Abstract
Description
Die Erfindung betrifft einen Schwellenrahmen für eine Gleisanlage für schienengebundene
Fahrzeuge, insbesondere für einen Schotteroberbau, mit den Merkmalen
des Oberbegriffs des Patentanspruchs 1.The invention relates to a sleeper frame for a track system for rail-bound
Vehicles, in particular for a ballast track, with the features
the preamble of
Ein derartiges Bauelement ist aus der CH 545 376 bekannt Gegenüber dem gebräuchlichen Schötteroberbau mit Querschwellen haben Schwellenrahmen den Vorteil einer gleichmäßigeren Auflagerung im Schotter, einer geringeren Schotterpressung unter den Radlästen und eines erhöhten Querverschiebewiderstandes.Such a component is known from CH 545 376 compared to the conventional one Ballast superstructure with cross sleepers have threshold frames Advantage of a more uniform bedding in the ballast, a lower ballast pressure under the wheel arches and an increased lateral displacement resistance.
Die größere Länge der Schwellenrahmen in Gleislängsrichtung führt jedoch auch zu Nachteilen: Die Querfugen zwischen den Schwellenrahmen müssen zur Vermeidung von schädlichen Fugenbewegungen kraftschlüssig miteinander verbunden werden. Die notwendige elastische, vertikale Einsenkung der Schiene unter dem rollenden Rad erfordert wegen der geringen Rahmenverformungen im Schotter zusätzliche, hochelastische Auflagerkonstruktionen zwischen Schiene und Schwellenrahmen, die andererseits aber das unerwünschte Kippen der Schiene in der Schienenbefestigung begünstigen. Weiterhin führt der gleichmäßige und verhältnismäßig geringe Abstand von Querschwellen und Schienenbefestigungen in Gleislängsrichtung unter der rollenden Last zu Schwingungen im Schotter, die die Lagebeständigkeit des Oberbaus erheblich verschlechtern.However, the longer length of the sleeper frames in the longitudinal direction also leads to drawbacks: The transverse joints between the threshold frames must be avoided connected by harmful joint movements become. The necessary elastic, vertical depression of the rail under the rolling wheel requires due to the low frame deformation in the Ballast additional, highly elastic support structures between the rails and threshold frames, which on the other hand the undesired tilting of the Favor the rail in the rail fastening. Furthermore, the leads evenly and relatively short distance from cross sleepers and rail fastenings in the longitudinal direction of the track under the rolling load to vibrate in the gravel, which considerably impair the stability of the superstructure.
Die Nachteile dieser Konstruktion liegen vor allem in dem hohen technischen und wirtschaftlichen Aufwand für die Fugenverbindung. The main drawbacks of this construction are the high technical level and economic effort for the joint connection.
Des Weiteren ist aus der AT-PS 377 806 ein Eisenbahnoberbau bekannt, bei dem einzelne Rahmenelemente aneinandergereiht werden, wobei jede Schiene auf einem Rahmenelement mittels mehrerer Außager gelagert ist. Die Rahmenelemente können mittels Dübel an den Stirnseiten zur Aufnahme größerer Querkräfte verbunden sein. Die Bewehrung dieser in Spannbetonbauweise hergestellten Elemente erfolgt durch Spannglieder, die jeweils zwischen zwei einander gegenüberliegenden Stirnseiten des Elements geradlinig verlaufen.Furthermore, a railway superstructure is known from AT-PS 377 806, in which individual frame elements are strung together, each rail on a frame element is mounted by means of several outsourcers. The frame elements can use dowels on the end faces to absorb larger transverse forces be connected. The reinforcement of this manufactured in prestressed concrete Elements are made by tendons, each between two each other opposite end faces of the element run straight.
Diese Konstruktion weist den Nachteil auf, dass zur Aufnahme hoher Querkräfte ebenfalls eine Verbindung der Rahmenelemente erforderlich ist, was einen entsprechenden Herstellungs- und Montageaufwand bedingt. Zudem. ergeben sich durch den relativ großen Abstand der Schienenauflager innerhalb eines Elements bei einer Belastung mit einem Rad eines Schienenfahrzeugs entsprechende Vibrationen infolge des unterschiedlichen Durchbiegungsverhaltens der Schiene. Die Herstellung als Spannbetonteil mit jeweils in Längs- und Querrichtung verlaufenden Bewehrungselementen erfordert das Spannen in zwei zueinander senkrechten Richtungen. Auch dies bedeutet einen beträchtlichen Herstellungsaufwand.This construction has the disadvantage that it has to absorb high transverse forces a connection of the frame elements is also required, which is a corresponding Manufacturing and assembly costs. In addition. surrender due to the relatively large distance between the rail supports within an element corresponding vibrations when loaded with a wheel of a rail vehicle due to the different deflection behavior of the rail. The production as a prestressed concrete part with longitudinal and transverse directions Reinforcement elements require tensioning in two perpendicular to each other Directions. This also means a considerable manufacturing effort.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Schwellenrahmen für eine Gleisanlage für schienengebundene Fahrzeuge, insbesondere für einen Schotteroberbau, zu schaffen, bei dem auch bei hohen Querkräften keine aufwendige Verbindung der Schwellenrahmen in den Querfugen oder hochelastische Schienenauflager im Bereich der Schienenbefestigungen notwendig sind und der eine Verringerung der Frequenz der im Schienenfahrzeug erzeugten Schwingungen ermöglicht. Des Weiteren soll ein einfaches und kostengünstiges Verfahren zur Herstellung derartiger Schwellenrahmen geschaffen werden. The present invention is therefore based on the object of a threshold frame for a track system for rail vehicles, especially for to create a ballast superstructure in which none, even with high lateral forces elaborate connection of the threshold frames in the transverse joints or highly elastic Rail supports in the area of the rail fastenings are necessary and a decrease in the frequency of those generated in the rail vehicle Allows vibrations. Furthermore, a simple and inexpensive Methods for producing such threshold frames are created.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
Die besonderen Vorteile des erfindungsgemäßen Schwellenrahmens bestehen darin, dass durch die nach außen an den Rahmenrand gelegten Schienenbefestigungen einerseits die vertikale Klaffung in der Querfuge soweit vermindert wird, auf eine Verbindung zwischen den Schwellenrahmen verzichtet werden kann; Zudem wird auf diese Weise der Abstand zwischen den Schienenbefestigungen erheblich vergrößert mit der Folge, dass sich die Frequenz von Schwingungen entsprechend verringert.The particular advantages of the threshold frame according to the invention exist in that through the rail fastenings placed on the outside of the frame edge on the one hand the vertical gap in the transverse joint is reduced as far as possible, a connection between the threshold frames can be dispensed with can; In addition, the distance between the rail fastenings is in this way significantly increased with the result that the frequency of vibrations reduced accordingly.
Nach einer Ausführungsform der Erfindung weisen die äußeren Schienenauflager im Bereich Schienenbefestigungen eine große Steifigkeit und das mittlere Schienenauflager eine geringe Steifigkeit auf, wobei die Auflageoberfläche des mittleren Schienenauflagers vor der Schienenmontage deutlich höher liegt als die der äußeren Schienenauflager, so dass mit dem Anspannen der Schienenbefestigungen das mittlere Schienenauflager bis auf die Höhe der äußeren Schienenauflager zusammengedrückt wird und eine Druckvorspannung erhält.According to one embodiment of the invention, the outer rail supports great rigidity in the area of rail fastenings and the medium one Rail support on a low rigidity, the surface of the support middle rail support before the rail assembly is significantly higher than that the outer rail support so that the rail fastenings are tightened the middle rail support up to the height of the outer rail supports is compressed and receives a compressive prestress.
Hierdurch ergibt sich der Vorteil, dass die sog. Abhebewelle der Schiene, die sich in Fahrtrichtung hinter einem Rad des Schienenfahrzeugs einstellt, dennoch vom mittleren Auflager unterstützt wird und sich somit die Schiene im Bereich der Abhebewelle nicht vom Auflager abhebt. Die dämpfende Wirkung des elastischen mittleren Auflagers bleibt erhalten.This has the advantage that the so-called lifting shaft of the rail adjusts itself in the direction of travel behind a wheel of the rail vehicle, nevertheless is supported by the middle support and thus the rail in the area the lifting shaft does not lift off the support. The cushioning effect of the elastic middle support remains.
Nach einer weiteren Ausführungsform der Erfindung ist an der Unterseite der Querschwellen und/oder der Längsträger ein elastisches Material, vorzugsweise eine elastische Matte vorgesehen. According to a further embodiment of the invention, the Cross sleepers and / or the side members an elastic material, preferably an elastic mat is provided.
Hierdurch wird erreicht, dass die unter dem Schwellenrahmen angeordnete elastische Matte weitgehend die erforderliche vertikale Schieneneinsenkung übernimmt und daher die Schiene durch die steifen, äußeren Schienenauflager fest mit dem Schwellenrahmen verbunden und gegen Kippen gesichert werden kann. Die vertikale Schienenverformung zwischen den Schienenbefestigungen bleibt dank des weichen mittleren Schienenauflagers nahezu unbehindert.This ensures that the elastic arranged under the threshold frame Mat largely takes on the required vertical rail countersink and therefore the rail is fixed by the rigid, outer rail supports can be connected to the sleeper frame and secured against tipping. The vertical rail deformation between the rail fastenings remains almost unhindered thanks to the soft middle rail support.
Die Vorpressung im mittleren Schienenauflager kann abhängig von dessen Steifigkeit und Vorpresshöhe so eingestellt werden, dass die vertikale Schieneneinsenkung unter der Radlast sowohl in der Rahmenmitte als auch in den Schienenbefestigungen gleich groß wird und auf diese Weise einer kontinuierlichen Schienenauflagerung entspricht. Damit wird auch die Schwingungsdämpfung des Systems weiter verbessert.The pre-compression in the middle rail support can depend on its rigidity and pre-press height are adjusted so that the vertical rail countersink under the wheel load both in the center of the frame and in the rail fastenings becomes the same size and in this way a continuous one Rail support corresponds. The vibration damping of the Systems further improved.
Nach einer anderen Ausführungsform der Erfindung ist jeweils unter einer Schienenachse ein Längsträger vorgesehen. Hierdurch kann eine kontinuierliche oder quasi-kontinuierliche Lagerung der Schiene auf einfache Weise erreicht werden, ohne beispielsweise die Querschwellen sehr eng aufeinander vorsehen zu müssen. Die Anzahl der Querschwellen kann insbesondere auf zwei reduziert werden. An dieser Stelle sei darauf hingewiesen, dass unter einer quasikontinuierlichen Lagerung der Schiene eine Lagerung in eng aufeinander liegenden Punkten oder Bereichen zu verstehen ist, ohne dass in den Bereichen, in denen keine Lagerung vorgesehen ist, eine von der gewünschten Biegelinie der Schiene unter Last wesentliche Abweichung erzeugt wird.According to another embodiment of the invention is in each case one Rail axis provided a side member. This can create a continuous or quasi-continuous storage of the rail achieved in a simple manner are, for example, without providing the cross sleepers very closely to one another to have to. The number of cross sleepers can in particular be reduced to two become. At this point it should be noted that under a quasi-continuous Storage of the rail is a storage in close to each other Points or areas is to be understood without being in the areas in which no storage is provided, one of the desired bending line Rail generates significant deviation under load.
Die Position der äußeren Schienenauflager und/oder der Schienenbefestigungen ist so gewählt, dass die Mittelebene der Schienenbefestigungen quer zum Verlauf der Schienen einen Abstand kleiner gleich 15 cm, vorzugsweise kleiner gleich 10 cm von der äußeren Begrenzung des Schwellenrahmens in Längsrichtung aufweist Bei entsprechender Abmessung der Querschwellen in Längsrichtung kann eine bezüglich dieser Abmessung mittige Anordnung dieser Elemente erfolgen.The position of the outer rail supports and / or the rail fastenings is chosen so that the central plane of the rail fastenings is transverse to the course the rails have a distance of less than or equal to 15 cm, preferably less than or equal to 10 cm from the outer boundary of the threshold frame in the longitudinal direction With appropriate dimensions of the cross sleepers in the longitudinal direction a central arrangement of these elements with respect to this dimension.
Nach der bevorzugten Ausführungsform der Erfindung sind die Querschwellen. und der eine Längsträger einstückig, vorzugsweise als Spannbetonelement ausgebildet. Hierdurch ergibt sich eine einfache, rationelle Möglichkeit der Herstellung.According to the preferred embodiment of the invention, the cross sleepers are. and the one longitudinal beam in one piece, preferably as a prestressed concrete element educated. This results in a simple, rational possibility the production.
Dabei kann der Schwellenrahmen insgesamt als Spannbetonteil ausgebildet sein oder es können als normale Betonteile oder Spannbetonteile hergestellte äußere Bereiche der Querschwelien (und ggf. der Längsträger) mit einer Verbindungsstange in Form eines Metallprofils verbunden sein.The threshold frame can be designed as a prestressed concrete part or it can be outer manufactured as normal concrete parts or prestressed concrete parts Areas of the cross passages (and possibly the side members) with a connecting rod be connected in the form of a metal profile.
Nach einer Ausführungsform der Erfindung werden als Bewehrung des Schwellenrahmens Spannelemente verwendet, die an den Stirnseiten einer Querschwelle verankert sind. Die Spannelemente sind mit Bögen von dieser Querschwelle über einen Längsträger zu einer zweiten Querschwelle geführt und an deren Stirnseiten verankert. Hierdurch ergibt sich der Vorteil, dass das Aufbringen der Vorspannung von lediglich zwei einander gegenüberliegenden Seiten des Rahmens erfolgen kann und in einem Arbeitsgang sowohl eine Vorspannung in Längs- als auch in Querrichtung erzeugt werden kann.According to one embodiment of the invention, the reinforcement of the threshold frame Clamping elements used on the end faces of a cross sleeper are anchored. The tensioning elements are arched from this cross sleeper led a side member to a second cross sleeper and on the end faces anchored. This has the advantage that the preload is applied from only two opposite sides of the frame can take place and in one operation both a prestress in longitudinal and can also be generated in the transverse direction.
Dabei können mindestens zwei gegeneinander um 180° verdrehte U-förmige Spannelemente vorgesehen sein, deren Enden jeweils an einander gegenüberliegenden Stirnseiten zweier Querschwellen verankert sind. Die Bögen der Spannelemente können durch denselben Längsträger verlaufen oder bei zwei oder mehreren Längsträgern durch jeweils einen Längsträger, der näher an denjenigen Stirnseiten der Querschwellen liegt, in denen die Enden des jeweils anderen Spannelements verankert sind.In this case, at least two U-shaped rotated against each other by 180 ° Clamping elements may be provided, the ends of which are respectively opposite one another End faces of two cross sleepers are anchored. The arches of the tensioning elements can run through the same side member or with two or more Side members by one side member each, which is closer to that End faces of the cross sleepers, in which the ends of each other Clamping element are anchored.
Die Spannelemente können jedoch auch im Wesentlichen Z-förmig ausgebildet sein, wobei die Enden eines Spannelements an jeweils gegenüberliegenden Enden verschiedener Querschwellen verankert sind. Bei einem Schwellenrahmen, der mindestens zwei Längsträger aufweist, können dabei mindestens vier Z-förmige Spannelemente vorgesehen sind, wobei sich jeweils zwei Z-förmige Spannelemente in jeweils dem selben Längsträger kreuzen.However, the tensioning elements can also be essentially Z-shaped be, the ends of a tensioning element at respectively opposite ends different cross ties are anchored. With a threshold frame, which has at least two longitudinal beams, at least four Z-shaped ones Clamping elements are provided, with two Z-shaped ones Cross the clamping elements in the same side member.
Zur Herstellung eines derartigen Schwellenrahmen kann dieser zunächst mit Spannfugen in den Längsträgern hergestellt werden. Die Spannelemente werden dann durch Fugenaufweitung der Spannfügen vorgespannt. Die Spannfugen werden schließlich mit einem geeigneten erhärtbaren Baustoff geschlossen, so dass sich eine form- und kraflschlüssige Verbindung in den Spannfugen ergibt. Selbstverständlich kann auch eine andersartige geeignete Fixierung der vorgespannten Stellung des Schwellenrahmens vorgenommen werden.To manufacture such a threshold frame, it can first be used Expansion joints are made in the side members. The tensioning elements are then prestressed by expanding the joints. The expansion joints are finally closed with a suitable hardenable building material so that there is a positive and non-positive connection in the expansion joints. Of course, a different type of suitable fixation of the prestressed can also be used Position of the threshold frame can be made.

Der in Figur 1 schematisch dargestellte Ausschnitt einer Gleisanlage in Draufsicht
zeigt eine Ausführungsform eines Schwellenrahmens mit zwei Querschwellen
1, die mit zwei Längsträgern 2 zu einem vorzugsweise einstückigen
Bauteil verbunden sind. Die Ausbildung von Schienenbefestigungen 3 mit dazugehörigen
äußeren Schienenauflagern 4 entsprechen dem bekannten Stand der
Technik.The section of a track system shown schematically in Figure 1 in plan view
shows an embodiment of a threshold frame with two
Durch das Vorsehen der Schienenbefestigungen 3 auf den die äußere Begrenzung
des Schwellenrahmens bildenden Querschwellen wird erreicht, dass jeweils benachbarte
Schwellenrahmen mit nur einem relativ geringen Spalt aneinander
gereiht werden können und somit die Schienen 6 an den Schnittstellen zwischen
zwei Schwellenrahmen mit nur geringem Abstand voneinander fixierbar sind.
Dies verbessert das Aufnehmen von Querkräften, insbesondere von Kräften vertikal
zum Verlauf der Schienen bei einer Belastung durch die Räder eines schienengebundenen
Fahrzeugs (in geringerem Maße treten selbstverständlich auch
Querkräfte in der durch die Schienen 6 gebildeten Ebene auf, beispielsweise in
Kurven). Hierdurch ergibt sich bei einer Belastung der Schienen eine geringere
Abweichung vom gewünschten Verlauf der praktisch unvermeidbaren Durchbiegung
an den Schnittstellen benachbarter Schwellenrahmen.By providing the
Die Beschränkung der Rahmengröße in Gleislängsrichtung auf nur zwei nahe der
Querfuge angeordnete Schienenbefestigungen 3 mit den zwei äußeren Schienenauflagern
4 hat den Vorteil, dass die Rahmen ohne Zwang der unter der Radlast
auftretenden Schieneneinsenkung folgen können und an den Querfugen nur geringe
Einsenkungsdifferenzen auftreten. Dadurch bleiben auch die in der Querfuge
zu übertragenden Querkräfte so gering, dass sie über die Schienen 6 ohne
wesentliche Zusatzbeanspruchung übertragen werden. Eine zusätzliche Verbindung
in der Querfuge ist damit nicht mehr erforderlich.The limitation of the frame size in the longitudinal direction to only two near the

Das mittlere Schienenauflager 5 zwischen den äußeren Schienenauflagern 4 hat
die Aufgabe, einerseits die weiter als üblich freitragende Schiene 6 gegen die

dämpfen.The
Da die Schiene 6 zwischen den äußeren Schienenauflagern 4 in Rahmenmitte
sich sowohl nach unten infolge der direkt darüber befindlichen Radlast als auch
nach oben infolge der sogenannten Abhebewelle durchbiegt, muss das mittlere
Schienenauflager 5 diesen Bewegungen ohne Ablösung von der Schiene 6 folgen
können. Since the
Das wird dadurch erreicht, dass die Oberfläche des mittleren Schienenauflagers 5
vor der Schienenmontage deutlich, vorzugsweise zwischen 2 bis 5 mm, höher
liegt als die Oberfläche der äußeren Schienenaußager 4. Mit dem Auflegen der
Schiene 6 und dem Anspannen der elastischen Schienenbefestigungen 3 wird das
mittlere Schienenauflager 5 bis zur Höhe der äußeren Schienenauflager 4 zusammengedrückt
und erhält dadurch eine Druckvorspannung, die auch bei einer
Schienendurchbiegung nach oben in der Größenordnung von 0,1 mm erhalten.
bleibt.This is achieved in that the surface of the
