Beschreibung description
Die Erfindung betrifft ein Verbundeiement nach dem Oberbegriff des Patentanspruchs 1. Dieses Verbundelement soll lärm- und wärmedämmend sein und als Boden- oder Wandelement eingesetzt werden können. The invention relates to a composite element according to the preamble of claim 1. This composite element should be noise and heat insulating and can be used as a floor or wall element.
Aus der FR-A 2 195 744 ist ein derartiges Verbundelement bekannt, bei dem ein Kernmaterial ober- und unterseitig mit einer Platte abgedeckt ist, wobei auf die obere Platte ein Bodenbelag aufgeklebt ist. Such a composite element is known from FR-A 2 195 744, in which a core material is covered on the top and bottom with a plate, a floor covering being glued to the top plate.
Das separate Aufkleben eines Belages, einer Schutz- oder Dekorbeschichtung ist ein zusätzlicher Arbeitsschritt bei der Herstellung derartiger Verbundelemente, der abgesehen von der zusätzlichen Kleberschicht in der Platte unwirtschaftlich ist. The separate gluing of a covering, a protective or decorative coating is an additional step in the production of such composite elements, which, apart from the additional adhesive layer in the plate, is uneconomical.
Es wird die Schaffung eines Verbundelementes bezweckt, bei dem der vorerwähnte Nachteil vermieden werden kann. The aim is to create a composite element in which the aforementioned disadvantage can be avoided.
Die erfindungsgemässe Ausbildung des Verbundelementes ergibt sich aus dem kennzeichnenden Teil des Patentanspruchs 1. The inventive design of the composite element results from the characterizing part of patent claim 1.
Im folgenden wird die Erfindung anhand der Abbildung eines Ausführungsbeispiels dargelegt. In the following, the invention is explained on the basis of the illustration of an exemplary embodiment.
Ein Verbundelement besteht aus einem Kernmaterial, das ober- und unterseitig mit einer faserverstärkten Platte 2 und 3 aus einem thermoplastischen Material abgedeckt ist, wobei die obere faserverstärkte Platte 3 aus einem thermoplastischen Material mit einer BeSchichtung 4 versehen ist und die Beschichtung 4 ohne Kleber mit der faserverstärkten Platte 3 verbunden ist. Die nicht mit einer Platte abgedeckten Seiten des Kernmaterials sind mit einer Metallverkleidung 5 abgedeckt. Die Metallverkleidung bildet gewissermassen einen Rahmen, der mit den faserverstärkten Platten 2 und 3 innig verankert ist. Dies wird dadurch erreicht, dass die Metallverkleidung 5 breiter ist als die Dicke des Kernmaterials 1 und in Höhe der faserverstärkten Platten 2 und 3 rechtwinklig abgewinkelt ist, wobei die abgewinkelten Metallflächen auf den ober- und unterseitigen Randzonen des Kernmaterials 1 liegen und von den faserverstärkten Platten 2 und 3 überdeckt und mit diesen verbunden sind. Dieser Verbund wird dadurch verbessert, dass die Metallverkleidung 5 gelocht ist. Eine weitere Verbesserung des Verbundes ist dadurch gegeben, dass die Löcher in der Metallverkleidung 5 Durchreisslöcher sind. A composite element consists of a core material, which is covered on the top and bottom with a fiber-reinforced plate 2 and 3 made of a thermoplastic material, the upper fiber-reinforced plate 3 made of a thermoplastic material being provided with a coating 4 and the coating 4 without adhesive with the fiber-reinforced plate 3 is connected. The sides of the core material that are not covered with a plate are covered with a metal cladding 5. To a certain extent, the metal cladding forms a frame that is firmly anchored to the fiber-reinforced panels 2 and 3. This is achieved in that the metal cladding 5 is wider than the thickness of the core material 1 and is angled at a right angle at the level of the fiber-reinforced plates 2 and 3, the angled metal surfaces lying on the top and bottom edge zones of the core material 1 and from the fiber-reinforced plates 2 and 3 are covered and connected to them. This bond is improved in that the metal cladding 5 is perforated. A further improvement of the bond is given by the fact that the holes in the metal cladding are 5 through holes.
Eine andere Möglichkeit, des innigen Verbundes zwischen den faserverstärkten Platten 2, 3 und der Metallverkleidung 5 besteht darin, dass Platten eingesetzt werden, die grösser sind als die ober- und unterseitige Fläche des Verbundelementes und wenn die überstehenden Flächen der faserverstärkten Platten aus einem thermoplastischen Material während des Herstellungsprozesses in plastischem Zustand in Richtung der Metallverkleidung 5 abgewinkelt und an diese angepresst werden. Another possibility of the intimate bond between the fiber-reinforced panels 2, 3 and the metal cladding 5 is that panels are used that are larger than the top and bottom surface of the composite element and if the protruding surfaces of the fiber-reinforced panels made of a thermoplastic material be angled in the direction of the metal cladding 5 during the manufacturing process and pressed against it.
In beiden Fällen ist die Metallverkleidung 5 ohne zusätzlichen Kleber mit dem übrigen Verbundelement verbunden. In both cases, the metal cladding 5 is connected to the rest of the composite element without additional adhesive.
Das verwendete Kernmaterial 1 ist ein hohlraumreiches Material, bevorzugt ein Schaum oder ein Wabenelement mit beliebiger Wabengeometrie aus The core material 1 used is a void-rich material, preferably a foam or a honeycomb element with any honeycomb geometry
üblichen Werkstoffen vorzugsweise aus Papier, Pappe oder Holz, wobei diese Werkstoffe gegebenenfalls mit Harzen oder sonstigen die Festigkeit und/oder Beständigkeit erhöhenden Mitteln ausgerüstet sein können; es ist aber auch eine Kombination eines Wabenelementes mit Schaum oder einer hohlraumreichen Schüttung möglich. Um die Feuerwiderstandsfähigkeit des erläuterten Verbundelementes zu verbessern ist das Kernmaterial 1 flammwidrig ausgerüstet, entweder dadurch, dass Schaum oder Wabenmaterial aus einem flammfesten Material bestehen, oder dass das Wabenmaterial mit flammwidrigen Substanzen, etwa üblichen Feuerschutzsalzen oder -harzen imprägniert oder beschichtet ist, oder dadurch, dass in den Wabenkammern flammwidriges Material eingeschlossen ist. Die Dicke des Kernmaterials 1 liegt im Bereich von 40 bis 100 mm, bevorzugt im Bereich von 45 bis 55 mm. usual materials preferably made of paper, cardboard or wood, these materials optionally being able to be equipped with resins or other agents which increase the strength and / or resistance; however, a combination of a honeycomb element with foam or a void-rich bed is also possible. In order to improve the fire resistance of the described composite element, the core material 1 is made flame-retardant, either by the fact that foam or honeycomb material consist of a flame-resistant material, or by the honeycomb material being impregnated or coated with flame-retardant substances, for example conventional fire protection salts or resins, or thereby, that flame-retardant material is enclosed in the honeycomb chambers. The thickness of the core material 1 is in the range from 40 to 100 mm, preferably in the range from 45 to 55 mm.
Als faserverstärkte Platte 2, 3 aus thermoplastischem Material sind alle Platten einsetzbar, die aus einem thermoplastischen Kunststoff bestehen der mit Fasergewebe, Faservlies oder mit statistisch in der Kunststoffmatrix verteilte Fasern verstärkt ist. As a fiber-reinforced plate 2, 3 made of thermoplastic material, all plates can be used which consist of a thermoplastic which is reinforced with fiber fabric, fiber fleece or with statistically distributed fibers in the plastic matrix.
Derartige Platten 2, 3 haben eine Dicke von 2 bis 5 mm, bevorzugt von 2, 3 bis 4 mm. Beispiele für thermoplastische Kunststoffe sind Polyolefine wie z.B. Polyethylen, Polypropylen und deren Gemische, ferner Polyvinylverbindungen sowie Copoly-merisate wie ABS oder SAN, Polyamide, Polyaceta-le, Polycarbonate oder Polyester. Beispiele für Fasermaterial sind Cellulose, Kohlenstoff-, Kunststoff-, Glas-, Mineral- oder Keramikfasern. Such plates 2, 3 have a thickness of 2 to 5 mm, preferably of 2, 3 to 4 mm. Examples of thermoplastics are polyolefins such as e.g. Polyethylene, polypropylene and their mixtures, also polyvinyl compounds and copolymers such as ABS or SAN, polyamides, polyacetals, polycarbonates or polyesters. Examples of fiber material are cellulose, carbon, plastic, glass, mineral or ceramic fibers.
Bevorzugt verwendet werden glasfaserverstärkte Platten 2, 3 aus Polyolefinen, insbesondere aus Polypropylen. Derartige Platten sind als sogenannte GMT-Platten im Handel. Glass fiber reinforced sheets 2, 3 made of polyolefins, in particular made of polypropylene, are preferably used. Such plates are commercially available as so-called GMT plates.
Die Beschichtung 4 ist ohne Kleber mit der faserverstärkten Platte 3 verbunden, d.h. sie ist direkt mit der Matrix des Thermoplasten verankert. Daher sind als Beschichtung 4 alle Materialien geeignet, deren dem Kunststoff zugeneigte Seite nicht glatt ist, die somit eine mechanische Verankerung in der thermoplastischen Kunststoffmatrix ermöglichen. Beispiele hierfür sind Gewebe, Holz, Kork, Filz oder mineralische Materialien, insbesondere Fliesen oder Mineralgranulat. Als Beschichtung 4 einsetzbar sind aber auch Verbundwerkstoffe, die eine poröse oder rauhe Fläche besitzen wie z.B. Linoleum oder Kunststeinplatten mit einer Unterseite aus Mineralgranulat oder Blähton. The coating 4 is connected to the fiber-reinforced plate 3 without adhesive, i.e. it is anchored directly to the matrix of the thermoplastic. Therefore, all materials are suitable as coating 4, the side of which is inclined toward the plastic is not smooth, and which thus enable mechanical anchoring in the thermoplastic plastic matrix. Examples of this are fabrics, wood, cork, felt or mineral materials, in particular tiles or mineral granulate. Composite materials which have a porous or rough surface, such as e.g. Linoleum or artificial stone slabs with a mineral granulate or expanded clay underside.
Die erläuterten Verbundelemente können beliebige äussere Abmessungen haben. Bevorzugte Abmessungen sind 60 x 60 cm bzw. 60 x 120 cm. The composite elements explained can have any external dimensions. Preferred dimensions are 60 x 60 cm or 60 x 120 cm.
