Description
Die Erfindung betrifft eine Rahmenschwelle für einen Eisenbahnschotteroberbau bestehend aus zwei Querschwellen mit zwei unter den Schienen verlaufenden Längsträgern gemäß dem Oberbegriff des Anspruchs 1 und ein Verfahren zur Herstellung dieser Schwelle.The invention relates to a frame threshold for a railway ballast track consisting of two sleepers with two extending under the rails longitudinal beams according to the preamble of
Monolithische Spannbetonschwellen bestehend aus Querschwellen und unter den Schienen verlaufenden Längsträgern, im folgenden als Rahmenschwellen bezeichnet, sind in verschiedenen Ausführungsformen bekannt. Ihre Vorteile gegenüber dem klassischen Schotteroberbau mit Querschwellen allein bestehen einmal in der vergrößerten Auflagerfläche auf dem Schotter, zum anderen im erhöhten Querverschiebewiderstand der Einzelschwellen und in der besseren horizontalen Rahmentragwirkung des Gleisrostes.Monolithic prestressed concrete sleepers consisting of sleepers and under the rails extending longitudinal beams, hereinafter referred to as frame thresholds are known in various embodiments. Their advantages compared to the classic ballast track with sleepers alone are once in the enlarged bearing surface on the gravel, on the other hand in the increased lateral displacement resistance of the single sleepers and in the better horizontal frame support of the track grid.
Bekannte Ausführungsarten der Rahmenschwelle gemäß
Üblicherweise werden Querschwellen auf beiden Seiten jeder Schiene durchgehend mit einer auf dem Gleis fahrenden Maschine gestopft. Dabei wird nur der schmale Bereich unter den Schienen nicht erfaßt, weil die von oben angreifenden Stopfpickel diesen Abschnitt nicht erreichen können. Die breiten Längsträger der Rahmenschwellen vergrößern diesen nicht erfaßbaren Bereich und behindern damit die notwendige Schotterverdichtung unter den Querschwellen deutlich stärker. Breite Längsträger bei Rahmenschwellen sind deshalb für die als ersten Arbeitsgang durchzuführende Querschwellenstopfung ungünstig.Usually, sleepers on both sides of each rail are stuffed continuously with a machine moving on the track. In this case, only the narrow area under the rails is not detected, because the attacking from above tamping can not reach this section. The wide side members of the frame thresholds increase this non-detectable area and thus hinder the necessary ballast compaction under the sleepers much stronger. Wide side members with frame thresholds are therefore unfavorable for the first step to be performed cross-threshold clogging.
Darüberhinaus ist bei Rahmenschwellen ein zweiter Stopfvorgang zur Verdichtung des Schotters unter den Längsträgern erforderlich, der mit Hilfe einer zweiten, speziellen Maschine im Anschluß an die Stopfung der Querschwellen vorgenommen wird. Kosten und Zeitbedarf für die Stopfarbeiten werden damit erhöht.Moreover, with frame sleepers, a second stuffing operation is required to compact the ballast under the side members, using a second, special one Machine is made following the tamping of the sleepers. Costs and time required for the tamping work are increased.
Ein weiterer Nachteil ergibt sich daraus, daß die genaue Höhenlage des Gleises im Zuge der Querschwellenstopfung geschaffen wird. Bei der anschließenden Längsträgerstopfung ist aber eine unbeabsichtigte Anhebung der gesamten Rahmenschwelle durch zu intensives Stopfen möglich. Beide Stopfvorgänge beeinflussen sich also gegenseitig in Hinsicht auf die Höhenlage der Schwellen. Eine Lageverschlechterung des Gleises bei unsachgemäßer Stopfung der Längsträger ist nicht auszuschließen.Another disadvantage arises from the fact that the exact height of the track is created in the course of the cross-threshold clogging. In the subsequent Längsträgerstopfung but unintentional increase in the overall frame threshold is possible by too intensive plugging. Both stuffing processes thus influence each other in terms of the altitude of the thresholds. A deterioration of the track in case of improper stuffing of the side members can not be excluded.
Als Nachteil monolithischer Rahmenschwellen gilt weiterhin, daß bei schlechter Gleisunterhaltung örtliche Hohllagen auftreten, die zu einer Verwindung des Rahmens bis zu dessen Bruch führen können. Dieser Nachteil kann bisher nur durch eine kräftige, zweiachsige Vorspannung des Rahmens beseitigt werden. Die dazu notwendigen Fertigungseinrichtungen sind jedoch aufwendig und kostensteigernd.Another disadvantage of monolithic frame thresholds is that, in the case of poor track maintenance, local hollow layers occur which can lead to distortion of the frame until it breaks. This disadvantage can be eliminated so far only by a strong, biaxial bias of the frame. However, the necessary manufacturing facilities are consuming and cost-increasing.
Die Fertigung von Rahmenschwellen in Form momolithischer Tragelemente erfordert weiterhin den Bau neuartiger Fertigungseinrichtungen, die eine gleichzeitige, zweiachsige Vorspannung in Längs- und Querrichtung des Rahmens ermöglichen.. Bestehende Anlagen zur Herstellung von Querschwellen sind nicht einsetzbar. Synergieeffekte in der Fertigung sind deshalb nicht möglich.The production of frame sleepers in the form of momolithic support elements also requires the construction of novel manufacturing facilities that allow simultaneous, two-axis bias in the longitudinal and transverse directions of the frame. Existing facilities for the production of sleepers are not applicable. Synergy effects in production are therefore not possible.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Rahmenschwelle zu schaffen, bei der die Randbedingungen für ein wirkungsvolles Stopfen vereinfacht und verbessert sind, bei der die Bruchgefahr infolge einer Verwindung der Rahmenschwelle deutlich reduziert wird und die unter Anwendung vorhandener Querschwellenfertigungen herstellbar ist.The invention is therefore an object of the invention to provide a frame threshold, in which the boundary conditions for effective plug are simplified and improved, in which the risk of breakage due to distortion of the frame threshold is significantly reduced and which can be produced using existing cross sleeper manufacturing.
Die Aufgabe wird durch die Merkmale der Patentansprüche 1 und 9 der Erfindung gelöst.The object is solved by the features of
Die Erfindung geht von der Erkenntnis aus, daß die oben genannten Nachteile der Rahmenschwelle vorzugsweise durch eine raumsparende Ausbildung der Längsträger beseitigt werden können, die einerseits horizontal eine möglichst schubsteife Verbindung zwischen den Querschwellen schafft und andererseits eine gegenseitige Verwindung der Querschwellen erlaubt. Außerdem sollen sich die Längsträger nachträglich und unabhängig von der Querschwellenfertigung herstellen lassen.The invention is based on the recognition that the above-mentioned disadvantages of the frame threshold preferably by a space-saving design of the side members can be eliminated, on the one hand creates a horizontally as rigid as possible connection between the sleepers and on the other hand allows mutual twisting of the sleepers. In addition, the side members should be produced later and independently of the cross sleeper production.
Mit der in der Erfindung vorgeschlagenen Auflösung des Längsträgers in mehrere, fachwerk- und rahmenartig wirkende Diagonalstäbe läßt sich diese Erkenntnis in folgender Weise verwirklichen.With the proposed in the invention, the resolution of the longitudinal beam in a plurality, trussworking and frame-like acting diagonal bars, this realization can be realized in the following manner.
Die fachwerkartige Anordnung der Diagonalstäbe im Schwellengrundriß führt zu einer Reihe von Vorteilen:
- Der breite Längsträger bekannter Rahmenschwellen wird ersetzt durch mindestens zwei Diagonalstäbe, deren geringer Platzbedarf die Schienenfußbreite im wesentlichen nicht überschreitet Damit ist ein unbehindertes und wirksames Stopfen der Querschwellen möglich. Das Stopfen der Längsträger und damit das Risiko einer unbeabsichtigten Verschlechterung der Gleislage entfällt.
- Die aus der horizontalen Rahmentragwirkung entstehenden Schubkräfte zwischen den Querschwellen werden durch die als Fachwerk wirkenden Diagonalstäbe sicher übertragen.
- Die Verankerung der Diagonalstäbe erfolgt nicht im hochbeanspruchten Auflagerbereich der Querschwellen, sondern dank der Diagonalstabspreizung seitlich davon in weniger beanspruchten Zonen.
- The wide side member known frame thresholds is replaced by at least two diagonal bars, the small footprint does not substantially exceed the Schienenfußbreite This is an unobstructed and effective plugging of the sleepers possible. The plugging of the longitudinal members and thus the risk of unintentional deterioration of the track position is eliminated.
- The resulting from the horizontal frame effect thrust forces between the sleepers are securely transmitted by acting as truss diagonal bars.
- The anchoring of the diagonal bars does not take place in the highly stressed support area of the sleepers, but thanks to the diagonal bar spread laterally in less stressed zones.
In der Vertikalebene liegen die Diagonalstäbe hingegen vorzugsweise übereinander in zwei horizontalen Ebenen und führen damit zu folgenden Eigenschaften der Rahmenschwelle:
- Die elastischen Diagonalstäbe bilden zusammen mit den Querschwellen einen Rahmen, der bei einer gegenseitigen Verwindung der Querschwellen größere Vertikalverformungen ohne Überlastung der Einzelteile aufnimmt. Die Bruchgefahr beim Auftreten von örtlichen Hohllagen wird damit deutlich verringert.
- Das unerwünschte Kippen der Querschwellen um ihre Längsachse unter der Radlast wird wie bei bekannten Rahmenschwellen weitgehend beseitigt dadurch, daß die Rahmenwirkung eine gegenseitige Verdrehung der beiden angeschlossenen Querschwellen verhindert.
- Als Reaktion auf das Kippen der Querschwellen entstehen in den Diagonalstäben Zug- und Druckkräfte. Die in Querschwellenlängsachse gerichteten Kraftkomponenten der Diagonalstäbe sollten sich dabei gegenseitig ausgleichen. Um diesen Kraftausgleich zu erreichen, müssen die Diagonalstäbe symmetrisch zur Gleislängsachse angeordnet sein.
- Die übereinanderliegenden Diagonalstäbe bilden eine ausreichend große, vertikale Fläche zur Aktivierung des quer zum Gleis wirkenden Schotterwiderstandes. Dadurch bleibt der Querverschiebewiderstand der erfindungsgemäßen Rahmenschwelle gegenüber bekannten Ausführungsarten weitgehend erhalten.
- The elastic diagonal bars, together with the sleepers, form a frame which absorbs large vertical deformations without overloading the individual parts when the sleepers cross each other. The risk of breakage in the presence of local hollow layers is thus significantly reduced.
- The unwanted tilting of the sleepers about their longitudinal axis under the wheel load is largely eliminated as in known frame thresholds characterized in that the frame effect prevents mutual rotation of the two connected sleepers.
- In response to the tilting of the sleepers tensile and compressive forces arise in the diagonal bars. The force components of the diagonal bars, which are directed in the transverse sleeper longitudinal axis, should compensate each other. To achieve this force balance, the diagonal bars must be arranged symmetrically to the track longitudinal axis.
- The superimposed diagonal bars form a sufficiently large, vertical surface for activating the gravel resistance acting across the track. As a result, the transverse displacement resistance of the frame threshold according to the invention over known embodiments remains largely intact.
Die Verwendung der Diagonalstäbe führt auch in Hinsicht auf die erforderlichen Fertigungsvorrichtungen zu Vorteilen:
- Wegen der erfindungsgemäßen Auflösung der Längsträger in Diagonalstäbe entfällt auch die bisher bei monolithischen Rahmenschwellen erforderliche, zweiachsige Vorspannung. Damit können die einachsig vorgespannten Querschwellen vorab in schon vorhandenen Anlagen hergestellt werden. Der Zusammenbau zu einer Rahmenschwelle erfolgt in einem weiteren Fertigungsschritt.
- Das erfindungsgemäße Herstellungsverfahren führt wegen der Beschränkung auf bekannte Einzelschritte, wie z.B. das Einbauen und Verpressen der Diagonalstäbe zu einfachen Arbeitsvorgängen und geringen Investitionen für die Fertigung.
- Because of the inventive resolution of the side members in diagonal bars also eliminates the previously required in monolithic frame thresholds, biaxial bias. Thus, the uniaxially prestressed sleepers can be prepared beforehand in existing systems. The assembly to a frame threshold takes place in a further production step.
- Because of the restriction to known individual steps, such as, for example, the installation and compression of the diagonal bars, the production method according to the invention leads to simple work processes and low investments for production.

Als Querschwellen 1 können je nach Anforderung beliebige Schwellentypen eingesetzt werden. Die Anzahl und Größe der vorzusehenden Diagonalstäbe 2 hängt einerseits von der Beanspruchung der Rahmenschwelle ab. Andererseits ist auch die Lage der Spannbewehrung in den Querschwellen 1 von Bedeutung, da die rohrförmigen Öffnungen 4 zwischen den einzelnen Vorspannelementen der Querschwellen 1 Platz finden müssen.As a

Über den Verpressmörtelanschluß 10 wird dann der Verpressmörtel 6 von unten nach oben ansteigend injiziert. Um Lufteinschlüsse im Verpreßmörtel 6 zu vermeiden, sollte der Kippwinkel der Fertigungsplattform 8 vorzugsweise mindestens 45° gegen die Horizontale erreichen. Die Enden der rohrförmigen Öffnungen 4 werden nach Abschluß des Verpressvorganges mit wiedergewinnbaren Stopfen verschlossen.

Unter umgekehrten Bedingungen ist das Bohren der Öffnungen 4 an den fertigen Querschwellen 1 vorzuziehen, wobei auf ausreichenden Abstand der Bohrlöcher von den Spannelementen und auf ausreichende Rauhigkeit der Bohrlochwände zu achten ist.Under reverse conditions, it is preferable to drill the
Die Herstellung der erfindungsgemäßen Rahmenschwelle ist nicht auf das hier vorgeschlagene Verfahren beschränkt. Die Schwelle kann ebenso mit bekannten Methoden im einstufigen Verfahren produziert werden.The production of the frame threshold according to the invention is not limited to the method proposed here. The threshold can also be produced by known methods in a one-step process.
Eine bevorzugte, einstufige Herstellart besteht zum Beispiel darin, zwischen zwei nebeneinander angeordneten Formen die Diagonalstäbe 2 einzulegen und dann beide Schwellen gleichzeitig zu betonieren. Die durch Schlitze in die Formen hineinragenden Enden der Diagonalstäbe 2 werden mit der Erhärtung des Querschwellenbetons auf Haftung verankert. Das Herstellen der Öffnungen 4 und der spätere Verpressvorgang entfallen.For example, a preferred, one-stage production method consists of inserting the
