Description
Die Erfindung bezieht sich auf ein mit Perforationen versehenes schallabsorbierendes und wärmeisolierendes Verbundmaterial aus wechselweise aufeinanderfolgenden planen und gefalteten Folien, bei dem entweder nur die gefalteten Folien oder nur die planen Folien perforiert sind, nach Patent 17 84 524, als Füllung einer Hohlwand, insbesondere in einem Fahrzeug, vorzugsweise in einem Eisenbahnwagen.The invention relates to a perforated sound-absorbing and heat-insulating one Composite material made of alternately successive flat and folded foils, in which either only the folded foils or only the flat foils are perforated, according to patent 17 84 524, as a filling of a Cavity wall, in particular in a vehicle, preferably in a railroad car.
Der Erfindung liegt die Aufgabe zugrunde, das im Hauptpatent 17 84 524 vorgeschlagene Verbundmaterial so zu gestalten, daß eine optimale Ausnutzung seiner Eigenschaften als Füllung einer Hohlwand, insbesondere in einem Fahrzeug, vorzugsweise einem Eisenbahnwagen, erreicht ist.The invention is based on the object of the composite material proposed in the main patent 17 84 524 to be designed in such a way that an optimal use of its properties as a filling of a cavity wall, is achieved in particular in a vehicle, preferably 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 für Schallwellen ist, die sich quer durch die Folien ausbreiten wollen.The invention is based on the finding that the sound absorption especially of the sound waves is required, which 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 travel across the foils want to spread.
Die der Erfindung zugrundeliegende Aufgabe wird erfindungsgemäß dadurch gelöst, daß die planen Folien des Verbundmaterials etwa senkrecht zur Ebene der Hohlwand verlaufen. Bei der erfindungsgemäßen Ausgestaltung des Verbundmaterials ist die Schallabsorption in Richtung der in der Ebene der Hohlwand verlaufenden Flächensenkrechten besonders hoch. Unter gefalteten Folien können bei dem erfindungsgemäßen Verbundmaterial sowohl zickzackförmig gefaltete Folien als auch gewellte Folien verstanden werden.The object on which the invention is based is achieved according to the invention in that the planar foils of the composite material run approximately perpendicular to the plane of the cavity wall. In the inventive The design of the composite material is the sound absorption in the direction of the plane of the cavity wall running surface perpendiculars particularly high. Under folded films can in the invention Composite material both zigzag folded foils and corrugated foils are understood.
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, ist es günstig, wenn die Scheitel der Faltungen der gefalteten Folien senkrecht in der Hohlwand angeordnet sind.Moisture, in particular condensation, which is deposited on the composite material, should if possible can drain well out of the composite material. In order to use gravity for this purpose in a simple manner it is advantageous if the vertices of the folds of the folded foils are perpendicular in the cavity wall are arranged.
Um eine hohe Schallabsorption in jeder Richtung der Ebene der Hohlwand zu erhalten, wird das Verbundmaterial bevorzugt paketweise in einem Schachbrettmuster derart angeordnet, daß die Scheitel der Faltungen wechselweise senkrecht und v-aagrecht verlaufen.In order to obtain a high level of sound absorption in each direction of the plane of the cavity wall, the composite material is used preferably arranged in packets in a checkerboard pattern in such a way that the vertices of the folds run alternately vertically and horizontally.
Damit das Verbundmaterial auch unregelmäßig geformte Räume in der Hohlwand etwa gleichmäßig ausfüllen kann, muß es elastisch sein. Eine besondere Elastizität ergibt sich dann, wenn nur die gefalteten Folien Perforationen aufweisen.So that the composite material also irregularly shaped spaces in the cavity wall approximately evenly can fill out, it must be elastic. A special elasticity results when only the folded Foil have perforations.
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 ist es günstiger, das erfindungsgemäße Verbundmaterial so auszubilden, daß der Querschnitt der durch die Faltungen begrenzten Kanäle stellenweise, z. B. durch Steppen des Verbundmaterials, verengt ist.The sound absorption capacity runs essentially parallel to the flow resistance of a material. at the composite material according to the invention is the flow resistance in the direction of the corrugations or folds delimited channels in some cases still too few. Therefore, it is cheaper to do that to form composite material according to the invention so that the cross section of the limited by the folds Channels in places, e.g. B. is narrowed by quilting the composite material.
Die Erfindung wird im folgenden anhand von Ausführungsbeispielen in Verbindung mit der Zeichnung beschrieben. Es zeigtThe invention is illustrated below with the aid of exemplary embodiments in conjunction with the drawing described. It shows
F i g. 1 einen Teil eines Pakets eines erfindungsgemäßen Verbundmaterials in der Stellung, in der es in einer Hohlwand anzuordnen ist;F i g. 1 shows part of a package of a composite material according to the invention in the position in which it is in a Cavity wall is to be arranged;
F i g. 2 eine schachbrettartige Anordnung von Paketen aus dem eriindungsgemäßen Verbundmaterial.F i g. 2 shows a checkerboard arrangement of packages made from the composite material according to the invention.
Das Verbundmaterial nach F i g. 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 waagrecht 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 have perforations 3 distributed evenly. The surface perpendiculars A of the planar foils 2 run horizontally parallel to the plane of the cavity wall or - in other words - the vertices of the corrugations run perpendicular.
F i g. 2 zeigt Pakete 10 und 11 aus dem erfindungsgemäßen Verbundmaterial, die in einem Schachbrettmuster derart angeordnet sind, daß die Scheitel der Wellungen oder Faltungen teilweise waagrecht und teilweise senkrecht verlaufen.F i g. 2 shows packages 10 and 11 from the invention Composite material arranged in a checkerboard pattern so that the vertices of the Corrugations or folds are partially horizontal and partially vertical.
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. Benachbarte gewellte oder zickzackförmig gefaltete Folien verlaufen bevorzugt gleichphasig oder gegenphasig, derart, daß der Strömungswiderstand 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 are of the corrugated film in the order of 1 cm, preferably from 0.5 to 1 cm. Neighboring corrugated or zigzag folded foils run preferably in phase or out of phase, such that the Flow resistance through the composite material in the direction of the corrugations or folds under consideration the perforations is particularly small.
