Der vorliegenden Erfindung liegt das Problem zu Grunde, ein Rillenschienenherzstück bzw. ein Verfahren zur Herstellung eines solchen so weiterzubilden, dass dieses mit konstruktiv einfachen Maßnahmen zur Verfügung gestellt wird und auch über eine große Länge vom Schnittpunkt der Rillen aus betrachtet in Längsrichtung einen homogenen Werkstoffverlauf zeigt. Dabei sollen gewünschte Herzstückwinkel problemlos ausgebildet werden können. Ferner soll die Möglichkeit geschaffen sein, den verschleißintensiven Radüberlaufbereich verschleißfest auszubilden.The present invention is based on the problem, a grooved rail frog or a Process for the preparation of such a way that this with structurally simple Measures is provided and also over a long distance from the intersection of Grooved from viewed in the longitudinal direction shows a homogeneous material course. It should be desired Corner piece angle can be easily formed. Furthermore, the possibility should be be created wear-resistant form the wear-intensive Radüberlaufbereich.
Das Problem wird erfindungsgemäß mit einem Rillenschienenherzstück der eingangs genannten Art im Wesentlichen dadurch gelöst, dass die Konstruktionsprofile Vollkopfprofile mit im Herzstückschnittpunktbereich vorhandenen Köpfen sind, dass entlang der Längsachse des Herzstücks betrachtet der Verlauf eines jeden Vollkopfprofils einer Hälfte des Herzstücks entspricht, dass jeder Schienenkopf eine Schweißnahtvorbereitung mit einem Bereich aufweist, in dem die Vollkopfprofile miteinander verschweißt sind, und dass in den Schienenköpfen der Vollkopfprofile die sich schneidenden Rillen ausgebildet sind.The problem is inventively with a grooved rail frog of the type mentioned solved essentially by the fact that the construction profiles full head profiles with in the center intersection area Existing heads are considered that along the longitudinal axis of the centerpiece the course of each full-head profile of one half of the centerpiece corresponds to that of each railhead a weld preparation having a range in which the full head profiles welded together, and that in the rail heads of Vollkopfprofile itself cutting grooves are formed.
Abweichend vom vorbekannten Stand der Technik besteht der Herzstückschnittpunktbereich aus Abschnitten von zwei getrennt hergestellten Konstruktionsprofilen, die im Schnittpunktbereich wie Überlaufbereich miteinander verschweißt sind. Da das Schienenherzstück jeweils nur ein Abschnitt der miteinander verbundenen Konstruktionsprofile ist, kann im erheblichen Abstand zum Herzstück selbst eine Verbindung mit Anschlussschienen erfolgen. Somit ist im unmittelbaren Bereich des Herzstückes ein Stumpfschweiß nicht erforderlich mit der Folge, dass sich in Längsrichtung ein homogener Werkstückverlauf ergibt. Da der nach dem Stand der Technik erforderliche homogene Herzstückblock nicht notwendig ist, kann der Herzstückbereich selbst kürzer ausgebildet werden. Somit ergibt sich eine kurze kompakte Bauweise, die auch große Herzstückwinkel zulässt, ohne dass der Fahrtkomfort eines ein entsprechendes Herzstück durchfahrenden Fahrzeuges beeinträchtigt wird.Deviating from the prior art, the heart-shaped intersection region consists of Sections of two separately manufactured construction profiles, which in the intersection area like Overflow area are welded together. Since the rail frog only one section at a time The interconnected construction profiles can be substantial Distance to the core itself, a connection made with connecting rails. Thus, in the immediate area of the frog does not require a butt fusion with the consequence that results in a homogeneous workpiece course in the longitudinal direction. Because of the state The technique required homogeneous core block is not necessary, the core section even shorter. This results in a short compact Construction, which also allows large frog angle, without the ride comfort of a corresponding heart of passing vehicle is impaired.
Erfindungsgemäß werden zwei symmetrische Konstruktionsprofile wie zum Beispiel Dickstegschienen oder Vierkantprofile mit Vollkopfprofil so gebogen, dass ihre Form einem in der Längsachse geteilten Herzstück entspricht. Dabei sind die Konstruktionsprofile in ihren einander zugewandten und miteinander zu verschweißenden Fügeflächen plan bearbeitet. Die Schienenköpfe selbst weisen Schweißnahtvorbereitungen wie Fugen auf, um die Konstruktionsprofile durch Verbindungsschweißung verbinden zu können. Dabei kann die Schweißverbindung aus verschiedenen Lagen bestehen, die gegebenenfalls Zusätze aufweisen. Insbesondere kann die Verschweißung eine Decklage mit einem Zusatzwerkstoff umfassen, der sowohl für Verbindungsschweißungen zum Beispiel für hochlegierte rostfreie Stähle und Mischverbindungen zwischen diesen und normalen Baustählen als auch als Auftragswerkstoff für Schienen und Weichenteile üblich ist. Hierdurch ergibt sich die Möglichkeit, dass die verwendeten Schweißzusatzwerkstoffe verschleißmindernde Eigenschaften erfahren, so dass insbesondere die von dem Rad durchfahrenen Bereiche verschleißfest ausgebildet werden können. Hierzu ist auch vorgesehen, dass die sich kreuzenden Rillen des Herzstückes in ihren Böden bzw. ihrem gemeinsamen Boden durch Schweißmaterial gebildet sind bzw. ist.According to the invention, two symmetrical construction profiles, such as thick-web rails, are used or square profiles with full head profile bent so that their shape is one in the Longitudinal axis divided heart corresponds.

Especially the welding may comprise a cover layer with a filler material which for joint welding, for example, for high-alloyed stainless steels and Mixed connections between these and normal structural steels as well as an order material is common for rails and switch parts. This gives rise to the possibility that the used welding consumables experience wear-reducing properties, so that in particular, the areas traversed by the wheel are designed to be wear-resistant can. For this purpose, it is also provided that the intersecting grooves of the centerpiece in their Soils or their common bottom are formed by welding material or is.

Andere Verbindungsarten sind gleichfalls möglich. In addition, the construction profiles can have two or more screw connections be fixed to each other and as a unit formed on a common base plate be arranged and connected to this by normal welding techniques. Other Connection types are also possible.

Längsachse geteilten fertigen Herzstückes 10 entsprechen. In ihren vorgesehenen Fügeflächen
werden die Profile 18, 20 plan bearbeitet. Ferner erfolgt im jeweiligen Schienenkopf eine
Schweißnahtvorbereitung in Form von Fugen 22, 24, 26, 28, die für das Verschweißen der
Konstruktionsprofile 18, 20 erforderlich sind. Sodann werden die Konstruktionsprofile 18, 20
zueinander mittels Schraubverbindungen 34 kraftschlüssig verbunden. Dabei können die
Schraubverbindungen Nord-Lock-Schraubsicherungen aufweisen. Insoweit wird auf bekannte

24, 26, 28, 30, 32 ausgebildeten Schweißnähte sind mit den Bezugszeichen 38, 40, 42
versehen, wobei in den Schnittdarstellungen die Schweißnähte selbst bereits teilweise bearbeitet
sind, und zwar durch Ausbilden der Rillen 12, 14; denn erst nach dem Verschweißen
der Konstruktionsprofile 18, 20 werden in deren Köpfen 19, 21 die Rillen 12, 14 ausgebildet,
so dass infolgedessen im Schnittbereich 44 der Rillen 12, 14 die Schweißnaht 42 bis auf
einen Bodenbereich abgetragen ist, der gleichzeitig den Boden der den Radüberlaufbereich 44
schneidenden Rillen 12, 14 ist.The construction profiles 18, 20 are then in the longitudinal direction of the core 10 in

Herzstücks 10 in dessen Längsrichtung Konstruktionsprofile verschweißt, die im Ausgangszustand
ein Vollkopfprofil zeigen. Die erfindungsgemäße Lehre ermöglicht die Herstellung
von Herzstücken z. B. mit kleinen Herzstückwinkeln zwischen zum Beispiel 0° - 40°
und/oder Flachrillenbereichen gewünschte Länge, auf denen die Spurkranzkuppe eines Rades
abrollen kann.The teaching of the invention is in the immediate vicinity of the intersecting
