Abstract

It is proposed to arrange crossbars (24) consisting of right-angled profiles in the ballast bed under steel sleepers (3) for railway tracks, the first flange of which profiles is welded with the base of the sleeper and the second flange of which projects perpendicular away from the base deep into the ballast bed. As a result, the lateral forces which occur on the passage of a train are absorbed by the rails and sleepers and a transverse displacement of the sleepers and of the entire track is prevented. For an optimum design of the crossbars, they can be used as a stacking aid during the transport of the steel sleepers which have been preassembled ready for laying at the manufacturer's, so that shipping timbers can be discarded. <IMAGE>

Description

Die Erfindung betrifft eine Stahlschwelle mit Lagesicherung für ein Bahngleis im Schotterbett.The invention relates to a steel sleeper with position securing for a railway track in the ballast bed.

Lagesicherung dieser Art erhöhen in Schotterbetten den Querverschiebewiderstand der Schwellen und der Gleisanlage insgesamt. Insbesondere in überhöhten Kurven eines Schienenstranges haltende Züge erzeugen im Gleiskörper erhebliche Querkräfte. Stahlschwellen mit ebener Sohle, also glatter Auflagefläche zum Schotterunterbau, bedürfen einer Lagesicherung.Positional security of this type increases the transverse displacement resistance of the sleepers and the track system as a whole in ballast beds. Trains stopping in excessive curves of a rail track generate considerable lateral forces in the track body. Steel sleepers with a flat sole, i.e. a smooth contact surface for the ballast substructure, require positional security.

Es ist bekannt ("Die Y-Stahlschwelle im Schotteroberbau", Der Eisenbahningenieur, 38 (1986) 3, S. 128/129 und DE-A1-35 21 673), an aus H-Profilen zusammengesetzten Y-Stahlschwellen den Querverschiebewiderstand durch unter jedes der drei Schwellenenden geschweißte Vierkantstähle noch weiter zu erhöhen, als er schon durch die Gabelform der Y-Schwelle von Natur aus ist. Derartige Knüppel treiben allerdings das Gewicht und damit die Kosten der Schwelle, ohne den Widerstand gegen Querverschiebung entscheidend zu erhöhen. Außerdem liegen die beiden Schweißnähte des Querriegels sehr eng zusammen, so daß bei der Fertigung Maßnahmen gegen Verzug der Stahlschwellen aufgrund großen Wärmeeinbringens getroffen werden müssen.It is known ("Die Y-Stahlschwelle im Schotteroberbau", Der Eisenbahningenieur, 38 (1986) 3, pp. 128/129 and DE-A1-35 21 673), on Y-steel sleepers composed of H-profiles, the transverse displacement resistance by below to increase each of the three sleeper ends of welded square steels even more than it is inherently due to the fork shape of the Y sleeper. However, such sticks drive the weight and thus the cost of the threshold without significantly increasing the resistance to lateral displacement. In addition, the two welds of the crossbar are very close together, so that measures against warping of the steel sleepers due to large amounts of heat must be taken during manufacture.

Aus der GB-A-2012338 ist ebenfalls eine Y-förmige Stahlschwelle bekannt, deren Schwellenenden aus parallelen Doppel-T-Trägern bestehen und die durch aufgeschweißte Rippenplatten zur Schienenführung miteinander verbunden sein können. Derartige Schwellen können zur Lagesicherung parallel auf mit Gleisbett verankerten Profilen verschraubt werden, die einseitig oder beidseits parallel zu den Schienen neben den Schienenführungen angeordnet sind. Es handelt sich dabei offensichtlich um langgestreckte Profile an denen mehrere Schwellenenden befestigt sind. Die Schwelle kann mit ihrer Lagesicherung nicht werkstattmäßig vorgefertigt werden. Eine Lagesicherung während des Transportes der Schwellen ist nicht offenbart.From GB-A-2012338 a Y-shaped steel sleeper is also known, the sleeper ends of which parallel double T-beams exist and can be connected to each other by welded ribbed plates for rail guidance. Such sleepers can be screwed in parallel to secure the position on profiles anchored to the track bed, which are arranged on one or both sides parallel to the rails next to the rail guides. These are obviously elongated profiles to which several threshold ends are attached. The threshold cannot be prefabricated in the workshop with its position securing device. A securing of the position during the transport of the sleepers is not disclosed.

Von daher ist es Aufgabe der vorliegenden Erfindung, eine dauerhafte und hochwirksame Lagesicherung gegen Querverschiebung der Schwelle und des Schienenstranges mit wirtschaftlicher fabrikseitiger Fertigungsmöglichkeit vorzuschlagen.It is therefore an object of the present invention to propose a permanent and highly effective positional safeguard against transverse displacement of the threshold and the rail track with an economical manufacturing possibility on the factory side.

Die Aufgabe wird durch die im Anspruch 1 genannten Merkmale gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen erfaßt.The object is achieved by the features mentioned in claim 1. Advantageous embodiments of the invention are covered in the subclaims.

Die erfindungsgemäße Ausgestaltung der Querriegel für den erhöhten Verschiebewiderstand der Schwellen als gewinkelte Profile hat eine ganze Reihe von Vorteilen. Erstens ist der Widerstand überproportional größer als die Gewichtszunahme der Schwelle, zweitens liegen die Schweißnähte unter der Sohle weiter auseinander, und somit ist kein Wärmeverzug der Schwelle zu erwarten, drittens ist eine Stützwirkung gegen Verbiegen des senkrechten Flanschabschnittes durch den verscheißten Flansch gegeben, viertens ergibt sich eine längere und damit sicherere Schweißnaht, wenn der Flansch an mindestens zwei Seiten mit der Sohle der Schwelle verschweißt wird, und fünftens ist der senkrechte Steg, d. h. der zweite Flansch, kein Hindernis beim Stopfen der Schwelle.The design of the crossbars according to the invention for the increased displacement resistance of the sleepers as angled profiles has a number of advantages. Firstly, the resistance is disproportionately greater than the weight increase of the threshold, secondly, the weld seams under the sole are further apart, and therefore no heat distortion of the threshold is to be expected, thirdly, there is a supporting effect against bending of the vertical flange section by the welded flange, fourthly a longer and therefore safer weld, if the flange is welded to the base of the sleeper on at least two sides, and fifth, the vertical web, i. H. the second flange, no obstacle when stuffing the threshold.

Eine optimale Ausnutzung der Erfindung ist gegeben, wenn für die Lagesicherung ein gewinkeltes Profil in T-Form gewählt wird, das handelsüblich erhältlich ist oder aus einem Mitte Steg quer getrennten H-Normalträger erzeugt werden kann. Die Stützwirkung des Steges durch den verschweißten Flansch wirkt bei Querverschiebekräften aus beiden Seitenrichtungen.An optimal use of the invention is given if an angled profile in T-shape is selected for securing the position, which is commercially available or can be produced from a center web cross-separated H-normal beam. The support effect of the web due to the welded flange acts with transverse displacement forces from both side directions.

Ähnliche Vorteile hat ein Querriegel in L-Form. Die volle Wirkung, insbesondere gegen das am senkrechten Flansch angreifende Kippmoment bei Seitenkräften, wird erreicht, wenn diese Querriegel spiegelbildlich zur Gleismitte angeordnet sind. Je nach Kraftrichtung kann einer der Querriegel jeweils die volle Stützwirkung des verscheißten Flansches einbringen.
Im übrigen ergibt sich für L-Profile und T-Profile als Querriegel ein weiterer vorteilhafter Wirkmechanismus:
genau die Schottersteine, die bei Querverschiebung der Schwelle durch den sinusförmigen Zuglauf auf den Schienen und damit einer Querverschiebung des senkrechten Flansches, Seitenkräften durch den senkrechten Flansch ausgesetzt sind, werden gleichzeitig, durch die Gewichtseinleitung vom Zug über Schiene, Schwelle und den an der Sohle der Schwelle verschweißten Flansch, einer erheblich senkrechten Pressung unterworfen, wodurch wiederum die Reibkräfte einer Relativbewegung zwischen Schotter und verschweißtem Flansch entgegenwirken.An L-shaped crossbar has similar advantages. The full effect, especially against the tilting moment of lateral forces acting on the vertical flange, is achieved if these crossbars are arranged in mirror image to the middle of the track. Depending on the direction of force, one of the crossbars can provide the full support of the welded flange.
There is also another advantageous mechanism of action for L-profiles and T-profiles as crossbars:
Exactly the ballast stones, which are exposed to lateral forces due to the vertical flange when the threshold is shifted by the sinusoidal train running on the rails and thus to a transverse shift of the vertical flange, are simultaneously, by the weight transfer from the train via rail, threshold and at the bottom of the Threshold welded flange, subjected to a considerably vertical pressure, which in turn counteracts the frictional forces of a relative movement between ballast and welded flange.

Der senkrechte Steg/Flansch des gewinkelten Profiles soll genau unter dem Auflagebereich der Eisenbahnschiene liegen und dabei eine größere Höhe als die Schienenbefestigungselemente wie Seitenführungsplatten, Schrauben und/oder Federn haben.The vertical web / flange of the angled profile should lie exactly below the support area of the railroad track and should have a greater height than the rail fastening elements such as side guide plates, screws and / or springs.

Unterstellt wird, daß die komplette Schwelle einschließlich Querriegel und Schienenauflager sowie Befestigungsteile im Herstellerwerk so vormontiert werden, daß auf der Eisenbahntrasse nur noch die Schienen auf den verlegten Schwellen justiert und geklemmt werden müssen. Dazu bedurfte es bisher erheblicher Mengen von Verladehölzern zum Stapeln von Schwellen auf den Transportwagen. Damit die Befestigungselemente nicht belastet werden. Die vorliegende Erfindung ermöglicht jetzt ein Verladen ohne Zwischenhölzer. Dies ist ein erheblicher wirtschaftlicher Vorteil. Die senkrechten Flansche der Querriegel aufeinander gestapelter Schwellen liegen während des Transportes der Schwellen genau an den Stellen, an denen später der Schienenfuß sich in der Schienenführung auf der Schwelle seitlich abstützt.It is assumed that the complete sleeper including crossbars and rail supports as well as fastening parts are preassembled in the manufacturing plant in such a way that only the rails on the installed sleepers have to be adjusted and clamped on the railway line. So far, this has required considerable amounts of loading timber for stacking sleepers on the transport wagon. So that the fasteners are not loaded. The present invention now enables loading without intermediate timbers. This is a significant economic advantage. During the transport of the sleepers, the vertical flanges of the crossbars of stacked sleepers lie exactly at the points at which the rail foot is laterally supported in the rail guide on the sleepers.

Anhand schematischer Zeichnungen soll die Erfindung näher erläutert werden.The invention will be explained in more detail with the aid of schematic drawings.

Auf einer aus zwei Doppel-T-Trägern 16, 17 gebildeten Stahlschwelle ist eine Schienenführung 15 durch Schweißnähte 7 fixiert (Fig. 1).
Die 140 mm breiten Flansche 18 bzw. 11 der 95 mm hohen Träger 16 bzw. 17 sind mit 40 mm Abstand zueinander angeordnet; sie bilden so in Verbindung mit der Schienenführung 15 ein Doppelauflager für eine Schiene 13 (Fig. 2), deren Schienenfuß 14 auf Plastikunterlage 5 elektrisch isolierend gelagert ist. Die Verspannung des Schienenfußes 14 erfolgt durch einen Federbügel 4, der sich einerseits in Bohrung 21 und an Schulter 22 der Schienenführung 15 und andererseits auf Isolierrippe 20, elektrisch isoliert zum Schienenfuß 14, federnd abstützt.A rail guide 15 is fixed by weld seams 7 on a steel tie formed from two double-T beams 16, 17 (FIG. 1).
The 140 mm wide flanges 18 and 11 of the 95 mm high beams 16 and 17 are spaced 40 mm apart; in connection with the rail guide 15, they thus form a double support for a rail 13 (FIG. 2), the rail foot 14 of which is electrically insulated on a plastic base 5. The rail foot 14 is braced by a spring clip 4, which is supported on the one hand in bore 21 and on shoulder 22 of the rail guide 15 and on the other hand on insulating rib 20, electrically insulated from the rail foot 14.

Fig. 1 zeigt ein unter den Sohlen der Flansche 19 bzw. 12 der Träger 16 bzw. 17 verschweißtes T-Profil 23, dessen 95 mm hoher Steg 8 senkrecht nach unten gerichtet ist. Der 90 mm breite Flansch 9 des aus einem Mitte Steg geteilten H-Normalträger von 200 mm Höhe gewonnenen T-Profils 23 ist durch Schweißnaht 10 an den Enden des Flansches 9 fest mit der Stahlschwelle verbunden. Dieser Schwellentyp mit dem als Querriegel fungierenden T-Profil 23 kann auch für eine nicht dargestellte alternative Schienenbefestigung verwendet werden. Dabei kann eine Schwellenschraube durch die Lücke zwischen den Flanschen 18 bzw. 11 und 19 bzw. 12 hindurchgeführt werden und in ein in Flansch 9 des T-Profils 23 gebohrtes Gewindeloch oder eine aufgeschweißte Mutter geschraubt werden.1 shows a T-profile 23 welded under the soles of the flanges 19 and 12 of the supports 16 and 17, the 95 mm high web 8 of which is directed vertically downwards. The 90 mm wide flange 9 of the T-profile 23, which is obtained from a center web and is 200 mm high, is firmly connected to the steel sleeper by a weld seam 10 at the ends of the flange 9. This type of threshold with the T-profile 23 acting as a crossbar can also be used for an alternative rail fastening, not shown. In this case, a sleeper screw can be passed through the gap between the flanges 18 or 11 and 19 or 12 and screwed into a threaded hole drilled in flange 9 of the T-profile 23 or a welded nut.

Fig. 2 zeigt in Seitenansicht eine Stahlschwelle 1 mit Träger 17, die mit der Sohle des Flansches 12 auf dem Schotter 6 ruht. Unter der Sohle verbindet Schweißnaht 10 den ersten Flansch 9 des T-Profils mit dem Flansch 12 der Schwelle, während der zweite Flansch des Profils - Steg 8 - tief in den Schotter 6 taucht. Während die durch einen Zug entstehende Gewichtsbelastung c über das Rad 28, die Schiene 13 und die Stahlschwelle 1 auf Schotter 6 übertragen wird, versuchen die durch sinusförmiges seitliches Verlaufen der Radsätze wahrend der Zugfahrt und dadurch von Radkranz 29 über den Kopf der Schiene 3 seitlich eingeleiteten Kräfte die Stahlschwelle 1 abwechselnd in die Pfeilrichtung a bzw. b zu verschieben. Dies verhindert der Steg 8 des T-Profils durch seine Lage in gepreßtem Schotter 6.
Die Fig. 2 zeigt weiterhin, daß die Schweißnähte 7 für die Befestigung der Schienenführung 15 auf dem Flansch 11 ziemlich genau über den Schweißnähten 10 des unter der Sohle des Flansches 12 befestigten Flansches 9 des T-Profils liegen. Dadurch entsteht kein Verzug des Trägers 17 durch Wärmeeinbringen beim Schweißen.Fig. 2 shows a side view of a steel sleeper 1 with support 17, which rests on the ballast 6 with the sole of the flange 12. Under the sole, weld seam 10 connects the first flange 9 of the T-profile to the flange 12 of the threshold, while the second flange of the profile - web 8 - plunges deep into the ballast 6. While the weight load c resulting from a train is transmitted to the ballast 6 via the wheel 28, the rail 13 and the steel sleeper 1, the sinusoidal lateral movement of the wheel sets during the train journey and thus from the wheel rim 29 over the head of the rail 3 leads to the side Forces to shift the steel sleeper 1 alternately in the direction of the arrow a or b. This is prevented by the web 8 of the T-profile due to its location in pressed ballast 6.
Fig. 2 also shows that the welds 7 for fastening the rail guide 15 on the flange 11 are almost exactly above the welds 10 of the flange 9 of the T-profile fastened under the sole of the flange 12. As a result, there is no distortion of the carrier 17 due to the introduction of heat during welding.

Fig. 3 zeigt als Querriegel unter den aufeinander gestapelten Schwellen 2, 3 ein ungleichschenkliges L-Profilstück 24 mit den Abmessungen 200 x 100 x 10 von 300 mm Länge, dessen breiter Flansch 25 am Ende und an der Winkelecke mit der Sohle der Schwellen 2,3 verschweißt ist. Dabei sind der Abstand "d" des kurzen zweiten Flansches 26 von den Kopfseiten der Schwelle und die Größe des Profils so gewählt, daß

  • a) möglichst viel Schotter zwischen dem Kopf der Schwelle 2,3 und und dem Flansch 26 liegt,
  • b) die Schweißnähte an Flansch 25 etwa unterhalb der Schweißnähte an der Schienenführung 15 liegen,
  • c) die Flansche 26 des Querriegels 24 unter Schwelle 3 beim Stapeln zwischen den jeweils zwei Schultern 22, 27 der Schienenführung 15 auf Schwelle 2, und zwar direkt neben der jeweiligen zur Gleisachse gelegenen Schulter 27 lagern und
  • d) der Flansch 26 höher als die Schultern 22, 27 der Schienenführung 15 ist.
3 shows as a cross bar under the sleepers 2, 3 stacked one on top of the other an isosceles L-profile piece 24 with the dimensions 200 x 100 x 10 and a length of 300 mm, the wide flange 25 of which at the end and at the corner with the sole of the sleepers 2, 3 is welded. The distance "d" of the short second flange 26 from the head sides of the threshold and the size of the profile are chosen so that
  • a) there is as much ballast as possible between the head of the sleeper 2, 3 and the flange 26,
  • b) the weld seams on flange 25 lie approximately below the weld seams on the rail guide 15,
  • c) the flanges 26 of the cross bar 24 under threshold 3 when stacking between the two shoulders 22, 27 of the rail guide 15 on threshold 2, directly next to the respective shoulder 27 to the track axis and store
  • d) the flange 26 is higher than the shoulders 22, 27 of the rail guide 15.

Dadurch wird eine optimale Vorteilskombination erreicht:

  • a) die die Querverschiebung der Schwelle 2, 3 hemmende Schottermenge wird so groß wie möglich,
  • b) die Schwelle 2,3 verzieht sich beim Schweißen der Anbauteile nicht,
  • c) die gestapelten Schwellen 2, 3 können beim Transport nicht seitlich verrutschen und
  • d) beim Stapeln werden keine Verladehölzer benötigt, und die Schienenführungen 15 werden nicht beschädigt.
This achieves an optimal combination of advantages:
  • a) the amount of ballast that inhibits the transverse displacement of threshold 2, 3 becomes as large as possible,
  • b) the threshold 2, 3 does not warp when welding the attachments,
  • c) the stacked sleepers 2, 3 cannot slip laterally during transport and
  • d) no loading sticks are required when stacking, and the rail guides 15 are not damaged.

Die erfindungsgemäßen Querriegel sind nicht auf die gezeigten T-Profile und L-Profile beschränkt. Außerdem können beispielsweise Wulstwinkelstähle oder ähnliches verwendet werden.The crossbars according to the invention are not limited to the T-profiles and L-profiles shown. In addition, bead angle steels or the like can be used, for example.
