Abstract

In this points sleeper, to prevent electric conduction between rail fastening and sleeper, the rails are fastened on the sleeper indirectly via bolts (4) which penetrate the sleeper in sleeves (5) made of non-conducting material. The torsion-proof bearing of the bolt nuts (10) is achieved by the sleeves (5) being widened in a bushing-shaped manner at their end (7) facing the ballast (6), and covering with the widening the bolt nuts (10) with an intermediate space (12), into which a plastic cap (13) is pressed with its cuff (14) which with its inner surface (15) surrounds positively the hexagon of the bolt nuts (10) and at the same time with its cutting ribs (17) arranged on the cuff outer surface (16) engages in a torsion-proof manner in the concrete. <IMAGE>

Description

Weichenschwelle aus SpannbetonTurnout sleeper made of prestressed concrete

Die Erfindung betrifft eine Weichenschwelle aus Spannbeton der im Oberbegriff des Anspruchs 1 beschriebenen Gattung.The invention relates to a turnout sleeper made of prestressed concrete The generic term of claim 1 described.

Für den Stand der Technik wird ausgegangen von der DE-PS 30 27 087.1. Bei dieser Schwellenkonstruktion ist die Mutter, die den Bolzen im Beton verankert, formschlüssig direkt im Beton eingegossen. Zwischen Beton und Schwelle ist damit eine leitende Verbindung vorhanden, die bei elektrifiziertem Fahrbetrieb nachteilig ist. Zu einem weiteren Nachteil kann sich die unmittelbare Einbettung der Bolzenmutter in den Beton auswirken, wenn aus Reparaturgründen die Bolzenverankerung ausgewechselt und die Mutter nach unten herausgeschlagen werden muß.The prior art is based on DE-PS 30 27 087.1. In this sleeper construction, the nut that anchors the bolt in the concrete is form-fitting cast directly into the concrete. There is thus between the concrete and the threshold a conductive connection is available, which is disadvantageous in electrified driving is. The direct embedding of the bolt nut can result in a further disadvantage affect the concrete if the bolt anchorage is replaced for repair reasons and the nut has to be knocked out downwards.

Zum einen kann beim Herausschlagen infolge der festen Haftung der Mutter im Beton der Beton in diesem Bereich beschädigt oder sogar zerstört werden, zum anderen besteht die Gefahr, daß wegen der üblichen Maßtoleranzen bei den Abmessungen der Muttern die Ersatzmutter nicht in die Hohlform der ausgeschlagenen Mutter paßt.On the one hand, when knocking out due to the firm adhesion of the Nut in the concrete the concrete in this area will be damaged or even destroyed, on the other hand, there is a risk that because of the usual dimensional tolerances in the dimensions of the nuts, the replacement nut does not fit into the hollow shape of the knocked out nut.

Um für die vorbeschriebenen Nachteile Abhilfe u schaffen, wäre es naheliegend, die Hülse aus nichtleitendem Material, z.B. aus Kunststoff, formschlüssig über die Sechskantfläche der Mutter hinwegzuführen. Eine solche Hülsenausführung wäre jedoch herstellungstechnisch schwierig und aufwendig. Der erforderliche druckverteilende Ring müßte innerhalb des Fertigungsprozesses eingebaut werden.To remedy the disadvantages u described above, it would be Obviously, the sleeve made of non-conductive material, e.g. plastic, form-fit lead away over the hexagonal surface of the nut. Such a sleeve design however, it would be difficult and expensive to manufacture. The required pressure distributing Ring would have to be installed within the manufacturing process.

Aufgabe der Erfindung ist eine wirtschaftliche Verankerungslösung der Schiene auf den Schwellen, bei der keine elektrische Leitung zwischen Schienenbefestigung und Beton besteht und Bolzen und Muttern unter Beibehaltung einer verdrehungssicheren Lagerung der Bolzenmutter in der Schwelle zerstörungsfrei von unten her auswechselbar sind.The object of the invention is an economical anchoring solution the rail on the sleepers with no electrical line between the rail fastening and concrete is made and bolts and nuts while maintaining a twist-proof Bearing of the bolt nut in the sleeper can be exchanged from below without being destroyed are.

Die Aufgabe wird durch eine Schwellenkonstruktion gelöst, wie sie im kennzeichnenden Teil des Anspruchs 1 beschrieben ist. Bei dieser Lösung umfassen Hülse und Kappe die Bolzenverankerung im Beton vollständig, so daß keine Leitungsbrücken entstehen können. Die Hülse ist mit einfachen technischen Mitteln herstellbar. Teile, die herausstoßbar sein sollen, haben mit Ausnahme der Kunststoffkappe keinen direkten Verbund mit dem Schwellenbeton. Die Kunststoffkappe kann aufgrund ihres Werkstoffs im Falle eines Austauschs sich den vorgegebenen Beton formen anpassen und Maßtoleranzen ausgleichen. Zugleich bewirkt die Kunststoffkap,e, indem sie einerseits die Bolzenmutter formschlüssig umfaßt, andererseits mit Scherrippen in den Beton einbindet, die verdrehungssichere Lagerung der Mutter in der Schwelle.The task is solved by a sleeper construction like her is described in the characterizing part of claim 1. Include in this solution Sleeve and cap completely anchor the bolt in the concrete, so that no cable bridges can arise. The sleeve can be produced with simple technical means. Parts, which should be able to be pushed out, with the exception of the plastic cap, do not have a direct one Composite with the threshold concrete. The plastic cap can be due to their material in the event of an exchange adapt to the given concrete shape and compensate for dimensional tolerances. At the same time, the plastic cap causes e by on the one hand the bolt nut encloses positively, on the other hand with shear ribs in the concrete integrates the torsion-proof mounting of the nut in the threshold.

Eine zweckmäßige Ausgestaltung der Kappe, besonders zur Hilfe für den Einbau der Verankerungskonstruktion in die Schalung bei der Schwellenherstellung, beschreibt Anspruch 2.A useful design of the cap, especially to help the installation of the anchoring structure in the formwork during sleeper manufacture, describes claim 2.

Die Erfindung wird durch ein Ausführungsbeispiel in den Figuren 1 und 2 erläutert.The invention is illustrated by an exemplary embodiment in FIGS and 2 explained.

Fig. 1 zeigt einen Schnitt durch die Schwelle mit der erfindungsgemäßen Schienenbefestigung, Fig. 2 zeigt das Detail der Schienenbefestigung im Bereich der muffenförmigen Erweiterung der Hülse.Fig. 1 shows a section through the threshold with the inventive Rail fastening, Fig. 2 shows the detail of the rail fastening in the area the sleeve-shaped extension of the sleeve.

Auf der Schwelle 1 werden die Schienen 2 mittelbar über Rippenplatten 3 mit Schraubbolzen 4 in der Schwelle befestigt. Die Hülse 5 weist in ihrem der Bettung 6 zugekehrten Ende eine muffenförmige Erweiterung 7 auç? die die Bolzen- mutter 10 zu einem wesentlichen Teil umfaßt.On the sleeper 1, the rails 2 are indirectly via ribbed plates 3 fastened with screw bolts 4 in the threshold. The sleeve 5 has in its the Bedding 6 facing the end a sleeve-shaped extension 7 auç? which the bolt mother 10 includes a substantial part.

Der Boden 8 der muffenförmigen Erweiterung ist zur Bolzenachse senkrecht und eben ausgebildet und dient zur Auflage eines Druckrings 9, der den Anpreßdruck der Bolzenmutter 10 auf den umgebenden Beton der Schwelle 1 weiterleitet.The bottom 8 of the sleeve-shaped extension is perpendicular to the bolt axis and designed flat and serves to support a pressure ring 9, the contact pressure the bolt nut 10 passes on to the surrounding concrete of the sleeper 1.

In den Zwischenraum 12 zwischen Muffenmanschatte 11 und Mutter 10 ist die Manschette 14 einer Kunststoffkappe 13 eingedrückt. Die Manschette 14 umfaßt mit der Innenfläche 15 formschlüssig den Sechskant der Mutter 10 und ist auf ihrer Außenfläche 16 im in den Beton der Schwelle 1 eingebetteten Bereich mit Scherrippen 17 versehen, die eine Verdrehung der Kappe 13 im Beton der Schwelle verhindern. Die Deckplatte 18 der Kappe 13 weist eine Öffnung 19 auf, deren Durchmesser größer als der Durchmesser des Bolzens 4 ist. Die Öffnung 19 ist mit einem Deckel 20 verschlossen.Into the space 12 between the socket shell 11 and the nut 10 the sleeve 14 of a plastic cap 13 is pressed in. The cuff 14 includes with the inner surface 15 positively the hexagon of the nut 10 and is on her Outer surface 16 in the area embedded in the concrete of the sleeper 1 with shear ribs 17 provided, which prevent rotation of the cap 13 in the concrete of the sleeper. The cover plate 18 of the cap 13 has an opening 19, the diameter of which is larger than the diameter of the bolt 4. The opening 19 is closed with a cover 20.
