Bei dem bekannten schotterlosen Oberbausystem, von dem die Erfindung ausgeht (DE 23 54 958 B2), sind auf der Tragschicht unter Zwischenschaltung einer Ausgleichsschicht bis zu 6 m lange vorgefertigte Betonfahrbahnplatten angeordnet, die in Längsrichtung gereiht angeordnete Aufnahmeeinrichtungen für die einzelnen Eisenbahnschienen und deren Schienenbefestigungsvorrichtungen aufweisen. Die Aufnahmeeinrichtungen bestehen aus an die vorgefertigten Betonfahrbahnplatten angeformten Aufkantungen und gegenüber der Oberfläche der Betonfahrbahnplatten erhöhten Auflageflächen für die Schienenbefestigungsvorrichtungen. Die bekannte Ausführungsform genügt nicht den Tolerenzanforderungen, die insbesondere bei Hochgeschwindigkeitsstrecken gestellt werden müssen, was darauf beruht, daß große vorgefertigte Betonfahrbahnplatten nicht ausreichend tolzenzarm verlegt werden können. Die bekannten Maßnahmen sind außerdem in herstellungstechnischer und montagetechnischer Hinsicht aufwendig. Ohne weiteres sind die beschriebenen Bauteile unter Berücksichtigung der hohen Beanspruchungen nicht hinreichend schub- und druckfest miteinander verbunden, was störende Toleranzveränderungen auslösen kann. Ähnlich liegen die Verhältnisse bei einem schotterlosen Oberbausystem (DE 23 54 960 B2), bei dem die Betonfahrbahnplatte, die in Ortbeton hergestellt oder aus vorgefertigten Elementen zusammengesetzt sein kann, langlaufende Nuten aufweist, in die mit Abstand voneinander U-förmige Aufnahmeeinrichtungen aus Beton eingesetzt sind, welche die Schienenbefestigungsvorrichtungen und die Schienen aufnehmen.In the known ballastless track system, of which the invention is based (DE 23 54 958 B2) are on the Base layer with the interposition of a leveling layer Prefabricated concrete slabs up to 6 m long arranged, arranged in the longitudinal direction Receiving facilities for the individual railroad tracks and their rail fastening devices exhibit. The reception facilities consist of the prefabricated concrete slabs and against the surface of the concrete pavement slabs increased contact surfaces for the rail fastening devices. The known embodiment is sufficient not the tolerance requirements, in particular with High-speed lines have to be put what is based on the fact that large prefabricated concrete road slabs not to be laid with sufficient wadding can. The known measures are also in manufacturing technology and assembly-technically complex. The components described are easily below Consideration of the high demands is insufficient shear and pressure resistant connected what can trigger disturbing tolerance changes. Similar are the conditions for a ballastless track system (DE 23 54 960 B2), in which the concrete slab, those made in in-situ concrete or from prefabricated Elements can be composed of long-running Has grooves in the U-shaped at a distance from each other Receiving devices made of concrete are used, which the rail fasteners and the rails record, tape.

Der Erfindung liegt das technische Problem zugrunde, ein schotterloses Oberbausystem für zumindest ein Eisenbahngleis anzugeben, welches unschwer toleranzarm hergestellt werden kann und insbesondere allen Anforderungen genügt, die bei Hochgeschwindigkeitsstrecken gestellt werden müssen.

Der Aufbau der Tragschicht richtet sich nach dem Untergrund. Die Tragschicht weist die erforderlichen Zuschlagstoffe auf und ist zumeist zementgebunden. Im allgemeinen ist bei dem erfindungsgemäßen schotterlosen Oberbausystem zumindest die obere der beiden Schichten der Betonfahrbahnplatte als faserbewehrte Betonschicht ausgeführt. Auf diese Weise kann unkontrollierte Rißbildung unter den aufzunehmenden statischen, dynamischen thermischen Beanspruchungen in der oberen Schicht der Betonfahrbahnplatte sicher verhindert werden, so daß die eingerichteten Toleranzen nicht durch unkontrollierte Rißbildungen verschlechtert werden.To solve this technical problem is the subject of Invention a ballastless track system for at least a railroad track consisting of two railroad tracks, in particular for high-speed lines - with a base layer, a concrete slab and receiving facilities for the individual railroad tracks, the Railroad tracks using rail fasteners are attached in the receiving devices, which are designed as rail base elements, whereby the rail base elements on their top Have cavities in which the rail fastening devices and rail feet fastened in it individual railroad tracks are arranged, furthermore the rail fastening devices and thus the Rail feet with the help of rail fastening screws in the manner of sleeper screws, which are screwed into the rail base elements, are held in the cavities and the Base layer to accommodate the static and dynamic Stresses is set up, characterized in that that the concrete slab is continuously manufactured and consists of two layers made on top of each other, between them a reinforcement in the direction of the track reinforcement bars running and running across them is arranged, the concrete of the two layers of Concrete roadway slab in the reinforcement mesh is connected, and that the rail base elements concreted into the upper layer of the concrete carriageway slab and with reinforcement components in the form of reinforcement loops or reinforcement cages in both layers of the Concrete slab are anchored.

Daher wird im Rahmen der Erfindung auch von Betonfahrbahnplatten gesprochen. Einfach ist auch das Einbetonieren der Schienenstützpunktelemente, weil entsprechende Aggregate in einen üblichen Straßenfertiger leicht eingebaut werden können. Da die Schienenstützpunktelemente einbetoniert sind, nehmen sie Schubbeanspruchungen in Gleisrichtung und quer dazu ohne weiteres auf, ohne daß eine Toleranzbeeinträchtigung und entsprechende Versetzungen oder Verschiebungen in Kauf genommen werden müssen.The ballastless superstructure system according to the invention is in In-situ concrete erected.

Betrachtet man die Fig. 4, so erkennt man, wie verfahren wird, wenn nicht Bewehrungsschlaufen 10, sondern Bewehrungskörbe 11 eingesetzt werden. Hier ist in die Betonfahrbahnplatte 3 zunächst eine Bohrung 22 mit Hinterschneidung 23 eingebracht, in die an der Schalung 20 für die Schienenstützpunktelemente 4 befestigte Bewehrungskörbe 11 eingeführt werden. Hier ist die Betonierung noch nicht erfolgt. Man erkennt, daß sie unschwer durchgeführt werden kann. Zwischen den beiden Bewehrungskörben 11 ist ein Bereich 24 der Betonfahrbahnplatte 3 stehengeblieben, und zwar um eine sichere Verankerung des Betons für die Schienenstützpunktelemente 4 in diesem Bereich zu bewirken.If you look at Fig. 3, you can see a formwork 20, which is set up and destined to manufacture of a track system according to the invention the rail base elements 4 to be made from in-situ concrete. It understands itself that the in-situ concrete in the formwork interior is introduced. In the exemplary embodiment it is already filled. He was hatched accordingly identified. It can be seen that reinforcement components in Form of reinforcement loops 10 in both layers 6, 7 of the concrete slab 3 are anchored in the Protrude inside the mold. The formwork 20 supports Spring clips 21 dowels 15 for the threshold screws 14. Es is understood that after concreting the rail base elements 4 in the course of manufacturing the top Layer 7 of the concrete carriageway slab 3 the formwork elements be implemented. If one looks at FIG. 4, one sees how to proceed, if not reinforcement loops 10, but reinforcement cages 11 are used. Here there is initially a bore 22 in the concrete carriageway slab 3 introduced with undercut 23, in which at the Formwork 20 for the rail base elements 4 fixed reinforcement cages 11 are introduced. Here is the concreting has not yet taken place. You can see that she can be carried out easily. Between the two Reinforcement cages 11 is an area 24 of the concrete carriageway slab 3 stopped, namely a safe one Anchoring the concrete for the rail base elements 4 in this area.

Die Fig. 6 verdeutlicht, daß ein erfindungsgemäßes schotterloses Oberbausystem auf einfache Weise kontinuierlich gefertigt werden kann. Die Figur zeigt das Schema einer entsprechenden Einrichtung. Die Arbeitsrichtung wurde durch Pfeile angedeutet. Man erkennt an der linken Seite der Fig. 6 am vorderen Ende des Fertigers 25 einen Aufnahmetrichter 26 für den Beton, der über geeignete Einrichtungen bei marschierendem Fertiger 25 als Unterschicht 6 bzw. Oberschicht 7 der Betonfahrbahnplatte 3 eingebracht wird, untere Schicht 6 und obere Schicht 7 mit räumlichem und zeitlichem Abstand. Man erkennt fernerhin die höhenverstellbaren Fahrwerke 27, die eingerichtet sind, um die Dicke der Betonfahrbahnplatte 3 einzustellen und auch die Dicke der einzelnen Schichten 6, 7. Der Fertiger 25 ist mit einem Fahrerstand 28 ausgerüstet, er besitzt einen Grundrahmen 29, der durch Traversen verbunden ist. Eingebaut in dieses System sind der Dübelbesetzer 30, eine Einrichtung 31 für das Einbringen der Längsbewehrung 32 mit Vorratsrolle 33 und eine Einrichtung 34 für das Einbringen der Querbewehrung 35 mit Vorratskammer 36. Der Einbau des Betons der oberen Schicht 7 erfolgt mit nachgeschaltetem Fahrbahnglätter 37. Man erkennt außerdem eine Einrichtung 38 zum Eindrücken der Schlaufenbewehrungen 10, mit denen die Schienenstützpunktelemente 4 mit den beiden Schichten 6, 7 der Betonfahrbahnplatte 3 verankert werden. Sollen nicht Schlaufenbewehrungen 10, sondern Bewehrungskörbe 11 eingesetzt werden, wie sie in Fig. 4 dargestellt wurden, so wird anstelle der Einrichtung 38 eine Einrichtung angeschlossen, die in die Betonfahrbahnplatte 3 zunächst die hinterschnittenen Bohrungen 22 einbringt und freispült oder freibläst, in die danach die Bewehrungskörbe 11 eingesetzt werden, wenn die schon beschriebenen Schalungen 20 für die Schienenstützpunktelemente 4 positioniert werden.Fig. 6 illustrates that a ballastless according to the invention Track system in a simple, continuous manner can be manufactured. The figure shows the scheme of a appropriate facility. The direction of work was indicated by arrows. You can see it on the left side 6 at the front end of the paver 25 Receiving funnel 26 for the concrete, which has suitable Facilities with marching paver 25 as a lower layer 6 or top layer 7 of the concrete carriageway slab 3 is introduced, lower layer 6 and upper layer 7 with a spatial and temporal distance. One notices furthermore the height-adjustable undercarriages 27, which are set up the thickness of the concrete slab 3 adjust and also the thickness of each layer 6, 7. The paver 25 is with a driver's cab 28 equipped, he has a base frame 29 through Trusses connected. Are built into this system the dowel occupant 30, a device 31 for the insertion the longitudinal reinforcement 32 with supply roll 33 and a device 34 for the introduction of the transverse reinforcement 35 with pantry 36. Installation of the concrete of the upper Layer 7 is carried out with a road smoothing device downstream 37. A device 38 for impressing can also be seen the loop reinforcements 10 with which the Rail base elements 4 with the two layers 6, 7 of the concrete slab 3 are anchored. Should not loop reinforcements 10, but reinforcement cages 11 are used, as shown in Fig. 4, so instead of the device 38 becomes a device connected to the concrete slab 3 initially introduces the undercut bores 22 and flushes them out or blows them into the reinforcement cages 11 are used if the already described Formwork 20 for the rail base elements 4 be positioned.
