Description

Die Erfindung betrifft einen hochelastischen elektrisch isolierenden Stütz-punkt für mit Verankerungen auf einer Tragkonstruktion zu verankernde Schienen eines Gleises für spurgeführte Fahrzeuge gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a highly elastic, electrically insulating support point for rails to be anchored to a supporting structure of a track for track-guided vehicles according to the preamble of patent claim 1.

Von heutigen Schienenbefestigungen wird erwartet, dass sie zuverlässig, sicher und wartungsfrei sind, bei langem Federweg, hoher Spannkraft, großem Durchschubwiderstand und wirkungsvollem Kippschutz. Außerdem sollte eine vollautomatische Gleisverlegung durch Vormontage aller Teile im Schwellenwerk möglich sein.Today's rail fasteners are expected to be reliable, safe and maintenance-free with long travel, high clamping force, high push-through resistance and effective anti-tip protection. In addition, a fully automatic track laying should be possible by pre-assembly of all parts in sleeper.

Es sind Schienen-Befestigungssysteme bekannt, bei denen beidseits des Schienenfußes nur jeweils eine Schraube in der Unterschwellung verankert ist, wobei eine Schwellenschraube in einen Kunststoff-Dübel, der in der Beton-Unterschwellung vergossen Ist, einschraubbar ist. Dazu gehört z.B. das Vossloh System 300 mit Spannklemme für Feste Fahrbahnen, offenbart durch die Firma Vossloh Rail Systems im internet unter http://www.vossloh-rail-systems.de am 12.05.2004 um 13:57:54 Uhr mit dem Titel "Oberbau 300 mit Spannklemme Ski 15". Eine oder mehrere hochelastische Zwischenplatten unter dem Schienenfuß ersetzen die Elastizität des Schotterbettes. Zur besseren Lastverteilung auf diese, lose auf der Unterschwellung angeordneten Zwischenplatten dient eine sandwichartig eingeschobene stählerne Druckverteilungsplatte, auf der unter Zwischenschaltung üblicher Zwischenlagen die Schiene ruht. Die Winkelführungsplatte, die zur Führung der Seite des Schienenfußes und der rückwärtigen Auflagerung für die Spannklemme zur federnden Verspannung des Schienenfußes dient, ist entsprechend dick ausgeführt. Die Schienenbefestigungsschraube durchgreift also die Winkelführungsplatte und fixiert diese im Rahmen der groben Toleranzen in ihrer Lage sowie die Spannklemme auf dem Schienenfuß. Der rückwärtige Teil der Spannklemme stützt sich auf der Winkelführungsplatte ab und nimmt daher Reaktionskräfte auf, die sich aus der Einsenkung des Schienenfußes und der daraus resultierenden Bewegung der Federschlaufe auf dem Schienenfuß auf. Diese Schienen-Befestigungssysteme können in der Höhe und in der Spurweite regulierbar gestaltet sein.There are rail fastening systems are known in which both sides of the rail foot only one screw is anchored in the undercut, a sleeper screw in a plastic dowel that is cast in the concrete sub-swelling, is screwed. This includes, for example Vossloh System 300 with tension clamp for slab track, disclosed by the company Vossloh Rail Systems on the internet at http://www.vossloh-rail-systems.de on 12.05.2004 at 13:57:54 with the title "Oberbau 300 mit Spannklemme Ski 15". One or more highly elastic intermediate plates under the rail foot replace the elasticity of the ballast bed. For better load distribution on this, arranged loosely on the sub-swelling intermediate plates is a sandwiched inserted steel pressure distribution plate, resting on the interposition of conventional liners the rail. The angled guide plate, which serves to guide the side of the rail foot and the rear bearing for the tension clamp for resilient clamping of the rail foot, is made correspondingly thick. The rail fastening screw thus passes through the angled guide plate and fixes it in the context of coarse tolerances in their position and the tension clamp on the Rail. The rear part of the clamp is supported on the angled guide plate and therefore absorbs reaction forces resulting from the depression of the rail foot and the resulting movement of the spring loop on the rail foot. These rail fastening systems can be designed adjustable in height and in the gauge.

Die stählerne Platte begrenzt durch ihre Druckverteilungswirkung die Einsenkung der Schiene auf der Unterschwellung bzw. Tragkonstruktion bei Belastung durch überrollende Fahrzeuglasten und somit die Elastizität des Schienenstützpunktes insgesamt. Demgemäß ist der Federweg am Schienenfuß sehr gering und an der rückwärtigen Auflagerseite der Feder auf der Winkelführungsplatte noch geringer.The steel plate limited by their pressure distribution effect, the depression of the rail on the sub-swelling or support structure under load by rolling over vehicle loads and thus the elasticity of the rail support as a whole. Accordingly, the spring travel on the rail foot is very low and even lower on the rear bearing side of the spring on the angled guide plate.

Ähnlich gestaltet ist der Oberbau Vossloh System W14"Oberbau W 14 mit Spannklemme Skl 14", offenbart im internet unter http://www.vossloh-railsystems.de am 12.05.2004 um 13:57:04 Uhr für Betonschwellen, die üblicherweise auf Schotterbetten liegen. Das Schotterbett wirkt elastisch, sodass bei dieser Bauweise keine dickeren elastischen Unterlagen oder Zwischenplatten erforderlich sind.Similarly designed is the Superstructure Vossloh System W14 "Superstructure W 14 with clamp Skl 14", disclosed on the internet at http://www.vossloh-railsystems.de on 12.05.2004 at 13:57:04 for concrete sleepers, which are usually on ballast beds. The gravel bed is elastic, so that no thicker elastic pads or intermediate plates are required in this construction.

Beiden Arten ist gemein: Seitlich wird die Schiene durch Kunststoff-Winkelführungsplatten in Position gehalten; je eine Schwellenschraube durchgreift diese Platte und wird in den im Beton eingegossenen Dübel aus Kunststoff eingeschraubt und fixiert so die Platte in ihrer Lage sowie die Spannklemme auf dem Schienenfuß. Durch den langen elastischen Federweg einer W-förmigen Spannklemme aus Federstahl wird die Schiene dauernd kraftschlüssig verspannt.Both types have in common: The rail is held in position by plastic angle guide plates on the side; depending on a sleeper screw passes through this plate and is screwed into the cast in concrete plastic anchor and thus fixes the plate in position and the tension clamp on the rail. Due to the long elastic travel of a W-shaped tension clamp made of spring steel, the rail is constantly clamped non-positively.

Bekannt ist auch aus der Praxis eine andere Form, z.B. der Oberbau Ks, mit Rippenplatte und einer Unterlage / Zwischenlage unter dem Schienenfuß. Die Rippenplatte wird durch je eine Schraube beidseits des Schienenfußes, die entweder in Dübeln in Spannbetonschwellen oder direkt in eine Holzschwelle geschraubt werden, gehalten.Also known from practice another form, for example, the superstructure Ks, with ribbed plate and a pad / liner under the rail. The ribbed plate is held by one screw each on both sides of the rail foot, which are screwed either in dowels in prestressed concrete sleepers or directly in a wooden sleeper.

Aus der US-A-2,337,497 ist eine starre Schienenbefestigung bekannt, bei der die auf den Schraubenbolzen sitzenden Befestigungsklemmen die Schiene mit ihrem Schienenfuß und auch die gesamte Konstruktion durch ihren Formschluss und die starre Verschraubung mittels der Muttern starr halten. Deshalb können die beiden Kunststoffplatten, zwischen denen eine metallische, starre Schlenenplatte angeordnet Ist, auch nur eine sehr begrenzte Elastizität besitzen, weil sonst die gesamte starre Konstruktion nicht funktionieren kann.From the US-A-2,337,497 is a rigid rail mounting known in which the seated on the bolts mounting clamps hold the rail with its rail foot and the entire structure by their positive connection and the rigid screw through the nuts rigid. Therefore, the two plastic plates, between which a metallic, rigid Schlenenplatte is arranged, also have only a very limited elasticity, because otherwise the entire rigid construction can not work.

Aus der DE 199 32 991 A1 ist eine schwingungsdämpfende Einzelstütze aus elastischem Kunststoff bekannt, bei welcher die Schraubenbolzen durch Aussparungen in der obersten Platte aus körnigem Füllstoff oder aus Gummischrot hindurchgeführt und in Dübel eingeschraubt sind, die in eine Schwelle eingesetzt sind. Die Schienenbefestigung umfasst mehrere elastische, übereinander angeordnete Plattenelemente, einschließlich einer höhenausgleichenden Unterlage. Die oberste Platte ist mit einer Vertiefung für den Schienenfuß versehen.From the DE 199 32 991 A1 is a vibration-damping single support made of elastic plastic, in which the bolts are passed through recesses in the top plate of granular filler or rubber and screwed in dowels, which are inserted into a threshold. The rail fastening comprises a plurality of elastic, superimposed plate elements, including a height-compensating pad. The top plate is provided with a recess for the rail foot.

Von daher liegt der Erfindung die Aufgabe zugrunde, einen einfachen aber wirksamen Stützpunkt für die Oberbauart Feste Fahrbahn, beispielsweise auch für Straßenbahnen, zu schaffen, der gegenüber dem Stand der Technik verbessert und montagefreundlicher ist.Therefore, the invention has for its object to provide a simple but effective base for the superstructure slab track, for example, for trams, which is improved over the prior art and easy to assemble.

Diese Aufgabe wird erfindungsgemäß gelöst durch die kennzeichnenden Merkmale des Patentanspruches 1. Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.This object is achieved by the characterizing features of claim 1. Further developments of the invention are described in the dependent claims.

Die Erfindung umfasst für einen hochelastischen elektrisch isolierenden Stützpunkt für Schienen eines spurgeführten Fahrzeuges beidseits neben dem Schienenfuß je eine Verankerung, umfassend eine in die Tragkonstruktion integrierte Hülse aus Kunststoff, die einen Schraubenbolzen umhüllt, dessen Gewindeende aus der Verankerung zur Schienenseite herausragt, zwischen der Tragkonstruktion und dem Schienenfuß einen Satz von mehreren aufeinander liegenden Kunststoffplatten, die breiter als der Schienenfuß samt zugehöriger federnder Befestigung sind, von denen die obere Platte als Schlenenfußauflage ausgebildet ist, mindestens eine Platte elastisch und rückstellbar für eine vordefinierte Schlenenfußeinsenkung gestaltet ist und alle Platten Durchbrüche für das Gewindeende aufweisen, auf welches eine Mutter zur federnden Verspannung des Schienenfußes aufsetzbar ist.The invention comprises for a highly elastic electrically insulating support point for rails of a track-guided vehicle on both sides next to the rail each anchorage, comprising a built-in support structure sleeve made of plastic, a bolt wrapped, whose threaded end protrudes from the anchorage to the rail side, between the support structure and the rail a set of several plastic plates lying on each other, which are wider than the rail together with associated resilient mounting, of which the upper plate is formed as a Schlenenfußauflage, at least one plate elastic and is recoverable designed for a predefined Schlenenfußeinsenkung and all plates have openings for the threaded end, on which a nut for resilient clamping of the rail foot can be placed.

Bei einem derartigen Stützpunkt kann die Verankerung in einer Unterschwellung, z. B. plattenförmigen Schwellen oder in Ortbeton - im Folgenden allgemein als Tragkonstruktion bezeichnet -angeordnet, z. B. vergossen, sein. Über den nach oben vorstehenden Gewindeteil des Schraubenbolzens kann ein Satz von Kunststoffplatten gestülpt und mit der Verankerung gekoppelt werden. Nach Auflegen der Schiene, gegebenenfalls auf eine auf der obersten Platte des Satzes von Kunststoffplatten angeordneten Zwischenlage zur Verhinderung von Reibbeschädigungen des Stützpunktes, und Aufstülpen der für sich bekannten W-Feder - und hier auch zu verwendenden Feder - auf den Schienenfuß mit rückwärtiger Abstützung auf der obersten Platte, wird eine Mutter auf das Gewindeende geschraubt und angezogen. So ist zugleich die Schiene verspannt und der Satz von Kunststoffplatten kraftschlüssig aufeinander gepresst.In such a base anchorage in a sub-swelling, z. B. plate-shaped sleepers or in-situ concrete - hereinafter generally referred to as a support structure -ranged, z. B. shed be. About the upwardly projecting threaded portion of the bolt, a set of plastic plates can be slipped and coupled with the anchorage. After placing the rail, optionally on a arranged on the top plate of the set of plastic plates intermediate layer to prevent friction damage to the base, and slipping the known W-spring - and here also to be used spring - on the rail with rear support on the top plate, a nut is screwed onto the threaded end and tightened. Thus, at the same time the rail is braced and pressed the set of plastic plates frictionally to each other.

Der große Vorteil dieser Stützpunktversion liegt darin, dass er eine höhere Elastizität aufweist als bisherige Bauformen. Die In einer mittleren Lage der Vielzahl von Platten gelegene stark elastische und rückstellbare Kunststoffplatte bewirkt eine doppelte Elastizität Bei Belastung durch überrollende Lasten, wie z. B. Fahrzeugachsen, sinkt der Schienenfuß um einen zuvor berechneten Betrag ein und presst dabei die beschriebene Platte rückstellbar zusammen. Die Spannklemme am Schienenfuß mit ihrer bekannten speziellen Federcharakteristik folgt der Einsenkung im Sinne einer Teil-Entspannung der Feder, da ihre Position an der Mutter oder dem Kopf des Schraubenbolzens beibehalten wird. Beim Stand der Technik ist ein Federweg an der rückwärtigen Schlaufe, aufliegend auf der Winkelführungsplatte, kaum feststellbar, da die stählerne Druckverteilungsplatte an dieser Stelle keine merkliche Einsenkung der Winkelführungsplatte erlaubt.The big advantage of this base version is that it has a higher elasticity than previous designs. In a middle position of the plurality of plates located highly elastic and recoverable plastic plate causes a double elasticity When loaded by rolling loads such. B. vehicle axles, the rail foot decreases by a previously calculated amount and thereby presses the plate described together recoverable. The tension clamp on the rail with its known special spring characteristic follows the depression in the sense of partial relaxation of the spring, as its position on the nut or the head of the bolt is maintained. In the prior art is a Spring travel on the rear loop, resting on the angled guide plate, hardly noticeable, since the steel pressure distribution plate at this point does not allow significant lowering of the angled guide plate.

Die Erfindung erlaubt nun aber auch eine Einsenkung dieses Teils der Schienenbefestigung bzw. der oberen Platte mit Auflager für den Schienenfuß und die Federschlaufe. Damit ergibt sich auch im Bereich der Federschlaufe, abgewandt von der Schienfußseite, eine Einsenkbewegung des Stützpunktes mit entsprechendem Federweg, hervorgerufen durch die elastische Platte. Damit wird der Stützpunkt der Schiene insgesamt elastischer.However, the invention also allows a depression of this part of the rail fastening or the upper plate with supports for the rail and the spring loop. This results in the area of the spring loop, facing away from the Schienfußseite, a Einsenkbewegung the base with a corresponding spring travel, caused by the elastic plate. Thus, the base of the rail is more elastic overall.

Da die Verankerung mit Vorsprüngen versehen ist, sitzt sie torsionssicher im Beton. Mindestens die unterste Platte, aber zur Versteifung vorzugsweise auch die oberste Platte des Satzes von Kunststoffplatten, ist mit einer Verrippung an der Unterseite ausgestattet. Die unterste Platte kann daher mit der Verrippung formschlüssig in die bei Anwendung von Ortbeton noch frische Beton-Oberfläche der Unterschwellung eingreifen und einen sicheren Sitz erhalten. Werksseitig kann also die Unterschwellung samt Verankerung und unterster Platte hergestellt sein, wenn nicht, wie später beschrieben, der Stützpunkt auf Fester Fahrbahn in situ hergestellt werden soll.Since the anchorage is provided with projections, it sits torsion-proof in the concrete. At least the bottom plate, but preferably also the top plate of the set of plastic plates for stiffening, is provided with a ribbing on the underside. The bottom plate can therefore interlock positively with the ribbing in the application of in-situ concrete fresh concrete surface of the undercut and get a secure fit. By default, therefore, the under-swelling together with anchoring and bottom plate can be made, if not, as described later, the base on solid pavement to be made in situ.

In einer Ausführung soll die oberste Platte des Satzes als Führungsplatte für den Schienenfuß und die Feder ausgebildet sein und ersetzt so eine herkömmliche Winkelführungsplatte und auch eine Rippenplattenfunktion. Außerdem kann die oberste Platte des Satzes als Führung für den Schraubenbolzen ausgestattet sein, z.B. indem dieser zur Führung für einen gewindelosen Teil des Schraubenbolzens mit einer integralen Hülse ausgestattet wird.In one embodiment, the top plate of the set is to be formed as a guide plate for the rail base and the spring and thus replaces a conventional angled guide plate and also a ribbed plate function. In addition, the top plate of the set may be provided as a guide for the bolt, e.g. by providing it with an integral sleeve for guiding a non-threaded portion of the bolt.

Die Verankerung und mindestens eine der Platten sollten form- und / oder kraftschlüssig miteinander koppelbar sein. Dazu kann nach einer Ausführungsform die Umhüllung der Verankerung zum Gewindeende hin konisch sein und die unterste Platte ebenso nach unten einen sich konisch erweiternden Durchbruch aufweisen, der komplementär zum konischen Teil der Umhüllung der Verankerung gestaltet ist. Durch diese Maßnahme können Horizontalkräfte in dieser Ebene von der Verankerung auf die Platten übertragen werden.The anchoring and at least one of the plates should be positively and / or non-positively coupled to each other. For this purpose, according to one embodiment, the sheathing of the anchorage to the threaded end can be conical and the lowermost plate is also conical downwards extending breakthrough, which is designed to be complementary to the conical part of the envelope of the anchorage. By this measure, horizontal forces in this plane can be transferred from the anchoring to the plates.

Der Zusammenbau und temporäre Halt der Teile des Stützpunktes untereinander bzw. relativ zur Schiene wird durch eine entsprechende komplementäre und steckbare Ausbildung der Teile für ein entsprechendes Fügen der Verankerung zur unteren Platte bzw. des Schraubenbolzens mit seiner temporären Führungsfunktion und Halterungseigenschaften für die Platten und Federn während des Zusammenbaues der Teile unterstützt.The assembly and temporary support of the parts of the base with each other or relative to the rail is by a corresponding complementary and plug-in design of the parts for a corresponding joining the anchorage to the lower plate or the bolt with its temporary guiding function and mounting properties for the plates and springs during assists in assembling the parts.

Die Erfindung wird nachfolgend anhand der beigefügten Zeichnungen näher beschrieben.The invention will be described in more detail with reference to the accompanying drawings.

In einer Tragkonstruktion, z. B. einer Unterschwellung oder einer Betonschwelle 9, sind zwei Verankerungen 10 eingesetzt, die integral einen Schraubenbolzen 8 mit Gewinde umhüllen. Diese Verankerung 10 hat Vorsprünge oder Verrippungen 101 zur torsionssicheren Fixierung in der Betonschwelle 9. In einer Ausführungsform kann die Umhüllung auch als Dübel mit speziellem Kopf zur Ankoppelung des Dübels oder der Umhüllung an eine untere Platte 4 gestaltet sein.In a supporting structure, for. As a sub-swelling or a concrete sleeper 9, two anchors 10 are used, which envelop a threaded bolt 8 integrally. This anchoring 10 has projections or ribs 101 for torsion-proof fixation in the concrete sleeper 9. In one embodiment, the sheath may also be designed as a plug with a special head for coupling the plug or the casing to a lower plate 4.

Auf der Unterschwellung ist eine Platte 4 aus beispielsweise Polyamid angeordnet, die an der der Betonschwelle 9 zugewandten Seiten eine Verrippung 41, 42 trägt, die sich in einer frischen Betonschwelle 9 formschlüssig einkrallen kann. An der Unterseite der Platte 4 ist der Durchbruch für die Aufnahme des Schraubenbolzens 8 konisch gestaltet und zwar komplementär zum oberen Ende der Umhüllung bzw. Verankerung 10 des Schraubenbolzens 8. Beispielsweise kann die Verankerung 10 einen Passtell 102 aufweisen, der formschlüssig und passgenau mit einer Aufnahme 43 der Platte 4 kooperiert nach Art einer Presspassung zur Übertragung von horizontalen Kräften auf die Platte 4 und den Schraubenbolzen 8. Damit wird ein Presssitz der Platte 4 auf der Umhüllung bzw. der Verankerung 10 ermöglicht.On the undercut a plate 4 is arranged, for example, polyamide, which on the concrete sleeper 9 facing sides a ribbing 41, 42 carries, which can engage in a positive concrete sleeper 9 positively. At the bottom of the plate 4 of the opening for receiving the bolt 8 is conical and that complementary to the upper end of the enclosure or anchoring 10 of the bolt 8. For example, the anchor 10 may have a Passtell 102, the form-fitting and accurately with a recording 43 of the plate 4 cooperates in the manner of an interference fit for the transmission of horizontal forces on the plate 4 and the screw bolt 8. Thus, a press fit of the plate 4 on the enclosure or the anchorage 10 is made possible.

Auf der Platte 4 sind eine elastische Platte 5 vordefinierter und für den Einsatzfall berechneter Dicke, die einfedern kann, und eine weitere hochfeste Platte 6 zur Lastübertragung und teilweisen Druckvertellung angeordnet. Zur Schiene 1 hin schließt eine mit einem eingeformten Sitz für den Schienenfuß 3 der Schiene 1 versehene oberste Platte oder Auflageplatte 7 den Stützpunkt nach oben ab. Diese Platte 7 kann integral eine Führung 12 für den Schraubenbolzen 8 aufweisen. Unter dem Fuß 3 der Schiene 1 ist noch eine für sich bekannte elastische Zwischenplatte 2 mit angeformten Rippen 21 zum sicheren Umgreifen der Auflageplatte 7 angeordnet.On the plate 4 are an elastic plate 5 predefined and calculated for the application thickness, which can rebound, and another high-strength plate 6 for load transfer and partial Druckvertellung arranged. Toward the rail 1 towards a provided with a molded seat for the rail 3 of the rail 1 top plate or support plate 7 closes the base from the top.
