Description

Die Erfindung betrifft eine Verbindungsvorrichtung zwischen Schwellenteilen bei Schwellen mit Überlänge für schienengebundene Verkehrswege, vornehmlich für Spannbeton-Weichenschwellen, die zur Montierbarkeit vor Ort aus mehreren vorgefertigten Schwellenteilen zu biegesteifen Längsschwellen zusammensetzbar sind, wie sie gattungsmäßig im Oberbegriff des Anspruchs 1 beschrieben ist. Als Schwelle mit Überlänge wird hier eine Schwelle bezeichnet, die deutlich länger als eine normale Gleisschwelle ist.The invention relates to a connecting device between threshold parts in sleepers with extra length for rail-bound traffic routes, primarily for prestressed concrete turnout sleepers, those for on-site assembly from several prefabricated ones Threshold parts can be assembled into rigid longitudinal sleepers, as they are is described generically in the preamble of claim 1. As an extra-long threshold here a threshold is called, which is significantly longer than a normal track threshold.

Schwellen mit Überlänge werden vornehmlich im Weichenbau gebraucht. Im Regelfall werden Weichen an Ort und Stelle des Einbaus aus gesondert angelieferten Schwellen, Schienen und Weichengestänge montiert. Dieses Verfahren ist arbeitsaufwendig. Neue Weichentypen werden im Herstellerwerk zur Kontrolle komplett vormontiert. Es liegt nahe, eine bereits vormontierte Weiche nicht für den Transport nochmals zu zerlegen, sondern sie im vormontierten Zustand zur Baustelle zu transportieren und einzubauen. Für einen Transport vormontierter Weichen bietet sich der Schienenweg an mit dem Transport der Weiche in waagerechter Lagerung auf Waggons. Auf diese Weise sind jedoch nur Weichenelemente bis zu einer Breite von etwa 2,80 m transportierbar. Im Bereich der Gleisabzweigung einer Weiche ergibt sich aufgrund der Überschneidung des durchgehenden Gleises mit dem abzweigenden Gleis und der damit verbundenen räumlichen Beengung der Zwang, unter beiden Gleisen durchlaufende Schwellen anzuordnen, die über 4,00 m lang werden können. Um ein über 4,00 m breites Weichenelement auf dem Schienenweg transportieren zu können, muß es geteilt werden in einen maximal etwa 2,80 m breiten Abschnitt und einen die über 2,80 m hinausgehende restliche Breite umfassenden Abschnitt. Overlength sleepers are mainly used in turnout construction. As a general rule switches are made on site from the installation of separately delivered sleepers, Rails and switch poles installed. This process is labor intensive. New Switch types are completely preassembled in the factory for inspection. It is obvious not to dismantle an already preassembled switch for transport, but to disassemble it to be transported and installed in the pre-assembled state to the construction site. For one Transporting pre-assembled turnouts is the ideal way to transport the Switch in horizontal storage on wagons. This way, however, are only Switch elements can be transported up to a width of about 2.80 m. In the field of Track branching of a switch results from the overlap of the continuous Track with the branching track and the associated spatial constriction of the Forced to arrange thresholds running under both tracks that are over 4.00 m long can be. Around a switch element over 4.00 m wide on the rail track To be able to transport it must be divided into a maximum of about 2.80 m wide Section and a section that extends beyond the remaining width of 2.80 m.

Die wie vor beschrieben begrenzten Weichenabschnitte können im vormontierten Zustand zur Einbaustelle transportiert und vor Ort mit üblichem Gleisverlegegerät eingebaut werden. Um fachgerecht unterstopft und lagestabil unter Verkehr gehalten werden zu können, müssen die bei der Teilung des Weichenelements durchtrennten Schwellen in ihrer Durchlaufwirkung über die gesamte Weichenbreite wiederhergestellt werden.The switch sections limited as described above can be in the preassembled state Installation site can be transported and installed on site using a conventional track laying device. Around They must be properly supported and kept stable under traffic When dividing the switch element, thresholds cut through in their continuous action be restored across the entire width of the switch.

Eine gattungsgleiche Konstruktion, mit der zugeordnete Schwellenteile in den für den Transport getrennten Weichenabschnitten wieder miteinander verbunden werden sollen, ist aus der DE 42 01 631 bekannt. Dabei werden zwei Schwellenteile durch eine auf den Oberflächen der Schwellenteile sich erstreckende und in den Oberflächen verankerte, den Zwischenraum zwischen den Teilen überbrückende, ebene Stahlplatte mehr oder weniger gelenkig verbunden. Die bekannte Verbindung ist in der Stoßstelle biegeweich und zum Teil auch weich im Hinblick auf die Übertragung von Querkräften. Diese bekannte Konstruktion stellt in der Fuge zwischen den Schwellenteilen die Eigenschaft der durchlaufenden monolithischen Schwelle nicht wieder her. Die Lagestabilität der Weiche ist im Bereich derartig gestoßener Schwellen vermindert.A construction of the same type, with the assigned threshold parts in the for the Transport separate switch sections are to be connected again known from DE 42 01 631. Two sleeper parts are replaced by one on the Surfaces of the threshold parts extending and anchored in the surfaces Flat steel plate bridging the gap between the parts more or less articulated. The known connection is flexible in the joint and partially also soft with regard to the transfer of lateral forces. This well-known construction represents the property of the continuous in the joint between the threshold parts monolithic threshold not recovering. The positional stability of the switch is in the range thresholds encountered in this way are reduced.

Der Erfindung liegt die Aufgabe zugrunde, eine Schwellenverbindung zu entwickeln, mit der vorgefertigte Spannbeton-Schwellenteile nachträglich biege-, zug- und schubfest so miteinander zu monolithisch wirkenden Schwelleneinheiten verbindbar sind, daß die Weiche bei der Montage im Schotterbett eben und planmäßig einbaubar ist und unter Verkehr formstabil bleibt.The invention has for its object to develop a threshold connection with which Prefabricated prestressed concrete sleeper parts subsequently resistant to bending, tensile and shear interconnectable to form monolithic threshold units that the switch when installed in a ballast bed is level and can be installed according to plan and under traffic remains dimensionally stable.

Die Aufgabe wird gelöst durch die Merkmale einer Verbindungsvorrichtung, wie sie im kennzeichnenden Teil des Anspruch 1 beschrieben sind.The object is achieved by the features of a connecting device, as in characterizing part of claim 1 are described.

Geeignete Konstruktionen für eine erfindungsgemäße Vorrichtung sind in den Unteransprüchen 2, 4, 9, 11 und 13 dargestellt.Suitable constructions for a device according to the invention are in the Subclaims 2, 4, 9, 11 and 13 are shown.

Besonders für Gleisunterhaltungsarbeiten und Reparaturen zweckmäßig ist die Ausbildung der erfindungsgemäßen Vorrichtung als wiederholt lösbare Verbindung nach Anspruch 16. Eine teilweise Lösung bis zur Gelenkwirkung kann bei Gleisunterhaltungsarbeiten zweckmäßig sein, wenn man den Aufbau von Biegespannungen vermeiden, Verschiebungen der Schwellenteile gegeneinander jedoch verhindern will. The training is particularly useful for track maintenance work and repairs the device according to the invention as a repeatedly releasable connection according to claim 16. A partial solution to the joint effect can be used in track maintenance work be useful if you avoid the build-up of bending stresses, displacements who wants to prevent threshold parts against each other.

Für gängige Weichentypen können mit den erfindungsgemäßen Verbindungsvorrichtungen ausgerüstete Schwellenteile vorgehalten und Weichen bei Bedarf vom Hersteller oder aus Lagerbestand vormontiert zur Einbaustelle transportiert und mit Hilfe üblichen Verlegegerätes wirtschaftlich eingebaut werden.For common switch types, the connecting devices according to the invention can be used Equipped sleeper parts are provided and switches are made by the manufacturer or if necessary Stock pre-assembled transported to the installation site and with the help of conventional laying equipment be installed economically.

Die Lösungen nach den Ansprüchen 2,4 sind besonders geeignet bei Schwellenfertigung im Spannbett. Bei der Spannbettfertigung wird von den Abstellungen, mit denen die einzelnen Schwellenteile abgelängt werden, zwischen aufeinander folgenden Teilen ein Zwischenraum freigehalten, in dem der Trennschnitt der Spannbewehrung vorgenommen wird. Dieser Zwischenraum wird für die bauliche Entwicklung einer Verbindungsvorrichtung nach den Ansprüchen 2 und 4 genutzt. Ihre Konstruktion steht mit den dafür erforderlichen Einbauelementen im Schwellenteil nicht über die Querschnittskontur des Schwellenteils hinaus, die durch den lichten Spannbettquerschnitt vorgegeben ist. Um die für Weichenschwellen erforderliche hohe Genauigkeit der Positionierung der Schwellenverbindungsmittel zu erreichen, werden die Verbindungsvorrichtungen soweit möglich bereits vormontiert in die Schalung eingebaut und bei Herstellung im Spannbett auf einer durchgehenden Schablone für die ungestoßene Langschwelle mit den Schwellenteilen betoniert.The solutions according to claims 2,4 are particularly suitable for threshold production in Fitted bed. In the case of the production of fitted beds, the positions with which the individual Threshold parts are cut to length, a space between successive parts kept clear by making the separating cut of the prestressing reinforcement. This Space is used for the structural development of a connecting device according to the Claims 2 and 4 used. Your construction stands with the necessary Installation elements in the sleeper part do not have the cross-sectional contour of the sleeper part that is determined by the clear cross-section of the bed. To the for Turnout thresholds required high accuracy of positioning the To reach threshold connection means, the connection devices become so far possibly already pre-assembled in the formwork and in production in the fitted bed a continuous template for the bumpy long sill with the threshold parts concreted.

Die Lösungen nach den Ansprüchen 9, 11 und 13 eignen sich auch für Schwellen, die in Umlaufschalungen hergestellt werden. In den Schwellen werden nur Aussparungen für Verschraubungen vorgesehen. Die Verbindungen werden in Form von Steg- und/oder Flanschlaschen nachträglich an den Schwellenaußenflächen aufgeschraubt. Für die genaue Positionierung der Einbauteile müssen hier jedoch besondere Schablonen in die Schalung eingebaut werden.The solutions according to claims 9, 11 and 13 are also suitable for thresholds in Circulation formwork are manufactured. In the thresholds there are only cutouts for Screw connections provided. The connections are in the form of web and / or Flange plates subsequently screwed onto the outer threshold surfaces. For the exact Positioning of the built-in parts, however, requires special templates in the formwork to be built in.

Die erfindungsgemäßen Verbindungen werden anhand von Beispielen in den Fig. 1 ÷ 12 erläutert.The compounds according to the invention are illustrated by way of examples in FIGS. 1-20 explained.
