- a resilient rail fastening is known for example from DE 196 08 823 A.
- Such rail fasteners are used on solid surfaces, such as concrete, asphalt, but can also be mounted on sleepers.
- the rails lie on a threshold and are held down with laterally adjacent clamping brackets on the rail foot.
- When embedding the rail in concrete has the disadvantage that the clamping force of the resilient rail fastening is impaired.
- US Pat. Nos. 1,854,497 and 1,817,569 describe resilient rail fasteners in which a spring is pressed onto the rail foot by means of a holding device. The spring is inserted in each case in a recess of the holding device.
- the invention is therefore an object of the invention to provide a rail fastening of the type mentioned, in which it is ensured that the clamping force of the rail fastening is maintained.
- the invention provides in an advantageous manner that the clamping bracket of the rail fastening at least one chamber for receiving at least one compression spring which has.
- the inclusion of the compression spring in a chamber allows the compression spring can always act with the same clamping force on the rail. Buried soil material or an embedding of the rail in concrete can not affect the spring travel of the compression spring, so that it is ensured that always the same, predetermined clamping force acts on the rail foot.
- the chamber allows a most extensive protection of the compression spring against corrosion. This also contributes to a long-term maintenance of the original resilience of the spring.
- the chamber also protects the compression spring from overloading.
- the clamping holder has a resting on the base plate or the threshold flange portion through which the at least one sleeper screw is passed, and a housing part which receives the at least one chamber with the compression spring.
- the clamping bracket thus consists essentially of a flange, through which the sleeper screw is passed and a housing part in which the pressure acting on the rail foot spring is received.
- the chamber which receives the compression spring down, i. towards the rail foot, open. Upwards, the chamber is closed, so that no compression material or concrete can penetrate into the compression spring.
- the downwardly open chamber is arranged above the rail foot, so that the compression spring rests completely on the rail.
- the chamber has a predetermined depth, so that the bias of the compression spring is limited to a predeterminable value. This also ensures that always an equally high bias is applied by all clamps. But it can also be held with different chamber depth or compression springs of different lengths clamped to provide specifically different biasing forces. Furthermore, clamp brackets with different flange geometries for adjusting the track width of the rails be kept ready. This is done for example by different flange widths between the hole for the sleeper screw and the housing part.
- the chamber has a cylindrical shape.
- this cylindrical chamber can be used as a compression spring spring washer.
- the clamp can also have multiple chambers, each with its own compression spring or a single chamber with multiple compression springs.
- the flange part rests on the side facing away from the rail on a parallel to the rail extending outer edge of the base plate.
- the flange part can thus be supported on the base plate and allows exact positioning of the rail relative to the base plate.
- the standing with the rail foot in contact bottom surface of the housing part is adapted to the inclination of the rail foot.
- the clamping holders for the sleeper screws have slots which extend at an angle ⁇ to the rail foot or to the rail.
- the clamping bracket and the base plate have matched stop means, wherein the stop means also abut each other at the angle ⁇ of the slots of the clamping brackets. That way, one concern is the Clamping bracket against a stop guaranteed even when the clamp brackets are moved relative to the clamping screws and the base plate to change the tracking of the rail.
- the abutment means of the clamping bracket is the outer edge running on the rail side, which runs obliquely at the angle ⁇ and rests against an obliquely extending web projecting from the base plate.
- the fastening hole in the flange part of the clamping holder consists of a slot which extends in an angle parallel to the rail foot plane at an angle ⁇ to the rail obliquely.
- the abutment means of the clamping brackets and the base plate can also run parallel to the rail.
- Fig. 1 shows a cross section through a rail including the rail fastening.
- rail 1 is a tram profile.
- the rail fastening is used for releasably connecting the rail 1 to the ground.
- the rail can rest against the ground on a fixed plate or on sleepers 2.
- Fig. 1 shows a rail 1, which rests on a running in the transverse direction rail base plate 3. Between the base plate 3 and the rail 4 of the rail 1 can still be a damping plate 18, for example made of plastic, can be arranged. This damping plate 18 serves to receive the rail 1 resiliently on the base plate 3. In addition, with different thickness damping plates 18, the height position of the rail 1 can be adjusted.
- the rail 1 is covered in its lower part with a concrete layer 22.
- a bituminous bonding layer 24 is disposed and the uppermost layer 26 is made of mastic asphalt.
- the clamp holder 6 consists of a resting on the base plate 3 flange 14 and a compression spring 8 receiving housing part 16, which are preferably integrally connected to each other.
- a compression spring 8 receiving housing part 16 which are preferably integrally connected to each other.
- two sleeper screws 10 are arranged, which are screwed through a bore of the flange 14 and the base plate 3 in a threshold 2 or in a solid substrate made of concrete or a mineral mixture.
- the sleeper screws 10 In the case of wooden sleepers, the sleeper screws 10 have a wood thread. In the case of concrete sleepers, the sleeper screws 10 are dented.
- the housing part 16 extends laterally from the flange part 14 in the direction of the rail 1 and is designed such that it overlaps the rail foot 4.
- the housing part 16 has in the embodiment of FIG. 2, two downwardly open chambers 12, in each of which a compression spring 8 is arranged in the form of a spring ring.
- the spring ring can be used with play in the chamber 12, wherein the height of the chamber 12 of the height of the compression spring 8 is adapted such that the existing of a spring ring compression spring 8 is pressed against the rail 4 with a certain bias.
- the housing part 16 forms at the same time a stop, so that it is ensured that no excessive pressure forces are exerted and that the contact pressure at all clamp brackets 6 is the same.
- the housing part 16 also prevents by sealing against the rail 1 that dirt or particles can penetrate into the spring elements of the compression spring 8. In this way, the corrosion of the compression spring 8 is reduced and thus extends their life. In any case, prevents concrete mass penetrates into the compression spring 8 and thus limits their mobility. It is therefore ensured that the clamping force of the compression spring 8 is maintained even with a casting of the rail foot 4 with concrete 22, since the housing part 16, the compression spring 8 completely absorbs and seals the compression spring to the environment.
- the chamber 12 is completely above the rail foot 4, so that the compression spring 8 can be supported with its entire base on the rail 4.

Description
Die Erfindung betrifft eine Schienenbefestigung für eine Schiene mit einer Grundplatte und seitlich am Schienenfuß anliegenden Klemmhalterungen für den Schienenfuß, wobei jede Klemmhalterung mindestens eine auf den Schienenfuß einwirkende Druckfeder aufweist.The invention relates to a rail mounting for a rail with a base plate and laterally applied to the rail foot clamp brackets for the rail, each clamp has at least one force acting on the rail foot pressure spring.
Eine federnde Schienenbefestigung ist beispielsweise aus der DE 196 08 823 A bekannt. Derartige Schienenbefestigungen dienen zum Einsatz auf festen Untergründen, wie Beton, Asphalt, können aber auch auf Schwellen montiert werden.A resilient rail fastening is known for example from DE 196 08 823 A. Such rail fasteners are used on solid surfaces, such as concrete, asphalt, but can also be mounted on sleepers.
Die Schienen liegen auf einer Schwelle auf und werden mit seitlich anliegenden Klemmhalterungen am Schienenfuß niedergehalten. Bei Einbettung der Schiene in Beton besteht der Nachteil, dass die Spannkraft der federnden Schienenbefestigung beeinträchtigt wird.The rails lie on a threshold and are held down with laterally adjacent clamping brackets on the rail foot. When embedding the rail in concrete has the disadvantage that the clamping force of the resilient rail fastening is impaired.
Die US-Patentschriften US 1,854,497 und US 1,817,569 beschreiben eine federnde Schienenbefestigungen, bei der eine Feder mit Hilfe einer Haltevorrichtung auf den Schienenfuß gedrückt wird. Die Feder ist jeweils in einer Vertiefung der Haltevorrichtung eingesetzt.US Pat. Nos. 1,854,497 and 1,817,569 describe resilient rail fasteners in which a spring is pressed onto the rail foot by means of a holding device. The spring is inserted in each case in a recess of the holding device.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Schienenbefestigung der eingangs genannten Art zu schaffen, bei der sichergestellt ist, dass die Spannkraft der Schienenbefestigung erhalten bleibt.The invention is therefore an object of the invention to provide a rail fastening of the type mentioned, in which it is ensured that the clamping force of the rail fastening is maintained.
Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1.To solve this problem serve the features of
Die Erfindung sieht in vorteilhafter Weise vor, dass die Klemmhalterung der Schienenbefestigung mindestens eine Kammer zur Aufnahme mindestens einer Druckfeder der aufweist. Die Aufnahme der Druckfeder in einer Kammer ermöglicht es, dass die Druckfeder stets mit der gleichen Spannkraft auf den Schienenfuß einwirken kann. Aufgeschüttetes Bodenmaterial oder eine Einbettung der Schiene in Beton kann den Federweg der Druckfeder nicht beeinträchtigen, so dass sichergestellt ist, dass stets die gleiche, vorgegebene Spannkraft auf den Schienenfuß einwirkt. Desweiteren ermöglicht die Kammer einen weitestgehenden Schutz der Druckfeder gegen Korrosion. Auch dies trägt zu einer langjährigen Aufrechterhaltung der ursprünglichen Spannkraft der Feder bei. Die Kammer schützt die Druckfeder auch vor Überbelastung.The invention provides in an advantageous manner that the clamping bracket of the rail fastening at least one chamber for receiving at least one compression spring which has. The inclusion of the compression spring in a chamber allows the compression spring can always act with the same clamping force on the rail. Buried soil material or an embedding of the rail in concrete can not affect the spring travel of the compression spring, so that it is ensured that always the same, predetermined clamping force acts on the rail foot. Furthermore, the chamber allows a most extensive protection of the compression spring against corrosion. This also contributes to a long-term maintenance of the original resilience of the spring. The chamber also protects the compression spring from overloading.
Vorzugsweise ist vorgesehen, dass die Klemmhalterung ein auf der Grundplatte oder der Schwelle aufliegendes Flanschteil, durch das die mindestens eine Schwellenschraube hindurchgeführt ist, und ein Gehäuseteil aufweist, das die mindestens eine Kammer mit der Druckfeder aufnimmt.Preferably, it is provided that the clamping holder has a resting on the base plate or the threshold flange portion through which the at least one sleeper screw is passed, and a housing part which receives the at least one chamber with the compression spring.
Die Klemmhalterung besteht also im wesentlichen aus einem Flanschteil, durch das die Schwellenschraube hindurchgeführt ist und einem Gehäuseteil, in dem die auf den Schienenfuß einwirkende Druckfeder aufgenommen ist. Dabei ist die Kammer, die die Druckfeder aufnimmt, nach unten, d.h. in Richtung auf den Schienenfuß, offen. Nach oben ist die Kammer geschlossen, so dass kein Verdichtungsmaterial oder Beton in die Druckfeder eindringen kann.The clamping bracket thus consists essentially of a flange, through which the sleeper screw is passed and a housing part in which the pressure acting on the rail foot spring is received. In this case, the chamber which receives the compression spring, down, i. towards the rail foot, open. Upwards, the chamber is closed, so that no compression material or concrete can penetrate into the compression spring.
Bei einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass die nach unten offene Kammer oberhalb des Schienenfußes angeordnet ist, so dass die Druckfeder vollständig auf dem Schienenfuß aufliegt.In a preferred embodiment of the invention it is provided that the downwardly open chamber is arranged above the rail foot, so that the compression spring rests completely on the rail.
Die Kammer hat eine vorbestimmte Tiefe, so dass die Vorspannung der Druckfeder auf einen vorbestimmbaren Wert begrenzt ist. Dadurch ist auch sichergestellt, dass von allen Klemmhalterungen stets eine gleich hohe Vorspannung aufgebracht wird. Es können aber auch Klemmhalterungen mit unterschiedlicher Kammertiefe oder Druckfedern unterschiedlicher Länge bereitgehalten werden, um gezielt unterschiedliche Vorspannkräfte vorzusehen. Desweiteren können Klemmhalterungen mit unterschiedlichen Flanschgeometrien zur Einstellung der Spurweite der Schienen bereitgehalten werden. Dies erfolgt beispielsweise durch unterschiedliche Flanschbreiten zwischen der Bohrung für die Schwellenschraube und dem Gehäuseteil.The chamber has a predetermined depth, so that the bias of the compression spring is limited to a predeterminable value. This also ensures that always an equally high bias is applied by all clamps. But it can also be held with different chamber depth or compression springs of different lengths clamped to provide specifically different biasing forces. Furthermore, clamp brackets with different flange geometries for adjusting the track width of the rails be kept ready. This is done for example by different flange widths between the hole for the sleeper screw and the housing part.
Bei einem bevorzugten Ausführungsbeispiel ist vorgesehen, dass die Kammer eine zylindrische Form aufweist.In a preferred embodiment it is provided that the chamber has a cylindrical shape.
In diese zylindrische Kammer kann als Druckfeder ein Federring eingesetzt werden.In this cylindrical chamber can be used as a compression spring spring washer.
Die Klemmhalterung kann auch mehrere Kammern mit jeweils einer eigenen Druckfeder oder eine einzige Kammer mit mehreren Druckfedern aufweisen.The clamp can also have multiple chambers, each with its own compression spring or a single chamber with multiple compression springs.
Vorzugsweise ist vorgesehen, dass das Flanschteil auf der der Schiene abgewandten Seite an einer parallel zur Schiene verlaufenden Außenkante der Grundplatte anliegt. Das Flanschteil kann sich somit an der Grundplatte abstützen und ermöglicht eine exakte Positionierung der Schiene relativ zu der Grundplatte.It is preferably provided that the flange part rests on the side facing away from the rail on a parallel to the rail extending outer edge of the base plate. The flange part can thus be supported on the base plate and allows exact positioning of the rail relative to the base plate.
Die mit dem Schienenfuß in Kontakt stehende Bodenfläche des Gehäuseteils ist an die Neigung des Schienenfußes angepasst.The standing with the rail foot in contact bottom surface of the housing part is adapted to the inclination of the rail foot.
Nach einem weiteren Ausführungsbeispiel ist vorgesehen, dass die Klemmhalterungen für die Schwellenschrauben Langlöcher aufweisen, die unter einem Winkel α zum Schienenfuß bzw. zur Schiene verlaufen. Dadurch, dass die Langlöcher schräg verlaufen, kann die relative Position der Schiene zu der Grundplatte um einen vom Winkel α und der Länge der Langlöcher abhängigen Betrag verschoben werden. Dadurch ist es möglich, die Spurweite der Schienen um einen bestimmten Betrag zu verändern. Beispielsweise ist eine Veränderung der Spurweite an jeder Schienenbefestigung um ± 5 mm möglich, so dass die Spurweite um insgesamt ± 1 cm verändert werden kann. Dies ist vorteilhaft, um Fertigungstoleranzen auszugleichen oder um beispielsweise gezielt im Kurvenbereichen die Spurweite anders einzustellen.According to a further embodiment, it is provided that the clamping holders for the sleeper screws have slots which extend at an angle α to the rail foot or to the rail. The fact that the slots are oblique, the relative position of the rail can be moved to the base plate by an angle α and the length of the slots dependent amount. This makes it possible to change the track width of the rails by a certain amount. For example, it is possible to change the track width of each rail fastening by ± 5 mm, so that the gauge can be changed by a total of ± 1 cm. This is advantageous in order to compensate for manufacturing tolerances or to set the track width differently, for example, specifically in the curve areas.
Die Klemmhalterung und die Grundplatte weisen einander angepasste Anschlagmittel auf, wobei die Anschlagmittel ebenfalls unter den Winkel α der Langlöcher der Klemmhalterungen aneinander anliegen. Auf diese Weise ist ein Anliegen der Klemmhalterung gegen einen Anschlag auch dann gewährleistet, wenn die Klemmhalterungen relativ zu den Klemmschrauben und der Grundplatte verschoben werden, um die Spurlage der Schiene zu verändern.The clamping bracket and the base plate have matched stop means, wherein the stop means also abut each other at the angle α of the slots of the clamping brackets. That way, one concern is the Clamping bracket against a stop guaranteed even when the clamp brackets are moved relative to the clamping screws and the base plate to change the tracking of the rail.
Bei einem bevorzugten Ausführungsbeispiel ist vorgesehen, dass das Anschlagmittel der Klemmhalterung die auf der Schiene gegenüberliegenden Seite verlaufende Außenkante ist, die unter dem Winkel α schräg verläuft und gegen einen von der Grundplatte abstehenden, schräg verlaufenden Steg anliegt.In a preferred embodiment, it is provided that the abutment means of the clamping bracket is the outer edge running on the rail side, which runs obliquely at the angle α and rests against an obliquely extending web projecting from the base plate.
Nach einem weiteren Ausführungsbeispiel ist vorgesehen, dass das Befestigungsloch in dem Flanschteil der Klemmhalterung aus einem Langloch besteht, das in einer parallel zum Schienenfuß verlaufenden Ebene unter einem Winkel α zur Schiene schräg verläuft.According to a further embodiment, it is provided that the fastening hole in the flange part of the clamping holder consists of a slot which extends in an angle parallel to the rail foot plane at an angle α to the rail obliquely.
Dadurch ist es möglich, die Grundplatte gemeinsam mit den Klemmhalterungen relativ zu den Schwellenschrauben und der Schwelle zu verschieben, um die Spurlage der Schiene bzw. des Schienenstrangs zu verändern.This makes it possible to move the base plate together with the clamp brackets relative to the sleeper screws and the threshold to change the track position of the rail or of the rail track.
In diesem Fall können die Anschlagmittel der Klemmhalterungen und der Grundplatte auch parallel zur Schiene verlaufen.In this case, the abutment means of the clamping brackets and the base plate can also run parallel to the rail.
Es versteht sich allerdings, dass die Schienenbefestigung auch ohne Anschlagmittel einsetzbar ist.It goes without saying, however, that the rail fastening can also be used without slings.
Im folgenden werden unter Bezugnahme auf die Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert:In the following, embodiments of the invention will be explained in more detail with reference to the drawings:

Fig. 1 zeigt einen Querschnitt durch eine Schiene einschließlich der Schienenbefestigung. Bei der dargestellten Schiene 1 handelt es sich um ein Straßenbahnprofil. Die Schienenbefestigung dient zum lösbaren Verbinden der Schiene 1 mit dem Untergrund. Dabei kann die Schiene gegenüber dem Untergrund auf einer festen Platte oder auch auf Schwellen 2 aufliegen.Fig. 1 shows a cross section through a rail including the rail fastening. In the illustrated
Fig. 1 zeigt eine Schiene 1, die auf einer in Schienenquerrichtung verlaufenden Grundplatte 3 aufliegt. Zwischen Grundplatte 3 und dem Schienenfuß 4 der Schiene 1 kann noch eine Dämpfungsplatte 18, beispielsweise aus Kunststoff, angeordnet sein. Diese Dämpfungsplatte 18 dient dazu, die Schiene 1 federnd auf der Grundplatte 3 aufzunehmen. Außerdem kann mit unterschiedlich dicken Dämpfungsplatten 18 die Höhenposition der Schiene 1 eingestellt werden.Fig. 1 shows a
Die Schiene 1 ist in ihrem unteren Teil mit einer Betonschicht 22 abgedeckt. Auf der Betonschicht 22 ist eine bituminöse Bindeschicht 24 angeordnet und die oberste Schicht 26 besteht aus Gussasphalt.The
Die Klemmhalterung 6 besteht aus einem auf der Grundplatte 3 aufliegenden Flanschteil 14 und einem eine Druckfeder 8 aufnehmenden Gehäuseteil 16, die vorzugsweise einstückig miteinander verbunden sind. In dem Flanschteil 14 sind, wie am besten aus Fig. 2 ersichtlich ist, zwei Schwellenschrauben 10 angeordnet, die durch eine Bohrung des Flanschteils 14 und der Grundplatte 3 in eine Schwelle 2 oder in einen festen Untergrund aus Beton oder einem Mineralgemisch hineingeschraubt sind. Im Fall von Bahnschwellen aus Holz weisen die Schwellenschrauben 10 ein Holzgewinde auf. Im Fall von Betonschwellen werden die Schwellenschrauben 10 eingedübelt.The
Das Gehäuseteil 16 erstreckt sich seitlich von dem Flanschteil 14 in Richtung auf die Schiene 1 und ist so gestaltet, dass es den Schienenfuß 4 übergreift. Das Gehäuseteil 16 weist bei dem Ausführungsbeispiel der Fig. 2 zwei nach unten offene Kammern 12 auf, in denen jeweils eine Druckfeder 8 in Form eines Federrings angeordnet ist. Der Federring kann mit Spiel in die Kammer 12 eingesetzt werden, wobei die Höhe der Kammer 12 der Höhe der Druckfeder 8 derart angepasst ist, dass die aus einem Federring bestehende Druckfeder 8 mit einer bestimmten Vorspannung gegen den Schienenfuß 4 angepresst wird. Das Gehäuseteil 16 bildet dabei zugleich einen Anschlag, so dass sichergestellt ist, dass keine zu hohen Druckkräfte ausgeübt werden und dass der Anpressdruck bei allen Klemmhalterungen 6 gleich ist. Das Gehäuseteil 16 verhindert zudem durch Abdichtung gegenüber der Schiene 1, dass Schmutz oder Partikel in die Federelemente der Druckfeder 8 eindringen können. Auf diese Weise wird auch die Korrosion der Druckfeder 8 reduziert und damit deren Lebensdauer verlängert. In jedem Fall wird verhindert, dass Betonmasse in die Druckfeder 8 eindringt und damit deren Beweglichkeit einschränkt. Es ist daher gewährleistet, dass die Spannkraft der Druckfeder 8 auch bei einem Vergießen des Schienenfußes 4 mit Beton 22 erhalten bleibt, da das Gehäuseteil 16 die Druckfeder 8 vollständig aufnimmt und die Druckfeder zur Umgebung hin abdichtet.The
Bei dem dargestellten Ausführungsbeispiel ist die Kammer 12 vollständig oberhalb des Schienenfußes 4, so dass sich die Druckfeder 8 mit ihrer gesamten Grundfläche auf dem Schienenfuß 4 abstützen kann.In the illustrated embodiment, the
Die Grundplatte 3 hat an ihren parallel zur Schiene 1 verlaufenden Längskanten jeweils eine nach oben abstehende Außenkante 20, an der das Flanschteil 14 seitlich abgestützt anliegt.The
Abweichend von dem Ausführungsbeispiel können in einer Kammer 12 auch mehrere Druckfedern 8 nebeneinander oder koaxial angeordnet sein.Notwithstanding the embodiment, a plurality of compression springs 8 may be arranged side by side or coaxially in a

Die Fign. 3 und 4 zeigen ein zweites Ausführungsbeispiel der Schienenbefestigung, bei der die Grundplatte 3 ein Befestigungsloch 11 zur Aufnahme der Schwellenschraube 10 aufweist, das dem Durchmesser der Schwellenschraube angepasst ist.The Fign. 3 and 4 show a second embodiment of the rail fastening, in which the
Dagegen ist das Befestigungsloch der Klemmhalterungen 6 ein Langloch 9, das unter einem Winkel von 10 bis 25°, vorzugsweise 15°, zur Schiene einverläuft. Unter dem gleichen Winkel α verläuft auch die hintere Außenkante 15 der Klemmhalterung 6, die gegen einen von der Grundplatte 3 nach oben abstehenden Steg 21 anliegt, der ebenfalls unter dem Winkel α schräg zur Schiene 1 verläuft. Der Winkel α liegt dabei in einer horizontalen Ebene.In contrast, the mounting hole of the clamping
Mit Hilfe des schräg verlaufenden Langlochs 9, der schräg verlaufenden hinteren Außenkante 15 und dem schräg verlaufenden Steg 21 ist es möglich, beide Halterungen 6 beiderseits der Schiene 1 derart komplementär zu verschieben, dass die Mittellage der Schiene 1, quer zu ihrer Längsrichtung und parallel zur Schwelle 2 zu verschieben. Damit es möglich, die Spurweite zwischen zwei Schienensträngen einzustellen.With the help of the
Nach einem weiteren Ausführungsbeispiel gemäß Fign. 5 und 6 kann auch vorgesehen sein, dass das Befestigungsloch der Grundplatte 3 ebenfalls ein Langloch 11 ist, das unter dem gleichen Winkel α schräg zur Schiene 1 verläuft. In die diesem Fall kann die Grundplatte 3 gemeinsam mit den zwei auf ihr befindlichen Klemmhalterungen 6 in Richtung der Längsachsen der Langlöcher 9,11 verschoben werden, um die Spurlage der Schiene 1 relativ zur Schwelle bzw. relativ zu dem zweiten Schienenstrang zu verändern. In diesem Fall kann die der Schiene 1 abgewandte Außenkante 15 der Klemmhalterung 6 und der die Anschlagfläche bildende Steg 21 parallel zur Schiene 1 verlaufen. Wie den Fign. 5 und 6 entnehmbar, kann der Anschlag für die Klemmhalterung auch durch einen parallel zur Schiene verlaufenden Schlitz 19 gebildet sein, in den ein von dem Flanschteil 14 der Klemmhalterung 6 ein nach unten abstehender Vorsprung 21 eingreift.According to a further embodiment according to FIGS. 5 and 6 can also be provided that the mounting hole of the
