Description
Die Erfindung hat einen schotterlosen Oberbau für den schienengebundenen Verkehr mit mit Beton aufgebauten und vorgefertigten Tragplatten zum Gegenstand, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a ballastless superstructure for rail-bound traffic with constructed and prefabricated concrete slabs to the subject, according to the preamble of
Es sind verschiedene Ausführungsformen eines schotterlosen Oberbaues bekannt. Bei einer Konstruktion werden Schwellen mit daran befestigten Schienen in Beton auf der Strecke eingebettet. Eine derartige Konstruktion weist den Nachteil auf, dass eine außerordentlich hohe Justierarbeit erforderlich ist, um eine ebene und geradlinige Ausrichtung der Schienen zu erreichen. Weiters wird dem Umstand nicht ausreichend Rechnung getragen, dass ein Oberbau bei Belastung ausreichend, z. B. um 2 mm bis 3 mm, einfedern und am Ende der Belastung wieder in die Ausgangsstellung gelangen soll.There are various embodiments of a ballastless superstructure known. In one construction, sleepers with rails attached are embedded in concrete on the track. Such a construction has the disadvantage that an extremely high Justierarbeit is required to achieve a flat and rectilinear alignment of the rails. Furthermore, the circumstance is not sufficiently taken into account that a superstructure under load sufficient, z. B. by 2 mm to 3 mm, and at the end of the load should return to the starting position.
Um einen Gleisoberbau wartungsärmer zu machen, ist es bekannt, einen Untergrund zu egalisieren, auf demselben gegebenenfalls eine Betonplatte vorzusehen und auf oder in dieser Befestigungsmittel für die Schienen anzuordnen. Ein derartiger schotterloser Oberbau ist beispielsweise in der
Die Betonplatte wird in ihrer vertikalen Lage durch die Zwischenschichte und das Eigengewicht der Platte gehalten. Die Lage der Platte in der Horizontalen ist durch den erhärteten Beton in den rechteckigen Ausnehmungen bedingt. Damit die Tragplatte das erforderliche Einfedern durchführen kann, weist dieselbe an ihrer Unterseite eine gummielastische Schichte mit einem Trennmittel, z. B. Wachs, auf, über welche dieselbe auf der Zwischenschichte aus Beton aufruht.The concrete slab is held in its vertical position by the intermediate layer and the dead weight of the slab. The position of the plate in the horizontal is due to the hardened concrete in the rectangular recesses. Thus, the support plate can perform the required compression, it has on its underside a rubber-elastic layer with a release agent, eg. Wax, over which it rests on the intermediate layer of concrete.

Der Erfindung ist zur Aufgabe gestellt, einen schotterlosen Oberbau mit Tragplatten zu schaffen, wobei eine sichere Auflagerung der Tragplatten auf dem Untergrund erfolgen kann und eine entsprechende Einfederung auch gegeben ist, wobei eine vollflächige Einbringung des Vergussmörtels leicht möglich ist, und auch der Ersatz einer Tragplatte ohne schweres Hebezeug möglich ist, da keine mechanischen Verbindungen zwischen der gummielastischen Schichte und dem Vergussmörtel vorliegen.The invention has for its object to provide a ballastless superstructure with support plates, with a safe Auflagerung the support plates can be done on the ground and a corresponding deflection is also given, a full-surface introduction of the grout is easily possible, and also the replacement of a support plate Without heavy lifting equipment is possible because there are no mechanical connections between the rubber-elastic layer and the grouting mortar.
Der erfindungsgemäße schotterlose Oberbau für den schienengebundenen Verkehr mit mit Beton aufgebauten vorgefertigten Tragplatten, die zumindest zwei Schienen tragen, in Schienenlängsrichtung eine größere Erstreckung als normal hierzu aufweisen, und zumindest zwei rechteckige durchgehende zum Untergrund offene Ausnehmungen aufweisen, und über eine gummielastische Schichte, die mit Gummigranulat, das mit einem gummielastischen Bindemittel gebunden ist, über eine Vergussmasse mit hydraulischem und latenthydraulischem Bindemittel mit auf einem Untergrund über ein Trennmittel aufruhen, besteht im Wesentlichen darin, dass die gummielastische Schichte an zumindest einer Fläche, die von der Vergussmasse beaufschlagt ist,) mit einem pastösen Trennmittel glatt egalisiert ist, und die Ausnehmungen nach oben verjüngend ausgebildet sind.The ballastless superstructure according to the invention for rail-bound transport constructed with concrete prefabricated support plates which carry at least two rails, in the rail longitudinal direction have a greater extent than normal thereto, and at least two rectangular continuous open to the ground recesses, and a rubber-elastic layer with Rubber granulate, which is bound with a rubber-elastic binder, resting on a potting compound with hydraulic and latent hydraulic binder with a substrate on a release agent, essentially consists in that the rubber-elastic layer on at least one surface, which is acted upon by the potting compound , with) a pasty release agent is leveled smooth, and the recesses are tapered upwards.
Sind die zur Vergussmasse weisenden Flächen, also jene Flächen, die von der Vergussmasse beaufschlagt werden, im Wesentlichen durch die pastösen Trennmittel glatt und somit ohne Vertiefungen ausgebildet, so kann die Vergussmasse nicht mehr in die gummielastische Schichte eindringen und einen Formschluss bedingen. Gleichzeitig wird durch diese Oberflächenausbildung der gummielastischen Schichte ein Strömungskanal für die Vergussmasse gebildet, der glatte Wände aufweisen kann. Somit kann die Vergussmasse besonders leicht den Zwischenraum zwischen gummielastischer Schichte und dem Untergrund erfüllen. Sind die Ausnehmungen nach oben verjüngend ausgebildet, so ist einerseits eine exakte Positionierung der Tragplatten am Untergrund möglich, und andererseits kann damit auch in den Ausnehmungen selbst ein Formschluss zwischen der Tragplatte und dem Vergussmörtel vermieden werden.If the surfaces facing the potting compound, ie those surfaces which are acted on by the potting compound, are substantially smooth and thus without depressions, then the potting compound can no longer penetrate into the rubber-elastic layer and cause a positive connection. At the same time a flow channel for the potting compound is formed by this surface formation of the rubber-elastic layer, which may have smooth walls. Thus, the potting compound is particularly easy to meet the gap between rubber-elastic layer and the substrate. If the recesses are tapered upwards, an exact positioning of the support plates on the substrate is possible on the one hand, and on the other hand a positive connection between the support plate and the grout can thus be avoided even in the recesses themselves.
Weist das Trennmittel 20,0 Gew.-% bis 45,0 Gew.-%, insbesondere 25,0 Gew.-% bis 40,0 Gew.-%, Füllstoff auf, so kann die erwünschte Viskosität des Trennmittels besonders einfach eingestellt werden, da es lediglich erforderlich ist, einen höheren Anteil an Füllstoff vorzusehen, um die Viskosität zu steigern.If the release agent has 20.0% by weight to 45.0% by weight, in particular 25.0% by weight to 40.0% by weight, of filler, the desired viscosity of the release agent can be set particularly easily since it is only necessary to provide a higher proportion of filler in order to increase the viscosity.
Weist die gummielastische Schichte zumindest zwei miteinander über ein gummielastisches Bindemittel verbundene Schichten auf, so ist durch die mehrschichtige Ausbildung eine Anpassung an bestimmte gummielastische Eigenschaften besonders einfach zu erreichen, so können die unterschiedlichen Schichten unterschiedliche gummielastische Eigenschaften aufweisen. Diese können durch unterschiedliche Gummiteilchen, unterschiedliche Größe oder unterschiedliche Bindemittel erreicht werden.If the rubber-elastic layer has at least two layers connected to one another via a rubber-elastic binder, it is particularly easy to achieve adaptation to specific rubber-elastic properties by the multi-layered design, then the different layers can have different rubber-elastic properties. These can be achieved by different rubber particles, different size or different binders.
Ist die gummielastische Schichte mit der Tragplatte über ein gummielastisches Bindemittel verbunden, so kann auch bei höheren Beanspruchungen eine Zerstörung der gummielastischen Schichte vermieden werden, da die Kräfte teilweise elastisch aufgenommen werden können.If the rubber-elastic layer connected to the support plate via a rubber-elastic binder, so destruction of the rubber-elastic layer can be avoided even at higher loads, since the forces can be partially absorbed elastically.
Weisen die Teilchen des Gummigranulates eine maximale Erstreckung von 1 mm bis 4 mm, insbesondere 2 mm bis 3 mm, auf, so ist eine besonders feinkörnige Struktur gegeben, die einfach und wirkungsvoll mit einem pastösen Trennmittel egalisiert werden können.If the particles of the rubber granules have a maximum extent of 1 mm to 4 mm, in particular 2 mm to 3 mm, a particularly fine-grained structure is provided, which can be leveled easily and effectively with a pasty release agent.
Weisen die Teilchen des Gummigranulates eine Shorehärte von 50 bis 80 auf, so kann eine lange Lebensdauer bei dynamischer Belastung erreicht werden.If the particles of the rubber granules have a Shore hardness of 50 to 80, a long service life under dynamic load can be achieved.
Weisen die Teilchen des Gummigranulates eine Verstärkung aus Fasern, insbesondere Kunststofffasern, auf, so kann damit das Einfederungsverhalten gesteuert werden.If the particles of the rubber granules have a reinforcement of fibers, in particular plastic fibers, then the deflection behavior can be controlled.

Beispiele für pastöse Trennmittel sind mit Paraffin, höher viskose Öle, auch wässrige Emulsionen dieser Trennmittel mit einem Füllstoff, z. B. Zinkoxid, Kreide, Kalkmehl.Examples of pasty release agents are paraffin, higher viscosity oils, and aqueous emulsions of these release agents with a filler, eg. As zinc oxide, chalk, lime.
Zum Austausch einer Tragplatte, deren gummielastische Schichte lediglich mit einem Trennmittel versehen ist, das keine Egalisierung bewirkt, ist zum Abheben eine Hebekraft von 96 t pro Platte erforderlich. Wird eine Tragplatte gleicher Größe abgehoben, deren gummielastische Schichte mit einem pastösen Trennmittel egalisiert ist, so wird nur ca. ein Zwanzigstel der Hebekraft, u. zw. 4,2 t, erforderlich.To replace a support plate whose rubber-elastic layer is provided only with a release agent that causes no leveling, a lifting force of 96 t per plate is required to take off. If a support plate of the same size lifted, the rubber-elastic layer is leveled with a pasty release agent, so only about one twentieth of the lifting force, u. between 4.2 t, required.
