Description

BEFESTIGUNGSVORRICHTUNG FÜR EISENBAHNSCHIENEN FASTENING DEVICE FOR RAILWAY RAILS
Die Erfindung betrifft eine Befestigungsvorrichtung für Eisenbahnschienen, mit einer die Schiene abstützenden, auf einem Gleisunterbau zu befestigenden Rip- penplatte, die Rippen aufweist, zwischen denen die Schiene mit ihrem Schienenfuß aufgenommen ist.The invention relates to a fastening device for railroad tracks, with a rib plate which supports the rail and is to be fastened on a track substructure and which has ribs between which the rail is received with its rail foot.
Bei herkömmlichen Befestigungsvorrichtungen dieser Art ist die Rippenplatte beispielsweise mit Bolzen auf Eisenbahnschwellen aus Holz oder Beton veran- kert. Die beiderseits des Schienenfußes von der Rippenplatte vorspringenden Rippen legen die Querposition der Schiene fest. Eine Justiereinrichtung, beispielsweise in der Form von Exzentern, mit denen die Bolzen in der Rippenplatte gelagert sind, ermöglicht eine Seitenjustierung der Schiene. Der Schienenfuß wird auf beiden Seiten von starken Spannfedern übergriffen, die den Schienen- fuß gegen die Rippenplatte spannen. Die Spannfedern sind ihrerseits auf der Rippenplatte befestigt, beispielsweise mit Hakenschrauben, die auf oder in der Rippenplatte verankert sind und sich jeweils durch einen schleifenförmigen Teil der Spannfeder erstrecken, so daß die Spannfeder mit Hilfe einer auf die Hakenschraube aufgeschraubten Mutter gespannt werden kann. Die Rippenplatte bil- det dann zugleich auch einen Sitz für die Spannfedern. Häufig ist unter der Rippenplatte eine schall- und vibrationsdämpfende Zwischenlage angeordnet, und auch zwischen der Rippenplatte und dem Schienenfuß kann eine Einlage aus schall- und vibrationsdämpfendem Material vorgesehen sein.In conventional fastening devices of this type, the ribbed plate is anchored, for example, with bolts on railway sleepers made of wood or concrete. The ribs projecting from the ribbed plate on both sides of the rail foot determine the transverse position of the rail. An adjustment device, for example in the form of eccentrics with which the bolts are mounted in the ribbed plate, enables the rail to be adjusted laterally. The rail foot is gripped by strong tension springs on both sides, which tension the rail foot against the ribbed plate. The tension springs are in turn attached to the ribbed plate, for example with hook screws which are anchored on or in the ribbed plate and each extend through a loop-shaped part of the tension spring, so that the tension spring can be tensioned with the aid of a nut screwed onto the hook screw. The ribbed plate then also forms a seat for the tension springs. A sound and vibration damping intermediate layer is often arranged under the rib plate, and an insert made of sound and vibration damping material can also be provided between the rib plate and the rail foot.
Bisher wird die Rippenplatte durch ein massives Bauteil aus Stahl, beispielsweise aus Gußstahl gebildet. Aufgrund der vielfältigen Funktionen, die die Rippenplatte zu erfüllen hat, muß sie jedoch eine relativ komplexe Form aufweisen, so daß die Herstellung der Rippenplatte relativ kostspielig ist.So far, the ribbed plate has been formed by a solid component made of steel, for example cast steel. However, due to the various functions that the ribbed plate has to perform, it must have a relatively complex shape, so that the ribbed plate is relatively expensive to manufacture.
Aufgabe der Erfindung ist es, eine kostengünstigere Befestigungsvorrichtung zu schaffen, die eine einfache und sichere Befestigung der Eisenbahnschienen auf dem Gleisunterbau ermöglicht.The object of the invention is to provide a less expensive fastening device which enables simple and safe fastening of the railroad tracks to the track substructure.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Rippenplatte ein gezogenes Blechteil ist. Erfindungsgemäß werden somit die verschiedenen Funktionsteile der Rippenplatte, insbesondere die zur Positionierung des Schienenfußes dienenden Rippen sowie ggf. die Sitze für die Spannfedern, die Aufnahmen für Hakenschrauben oder sonstige Einrichtungen zum Spannen der Spannfedern sowie die Öffnungen oder Lager für die Bolzen bzw. die Justiereinrichtung in rationeller Weise durch Ziehen eines einstückigen Blechteils hergestellt. Auf diese Weise werden die Kosten und der Materialverbrauch für die Rippenplatte beträchtlich gesenkt, und die benötigten Funktionsteile der Rippenplatte lassen sich durch Ziehen präzise in der gewünschten Form herstellen.This object is achieved in that the rib plate is a drawn sheet metal part. According to the invention, the various functional parts of the ribbed plate, in particular the ribs used for positioning the rail foot, and possibly the seats for the tension springs, the receptacles for hook screws or other devices for tensioning the tension springs, and the openings or bearings for the bolts or the adjusting device are thus in rationally produced by pulling a one-piece sheet metal part. In this way, the cost and material consumption for the ribbed plate are considerably reduced, and the required functional parts of the ribbed plate can be precisely produced in the desired shape by drawing.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous refinements of the invention result from the subclaims.
Bevorzugt hat die Rippenplatte die Form einer sich nach unten öffnenden Scha- le, deren Hohlraum mit einem vibrationsdämmenden Material, beispielsweise mit Kunststoff, ausgefüllt ist. In einer besonders vorteilhaften Ausführungsform wird der durch die Schale gebildete Hohlraum im Kunststoff-Spritzgießverfahren mit Kunststoff ausgespritzt, so daß die Rippenplatte und die Füllung des Hohlraums ein Nerbundmaterial bilden. Die Füllung hat nicht nur vibrationsdämp- fende Eigenschaften, sondern bewirkt auch eine erwünschte Nersteifung der tiefgezogenen Rippenplatte.The ribbed plate preferably has the shape of a shell opening downwards, the cavity of which is filled with a vibration-damping material, for example with plastic. In a particularly advantageous embodiment, the cavity formed by the shell is injection-molded with plastic using the plastic injection molding process, so that the ribbed plate and the filling of the cavity form a non-composite material. The filling not only has vibration-damping properties, but also provides the desired ner stiffening of the deep-drawn ribbed plate.
Sofern unter der Rippenplatte eine vibrationsdämpfende Zwischenlage vorgesehen ist, kann diese ebenfalls angespritzt und - in einer besonders zweckmäßigen Ausführungsform - in einem Stück mit der Füllung der Rippenplatte ausgebildet werden. Entsprechend kann auch eine vibrationsdämpfende Einlage auf der Oberseite der Rippenplatte in dem Zwischenraum zwischen den Rippen in einem Arbeitsgang mit angespritzt werden.If a vibration-damping intermediate layer is provided under the rib plate, this can also be molded on and - in a particularly expedient embodiment - can be formed in one piece with the filling of the rib plate. Correspondingly, a vibration-damping insert on the top of the rib plate in the space between the ribs can also be injected in one operation.
Die Rippen haben vorzugsweise die Form von länglichen, im wesentlichen pyra- midenstumpfförmigen Ausstülpungen und können zugleich als Nerankerungs- stellen für Hakenschrauben oder sonstige Befestigungsmittel für die Spannfedern ausgebildet sein. Wahlweise können die Nerankerungsstellen für die Hakenschrauben und dergleichen jedoch auch getrennt von den Rippen in der tief- gezogenen Rippenplatte ausgebildet sein. Durchbrüche für Hakenschrauben, Bolzen und sonstige Befestigungsmittel können durch entsprechende Ausstanzungen in der Rippenplatte gebildet werden und lassen sich mit einem geeigneten Zieh- und Stanzwerkzeug in einem Arbeitsgang während des Ziehprozesses herstellen.The ribs are preferably in the form of elongated, essentially truncated pyramid-shaped protuberances and can at the same time be designed as anchor points for hook screws or other fastening means for the tension springs. Alternatively, the anchor points for the hook screws and the like can also be formed separately from the ribs in the deep-drawn rib plate. Breakthroughs for hook screws, bolts and other fasteners can be formed by punching the ribbed plate accordingly and can be produced in one operation with a suitable drawing and punching tool during the drawing process.
Sofern eine durch Exzenter gebildete Justiervorrichtung für die Seitenjustierung der Schiene vorgesehen ist, werden die Lager für die Exzenter durch tiefgezogene Hülsen gebildet, die in einem Stück an der Rippenplatte ausgebildet sind.If an adjusting device formed by an eccentric is provided for the lateral adjustment of the rail, the bearings for the eccentric are formed by deep-drawn sleeves which are formed in one piece on the ribbed plate.
Üblicherweise ist die zwischen den Rippen auf der Oberseite der Rippenplatte gebildete Stützfläche, auf der sich der Schienenfuß abstützt, nicht genau waagerecht orientiert, sondern sie hat eine gewisse Neigung. Auch dies läßt sich bei der erfindungsgemäßen Vorrichtung dadurch erreichen, daß man der Rippenplatte beim Ziehen eine geeignete, insgesamt keilförmige Gestalt gibt.Usually, the support surface formed between the ribs on the top of the rib plate, on which the rail foot is supported, is not exactly horizontally oriented, but has a certain inclination. This can also be achieved in the device according to the invention by giving the ribbed plate a suitable, overall wedge-shaped shape when pulled.
In DE-U-201 02 160 hat der Anmelder eine Vorrichtung zur Justierung einer Schiene auf einem Gleisunterbau beschrieben, die auch eine Höhenjustierung der Schiene ermöglicht. Wahlweise kann die hier beschriebene Rippenplatte auch Teil einer solchen Justiervorrichtung sein.In DE-U-201 02 160, the applicant has described a device for adjusting a rail on a track substructure, which also enables height adjustment of the rail. Optionally, the ribbed plate described here can also be part of such an adjustment device.
Im folgenden werden Ausführungsbeispiele anhand der Zeichnung näher erläutert.Exemplary embodiments are explained in more detail below with reference to the drawing.

Fig. 4 und 5 Teilschnitte durch Rippenplatten gemäß weiteren Ausführungsbeispielen. In Figur 1 ist ein Abschnitt einer Schiene 10 dargestellt, die sich mit ihrem Schienenfuß 12 auf einer Rippenplatte 14 abstützt. Die Rippenplatte 14 ist ihrerseits mit Bolzen 16, von denen in Figur 1 nur die Köpfe zu erkennen sind, auf einem Gleisunterbau 18 befestigt, der im gezeigten Beispiel durch ein flaches, durchgehendes Gleisbett aus Beton gebildet wird. Zwischen der Rippenplatte 14 und dem Gleisunterbau 18 ist eine Zwischenlage 20 aus schall- und vibrations- dämpfendem Material eingefügt.4 and 5 partial sections through rib plates according to further embodiments. 1 shows a section of a rail 10 which is supported with its rail foot 12 on a ribbed plate 14. The ribbed plate 14 is in turn fastened with bolts 16, of which only the heads can be seen in FIG. 1, to a track substructure 18, which in the example shown is formed by a flat, continuous track bed made of concrete. Between the ribbed plate 14 and the track substructure 18, an intermediate layer 20 made of sound and vibration-damping material is inserted.
Die Rippenplatte 14 wird durch ein Tiefziehteil in der Form einer nach unten ge- öffneten Schale aus Blech gebildet und weist an der Oberseite zwei erhabene, pyrarnidensturnpfförmige Rippen 22 mit leicht gerundeten Kanten auf, die den Schienenfuß 12 zwischen sich aufnehmen und so die Querposition der Schiene 10 festlegen. In jeder Rippe 22 ist eine Hakenschraube 24 verankert, die eine Spannfeder 26 bekannter Bauart durchsetzt. Die Spannfeder 26 stützt sich in einer Position, die in Querrichtung der Schiene 10 weiter außen liegt als die Position der Hakenschraube 24, auf einem durch die Rippenplatte 14 gebildeten Plateau 28 ab und wird durch eine auf die Hakenschraube 24 aufgeschraubte Mutter 30 fest gegen den Schienenfuß 12 gespannt.The ribbed plate 14 is formed by a deep-drawn part in the form of a sheet metal shell which is open at the bottom and has on the top two raised, pyrarnide-shaped ribs 22 with slightly rounded edges, which receive the rail foot 12 between them and thus the transverse position of the rail Set 10. A hook screw 24 is anchored in each rib 22 and passes through a tension spring 26 of a known type. The tension spring 26 is supported in a position which is further outside in the transverse direction of the rail 10 than the position of the hook screw 24 on a plateau 28 formed by the rib plate 14 and is firmly against the rail foot by a nut 30 screwed onto the hook screw 24 12 excited.
Jeder der Bolzen 16 erstreckt sich durch einen Exzenter 32, der in einem durch die Rippenplatte 14 gebildeten Lager drehbar ist. Die Exzenter 32 bilden eine Justiervorrichtung, die es ermöglicht, die Rippenplatte 14 und damit die Schiene 10 relativ zu den Bolzen 16 und zum Gleisunterbau 18 in Querrichtung zu verstellen.Each of the bolts 16 extends through an eccentric 32 which is rotatable in a bearing formed by the rib plate 14. The eccentrics 32 form an adjusting device which makes it possible to adjust the rib plate 14 and thus the rail 10 in the transverse direction relative to the bolts 16 and to the track substructure 18.
In der Schnittdarstellung in Figur 2 ist die genaue Form der durch ein Tiefziehteil gebildeten Rippenplatte 14 deutlicher zu erkennen. Diese Rippenplatte weist einen umlaufenden Rand 34 auf, mit dem sie sich auf der Zwischenlage 20 abstützt. Die Rippenplatte hat somit insgesamt die Form einer sich nach unten öff- nenden Schale, aus der die Rippen 22 beim Tiefziehen nach oben herausgedrückt wurden. In Höhe der Schnittebene in Figur 2 weist jede Rippen 22 an der Oberseite und an der Außenseite einen beim Tiefziehen ausgestanzten Durchbruch 36 auf, der das Einhaken des Kopfes 38 der Hakenschraube 24 ermöglicht, wie in Figur 3 dargestellt ist. Der Kopf 38 der Hakenschraube hat in der Ansicht gemäß Figur 3 einen etwa kreissegmentförmigen Querschnitt, und die obere Wand der Rippe 22 ist beim Tiefziehen so verformt worden, daß sie eine zu diesem Querschnitt komplementäre Form annimmt, so daß eine einfache Zen- trierung der Hakenschraube 24 ermöglicht wird.In the sectional view in FIG. 2, the exact shape of the rib plate 14 formed by a deep-drawn part can be seen more clearly. This ribbed plate has a peripheral edge 34 with which it is supported on the intermediate layer 20. The rib plate thus has the overall shape of a shell opening downwards, from which the ribs 22 were pressed upwards during deep drawing. At the level of the sectional plane in FIG. 2, each rib 22 has on the top and on the outside an opening 36 punched out during deep drawing, which enables the head 38 of the hook screw 24 to be hooked in, as shown in FIG. In the view according to FIG. 3, the head 38 of the hook screw has an approximately circular segment-shaped cross section, and the upper wall of the rib 22 has been deformed during deep drawing so that it assumes a shape complementary to this cross section, so that a simple zen Trierung the hook screw 24 is made possible.
Wie weiterhin in Figur 2 zu erkennen ist, werden Lagerbuchsen 40 für die Exzenter 32 durch zylindrische Hülsen gebildet, die beim Tiefziehen der Rippen- platte 14 nach unten eingezogen wurden und deren Boden ausgestanzt und entfernt wurde. Auch die Lagerbuchsen 40 stützen sich mit ihrem unteren Rand auf der Zwischenlage 20 ab.As can also be seen in FIG. 2, bearing bushes 40 for the eccentrics 32 are formed by cylindrical sleeves which were drawn down during the deep-drawing of the rib plate 14 and the bottom of which was punched out and removed. The bearing bushes 40 are also supported with their lower edge on the intermediate layer 20.
Das Innere der schalenförmigen Rippenplatte 14 ist mit einer Füllung 42 aus ei- nem vorzugsweise elastischen synthetischen Material, beispielsweise aus Kunststoff ausgefüllt. Die Füllung 42 wird vorzugsweise dadurch gebildet, daß die schalenförmige Rippenplatte 14 im Spritzgießverfahren mit dem Kunststoff ausgespritzt wird. Entsprechend kann auch auf der Oberseite der Rippenplatte 14 im Bereich zwischen den beiden Rippen 22 eine schall- und vibrationsdämpfen- de Einlage 44 aus Kunststoff anspritzt werden.The inside of the shell-shaped rib plate 14 is filled with a filling 42 made of a preferably elastic synthetic material, for example made of plastic. The filling 42 is preferably formed in that the shell-shaped rib plate 14 is injection-molded with the plastic. Correspondingly, a sound and vibration-damping insert 44 made of plastic can also be molded onto the top of the rib plate 14 in the area between the two ribs 22.
Während die Zwischenlage 20 eine gleichbleibende Dicke hat und den unteren Rand der Rippenplatte 14 in einer waagerechten Position abstützt, hat die von der Einlage 44 bedeckte Oberseite der Rippenplatte 14 ein leichtes Gefälle nach rechts in Figur 2, so daß die Schiene 10 wie üblich in einer etwas geneigten Position auf der Rippenplatte 14 abgestützt wird.While the intermediate layer 20 has a constant thickness and supports the lower edge of the rib plate 14 in a horizontal position, the upper side of the rib plate 14 covered by the insert 44 has a slight slope to the right in FIG. 2, so that the rail 10, as usual, in one somewhat inclined position is supported on the fin plate 14.
Durch die Füllung 42 ist die Rippenplatte 14 so ausgesteift, daß die Gewichtskraft der Schiene 10 und des darüber fahrenden Schienenfahrzeugs stabil auf- genommen werden kann. Die Füllung 22 füllt das Innere der schalenförmigen Rippenplatte 14 vollständig aus, mit Ausnahme von Aussparungen, in den Bereichen der Rippen 22, die die Köpfe 38 der Hakenschrauben 24 aufnehmen.The rib plate 14 is stiffened by the filling 42 in such a way that the weight of the rail 10 and the rail vehicle traveling above it can be absorbed in a stable manner. The filling 22 completely fills the interior of the bowl-shaped rib plate 14, with the exception of recesses, in the regions of the ribs 22 which accommodate the heads 38 of the hook screws 24.
Die Bolzen 16 sind jeweils mit einem gewindefreien Schaft drehbar in dem zuge- hörigen Exzenter 32 gelagert und weisen unterhalb des Schaftes einen Gewindeabschnitt 46 auf, mit dem sie in einen zugehörigen Dübel 48 eingeschraubt sind, der zuvor im Gleisunterbau 18 verankert wurde.The bolts 16 are each rotatably mounted in the associated eccentric 32 with a thread-free shaft and have a threaded section 46 below the shaft, with which they are screwed into an associated dowel 48, which was previously anchored in the track substructure 18.
Die Zwischenlage 20 liegt verschiebbar auf einer dünnen Abschlußplatte 50 auf, die nach unten umgebördelte Öffnungen 52 für den Durchtritt der Bolzen 16 aufweist. Durch die nach unten umgebördelten Ränder der Öffnungen 52 ist die Abschlußplatte 50 auf die Achsen der Dübel 48 zentriert.The intermediate layer 20 lies displaceably on a thin end plate 50 which has openings 52 flanged downwards for the passage of the bolts 16. Due to the flanged edges of the openings 52 is the End plate 50 centered on the axes of the dowels 48.
Beim Verlegen der Schiene 10 kann beispielsweise wie folgt vorgegangen werden. Zunächst wird das Gleisbett betoniert, das hier den kompletten Schienenunter- bau 18 bildet. Die Dübel 48 weisen ein sehr grobes Außengewinde auf und werden in den noch feuchten Beton des Gleisbettes eingeschraubt, so daß sie nach dem Aushärten des Betons fest im Gleisbett verankert sind, wie in der Patentanmeldung DE 100 54 041 des Anmelders beschrieben wird. Anschließend werden die Abschlußplatte 50, die Zwischenlage 20 und die Rippenplatte 14 auf das Gleisbett aufgelegt und mit Hilfe der Bolzen 16 provisorisch fixiert. Danach werden die Schienen 10 verlegt.When laying the rail 10, for example, the procedure can be as follows. First, the track bed is concreted, which forms the complete rail substructure 18 here. The dowels 48 have a very coarse external thread and are screwed into the still wet concrete of the track bed, so that they are firmly anchored in the track bed after the concrete has hardened, as described in the applicant's patent application DE 100 54 041. The end plate 50, the intermediate layer 20 and the ribbed plate 14 are then placed on the track bed and provisionally fixed with the aid of the bolts 16. The rails 10 are then laid.
Die Hakenschrauben 24 werden jeweils von außen in die Durchbrüche 36 der Rippen 22 eingehakt, und die Spannfedern 26 werden mit den Muttern 30 gegen den Schienenfuß 12 gespannt. Die Schiene 10 wird anschließend vermessen, und erforderlichenfalls wird ihre Querposition mit Hilfe der Exzenter 32 justiert. Danach werden die Bolzen 26 fest angezogen, um die Schiene 10 endgültig auf dem Gleisunterbau 18 zu fixieren.The hook screws 24 are each hooked into the openings 36 of the ribs 22 from the outside, and the tension springs 26 are tensioned with the nuts 30 against the rail foot 12. The rail 10 is then measured and, if necessary, its transverse position is adjusted using the eccentric 32. Then the bolts 26 are tightened in order to finally fix the rail 10 on the track substructure 18.
Das beschriebene Ausführungsbeispiel läßt sich auf vielfältige Weise abwandeln. Beispielsweise kann die Zwischenlage 20 auch in einem Stück mit der Füllung 42 ausgebildet und an die Rippenplatte 14 angespritzt werden.The described embodiment can be modified in a variety of ways. For example, the intermediate layer 20 can also be formed in one piece with the filling 42 and molded onto the ribbed plate 14.
Während weiterhin im gezeigten Ausführungsbeispiel die Verankerungsstellen für die Hakenschrauben 24 in die Rippen 22 integriert sind, können diese Verankerungsstellen wahlweise auch gesondert auf der Rippenplatte ausgebildet werden. Durch die Herstellung im Tiefziehverfahren läßt sich dies ohne nennenswerten Herstellungsaufwand bewerkstelligen.While the anchoring points for the hook screws 24 are also integrated in the ribs 22 in the exemplary embodiment shown, these anchoring points can optionally also be formed separately on the rib plate. By manufacturing in the deep-drawing process, this can be accomplished without any significant manufacturing effort.
Für die Befestigung der Spannfedern 26 können anstelle der Hakenschrauben 24 auch andere Befestigungsmittel vorgesehen sein, beispielsweise Gewindestifte, die in tiefgezogene Buchsen der Rippenplatte 14 eingesteckt oder eingeschraubt werden. Im letzteren Fall braucht lediglich ein Gewinde in die Buchsen eingeschnitten zu werden.For the fastening of the tension springs 26 other fastening means can also be provided instead of the hook screws 24, for example grub screws, which are inserted or screwed into deep-drawn bushings of the ribbed plate 14. In the latter case, only a thread needs to be cut into the bushings.
In einer anderen Ausführungsform sind anstelle der Hakenschrauben 24 normale Kopfschrauben oder Hammerkopfschrauben vorgesehen, die von unten in entsprechende Öffnungen der Rippenplatte 14 eingesteckt werden, bevor das Innere der Rippenplatte mit der Füllung 42 ausgespritzt wird. Die Köpfe der Schrauben können dabei in die Füllung 42 eingespritzt werden, oder es werden in der Füllung 42 Öffnungen ausgepart, durch die die Schrauben später von un- ten hindurch gesteckt werden.In another embodiment, instead of the hook screws 24, normal head screws or hammer head screws are provided, which are screwed in from below Corresponding openings of the fin plate 14 are inserted before the interior of the fin plate with the filling 42 is sprayed out. The heads of the screws can be injected into the filling 42, or openings in the filling 42 are left open, through which the screws are later inserted from below.
Figuren 4 und 5 zeigen Ausführungsformen der Rippenplatte 14, bei denen es möglich ist, die Spannfedern 26 vor dem Verlegen der Schiene 10 provisorisch an der Rippenplatte zu befestigen, so daß die Rippenplatte mit vormontierten Spannfedern ausgeliefert werden kann.Figures 4 and 5 show embodiments of the ribbed plate 14, in which it is possible to temporarily fix the tension springs 26 to the ribbed plate before the rail 10 is installed, so that the ribbed plate can be delivered with preassembled tension springs.
Bei der Ausführungsform nach Figur 4 sind zu diesem Zweck im Bereich der Plateaus 28, auf denen die Spannfedern 26 aufliegen, Klemmfedern 54 vorgesehen, die aus der Rippenplatte 14 herausgedrückt sind und einen unteren Schenkel der Spannfeder übergreifen, so daß die Spannfeder klemmend in Position gehalten wird. Im Anlieferungszustand ist die Spannfeder 26 in die in Figur 4 in durchgezogenen Linien eingezeichnete Position zurückgeklappt, so daß das Verlegen der Schiene 10 nicht behindert wird. Zur Befestigung der Schiene braucht die Spannfeder dann lediglich auf den Schienenfuß 12 geschwenkt und mit Hilfe der Mutter 30 angezogen zu werden.In the embodiment according to FIG. 4, clamping springs 54 are provided for this purpose in the area of the plateaus 28, on which the tension springs 26 rest, which are pressed out of the ribbed plate 14 and overlap a lower leg of the tension spring, so that the tension spring is held in position by clamping becomes. In the delivery state, the tension spring 26 is folded back into the position shown in solid lines in FIG. 4, so that the laying of the rail 10 is not hindered. To fasten the rail, the tension spring then only needs to be pivoted onto the rail foot 12 and tightened with the aid of the nut 30.
Bei der Ausführungsform nach Figur 5 sind die Klemπifedern 54 durch federnde Zungen 56 ersetzt, die in einem Stück an die Füllung 42 angespritzt sind und durch Öffnungen der Plateaus 28 nach oben ragen.In the embodiment according to FIG. 5, the clamping springs 54 are replaced by resilient tongues 56, which are molded onto the filling 42 in one piece and protrude upward through openings in the plateaus 28.
Gemäß einer weiteren Ausführungsform ist es auch möglich, ein Kunststoffteil, das die federnden Zungen 56 oder eine vergleichbare Klemmeinrichtung bildet, in einem Arbeitsgang mit der Einlage 44 an der Oberseite der Rippenplatte 14 anzuspritzen. According to a further embodiment, it is also possible to inject a plastic part, which forms the resilient tongues 56 or a comparable clamping device, in one operation with the insert 44 on the upper side of the rib plate 14.
