material in the direction of the corrugations or folds underneath Consideration of the perforations is particularly low.
