Abstract

The invention relates to a railway sleeper (12) consisting of rails placed on top of a bed of road metal. The underside of said sleeper is provided with a plastic deformable coating (22) increasing the stability of the track layer and reducing damage to the bed of road metal.

Description

Die Erfindung betrifft eine Querschwelle für Eisenbahngleise aus Beton, bewehrtem Beton oder Stahl, wie sie im Zusammenhang mit auf einem Schotterbett aufliegenden Gleisrosten im Eisenbahnoberbau verwendet werden.The invention relates to a cross tie for railway tracks made of concrete, reinforced concrete or steel, such as those related to one Ballast bed overlying rail gratings can be used in the railway superstructure.

Die Querschwelle als Bauelement im Eisenbahnoberbau nimmt die von den Verkehrslasten ausgehenden Kräfte über die Schiene und die Zwischenlagen mit den Verspannungselementen in den Stützpunkten der Schwellenauflager auf und die eingeleiteten Kräfte werden an das darunterliegende Schottergerüst lastverteilend abgeleitet und an den Unterbau bzw. Untergrund weitergeleitet.The cross sleeper as a component in the railway superstructure takes that of the forces arising from the traffic loads via the rail and the intermediate layers with the tensioning elements in the bases of the sleeper supports and the forces introduced are applied to the underlying ballast structure derived to distribute the load and passed on to the substructure or subsurface.

Seit Beginn des Eisenbahnzeitalters im vergangenen Jahrhundert werden als Querschwellen Holzschwellen verwendet. In der Zeit der Industrialisierung und als Barometer der Stahlindustrie wurden auch Stahlschwellen produziert und eingebaut, in neuerer Zeit auch als "Y-Schwelle". Seit den 50er Jahren dieses Jahrhunderts wurden zunehmend Spannbetonschwellen verwendet, die sich derzeit als Stand der Technik durchgesetzt haben.Since the beginning of the railway age in the past century wooden sleepers are used as cross sleepers. In the time of Industrialization and as a barometer of the steel industry were also Steel sleepers produced and installed, more recently also as "Y-sleepers". Since the 50s of this century have been increasing Prestressed concrete sleepers are used, which are currently state of the art have prevailed.

Die u.a. aus ökologischen Gründen kaum noch verwendete Holzschwelle hatte unter anderem den Vorteil, als "elastisch" zu gelten. Einer der Gründe dafür ist die Verzahnung der vergleichsweise weichen Holzschwellenunterseite mit dem Hartsteinschotter.The u.a. hardly used anymore for ecological reasons Among other things, wooden sleepers had the advantage of being considered "elastic". One of The reason for this is the interlocking of the comparatively soft Wooden sleeper base with the hard stone gravel.

Demgegenüber haben die Betonschwelle und die in diesem Zusammenhang vergleichbare Stahlschwelle den Nachteil, daß, im Gegensatz zur Holzschwelle, an der Auflagerfläche der Schwelle auf dem Schotter zwei unelastische Materialien zusammentreffen, so daß die oben erwähnte Verzahnung nicht möglich ist, so daß die Aufnahme von Längs- und Querkräften durch das Schotterbett verringert wird. Des weiteren führen die harten, unelastischen Kontaktstellen zwischen Schotter und Schwelle bei Überbeanspruchung zu Beschädigungen bzw. Zerstörungen der Schwelle oder des Schotters.In contrast, the concrete threshold and those in it Similar steel tie the disadvantage that, in contrast to Wooden sleeper, on the support surface of the sleeper on the gravel two inelastic materials meet, so that the above-mentioned toothing is not possible, so that the absorption of longitudinal and transverse forces by the Ballast bed is reduced. Furthermore, the hard, inelastic lead Contact points between ballast and threshold in the event of overuse Damage or destruction of the sleeper or ballast.

Um eine Überbeanspruchung des Schotters insbesondere bei Schnell-Fahr-Strecken zu vermeiden, wurde bereits vorgeschlagen, die Schwellenunterseite mit einem elastischen, polymeren Material zu beschichten, um eine Abfederung zu erreichen und damit eine Entlastung der Schotterpressung zu erzielen. Durch Verwendung einer solchen elastischen Zwischenschicht zwischen Schotter und Betonschwelle kann zwar das Schotterbett geschont werden, andererseits jedoch werden hierdurch die Längs- und Querverschiebungswiderstandskräfte erheblich gesenkt, so daß die Lagestabilität solcher Gleise noch geringer ist als diejenige von Gleisen, bei denen die Betonschwellen unmittelbar auf dem Schotterbett aufliegen.To overuse the ballast, especially on high-speed routes to avoid, it has already been suggested that To coat the underside of the sleeper with an elastic, polymeric material to achieve a cushioning and thus relieve the pressure on the ballast achieve. By using such an elastic intermediate layer between Ballast and concrete sleeper can be spared the ballast bed, on the other hand, however, the longitudinal and Transverse displacement resistance forces significantly reduced, so that the position stability such tracks is even less than that of tracks where the Concrete sleepers rest directly on the ballast bed.

Der Erfindung liegt daher in erster Linie die Aufgabe zugrunde, eine Schwelle zu schaffen, mit der die Lagestabilität des Gleises erhöht werden kann und gleichzeitig eine Beschädigung des Schotterbettes vermieden wird.The invention is therefore primarily based on the object To create a threshold with which the positional stability of the track can be increased and damage to the ballast bed is avoided at the same time.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Querschwelle an ihrer Unterseite insbesondere im Bereich ihrer Auflager mit einer plastisch verformbaren Beschichtung versehen ist.This object is achieved in that the Cross threshold on its underside, in particular in the area of its supports with a plastically deformable coating is provided.

Aufgrund der plastisch verformbaren Beschichtung der Schwellenunterseite wird aufgrund der plastischen Verformung der Beschichtung eine "Verzahnung" der Schwelle mit dem Schotter erzielt, wodurch zum einen der Querverschiebewiderstand und der Längsverschiebewiderstand des Gleisrosts deutlich erhöht wird und damit die Lagestabilität des Gleises wesentlich verbessert wird. Weiterhin wird hierdurch erreicht, daß einerseits Spitzendrücke abgebaut und Kantenpressungen verkleinert werden und andererseits, daß die Kontaktfläche zwischen Schotter und Schwelle vergrößert wird, so daß die Flächenpressungen gegenüber dem Stand der Technik verringert werden und Materialzerstörungen reduziert bzw. ausgeschlossen werden. Schließlich ist auch die mit der Beschichtung erzielte "Weichheit" des Kontaktbereichs zwischen Schotter und Schwelle materialschonend.Due to the plastically deformable coating of the The underside of the threshold is due to the plastic deformation of the coating achieved a "interlocking" of the threshold with the ballast, which on the one hand Transverse sliding resistance and the longitudinal sliding resistance of the track grate is significantly increased and thus the positional stability of the track is significantly improved becomes. Furthermore, this ensures that, on the one hand, peak pressures are reduced and Edge pressures are reduced and on the other hand that the contact area between the ballast and threshold is increased so that the surface pressures be reduced compared to the prior art and material destruction be reduced or excluded. After all, the one with the Coating achieved "softness" of the contact area between ballast and Threshold gentle on materials.

In bevorzugter Weiterbildung der Erfindung kann die plastisch deformierbare Beschichtung im wesentlichen aus einem Teer-/Asphaltgemisch bestehen, was eine besonders kostengünstige Lösung ist. In alternativer Weise kann die Beschichtung im wesentlichen aus einem Kunststoff, aus Holzbeton, aus Holz oder aus Holzspänen bestehen.In a preferred development of the invention, the plastic deformable coating consisting essentially of a tar / asphalt mixture exist, which is a particularly inexpensive solution. Alternatively the coating can essentially consist of a plastic, of wood concrete Made of wood or wood chips.

Bereits aus Kostengründen kann es zweckmäßig sein, die plastisch deformierbare Beschichtung ausschließlich im Bereich des Auflagers der Querschwellen auszubilden, so daß die auflagerfreien Zonen unbeschichtet bleiben.For cost reasons alone, it can be useful to use plastic deformable coating only in the area of the support Form cross sleepers so that the bearing-free zones are uncoated stay.

Die Dicke der Beschichtung kann vergleichsweise dünn sein, d.h. unter 10mm liegen und kann insbesondere etwa 5mm betragen. Weiterhin kann die Unterseite der Beschichtung profiliert sein, um eine noch bessere Verankerung der Querschwellen auf dem Schotterbett zu erzielen.The thickness of the coating can be comparatively thin, i.e. under 10mm lie and can in particular be about 5mm. Furthermore, the Underside of the coating to be profiled in order to anchor the Achieve cross sleepers on the ballast bed.

Obwohl die erfindungsgemäße Beschichtung der Querschwellen gegebenenfalls auch nachträglich an den Schwellen angebracht werden kann, wird es bevorzugt, das Aufbringen der Beschichtung in den Fertigungsprozeß der Betonschwellen zu integrieren, um den bestmöglichen Verbund sicherzustellen. Hierzu kann die Beschichtung insbesondere als abschließender Arbeitsgang beim Gießen der Schwelle auf die entsprechenden Bereiche der Schwellenunterseite aufgebracht werden. In alternativer Weise könnte die Beschichtung auch nachträglich an der Schwellenunterseite angeklebt werden.Although the coating of the cross sleepers according to the invention can also be attached to the sleepers, if necessary it prefers to apply the coating in the manufacturing process of the Integrate concrete sleepers to ensure the best possible bond. For this purpose, the coating can be used in particular as a final operation Pour the threshold onto the corresponding areas of the underside of the threshold be applied. Alternatively, the coating could also subsequently glued to the underside of the threshold.

Im folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. In der Zeichnung zeigen:

  • Figur 1 einen vertikalen Schnitt durch ein Gleis in einer Ebene parallel zu den Schienen,
  • Figur 2 eine Draufsicht auf das Gleis gemäß Figur 1,
  • Figur 3 einen horizontalen Schnitt durch das Gleis gemäß Figur 1 senkrecht zur Längsrichtung der Schienen, und
  • Figur 4 eine vergrößerte Schnittansicht im Bereich einer Schwelle.
    • An exemplary embodiment of the invention is explained in more detail below with reference to the drawing. The drawing shows:
  • 1 shows a vertical section through a track in a plane parallel to the rails,
  • FIG. 2 shows a top view of the track according to FIG. 1,
  • 3 shows a horizontal section through the track according to FIG. 1 perpendicular to the longitudinal direction of the rails, and
  • Figure 4 is an enlarged sectional view in the area of a threshold.

    • In den Figuren ist mit der Bezugsziffer 10 ein Schotterbett, mit der Bezugsziffer 12 im Schotterbett angeordnete Querschwellen, mit der Bezugsziffer 14 auf den Querschwellen angeordnete Schienen und mit der Bezugsziffer 16 ein auf den Schienen geführtes Rad bezeichnet. Zwischen Schiene 14 und Querschwellen 12 sind die üblichen Zwischenlagen 18 angeordnet. Das Schotterbett 10 liegt auf einem Planum 20 auf. Insoweit entspricht dieser Aufbau eines Eisenbahngleises dem konventionellen Aufbau und bedarf keiner näheren Erläuterung,In the figures, reference number 10 is a ballast bed with which Reference number 12 transverse sleepers arranged in the ballast bed, with the reference number 14 rails arranged on the cross sleepers and with the reference number 16 Inscribed wheel guided on the rails. Between rail 14 and Transverse sleepers 12, the usual intermediate layers 18 are arranged. The Ballast bed 10 lies on a formation 20. In this respect, this structure corresponds of a railroad track the conventional structure and requires no closer Explanation,

    An den Unterseiten der Querschwellen 12 sind plastisch verformbare Beschichtungen 22 ausgebildet, und zwar, wie aus Figuren 2 und 3 erkennbar ist, derart, daß die auflagerfreien Bereiche 24 der Querschwellen 12 beschichtungsfrei sind. Anzumerken ist, daß die Schraffierungen in Figur 2 diejenigen Bereiche der (in Figur 2 nicht sichtbaren) Schwellenunterseite kennzeichnen sollen, an denen eine Beschichtung vorgesehen ist. Die Pfeile 26 und 28 in den Figuren 1 bis 3 sollen die im Gleis auftretenden Quer- bzw. Längskräfte andeuten.On the undersides of the cross sleepers 12 are plastically deformable Coatings 22 formed, as can be seen from Figures 2 and 3, such that the bearing-free areas 24 of the cross sleepers 12 are coating-free are. It should be noted that the hatching in Figure 2 those areas of To mark (not visible in Figure 2) threshold underside on which a coating is provided. The arrows 26 and 28 in FIGS. 1 to 3 should indicate the transverse or longitudinal forces occurring in the track.

    Die Detaildarstellung gemäß Figur 4 verdeutlicht die Verzahnung der Steine des Schotterbetts mit der plastisch deformierbaren Beschichtung 22. Zum einen wird hieraus unmittelbar deutlich, daß die Verschiebekräfte aufgrund der Verzahnung deutlich zunehmen, zum anderen ist auch ohne weiteres erkennbar, daß die Kontaktfläche der Schwellenunterseite mit dem Schotterbett nunmehr stark vergrößert ist, so daß die zwischen den Kontaktflächen pro Flächeneinheit auftretenden Kräfte insgesamt deutlich reduziert werden.The detailed representation according to FIG. 4 illustrates the interlocking of the Stones of the ballast bed with the plastically deformable coating 22. Zum one is immediately clear from this that the displacement forces due to the Gearing increases significantly, on the other hand is also easily recognizable, that the contact surface of the threshold underside with the ballast bed is now strong is enlarged so that between the contact areas per unit area occurring forces can be significantly reduced overall.

    Die mit der Erfindung erzielten Vorteile liegen demnach insbesondere darin, daß

    • anstelle einer wie beim Stand der Technik vorhandenen punktuellen Kraftübertragung zwischen Schwelle und Schotter nunmehr eine flächenmäßige Kraftübertragung erfolgt,
    • Spitzendrücke auf einzelne Schottersteine abgebaut und die Kantenpressungen verkleinert werden,
    • hierdurch eine Zertrümmerung der Schottersteine bzw. eine Beschädigung der Betonschwelle vermieden wird, und
    • aufgrund der Verzahnung des Schotterbetts an der plastisch deformierbaren Beschichtung der Querschwellen eine Erhöhung der Längs- und Querverschiebewiderstände auftritt, wodurch die Lagestabilität des Gleises verbessert wird.
    The advantages achieved with the invention are therefore in particular that
    • Instead of a selective power transmission between the sleeper and ballast, as is the case in the prior art, there is now an areal power transmission,
    • Peak pressures are reduced to individual gravel stones and the edge pressures are reduced,
    • this prevents crushing of the ballast stones or damage to the concrete sleeper, and
    • Due to the interlocking of the ballast bed on the plastically deformable coating of the cross sleepers, an increase in the longitudinal and transverse displacement resistance occurs, which improves the positional stability of the track.
