Herzstücke ergeben sich bei Weichen oder Kreuzungen durch Überschneidungen von Schienensträngen, wobei im Herzstück die Fahrtkanten der sich kreuzenden Schienenstränge unterbrochen sind. Die sich von den Zungenschienen her fortsetzenden Schienenstränge werden im Herzstückbereich abgeknickt und als Flügelschienen bezeichnet.At the turnouts or intersections, intersections of rail tracks give rise to intersections, whereby the edges of the intersecting rail tracks are interrupted in the center.

Um mögliche Materialänderungen aufgrund des Schweißens zu vermeiden, wird das Herzstück, also nachdem die Flügelschiene über die Futterstücke mit dem Herzstückblock verschweißt worden ist, als Einheit vergütet.In order to avoid possible material changes due to welding, the core, ie after the wing rail has been welded to the core block via the lining pieces, is tempered as a unit.
Der
Bei einem Herzstück nach der
In der Praxis hat sich durchgesetzt, dass die Futterstücke mit der Herzstückspitze und den Flügelschienen hochfest verschraubt werden, da man davon ausgeht, dass eine diesbezügliche Konstruktion kostengünstig ist und zudem einen geringen Montageaufwand erfordert. Es hat sich jedoch gezeigt, dass sich entsprechende Schraubverbindungen lösen können.In practice, it has been established that the lining pieces are bolted to the frog point and the wing rails with high strength, since it is assumed that a construction in this respect is inexpensive and also requires little installation effort. However, it has been shown that corresponding screw connections can be solved.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Gleisabschnitt sowie ein Verfahren zum Verbinden von Gleisbauteilen der eingangs genannten Art so weiterzubilden, dass bei einfacher Konstruktion eine auch hohen Belastungen standhaltende sichere Verbindung gegeben ist, durch die ein bleibender Abstand zwischen den Gleisbauteilen gewährleistet ist.The present invention has the object, a track section and a method for connecting track components of the type mentioned in such a way that with a simple construction, a high loads a sturdy secure connection is given, is ensured by a permanent distance between the track components.
Die Aufgabe wird erfindungsgemäß im Wesentlichen durch einen Gleisabschnitt zuvor beschriebener Art dadurch gelöst, dass von dem Schienensteg des ersten Gleisbauteils ein rohrartiges Element ausgeht, das mit dem Distanzstück stoffschlüssig verbunden ist.The object is achieved according to the invention substantially by a track section previously described type in that from the rail web of the first track component emanates a tubular element, which is materially connected to the spacer.
Erfindungsgemäß wird eine stoffschlüssige Verbindung genutzt, um das Distanzstück mit dem bzw. den Gleisbauteilen zu verbinden, wobei jedoch dem Grunde nach der Gefügezustand der Gleisbauteile unbeeinflusst bleibt, da die stoffschlüssige Verbindung ausschließlich zwischen dem rohrförmigen Element und dem Distanzstück verlaufen sollte, das nach dem Stand der Technik auch geschweißt wird. Dabei kann im Falle eines Herzstückes die Anzahl der erfindungsgemäßen Verbindungen der Anzahl üblicher Schraubverbindungen entsprechen.According to the invention a cohesive connection is used to connect the spacer with the track or the components, but the reason of the structural state of the track components remains unaffected, since the cohesive connection should extend exclusively between the tubular member and the spacer, according to the state The technology is also welded. In the case of a centerpiece, the number of connections according to the invention may correspond to the number of conventional screw connections.
Durch das indirekte Schweißen, also das nicht direkte Schweißen zwischen Distanzstück und Schiene, können beliebige Schienengüten eingesetzt werden, ein besonderer Vorteil der erfindungsgemäßen Lehre.By indirect welding, so not direct welding between spacer and rail, any rail qualities can be used, a particular advantage of the teaching of the invention.
Es wird in Bezug auf die Schiene quasi ein indirektes Schweißen angewendet, da die Schiene nicht unmittelbar oder im Wesentlichen nicht unmittelbar geschweißt werden. Als Schweißverfahren kommen in Frage insbesondere Schutzgasschweißen, vorzugsweise Metall-Aktivgasschweißen, vorzugsweise MAG 135/136 nach DIN EN ISO 4063:2011-03, oder Lichtbogenschweißen, insbesondere Lichtbogenhandschweißen 111 nach DIN EN ISO 4063:2011-03.There is virtually indirect welding applied to the rail because the rail is not welded directly or substantially directly. Suitable welding methods are in particular inert gas welding, preferably metal-active gas welding, preferably MAG 135/136 according to DIN EN ISO 4063: 2011-03, or arc welding, in particular manual metal arc welding 111 according to DIN EN ISO 4063: 2011-03.
Insbesondere ist vorgesehen, dass das rohrförmige Element, wie Buchse, eine Durchgangsöffnung, wie Bohrung, in dem Schienensteg durchsetzt, so dass von der distanzstückabgewandten Seite des Stegs ausgehend die stoffschlüssige Verbindung, wie Schweißung, durchgeführt werden kann.In particular, it is provided that the tubular element, such as bushing, passes through a passage opening, such as bore, in the rail web, so that, starting from the side of the web remote from the web, the material connection, such as welding, can be carried out.

In Weiterbildung der Erfindung ist vorgesehen, dass distanzstückseitig verlaufende Stirnfläche der Buchse zurückversetzt zur von der distanzelementseitig verlaufenden Stegaußenfläche verläuft. Mit anderen Worten bildet sich ein Spalt zwischen der Buchse und dem Distanzstück, wenn dieses an dem Steg abgestützt ist bzw. gegen diesen sich drückt. Hierdurch können Eigenspannungen in der Verbindung, die durch das Einbringen der Schweißwärme entstehen, zu einer kraftschlüssigen Verbindung der Bauteile beitragen.In a further development of the invention, it is provided that the end face of the bush extending on the distance piece side is set back in relation to the web outer surface extending from the spacer element side. In other words, a gap forms between the bush and the spacer when it is supported on the web or presses against it. As a result, residual stresses in the connection, which arise through the introduction of the welding heat, contribute to a frictional connection of the components.
Insbesondere sollte das rohrförmige Element mit dem Gleisbauteil durch Presspassung verbunden sein.In particular, the tubular element should be connected to the track component by press fitting.
