Abstract
Description
Die Erfindung betrifft eine hochelastische Schienenbefestigung für Gleisanlagen, die klemmartig ausgebildete Spannelemente aufweist, die im montierten Zustand mittels jeweils einer Schraube an einer als Unterlage für einen Schienenfuß ausgebildeten Stahlplatte befestigt sind und eine die Schiene in Position haltende Klemmkraft ausüben, wobei die Stahlplatte unter Zwischenschaltung einer elastischen Platte mit einem Untergrund, wie einen Schwellenkörper, insbesondere eine Betonschwelle, über Schwellenanker oder dergleichen Schraubenmittel verbunden ist.The invention relates to a highly elastic rail fastening for track systems, the clamping-like clamping elements has, which are fastened in the mounted state by means of a screw on a trained as a support for a rail steel plate and exert a rail holding in position clamping force, the steel plate with the interposition of a elastic plate is connected to a substrate, such as a threshold body, in particular a concrete sleeper, threshold anchor or the like screw means.
Eine derartige Schienenbefestigung ist aus

Aus der
Es ist bekannt, unter Verwendung solcher oder anderer klemmenartigen Spannelemente (Schienenklemmen) indirekte, kraftschlüssig-elastische Schienenbefestigungen vorzusehen. Diese werden im Einsenbahnoberbau dann eingesetzt, wenn erhöhte Elastizität und/oder Dämpfung notwendig ist. Auf festen Fahrbahnen (Betonfahrbahn ohne Schotter) wird durch die hochelastische Schienenbefestigung die Schotterelastizität nachgebildet; auf Tunnelstrecken im Stadtbereich können mittels elastischer Schienenbefestigungen die Erschütterungen deutlich reduziert werden.It is known to provide using such or other clamp-like clamping elements (rail clamps) indirect, non-positive-elastic rail fasteners. These are used in the single-track superstructure when increased elasticity and / or damping is necessary. On solid roads (concrete roadway without gravel), the elasticity of the ballast is reproduced by the highly elastic rail fastening; On tunnels in urban areas, the vibrations can be significantly reduced by means of elastic rail fastenings.
Im praktischen Betrieb kommen indirekte Schienenbefestigungen dieser Art in verschiedenen Varianten zum Einsatz. Diesen ist gemeinsam, daß die Schiene über ihren Schienenfuß zunächst auf der Rippen- bzw. Unterlagsplatte (Stahloder Gussplatte) festgelegt wird und dann anschließend die Rippen-/Unterlagsplatte wiederum separat mit dem Schwellenkörper (aus Holz oder Beton) oder (auf Brücken) mit einer Betonplatte bzw. einem Stahlträger verbunden wird. Diese indirekten, elastischen Schienenbefestigungen benötigen zur Vorspannung der mindestens einen zwischengeschalteten, elastischen Platte zwei Schwellenanker (Schwellen- oder Durchsteckschrauben bzw. Ankerbolzen mit Sicherungsmutter) und zum Verspannen der beiden Spannelemente bzw. Schienenklemmen zwei separate Schrauben, z. B. Hakenschrauben. Die Schwellenanker und die Spannelemente-Schrauben sind dabei seitlich entfernt voneinander angeordnet.In practical operation, indirect rail fasteners of this type are used in various variants. This is common that the rail on their rail first on the rib or base plate (steel or cast iron plate) is set and then then the ribbed / base plate again separately with the threshold body (wood or concrete) or (on bridges) with a Concrete plate or a steel beam is connected. These indirect, elastic rail fasteners require to prestress the at least one intermediate, elastic plate two threshold anchor (threshold or through bolts or anchor bolt with lock nut) and to clamp the two clamping elements or rail clamps two separate screws, z. B. hook screws. The threshold anchor and the clamping elements screws are arranged laterally apart.
Durch die
Aber auch die aus dem praktischen Einsatz bekannten, vorbeschriebenen indirekten hochelastischen Schienenbefestigungen bringen Nachteile mit sich. So wird die vom Eisenbahnrad erzeugte Horizontalkraftkomponente vom Schwellenanker bzw. Ankerbolzen aufgenommen, womit an der Einspannstelle des Schwellenankers im Schwellenkörper ein Biegemoment, zusätzlich auch noch Scherung, hervorgerufen wird, was oft zu Brüchen an dieser Stelle führt. Weiterhin wird durch die Schraubbefestigung der Klemmelemente die zwischengeschaltete elastische Platte relativ stark vorgespannt, was deren Arbeitsbereich erheblich einschränkt. Die dabei unvermeidlich hohe Vorspannung der elastischen Platte, die bei ca. 12 bis 14 kN liegen kann, verursacht auf Dauer ein Kriechen des elastischen Materials, führt damit automatisch zu einer Verhärtung des Systems und somit zum deutlichen Wirkungsverlust der Elastizität bzw. Dämpfung.But also known from practical use, above-described indirect high-elastic rail fasteners have disadvantages. Thus, the horizontal force component generated by the railway wheel is absorbed by the threshold anchor or anchor bolt, which at the clamping point of the threshold anchor in the sleeper body a bending moment, in addition to shear, is caused, which often leads to fractures at this point. Furthermore, the intermediate elastic plate is biased relatively strong by screwing the clamping elements, which limits their work considerably. The thereby inevitably high bias of the elastic plate, which may be about 12 to 14 kN, caused in the long term, a creep of the elastic material, thus automatically leading to a hardening of the system and thus to the significant loss of effect of the elasticity or damping.
Die neben derartigen indirekten, kraftschlüssig-elastischen Schienenbefestigungen bekannten direkten elastischen Schienenbefestigungen, wie durch die
Ausgehend von einer indirekten, kraftschlüssig-elastischen bzw. hochelastischen Schienenbefestigung liegt der Erfindung daher die Aufgabe zugrunde, eine gattungsgemäße Schienenbefestigung ohne die beschriebenen Nachteile zu schaffen, d.h. insbesondere die hohe Vorspannung der zwischengeschalteten, elastischen Platte zu vermeiden und gleichzeitig ein kompaktes, kostengünstiges Befestigungssystem zu ermöglichen.Based on an indirect, non-positive-elastic or highly elastic rail fastening, the invention is therefore an object of the invention to provide a generic rail fastening without the disadvantages described, i. in particular to avoid the high bias of the intermediate, elastic plate while allowing a compact, cost-effective fastening system.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die die klemmenartigen Spannelemente befestigenden Schrauben und die Schwellenanker bzw. Schraubenmittel der Stahlplatte mit Abstand übereinander liegend angeordnet sind. Es lässt sich hiermit ein Befestigungssystem erreichen, das die Vorteile der indirekten und direkten Schienenbefestigung vereint und dabei aber deren Nachteile vermeidet. Indem die Schiene über die auf ihren Schienenfuß wirkenden, von den Schrauben beaufschlagten Spannelemente indirekt an der Stahlplatte befestigt ist und diese wiederum separat über Schwellenanker mit dem Schwellenkörper verbunden wird, wobei die Schwellenankerachsen vorzugsweise auf einer Linie, in Flucht mit den darüber angeordneten Achsen der Schrauben, die zur Befestigung der Spannelemente dienen, angeordnet sind, gleichwohl auch ein leichter seitlicher Versatz möglich wäre, lässt sich erreichen, daß die Spannelemente bzw. deren Befestigungsschrauben keiner Schwingwechselbeanspruchung ausgesetzt sind, somit lediglich rein statisch belastet werden. Abgesehen von der sehr kompakten Bauweise wird zudem gleichzeitig die hohe Vorspannung der elastischen bzw. hochelastischen Platte vermieden. Denn diese wird nicht mehr mit der Spannkraft der Spannklemme, sondern mit den Schwellenankern oder einem Ankersystem (z.B. Ankerbolzen mit selbstsichernder Mutter und Anschlag oder ähnliche Konstruktionen mit Schraube und Feder) mit sehr geringer Vorspannkraft von nur wenigen kN verspannt.This object is achieved in that the clamp-like clamping elements fastening screws and the threshold anchors or screw means of the steel plate are arranged at a distance from each other superimposed. It can hereby achieve a fastening system that combines the advantages of indirect and direct rail fastening while avoiding their disadvantages. In that the rail is indirectly fastened to the steel plate via the tensioning elements acted upon by the screws on its rail foot and in turn is connected to the sleeper body separately via threshold anchors, the sleeper anchor axles preferably being aligned with the axes of the screws arranged above them , which serve to fasten the clamping elements, are arranged, however, a slight lateral offset would be possible, it can be achieved that the clamping elements or their mounting screws are exposed to no vibration cycling, thus only purely static load. Apart from the very compact design also the high bias of the elastic or highly elastic plate is also avoided. Because this is no longer clamped with the clamping force of the tension clamp, but with the threshold anchors or an anchor system (eg anchor bolt with self-locking nut and stop or similar constructions with screw and spring) with very low biasing force of only a few kN.
Als klemmartiges Spannelement eignet sich jede Art Spannklemme, im einfachsten Fall ein Stahlblech als Klemmplatte. Denn die Verbindung des Spannelementes / der Klemme mit der Schiene und der Stahlplatte ist starr, so daß es kaum eine Relativbewegung zwischen Schiene und der Stahl- oder Gussplatte, an der die Klemme befestigt ist, gibt. Das Spannelement / die Klemme schwingt somit auch nicht und braucht daher nicht elastisch zu sein. Das Klemmelement darf sich nur nicht lösen, was durch eine selbstsichernde Mutter oder eine Schraube, mit oder ohne Federring, erreicht werden kann. Bei einer optionalen, federnden Klemme läßt sich die Federkraft als Sicherung gegen Lösen nutzen.As clamp-like clamping element is any kind of tension clamp, in the simplest case, a steel plate as a clamping plate. Because the connection of the clamping element / the clamp with the rail and the steel plate is rigid, so that there is hardly any relative movement between the rail and the steel or cast plate to which the clamp is attached, there. The clamping element / clamp thus does not oscillate and therefore does not need to be elastic. The clamping element may only not come loose, which can be achieved by a self-locking nut or a screw, with or without spring ring. With an optional, resilient clamp, the spring force can be used as a safeguard against loosening.
Die Ausschöpfung der Vorteile einer indirekten und direkten Schienenbefestigung werden nach einer bevorzugten Ausführung der Erfindung dadurch weiter begünstigt, daß sich die Stahlplatte über zweiteilige, in vertikaler Ebene einander anliegenden Winkelführungsplatten an Schultern des Schwellenkörpers abstützt. Die Winkelführungsplatten nehmen im Zusammenspiel mit den Schultern des Schwellenkörpers einerseits die Horizontal- bzw. Querkraft auf. Andererseits bietet die zweiteilige Ausführung der Winkelführungsplatten, die aus Kunststoff bestehen, im Gegensatz zu einteiligen Winkelführungsplatten den Vorteil, daß die Plattenteile gegeneinander gleiten, sobald das System durch die Achslasten belastet wird. Die ohnehin schon erreichte hohe Lebensdauer des erfindungsgemäßen Befestigungssystems wird dadurch weiter gefördert.The exploitation of the advantages of an indirect and direct rail fastening are favored according to a preferred embodiment of the invention further characterized in that the steel plate is supported on two parts, in vertical plane adjacent angular guide plates on shoulders of the threshold body. On the one hand, the angled guide plates, in interaction with the shoulders of the threshold body, absorb the horizontal or transverse force. On the other hand, the two-part design of the angle guide plates, which are made of plastic, in contrast to one-piece angled guide plates has the advantage that the plate members slide against each other when the system is loaded by the axle loads. The already achieved long service life of the fastening system according to the invention is thereby further promoted.
Die Horizontalkräfte können auch ohne ein seitliches Winkelführungselement aufgenommen werden, wenn als unteres Schraubenmittel ein Ankerbolzen großer Länge und mit hoher Festigkeit verwendet wird, womit ein sehr viel niedriger liegender Querkraftangriffspunkt und damit viel kleinerer Hebelarm erreicht werden kann, so daß das auf den Ankerbolzen wirkende Biegemoment deutlich geringer wird. Eine derartige Ankerbolzenbefestigung eignet sich insbesondere für feste Fahrbahnen, die aus einfachen Betonplatten ohne Schwellen bestehen.The horizontal forces can also be absorbed without a lateral angled guide element, if a bolt of long length and high strength is used as the lower screw means, whereby a much lower transverse force application point and thus much smaller lever arm can be achieved so that the bending moment acting on the anchor bolt is significantly lower. Such an anchor bolt attachment is particularly suitable for solid roads that consist of simple concrete slabs without thresholds.
Eine erfindungsgemäße Ausgestaltung sieht vor, daß die äußere, einer Schulter unmittelbar benachbarte Winkelführungsplatte mit einer Abhebesicherung ausgebildet ist. Diese kann eine Schraubankerhalterung sein oder beispielsweise auch geometrisch im Schwellenkörper integriert werden. In jedem Fall wird durch die Abhebesicherung die Einbaulage gewährleistet.An embodiment of the invention provides that the outer, a shoulder immediately adjacent angled guide plate is formed with a lift-off. This can be a Schraubankerhalterung or, for example, geometrically integrated in the threshold body. In any case, the installation position is guaranteed by the lift-off protection.
Wenn nach einem vorteilhaften Vorschlag der Erfindung die einander zugewandten Enden der Schrauben und der Schwellenanker als Kopfstücke ausgebildet sind, bieten die Köpfe der Schwellenanker eine automatische Begrenzung im Überlastfall. Denn sobald der Abstand, den Klemmelement-Schraube und Schwellenanker in der Ausgangs-Einbaulage einnehmen, überwunden wird, legt sich das Schwellenanker-Kopfstück an die gegenüber liegende Schraube an.If, according to an advantageous proposal of the invention, the facing ends of the screws and the threshold anchors are designed as headers, the heads of the threshold anchors provide an automatic limitation in case of overload. For as soon as the distance, occupying the clamping element screw and threshold anchor in the initial mounting position, is overcome, the threshold anchor head piece applies to the opposite screw.
Nach einer Ausgestaltung der Erfindung kann das Kopfstück der Schrauben in die Stahl- oder Gußplatte, auf der der Schienenfuß, ggf. unter Hinzufügung einer Zwischenplatte bzw. -lage festgelegt wird, eingeschraubt oder darin verrastet oder verkeilt, z. B. mittels eines Bajonettverschlusses, werden. In jedem Fall wird eine sichere Ankopplung der oberen Schraube gewährleistet.According to one embodiment of the invention, the head of the screws in the steel or cast plate on which the rail, if necessary, with the addition of an intermediate plate or -lage is set, screwed or locked therein or wedged, z. B. by means of a bayonet closure, be. In any case, a secure coupling of the upper screw is guaranteed.
Es kann auf dem von dem Kopfstück abgewandten Ende der oberen Schrauben vorteilhaft eine Standardmutter, für die sich im Zusammenspiel mit einem elastischen Spannelement ein selbstsichernder Sitz ergibt, oder in Verbindung mit einer Klemmplatte eine Sicherungsmutter aufgeschraubt werden.It can advantageously be screwed onto the end remote from the head end of the upper screws a standard nut, for the results in conjunction with an elastic clamping element a self-locking seat, or in conjunction with a clamping plate a lock nut.
Wenn die oberen Schrauben nach einem Vorschlag der Erfindung mit einer Durchgangsbohrung ausgebildet sind, läßt sich in einfacher Weise ein direkter Zugang zur unteren Schraube bzw. zum Schwellenanker / Ankerbolzen mittels eines Werkzeugs, z. B. Innensechskantwerkzeug, das in einen Innensechskant des unteren Kopfstückes eingreifen kann, erreichen.If the upper screws are formed according to a proposal of the invention with a through hole, can be in a simple way a direct access to the lower screw or the threshold anchor / anchor bolt by means of a tool, for. B. hexagon socket tool, which can engage in a hexagon socket of the lower head piece reach.
Es wird erfindungsgemäß vorgeschlagen, daß das Kopfstück der Schwellenanker mit radialem Freiraum in der Durchgangsbohrung der Stahlplatte angeordnet ist. Wenn die Schiene belastet wird, können sich die Schwellenanker somit ungehindert den darüber in der Durchgangsbohrung eingeschraubten Klemmelement-Schrauben nähern.It is proposed according to the invention that the head piece of the threshold anchor is arranged with radial clearance in the through hole of the steel plate. Thus, when the rail is loaded, the threshold anchors are free to approach the clamp screws screwed over the through hole.
Hierbei empfiehlt es sich nach vorteilhaften Ausgestaltungen der Erfindung, unter dem Kopfstück der Schwellenanker ein Federelement, z.B. Federring, Feder, Tellerfeder, Tellerfederpaket, Spiralfeder, Schraubenfeder, Gummiring oder Elastomerfeder, vorzusehen und den Schwellenankern unterhalb ihrer Kopfstücke in den Durchgangsbohrungen eine Isolierkragen- oder Gleitbuchse zuzuordnen. Dieses Federelement stellt in vorteilhafter Weise ein elastisches Gegenlager für die auf der hochelastischen Zwischenplatte angeordnete Stahl- / Gußplatte dar. Das Gegenlager für das Federelement ist das Kopfstück, ggf. in Form einer aufgeschraubten, selbstsichernden Mutter, ggf. mit Unterlegscheibe, des Schwellenankers.In this case, it is recommended according to advantageous embodiments of the invention, under the head piece of the threshold anchor, a spring element, e.g. Spring ring, spring, plate spring, disc spring package, coil spring, coil spring, rubber ring or elastomer spring to provide and assign the threshold anchors below their head pieces in the through holes an insulating collar or sliding bushing. This spring element is advantageously an elastic counter bearing for the arranged on the highly elastic intermediate plate steel / cast plate. The abutment for the spring element is the head piece, possibly in the form of a screwed, self-locking nut, possibly with washer, the threshold anchor.
