Abstract

In the device described a base plate provided with guide ribs for the rail flange and comprising, in the region of said ribs, anchor holes, is or can be fixed to the sleeper. Anchor pieces provided with abutments for the rail flange can be inserted in the anchor holes, against clamping elements which grip the base plate. The securing of said plates designed for fixing by rectangular-headed bolts enables an elastic fixing of the rail without screw connection, thanks to the fact the abutments are formed integrally with the anchor pieces (18) in the form of brackets (20) and project beyond the rail flange, and that the elastic clamping elements (23) can be inserted on both sides of the rail into the recesses formed between the rail flange and the anchor brackets in the longitudinal direction of the rail. Said elements (23) are applied by deformation with tension on the rail flange and anchor bracket.

Description

Die Erfindung betrifft eine Vorrichtung zum Befestigen einer Schiene nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for fastening a rail according to the preamble of patent claim 1.

Bei herkömmlichen Vorrichtungen der eingangs genannten Art, wie sie z.B. in der DE-PS 531 722 beschrieben sind, sind die Spannglieder als Blattfedern ausgebildet, die auf die Schienenfüße gelegt und beim Einschieben der Anker von den Auslegern gegen die Schienenfüße verspannt werden. Die Anker müssen dann durch Schrauben gegen ein Herausschieben aus den Verankerungsöffnungen gesichert werden. Bei dieser bekannten Vorrichtung sind zum Einbringen und zum Herausnehmen der Spannglieder in bzw. aus den Aufnahmen zwischen den Auslegern der Anker und den Schienenfüßen stets Schraubvorgänge auszuführen. Dies ist insbesondere dann nachteilig und schwierig, wenn nach Längerer Einsatzzeit die Verspannung der Schiene gelöst werden muß, da sich die Schrauben oft nicht mehr oder nur sehr schwer lösen lassen.In the case of conventional devices of the type mentioned at the outset, e.g. are described in DE-PS 531 722, the tendons are designed as leaf springs which are placed on the rail feet and braced by the brackets against the rail feet when inserting the anchor. The anchors must then be secured against being pushed out of the anchoring openings by means of screws. In this known device, screwing operations are always to be carried out for inserting and removing the tendons in or out of the receptacles between the cantilever arms and the rail feet. This is particularly disadvantageous and difficult if, after a long period of use, the bracing of the rail has to be released, since the screws can often no longer be loosened or only with difficulty.

Ausgehend von dem obigen Stand der Technik Liegt der Erfindung die Aufgabe zugrunde, die gattungsgemäße Vorrichtung so zu verbessern, daß die Spannglieder ohne Schraubarbeiten in die Aufnahmen zwischen Auslegern der Anker und den Schienenfüßen eingebracht und verspannt sowie ebenso Leicht wieder gelöst werden können, wobei neben der Spannstellung auf einfache Weise auch eine Stellung für die Spannglieder ermöglicht ist, in der sie spannungslos in den Aufnahmen gehalten sind.Based on the above prior art, the invention has for its object to improve the generic device so that the tendons without Screwing work into the receptacles between the brackets of the anchors and the rail feet can be introduced and tensioned and just as easily released again, whereby in addition to the tensioning position, a position for the tendons is also possible in which they are held without tension in the receptacles.

Die gestellte Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The object is achieved according to the invention by the characterizing features of claim 1.

Die Anker mit Ausleger werden wie die Hakenschrauben in die Verankerungsöffnungen der Führungsebenen der Unterlagplatten eingeschoben und darin gehalten. Die elastischen Spannglieder werden ohne Schraubenbefestigung zwischen dem Schienenfuß und den Auslegern der Anker eingeschraubt und bringen die gewünschte form- und/oder kraftschlüssige, elastische Verbindung zwischen der Schiene und der Unterlagplatte. Dadurch ist nicht nur der Verschleiß der Unterlagplatte eliminiert. Die Vorrichtung kann auch ohne Demontage der Unterlagplatten an bereits verlegten Schienen ohne großen Teile- und Montageaufwand nachgerüstet werden. Dies ist ein ganz entscheidender Vorteil, der Vorrichtung, da nur die Muttern der Hakenschrauben gelöst und die Hakenschrauben mit Spannklemmen aus den Verankerungsöffnungen der Führungsrippen der Unterlagplatten entfernt und die neuen Anker eingeschoben werden müssen. Das Einbringen der neuen Spannglieder kann dann mit einfachen Handhabungsgeräten erleichtert werden. Eine eindeutig gesicherte Abstützung für die Spannglieder wird hierbei dadurch erreicht, daß die Spannglieder C-förmig ausgebildet sind, sich mittig an den Auslegern der Anker und mit ihren Enden an dem Schienenfuß der Schiene abstützen.The anchors with outrigger are inserted and held in the anchoring openings of the guide levels of the base plates like the hook screws. The elastic tendons are screwed in between the rail foot and the brackets of the anchors without screw fastening and provide the desired positive and / or non-positive, elastic connection between the rail and the base plate. This not only eliminates wear on the base plate. The device can also be retrofitted to rails that have already been laid without having to dismantle the support plates, without requiring a lot of parts and assembly. This is a very decisive advantage of the device, since only the nuts of the hook screws have to be loosened and the hook screws with tension clamps have to be removed from the anchoring openings of the guide ribs of the base plates and the new anchors have to be inserted. The introduction of the new tendons can then be facilitated with simple handling devices. A clearly secured support for the tendons is achieved in that the tendons are C-shaped, supported centrally on the cantilevers of the anchors and with their ends on the rail foot of the rail.

Eine Überlastsicherung für die Spannglieder ergibt sich einfach dadurch, daß die Stirnseiten der eingebogenen Enden in der Arbeitsstellung noch in vorgegebenem Abstand zum Mittelschenkel der Spannglieder stehen. Eine definierte Arbeitsstellung für die Spannglieder ergibt sich hierbei dadurch, daß die Spannglieder mittig auf den Außenseiten konkave Rastmulden aufweisen, daß die den Spanngliedern zugekehrten Unterseiten der Ausleger der Anker als konvexe Raststege ausgebildet sind und daß die Rastmulden und die Raststege senkrecht zu der Schiene ausgerichtet sind. Die Spannglieder werden in Längsrichtung der Schiene so weit eingeschoben, bis der Raststeg des Auslegers in die Rastmulde des Spanngliedes einrastet. Bei der Einführbewegung der Spannglieder wird eine Art Führung sichergestellt, indem die Ausleger der Anker auf die Breite der Spannglieder ausgelegt und an ihren freien Enden mit einem die Dicke der Spannglieder zumindest teilweise sich überdeckenden Halterstück versehen sind. Die Spannglieder weisen zu beiden Seiten der Rastmulde in vorgegebenem Abstand auf den Außenseiten weitere Mulden auf, die mit den Raststegen der Ausleger der Anker Entspannstellungen der Spannglieder festlegen. Somit können die Spannglieder in eine Einrichtstellung gebracht und darin gehalten werden, bei der die Schiene in Längsrichtung bewegt werden kann, ohne die Teile der Vorrichtung von der Unterlagplatte lösen zu müssen. Die Rastmulden und die weiteren Mulden werden beim Biegevorgang der Flachmaterialabschnitte zu den Spanngliedern eingebracht. Für die optimale Übertragung der Spannkraft der Spannglieder auf den Schienenfuß ist es von Bedeutung, daß die Rastmulden und die weiteren Mulden beim Biegevorgang der Flachmaterialabschnitte zu den Spanngliedern eingebracht sind. Die Überlastsicherung der Spannglieder ist hierbei so ausgelegt, daß die eingebogenen Enden mit ihren Endabschnitten senkrecht zum Mittelschenkel der Spannglieder stehen und mit ihren Stirnseiten noch einen Überlastweg von etwa 2 mm zum Mittelschenkel einnehmen.An overload protection for the tendons results simply from the fact that the end faces of the bent ends are still at a predetermined distance from the middle leg of the tendons in the working position. A defined working position for the tendons results from the fact that the tendons have concave locking troughs in the center on the outside, that the undersides of the arm of the armature facing the tendons are designed as convex locking bars and that the locking troughs and the locking bars are aligned perpendicular to the rail . The tendons are inserted in the longitudinal direction of the rail until the cantilever web of the boom snaps into the recess of the tendon. During the insertion movement of the tendons, a kind of guidance is ensured in that the cantilevers of the anchors are designed for the width of the tendons and are provided at their free ends with a holder piece that at least partially overlaps the thickness of the tendons. The tendons have on both sides of the locking trough at a predetermined distance on the outer sides further troughs, which define relaxation positions of the tendons with the locking bars of the arm of the anchor. Thus, the tendons can be brought into an adjustment position and held therein, in which the rail can be moved in the longitudinal direction without having to detach the parts of the device from the base plate. The locking troughs and the other troughs are introduced into the tendons during the bending process of the flat material sections. For the optimal transmission of the clamping force of the tendons to the rail foot, it is important that the locking troughs and the other troughs are introduced into the tendons during the bending process of the flat material sections. The overload protection of the tendons is designed so that the bent The ends with their end sections are perpendicular to the central limb of the tendons and their end faces still have an overload path of approximately 2 mm to the central limb.

Weitere zweckmäßige und vorteilhafte Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor.Further expedient and advantageous refinements of the invention emerge from the subclaims.

Eine definierte Verspannstellung ergibt sich nach einer Ausgestaltung dadurch, daß der Endabschnitt des oberen Schenkels in einen Endanschlag ausläuft. Der Endanschlag verhindert ein Durchschieben des Spanngliedes zwischen dem Ausleger und dem Schienenfuß.According to one embodiment, a defined bracing position results from the fact that the end section of the upper leg ends in an end stop. The end stop prevents the tendon from slipping between the boom and the rail foot.

Das Eindrücken in die Aufnahme und das Ausdrücken aus der Aufnahme wird dadurch erleichtert, daß der Ausleger zu beiden senkrecht zur Schiene stehenden Seiten über dem Raststeg Vertiefungen zum Ansetzen eines Werkzeuges für das Ein- und Ausdrücken des Spanngliedes aufweist.The pressing into the receptacle and the pushing out of the receptacle is facilitated in that the boom has depressions on both sides perpendicular to the rail above the latching web for attaching a tool for pushing in and pushing out the tendon.

Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert. Es zeigen

  • Fig. 2 die Draufsicht auf die Befestigungsstelle in Richtung II der Fig. 1,
  • Fig. 3 in Seitenansicht ein anderes Ausführungsbeispiel für das Spannglied,

The invention is explained in more detail using an exemplary embodiment shown in the drawing. Show it
  • 1 is a side view of an attachment point between the rail and the threshold,
  • 2 shows the top view of the fastening point in the direction II of FIG. 1,
  • 3 is a side view of another embodiment of the tendon,
  • 4 is a view in which the tendon of FIG. 3 is in the insertion position,
  • 5 is a view according to FIG. 4, in which the tendon is brought into the neutralizing position, and
  • Fig. 6 is a view of FIG. 4, in which the tendon assumes the clamping position.

Wie die Fig. 1 zeigt, ist auf der Schwelle 10 die Unterlagplatte 11 befestigt und zwar mittels der Kopfschrauben 14 und der Federringe 15. Auf der Oberseite der Unterlagplatte 11 sind zwei Führungsrippen 12 angeformt, die parallel zur Schiene 32 verlaufen und in einem Abstand zueinander angeordnet sind, der der Breite des Schienenfußes 33 entspricht. Die Schiene 32 ruht über der elastischen Platte 16 auf der Schwelle 10.As shown in FIG. 1, the base plate 11 is fastened on the threshold 10 by means of the cap screws 14 and the spring washers 15. Two guide ribs 12 are formed on the top of the base plate 11, which run parallel to the rail 32 and at a distance from one another are arranged, which corresponds to the width of the rail foot 33. The rail 32 rests on the sill 10 above the elastic plate 16.

Wie aus der Draufsicht nach Fig. 2 mit der strichpunktierten Stellung des Ankers 17 gezeigt ist, kann auch der Anker 17 in die Verankerungsöffnung 13 einer mit der Schwelle 10 verbundenen Unterlagplatte 11 nachträglich eingesetzt werden. Dies ermöglicht die Nachrüstung der neuen Vorrichtung, d.h. den Ersatz der alten starren Hakenverbindung.As is shown from the top view according to FIG. 2 with the dash-dotted position of the armature 17, the armature 17 can also be subsequently inserted into the anchoring opening 13 of a base plate 11 connected to the threshold 10. This enables the new device to be retrofitted, i.e. the replacement of the old rigid hook connection.

Die Oberseite des Schienenfußes 33 und die Unterseite des Auslegers 20 des Ankers 17 bilden die Abstützpunkte für ein elastisches Spannglied 23, das in längsrichtung der Schiene 32 eingeführt wird und sich unter Verformung mit Spannung an dem Ausleger 20 und dem Schienenfuß 33 abstützt.The top of the rail foot 33 and the underside of the arm 20 of the armature 17 form the support points for an elastic tendon 23, which is inserted in the longitudinal direction of the rail 32 and is supported under deformation with tension on the arm 20 and the rail foot 33.

Steht die Oberseite des Schienenfußes 33 in einem spitzen Winkel zu der Unterseite der Schiene 32, dann werden auch die Unterseite des Auslegers 20 gegenüber der Horizontalen und die dem Spannglied 23 zugekehrte Seite des vertikalen Teils 19 des Ankers 17 gegenüber der Vertikalen um diesen Winkel geneigt, wie die Fig. 1 zeigt. Damit wird wieder eine im Querschnitt rechteckförmige Kammer für das aus einem Flachmaterialabschnitt als Biegefeder ausgebildete Spannglied 23 geschaffen. Der am freien Ende des Auslegers 20 angeformte Haltesteg 21 reicht zumindest über einen Teil der Dicke des Spanngliedes 23 und hält das Spannglied 23 in dieser Kammer.If the top of the rail foot 33 is at an acute angle to the underside of the rail 32, then the underside of the arm 20 is also inclined relative to the vertical and the side of the vertical part 19 of the armature 17 facing the tendon 23 by this angle, as Fig. 1 shows. This again creates a chamber with a rectangular cross section for the tensioning element 23, which is made of a flat material section as a spiral spring. The integrally formed on the free end of the bracket 20 retaining web 21 extends at least over a portion of the thickness of the tendon 23 and holds the tendon 23 in this chamber.

In Fig. 1 ist nur eine Befestigungsstelle auf der einen Seite der mit Mittelsteg 34 und Schienenkopf 35 versehenen Schiene 32 gezeigt. Auf der anderen Schienenseite ist pro Schwelle 10 und Schiene 32 eine weitere gleiche Befestigungsstelle mit Anker 17 und Spannglied 23 vorgesehen.1 shows only one fastening point on one side of the rail 32 provided with the central web 34 and the rail head 35. On the other side of the rail, a further identical fastening point with armature 17 and tendon 23 is provided for each threshold 10 and rail 32.

In den Fig. 3 bis 6 ist ein Ausführungsbeispiel mit einem schleifenförmigen Spannglied 40 gezeigt, das leicht in die Aufnahme zwischen dem Ausleger 20 des Ankers 17 eingebracht und auch wieder leicht aus dieser Aufnahme wieder herausgebracht werden kann, dabei aber eine hohe Spannkraft in der Verspannstellung zuläßt.3 to 6, an embodiment with a loop-shaped tendon 40 is shown, which can be easily inserted into the receptacle between the arm 20 of the armature 17 and can also be easily removed again from this receptacle, but with a high tensioning force in the tensioned position allows.

Die Fig. 3 zeigt das als Schleife ausgebildete Spannglied 40 in Seitenansicht. Dabei ist der dem Schienenfuß 33 zugekehrte untere Schenkel mit den beiden konvex gewölbten Abstützabschnitten 41 und 42 versehen. Zwischen den beiden Abstützabschnitten 41 und 42 ist das aus Flachmaterial gebogene Spannglied 40 mittig als Widerlager 43 eingebogen, wobei die konvexe Seite dem oberen, geteilten Schenkel der Schleife zugekehrt ist. Über dem mittig angeordneten Widerlager 43 überlappen sich die Endabschnitte 45 und 50 des oberen Schenkels, wobei der äußere Endabschnitt 50 auf seiner Außenseite die Rastmulde 51 für den Raststeg 22 des Auslegers 20 aufweist. Wie in Fig. 3 gestrichelt eingezeichnet ist, kann über den äußeren Endabschnitt 50 der innere Endabschnitt 45 nach innen ausgelenkt werden, bis er am Widerlager 43 anstößt. Die mit 45′ und 50′ eingezeichnete Stellung der Endabschnitte 45 und 50 entspricht der Verspannstellung, aus der über einen Überhubweg von etwa 2 mm die Überlastsicherung durch Anschlag am Widerlager 43 erreicht wird. Dieser Überhubweg ist auch erforderlich, damit der Raststeg 22 des Auslegers 20 in die Rastmulde 50 einrasten kann.3 shows the tendon 40 designed as a loop in a side view. The lower leg facing the rail foot 33 is provided with the two convexly curved support sections 41 and 42. Between the two support sections 41 and 42, the tendon 40 bent from flat material is bent in the middle as an abutment 43, the convex side facing the upper, split leg of the loop. The end sections 45 and 50 of the upper leg overlap over the centrally arranged abutment 43, the outer end section 50 having on its outside the locking trough 51 for the locking web 22 of the arm 20. As shown in dashed lines in FIG. 3, the inner end section 45 can be deflected inward via the outer end section 50 until it abuts the abutment 43. The position of the end sections 45 and 50 shown at 45 'and 50' corresponds to the bracing position from which the overload protection is achieved by a stop on the abutment 43 over an overtravel distance of approximately 2 mm. This overtravel is also necessary so that the latching web 22 of the arm 20 can snap into the latching trough 50.

Der halbkreisförmige Übergangsabschnitt 46 der Schleife geht über die parallel zueinander verlaufenden Teilbereiche 47 und 48 in den Abstützabschnitt 42 und den äußeren Endabschnitt 50 über. Diese Teilbereiche 47 und 48 stehen in einem spitzen Winkel α zur Verbindungslinie der durch die Abstützabschnitte 41 und 42 gegebenen Abstützstellen. Die äußere Abmessung zwischen den Teilbereichen 47 und 48 ist gleich oder geringfügig kleiner als der Abstand zwischen dem Raststeg 22 und der Oberseite des Schienenfußes 33. Wie die Ansicht nach Fig. 4 zeigt, kann das Spannglied 40 in der Einführstellung 40.1 in die Aufnahme zwischen dem Raststeg 22 des Auslegers 20 und dem Schienenfuß 33 eingeschoben werden. Dabei ist der Übergangsabschnitt 44 der den Abstützabschnitt 41 mit dem inneren Endabschnitt 45 verbindet, bis auf den Winkel β angehoben, so daß die Teilbereiche 47 und 48 des Übergangsabschnittes 46 nach Verstellung um einen Winkel α parallel zu der Oberseite des Schienenfußes 33 ausgerichtet sind. Die Einführbewegung des Spanngliedes 40 ist beendet, wenn der Raststeg 22 in die Zwischenrastmulde 49 eingeführt ist, die den Übergang von dem Teilbereich 48 zu dem äußeren Endabschnitt 50 bildet.The semicircular transition section 46 of the loop merges into the support section 42 and the outer end section 50 via the partial sections 47 and 48 running parallel to one another. These subregions 47 and 48 are at an acute angle α to the connecting line of the support points given by the support sections 41 and 42. The outer dimension between the sections 47 and 48 is the same or slightly smaller than the distance between the locking web 22 and the top of the rail foot 33. As the view according to FIG. 4 shows, the tensioning member 40 in the insertion position 40.1 in the receptacle between the Locking web 22 of the boom 20 and the rail foot 33 are inserted. The transition section 44, which connects the support section 41 to the inner end section 45, is raised to the angle β, so that the partial regions 47 and 48 of the transition section 46 after adjustment by an angle α parallel to the upper side of the rail foot 33 are aligned. The insertion movement of the tensioning member 40 is ended when the latching web 22 is inserted into the intermediate latching depression 49, which forms the transition from the partial area 48 to the outer end section 50.

Wie Fig. 5 zeigt, fällt das Spannglied 40 nach dem Loslassen aufgrund seines Eigengewichtes mit dem Abstützabschnitt 41 auf den Schienenfuß 33, so daß eine Neutralisierstellung 40.2 erreicht ist, in der das Spannglied 40 in der Aufnahme zwischen dem Aufleger 20 und dem Schienenfuß 33 gehalten ist, aber noch seine Entspannstellung nach Fig. 3 einnimmt.As shown in FIG. 5, the tension member 40, after being released, falls with the support section 41 onto the rail foot 33 due to its own weight, so that a neutralization position 40.2 is reached, in which the tension member 40 is held in the receptacle between the support 20 and the rail foot 33 is, but still occupies its relaxation position according to FIG. 3.

Wird das Spannglied 40 weiter in die Aufnahme eingedrückt, dann gleitet der Raststeg 22 am Endabschnitt 50 entlang und lenkt diesen und den inneren Endabschnitt 45 in Richtung zum Widerlager 43 aus, bis der Raststeg 22 in die Rastmulde 51 einrastet. Dabei führen die Endabschnitte 45 und 50 einen kleinen Überhub aus und kehren dann in die in Fig. 6 gezeigte Verspannstellung 40.3 zurück. Der äußere Endabschnitt 50 läuft in den Endanschlag 52 aus, der ein weiteres Einschieben des Spanngliedes 40 in die Aufnahme verhindert und die Endabschnitte nehmen die mit 45′ und 50′ eingezeichneten Stellungen ein, wobei die Zwischenrastaufnahme 49 wieder freiliegt.If the clamping member 40 is pressed further into the receptacle, then the latching web 22 slides along the end section 50 and deflects this and the inner end section 45 in the direction of the abutment 43 until the latching web 22 engages in the latching depression 51. The end sections 45 and 50 carry out a small overstroke and then return to the tensioning position 40.3 shown in FIG. 6. The outer end portion 50 terminates in the end stop 52, which prevents further insertion of the tension member 40 into the receptacle and the end portions assume the positions marked with 45 'and 50', the intermediate detent receptacle 49 being exposed again.

Da doch ziemlich hohe Spannkräfte aufgebracht werden müssen, sind zu beiden Seiten des Auslegers 20 über dem Raststeg 22 Ausnehmungen 36 und 37 vorgesehen, in denen sich ein Werkzeug beim Eindrücken des Spanngliedes 40 in die Aufnahme bzw. beim Herausdrücken des Spanngliedes 40 aus der Aufnahme unverrückbar abstützen kann. Dabei wird beim Herausdrücken des Spanngliedes 40 zunächst die Neutralisierstellung 40.2 nach Fig. 5 erreicht. Hebt man den Übergangsabschnitt 44 wieder bis auf den Winkel β an, dann läßt sich das Spannglied 40 in der Einführstellung 40.1 aus der Aufnahme herausziehen.Since rather high clamping forces have to be applied, recesses 36 and 37 are provided on both sides of the boom 20 above the latching web 22, in which a tool is immovable when the clamping member 40 is pressed into the receptacle or when the clamping member 40 is pressed out of the receptacle can support. When the tendon 40 is pressed out, the neutralizing position 40.2 is first 5 reached. If the transition section 44 is raised again to the angle β, then the tensioning member 40 can be pulled out of the receptacle in the insertion position 40.1.

Es bleibt noch zu erwähnen, daß die Verankerungsöffnung 13 für den Fuß 18 des Ankers 17 auch in einer anders gestalteten Zwischenplatte eingebracht sein kann, die zwischen der Schwelle 10 und der Schiene 32 angeordnet ist. Die Verankerungsöffnung 13 kann aber auch direkt in die Schwelle 10 eingelassen sein.It remains to be mentioned that the anchoring opening 13 for the foot 18 of the armature 17 can also be introduced in a differently designed intermediate plate which is arranged between the threshold 10 and the rail 32. However, the anchoring opening 13 can also be embedded directly in the threshold 10.
