Description

Die Erfindung betrifft eine Stoßstelle zwischen zwei aus Beton bestehenden Längsschwellen eines Gleisrostes nach dem Oberbegriff des Anspruchs 1.The invention relates to a joint between two longitudinal sleepers made of concrete of a track grate according to the preamble of claim 1.

Eine derartige Stoßstelle ist aus der DE 297 00 893 U1 bekannt. Dort wiesen die aus Beton bestehenden Längsschwellen an ihren Stirnseiten vertikale Aussparungen auf, in die ein in die jeweilige Längsschwelle einbetoniertes Halteelement ragt. Die Halteelemente zweier benachbarter Längsschwellen werden durch Verbindungselemente miteinander verbunden. Nach dem Ausrichten der Längsschwellen werden die Aussparungen mit fließfähigem Beton ausgefüllt, so dass sich nach dem Aushärten des Betons ein stabiler Verbund zwischen benachbarten Längsschwellen ergibt. Obwohl eine derartige Stoßstelle einen dauerhaften und sicheren Verbund ermöglicht, können im Vergussbeton besonders an den glatten Stirnflächen der Längsschwellen Risse (z.B. Schwindrisse) entstehen.Such a joint is from the DE 297 00 893 U1 known. There, the existing longitudinal concrete sleepers on their front sides on vertical recesses, in which a projecting into the respective longitudinal threshold holding element projects. The holding elements of two adjacent longitudinal sleepers are connected to one another by connecting elements. After aligning the longitudinal sleepers, the recesses are filled with flowable concrete, so that after hardening of the concrete results in a stable bond between adjacent longitudinal sleepers. Although such a joint allows a durable and secure bond, cracks (eg shrinkage cracks) can occur in the grouting concrete, especially on the smooth end faces of the longitudinal sleepers.

Aufgabe der Erfindung ist es, eine Stoßstelle der eingangs genannten Art zu schaffen, die einen verbesserten und möglichst rissfreien Verbund zwischen den Längsschwellen ermöglicht.The object of the invention is to provide a joint of the type mentioned, which allows an improved and possible crack-free composite between the longitudinal sleepers.

Diese Aufgabe wird durch eine Stoßstelle mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Weiterbildungen und vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a joint with the features of claim 1. Advantageous developments and advantageous embodiments of the invention are the subject of the dependent claims.

Bei der erfindungsgemäßen Stoßstelle sind die einander zugewandeten Stirnflächen der Längsschwellen durch eine Zahnung profiliert. Zusammen mit einem Vergussbeton wirkt die Zahnung bei der Querkraftübertragung wie eine Verbindung aus Nut und Feder und begrenzt die Länge von Rissen (z.B. Schwindrisse), die im Vergussbeton entstehen können.In the joint according to the invention, the mutually facing end faces of the longitudinal sleepers are profiled by a toothing. Along with a grouting concrete, the toothing acts as a tongue and groove joint in shear force transmission and limits the length of cracks (e.g., shrinkage cracks) that can occur in the grout.

In einer besonders vorteilhaften Ausführung ist die Zahnung durch horizontale oder vertikale Nuten gebildet. Die Zahnung kann aber auch durch vertikale und horizontale Nuten gebildet sein. Anstelle der Nuten kann auch durch entsprechende Vorsprünge an den Stirnflächen eine Zahnung erreicht werden. Die Nuten haben vorzugsweise einen trapezförmigen Querschnitt, können jedoch auch andere Querschnitte aufweisen.In a particularly advantageous embodiment, the toothing is formed by horizontal or vertical grooves. The toothing can also be formed by vertical and horizontal grooves. Instead of the grooves can also by corresponding projections on the end faces a Toothing can be achieved. The grooves preferably have a trapezoidal cross section, but may also have other cross sections.

In einer einfach herstellbaren und kostengünstigen Ausführung können die Halteelemente stabförmige einbetonierte Dübel aus Stahl und die Verbindungselemente Zulageeisen sein, die an den Dübeln anliegen und mit diesen fest verbunden, vorzugsweise verschweißt sind.In a simple to produce and cost-effective design, the holding elements can be rod-shaped cast-in anchors made of steel and the fasteners Zulageeisen, which abut the dowels and fixedly connected to these, preferably welded.

Die Halteelemente können aber auch aus einbetonierten U-förmigen Schlaufen bestehen, die durch mindestens einen Bügel und dazugehörige Quereisen als Verbindungselemente miteinander verbunden sind.But the holding elements can also consist of cast-in U-shaped loops, which are connected by at least one bracket and associated trailing arms as connecting elements.

Die Länge der einzelnen Längsschwellen beträgt beispielsweise 6m, wobei mit den Längsschwellen ein starrer Schwellenstrang von beispielsweise 30 m hergestellt werden kann. Parallel zueinander verlaufende Längsschwellen können an ihren Enden und dazwischen in entsprechenden Abständen über Querstege miteinander verbunden sein.The length of the individual longitudinal sleepers is, for example, 6 m, with the longitudinal sleepers a rigid threshold strand of, for example, 30 m can be produced.
