Abstract
Description
Die Erfindung betrifft eine Bahnschwelle mit unterseitiger Beschichtung bzw. Besohlung mittels einer Verbundplatte.The invention relates to a railway sleeper with underside coating or soles by means of a composite plate.
Bei bekannten Bahnschwellen aus Spannbeton, Beton oder Stahl sind unterseitige Beschichtungen bekannt (Besohlung), mit denen die schotterschonenden Eigenschaften einer Holzschwelle nachempfunden werden.In known railway sleepers made of prestressed concrete, concrete or steel underside coatings are known (soles), with which the ballast-friendly properties of a wooden sill are modeled.
Bei diesen sogenannten Schwellenbesohlungen werden unterseitige Beschichtungen aus elastischen Materialien im Fertigungsverfahren beim Betonieren aufgelegt oder nachträglich an den Unterseiten von Bahnschwellen aufgeklebt.In these so-called threshold solders, underside coatings of elastic materials are applied in the manufacturing process during concreting or adhesively bonded to the underside of railway sleepers.
Bei elastischen Besohlungen wird in bekannten Verfahren eine elastische Kunststoff- oder Gummischicht bereits bei der Herstellung mit einer Splittstreuung beschichtet, die eine Verbindung zum Beton bei der Herstellung von Betonschwellen ermöglicht. Andere Verfahren bevorzugen eine Profilierung in der Besohlung mit betonhaftenden Eigenschaften.In elastic soles, in known processes, an elastic plastic or rubber layer is already coated during production with a grit spread, which allows a connection to the concrete in the production of concrete sleepers. Other methods prefer profiling in the decking with concrete-adhering properties.
Es ist bekannt, die elastische Kunststoffschicht direkt mit dem Betonkörper zu verbinden (
Die bei festen Fahrbahnen zur Anwendung kommenden, die Schwelle teilweise umschließenden elastischen Profile (sogenannte beschuhte Schwellen) sind nicht mit besohlten Schwellen im Sinne dieser Erfindung identisch.The on solid lanes coming to the application, the threshold partially enclosing elastic profiles (so-called shrouded sleepers) are not identical with soled thresholds in the context of this invention.
Bei allen Materialien von unterseitigen Schwellenbeschichtungen ist eine Oberflächenfestigkeit der Materialien erforderlich, die ein Eindringen der Schotterspitzen in diese Besohlung ausschließt.All materials of bottom side tie coatings require a surface strength of the materials which precludes penetration of the ballast points into that sole.
Die Elastizität der Materialien, die Festigkeit gegen Spitzendruck des Schotters, die Möglichkeit der Haftung gegen Beton und die Betriebsfestigkeit des Systems stehen hierbei im gegenseitigen Widerspruch und schränken die Dauerhaftigkeit bzw. die Funktionalität ein.The elasticity of the materials, the resistance to top pressure of the ballast, the possibility of adhesion to concrete and the durability of the system are in conflict with each other and limit the durability and functionality.
Materialkombinationen, bei denen in Sandwichbauweise verschiedene Lagen unterschiedlicher Materialien laminiert und aufeinandergefügt werden, sind derart aufwändig, dass der Einsatz aus Kostengründen in Frage gestellt ist.Material combinations in which different layers of different materials are laminated and stacked in sandwich construction, are so complex that the use is questioned for cost reasons.
Der Nachteil bekannter Systeme besteht darin, dass:
- bei diesen elastischen Besohlungen das schwingungstechnische Verhalten bei Verwendung einer ebenfalls elastischen Schienenbefestigung durch Eigenschwingungen der Schwelle schwer definierbar ist und Eigenschwingungen der Betonschwelle möglich sind, die das System schädigen.
- die bei elastischen Besohlungen geforderten Steifigkeiten derart weiche Materialien erfordern, dass eine Resistenz gegen Schäden durch Schotterkanten und Schotterspitzen nicht ausgeschlossen werden kann.
- die Herstellung und Applikation von anforderungsgerechten Sohlen derart kostenintensiv ist, dass der Einsatz elastischer Schienenbefestigungen ggf. vorteilhafter sein kann.
- in these elastic Besohlenungen the vibration behavior when using a likewise elastic rail fastening by natural vibration of the threshold is difficult to define and natural vibrations of the concrete sleeper are possible, which damage the system.
- the stiffnesses required for elastic fillings require such soft materials that resistance to damage from ballast edges and ballast points can not be ruled out.
- the production and application of soles according to requirements is so costly that the use of elastic rail fasteners may possibly be more advantageous.
Eine Aufgabe der Erfindung ist es, ein verfahren zur scherkraftfesten Verbindung eines Bahnschwellen-Betonkörpers mit mindestens einer unterseitig des Betonkörpers angeordneten elastischen Kunsstoffschicht mit einem Schotterbett zu schaffen, deren Besohlung fertigungstechnisch einfach realisiert und dauerhaft elastisch angebracht werden kann.An object of the invention is to provide a method for shear force-resistant connection of a railway sleeper concrete body with at least one underside of the concrete body arranged elastic Kunsstoffschicht with a ballast bed, the soloing of which can be easily realized manufacturing technology and permanently elastic.
Mit der Erfindung wird eine Verfahren vorgeschlagen, wie sie im Anspruch 1 angegeben ist.With the invention, a method is proposed, as indicated in claim 1.
Erfindungsgemäß wird die Konstruktion, Fertigung und Applikation von Schwellenbesohlungen unter Ausschluss vorgenannter Nachteile dadurch gelöst, dass die Schwellensohle aus einer mehrlagigen Konstruktion unter Verwendung eines vernadelten Wirrfaser-Vliesmaterials und insbesondere eines Geotextils und mindestens einer elastischen Kunststoffschicht mit definierten Eigenschaften besteht.According to the invention, the design, manufacture and application of threshold solders, excluding the aforementioned disadvantages, is achieved in that the sleeper sole consists of a multi-layered construction using a needled nonwoven fiber material and in particular a geotextile and at least one elastic plastic layer with defined properties.
Vliesmaterialien und insbesondere Geotextilien besitzen überraschenderweise hervorragende Haftungseigenschaften gegenüber Frischbeton und zugleich plastische und elastische Eigenschaften. Durch Wahl der Faserstrukturen, Faserdichte, Faserverbindung (Vernadelung) und Lagendicke kann diese Eigenschaft den Anforderungen angepasst werden.Nonwoven materials and in particular geotextiles surprisingly have excellent adhesion properties to fresh concrete and at the same time plastic and elastic properties. By choosing the fiber structures, fiber density, fiber connection (needling) and layer thickness, this property can be adapted to the requirements.
Die Fasern eignen sich andererseits zur thermischen Verbindung mit elastischen Kunststoffen. Diese Kunststoffe können wiederum in Oberflächenhärte, Elastizität und Stärke den Anforderungen der Schwellenbesohlung angepasst werden.On the other hand, the fibers are suitable for thermal bonding with elastic plastics. These plastics, in turn, can be adapted in surface hardness, elasticity and strength to the requirements of the threshold soling.
Die mit der Erfindung erzielten Vorteile sind verblüffend und haben sich in mehreren Prüfstand- und Langzeitversuchen bewährt. Diese sehr positiven Versuchsergebnisse sind auf die neuartige Verbindung der elastischen Kunststoffschicht mit dem Betonkörper zurückzuführen, die auch als "Mikroformschluss" bezeichnet werden kann. Dieser Mikroformschluss, das heißt die Ankopplung bzw. mechanische Verbindung der mindestens einen elastischen Kunststoffschicht oder bei mehreren elastischen Kunststoffschichten der Sandwich-Aufbau dieser Schichten an bzw. mit dem Betonkörper durch die Fasern der Vliesschicht, führt zu extrem hohen Abreiß- und Scherfestigkeiten, die für den dauerhaften Halt der elastischen Kunststoffschicht an der Unterseite des Betonkörpers sorgen, und zwar auch bei den für Bahnschwellen typischen dynamischen Belastungen. Die Vliesschicht sorgt dabei für eine kraftschlüssige Materialpaarung zwischen Beton und Kunststoff. Durch den Mikroformschluss entlang der genannten Fläche der Vliesschicht erhöht sich ganz entscheidend die Abrissfestigkeit der Kunststoffplatte von dem Betonkörper, was darauf zurückzuführen ist, dass aufgrund der Vliesschicht die Verbindung zwischen Kunststoffplatte und Beton unsensibel gegenüber Scherkräften und Vibrationen ist, da sozusagen eine flexible Anbindung der Kunststoffplatte an der Schwelle gegeben ist. Während herstellungsbedingt das Geotextil mit dem Kunststoffmaterial der Platte verschweißt ist bzw. zumindest die Faserenden des Vlieses in dem Material der Kunststoffplatte eingebettet sind, dringt der Beton beim Gießen der Schwelle teilweise in die Vliesschicht ein, so dass es nach Aushärtung des Betons zu einer mechanischen Verhakung der Fasern in der oberflächennahen Betonschicht kommt. Statt eines Geotextils kann auch ein anderes (Kunststoff-) Wirrfaser-Vliesmaterial eingesetzt werden.The advantages achieved by the invention are astonishing and have proven themselves in several test bench and long-term tests. These very positive test results are due to the novel compound of the elastic plastic layer with the concrete body, which can also be referred to as "microforming". This microforming, that is the coupling or mechanical connection of the at least one elastic plastic layer or in the case of several elastic plastic layers of the sandwich structure of these layers on or with the concrete body by the fibers of the nonwoven layer, leads to extremely high tear and shear strengths, which ensure the lasting hold of the elastic plastic layer on the underside of the concrete body, even with the dynamic loads typical of railway sleepers. The fleece layer ensures a frictional material pairing between concrete and plastic. Due to the microforming connection along said surface of the nonwoven layer, the demolition resistance of the plastic plate of the concrete body increases decisively, which is due to the fact that due to the nonwoven layer, the connection between the plastic plate and concrete is insensitive to shear forces and vibrations, as it were a flexible connection of the plastic plate is given on the threshold. While production reasons, the geotextile is welded to the plastic material of the plate or at least the fiber ends of the web are embedded in the material of the plastic plate, the concrete penetrates during casting of the threshold partially in the nonwoven layer, so that it after curing of the concrete to a mechanical entanglement the fibers come in the near-surface concrete layer. Instead of a geotextile, another (plastic) random fiber nonwoven material can be used.
Die Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.The invention will be explained in more detail with reference to the drawing.

Die Sohle 10 besteht z.B. aus einer 3 mm bis 5 mm starken elastischen Kunststoffschicht 14 mit einer definierten Federkennziffer von z.B. 200 kN/mm. Beim Austritt der Kunststofflage aus dem Extruder wird im noch thermisch bedingt plastischen Zustand eine Kunststoff-Vliesschicht, z. B. eine Geotextilschicht 16 auf die Kunststoffschicht 14 aufgelegt und mit dieser fertigungsintern unter Ausnutzung der noch nicht erhärteten Konsistenz des Kunststoffs verschweißt. Statt einer einlagigen Kunststoffschicht 14 kann diese auch mehrlagig ausgebildet sein. Die Verschweißung der Fasern der Geotextilschicht 16 mit der Kunststoffschicht 14 sowie die Einbettung der Fasern in der Betonschwelle 12 sind in der schematischen Zeichnung nicht dargestellt.The sole 10 consists e.g. from a 3 mm to 5 mm thick elastic

The thickness of the geotextile layer is about 3 mm to 10 mm. When installed, the

Bei der Bahnschwelle kann es sich um eine Spannbeton-Bahnschwelle oder um eine schlaff bewehrte Beton-Bahnschwelle handeln. Die Bahnschwelle mit Verbundplatte kann für abzweigungs- oder kreuzungsfreie Gleisabschnitte oder für Weichen, Kreuzungen oder Kreuzungsweichungen eingesetzt werden. Die Verbundplatte ist aber auch an der Unterseite anderer auf einem Untergrund, z. B. dem Erdboden aufliegender Betonkörper, wie z. B. Pflastersteine, Geh- oder Fahrwegplatten o.dgl. einsetzbar.

However, these uses of the composite panel do not constitute embodiments of this invention.
