Date Jun. 9, 1994A support system for a rail section which bridges the gap between foundations which are relatively movable auxiliary rails running parallel to the rail across the sleepers which are supported by the foundation, and underpinning supports providing a stiff connection between rail and auxiliary rails. The underpinning supports move in response to relative movement of the foundation so that undesirable rail bending is avoided.

Description

Die Erfindung bezieht sich auf eine Unterstützung für eine Schiene zwischen relativ zueinander verschiebbaren, die Schiene festlegenden Unterlagen wie Schwellen, insbesondere für einen Schienenabschnitt eines Dehnungsstoßes im Bereich einer Brückenfuge.The invention relates to a support for a rail between documents which can be displaced relative to one another and which fix the rail, such as sleepers, in particular for a rail section of an expansion joint in the region of a bridge joint.

Um im Oberbau z.B. im Bereich von Brücken eine Relativbewegung zwischen Bauwerk und Gleis zu ermöglichen, werden Dehnungsstöße, die auch als Schienenauszug bezeichnet werden, benutzt. Dehnungsstöße umfassen Zunge und Backenschiene, die relativ zueinander verschiebbar sind. Hierzu kann eine Zunge zwischen der Backenschiene und einer auf der gegenüberliegenden Seite ortsfest angeordneten Klemmbacke festgelegt werden.In order to e.g. In the area of bridges to allow a relative movement between the structure and the track, expansion joints, which are also referred to as a rail extension, are used. Expansion joints include the tongue and stock rail, which are displaceable relative to one another. For this purpose, a tongue can be fixed between the stock rail and a clamping jaw arranged on the opposite side.

Im Bereich der Fuge fehlt häufig eine Unterstützung der Schiene, so daß dann, wenn die Fuge relativ breit ist, beim Durchfahren der Schiene eine unerwünschte Durchbiegung dieser erfolgt.In the area of the joint, there is often no support for the rail, so that when the joint is relatively wide, undesired deflection occurs when the rail is driven through.

Der Erfindung liegt die Aufgabe zugrunde, eine Unterstützung für eine Schiene zwischen relativ zueinander verschiebbaren, die Schienen festlegenden Unterlagen wie Schwellen, insbesondere für einen Schienenabschnitt eines Dehnungsstoßes im Bereich einer Brückenfuge derart weiterzubilden, daß unerwünschte Durchbiegungen der Schiene unterbleiben, so daß sich gleisähnliche Verhältnisse im Bereich zwischen den relativ zueinander verschiebbaren Unterlagen einstellen. Ferner soll unabhängig von der Größe des Abstandes zwischen den zueinander verschiebbaren Unterlagen mit konstruktiv einfachen Mitteln eine Vergleichmäßigung der Abstützung erfolgen.The invention has for its object to provide support for a rail between relatively displaceable, the rail-defining documents such as sleepers, in particular for a rail section of an expansion joint in the region of a bridge joint such that undesirable deflections of the rail are avoided, so that track-like conditions in the Set the area between the documents that can be moved relative to each other. Furthermore should Irrespective of the size of the distance between the mutually displaceable documents, the support can be made more uniform with structurally simple means.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß parallel zu beiden Seiten der Schiene Stützelemente verlaufen, die von den Unterlagen ausgehen und zwischen denen zumindest eine die Schiene abstützende Abstützung verläuft, die in Längsrichtung sowohl der Stützelemente als auch der Schiene verschiebbar ausgebildet ist.The object is achieved in that support elements run parallel to both sides of the rail, which emanate from the documents and between which runs at least one support supporting the rail, which is designed to be displaceable in the longitudinal direction of both the support elements and the rail.

Erfindungsgemäß wird die Schiene im Bereich zwischen den relativ zueinander verschiebbaren Unterlagen wie Schwellen, insbesondere im Bereich einer Brückenfuge durch Abstützungen, die vorzugsweise plattenförmig ausgebildet sind, unterfangen und derart abgestützt, daß beim Durchfahren der Schiene ein unerwünschtes Durchbiegen unterbleibt. Hierzu gehen die Abstützungen von Stützelementen vorzugsweise in Form von Stützschienen, die auch als Hilfsschienen bezeichnet werden können, aus, die ihrerseits auf den Unterlagen wie Schwellen festgelegt sind, auf denen die Schiene selbst abgestützt ist.According to the invention, the rail is underpinned and supported in the area between the mutually displaceable supports such as sleepers, in particular in the area of a bridge joint, by supports, which are preferably plate-shaped, such that undesired bending does not occur when the rail is passed through. For this purpose, the supports of support elements are preferably in the form of support rails, which can also be referred to as auxiliary rails, which in turn are defined on the documents such as sleepers on which the rail itself is supported.

Es erfolgt quasi eine Versteifung der Schiene im Bereich der Brückenfuge dadurch, daß der Schienenfuß sich auf zumindest einer Abstützplatte abstützt, die ihrerseits von den zu beiden Seiten der Schiene und in deren Längsrichtung verlaufende Stützschienen ausgeht.There is a kind of stiffening of the rail in the area of the bridge joint in that the rail foot is supported on at least one support plate, which in turn starts from the support rails running on both sides of the rail and in its longitudinal direction.

Vorzugsweise sind zumindest zwei plattenförmige Abstützungen vorhanden, die sowohl relativ zu der Schiene und zu den Stützschienen als auch zueinander verschiebbar ausgebildet sind. Dabei erfolgt ein Verschieben entlang der Stützschienen und der Schiene derart, daß eine Vergleichmäßigung der Abstützung der Schiene im Bereich der Brückenfuge erfolgt. Hierzu gehen von den Hilfsschienen bzw. der Schiene einerseits und von der bzw. den Abstützungen andererseits Mitnehmer bzw. Begrenzer vorzugsweise in Form von Nocken aus, durch die die Abstützungen beim Verschieben der Stützschienen bzw. der Schiene in Abhängigkeit von ihrer Stellung mitgenommen oder festgehalten werden.At least two plate-shaped supports are preferably provided, which are designed to be displaceable both relative to the rail and to the support rails and to one another. A shift along the support rails and the rail takes place in such a way that the support of the rail is evened out in the region of the bridge joint. For this purpose, the auxiliary rails or the rail on the one hand and the support or supports on the other hand entrainers or limiters, preferably in the form of cams, through which the Supports when moving the support rails or the rail depending on their position are carried or held.

In weiterer Ausgestaltung der Erfindung sind die Stützelemente wie Stützschienen ortsfest mit einer der relativ zueinander verschiebbaren Unterlagen wie Schwellen verbunden, so daß bei einer Relativbewegung zwischen Bauwerk und Gleis ein Verschieben zu der anderen Unterlage erfolgen kann. Demgegenüber ist die Schiene mit der Unterlage, mit der die Stützschiene nicht ortsfest verbunden ist, fester verbunden als mit der anderen Unterlage.In a further embodiment of the invention, the support elements, such as support rails, are connected in a stationary manner to one of the supports, such as sleepers, which can be displaced relative to one another, so that a movement to the other support can take place when there is a relative movement between the structure and the track. In contrast, the rail is more firmly connected to the base with which the support rail is not connected in a fixed manner than to the other base.

In den Fig. 1 bis 3, in denen gleiche Elemente mit gleichen Bezugszeichen versehen sind, sind Ausschnitte eines Gleises im Bereich von Brückenfugen (10), (12) und (14) dargestellt, die unterschiedliche Breiten aufweisen.1 to 3, in which the same elements are provided with the same reference numerals, sections of a track in the region of bridge joints (10), (12) and (14) are shown which have different widths.

Der Gleisabschnitt umfaßt Schienen (16), (18), die auf Schwellen (20), (22), (24) und (26) abgestützt sind.The track section comprises rails (16), (18) which are supported on sleepers (20), (22), (24) and (26).

Die Schwellen (20) und (22) sind relativ zu den Schwellen (24) und (26) verschiebbar, die z.B. auf einem Bauwerk wie einer Brücke befestigt sind. Die Schienen (16) und (18) münden in einem an und für sich bekannten Dehnungsstoß, der im Ausführungsbeispiel rechts liegen kann. Dieser Dehnungsstoß besteht aus einer Backenschiene und einer Zunge, die relativ zueinander verschiebbar sind.The thresholds (20) and (22) are displaceable relative to the thresholds (24) and (26), which e.g. are attached to a structure like a bridge. The rails (16) and (18) open into an expansion joint which is known per se and which can be on the right in the exemplary embodiment. This expansion joint consists of a stock rail and a tongue that can be moved relative to each other.

Um die Schienen (16) und (18) im Bereich der Brückenfuge (10) bzw. (12) bzw. (14) zu unterstützen, wird erfindungsgemäß folgende Konstruktion vorgeschlagen.In order to support the rails (16) and (18) in the area of the bridge joint (10) or (12) or (14), the following construction is proposed according to the invention.

Parallel zu den Schienen (16) und (18) verlaufen Hilfs- oder Stützschienen (28), (30) bzw. (32) und (34), die gleichfalls von den Schwellen (20) und (22) bzw. (24) und (26) ausgehen. Dabei sind die Stützschienen (28), (30), (32) und (34) ortsfest mit den Schwellen (24) und (26) über sogenannte Wanderschütze verbunden, von denen zwei beispielhaft mit den Bezugszeichen (36) und (38) versehen sind. Auf den anderen, relativ zu den Schwellen (24) und (26) verschiebbaren Schwellen (20) und (22) sind die Stützschienen (28) und (30) über Gleitklemmplatten verbunden, um wiederum eine Relativbewegung zu den Schwellen (20) und (22) zu ermöglichen, Zwei Gleitklemmplatten weisen rein beispielhaft die Bezugszeichen (40) und (42) auf.Auxiliary or support rails (28), (30) or (32) and (34) run parallel to the rails (16) and (18) and also from the sleepers (20) and (22) or (24). and (26) going out. The support rails (28), (30), (32) and (34) are fixedly connected to the sleepers (24) and (26) by means of so-called hiking contactors, two of which are provided with the reference numerals (36) and (38) by way of example are. On the other sleepers (20) and (22) which can be displaced relative to the sleepers (24) and (26), the support rails (28) and (30) are connected via slide clamping plates in order to in turn cause a relative movement to the sleepers (20) and ( 22), two slide clamping plates have the reference numerals (40) and (42) purely by way of example.

Die Schienen (16) und (18) sind ihrerseits auf den Schweilen (20) und (22) über übliche Spannklemmen (44) und (46) festgelegt, die nur eine geringe Relativbewegung zwischen der Schiene (16) bzw. (18) und den Schwellen (20) und (22) zulassen. Demgegenüber sind die Schienen (16) und (18) mit den Schwellen (24) und (26) weniger fest verbunden, und zwar über Klemmen (48) und (50), die eine Relativbewegung zwischen den Schienen (16) und (18) und den Schwellen (24) und (26) zulassen.The rails (16) and (18) are in turn fixed on the welds (20) and (22) via conventional tensioning clamps (44) and (46), which have only a slight relative movement between the rails (16) and (18) and allow thresholds (20) and (22). In contrast, the rails (16) and (18) are less firmly connected to the sleepers (24) and (26), namely via clamps (48) and (50), which allow a relative movement between the rails (16) and (18). and allow thresholds (24) and (26).

Von den Stützschienen (28) und (30) bzw. (32) und (34) ausgehend und senkrecht zu ihren Längsrichtungen verlaufend erstrecken sich plattenförmige Abstützungen (52), (54) und (56), (58), die die Schienen (16) und (18) unterseitig unterfassen und diese gleichzeitig abstützen. Hierzu erfolgt eine Verbindung zwischen den Abstützungen (52), (54), (56) und (58) und den Schienen (16) und (18) über Spannklemmen, von denen wiederum rein beispielhaft zwei mit den Bezugszeichen (60) und (62) versehen sind.Starting from the support rails (28) and (30) or (32) and (34) and extending perpendicular to their longitudinal directions, plate-shaped supports (52), (54) and (56), (58) extend the rails ( 16) and (18) underside and support them at the same time. For this purpose, a connection is made between the supports (52), (54), (56) and (58) and the rails (16) and (18) via tension clamps, two of which are again given by way of example with the reference numerals (60) and (62 ) are provided.

Um nicht nur eine Relativverschiebung entlang der Schienen (16) und (18), sondern auch entlang der Stützschienen (28), (30), (32) und (34) zu ermöglichen, erfolgt eine Verbindung über Gleitklemmplatten (63), (65), die den Gleitklemmplatten (40) und (42) entsprechen.To enable not only a relative displacement along the rails (16) and (18), but also along the support rails (28), (30), (32) and (34), a connection is made via slide clamping plates (63), (65 ), which correspond to the slide clamping plates (40) and (42).

Durch die zuvor beschriebenen Verbindungen zwischen den Abstützungen (52), (54), (56) und (58) und den Schienen (16) und (18) sowie den Stützschienen (28), (30), (32) und (34) ist sichergestellt, daß die Schienen (16) und (18) im Bereich der Brückenfuge (10) bzw. (12) bzw. (14) im erforderlichen Umfang unterstützt werden, so daß ein unerwünschtes oder unzulässiges Durchbiegen beim Durchfahren eines Fahrzeuges vermieden wird.Through the previously described connections between the supports (52), (54), (56) and (58) and the rails (16) and (18) and the support rails (28), (30), (32) and (34 ) it is ensured that the rails (16) and (18) in the area of the bridge joint (10) or (12) or (14) are supported to the extent necessary so that undesired or inadmissible deflection when driving through a vehicle is avoided .

Um unabhängig von der Breite der Brückenfuge (10), (12) bzw. (14) eine gleichmäßige Abstützung der Schienen (16) und (18) zu ermöglichen, sind die Abstützungen (52), (54), (56) und (58) erwähntermaßen sowohl relativ zu den Schienen (16) und (18) als auch zu den Stützschienen (28), (30) und (32), (34) verschiebbar. Dabei erfolgt eine gezielte Verschiebung der Abstützungen (52), (54), (56) und (58) in Abhängigkeit von der Breite der Brückenfuge (10), (12) bzw. (14) derart, daß eine Vergleichmäßigung der Abstützung erfolgt. Um diese sicherzustellen. sind nach den Fig. 1 bis 3 Mitnehmer und Begrenzer vorgesehen, die sowohl von den Abstützungen (52), (54), (56) und (58) als auch von den Schienen (16) und (18) und den Stützschienen (28), (30), (32) und (34) ausgehen.In order to enable uniform support of the rails (16) and (18) regardless of the width of the bridge joint (10), (12) or (14), the supports (52), (54), (56) and ( 58), as mentioned, can be moved relative to the rails (16) and (18) as well as to the support rails (28), (30) and (32), (34). The supports (52), (54), (56) and (58) are shifted in a targeted manner as a function of the width of the bridge joint (10), (12) and (14) in such a way that the support is evened out. To ensure this. 1 to 3 drivers and limiters are provided, which of the supports (52), (54), (56) and (58) as well as of the rails (16) and (18) and the support rails (28th ), (30), (32) and (34).

Anhand der Abstützungen (52) und (54) sowie der Schienen (16), (28) und (30) soll die Zuordnung der vorzugsweise als Nocken ausgebildeten Mitnehmer und Begrenzer und die hierdurch bedingte Verschiebung der Abstützungen (52) und (54) entlang der Schiene (16) bzw. Hilfsschiene (28) und (30) verdeutlicht werden.Using the supports (52) and (54) and the rails (16), (28) and (30), the assignment of the drivers and limiters, which are preferably designed as cams, and the displacement of the supports (52) and (54) caused thereby the rail (16) or auxiliary rail (28) and (30) are illustrated.

So gehen von einer Seite der Schiene (16) Nocken (64) und (66) und von der gegenüberliegenden Seite ein Nocken (68) aus. Von der Abstützung (52) geht ein Nocken (71) aus, der zwischen den Nocken (64) und (66) der Schiene (16) verläuft. Ein von der Abstützung (54) ausgehender Nocken (70) ist dem Nocken (68) zugeordnet.Cams (64) and (66) emanate from one side of the rail (16) and a cam (68) from the opposite side. A cam (71) extends from the support (52) and runs between the cams (64) and (66) of the rail (16). A cam (70) extending from the support (54) is assigned to the cam (68).

Folglich kann sich die Abstützung (54) maximal zwischen der Abstützung (52) und den Nocken (68) relativ zu der Schiene (16) bewegen.As a result, the support (54) can move maximally between the support (52) and the cams (68) relative to the rail (16).

Von der der Schiene (16) zugewandten Seite der Stützschiene (28) gehen Nocken (72) und (74) aus, denen ein von der Abstützung (54) ausgehender Nocken (76) zugeordnet ist. Der Nocken (76) liegt folglich zwischen den Nocken (72) und (74) der Stützschiene (28), Anßenseitig weist die Stützschiene (28) einen Nocken (78) auf, dem ein Nocken (80) der Abstützung (52) zugeordnet ist.Cams (72) and (74) extend from that side of the support rail (28) which faces the rail (16) and to which a cam (76) extending from the support (54) is assigned. The cam (76) consequently lies between the cams (72) and (74) of the support rail (28). On the outside, the support rail (28) has a cam (78) to which a cam (80) of the support (52) is assigned .

Entsprechende Mitnehmer bzw. Begrenzer - und zwar in spiegelsymmetrischer Anordnung - weist die Stützschiene (30) auf, also einen außenliegenden Nocken (82) und zwei innenliegenden Nocken (84) und (86), denen Nocken (88) und (90) der Abstützungen (52) und (54) zugeordnet sind.Corresponding drivers or limiters - in a mirror-symmetrical arrangement - has the support rail (30), that is, an external cam (82) and two internal cams (84) and (86), the cams (88) and (90) of the supports (52) and (54) are assigned.

Werden nun die Schwellen (24) und (26) nach rechts bewegt (Fig. 2), wodurch sich die Brückenfuge verbreitert (Brückenfuge (12)), so erfassen die Nocken (72) und (84) der Stützschienen (28) und (30) die Nocken (76) und (90) der Abstützungen (52) und (54), so daß die Abstützung (54) nach rechts mitgenommen wird. Bei noch weiterer Verbreiterung der Brückenfuge (Brückenfuge (14)) werden auch die Nocken (80) und (88) von den außenliegenden Nocken (78) und (82) der Stützschienen (28) und (30) erfaßt, so daß gleichfalls ein Verschieben entlang der Schiene (16) erfolgt. Hierdurch erfolgt eine gleichmäßige Unterstützung der Schiene (16) im Bereich der Brückenfuge (14).If the sleepers (24) and (26) are moved to the right (FIG. 2), which widens the bridge joint (bridge joint (12)), the cams (72) and (84) of the support rails (28) and ( 30) the cams (76) and (90) of the supports (52) and (54), so that the support (54) is taken to the right. If the bridge joint (bridge joint (14)) is widened even further, the cams (80) and (88) are also removed from the outer cams (78) and (82) of the support rails (28) and (30) detected, so that there is also a displacement along the rail (16). This results in a uniform support of the rail (16) in the area of the bridge joint (14).

Verkleinert sich nun die Brückenfuge, so erfassen die Nocken (74) und (86) der Stützschienen (28) und (30) die Nocken (76) und (90) der Abstützung (54), so daß diese in Richtung der feststehenden Schwellen (20) und (22) verschoben werden.If the bridge joint becomes smaller, the cams (74) and (86) of the support rails (28) and (30) capture the cams (76) and (90) of the support (54) so that they move in the direction of the fixed sleepers ( 20) and (22) can be moved.

Die von der Schiene (16) ausgehenden Nocken (64), (66) und (68) und die diesen zugeordneten und von den Abstützungen (52) und (54) vorspringenden Nocken (70) und (71) sollen sicherstellen, daß die Unterstützungen (52) und (54), sofern sich diese z.B. gelöst haben sollten, nicht beliebig wandern bzw. sich verschieben können. Die Nocken (64), (68) können mit einem Stoßdämpferelement wie Federelement versehen sein, um bei größeren als vorgesehenen Bewegungen Wege der Stützplatten (52), (54) aufzunehmen, ohne daß die Nocken (64), (68) und (71) zerstört werden.The cams (64), (66) and (68) extending from the rail (16) and the cams (70) and (71) projecting from them and projecting from the supports (52) and (54) are intended to ensure that the supports (52) and (54), provided that these are, for example should have solved, not be able to hike or move arbitrarily. The cams (64), (68) can be provided with a shock absorber element, such as a spring element, in order to accommodate paths of the support plates (52), (54) in the event of larger movements than intended, without the cams (64), (68) and (71 ) are destroyed.

Eine besonders einfache Konstruktion zur Vergleichmäßigung der Abstände zwischen Schienenbefestigungspunkten wie Schwellen (22) und (24) und den zwischen und parallel zu diesen verlaufenden Abstützungen (52) und (54) ist der Fig. 4 zu entnehmen, So sind die Schwellen (22), (24) und Abstützungen (52) und (54) über Scheren (100) miteinander verbunden, deren Außenschenkel (102) und (104) an den Schwellen (22) und (24) angelenkt sind. Außenschenkel (102) und (104) sind gelenkig mit Innenschenkeln (106) und (108) verbunden, die mittig gelenkig an den Abstützungen (52) und (54) befestigt sind. Dabei verlaufen die Dreh- bzw. Befestigungs- bzw. Vergleichspunkte (110), (112), (114), (116), (118), (120) und (122) zwischen den Schenkeln (102), (104), (106) und (108) bzw. von den Schwellen (22), (24) und Abstützungen (52), (54) äquidistant zueinander.A particularly simple construction for equalizing the distances between rail fastening points such as sleepers (22) and (24) and the supports (52) and (54) running between and parallel to them can be seen in FIG. 4. Thus, the sleepers (22) , (24) and supports (52) and (54) connected to one another via scissors (100), the outer legs (102) and (104) of which are articulated to the sleepers (22) and (24). Outer legs (102) and (104) are connected in an articulated manner to inner legs (106) and (108), which are fastened in an articulated manner to the supports (52) and (54). The fulcrums, fastening points or comparison points (110), (112), (114), (116), (118), (120) and (122) run between the legs (102), (104), (106) and (108) or of the sleepers (22), (24) and supports (52), (54) equidistant from each other.
