Description

Die Erfindung betrifft eine Befestigung einer Y-förmigen Stahlschwelle nach dem Oberbegriff des Patentanspruchs 1. Im Gegensatz zu Beton -oder Holzschwellen, die im Schotterbett verlegt sind, ist es für Y-Schwellen auf einer festen Fahrbahn erforderlich, daß eine Befestigung der Schwellen mit dem Untergrund erfolgt, um die vom Fahrzeug übertragenen Kräfte sicher in den Untergrund zu leiten, ohne daß es zu einer Verschiebung des Gleisrostes kommt.The invention relates to a fastening of a Y-shaped steel sleeper according to the Preamble of claim 1. In contrast to concrete or wooden sleepers, which are laid in the ballast bed, it is for Y sleepers on a solid road required that the sleepers be fastened to the substrate in order to to transfer the forces transmitted by the vehicle safely into the ground without that there is a shift in the track grate.

Aus der DE 35 17 295 A1 ist eine Befestigung für eine Y-förmige Stahlschwelle mit dem festen Untergrund bekannt, bei der mit dem Untergrund verbundene Anker zum Einsatz kommen. Diese Ausbildung weist den Nachteil auf, daß sie sehr aufwendig ist und sich die Fertigstellung der festen Fahrbahn äußerst schwierig gestaltet, da bereits bei der Fertigung der festen Fahrbahn die Anker eingesetzt sein müssen. Weiterhin nachteilig ist eine Ausrichtung des Gleises sowohl bei der Erstverlegung als auch bei einer eventuellen Durcharbeitung nicht möglich. Diese Ausrichtung wird in die Schienenbefestigung verlegt, was die Schienenbefestigung verkompliziert.From DE 35 17 295 A1 there is a fastening for a Y-shaped steel sleeper the solid subsurface is known for the anchor connected to the subsurface are used. This training has the disadvantage that it is very expensive and the completion of the slab track is extremely difficult, since the anchors are already used in the manufacture of the solid track have to. Another disadvantage is an alignment of the track in both First laying as well as in case of a possible revision not possible. This Alignment is relocated to the rail fastener, which is the rail fastener complicated.

Der Erfindung liegt die Aufgabe zugrunde, eine Befestigung für Y-förmige Stahlschwellen auf einer festen Fahrbahn zu entwickeln, die ein Ausrichten des Gleises auch nach einer längeren Liegezeit ermöglicht.The invention has for its object a fastening for Y-shaped steel sleepers to develop on a solid carriageway that is aligning the track even after a long period of inactivity.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen sind in den Ansprüchen 2 bis 18 beschrieben. Die Patentansprüche 19 bis 22 zeigen Lösungen bezüglich des Verfahrens zum Befestigen von Y-Stahlschwellen auf einer festen Fahrbahn.This object is achieved by the features of claim 1. Advantageous training and further developments are described in claims 2 to 18. Claims 19 to 22 show solutions with regard to the method for fastening Y-steel sleepers on a solid road.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß mit einer einfachen und preiswerten Befestigung Y-förmige Stahlschwellen auf einer festen Fahrbahn befestigt werden können und daß der Gleisrost auch nach einer langen Liegezeit noch in einfacher Weise gegenüber dem Untergrund ausrichtbar ist. Mit den Merkmalen nach den Patentansprüchen 6 und 7 wird eine einfache Lösung aufgezeigt, das Gleis gegenüber dem Untergrund elektrisch zu isolieren.The advantages achieved by the invention are in particular that with a simple and inexpensive fastening Y-shaped steel sleepers on a fixed Roadway can be attached and that the track grate even after a long Lying time is still easy to align with the surface. With the features according to claims 6 and 7 is a simple solution demonstrated to electrically isolate the track from the ground.

Bei Einsatz der Verfahren nach den Patentansprüchen 19 bis 22 kann die feste Fahrbahn fertig hergestellt werden, ohne daß auf irgendwelche Befestigungsmittel Rücksicht genommen werden muß.When using the method according to claims 19 to 22, the fixed Roadway can be finished without any fasteners Must be taken into account.

Wie aus Fig. 1 ersichtlich, besteht eine Y-förmige Stahlschwelle aus mehreren über Riegel 1 miteinander verbundenen doppel-T-förmigen Stahlprofilen. Über nicht dargestellte Schienenbefestigungen sind Schienen 3 mit der Stahlschwelle verbunden, so daß sich ein fester Gleisrost bildet.As can be seen from Fig. 1, a Y-shaped steel sleeper consists of several over Bolt 1 interconnected double T-shaped steel profiles. About not shown Rail fasteners, rails 3 are connected to the steel sleeper, so that a solid track grate forms.

Wie aus Fig. 2 ersichtlich ist, liegen die Stahlschwellen mit dem Fußflansch 4 auf dem Untergrund 5 auf. Je nach Aufbau der das Gleis tragenden festen Fahrbahn besteht dieser Untergrund 5 aus Beton oder Asphalt. As can be seen from FIG. 2, the steel sleepers rest on the foot flange 4 the underground 5. Depending on the structure of the solid carriageway that supports the track this subsoil 5 consists of concrete or asphalt.

Auf das Gleis treten im Fahrbetrieb, aber auch durch die Längenänderung des Gleises bei Temperatureinfluß, Quer- und Längsschubkräfte auf, die die Gleislage verändern können. Von daher muß sichergestellt werden, daß das Gleis mit dem Untergrund verbunden wird. Dieses betrifft insbesondere den Einsatz von Schwellengleisen auf einer festen Fahrbahn. Bei der Ausbildung von Gleisen auf einem Schotterbett kann die Verbindung mit dem Untergrund durch das Einarbeiten der Schwellen in den Schotter erreicht werden.Step on the track while driving, but also by changing the length of the Track under the influence of temperature, shear and longitudinal shear forces on the track position can change. It must therefore be ensured that the track with the Is connected underground. This applies in particular to the use of sleeper tracks on a solid road. When forming tracks on one Ballast bed can be connected to the ground by incorporating the Thresholds can be reached in the gravel.

Nach der Erfindung ist vorgesehen, daß im Gegensatz zu den bisher bekannten Befestigungen keine formschlüssige Verbindung zwischen der Schwellenauflagefläche und dem Untergrund 5 vorgesehen ist. Vielmehr liegt der Fußflansch 4 der Profile 2 der Y-förmigen Stahlschwelle flach auf dem Untergrund 5 auf. Die Fixierung mit dem Untergrund erfolgt über einen fest mit dem Untergrund 5 verbundenen Anker 6. Im gezeigten Ausführungsbeispiel ist eine Bohrung 7 in den Untergrund eingebracht. Der Anker 6 ist dann über einen Dübel 8 mit dem Untergrund 5 verbunden. Das aus dem Untergrund herausragende obere Ende 9 des Ankers 6 weist ein Gewinde 10 auf, das im Zusammenwirken mit einer Mutter zum Verspannen 11 der Schwelle mit dem Untergrund 5 dient. Ein mit einer Bohrung 12 ausgebildetes Spannblech 13, das den jeweiligen Fußflansch 4 der Profile 2 übergreift, überträgt die Spannkraft des Ankers 6 auf die Stahlschwelle. Das Spannblech 13 kann elastisch bis zur Auflage auf den Untergrund 5 vorgespannt werden. Dadurch wird erreicht, daß es sich auf den nach außen verjüngenden Fußflansch 4 flächig auflegt. In Fig. 2 ist das Spannblech 13 in nicht oder gering verspannter Stellung gezeigt. Sofern die Y-förmigen Stahlschwellen gegenüber dem Untergrund isoliert ausgebildet sein sollen, kann zwischen dem Spannblech 13 und den von ihnen überspannten Fußflanschen 4 eine Platte 14 aus elektrisch isolierendem Material angeordnet werden. Diese Platte ist vorzugsweise aus Kunststoff ausgebildet und dient auch dazu, Verschleiß zwischen Spannblech 13 und Fußflansch 4 zu verhindern, der durch Vibrationen und Kleinstbewegungen auftreten kann. Je nach Gleislage und Gleisbeanspruchung ist die erfindungsgemäße Befestigung nicht bei jeder Schwelle erforderlich. Es kann jedoch auch sein, daß mehrere Befestigungen an einer Schwelle erforderlich sind. Ebenso kann es sinnvoll sein, diese Befestigung nicht an der Stelle anzuordnen, wie in Fig. 1 dargestellt. In Fig. 1 sind weitere bevorzugte Positionen 15 für die Anbringung einer erfindungsgemäßen Befestigung markiert.According to the invention it is provided that, in contrast to the previously known Fastenings no positive connection between the threshold contact surface and the base 5 is provided. Rather, the foot flange 4 is the Profiles 2 of the Y-shaped steel sleeper lay flat on the base 5. The fixation with the underground takes place via a firmly connected to the underground 5 Anchor 6. In the exemplary embodiment shown there is a bore 7 in the underground brought in. The anchor 6 is then via a dowel 8 with the base 5 connected. The upper end 9 of the armature 6 protruding from the underground has a thread 10, which in cooperation with a nut for bracing 11 the threshold with the underground 5 is used. One designed with a bore 12 Clamping plate 13, which overlaps the respective foot flange 4 of the profiles 2, transfers the tension force of the armature 6 to the steel sleeper. The clamping plate 13 can be resiliently pretensioned on the base 5. Thereby is achieved that it is flat on the outwardly tapering foot flange 4 hangs up. 2, the tensioning plate 13 is in a position that is not or only slightly tensioned shown. Provided that the Y-shaped steel sleepers are insulated from the ground should be formed, can be between the clamping plate 13 and those of them spanned foot flanges 4 a plate 14 made of electrically insulating material to be ordered. This plate is preferably made of plastic and also serves to prevent wear between the clamping plate 13 and the base flange 4, which can occur due to vibrations and small movements. Depending on Track position and track stress is not the attachment according to the invention every threshold required. However, it may also be that several fastenings on a threshold are required. It can also make sense to fix this not to be arranged in place, as shown in Fig. 1. In Fig. 1 are more preferred positions 15 for the attachment of a fastening according to the invention marked.

Die Herstellung der Verbindung des Gleisrostes mit Y-förmigen Stahlschwellen und dem Untergrund 5 kann auf unterschiedliche Weise erfolgen. In den Patentansprüchen 19 und 20 sind diesbezüglich die nacheinanderfolgenden Arbeitsschritte

  • Auflegen des fertigen Gleisrostes auf die feste Fahrbahn
  • Ausrichten des Gleisrostes
  • Herstellen der Ankerlöcher
  • Befestigung der Anker (6) in der festen Fahrbahn
  • soweit erforderlich - Untergießen des Gleisrostes und
  • Verspannen der Schwellen gegen den Untergrund (5) oder
  • Herstellen der Ankerlöcher
  • Befestigen der Anker (6) in der festen Fahrbahn
  • Auflegen des fertigen Gleisrostes auf die feste Fahrbahn
  • Ausrichten des Gleisrostes
  • soweit erforderlich - Untergießen des Gleisrostes und
  • Verspannen der Schwellen gegen den Untergrund (5)
genannt. Andere Arbeitsfolgen sind denkbar. Die entstehende Schicht durch das Untergießen des Gleisrostes, die zwischen dem Fußflansch 4 der Profile 2 und dem Untergrund 5 einzubringen wäre, ist im Ausführungsbeispiel nicht dargestellt.The connection of the track grate with Y-shaped steel sleepers and the base 5 can be done in different ways. In this regard, claims 19 and 20 contain the successive work steps
  • Place the finished track grate on the solid carriageway
  • Aligning the track grate
  • Making the anchor holes
  • Fastening the anchors (6) in the solid road
  • if necessary - pouring under the track grate and
  • Bracing the sleepers against the ground (5) or
  • Making the anchor holes
  • Attach the anchors (6) in the solid roadway
  • Place the finished track grate on the solid carriageway
  • Aligning the track grate
  • if necessary - pouring under the track grate and
  • Tensioning the sleepers against the ground (5)
called. Other work sequences are conceivable. The resulting layer by pouring under the track grate, which would have to be introduced between the base flange 4 of the profiles 2 and the base 5, is not shown in the exemplary embodiment.

Der wesentliche Vorteil der erfindungsgemäßen Befestigung zwischen Gleisrost und Untergrund 5 besteht in der einfachen Ausrichtbarkeit auch noch nach längerer Liegezeit. Hierzu muß lediglich die Mutter 11 gelöst werden. Danach ist das Ausrichten möglich. Sabotagevorrichtungen hinsichtlich dieses Lösens der Mutter 11 auf dem Gewinde 10 des Ankers 6 sind mittels Maßnahmen fachmännischer Art vorzusehen und werden nicht näher beschrieben.The main advantage of the attachment according to the invention between the track grate and surface 5 is easy to align even after a long time Lay time. To do this, only the nut 11 has to be loosened. After that it is Alignment possible. Sabotaging devices regarding this loosening of the mother 11 on the thread 10 of the armature 6 are by means of measures of a professional nature provide and are not described in detail.

Bei festen Fahrbahnen mit einer Asphaltoberschicht kann der Anker 6 so lang ausgebildet sein, daß er sich durch die Asphaltschicht bis in den darunter liegenden Beton erstreckt und hier befestigt ist. Bei Auftreten von Schienenseitenkräften kann es sich durch die Dauerplastizität des Asphalts ergeben, daß der Anker somit eine große Biegelänge erhält, so daß die Schienenlage nicht mehr sicher gewährleistet wird. Nach der Erfindung sind für diesen Fall Maßnahmen vorgesehen, die ein Abstützen des Ankers 6 an der Oberfläche 16 des Untergrundes 5 ermöglichen.In the case of solid road surfaces with an asphalt top layer, the anchor 6 can be made as long be that it runs through the asphalt layer into the one below Concrete stretches and is fastened here. If rail side forces occur it results from the permanent plasticity of the asphalt that the anchor is a receives large bending lengths, so that the rail position is no longer guaranteed becomes. According to the invention, measures are provided for this case which are supported allow the anchor 6 on the surface 16 of the substrate 5.

Bei der Ausbildung nach Fig. 3 sind an der Unterseite des Spannblechs 13 Zylinderstifte 17 angebracht, die bei der Montage und beim Verspannen des Spannblechs 13 in die Oberfläche 16 des in diesem Fall aus einer Asphaltmischung bestehenden Untergrundes 5 eindringen. Durch diese Maßnahme wird eine zusätzliche Lagefixierung des Gleisrostes erreicht.3 are 13 cylindrical pins on the underside of the clamping plate 17 attached, during assembly and when tensioning the clamping plate 13 into the surface 16 of the asphalt mixture in this case Penetrate underground 5. This measure creates an additional Fixed position of the track grate.

Fig. 4 zeigt eine Alternative zum Einsatz der erfindungsgemäßen Befestigung auf Asphaltoberbau. Bei dieser Ausbildung ist in die Oberfläche 16 des aus einer Asphaltmischung bestehenden Untergrundes 5 eine Auflageplatte 18 eingebracht, die sich bis unter die Fußflansche 4 der Profile 2 erstreckt. Diese Auflageplatte 18 kann je nach den Erfordernissen der Fertigung vor oder nach der Herstellung der Asphaltschicht mit dem Anker 6 durch Schweißen verbunden werden. Jedoch auch ohne Schweißverbindung bringt der Einsatz einer Auflageplatte 18 eine Entlastung des Ankers 6.Fig. 4 shows an alternative to using the fastening according to the invention Asphalt superstructure. In this embodiment, the surface 16 is made of an asphalt mixture existing base 5 introduced a platen 18, the extends below the base flanges 4 of the profiles 2. This platen 18th can, depending on the requirements of manufacture before or after the manufacture of the Asphalt layer can be connected to the anchor 6 by welding. But also without a welded connection, the use of a support plate 18 provides relief anchor 6.

Im Ausführungsbeispiel nach den Figuren 5 bis 7 ist etwa mittig in der Schwelle ein Spannblech 13 angeordnet, das mit den Fußflanschen 4 der Stahlschwellen verschweißt ist. Dieses Spannblech 13 weist zentral eine größere kreisförmige Öffnung 19 auf. Der Anker 6 besteht aus einem Grundteil 20, einem Bund 21 und Ankerelementen 22. Das Grundteil 20 liegt in der Öffnung 19 des Spannblechs 13 und wird nach oben von dem Bund 21 abgeschlossen, der auf der Oberfläche des Spannblechs 13 aufliegt. Die Ankerelemente 22 ragen in eine Ausnehmung 23 des Untergrundes 5. Sie sind an ihrem freien Ende mit einem Kopf 24 ausgebildet.In the exemplary embodiment according to FIGS. 5 to 7, the threshold is approximately in the middle Clamping plate 13 arranged, which is welded to the foot flanges 4 of the steel sleepers is. This clamping plate 13 has a larger circular opening centrally 19 on. The armature 6 consists of a base part 20, a collar 21 and Anchor elements 22. The base part 20 lies in the opening 19 of the clamping plate 13 and is completed at the top by the collar 21, which is on the surface of the Clamping plate 13 rests. The anchor elements 22 protrude into a recess 23 of the 5. They are formed with a head 24 at their free end.

Nach dem Ausrichten des Gleisrostes auf dem Untergrund 5 und einem eventuellen, auch teilweisen Untergießen der Schwellen ist die Oberfläche des Untergrundes 5 noch nicht bearbeitet. Erst nach dem Ausrichten hinsichtlich Lage und Höhe wird ein Bohrgerät auf das Spannblech 13 aufgesetzt. Der Bohrer entspricht der Öffnung 19, wird in dieser Öffnung 19 geführt und bohrt eine im Ausführungsfall lochförmige Ausnehmung 23 in den Untergrund 5. Danach wird der Anker 6 mit seinen Ankerelementen 22 durch die Öffnung 19 des Spannblechs 13 in die Ausnehmung 23 des Untergrundes 5 gesetzt und durch Einbringen einer Vergußmasse 25 in die Ausnehmung 23 mit dem Untergrund verbunden.After aligning the track grate on the surface 5 and a possible Partially pouring under the sleepers is the surface of the subsurface 5 not yet processed. Only after aligning in terms of location and height a drill is placed on the clamping plate 13. The drill corresponds to the Opening 19 is guided in this opening 19 and drills one in the case of execution hole-shaped recess 23 in the underground 5. Then the anchor 6 with its anchor elements 22 through the opening 19 of the clamping plate 13 into the recess 23 of the substrate 5 set and by introducing a potting compound 25 connected in the recess 23 to the underground.

In besonderen Fällen kann davor oder danach noch eine Verschraubung des Ankers 6 mit dem Spannblech 13 erfolgen. Wie auch in Fig. 3 gezeigt wird, sind dazu auf dem Spannblech 13 Bolzen 26 aufgeschweißt, die durch Bohrungen des Bundes 21 ragen. Muttern 27 dienen dann zur Verbindung.In special cases, a screw connection of the Anchor 6 take place with the tension plate 13. As also shown in Fig. 3, are for this purpose welded on the clamping plate 13 bolts 26 which through the holes of Federal 21 protrude. Nuts 27 then serve for connection.

Der Anker 6 kann mit einer Eingießöffnung 28 versehen sein, durch die die Vergußmasse 25 eingebracht wird. Nach Einbringen und/oder Aushärten der Vergußmasse kann die Eingießöffnung 28 dann verschlossen werden. Es ist jedoch auch möglich, die Vergußmasse 25 so hoch einzubringen, daß sie auch die Eingießöffnung ausfüllt.The armature 6 can be provided with a pouring opening 28 through which the casting compound 25 is introduced. After the casting compound has been introduced and / or hardened the pouring opening 28 can then be closed. However, it is also possible to bring the potting compound 25 so high that it also the pouring opening fills out.

Im Ausführungsbeispiel ist das Spannblech 13 so mit den Profilen 2 der Schwellen verbunden, daß seine Unterkante bündig zur Unterkante der Schwellen liegt. Es ist jedoch auch möglich, daß das Spannblech 13 die Fußflansche 4 der Profile 2 übergreift und entsprechend höher liegt. Auch andere Formen der Öffnung 19 und der Ausnehmung 23 sind denkbar. In the exemplary embodiment, the clamping plate 13 is so with the profiles 2 of the thresholds connected that its lower edge is flush with the lower edge of the sleepers. It is however, it is also possible for the clamping plate 13 to overlap the foot flanges 4 of the profiles 2 and is correspondingly higher. Other forms of opening 19 and Recess 23 are conceivable.

Für eine eventuelle Demontage des Ankers 6 aus der Ausnehmung 23 des Untergrundes 5 gibt es die Möglichkeit, die Vergußmasse durch Wärme zum Schmelzen zu bringen oder mechanisch, z.B. durch Ausbohren, zu entfernen. For a possible disassembly of the armature 6 from the recess 23 of the base 5 there is the possibility of melting the casting compound by heat to bring or mechanically, e.g. by drilling out.
