- the open groove portion 22 is slightly widened with respect to the widened handling portion 19 with the terminal 20 downwards.
- a locking member 12 is provided which has no widened handling portion 19 but only a locking portion 18. Accordingly, the open groove region 22 is also not expanded, but continues the groove depth and shape from the locking opening 13 into the engagement region 23.
- the locking element 12 is, as this particular from Fig. 5 results in such a manner inserted into the locking opening 13 that the wedge surface faces downwards.
- the clarifies Fig. 5 in that the thickness of the wedge-shaped locking element 12 at the narrower end is less than the groove depth of the grooves 15, 16, whereas it is slightly larger at the other end.

Abstract
Description
Die Erfindung betrifft einen Kreuzungsbereich einer Rillenschrenenkreuzung, nach dem Oberbegriff des Anspruchs 1.The invention relates to an intersection of a Rillenschrenenkreuzung, according to the preamble of
Ein Kreuzungsbereich der eingangs genannten Art ist bereits aus der
Aus der Praxis ist es bereits bekannt, an dem Ober- und dem Untergurt Laschen im Verbindungsbereich anzuschweißen, die dann mit einer Auflageoder Bodenplatte verschraubt werden. Da der Kreuzungsbereich allerdings beim Überfahren erheblichen Belastungen unterliegt, kann es bei nicht ordnungsgemäßen Anziehen der Schraubverbindungen leicht zu einem Lösen kommen.From practice, it is already known to weld on the upper and the lower flange straps in the connection region, which are then bolted to a support or bottom plate. However, since the crossing area is subject to considerable loads when driving over, it can easily come to a release in improper tightening the screw.
Aufgabe der vorliegenden Erfindung ist es daher, einen Kreuzungsbereich für eine Rillenschienenkreuzung zur Verfügung zu stellen, wobei der Ober- und der Untergurt in möglichst einfacher und kostengünstiger Weise sicher miteinander verbindbar sind.Object of the present invention is therefore to provide a crossing area for a grooved rail crossing available, the upper and the lower flange are connected in a simple and cost-effective manner safely together.
Die vorgenannte Aufgabe ist bei einem Kreuzungsbereich für eine Rillenschienenkreuzung der eingangs genannten Art erfindungsgemäß im wesentlichen dadurch gelöst, daß eine Verriegelungseinrichtung zur formschlüssigen Verriegelung des Obergurtes und des Untergurtes gegeneinander vorgesehen ist. Hierzu weist die Verriegelungseinrichtung wenigstens ein zwischen dem Obergurt und dem Untergurt wirksames Verriegelungselement zum Einsetzen in eine zwischen dem Obergurt und dem Untergurt ausgebildete oder vom Obergurt in den Untergurt übergehende Verriegelungsöffnung auf. Das Verriegelungselement ist also zum gemeinsamen formschlüssigen Eingriff sowohl in den Obergurt als auch in den Untergurt ausgebildet.The above object is achieved according to the invention at an intersection for a grooved rail crossing of the type mentioned in the main that a locking device for interlocking locking of the upper flange and the lower flange is provided against each other. For this purpose, the locking device has at least one locking element which is effective between the upper belt and the lower belt for insertion into a locking opening formed between the upper belt and the lower belt or passing from the upper belt into the lower belt. The locking element is therefore designed for common positive engagement both in the upper flange and in the lower flange.
Anders als beim Stand der Technik wird bei der Erfindung eine unmittelbare Verriegelung des Ober- und des Untergurtes gegeneinander vorgenommen. Dabei wird die Verriegelung durch Formschluß bewirkt. Eine derartige Verriegelung kann grundsätzlich an jeder Stelle des Kreuzungsbereichs vorgesehen sein, so daß die Zugänglichkeit ohne weiteres gegeben ist. Eine derartige Formschlußverbindung ist im übrigen nicht nur ausgesprochen wirksam, um eine sichere Befestigung des Ober- und des Untergurtes bzw. der Gurte aneinander zu erzielen, eine solche Verriegelung läßt sich auch relativ einfach mechanisch realisieren und ist damit kostengünstig.Unlike the prior art, an immediate locking of the upper and lower chord is made against each other in the invention. The locking is effected by positive engagement. Such a lock can be provided in principle at any point of the crossing area, so that the accessibility is given readily. Such a form-fitting connection is not only extremely effective in order to achieve a secure attachment of the upper and the lower flange or the straps together, such a lock can also be relatively easily implemented mechanically and is therefore inexpensive.
Im übrigen ist es zur Herstellung einer sicheren Befestigung des Obergurtes am Untergurt (und vice versa) ausreichend, wenn die Befestigung der beiden Gurte aneinander ausschließlich über die erfindungsgemäße Verriegelungseinrichtung erfolgt. Insbesondere sind keine weiteren Verbindungsarten wie eine Verschweißung oder eine Verschraubung der Gurte aneinander bzw, miteinander notwendig,Moreover, it is sufficient for producing a secure attachment of the upper flange on the lower flange (and vice versa) when the attachment of the two straps to each other exclusively via the locking device according to the invention. In particular, no other types of connection, such as welding or screwing of the straps to one another or to one another, are necessary.
Grundsätzlich gibt es verschiedene Möglichkeiten, die Verriegelungsöffnung auszubilden und anzuordnen. Bevorzugt wird die Verriegelungsöffnung von korrespondierenden Nuten gebildet, die im zusammengesetzten Zustand des Obergurtes und des Untergurtes die Verriegelungsöffnung bilden. Vorzugsweise ist es dabei so, daß eine erste Nut an einer Seitenflanke der ersten Ausnehmung des Obergurtes vorgesehen ist, während die dazu korrespondierende zweite Nut unterhalb der zweiten Ausnehmung des Untergurtes in dessen Seitenflanke vorgesehen ist Derartige Nuten lassen sich durch entsprechende Bearbeitung des Obergurtes und des Untergurtes sehr leicht herstellen.In principle, there are various possibilities for forming and arranging the locking opening. Preferably, the locking opening is formed by corresponding grooves which form the locking opening in the assembled state of the upper flange and the lower flange. Preferably, it is such that a first groove is provided on a side edge of the first recess of the upper flange, while the corresponding second groove is provided below the second recess of the lower flange in the side edge of such groove can be by appropriate processing of the upper flange and the lower flange very easy to make.
Um einen sicheren Formschluß und eine sichere Verriegelung zu erzielen, sollten die erste Nut und auch die zweite Nut einen rechteckförmigen Querschnitt aufweisen, so daß sich dementsprechend ein rechteckförmiger Querschnitt der Verriegelungsöffnung ergibt. Dabei versteht es sich dann, daß das Verriegelungselement eine Querschnittsform aufweist, die zumindest im wesentlichen der Querschnittsform der Verriegelungsöffnung entspricht. Außerdem sollte das Verriegelungselement eine Länge haben, die zumindest im wesentlichen der Länge der Verriegelungsöffnung entspricht.In order to achieve a secure positive engagement and a secure locking, the first groove and the second groove should have a rectangular cross-section, so that accordingly a rectangular cross-section of the locking opening results. It will then be understood that the locking element has a cross-sectional shape which corresponds at least substantially to the cross-sectional shape of the locking opening. Furthermore the locking element should have a length which corresponds at least substantially to the length of the locking opening.
Im übrigen hat es sich gezeigt, daß.die Verriegelungsöffnung über ihre gesamte Länge einen konstanten Querschnitt aufweisen sollte. Eine derartige Verriegelungsöffnung läßt sich nicht nur relativ leicht herstellen, sie bietet, wenn sie von beiden Seiten her zugänglich ist, auch den Vorteil, daß, je nach Einbaulage und bedarfsweise, das Verriegelungselement von beiden Enden her in die Verriegelungsöffnung eingeführt werden kann.Moreover, it has been shown that the locking opening should have a constant cross section over its entire length. Such a locking opening can be not only relatively easy to produce, it offers, if it is accessible from both sides, also the advantage that, depending on the installation position and, if necessary, the locking element can be inserted from both ends into the locking hole.
Insbesondere bei einer Verriegelungsöffnung mit über ihre Länge konstantem Querschnitt bietet es sich an, wenn das Verriegelungselement keilförmig ausgebildet ist Durch eine Verkeilung ergibt sich dann ein Reibschluß, durch den letztlich sichergestellt werden kann, daß sich das Verriegelungselement nicht unbeabsichtigt löst. Dabei sollte der Keil eine möglichst geringe Steigung haben, so daß eine sichere Verkeilung gewährleistet werden kann. Der Keilwinkel sollte vorzugsweise zwischen 0,1° und 5° liegen.In particular, in a locking opening with constant over its length cross-section, it makes sense if the locking element is wedge-shaped by wedging then results in a frictional engagement, can ultimately be ensured that the locking element does not accidentally dissolves. The wedge should have the smallest possible pitch, so that a secure wedging can be ensured. The wedge angle should preferably be between 0.1 ° and 5 °.
Um das Verriegelungselement in einfacher Weise in die aus den Nuten sich ergebende Verriegelungsöffnung einsetzen zu können, ist bei einer bevorzugten Ausführungsform vorgesehen, daß sich die zweite Nut als offener Nutbereich an der Seitenflanke des Untergurtes im Anschluß an den Obergurt fortsetzt. Hierdurch kann als Verriegelungselement ein starrer langgestreckter Riegel verwendet werden, der über den offenen Nutbereich der zweiten Nut in die Verriegelungsöffnung eingeschoben werden kann.In order to use the locking element in a simple manner in the resulting from the grooves locking opening is provided in a preferred embodiment, that the second groove continues as an open groove area on the side edge of the lower flange following the upper flange. In this way, as a locking element, a rigid elongate bolt can be used, which can be inserted over the open groove portion of the second groove in the locking hole.
Bevorzugt ist es im übrigen, daß sich die erste Nut über die gesamte Breite des Obergurtes erstreckt und damit von beiden Seiten her zugänglich ist. Dementsprechend sollte sich der offene Nutbereich der zweiten Nut an beiden Seiten im Anschluß an den Obergurt fortsetzen, so daß das Verriegelungselement bedarfsweise von der einen oder anderen Seite in die Verriegelungsöffnung eingesetzt werden kann.It is preferred, moreover, that the first groove extends over the entire width of the upper flange and is thus accessible from both sides. Accordingly, the open groove portion of the second groove should continue on both sides adjacent to the upper flange, so that the locking element can be used as needed from one side or the other in the locking hole.
Zur weiteren Erleichterung der Handhabung beim Einsetzen des Verriegelungselements in die Verriegelungsöffnung, aber auch zum gegebenenfalls notwendigen Lösen bzw. Entriegeln der Verriegelung ist vorgesehen, daß die zweite Nut endseitig einen vertieften und verbreiterten Eingriffsbereich aufweist. Ein solcher Eingriffsbereich erleichtert das Ansetzen und Einbringen des Verriegelungselementes in die Verriegelungsöffnung.To further facilitate handling when inserting the locking element in the locking hole, but also to possibly necessary loosening or unlocking the lock is provided that the second groove end has a recessed and widened engagement portion. Such an engagement region facilitates the attachment and insertion of the locking element in the locking opening.
Bei einer alternativen Ausführubgsform der vorliegenden Erfindung weist die Verriegelungsöffnung eine erste Bohrung im Obergurt und eine zweite Bohrung im Untergurt auf, wobei die Bohrungen ineinander übergehen bzw. miteinander ausgefluchtet sind. Um eine möglichst geringe Länge der Bohrungen zu haben, verläuft bei dieser Ausführungsform die Verriegelungsöffnung schräg zur Längsausrichtung des Obergurtes und des Untergurtes.In an alternative embodiment of the present invention, the locking opening has a first bore in the upper flange and a second bore in the lower flange, wherein the holes merge into one another or are aligned with each other. In order to have the shortest possible length of the holes, in this embodiment, the locking opening extends obliquely to the longitudinal orientation of the upper flange and the lower flange.
Wenngleich es grundsätzlich ausreichend ist, lediglich an einer Seite eine Verriegelung zwischen Ober- und Untergurt vorzusehen, sollten aus sicherheitstechnischen Gründen vorzugsweise an beiden Seitenflanken Verriegelungen vorgesehen werden. Hierbei ist es bevorzugt, daß die erste Nut an beiden Seitenflanken der ersten Ausnehmung des Obergurtes und die zweite Nut an beiden Seitenflanken des Untergurtes identisch ausgebildet sind, so daß beim Zusammenstecken der Obergurtes und des Untergurtes bzw. beim Aufsetzen des Obergurtes auf den Untergurt nicht auf die Ausrichtung des Obergurtes geachtet werden muß. Es spielt also keine Rolle, oder der Obergurt in der einen oder der anderen Richtung auf den Untergurt aufgesetzt wird.Although it is basically sufficient to provide only one side of a lock between the upper and lower belt, should be provided for safety reasons, preferably on both side flanks locks. It is preferred that the first groove on both side edges of the first recess of the upper flange and the second groove on both side flanks of the lower flange are identical, so that when mating the upper flange and the lower flange or when placing the upper flange on the lower flange not on The alignment of the upper flange must be respected. So it does not matter, or the upper belt is placed in one direction or the other on the lower belt.

Im übrigen erstreckt sich die erste Nut 15 über die gesamte Breite des Obergurtes 2 mit der Folge, daß die Verriegelungsöffnung 13 von beiden Seiten her offen ist. Dabei setzt sich der offene Nutbereich 22 der zweiten Nut 16 an beiden Seiten im Anschluß an den Obergurt 2 fort. Dabei ist, wie sich dies aus den

Bei der dritten Ausführungsform entspricht die Anordnung und Ausbildung der Nuten 15, 16 derjenigen der zweiten Ausführungsform. Allerdings weist das Verriegelungselement 12 hierbei wiederum einen Verriegelungsabschnitt 18 und einen Handhabungsabschnitt 19 mit Anschlag 20 auf. Der Anschlag 20 steht dabei nach außen hin, das heißt in Richtung auf den Obergurt 2 hin, ab. Die Keilfläche des Verriegelungselements 12 ist dabei nach außen hin, also in Richtung des Anschlags 20 gerichtet.In the third embodiment, the arrangement and configuration of the
Die vierte Ausführungsform entspricht der dritten Ausführungsform, wobei ein etwas einfacheres Verriegelungselement gewählt worden ist. Das Verriegelungselement 12 bei der vierten Ausführungsform entspricht dem bei der dritten Ausführungsform, wobei jedoch auf einen Handhabungsabschnitt 19 verzichtet worden ist. Bei dieser wie auch bei der dritten Ausführungsform ist es so, daß die auf beiden Seiten vorgesehenen Verriegelungselemente derart in die jeweilige Verriegelungsöffnung 13 eingebracht sind, daß die Keilflächen auf gegenüberliegenden Seiten bevorzugt gegenläufig angeordnet sein sollten. Bei einer nicht dargestellten Ausführungsform der vorliegenden Erfindung ist vorgesehen, daß die Verriegelungseinrichtung Bohrungsabschnitte im Obergurt und im Untergurt aufweist, nämlich eine erste im Obergurt vorgesehene, schräg verlaufende Bohrung, die in eine zweite im Untergurt vorgesehene Bohrung übergeht. Das Verriegelungselement wird dann in die schräg zur Längsrichtung des Obergurtes und auch des Untergurtes verlaufende Verriegelungsöffnung eingesetzt. Auch bei diesem Verriegelungselement kann es sich dann grundsätzlich um ein keilförmiges oder konisches, aber auch um ein zylindrisches Verriegelungselement handeln.The fourth embodiment corresponds to the third embodiment, wherein a somewhat simpler locking element has been selected.
