Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Vibrations- und Schalldämpfung von an Betonfundamenten befestigten Schienen für Züge, insbesondere Hochgeschwindigkeitszüge, bestehend aus einem Formteil aus Kunststoff, welches als Zwischenlage oder Zwischenplatte zwischen der Schiene und dem Fundament angeordnet ist.The The invention relates to a device for vibration and sound attenuation of Rails attached to concrete foundations for trains, in particular high-speed trains, consisting from a molded part made of plastic, which as an intermediate layer or Intermediate plate between the rail and the foundation arranged is.
Solche Formteile aus Kunststoff sind im Stand der Technik bekannt. Sie dienen als elastische Zwischenlagen oder Zwischenplatten mit einer definierten statischen Nennfestigkeit. Die Zwischenlagen oder Zwischenplatten werden zwischen der Schiene und dem Betonfundament platziert, wobei die Schienen in üblicher Weise mit Klemmeinrichtungen am Fundament befestigt werden. Der Einsatz solcher Zwischenlagen erfolgt in unterschiedlichen Geschwindigkeitsbereichen und Fahrbahnausführungen, wobei differenzierte technische Anforderungen erfüllt werden müssen, denen durch entsprechende Materialauswahl nachgekommen wird. Bei den bisher üblichen Formteilen dieser Art aus Kunststoff besteht das Formteil beispielsweise aus hochfestem Schaum, wodurch die entsprechende Schalldämpfung und Vibrationsdämpfung erreicht werden soll. Solche Elemente sind aber hinsichtlich ihrer Alterungs- und Witterungsbeständigkeit unbefriedigend. Auch die Einstellung der Qualität der Zwischenplatte an bestimmte technische Anforderungen ist schwierig zu erfüllen.Such Plastic moldings are known in the art. she serve as elastic intermediate layers or intermediate plates with a defined static nominal strength. The liners or intermediate plates are placed between the rail and the concrete foundation, with the Rails in usual Way be secured with clamps on the foundation. Of the Use of such intermediate layers takes place in different speed ranges and roadway designs, whereby differentiated technical requirements are fulfilled have to, which is followed by appropriate material selection. at the usual Moldings of this type made of plastic, the molding, for example made of high-strength foam, giving the appropriate soundproofing and vibration damping should be achieved. But such elements are in terms of their Aging and weathering resistance unsatisfactory. Also, the setting of the quality of the intermediate plate to certain technical requirements is difficult to meet.
Hiervon ausgehend liegt der Erfindung zugrunde, eine Vorrichtung gattungsgemäßer Art zu schaffen, bei der in einfacher Art und Weise eine vorzügliche Anpassung des Formteiles an unterschiedliche technische Anforderungen erreicht wird, wobei einerseits eine gute Vibrations- und Schalldämpfung, andererseits aber auch eine hohe Alterungs- und Witterungsbeständigkeit erreicht wird.Of these, Based on the invention, a device of the generic type to create, in a simple way, an excellent adaptation achieved the molding to different technical requirements is on the one hand a good vibration and sound attenuation, on the other hand but also a high resistance to aging and weathering is achieved.
Zur Lösung dieser Aufgabe wird vorgeschlagen, dass das Formteil einen Kern aus elastischem Material aufweist, der von einem Mantel aus formstabilen Material umgeben ist.to solution This object is proposed that the molding a core made of elastic material which is dimensionally stable from a jacket Material is surrounded.
Gemäß der Erfindung ist das beispielsweise im Wege eines 2-Komponenten-Spritzgießverfahrens oder eines 2-Komponenten-Monosandwichverfahrens hergestellte Formteil mit einem inneren Kern aus hochelastischem Material versehen, wodurch die gewünschte Vibrations- und Schalldämpfung realisiert werden kann. Dieser Kern ist von einem Mantel aus formstabilem Material, insbesondere Kunststoffmaterial, umgeben. Dieses Material kann glattflächig und geschlossenporig ausgebildet sein, so dass es hohe Resistenz gegen Verschmutzung und Fremdstoffe wie Öl und Wasser aufweist. Darüber hinaus ist dieses Material vorzugsweise sehr alterungs- und witterungsbeständig. Durch entsprechende Auswahl von Materialien kann die Qualität des Formteiles unterschiedlich entsprechend den gewünschten Anforderungen eingestellt werden.According to the invention This is for example by way of a 2-component injection molding process or a 2-component monosandwich process molded part provided with an inner core of highly elastic material, whereby the desired Vibration and soundproofing can be realized. This core is made of a shell of dimensionally stable Material, in particular plastic material, surrounded. This material can be smooth and smooth be formed closed pore, so that it is highly resistant to Pollution and foreign substances such as oil and water. Furthermore this material is preferably very resistant to aging and weathering. By Appropriate selection of materials can improve the quality of the molded part set differently according to the desired requirements become.
Bevorzugt ist zudem vorgesehen, dass der Kern aus hochelastischem Kunststoff besteht.Prefers is also provided that the core of highly elastic plastic consists.
Besonders bevorzugt ist, dass der Kern aus einer vorzugsweise hochelastischen Schaumstruktur aus geschäumtem Kunststoff besteht.Especially preferred is that the core of a preferably highly elastic Foam structure of foamed Plastic exists.
Auch kann vorgesehen sein, dass das Formteil im Querschnitt etwa U-förmig ist.Also can be provided that the molding is approximately U-shaped in cross section.
Dabei ist bevorzugt vorgesehen, dass der Kern U-förmig ist und vollständig von dem Mantel umhüllt ist.there is preferably provided that the core is U-shaped and completely from wrapped in the coat is.
Besonders bevorzugt ist vorgesehen, dass der Mantel aus lichtbeständigem, alterungsbeständigem und witterungsbeständigem Kunststoff besteht.Especially Preferably, it is provided that the sheath of light-resistant, non-aging and weatherproof Plastic exists.
Eine alternative preiswerte Vorrichtung ist im Anspruch 7 angegeben.A Alternative inexpensive device is specified in claim 7.
Solche Zwischenplatten können beispielsweise im Normalbetrieb von Zügen eingesetzt werden, wobei zur Kostenersparnis ein preiswerter Kern von einem hochwertigen Mantel aus Kunststoff umgeben ist.Such Intermediate plates can be used for example in the normal operation of trains, wherein for cost savings a cheap core of a high quality Sheath is surrounded by plastic.
