Description

Die Erfindung betrifft eine Gleistragplatte, welche eingerichtet ist, in einer Reihe mit solchen aufeinanderfolgend angeordneten Gleistragplatten eine Basis für die Schienen eines Gleises zu bilden, welche Gleistragplatte an ihrer Oberseite nutenartige Kanäle zur Aufnahme von geraden Schienen des Gleises sowie sich in Gleislängsrichtung erstreckende Seitenflächen und sich hierzu quer erstreckende Stirnflächen aufweist, welche eingerichtet sind, in der Reihe von Gleistragplatten den Stirnflächen von anschließenden Gleistragplatten zugewandt zu sein.The invention relates to a track plate, which is adapted to form a base for the rails of a track in a row with such successively arranged track support plates, which track plate plate on its upper side groove-like channels for receiving straight rails of the track and extending in the track longitudinal side surfaces and this has transversely extending end faces, which are arranged to be facing in the series of track-supporting plates to the end faces of subsequent track-slabs.

Deartige Gleistragplatten (vgl. z.B. DE 20 2007 001 163 U1 , EP 1 533 420 A2 , US 5,988,519 , DE 1 935 531 B1 und JP 2008-127900 ) können anstelle von Schwellen als Basis für die Schienen von Gleisen vorgesehen werden, wobei in der Regel weniger Wartungsaufwand als bei Schwellen-gestützten Gleisen erforderlich ist, weil es auch bei schweren Belastungen kaum zu einem Einsinken der Platten in deren Bettung kommt. Überdies kann die Oberseite solcher Gleistragplatten unmittelbar eine Verkehrsfläche für Straßenverkehr und/oder Fußgängerverkehr bilden. Bekannt ist es hierbei auch, für die nutenartigen Kanäle sowie darin aufgenommenen Schienen einen gleichen bogenförmigen Verlauf vorzusehen.Such track slabs (cf., eg DE 20 2007 001 163 U1 . EP 1 533 420 A2 . US 5,988,519 . DE 1 935 531 B1 and JP 2008-127900 ) may be provided instead of sleepers as the basis for the rails of tracks, which usually requires less maintenance than threshold-supported tracks, because even with heavy loads hardly comes to a sinking of the plates in their bedding. Moreover, the top of such track slabs can directly form a traffic area for traffic and / or pedestrian traffic. It is also known to provide a same arcuate course for the groove-like channels and rails received therein.

Es ist ein Ziel der vorliegenden Erfindung, eine Gleistragplatte eingangs erwähnter Art zu schaffen, welche bei verschiedenen Verlaufsformen von Gleisen zur Bildung der die Schienen tragenden Basis dieser Gleise eingesetzt werden kann.It is an object of the present invention to provide a track plate of the kind mentioned in the opening paragraph which can be used in various forms of tracks to form the rail-carrying base of these tracks.

Die erfindungsgemäß ausgebildete Gleistragplatte eingangs erwähnter Art ist dadurch gekennzeichnet, dass die Gleistragplatte, in Draufsicht gesehen, die Form eines gleichschenkeligen Trapezes hat, dessen Schenkel den Verlauf der beiden Stirnflächen definieren, und dessen zueinander parallele Seiten den Verlauf der beiden Seitenflächen definieren, dass die nutenartigen Kanäle, von der einen Stirnfläche der Gleistragplatte zu deren anderen Stirnfläche geknickt oder bogenförmigen verlaufen, wobei der jeweilige geknickt oder bogenförmig verlaufende Kanal eingerichtet ist, den Querschnitt einer geraden Schiene des Gleises aufzunehmen, und dass, in Draufsicht gesehen, die Konkavseite des Verlaufes der zur Aufnahme der Schienen vorgesehenen Kanäle der kürzeren Seitenfläche der Gleistragplatte zugewandt ist.The track plate of the invention mentioned above is characterized in that the track plate, seen in plan view, has the shape of an isosceles trapezoid whose legs define the course of the two end faces, and whose mutually parallel sides define the course of the two side surfaces that the groove-like Channels, kinked from the one face of the track plate to the other end face or arcuate, wherein the respective kinked or arcuate channel is adapted to receive the cross section of a straight rail of the track, and that, seen in plan view, the concave side of the Recording the rails provided channels facing the shorter side surface of the track plate.

Durch diese Ausbildung kann der vorstehend angeführten Zielsetzung gut entsprochen werden. Diese Gleistragplatte kann sowohl als Basis für gerade verlaufende Gleisstrecken als auch als Basis für bogenförmig verlaufende Gleisstrecken Verwendung finden, wobei mit einer einzigen Bauform solcher Gleistragplatten einem in der Praxis wichtigen Bereich von Krümmungsradien Rechnung getragen werden kann. Als Basis für gerade verlaufende Gleisstrecken kann man dabei eine Reihe, wie vorstehend angeführt ausgebildeter, Gleistragplatten bilden, wobei in dieser Reihe aufeinanderfolgende Platten zueinander um 180° bezüglich einer senkrecht zur Plattenfläche verlaufenden geometrischen Achse gewendet sind. Zur Bildung einer Basis für bogenförmig verlaufende Gleisabschnitte kann man solche Gleistragplatten in einer Reihe gleichsinnig aufeinanderfolgend anordnen, wobei der im Bogen außen verlaufende Seitenrand der Reihe durch die langen Seitenränder der einzelnen Platten gebildet ist und der innere Bogenrand der Reihe durch die kurzen Seitenränder der einzelnen Platten gebildet ist.Through this training, the above-mentioned objective can be well met. This track plate can be used both as a basis for straight track sections as well as a basis for arcuate track tracks use, with a single design of such track slabs an important in practice range of radii of curvature can be taken into account. As a basis for straight track sections can thereby form a series, as mentioned above, formed track slabs, wherein in this row successive plates are turned to each other by 180 ° with respect to a plane perpendicular to the plate surface geometric axis. To form a base for arcuately extending track sections, such track slabs can be arranged in a row in the same direction, wherein the arcuate outboard side edge of the series is formed by the long side edges of the individual plates and the inner edge of the sheet through the short side edges of the individual plates is formed.

Eine bevorzugte Ausführungsform der erfindungsgemäßen Gleistragplatte, welche für die Bemessung der Abstände zwischen dem Schienenkopf und den seitlichen Rändern der Kanäle und damit auch für die Bemessung der Spurkranzrille vorteilhaft ist, zeichnet sich dadurch aus, dass der Querschnitt der zur Aufnahme der Schienen vorgesehenen Kanäle im Bereich der Oberseite der Gleistragplatte eingeengt ist, wobei an diesen Bereich nach unten anschließend sich dieser Querschnitt durch Hinterschneidung an den Seitenflächen dieser Kanäle aufweitet. Hierbei ergibt sich eine günstige Ausführungsform, wenn die Seitenflächen der zur Aufnahme der Schienen vorgesehenen Kanäle von der im Bereich der Oberseite der Gleistragplatte vorgesehenen Einengung weg nach unten zunächst bezüglich der Mitte des jeweiligen Kanals nach außen geneigt und dann weiter zur Sohle des jeweiligen Kanals nach unten abfallend verlaufen. Eine Variante, welche eine breite Sohlenfläche für die zur Aufnahme der Schienen vorgesehenen Kanäle ergibt, ist dadurch gekennzeichnet, dass die Seitenflächen der zur Aufnahme der Schienen vorgesehenen Kanäle von der im Bereich der Oberseite der Gleistragplatte vorgesehenen Einengung weg nach unten bezüglich der Mitte des jeweiligen Kanals nach außen geneigt abfallend zur Sohle des jeweiligen Kanals verlaufen. Eine weitere günstige Ausführungsform, die auch für die Unterbringung relativ hoch ausgebildeter Schienenbefestigungsklemmen günstig ist, ist dadurch gekennzeichnet, dass die Seitenflächen der zur Aufnahme der Schienen vorgesehenen Kanäle von der im Bereich der Oberseite der Gleistragplatte vorgesehenen Einengung weg nach unten zunächst bezüglich der Mitte des jeweiligen Kanals horizontal nach außen und dann weiter zur Sohle des jeweiligen Kanals nach unten abfallend verlaufen. Eine weitere Variante hinsichtlich des Querschnittes der zur Aufnahme der Schienen vorgesehenen Kanäle ist dadurch gekennzeichnet, dass die Seitenflächen der zur Aufnahme der Schienen vorgesehenen Kanäle von der im Bereich der Oberseite der Gleistragplatte vorgesehenen Einengung weg nach unten, sich bezüglich der Mitte des jeweiligen Kanals gewölbeartig erweiternd, zur Sohle verlaufen. Diese Variante ist hinsichtlich der Belastbarkeit der Oberseite der Gleistragplatte, welche Oberseite eine Verkehrsfläche bilden kann, von Vorteil.A preferred embodiment of the track base plate according to the invention, which is advantageous for the dimensioning of the distances between the rail head and the lateral edges of the channels and thus also for the design of the flange groove, is characterized in that the cross section of the channels provided for receiving the rails in the area is narrowed to the top of the track plate, which at this area down then this cross section widens by undercut on the side surfaces of these channels. This results in a favorable embodiment, when the side surfaces of the channels provided for receiving the rails from the intended in the top of the track plate narrowing downwards initially inclined relative to the center of the respective channel outward and then on to the sole of the respective channel down sloping down. A variant which gives a broad sole surface for the channels provided for receiving the rails is characterized in that in that the side surfaces of the channels provided for receiving the rails run away from the narrowing provided in the area of the upper side of the track plate in a downward direction with respect to the center of the respective channel, sloping towards the sole of the respective channel. Another favorable embodiment, which is also favorable for the accommodation of relatively highly trained rail fastening clamps, is characterized in that the side surfaces of the channels provided for receiving the rails of the measures provided for in the region of the top of the track plate plate narrowing down first, first with respect to the center of the respective Channel horizontally outward and then continue to the bottom of the respective channel sloping down. A further variant with regard to the cross section of the channels provided for receiving the rails is characterized in that the side surfaces of the channels provided for receiving the rails extend downward from the narrowing provided in the region of the upper side of the track plate, widening like a vault with respect to the center of the respective channel , to the sole. This variant is in terms of the load capacity of the top of the track plate, which top can form a traffic area advantage.

Für die Positionierung und Lagejustierung der Gleistragplatten zueinander ist es weiter vorteilhaft, wenn man vorsieht, dass, von der Oberseite der Gleistragplatte ausgehend, an beiden Stirnflächen der Gleistragplatte jeweils eine in der Mitte zwischen den zur Aufnahme der Schienen vorgesehenen Kanälen angeordnete Markierungsnut vorgesehen ist.For the positioning and positional adjustment of the track plate to each other, it is also advantageous if it is provided that, starting from the top of the track plate, at both end faces of the track plate each one provided in the middle between the channels provided for receiving the rails channels marking groove is provided.

Für die Höhennivellierung und für die Fixierung der gegenseitigen Positionen von in einer Reihe aufeinanderfolgend angeordneten Gleistragplatten ist es vorteilhaft, wenn man vorsieht, dass an den Seitenflächen der Gleistragplatten, an die Stirnflächen anschließend, in Längsrichtung der Gleistragplatten verlaufende Nuten vorgesehen sind, und weiter in diese Nuten zur gegenseitigen Höhennivellierung und Verbindung aneinanderschließend angeordneter Gleistragplatten dienende Keile eingefügt sind.For height leveling and for fixing the mutual positions of track supports successively arranged in a row, it is advantageous to provide grooves extending in the longitudinal direction of the track plate plates on the side surfaces of the track plate plates, adjacent to the end surfaces Grooves for mutual height leveling and connection of successively arranged track plate serving wedges are inserted.

Wie erwähnt kann die Oberseite erfindungsgemäß ausgebildeter Gleistragplatten eine Verkehrsfläche bilden, wobei auch oft das Bedürfnis besteht, an solche Gleistragplatten seitlich weitere Verkehrsflächen anzuschließen, z.B. zur Bildung schienengleicher Bahnübergänge. Es ist dabei für den Anschluss des Schichtaufbaues von Verkehrsflächen, z.B. von Asphaltbetonschichten, an die Seitenflächen von Gleistragplatten hier in Rede stehender Art, von Vorteil, wenn man vorsieht, dass die Seitenflächen der Gleistragplatte, von der Oberseite der Gleistragplatte ausgehend, zunächst eine steil abfallende Zone und danach eine flacher abfallend nach außen gerichtete Zone aufweisen.As mentioned above, the top of the invention formed track slabs form a traffic surface, which is often the There is a need to connect such traffic track plates side more traffic areas, for example, the formation of railroad level crossings. It is for the connection of the layer structure of traffic areas, for example of asphalt concrete layers, on the side surfaces of track slabs here in question standing type, advantageous if it is provided that the side surfaces of the track plate, starting from the top of the track plate initially a steeply sloping Zone and then have a shallow sloping outward zone.

Für das Anbringen von Schienen an den Gleistragplatten kann man vorteilhaft an der Sohle der zur Aufnahme der Schienen vorgesehenen Kanäle Befestigungselemente zur Fixierung der Schienen vorsehen. Es können aber auch andere Maßnahmen zur Befestigung der Schienen vorgesehen werden, z.B. die Verwendung von Einguss-Massen, die die Schienen in den für ihre Aufnahme vorgesehenen Kanälen fixieren.For attaching rails to the track base plates, it is advantageous to provide fastening elements for fixing the rails to the sole of the channels provided for receiving the rails. However, other measures for fixing the rails may be provided, e.g. the use of sprues that fix the rails in the channels intended for their reception.

Die Sohle der zur Aufnahme der Schienen vorgesehenen Kanäle kann im Wesentlichen eben oder auch seitlich geneigt verlaufen, z.B. um eine Schrägstellung der Schienen zu erhalten. Eine solche Neigung kann auch nur in einem Teilbereich der Sohle, in dem die betreffende Schiene aufliegt, vorgesehen werden. Auch kann ein eingetieftes Schienenbett in einem Teilbereich der Sohle zur Lagerung der Schienen vorgesehen werden.The sole of the channels provided for receiving the rails may be substantially flat or also laterally inclined, e.g. to get an inclination of the rails. Such an inclination can also be provided only in a portion of the sole in which the relevant rail rests. Also, a recessed rail bed may be provided in a portion of the sole for supporting the rails.

Der eine Seitenrand 28' der Reihe 27' ist durch die langen Seitenflächen 5 der einzelnen Gleistragplatten 1 und der andere Seitenrand 29' der Reihe 27' durch die kurzen Seitenflächen 6 der einzelnen Gleistragplatten 1 gebildet. So wird durch die Trapezform der mit ihren Stirnflächen 2, 3 aneinanderliegenden Gleistragplatten 1 eine polygonal gekrümmt verlaufende Reihe 27' gebildet, wobei in die Kanäle 8 der diese Reihe bildenden Gleistragplatten bogenförmig gekrümmte Schienen eines bogenförmig verlaufenden Gleises eingefügt werden können. Fig. 5 shows, again in plan view, a series 27 'of inventively designed track base plates 1, wherein in this series 27', unlike the in Fig. 4 shown row 27, the track carrier plates follow each other in the same position. The one side edge 28 'of the row 27' is formed by the long side surfaces 5 of the individual track slabs 1 and the other side edge 29 'of the row 27' by the short side surfaces 6 of the individual track slabs 1. Thus, the trapezoidal shape of the adjacent with their faces 2, 3 track support plates 1 a polygonal curved row 27 'is formed, which can be inserted into the channels 8 of the train forming this series track curved rails of an arcuate track.

Die in die Kanäle 8 der Gleistragplatte einzufügenden Schienen 9 können in diesen Kanälen auf verschiedene Weise befestigt bzw. fixiert werden. Eine bevorzugte Ausführungsform sieht vor, an der Sohle der zur Aufnahme der Schienen vorgesehenen Kanäle 8 Befestigungsklemmen zur Fixierung der Schienen anzuordnen. Es sind aber auch andere Techniken anwendbar, z.B. Einguss-Massen, welche an den Wänden der Kanäle haften und an den Schienen haften und/oder die Schienen umschließen. Man kann dabei vorzugsweise elastische Einguss-Massen anwenden, z.B. Verbundmaterialien aus Korkpartikeln und einem Elastomer; man kann dabei den Massen zur Abstimmung ihrer Eigenschaften auch kornförmige steife Partikel, wie z.B. Sande, zugeben.The rails 9 to be inserted in the channels 8 of the track plate can be fastened or fixed in these channels in various ways. A preferred embodiment provides to arrange at the sole of the channels provided for receiving the rails 8 mounting clamps for fixing the rails. However, other techniques are applicable, e.g. Injection masses which adhere to the walls of the channels and adhere to the rails and / or enclose the rails. It is possible to use preferably elastic sprues, e.g. Composite materials of cork particles and an elastomer; It is also possible for the masses to match their properties with granular rigid particles, such as e.g. Sands, admit.

Stellschrauben, die an den Befestigungselementen vorliegen, zu ermöglichen ist. Entsprechende Erweiterungen der Kanäle können, in Längsrichtung der Kanäle gesehen, verhältnismäßig kurz sein.The cross-sectional shape of the channels 8 can be chosen taking into account the respective rail cross-section and the respective fastenings for the rails under various possibilities, and it is also possible to provide different cross-sectional shapes at different points in the longitudinal extent of these channels, e.g. at locations where fasteners are to be located, both space being kept clear in the channels for the placement of the fasteners and, if necessary, free access to actuators, e.g. Adjusting screws, which are present on the fasteners to allow. Corresponding extensions of the channels can, viewed in the longitudinal direction of the channels, be relatively short.

Es ist oft günstig, für die zur Aufnahme der Schienen vorgesehenen Kanäle eine Querschnittsform zu wählen, die im Bereich der Oberseite der Gleistragplatten eingeengt ist und die sich an diesen eingeengten Bereich nach unten anschließend durch Hinterschneidung an den Seitenflächen dieser Kanäle aufweitet.
