Abstract
Description
Die Erfindung betrifft ein Spannschloß zum Verbinden von Zugankern nach dem
Oberbegriff des Anspruchs 1. Bei einem schotterlosen Oberbau für Schienen, auf
denen Schienenfahrzeuge fahren, mit aneinanderliegenden Fahrbahnplatten, ist es
üblich, die Fahrbahnplatten mittels Zuganker gegeneinander zu verspannen. Die
Zuganker erstrecken sich üblicherweise durch die aneinanderliegenden Fahrbahnplatten.The invention relates to a turnbuckle for connecting tie rods according to the
Preamble of
Wenigstens die Enden der Zuganker weisen ein Außengewinde auf. Spannschlösser verbinden die Enden der aneinanderschließenden Zuganker.At least the ends of the tie rods have an external thread. Turnbuckles connect the ends of the connecting tie rods.
Die EP 0 516 612 A1 zeigt einen gattungsgemäßen schotterlosen Oberbau. Die aus Beton hergestellten Fahrbahnplatten und ihre Durchbrüche zur Aufnahme der Zuganker weisen Toleranzen auf. Darüber hinaus können die Fahrbahnplatten nicht immer gerade und in einer Ebene nebeneinander liegen, da Kurven und Überhöhungen des Schienenweges vorzusehen sind. Das hat zur Folge, daß bei den bisher eingesetzten Spannschlössern die ebenen Schraubenauflagen für die Spannmuttern nachteilig bewirken, daß die Zuganker an der Einspannstelle mit Biegekräften beaufschlagt werden, was im Extremfall sogar zu einer plastischen Verformung der Enden der Zuganker führt. EP 0 516 612 A1 shows a generic ballastless superstructure. From Concrete roadway slabs and their breakthroughs to accommodate the Tie rods have tolerances. In addition, the pavement slabs cannot always straight and next to each other in a plane, because of curves and cant of the rail track are to be provided. As a result, the previously used turnbuckles the flat screw supports for the clamping nuts disadvantageously cause the tie rods to be subjected to bending forces at the clamping point become, which in extreme cases even leads to a plastic deformation of the ends the tie rod leads.
Der Erfindung liegt die Aufgabe zugrunde, ein Spannschloß zum Verbinden von Zugankern
nach dem Oberbegriff des Anspruchs 1 derartig weiterzubilden, daß es am
Ende der Zuganker nicht mehr zu Zwängungen oder Verbiegungen kommt.The invention has for its object a turnbuckle for connecting tie rods
according to the preamble of
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.
Eine vorteilhafte Aus- und Weiterbildung wird in Anspruch 2 beschrieben.This object is achieved by the features of
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß beliebige Einbaulagen der Fahrbahnplatten und auch große Fertigungstoleranzen sich nicht mehr auf die Anbindung der Zuganker auswirken. Es kann sichergestellt werden, daß die Zuganker nur noch mit reinen Zugkräften belastet werden, wodurch diese eine höhere Lebensdauer erhalten. Weiterhin vorteilhaft wird erreicht, daß der Zuganker nach dem Spannen nicht mehr seitlich durch den Schlitz aus dem Spannschloß herausrutschen kann.The advantages achieved by the invention are in particular that any Installation positions of the carriageway slabs and also large manufacturing tolerances are not affect the connection of the tie rods more. It can be ensured that the tie rods are only loaded with pure tensile forces, making this one get longer life. It is also advantageously achieved that the tie rod after tensioning no longer laterally through the slot from the turnbuckle can slip out.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen

Wie aus den Fig. 1 bis 3 erkennbar ist, ist das Spannschloß 1 kettengliedartig ausgebildet.
Dabei weist es im Mittenbereich einen dünnen Querschnitt auf. An den Enden
2, an denen die Zuganker 3 befestigt sind, ist ein größerer Querschnitt vorgesehen.
In diesem Bereich sind Auflageflächen 4 für die Muttern 5 im Innenbereich angeordnet.
Die Zuganker 3 sind zumindest an ihren Enden 6 mit einem Außengewinde ausgebildet,
die mit den Muttern 5 zusammenwirken, so daß über die Muttern 5 ein

kongruent ausgebildeten, sphärisch konkaven Anlagefläche 9. Auf der ebenen Gegenfläche
10 der Scheibe 8 liegt die Mutter 5 auf. Schiefstellungen der Muttern 5 aufgrund
nicht fluchtender Zuganker 3 oder sonstiger Fertigungs- und Maßtoleranzen

Scheibe 8 auf der sphärisch konvexen Auflagefläche 4 am Spannschloß 1 in einfacher
Weise ausgeglichen werden. 4 and 5 that the
