Description

Die Erfindung betrifft eine Feste Fahrbahn für schienengebundene Fahrzeuge auf einer Brücke, gemäß dem Oberbegriff der Ansprüche 1 und 7, wobei die Feste Fahrbahn sich aus einer Brückenüberbauplatte, einer diese abdeckenden Tragplatte sowie einer Oberbauplatte zusammensetzt, auf der Schienen mit Befestigungsmitteln angeordnet sind.The invention relates to a slab track for rail vehicles on a bridge, according to the preamble of claims 1 and 7, wherein the slab is composed of a bridging plate, a covering this supporting plate and a top plate, are arranged on the rails with fastening means.

Auf den Schnellverkehrsstrecken der Eisenbahn haben sich in den letzten Jahren immer mehr sogenannte Feste Fahrbahnen durchgesetzt. Bei diesen Konstruktionen sind die Schienen nicht auf in einem Schotterbett angeordneten Schwellen befestigt, sondern auf einer Stahlbetontragplatte aufgelagert. Die Verwendung der Festen Fahrbahn für Hochgeschwindigkeitsstrecken liegt in der besseren Lagekonstanz und der infolge längerer Instandhaltungsintervalle größeren Verfügbarkeit begründet.On the high-speed railway lines, more and more so-called slab tracks have gained acceptance in recent years. In these constructions, the rails are not mounted on sleepers arranged in a ballast bed but are supported on a reinforced concrete slab. The use of the slab track for high-speed lines is due to the better positional stability and the greater availability due to longer maintenance intervals.

Das Auflegen einer Festen Fahrbahn auf Brücken stellt bislang ein Problem dar. Bei einer Festen Fahrbahn mit durchgehend verschweißten Schienen verbleibt jeder Querschnitt praktisch bei jeder Temperatur nahezu unverschiebbar ortsgebunden, wobei Temperaturänderungen lediglich Spannungsänderungen in den Schienen verursachen. Da es bei Brückenkonstruktionen infolge Temperaturänderungen zu Längenänderungen kommt, stellt die Kombination einer Festen Fahrbahn mit einer Brücke ein schwierig zu lösendes Problem dar.Laying a slab track on bridges has been a problem so far. In a slab track with continuously welded rails, each cross section remains virtually stationary at virtually any temperature, with temperature changes merely causing voltage changes in the rails. Since length changes occur in bridge constructions due to temperature changes, the combination of a slab track with a bridge is a difficult problem to solve.

Zur Lösung des Problems wurde in der DE 24 43 770 vorgeschlagen, die Tragplatte auf der Brückenkonstruktion längsverschiebbar anzuordnen, so dass die Brückenkonstruktion sich unter der Festen Fahrbahn bewegen kann. Die Aufnahme und Weiterleitung der potentiell sehr großen Kräfte beim Bremsen eines Zuges erfolgt in die Tragplatte, die sie an den Brückenüberbau abgeben muss. Die Verteilung der Bremskräfte auf die Brücke und die durchlaufenden Schienen ist sehr problematisch zu bemessen.To solve the problem was in the DE 24 43 770 proposed to arrange the support plate on the bridge structure longitudinally displaceable, so that the bridge construction can move under the slab track. The recording and transmission of the potentially very large forces when braking a train takes place in the support plate, which must deliver it to the bridge superstructure. The distribution of braking forces on the bridge and the continuous rails is very problematic to measure.

Um dieses Problem zu vermeiden sind feste Fahrbahnen für schienengebundene Fahrzeuge auf Brücken entwickelt worden, die als System "Rheda" bekannt sind. Bei diesem System wird zum Schutz der Oberflächendichtung auf der Brückenüberbauplatte eine Tragplatte aufgebracht, die im Bereich der Gleise Verstärkungsstreifen größerer Dicke aufweist, in denen im Längsabstand voneinander Vertiefungen angeordnet sind. Auf diesen Verstärkungsstreifen liegen Oberbauplatten, die mit Spornen an ihrer Unterseite in die Vertiefungen in den Verstärkungsstreifen der Tragplatte eingreifen und so mit dieser formschlüssig verbunden sind.
Die Herstellung dieser bekannten Festen Fahrbahn ist zeitaufwendig und kostspielig und erfordert erhebliche Materialaufwendungen, so dass das Gewicht und die Bauhöhe bei einseitiger Gleisüberhöhung zu groß werden.To avoid this problem, fixed tracks for rail vehicles have been developed on bridges known as the "Rheda" system. In this system, a support plate is applied to protect the surface seal on the bridge superstructure plate, which has reinforcing strips of greater thickness in the region of the tracks, in which recesses are arranged at a longitudinal distance from each other. Lie on these reinforcing strips Oberbauplatten which engage with spurs on their underside in the recesses in the reinforcing strip of the support plate and are thus positively connected.
The preparation of this known slab track is time consuming and costly and requires considerable material costs, so that the weight and height are too large in one-sided track cant.

Bekannt ist die DE 196 20 731 A1 , die sämtliche Merkmale des Oberbegriffs des Ansrpuchs 1 offenbart, wobei eine feste Fahrbahn für schienengebundene Fahrzeuge auf Brücken beschrieben wird, die sich aus einer Brückenüberbauplatte, einer Tragplatte und einer Oberbauplatte zusammensetzt. Die Oberbauplatte weist dabei Ausnehmungen für einzelne Höcker auf, die jeweils an den Längsenden der Tragplatte angeordnet sind. Die Ausnehmungen der Oberbauplatte umgreifen bei dieser Konstruktion die Höcker der Tragplatte.
Diese Konstruktion erfordert eine aufwändige Längsbewehrung und ein sehr genaues Arbeiten. Dadurch ist ein großer Arbeits- und Zeitaufwand notwendig. Außerdem werden die Verstärkungsstreifen der Tragplatten sowie die Oberbauplatte jeweils nur mit geringer Länge von maximal 6 m ausgeführt. Das erfordert eine Vielzahl von Platten auf einer Brücke und aufwendige Schalungs- sowie Bewehrungsarbeiten für die Betonplatte und die Stopper. Durch die Anordnung der Stopper jeweils an den Enden der Platten der Konstruktion muss jede Platte zwei Stopper aufweisen.The is known DE 196 20 731 A1 US-A-4 837 847 which discloses all the features of the preamble of claim 1, wherein a fixed track for rail vehicles is described on bridges composed of a bridge overpass plate, a support plate and a superstructure plate. The top plate has recesses for individual bumps, which are each arranged at the longitudinal ends of the support plate. The recesses of the superstructure surround the humps of the support plate in this construction.
This construction requires a complex longitudinal reinforcement and a very accurate work. This requires a great deal of work and time. In addition, the reinforcing strips of the support plates and the top plate are each carried out only with a short length of a maximum of 6 m. This requires a variety of plates on a bridge and elaborate formwork and reinforcement work for the concrete slab and the stopper. Due to the arrangement of the stoppers respectively at the ends of the plates of the construction, each plate must have two stoppers.

Desweiteren ist ein Verfahren zur Fertigung einer festen Schienenfahrbahn auf einer Brücke bekannt, die in Längsrichtung der Schienenfahrbahn Vertiefungsbereiche aufweist ( DE 100 04 194 A1 ), und sämtliche Merkmale des Oberbegriffs des Anspruchs 7 offenbart.Furthermore, a method for producing a fixed rail track on a bridge is known, which has recessed areas in the longitudinal direction of the rail track ( DE 100 04 194 A1 ), and all features of the preamble of claim 7 disclosed.

Der Erfindung liegt die Aufgabe zugrunde, eine Konstruktion zu entwickeln, die eine einfachere Längsbewehrung und einen verminderten Schalungs- sowie Fertigungsaufwand erfordert sowie die Herstellung längerer Platten ermöglicht. Dies wird erfingdungsgemäß durch die Merkmale der Ansprüche 1 and 7 erreicht.The invention has for its object to develop a construction that requires a simpler longitudinal reinforcement and a reduced formwork and manufacturing costs and allows the production of longer plates. This is achieved according to the invention by the features of claims 1 and 7.
