Abstract
Description
Die Erfindung bezieht sich auf eine Anordnung von Schwellen für Schienen mit einer Hohlschwelle, innerhalb der z.B. Abschnitte eines Weichenverschlusses angeordnet sind.The invention relates to an arrangement of sleepers for rails with a Hollow threshold within which e.g. Sections of a switch lock are arranged.
Aus der WO 94/05858 ist eine als Trogschwelle bezeichnete Hohlschwelle bekannt, in der ein Weichenverschluß integriert ist, um eine Weichenzunge zu einer Backenschiene zu verstellen. Die Trogschwelle weicht in ihrer Breite von üblichen Schwellen ab, so daß Probleme beim Stopfen des Schotters erwachsen können. Auch kann es vorkommen, daß der Abstand zu den zur Trogschwelle benachbarten Abstützungen der Schiene von dem zwischen zwei aufeinanderfolgenden normalen Schwellen abweicht, so daß sich insbesondere in Hochgeschwindigkeitsgleisen Unregelmäßigkeiten in bezug auf das Schwingungsverhalten ergeben können.From WO 94/05858 a hollow threshold known as a trough threshold is known, in which a switch lock is integrated to turn a switch tongue to a stock rail adjust. The width of the trough threshold differs from usual thresholds, so that Problems with tamping the ballast can arise. It can also happen that the Distance to the rail supports adjacent to the trough sleeper from the deviates two consecutive normal thresholds, so that it is particularly in high-speed tracks Irregularities in the vibration behavior result can.
Eine Hohlschwelle, die in ihrer Querschnittsbreite und - höhe einer normalen Beton- und Holzschwelle entspricht, ist der DE 43 15 200 A1 zu entnehmen.A hollow sleeper, the cross-sectional width and height of a normal concrete and Corresponds to wooden threshold, can be found in DE 43 15 200 A1.
Unabhängig von der Dimensionierung einer Hohlschwelle kann bei Belastung eine Schaukelbewegung aufgebaut werden, wodurch in der Schotterunterlage wiederum ein Freiarbeiten der Hohlschwelle erfolgen könnte. Regardless of the dimensioning of a hollow sleeper, a rocking movement can take place under load be built up, which in turn in the gravel underlay a free work of Hollow threshold could take place.
Aus der DE 44 14 504 C1 ist es bekannt, Weichenschwellen sohlenseitig mit Blechplatten zu
verbinden.From
Der vorliegenden Erfindung liegt das Problem zugrunde, eine Schwellenanordnung der eingangs genannten Art so weiterzubilden, daß eine Hohlschwelle nicht zu einer Gleisveränderung, insbesondere hinsichtlich des Schwingungsverhaltens führt. Auch soll sichergestellt sein, daß in der Hohlschwelle eine Schaukelbewegung nicht erzeugt werden kann. Schließlich soll nach einem weiteren Aspekt gewährleistet werden, daß ein Stopfen des Schotters im Bereich der Hohlschwelle mit üblichen Gerätschaften ohne irgendwelche Behinderungen erfolgen kann.The present invention is based on the problem of a threshold arrangement of the further developed in such a way that a hollow sleeper does not lead to a change of track, leads especially with regard to the vibration behavior. Also supposed to be ensured be that a swing movement can not be generated in the hollow threshold. Finally is to be ensured according to a further aspect that a plugging of the ballast in Area of the hollow sleeper with usual equipment without any obstructions can be done.
Das Problem wird erfindungsgemäß dadurch gelöst, daß die Hohlschwelle mit der jeweils benachbarten üblichen Schwelle wie Betonschwelle über einen in Längsrichtung der Schiene verlaufenden Träger verbunden ist, daß der Träger eine Steifigkeit derart aufweist, daß eine von dem Träger ausgehende Schienenabstützung entsprechend einer von einer üblichen Schwelle ausgehenden Abstützung einfederbar ist, und/oder daß eine von dem Träger ausgehende Abstützung beim Durchfahren der Schiene mit einem Fahrzeug eine Einsenkung erfährt, die der einer Abstützung einer üblichen Schwelle entspricht.The problem is solved according to the invention in that the hollow threshold with each neighboring usual threshold such as concrete sleeper in the longitudinal direction of the rail extending carrier is connected that the carrier has a rigidity such that a rail support proceeding from the carrier corresponding to one of a conventional one Threshold outgoing support is deflectable, and / or that an outgoing from the carrier Support when driving through the rail with a vehicle undergoes a depression which corresponds to a support of a usual threshold.
Durch die erfindungsgemäße Maßnahme erfährt die Hohlschwelle eine Verankerung mit den benachbarten Schwellen, so daß sichergestellt ist, daß insbesondere in Hochgeschwindigkeitsgleisen in der von der Masse her von den benachbarten Schwellen abweichenden Hohlschwelle keine Schaukelbewegung hervorgerufen werden kann, die zu einem Freiarbeiten führt. Ferner ist sichergestellt, daß sich im Bereich der Hohlschwelle und der Träger gleisähnliche Bedingungen einstellen, so daß sich eine Änderung des Fahrverhaltens für ein einen entsprechenden Gleisabschnitt durchfahrendes Schienenfahrzeug nicht ergibt.Through the measure according to the invention, the hollow tie is anchored to the neighboring sleepers, so that it is ensured that especially in high-speed tracks in that deviating in mass from the neighboring thresholds Hollow threshold no rocking movement can be caused, which leads to a free working leads. It is also ensured that there are track-like ones in the area of the hollow sleeper and the girder Set conditions so that a change in driving behavior for one corresponding rail section does not result in a rail vehicle.
Insbesondere sollte der Träger im Schnitt eine T-Form aufweisen, wobei vorzugsweise dessen Mittelschenkel von der Hohlschwelle ausgeht und beabstandet zu der benachbarten Schwelle endet. Selbstverständlich kann der Träger auch eine andere Geometrie wie z.B. im Schnitt eine U- oder Kastenform aufweisen. In particular, the carrier should have a T-shape in section, preferably the latter Middle leg starts from the hollow sleeper and is spaced from the neighboring sleeper ends. Of course, the carrier can also have a different geometry, e.g. on average have a U or box shape.
Um die erforderliche Steifigkeit, also Elastizität in den jeweiligen Trägern zu erzielen, ist vorgesehen, daß der Mittelsteg eine Höhe aufweist, die von der Hohlschwelle ausgehend in Richtung der benachbarten Schwelle abnimmt.In order to achieve the required rigidity, i.e. elasticity in the respective beams provided that the central web has a height starting from the hollow threshold in Direction of the neighboring threshold decreases.
Um eine einfache, jedoch sichere Befestigung des Trägers mit den benachbarten Schwellen sicherzustellen, ist vorgesehen, daß der Träger mit seinem Flansch auf der benachbarten Schwelle aufliegt und vorzugsweise Befestigung für eine auf der Schwelle angeordnete Schienenabstützung ist. Ferner ist der Träger selbst mit der Hohlschwelle vorzugsweise verschweißt. Andere Verbindungsarten sind selbstverständlich auch möglich.For a simple but secure attachment of the beam to the neighboring sleepers ensure it is provided that the carrier with its flange on the adjacent Threshold rests and preferably fastening for one arranged on the threshold Rail support is. Furthermore, the carrier itself with the hollow threshold is preferred welded. Other types of connection are of course also possible.
Um gleisähnliche Bedingungen nicht nur in bezug auf die Federeigenschaften, sondern auch hinsichtlich des Abstands zwischen Abstützungen untereinander zu erreichen, ist vorgesehen, daß die zu den Hohlschwellen benachbarten Schwellen einen Abstand untereinander aufweisen, der dem von vier Schwellen im normalen Gleis entspricht. Somit ist es nur erforderlich, daß von jedem Träger eine zusätzliche Abstützung ausgeht, wobei die Abstützungen untereinander bzw. jede Abstützung zu der benachbarten normalen Schwelle einen Abstand aufweist, der dem Abstand üblicher Schwellen untereinander entspricht.To track-like conditions not only in terms of spring properties, but also with regard to the distance between supports, it is provided that the sleepers adjacent to the hollow sleepers are at a distance from one another, which corresponds to that of four sleepers in the normal track. So it is only necessary that from each carrier comes an additional support, the supports a distance from each other or each support to the neighboring normal threshold has, which corresponds to the distance between common thresholds.
Des weiteren ist vorgesehen, daß die Hohlschwelle in Längsrichtung der Schiene eine Erstreckung aufweist, die gleich der der benachbarten üblichen Schwellen vor bzw. hinter der Hohlschwelle ist oder diesem Abstand in etwa entspricht, so daß die erfindungsgemäße Schwellenanordnung mit der Hohlschwelle problemlos und mit üblichen Maßnahmen gestopft werden kann.It is also provided that the hollow sleeper in the longitudinal direction of the rail Extent has the same as that of the neighboring usual thresholds before or after the Hollow threshold is or approximately corresponds to this distance, so that the invention Threshold arrangement with the hollow sleeper stuffed easily and with usual measures can be.

In der einzigen Figur ist ein Schnitt durch einen Gleisabschnitt mit zwei üblichen Schwellen
10, 12 und einer zwischen diesen angeordneten Hohlschwelle 14 dargestellt. Auf den
Schwellen 10 und 12 ist eine Schiene 16 über Abstützungen wie Rippen- oder Gleitstuhlplatten
18, 20 festgelegt. Hierbei handelt es sich um eine übliche Konstruktion des Schienenoberbaus,
so daß auf den einschlägigen Stand der Technik zu verweisen ist.In the single figure is a section through a track section with two
Im Ausführungsbeispiel weist die Hohlschwelle 14 im Schnitt eine U-Form und eine Breite
auf, die der der Schwellen 10 und 12 -wie Betonschwellen- entspricht. Hierbei handelt es
sich jedoch nur um eine besonders bevorzugte Maßnahme, ohne daß eine Einschränkung der
erfindungsgemäßen Lehre erfolgen soll.In the exemplary embodiment, the hollow sleeper 14 has a U-shape and a width on average
which corresponds to that of
Im Ausführungsbeispiel dient die Hohlschwelle 14 zur Aufnahme eines Klammerverschlusses 23 einer Weiche. Hierbei kann es sich um einen Weichenklammerverschluß entsprechend der WO 94/05858 oder der WO 95/03199 handeln.In the exemplary embodiment, the hollow threshold 14 serves to receive a clamp closure 23 a switch. This can be a switch clamp closure according to the WO 94/05858 or WO 95/03199 act.
Da sowohl die üblichen Schwellen 10 und 12, bei denen es sich um Betonschwellen handeln
kann, als auch die Hohlschwelle 14 in einem nicht dargestellten Schotterbett gelagert sind,
ist die Hohlschwelle 14 über Träger 22, 24 mit den benachbarten Schwellen 10 und 12
verbunden, um sicherzustellen, daß dann, wenn das Gleis von einem Fahrzeug durchfahren
wird, in der Hohlschwelle 14 keine Schaukelbewegung in einem Umfang hervorgerufen wird,
daß ein Freiarbeiten aus der Schotterunterlage erfolgen kann.Because both the
Die jeweiligen Träger 22 und 24 weisen im Schnitt eine T-Form auf, wobei der jeweilige
Mittelsteg 26, 28 von den Seitenwandungen 30, 32 der Trogschwelle 14 ausgeht und mit
diesen z.B. verschweißt ist.The
Der jeweilige Flansch 34, 36 des Trägers 22, 24 ist einerseits mit dem oberem Rand 38, 40
der Seitenwandungen 30, 32 der Trogschwelle 14 verschweißt und erstreckt sich andererseits
bis über die Oberseite 40, 42 der Schwelle 10 und 12. Dabei verläuft der Flansch 34, 36
zwischen der Oberseite 40, 42 der Schwelle 10, 12 und der Rippenplatte 18, 20.The
Auf dem Flansch 34, 36 sind des weiteren Abstützungen 44, 46 für die Schiene 16 angeordnet,
wobei der Abstand zwischen den Abstützungen 44, 46 untereinander und zu den
Schwellen 10 und 12 in etwa dem Abstand entspricht, der üblicherweise zwischen den
normalen Schwellen eines Gleises besteht.On the
Da die zu der Hohl- oder Trogschwelle 14 benachbarten Abstützungen 44, 46 jedoch nicht
von einer Schwelle, sondern von dem jeweiligen Träger 22, 24 ausgehen, ist erfindungsgemäß
vorgesehen, daß der jeweilige Träger 22, 24 in bezug auf seine Steifigkeit derart
ausgelegt ist, daß die Abstützungen 44, 46 beim Durchfahren eines Zuges eine Einfederung
erfahren, die der im Bereich der Abstützungen 18 und 20 der üblichen Schwellen 10 und 12
entspricht.However, since the supports 44, 46 adjacent to the hollow or trough sleeper 14 are not
starting from a threshold, but from the
So können die Träger 24, 26 derart ausgelegt sein, daß im Bereich der Abstützungen 44, 46
Abstützungen mit Werten im Bereich von in etwa 25 und 50 kN/mm auftreten. Dies
bedeutet, daß dann, wenn auf der Abstützung 44, 46 über ein Fahrzeug eine Kraft von 10 t
(100 kN) einwirkt, der Träger 24, 26 teilweise durch Verformung, teilweise durch Einsenkung
der benachbarten Beton- bzw. Hohlschwelle 10, 12, 14 um 2 - 4 mm einsinkt. Der
Träger 24, 26 selbst biegt sich um in etwa 1 - 1,5 mm, insbesondere um 1,33 mm bei einer
entsprechenden Krafteinleitung von 10 t durch.For example, the
Um mit konstruktiv einfachen Maßnahmen die erforderliche Steifigkeit zu realisieren, ist der
Mittelsteg 26, 28 des jeweiligen Trägers 22, 24 ausgehend von der Hohlschwelle 14 in
Richtung der benachbarten üblichen Schwelle 10, 12 in seiner Höhe abnehmend ausgebildet.
Ferner endet der Mittelsteg 22, 24 jeweils beabstandet zu der benachbarten Schwelle 10 und
12.In order to achieve the required rigidity with structurally simple measures, the
Durch die erfindungsgemäße Lehre ergibt sich der Vorteil, daß sich in einem Gleis im Bereich einer Hohlschwelle Verhältnisse ergeben, die denen im üblichen Gleis entsprechen. Dadurch, daß die Hohlschwelle 14 vorzugsweise eine Breitenerstreckung aufweist, die der üblicher Schwellen entspricht, kann mit üblichen Maßnahmen ein Stopfen des Unterbaus erfolgen. Gleichzeitig ergibt sich der für Trogschwellen bekannte Vorteil, daß ein Weichenverschluß innerhalb der Schwelle integriert werden kann, wodurch ein geschützter Einbau und eine Wartungsfreundlichkeit gegeben ist.The teaching of the invention has the advantage that in a track in Range of a hollow sleeper result in conditions that correspond to those in the usual track. Characterized in that the hollow threshold 14 preferably has a width that the Corresponding to usual thresholds, the substructure can be tamped with usual measures respectively. At the same time, there is the known advantage for trough sleepers that a switch lock can be integrated within the threshold, creating a protected installation and is easy to maintain.
