Description

Die Erfindung betrifft eine Einrichtung zur elastischen Lagerung einer Rillenschiene mit einem Schienenfuß, einem eine Spurrille aufweisenden Schienenkopf und einem den Schienenfuß und den Schienenkopf verbindenden Schienensteg, wobei die Einrichtung eine unterhalb des Schienenfußes angeordnete elastische Platte, beiderseits des Schienensteges angeordnete Stützteile und auf den vom Schienensteg abgewandten Seiten der Stützteile angeordnete elastische Lagen aufweist.The invention relates to a device for the elastic mounting of a grooved rail with a rail foot, a rail head with a track groove and a rail web connecting the rail foot and the rail head, wherein the device an elastic arranged below the rail foot Plate, arranged on both sides of the rail web supporting parts and on the Elastic layers arranged on the sides of the support parts facing away from the rail web having.

Eine solche Einrichtung wurde z.B. durch die EP 0 308 876 B1 bekannt. Bei dieser bekannten Einrichtung ist ein im Querschnitt U-förmiger Profilkörper vorgesehen, dessen Schenkel an ihren freien Enden mit gegeneinander und damit gegen den Schienenkopf gerichteten Kopfleisten versehen sind. Dieser Profilkörper weist eine äußere Schale auf, die aus einer Bodenplatte, zwei Seitenwangen, welche äußere Stützteile der bekannten Einrichtung bilden, und den bereits erwähnten beiden Kopfleisten besteht, durch die eine insgesamt hinterschnittene U-Form gebildet ist, wobei die Kopfleisten an dem Schienenkopf anliegen. Im verlegten und eingebauten Zustand liegt das umgebende Bodenmaterial, wie z.B. Fahrbahnplatten, an der im wesentlichen glatten Außenseite der äußeren Stützteile an.Such a device was e.g. known from EP 0 308 876 B1. At this known device, a cross-sectionally U-shaped profile body is provided, whose legs at their free ends with each other and thus against the rail head directed headers are provided. This profile body has an outer shell that consists of a base plate, two side cheeks, which form outer support parts of the known device, and those already mentioned there are two headers through which an overall undercut U-shape is formed, the headers abutting the rail head. I'm misplaced and installed condition, the surrounding floor material, e.g. Roadway slabs, on the substantially smooth outside of the outer support members on.

Weiters weist die bekannte Einrichtung eine innere Schale aus zelligem Polyurethan-Elastomer auf, die aus einem Bodenteil, zwei Seitenteilen, die an den Innenseiten der Schenkeln des U-förmigen Profiles der äußeren Schale anliegen, und zwei Kopfteile, die an der Unterseite der Kopfleisten gehalten sind, gebildet ist. Diese Teile der inneren Schale sind mit den korrespondierenden Teilen der äußeren Schale fest verbunden, jedoch nicht mit den übrigen Teilen der inneren Schale.Furthermore, the known device has an inner shell made of cellular polyurethane elastomer on, which consist of a bottom part, two side parts on the inside of the legs of the U-shaped profile of the outer shell, and two head parts, which are held on the underside of the head strips, are formed is. These parts of the inner shell are with the corresponding parts of the outer shell firmly connected, but not to the remaining parts of the inner Bowl.

Die Teile der äußeren Schale des Profilkörpers sind fest miteinander verbunden, wobei jedoch die Seitenwangen elastisch federnd nach außen gebogen werden können, um die Schiene und Füllsteine, die innere Stützteile darstellen und meist aus Beton gefertigt sind und zur Stützung der Seitenwangen der äußeren Schale von innen her dienen, in das Profil einsetzen zu können. Dabei stützen sich die Füllsteine an der Schiene und den Seitenteilen der inneren Schale ab. Nachteilig bei dieser bekannten Lösung ist die relativ aufwendige Herstellung und Montage.The parts of the outer shell of the profile body are firmly connected to one another, however, the side cheeks are resiliently bent outwards can to the rail and filler blocks that represent inner support parts and mostly are made of concrete and to support the side cheeks of the outer shell serve from the inside to be able to insert into the profile. The support themselves Fill stones on the rail and the side parts of the inner shell. A disadvantage of this known solution is the relatively complex manufacture and Assembly.

Auch kommt es, wenn dieser Profilkörper in die Fahrbahn einbetoniert wird, im Laufe der Zeit zu einem Eindringen von Wasser zwischen dem Profilkörper und dem angrenzenden Beton, wobei Frostaufbrüche im Beton die Folge sind.It also happens when this profile body is concreted into the road, in Over time, water penetration between the profile body and the adjacent concrete, resulting in frost bursts in the concrete.

Weiters kommt es beim Überfahren der Gleise durch ein Schienenfahrzeug zu einer gewissen Schwingung bzw. Auslenkung des Schienenkopfes. Eine Schienenlagerung muß so ausgebildet sein, daß sie solche Auslenkungen auf die geringen erlaubten Werte begrenzt. Die bei der aus der EP 0308876 B1 vorbekannten Einrichtung am Schienenkopf anliegenden Kopfleisten müssen daher aus einem relativ starren Material bestehen, um eben diese Auslenkungen des Schienenkopfes ausreichend begrenzen zu können, wodurch aber die Schwingungsdämpfung beeinträchtigt wird und es zu Lärmbelästigungen der Anrainer kommt.Furthermore, it happens when a rail vehicle crosses the tracks a certain vibration or deflection of the rail head. A rail storage must be designed so that they have such deflections to the minor allowed values are limited. Those known from EP 0308876 B1 The head rails that are attached to the rail head must therefore be off a relatively rigid material to just these deflections of the rail head to be able to limit it sufficiently, but this reduces the vibration damping is impaired and noise pollution of the residents occurs.

Eine weitere Einrichtung der eingangs genannten Art ist aus der AT 172 157 B bekannt. Um ein Eindringen von Wasser zwischen den Stützteilen und den elastischen Lagen zu vermeiden sind die elastischen Lagen mit einer Vorspannung zwischen den Stützteilen und dem umgebenden Beton der Straßendecke eingebaut.Another device of the type mentioned is from AT 172 157 B. known. To prevent water from entering between the support parts and the elastic Layers are to be avoided with elastic layers with a pre-tension installed between the supporting parts and the surrounding concrete of the road surface.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine verbesserte Einrichtung der eingangs erwähnten Art bereitzustellen, die sich durch einen einfachen Aufbau auszeichnet und einfach montierbar ist und eine elastische Lagerung der Schiene bei einer definierten Begrenzung der Auslenkung des Schienenkopfes auch in einem Dauereinsatz ermöglicht.The aim of the invention is to avoid these disadvantages and to provide an improved device to provide the type mentioned above, which is characterized by a simple Structure is distinguished and easy to assemble and elastic storage the rail with a defined limitation of the deflection of the rail head also possible in continuous use.

Erfindungsgemäß wird dies bei einer Einrichtung der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.According to the invention, this is achieved with a device of the type mentioned at the beginning achieved by the characterizing features of claim 1.

Durch die vorgeschlagenen Maßnahmen wird erreicht, daß durch die Lagerteile eine sehr gute Abstützung des Schienensteges und damit auch des Schienenkopfes gegeben ist, wobei durch die elastische Lage eine entsprechende Dämpfung bei der Übertragung von Schwingungen gewährleistet ist. Auch lassen sich die Lagerteile sehr leicht montieren. Weiters wird durch das dreidimensionale Gitter eine sehr gute Verbindung zwischen den Lagerteilen und dem die Einrichtung umgebenden Beton erreicht. Ablösungen zwischen den Lagerteilen und dem Beton können dadurch auch nach einer längeren Einsatzzeit verhindert werden, so daß keine Zwischenräume für eindringendes Wasser entstehen und Frostaufbrüche vermieden werden.The proposed measures ensure that the bearing parts very good support for the rail web and thus also the rail head is given, with the corresponding elastic damping is guaranteed in the transmission of vibrations. Also can be mount the bearing parts very easily. Furthermore, the three-dimensional Lattice a very good connection between the bearing parts and the device surrounding concrete reached. Detachments between the bearing parts and the Concrete can thus be prevented even after a long period of use, so that there are no gaps for penetrating water and frost breaks be avoided.

In einem vorteilhaften Ausführungsbeispiel der Erfindung sind die Montagegitter im Material der mit den Stützteilen fest verbundenen elastischen Lagen eingebettet bzw. in dieses einkaschiert. Es wird dadurch eine äußerst stabile und haltbare materialschlüssige Verbindung zwischen dem Montagegitter und der elastischen Lage und ein insgesamt sehr einfacher Aufbau der elastischen Schienenlagerung erreicht.In an advantageous embodiment of the invention, the mounting grids embedded in the material of the elastic layers firmly connected to the support parts or laminated into it. This makes it extremely stable and durable Material connection between the assembly grid and the elastic Location and an overall very simple structure of the elastic rail mounting reached.

Die erfindungsgemäße Einrichtung dient zur elastischen Lagerung einer Schiene 20, die einen Schienenfuß 1 aufweist, der über einen Schienensteg 2 mit einem Schienenkopf 3 verbunden ist. Dieser Schienenkopf 3 weist eine Spurrille 4 auf.The device according to the invention serves for the elastic mounting of a rail 20, which has a rail foot 1, which has a rail web 2 with a Rail head 3 is connected. This rail head 3 has a track groove 4.

An der Unterseite des Schienenfußes 1 ist eine elastische Platte 6 befestigt, die vorzugsweise mit dem Schienenfuß 1 verklebt ist. Die elastische Platte 6 liegt auf einem Untergrund 5 auf, der z.B. durch eine Stahlbetonplatte gebildet ist, wobei zur Festlegung der korrekten Höhenlage des Schienenkopfes 3 Höhenausgleichsplatten zwischen dem Untergrund 5 und der elastischen Platte 6 angebracht werden können. On the underside of the rail foot 1, an elastic plate 6 is attached, the is preferably glued to the rail foot 1. The elastic plate 6 lies on a base 5, e.g. is formed by a reinforced concrete slab, wherein 3 height adjustment plates to determine the correct height of the rail head attached between the base 5 and the elastic plate 6 can be.

Links und rechts des Schienensteges 2 sind Lagerteile 7 angeordnet, die jeweils ein Stützteil 8 und eine elastische Lage 9 umfassen. Das Stützteil 8 liegt am Steg 2 der Schiene 20 an und ist zweckmäßigerweise mit dem Schienensteg 2 verklebt. Die Stützteile 8 sind an den zwischen dem Schienenkopf 3 und dem Schienenfuß 1 liegenden Bereich, der auch als "Laschenkammer" bezeichnet wird, angepaßt, und füllen diesen Bereich mit geringem Spiel aus.Left and right of the rail web 2 bearing parts 7 are arranged, each comprise a support part 8 and an elastic layer 9. The support part 8 lies on the web 2 of the rail 20 and is expediently glued to the rail web 2. The support parts 8 are on the between the rail head 3 and the rail foot 1 lying area, which is also referred to as a "tab chamber", adjusted, and fill this area with little play.

Die Stützteile 8 sind aus einem relativ harten und unelastischen Material hergestellt. Dieses Material soll jedoch nicht spröde sein und muß die bei der Belastung durch die bei der Verformung der Schiene 20 auftretenden Kräfte aufnehmen können, ohne zu brechen. Die Stützteile 8 könnten theoretisch auch aus Beton oder Metall hergestellt sein, doch wird ein Kunststoffmaterial für die Herstellung dieser Teile bevorzugt. So kann z.B. ein Elastomer mit hoher Steifigkeit, eventuell auch in Form eines Kautschuk-Elastomers zur Herstellung der Stützteile 8, 10 verwendet werden. Dabei ist es besonders vorteilhaft ein zelliges bzw. geschäumtes PU-Elastomer mit einer Dichte von mindestens 150 kg/m3, beispielsweise mit einer Dichte im Bereich von 250kg/m3, zu verwenden.The support parts 8 are made of a relatively hard and inelastic material. However, this material is not intended to be brittle and must be able to absorb the forces which arise during the deformation of the rail 20 without breaking. The support parts 8 could theoretically also be made of concrete or metal, but a plastic material is preferred for the production of these parts. For example, an elastomer with high rigidity, possibly also in the form of a rubber elastomer, can be used to produce the support parts 8, 10. It is particularly advantageous to use a cellular or foamed PU elastomer with a density of at least 150 kg / m 3 , for example with a density in the range of 250kg / m 3 .

Die elastischen Lagen 9 ragen über die Oberseiten der Stützteile 8 hinaus und liegen im eingebauten Zustand an den Seitenwänden des Schienenkopfes 3 an. Weiters ragen die elastischen Lagen 9 an den Unterseiten der Stützteile 7 über diese hinaus und liegen seitlich an der elastischen Platte 6 an.The elastic layers 9 protrude beyond the tops of the support parts 8 and are in the installed state on the side walls of the rail head 3. Furthermore, the elastic layers 9 protrude on the undersides of the support parts 7 these out and lie laterally on the elastic plate 6.

Die elastische Lage 9 besteht zweckmäßigerweise aus einem Elastomer, vorzugsweise aus einem elastischen Kunststoff in Form eines zelligen bzw. geschäumten PU-Elastomers. Es sind aber auch andere geschäumte Elastomere einsetzbar. Dabei sind unter dem Begriff Elastomere auch Kautschuk-Materialien im Sinne von Kautschuk-Elastomeren, beispielsweise Moosgummi, zu verstehen.The elastic layer 9 expediently consists of an elastomer, preferably made of an elastic plastic in the form of a cellular or foamed PU elastomer. But there are also other foamed elastomers used. The term elastomers also includes rubber materials in the sense of rubber elastomers, for example foam rubber.

Die Stützteile 8 übertragen Bewegungen des Schienensteges 2 und des Schienenkopfes 3 auf die elastische Lage 9, wobei diese Bewegungen von der Lage 9 aufgenommen und gedämpft werden. Dabei begrenzt der an die elastische Lage 9 seitlich anschließende Beton 11 die Bewegungen des Schienensteges 2 und damit des Schienenkopfes 3 in definierter Weise. The support parts 8 transmit movements of the rail web 2 and the rail head 3 on the elastic layer 9, these movements from the layer 9 be absorbed and damped. This limits the elastic position 9 laterally adjoining concrete 11 the movements of the rail web 2 and so that the rail head 3 in a defined manner.

An den vom Schienensteg 2 abgewandten Seitenwänden 22 der Lagerteile 7 sind fest mit den Lagerteilen 7 verbundene Montagegitter 10 angebracht. Ein solches dreidimensionales Montagegitter 10, welches sich in einem räumlichen Bereich erstreckt, der neben einer Längen- und Breitenausdehnung auch eine bestimmte Höhe H aufweist, ist in Fig. 3 schematisch dargestellt, wobei die gedachten ungefähren Begrenzungskanten der Übersichtlichkeit halber durch Linien 23 angedeutet sind. Das Gitter besteht aus räumlich verschlauften Fäden oder Schnüren 21, die vorzugsweise aus einem Kunststoff bestehen, beispielsweise PP, PA oder PE und eine gewisse Elastizität aufweisen. Solche Gitter werden beispielsweise als Drainagegitter eingesetzt und sind kommerziell erhältlich. Beispielsweise beträgt die Höhe H des Gitters etwa 10mm. Zur Befestigung des Gitters an der elastischen Lage 9 wäre es theoretisch denkbar und möglich, auf der äußeren Seitenwand 22 der elastischen Lage 9 eine relativ dicke Klebschicht aufzubringen, in welche das Montagegitter 10 eingedrückt wird. Bevorzugt ist es jedoch, das Montagegitter 10 über einen Teil seiner Höhe H, beispielsweise über etwa die Hälfte seiner Höhe H im Material der elastischen Lage 9 einzubetten. Hierzu kann das Montagegitter 10 bei der Herstellung der elastischen Lage 9 vor deren Aushärtung in das somit zähflüssige Material dieser Lage eingedrückt werden, wobei beim Aushärten des Elastomers der elastischen Lage 9 das Gitter materialschlüssig in der elastischen Lage 9 eingebunden wird.On the side walls 22 of the bearing parts 7 facing away from the rail web 2 firmly attached to the bearing parts 7 mounting grid 10. Such one three-dimensional mounting grid 10, which is in a spatial area extends, which in addition to a length and width extension also a certain Height H is shown schematically in Fig. 3, the approximate For the sake of clarity, boundary edges are indicated by lines 23 are. The grid consists of spatially looped threads or cords 21, which preferably consist of a plastic, for example PP, PA or PE and have some elasticity. Such grids are, for example, as Drainage grids are used and are commercially available. For example the height H of the grid about 10mm. To attach the grille to the elastic Layer 9 it would be theoretically conceivable and possible on the outer side wall 22 of the elastic layer 9 to apply a relatively thick adhesive layer, in which is pushed in the mounting grid 10. It is preferred, however, the mounting grid 10 over part of its height H, for example over about half to embed its height H in the material of the elastic layer 9. For this, the Mounting grid 10 in the manufacture of the elastic layer 9 before it hardens are pressed into the viscous material of this layer, whereby when the elastomer of the elastic layer 9 hardens, the mesh is material-locking is involved in the elastic layer 9.

Bei der Montage der Schienen 20 werden zunächst die elastischen Platten 6 an der Unterseite der Schienenfüße 1 angeklebt. Die linken und die rechten Lagerteile 7 werden an den Schienensteg 2 geklebt, wobei die elastische Lage 9 nach oben und unten über die Stützteile 8 übersteht. Die Schienen 20 werden durch Höhenausgleichsplatten aus Kunststoff in der Höhe nivelliert. In der Folge wird die Baugrube bis zur vorgegebenen Höhe mit Beton 11 ausgegossen, der an die elastischen Lagen 9 seitlich angrenzt und in den über die Seitenwände 22 der elastischen Lagen 9 vorstehenden Teil des Montagegitters 10 eindringt, so daß bei der Aushärtung des Betons 10 eine Verankerung der Lagerteile 7 und somit der Schiene 20 im Beton 11 erfolgt. Eine den Straßenbelag bildende Asphaltschicht 12 wird auf diese Betonschicht aufgebracht, wobei bevorzugterweise ein Spalt zum Schienenkopf 3 bzw. zur an diesem anliegenden elastischen Zwischenlage 9 verbleibt. Dieser Spalt wird anschließend mit einer Vergußmasse vergossen, welche Verbindungsstücke 13 ausbildet. Dabei ist eine bituminöse Vergußmasse bevorzugt, doch können auch andere Vergußmassen, z.B. Kunstharze verwendet werden.When installing the rails 20, the elastic plates 6 are first applied glued to the underside of the rail feet 1. The left and right bearing parts 7 are glued to the rail web 2, the elastic layer 9 after protrudes above and below on the support parts 8. The rails 20 are through Leveling plates made of plastic leveled in height. As a result poured the construction pit to the specified height with concrete 11, which to the elastic layers 9 laterally adjacent and in the over the side walls 22 of the elastic layers 9 protruding part of the mounting grid 10 penetrates so that anchoring of the bearing parts 7 and thus during the hardening of the concrete 10 the rail 20 in the concrete 11. An asphalt layer that forms the road surface 12 is applied to this layer of concrete, preferably a Gap to the rail head 3 or to the elastic intermediate layer lying against it 9 remains. This gap is then sealed with a potting compound shed which connecting pieces 13 forms. It is a bituminous Potting compound preferred, but other potting compounds, e.g. resins be used.

Auch andere Arten des Einbaus der Einrichtung sind denkbar und möglich, beispielsweise könnten auf einer Sauberkeitsschicht Schwellen ausgelegt werden, beispielsweise mit einer Länge von 10 bis 20 cm, wobei die Schienen in einer Aussparung geführt werden und an den Schwellen befestigt werden.Other types of installation of the device are also conceivable and possible, for example thresholds could be laid out on a cleanliness layer, for example with a length of 10 to 20 cm, the rails in one Recess are guided and attached to the sleepers.

Die Stützteile 8 könnten mit den elastischen Lagen 9 grundsätzlich durch eine Verklebung verbunden sein. Bevorzugt ist es jedoch, die elastische Lage 9 beidseitig überstehend in eine Form einzulegen und das den Stützteil 8 bildende Material in die Form einzugießen, wodurch eine Verbindung dieser Teile bewirkt wird, eventuell unter Zwischenschaltung von Haftlagen.The support parts 8 could in principle with the elastic layers 9 by a Be bonded. However, it is preferred that the elastic layer 9 on both sides protruding into a mold and the material forming the support part 8 Pour into the mold, connecting these parts , possibly with the interposition of detention.

Grundsätzlich wäre es denkbar und möglich, daß die Lagerteile 7 weitere Lagen oder Teile umfassen. Beispielsweise könnte an den dem Schienensteg 2 zugewandten Seiten der Stützteile 8 eine weitere Lage angebracht sein. Auch könnte an der vom Schienensteg abgewandten Seite der elastischen Lage 9 eine weitere Lage bzw. ein weiteres Stützteil angeordnet sein. Das Montagegitter 10 wäre dann an der Außenseite dieser weiteren Lage zu befestigen, wobei diese Außenseite in diesem Fall die vom Schienensteg 2 abgewandte Seitenwand 22 des Lagerteils 7 bilden würde. Basically, it would be conceivable and possible that the bearing parts 7 more layers or include parts. For example, on the rail web 2 facing A further layer may be attached to the sides of the support parts 8. Could also on the side of the elastic layer 9 facing away from the rail web Layer or another support member may be arranged. The mounting grid 10 would be then attach to the outside of this additional layer, this outside in this case the side wall 22 of the bearing part facing away from the rail web 2 7 would form.
