Description

Die Erfindung betrifft eine Vorrichtung zur Befestigung einer Schiene für Schienenfahrzeuge.The invention relates to a device for fastening a rail for rail vehicles.

WO 2007/082553 A1 beschreibt ein System zur Befestigung einer Schiene bei dem eine Schienenunterlagsplatte jeweils seitlich einer aufgesetzten Schiene von Schrauben durchgriffen wird. Die Schrauben sind in einem Fahrweg aus Beton verankert und spannen jeweils Federklemmen auf einen Fuß der Schiene, so dass sowohl die Schiene als auch die Unterlagsplatte durch die Schrauben nach unten gespannt werden. Zur Abstützung seitlich bzw. in Querrichtung wirkender Kräfte sind zudem Haltewinkel vorgesehen, die die Unterlagsplatte nur in der Querrichtung formschlüssig abstützen. Die Haltewinkel ihrerseits werden durch weitere Schrauben gegen den Fahrweg gezogen. WO 2007/082553 A1 describes a system for fixing a rail in which a rail underlay plate is in each case passed through laterally of an attached rail of screws. The screws are anchored in a concrete track and each clamp spring clips on one leg of the rail so that both the rail and the base plate are tensioned down by the screws. To support laterally or in the transverse direction acting forces bracket are also provided which support the base plate only in the transverse direction positively. The brackets themselves are pulled by other screws against the track.

DE 101 39 198 A1 beschreibt eine Schienenunterlagsplatte, die seitlich von Schrauben durchgriffen wird, wobei Federklemmen zur Festlegung der Schiene an zumindest einer der Schrauben vorgesehen sind. Zudem hat die Unterlagsplatte Vorsprünge, die in korrespondierende Rillen in einem Fahrweg formschlüssig eingreifen, um eine ausreichende seitliche Kraftabstützung zu erzielen. DE 101 39 198 A1 describes a rail underlay plate which is laterally penetrated by screws, wherein spring clamps are provided for fixing the rail to at least one of the screws. In addition, the base plate has projections which engage positively in corresponding grooves in a track in order to achieve a sufficient lateral force support.

Die WO 2015/150644 A1 offenbart eine Vorrichtung zur Befestigung einer Schiene für Schienenfahrzeuge, umfassend eine Unterlagsplatte, die an einem festen Fahrweg lösbar festgelegt ist, wobei die Schiene an der Unterlagsplatte durch Schienenhalteglieder festgelegt ist und wobei die Unterlagsplatte zu ihrer Festlegung mittels eines getrennt zu der Unterlagsplatte auf dem Fahrweg aufliegenden Halteglied von oben kraftbeaufschlagt ist.The WO 2015/150644 A1 discloses a device for fastening a rail for rail vehicles, comprising a base plate which is fixed to a Track is releasably fixed, wherein the rail is fixed to the base plate by rail holding members and wherein the base plate is subjected to its force by means of a separate from the base plate resting on the track holding member from above.

Die KR 20100067354 A offenbart ebenfalls eine Vorrichtung zur Befestigung einer Schiene für Schienenfahrzeuge, umfassend eine Unterlagsplatte, welche zu ihrer Festlegung mittels eines getrennt zu der Unterlagsplatte auf dem Fahrweg aufliegenden Halteglied von oben kraftbeaufschlagt ist. Die Schiene wird an der Unterlagsplatte durch Schienenhalteglieder festgelegt.The KR 20100067354 A also discloses a device for fastening a rail for rail vehicles, comprising a base plate, which is subjected to force from above for its determination by means of a separate from the base plate resting on the track holding member. The rail is fixed to the base plate by rail holding members.

Es ist die Aufgabe der Erfindung, eine Vorrichtung zur Befestigung einer Schiene für Schienenfahrzeuge anzugeben, die eine einfache Festlegung auf einem Fahrweg ermöglicht.It is the object of the invention to provide a device for fastening a rail for rail vehicles, which allows easy fixing on a track.

Diese Aufgabe wird für eine eingangs genannte Vorrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Durch das Vorsehen eines von der Unterlagsplatte getrennt aufliegenden Halteglieds kann das Halteglied bezüglich seiner Haltefunktion optimiert werden, so dass die Unterlagsplatte an sich in ihrer Formgebung frei bleibt.This object is achieved for an aforementioned device according to the invention with the characterizing features of claim 1. By providing a separate from the base plate resting support member, the holding member can be optimized with respect to its holding function, so that the base plate remains free in its shape.

Insbesondere können auf diese Weise Ankerglieder eingespart werden. Allgemein vorteilhaft können bei einer erfindungsgemäßen Vorrichtung nicht mehr als zwei Ankerglieder in einer Querrichtung vorgesehen sein, die in den Fahrweg eingreifen.In particular, anchor members can be saved in this way. In a device according to the invention, generally not more than two armature elements can be provided in a transverse direction, which engage in the travel path.

Die Unterlagsplatte ist vorteilhaft als Formteil hergestellt. Sie kann aus Metall, insbesondere Stahl, oder auch aus einem anderen Material wie z.B. Kunststoff bestehen. Der feste Fahrweg besteht bevorzugt, aber nicht notwendig, aus Beton. Es kann sich insbesondere um einen durchgängigen Fahrweg handeln, wie er in modernen Bauformen eines schotterlosen Oberbaus eingesetzt wird.The base plate is advantageously made as a molded part. It can be made of metal, in particular steel, or else of another material, such as e.g. Plastic exist. The solid track is preferred, but not necessary, made of concrete. In particular, it may be a continuous track, as used in modern designs of a ballastless superstructure.

Gemäß der Erfindung hat das Halteglied ein Rahmenteil, das eine reibschlüssig auf dem Fahrweg anliegende Druckfläche aufweist. Diese Druckfläche kann nach Größe und Struktur optimal an die erforderlichen Haltekräfte angepasst werden, so dass für die Unterlagsplatte eine größere Freiheit der Ausgestaltung verbleibt.According to the invention, the holding member has a frame part which has a frictionally engaging on the driveway pressure surface. This pressure surface can be optimally adapted to the required holding forces according to size and structure, so that a greater freedom of embodiment remains for the base plate.

Bevorzugt ist dabei das Rahmenteil über einen das Rahmenteil durchgreifendes Ankerglied gegen den Fahrweg verspannt. Unter einem Ankerglied wird im Sinne der Erfindung allgemein jedes auf Zug belastbare Befestigungsmittel verstanden, das in den Fahrweg eingreift und die Unterlagsplatte mit dem Fahrweg verbindet. Beispiele für bevorzugte Ankerglieder im Sinne der Erfindung sind formschlüssig in dem Fahrweg gehaltene Bolzen mit
einem Gewindekopf, Betonanker verschiedener Bauart und Schrauben. Bei Verwendung von Schrauben als Ankerglieder können diese zum Beispiel mittels Dübeln in einer Bohrung des Fahrwegs festgelegt werden.In this case, the frame part is preferably braced against the travel path via an anchor member which passes through the frame part. In the context of the invention, an anchor member is generally understood to mean any fastening means capable of being subjected to tension, which engages in the guideway and connects the underlay plate to the guideway. Examples of preferred anchor members in the context of the invention are positively held in the driveway with bolts
a threaded head, concrete anchors of various types and screws. When using screws as anchor members they can be set for example by means of dowels in a bore of the track.

Das Ankerglied übt, zum Beispiel mittels einer Schraubmutter, direkte Druckkräfte auf die Druckfläche aus, so dass sehr hohe Kräfte auf Basis eines Reibschlusses zwischen Druckfläche und Fahrwegoberfläche erzielbar sind.The anchor member exercises, for example by means of a nut, direct pressure forces on the pressure surface, so that very high forces based on a frictional engagement between the pressure surface and the track surface can be achieved.

Dabei kann vorteilhaft eine Spannklemme gegen das Rahmenteil gespannt sein, wobei die Spannklemme die Unterlagsplatte formschlüssig übergreift und federelastisch in Richtung des Fahrwegs drückt. Dies erlaubt der Unterlagsplatte eine vorteilhafte vertikale Bewegungsmöglichkeit bei entsprechenden Erschütterungen und Schwingungen. Die Andruckkraft der Unterlagsplatte kann dabei über die Auslegung der Spannklemme definiert werden, wobei die Verspannung des Rahmenteils gegenüber dem Fahrweg hierdurch nicht limitiert ist.In this case, advantageously, a tension clamp against the frame part be tensioned, wherein the tension clamp engages over the base plate form-fitting and resiliently presses in the direction of the travel path. This allows the base plate an advantageous vertical movement possibility with corresponding shocks and vibrations. The pressure force of the base plate can be defined on the design of the tension clamp, the tension of the frame part relative to the track is not limited thereby.

Um eine Position der Schiene in der Ebene parallel zu dem Fahrweg sicherzustellen, ist es vorgesehen dass das Rahmenteil die Unterlagsplatte in sowohl in einer zu der Schiene parallelen Längsrichtung als auch in einer hierzu senkrechten und zu dem Fahrweg parallelen Querrichtung formschlüssig abstützt. Hierzu kann das Rahmenteil zum Beispiel in Querrichtung stoßbündig an der Unterlagsplatte anliegen und von vorragenden Zapfen der Unterlagsplatte umgriffen werden.In order to ensure a position of the rail in the plane parallel to the track, it is provided that the frame member supports the base plate in a form-parallel both in a longitudinal direction parallel to the rail and in a direction perpendicular thereto and parallel to the track transverse direction. For this purpose, the frame part, for example, abut flush in the transverse direction of the base plate and be embraced by protruding pin of the base plate.

Allgemein vorteilhaft kann das Halteglied eine Winkelführungsplatte zur Abstützung einer Spannklemme umfassen. Dies erlaubt eine flexible Ausgestaltung bezüglich einer Höhenanpassung des Halteglieds. Im Interesse einer einfachen Realisierung kann dabei unterhalb der Winkelführungsplatte eine Distanzplatte zur vertikalen Höheneinstellung des Halteglieds angeordnet sein.Generally advantageous, the holding member may comprise an angle guide plate for supporting a tension clamp. This allows a flexible configuration with respect to a height adjustment of the holding member. In the interest of a simple realization can be arranged below the angle guide plate a spacer plate for vertical height adjustment of the support member.

Um die Unterlagsplatte einer jeweiligen Einbausituation anzupassen und um die bei einem festen Fahrweg häufig großen Toleranzen auszugleichen ist es vorteilhaft vorgesehen, dass unterhalb der Unterlagsplatte eine Distanzplatte zur vertikalen Höheneinstellung der Unterlagsplatte angeordnet ist.In order to adapt the base plate to a respective installation situation and to compensate for the tolerances which are frequently high for a fixed route, it is advantageously provided that a spacer plate for vertical height adjustment of the base plate is arranged below the base plate.

Weiterhin kann es vorgesehen sein, dass unterhalb der Unterlagsplatte zumindest eine Zwischenplatte aus einem gering steifen Material zur Dämpfungszwecken angeordnet ist. Dies erlaubt eine einfache und effektive Schalldämmung. Insbesondere erlaubt es die erfindungsgemäße Konstruktion, dass die Zwischenplatte nicht den hohen Anpresskräften eines Ankerglieds ausgesetzt ist. Ein gering steifes Material im vorliegenden Sinn ist zum Beispiel ein Kunststoff mit einer statischen Steifigkeit von weniger als 200 kN/mm.Furthermore, it can be provided that at least one intermediate plate made of a slightly rigid material is arranged below the base plate for damping purposes. This allows a simple and effective soundproofing. In particular, the construction according to the invention allows the intermediate plate not to be exposed to the high contact forces of an anchor member. A low stiffness material in the present sense is, for example, a plastic having a static stiffness of less than 200 kN / mm.

Gemäß den vorstehend beschriebenen Vorzügen ist eine erfindungsgemäße Vorrichtung besonders bevorzugt so ausgelegt, dass die Unterlagsplatte nicht von einem in dem Fahrweg aufgenommenen Ankerglied durchgriffen wird. Dies erlaubt eine Begrenzung der von oben auf die Unterlagsplatte wirkenden Montagekräfte. Besonders vorteilhaft hat der Fahrweg unter der Vorrichtung eine ebene Oberfläche ohne formschlüssig abstützende Strukturen. Dies bedeutet erhebliche Einsparungen und Vereinfachungen beim Bau des Fahrwegs und wird durch die besonderen Eigenschaften einer erfindungsgemäßen Vorrichtung ermöglicht. Weitere Vorteile und Merkmale ergeben sich aus dem nachfolgend beschriebenen Ausführungsbeispiel sowie aus den abhängigen Ansprüchen.According to the advantages described above, a device according to the invention is particularly preferably designed so that the base plate is not penetrated by an anchor member received in the track. This allows a limitation of the forces acting from above on the base plate mounting forces. Particularly advantageously, the infrastructure under the device has a flat surface without positively supporting structures. This means considerable savings and simplifications in the construction of the infrastructure and is made possible by the special properties of a device according to the invention. Further advantages and features will become apparent from the embodiment described below and from the dependent claims.

The underlay plate 1 is formed as a molded part made of steel.

Im Sinne der Erfindung verläuft die Schiene 2 in der Darstellung nach Fig. 1 in einer Längsrichtung, die senkrecht zu der Zeichnungsebene steht. Eine Querrichtung verläuft waagerecht in der Zeichnungsebene von Fig. 1. Die Gewichtskraft eines Schienenfahrzeugs wirkt in einer hierzu wiederum senkrechten Hochrichtung, wobei auch Querkräfte in der Querrichtung auftreten, zum Beispiel durch Kurvenfahrten.For the purposes of the invention, the rail 2 follows in the illustration Fig. 1 in a longitudinal direction perpendicular to the plane of the drawing. A transverse direction runs horizontally in the plane of the drawing Fig. 1 , The weight of a rail vehicle acts in a vertical direction, which in turn is vertical, whereby transverse forces also occur in the transverse direction, for example by cornering.

Vorliegend hat die Schiene 2 ein übliches Profil und befindet sich im Bereich einer Weiche, so dass zudem eine weitere, in Querrichtung verstellbare Schiene 2' auf der Unterlagsplatte 1 aufliegt.In the present case, the rail 2 has a conventional profile and is located in the region of a switch, so that in addition a further, in the transverse direction adjustable rail 2 'rests on the base plate 1.

The exact shape of the base plate 1 can be adapted to the particular use.

Die Unterlagsplatte 1 ist auf einem aus Beton gebauten Fahrweg 3 angeordnet. Der Fahrweg hat vorliegend eine glatte Oberfläche ohne Rillen oder Schultern, wie sie meist im Stand der Technik zur Abstützung von Querkräften vorgesehen sind. Dies erlaubt eine kostengünstige und einfache Anfertigung des Fahrwegs 3.The base plate 1 is arranged on a roadway 3 constructed of concrete. The track has a smooth surface without grooves or shoulders, as they are usually provided in the prior art for supporting lateral forces. This allows a cost-effective and simple production of the guideway 3.

Die Schiene 2 ist über Schienenhalteglieder 1a an der Unterlagsplatte 1 festgelegt. Dabei ist der Schienenfuß durch übliche Spannklemmen oder Spannbügel (nicht dargestellt) gegen die Unterlagsplatte 1 verspannt. Zur Festlegung der Schiene 2 an der Unterlagsplatte 1 gegebenenfalls verwendete Schrauben durchgreifen die Unterlagsplatte nicht bzw. sind nicht in dem Fahrweg 3 verankert.The rail 2 is fixed to the base plate 1 via rail holding members 1a. Here is the rail by conventional clamps or Clamp (not shown) braced against the base plate 1. To fix the rail 2 on the base plate 1 optionally used screws do not pass through the base plate or are not anchored in the track 3.

Zwischen der Unterlagsplatte 1 und dem Fahrweg befindet sich eine Zwischenplatte 4 aus einem gering steifen Material, vorliegend ein Kunststoff mit einer statischen Steifigkeit von <= 200 kN/mm. Diese Zwischenplatte 4 dient einer Stoß- und Schallentkopplung zwischen der Schiene 2 und dem Fahrweg 3.Between the base plate 1 and the track is an intermediate plate 4 made of a low-stiffness material, in this case a plastic having a static stiffness of <= 200 kN / mm. This intermediate plate 4 serves a shock and sound decoupling between the rail 2 and the track 3.

Ferner befindet sich unter der Zwischenplatte 4 noch eine optionale Distanzplatte 5 aus Metall, um eventuell vorliegende Höhentoleranzen des Fahrwegs auszugleichen. Die Distanzplatte 5 kann alternativ auch aus Kunststoff bestehen.Further, under the intermediate plate 4 is still an optional spacer plate 5 made of metal to compensate for any existing height tolerances of the infrastructure. The spacer plate 5 may alternatively be made of plastic.

Die Unterlagsplatte 1 wird über zwei Halteglieder 6 in ihrer Position fixiert. Auf jeder Seite ist jeweils eines der Halteglieder 6 in der Querrichtung stoßbündig vor einer Stirnseite der Unterlagsplatte 1 positioniert. Somit ist die Unterlagsplatte in Querrichtung formschlüssig gehalten.The base plate 1 is fixed in position via two retaining members 6. On each side of each of the holding members 6 is positioned in the transverse direction shock-flush in front of a front side of the base plate 1. Thus, the base plate is held in a form-fitting manner in the transverse direction.

Zudem Umgreifen vorragende Zapfen 1b der Unterlagsplatte 1 die Halteglieder, so dass auch eine formschlüssige Abstützung in der Längsrichtung erfolgt.In addition, projecting projecting pins 1 b of the base plate 1, the holding members, so that there is also a positive support in the longitudinal direction.

In der Hochrichtung wird die Unterlagsplatte durch Spannklemmen 7 der Halteglieder 6, die ausgehend von den Haltegliedern 6 die Enden der Unterlagsplatte 1 übergreifen, formschlüssig gehalten und mit durch die Spannklemmen definierter Kraft gegen den Fahrweg 3 gedrückt.In the vertical direction, the base plate is held by clamps 7 of the support members 6, which extend from the support members 6, the ends of the base plate 1, positively held and pressed with defined by the clamps force against the track 3.

Die Halteglieder umfassen jeweils ein unteres Rahmenteil 8, dessen Unterseite als definierte Druckfläche 8a ausgebildet ist, und mit der das Rahmenteil auf der Oberfläche des Fahrwegs 3 aufliegt.The holding members each comprise a lower frame part 8, whose underside is designed as a defined pressure surface 8a, and with which the frame part rests on the surface of the travel path 3.

Das Rahmenteil 8 hat eine zentrale Durchbrechung 8b, die von einem in dem Fahrweg auf übliche Weise festlegbaren Ankerglied 9 des Halteglieds 6 durchgriffen wird. Das Ankerglied 9 ist im vorliegenden Beispiel als formschlüssig in dem Fahrweg verankerter Bolzen mit einem Gewindekopf ausgebildet. Alternativ kann das Ankerglied 9 zum Beispiel auch als Schraube ausgebildet sein, die über einen Dübel in dem Fahrweg verankert ist.The frame member 8 has a central opening 8b, which is penetrated by a fixable in the usual manner anchor member 9 of the support member 6. The anchor member 9 is formed in the present example as a form-fitting anchored in the driveway bolt with a threaded head. Alternatively, the anchor member 9 may be formed, for example, as a screw which is anchored via a dowel in the driveway.

Über dem Rahmenteil 8 ist eine ebenfalls von dem Ankerglied 9 durchgriffene Winkelführungsplatte 10 des Halteglieds 6 angeordnet, die der definierten Führung und Abstützung der Spannklemme 7 dient. Die Spannklemme 7 ist analog zu im Gleisbau üblich verwendeten Spannklemmen ausgebildet, wobei die genaue Form, Materialstärke und Federkonstante je nach Auslegung der Unterlagsplatte angepasst sein können. Besonders zweckmäßig können Spannklemmen verwendet werden, die einer üblichen Norm entsprechen.About the frame part 8 is also an attacked by the anchor member 9 angle guide plate 10 of the support member 6 is arranged, which serves the defined guidance and support of the tension clamp 7. The tension clamp 7 is designed analogously to clamping clamps commonly used in track construction, wherein the exact shape, material thickness and spring constant can be adjusted depending on the design of the base plate. Particularly useful clamps can be used, which correspond to a standard.

Zwischen dem Rahmenteil 8 und der Winkelführungsplatte 10 ist eine optionale Distanzplatte 11 angeordnet, die analog zu der Funktion der Distanzplatte 5 eine genaue Höhenanpassung zum Toleranzausgleich ermöglicht. Im Regelfall kann die Distanzplatte 11 in Ihrer Dicke der Distanzplatte 5 entsprechen, sofern vorgesehen.Between the frame part 8 and the angled guide plate 10, an optional spacer plate 11 is arranged, which allows analogous to the function of the spacer plate 5 a precise height adjustment for tolerance compensation. As a rule, the spacer plate 11 may correspond in thickness to the spacer plate 5, if provided.

An dem Ankerglied 9 sind Mutter und Scheiben 12 vorgesehen, mit denen die Spannklemme 7 angezogen wird. Dabei wird die Spannklemme 7 bis zu einem Anschlag an der Winkelführungsplatte 10 gespannt. Hierdurch kann die Andruckkraft des Rahmenteils 8 auf den Fahrweg 3 beliebig durch das Anzugsmoment der Mutter 12 gewählt werden, ohne dass die Andruckkraft der Unterlagsplatte weiter erhöht wird.At the anchor member 9 nut and discs 12 are provided with which the tension clamp 7 is tightened. The tension clamp 7 is stretched to a stop on the angled guide plate 10. As a result, the pressing force of the frame part 8 can be arbitrarily selected on the guideway 3 by the tightening torque of the nut 12, without the pressure force of the base plate is further increased.

Entsprechend kann die Unterlagsplatte in der Hochrichtung ausweichen, sofern durch Schwingungen oder Stöße Kräfte erreicht werden, die die Federkraft der Spannklemmen 7 übersteigen.Accordingly, the base plate can dodge in the vertical direction, if forces are achieved by vibrations or shocks that exceed the spring force of the clamps 7.

Auftretende Querkräfte in der Querrichtung sind durch die Halteglieder 6 bzw. Rahmenteile 8 ausreichend abgestützt. Hierzu werden die Größe der Druckfläche 8a, der Reibungskoeffizient der Druckfläche 8a mit dem Fahrweg und das Anzugsmoment der Mutter 12 entsprechend ausgelegt.Occurring transverse forces in the transverse direction are sufficiently supported by the holding members 6 or frame parts 8. For this purpose, the size of the pressure surface 8a, the friction coefficient of the pressure surface 8a with the guideway and the tightening torque of the nut 12 are designed accordingly.

Vorliegend werden genau zwei Ankerglieder 9 zur Festlegung der Unterlagsplatte an dem Fahrweg 3 verwendet. Insbesondere werden in der Querrichtung nur zwei Ankerglieder 9 verwendet, nämlich einer an jedem Ende der Unterlagsplatte 1. Je nach Ausdehnung der Unterlagsplatte in der Längsrichtung können in der Längsrichtung auch mehrere Ankerglieder 9 hintereinander vorgesehen sein.In the present case, exactly two anchor members 9 are used for fixing the base plate to the track 3. In particular, only two anchor members 9 are used in the transverse direction, namely one at each end of the base plate 1. Depending on the expansion of the base plate in the longitudinal direction, a plurality of anchor members 9 may be provided one behind the other in the longitudinal direction.
