Description
Die Erfindung betrifft eine kraftschlüssig-elastische Schienenbefestigung für Gleisanlagen, die eine Schienenunterlagsplatte (6), eine Befestigungsanker (13) und ein mit Torsionsschenkeln klemmenartig ausgebildetes Spannelement aus elastischem Material, insbesondere aus gehärtetem Stahl aufweist, das im montierten Zustand mittels einer Halterung und dem diese vertikal durchsetzendem Befestigungsanker auf einem Schwellenkörper, insbesondere einer Betonschwelle, befestigt ist und eine die Schiene in Position haltende Klemmkraft ausübt, wobei die Schiene unter Zwischenschaltung einer Schienenunterlagsplatte auf dem Schwellenkörper anzuordnen ist.The invention relates to a frictional-elastic rail fastening for track systems, which has a rail support plate (6), a fastening anchor (13) and a torsion legs clamp-like clamping element made of elastic material, in particular hardened steel, in the assembled state by means of a holder and this vertically passing fastening anchor on a sleeper body, in particular a concrete sleeper, is attached and exerts a rail holding in position clamping force, the rail is to be arranged with the interposition of a rail support plate on the sleeper body.

Aus der
Der Erfindung liegt daher die Aufgabe zugrunde, eine gattungsgemäße, indirekte kraftschlüssig-elastische Schienenbefestigung ohne die genannten Nachteile zu schaffen, die weniger aufwendig herzustellende Bauteile und weniger Einbauraum benötigt sowie bei eingebautem Spannelement eine Montage bzw. Demontage der Befestigungsanker bzw. Schwellen-/Durchsteckschrauben erlaubt.The invention is therefore an object of the invention to provide a generic, indirect frictional-elastic rail fastening without the disadvantages mentioned, the less expensive to manufacture components and less installation space required and built-in tensioning element assembly or disassembly of the anchor fixing or threshold / through screws allowed ,
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schienenunterlagsplatte einstückig mit an ihren beiden Enden vorgesehenen, die Durchgangsbohrungen für die Befestigungsanker aufweisenden Haltergehäusen derart ausgebildet ist, daß einerseits die Spannelemente formschlüssig gehalten und andererseits die Haltergehäuse und damit einhergehend die Spannelemente von der mit ihrem Schienenfuß zwischen die Haltergehäuse einzusetzende Schiene vorgespannt sind. Indem somit erfindungsgemäß der Schienenfuß die vorzugsweise aus Guss oder hochfestem Kunststoff bestehenden Haltergehäuse und darüber die in diesen formschlüssig aufgenommenen Spannelemente vorspannt, behindern die mit ihren Torsionsschenkeln in den Haltergehäusen aufgenommenen Spannelemente nicht mehr den freien Zugang zu den Befestigungsankern. Diese lassen sich vielmehr durch die Spannelemente und die Haltergehäuse mittig von oben hindurch einfädeln bzw. einstecken und im Schwellenkörper verschrauben. Es werden lediglich zwei Befestigungsanker benötigt, wobei deren Montage unabhängig von den Spannelementen ist. Trotzdem ist es möglich, daß die beiden Befestigungsanker gleichzeitig eine nach einer bevorzugten Ausführung der Erfindung unter der Schienenunterlagsplatte liegende elastische Zwischenplatte um einen definierten Vorspannweg vorspannen, und zwar unabhängig von der Vorspannung der Spannelemente.This object is achieved in that the rail support plate integrally provided with at both ends, the through holes for the fastening anchor having holder housings is designed such that on the one hand held the clamping elements form fit and on the other hand, the holder housing and, consequently, the clamping elements of the with their rail between the holder housing to be used rail are biased. Thus, according to the present invention, the rail foot biases the preferably made of cast iron or high-strength plastic holder housing and above them positively received in this clamping elements hinder the recorded with their Torsionsschenkeln in the holder housings clamping elements no longer free access to the mounting anchors. These can be threaded through the clamping elements and the holder housing centrally from above or insert and screw in the sleeper body. There are only two mounting anchors required, their assembly is independent of the clamping elements. Nevertheless, it is possible that the two fastening anchors at the same time a according to a preferred embodiment of the invention below the rail underlay plate lying intermediate elastic plate around bias a defined biasing path, regardless of the bias of the clamping elements.
Die erreichte Kompaktheit des Systems ermöglicht es zudem, daß sich die Befestigungsanker weit näher als bei allen bekannten Schienenbefestigungen an den Schienenfuß heranführen lassen. Es kann daher eine optimale, gleichmäßig verteilte Vorspannung oder auch Verspannung der elastischen Zwischenplatte erfolgen, wenn man den Verspannungskegel betrachtet, den eine Schraube immer erzeugt.The achieved compactness of the system also makes it possible that the fastening anchors can be far closer than in all known rail fasteners to the rail foot can introduce. It can therefore be an optimal, evenly distributed bias or strain of the elastic intermediate plate, considering the stress cone, which always produces a screw.
Nach einer Ausgestaltung der Erfindung kann eine zwischen dem Schwellenkörper und der elastischen Zwischenplatte einlegbare Ausgleichsplatte vorgesehen werden. Damit ist ein durch die Einbauverhältnisse eventuell vorgegebener Höhenausgleich durch eine entsprechend angepasste Dicke der Ausgleichsplatte möglich. Der Aufbau kann gegebenenfalls durch zusätzliche Platten verändert bzw. erhöht werden.According to one embodiment of the invention, an insertable between the threshold body and the elastic intermediate plate compensation plate can be provided. Thus, a possibly predetermined by the installation conditions height compensation by a correspondingly adapted thickness of the balance plate is possible. The structure can optionally be changed or increased by additional plates.
Nach einem vorteilhaften Vorschlag der Erfindung lässt sich mindestens eine Isolationsdistanzzwischenlage zwischen dem Schienenfuß und den Haltergehäusen einpassen. Damit lässt sich der von der Breite des Schienenfußes bestimmte Abstand der beiden Haltergehäuse variabel verändern, so daß stets die über den Schienenfuß bewirkte Vorspannung der Haltergehäuse gewährleistet wird.According to an advantageous proposal of the invention, at least one isolation distance spacer between the rail and the holder housings can be fitted. Thus, the determined by the width of the rail foot distance of the two holder housing can be variably changed, so that always caused by the rail foot bias of the holder housing is guaranteed.
Wenn vorteilhaft in den Durchgangsbohrungen der Befestigungsanker eine beim Einschrauben der Befestigungsanker entsprechend dem Vorspannweg auf die elastische Zwischenplatte und/oder die Ausgleichsplatte die Vorspannkraft übertragende Distanzhülse angeordnet ist, lässt sich auf diese Weise durch Anziehen der Befestigungsanker die definierte Vorspannung erreichen.If advantageously in the through holes of the fastening anchor a screwing in the fastening anchor according to the Vorspannweg on the elastic intermediate plate and / or the compensating plate, the biasing force transmitted spacer sleeve is arranged, can be achieved in this way by tightening the fastening anchors the defined bias.
Alternativ ist vorteilhaft eine Einstellung des Vorspannweges über ein definiertes Schraubendrehmoment der Befestigungsanker möglich, d.h. ein Distanzelement bzw. eine -hülse ist in diesem Fall entbehrlich.Alternatively, it is advantageously possible to adjust the preload path via a defined screw torque of the attachment anchors, i. a spacer or sleeve is dispensable in this case.
Bei der Schienenbefestigung empfiehlt sich ein zwischen den Schraubenköpfen und den Haltergehäusen angeordnetes Federelement. Dieses kann aus elastischem Kunststoff bestehen oder als Tellerfeder ausgebildet sein und verhindert ein abruptes Ansteigen des Schraubendrehmomentes und damit ein Herausziehen des Dübels aus dem Schwellenkörper.When mounting rails, a spring element is recommended between the screw heads and the holder housings. This may consist of elastic plastic or be designed as a plate spring and prevents an abrupt increase in the screw torque and thus a withdrawal of the anchor from the threshold body.
Nach einer Ausgestaltung der Erfindung ist die Schienenunterlagsplatte zwischen höckerartigen Widerlagern des Schwellenkörpers aufgenommen und damit in ihrer Einbaulage fixiert.According to one embodiment of the invention, the rail support plate is received between hump-like abutments of the threshold body and thus fixed in its installed position.
Eine bevorzugte Ausführung der Erfindung sieht vor, daß zwischen den Widerlagern und der Schienenunterlagsplatte elastische Seitengleiteinlagen angeordnet sind. Diese dienen nicht nur zur exakten Positionierung sowie Querkraftdämpfung und Führung der einfedernden Schienenunterlagsplatte, sondern ebenfalls zur Übertragung der Rad- bzw. Schienenquerkraft auf die Widerlager, bei einer Betonschwelle ausgebildet als Betonhöcker.A preferred embodiment of the invention provides that elastic side sliding inserts are arranged between the abutments and the rail support plate. These serve not only for exact positioning and lateral force damping and guidance of the spring-loaded rail support plate, but also for transmitting the wheel or rail lateral force on the abutment, formed at a concrete sleeper as concrete hump.
Zweckmäßige Ausgestaltungen der Erfindung sehen vor, daß die elastischen Seitengleiteinlagen mit Einraststegen in Vertiefungen des Schwellenkörpers und/oder der höckerartigen Widerlager eingreifen. Dazu können sie mit sich nach vorne erstreckenden Fussstegen und/oder an ihren rückwärtigen, den höckerartigen Widerlagern des Schwellenkörpers zugewandten Seiten mit mindestens einem Eingreifvorsprung versehen sein. Die Seitengleiteinlagen werden hierdurch in Schienenlängsrichtung gehalten.Advantageous embodiments of the invention provide that the elastic side sliding inserts engage with latching webs in depressions of the threshold body and / or the hump-like abutment. For this purpose, they can be provided with at least one engagement projection with footrests extending forwards and / or at their rear sides facing the bump-like abutments of the threshold body. The side sliding inserts are thereby held in the rail longitudinal direction.
Nach einem vorteilhaften Vorschlag der Erfindung sind die elastischen Seitengleiteinlagen mit einander zugewandten Aussparungen ausgebildet, in die die elastische Zwischenplatte und/oder die Ausgleichsplatte stirnendseitig eintaucht. Die Seitengleiteinlagen werden somit zusätzlich niedergehalten und können aus ihrer Einbaulage nicht vertikal nach oben herausgedrückt werden.According to an advantageous proposal of the invention, the elastic side sliding inserts are formed with mutually facing recesses into which the elastic intermediate plate and / or the balance plate dips end face. The side glide inserts are thus additionally held down and can not be pushed out of their installation position vertically upwards.
Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, daß die elastischen Seitengleiteinlagen an ihren oberen, vom Schwellenkörper entfernten Enden mit die Kräfte in Schienenlängsrichtung von der Schienenunterlagsplatte aufnehmenden und in den Schwellenkörper ableitenden Schultern ausgebildet sind.A further preferred embodiment of the invention provides that the elastic side sliding inserts are formed at their upper, remote from the sleeper body ends with the forces in the rail longitudinal direction of the rail support plate receiving and in the emerging body-derived shoulders.
