Abstract

An arrangement for bridging expansion joints in carriageways, especially bridges. One or more parallel plates run at right-angles to the direction of the carriageway adjacent at the top to the surface of the carriageway. The plates are supported at the bottom on bars which run at right-angles to the expansion joint and transmit loads directly or indirectly into the edges of the joint adjacent thereto. For controlling the spacing of the plates, control cables are provided. The plates are connected to the cable runs of the control cables. The cable runs run parallel to the bars and are attached either to the load-transmitting bars themselves or to separate control bars.

Description

Die Erfindung betrifft eine Vorrichtung zum Überbrücken von Dehnungsfugen in Verkehrswegen, insbesondere Brücken, mit einer oder mehreren quer zur Verkehrswegrichtung verlaufenden, zueinander parallelen Lamellen, die nach oben an die Verkehrswegdecke angrenzen und nach unten auf quer zur Dehnungsfuge verlaufenden, in die daran angrenzenden Verkehrswegränder direkt oder indirekt lastabtragenden Traversen abgestützt sind, und wobei eine Einrichtung zur Steuerung der Lamellenabstände vorgesehen ist.The invention relates to a device for bridging expansion joints in traffic routes, in particular bridges, with one or more lamellae running parallel to the traffic route direction and parallel to one another, which adjoin the ceiling of the traffic route upwards and downward on traffic route edges which run transverse to the expansion joint, into the adjacent traffic route edges or indirectly supporting crossbeams, and a device for controlling the lamella spacing is provided.

Bei derartigen bekannten Vorrichtungen (z.B. Deutsche Patentschriften 16 58 611 und 30 19 594) besteht die Notwendigkeit, die Abstände zwischen den Lamellen in Anpassung an die jeweilige Weite der Dehnungsfugen und auch als Reaktion auf Brems- und Anfahrkräfte darüberfahrender Fahrzeuge zu steuern.In such known devices (e.g. German patents 16 58 611 and 30 19 594) there is a need to control the spacing between the lamellas in accordance with the respective width of the expansion joints and also in response to braking and starting forces of vehicles traveling over them.

Es sind zahlreiche Steuerungseinrichtungen bekannt, welche durch Einsatz unterschiedlicher Mittel wie Gelenkhebel, Scherengestänge, Zahnstangen, elastischer Steuerteile od. dgl. die Steuerung der Lamellen bewirken, derart, daß diese den Fugenspalt gleichmäßig unterteilen.There are numerous control devices knows which, by using different means such as articulated levers, scissors linkages, toothed racks, elastic control parts or the like, effect the control of the slats in such a way that these subdivide the joint gap evenly.

Die bekannten Hebelsteuerungen (z.B. Deutsche Offenlegungsschrift 24 21 964) besitzen keinerlei stoßdämpfende Wirkung; ihre Gelenke schlagen mit der Zeit aus.The known lever controls (e.g. German Offenlegungsschrift 24 21 964) have no shock-absorbing effect; their joints flap over time.

Die bekannten elastischen Steuereinrichtungen (z.B. Deutsche Patentschriften 16 58 611 und 30 19 594) sind weniger genau als die genannten Hebelsteuerungen, wobei die Ungenauigkeit mit kleiner werdenden Auslenkkräften, aber auch mit zunehmendem Alter der gummielastischen Steuerteile zunimmt.The known elastic control devices (e.g. German patents 16 58 611 and 30 19 594) are less precise than the lever controls mentioned, the inaccuracy increasing with decreasing deflection forces, but also with increasing age of the rubber-elastic control parts.

Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Steuereinrichtung an einer Vorrichtung der eingangs genannten Art zu schaffen, welche mit hoher Genauigkeit arbeitet, unmittelbar auf jede Auslenkung durch Verkehrsbelastungen reagiert und eine stoßartige Kraftübertragung vermeidet.In contrast, the present invention has for its object to provide a control device on a device of the type mentioned, which works with high accuracy, responds immediately to any deflection caused by traffic loads and avoids a sudden power transmission.

Diese Aufgabe wird nach dem erfindungsgemäßen Vorschlag dadurch gelöst, daß die Lamellen an Seilsträngen angeschlossen sind, die parallel zu den Traversen verlaufen und durch daran umlaufend geführte Steuerseile gebildet sind, wobei die beiden Seilstränge jedes Steuerseils jeweils mit einer Lamelle oder einem Verkehrswegrand verbunden sind und ihre geradlinige Erstrekkung wenigstens der Entfernung der beiden Verbindungspunkte bei maximaler Öffnung der Fuge entspricht.This object is achieved according to the proposal of the invention in that the slats on rope strings are connected, which run parallel to the trusses and are formed by control cables running all around them, the two cable strands of each control cable are each connected to a slat or a traffic route edge and their straight extension corresponds at least to the distance between the two connection points with maximum opening of the joint .

Die erfindungsgemäß vorgeschlagene Folgesteuerung ermöglicht die Steuerung einer einzigen, vereinzelter oder jeder Lamelle einer derartigen Überbrückungsvorrichtung. Die Steuerung erfolgt dabei entweder über lastabtragende Traversen und/oder über zusätzliche, nichtlastabtragende, der Steuerung dienende Traversen, sog. Steertraversen. Traversen einschließlich Steuertraversen sind jeweils nur mit einer Lamelle fest verbunden; die an den Traversen vorgesehenen Seilstränge sind jeweils mit einer Lamelle oder einem Verkehrswegrand verbunden.The sequence control proposed according to the invention enables the control of a single, isolated or each lamella of such a bridging device. The control takes place either via load-bearing crossbeams and / or via additional, non-loadbearing crossbeams that serve to control the system, so-called steer crossbeams. Trusses including control crossbars are only permanently connected to one slat; the rope strands provided on the traverses are each connected to a slat or a traffic route edge.

Ist nur eine einzige Lamelle vorhanden, so überbrücken die Traversen, auf welcher diese Lamelle abgestützt ist, die Dehnungsfuge und die Seilstränge sind jeweils mit einem Verkehrswegrand verbunden.If there is only a single slat, the crossbeams on which this slat is supported bridge the expansion joint and the cable strands are each connected to a traffic route edge.

Sind mehrere Lamellen vorhanden, so sind die dem jeweiligen Verkehrswegrand benachbarten Lamellen mit Traversen verbunden, deren Steuerseile mit einem Seilstrang am Fugenrand, mit dem anderen an der benachbarten Lamelle befestigt sind. Bei einer Vorrichtung der eingangs genannten Art mit nur zwei Lamellen trifft dies auf jede dieser Lamellen zu. Bei einer Vorrichtung mit mehr als zwei Lamellen sind die mittleren Lamellen an Traversen befestigt, deren Seilstränge jeweils mit einer benachbarten Lamelle verbunden sind. Anstelle der benachbarten Lamellen kommen auch andere von der Befestigungsstelle der steuernden Traverse noch weiter, für jede Ausführungsform jedoch untereinander gleich weit entfernte Lamellen in Frage.If there are several slats, they are adjacent lamellae connected to the respective traffic route edge with trusses, the control cables of which are attached to the edge of the joint with a rope strand, with the other to the adjacent lamella. In the case of a device of the type mentioned at the beginning with only two slats, this applies to each of these slats. In the case of a device with more than two lamellae, the middle lamellae are fastened to trusses, the cable strands of which are each connected to an adjacent lamellae. Instead of the adjacent lamellae, other lamellae that are equally far apart from the fastening point of the controlling crossmember are also possible.

Die Erfindung ist auch anwendbar auf solche Vorrichtungen, bei denen neben lastabtragenden Traversen sog. Steuertraversen vorhanden sind, die nur einen Teil der Dehnungsfuge überbrücken, also nicht von einem Verkehrswegrand zum anderen verlaufen. Mehrere derartiger Steuertraversen, die jeweils mit einer Lamelle fest verbunden sind, überbrücken in gestaffelter Anordnung die gesamte Dehnungsfuge, wobei alle Steuertraversen mit einem Steuerseil versehen sind. Dabei ist zweckmäßig, daß die beiden zu einr bestimmten Lamelle benachbarten Lamellen jeweils mit einem Seilstrang der mit der bestimmten Lamelle fest verbundenen Steuertraverse gekoppelt sind. Die aus derartigen Steuertraversen zusammengesetzte durchgehende Steuerkette kann gleichzeitig der Aufnahme von Vertikallasten dienen, nämlich wenn die mit einer Steuertraverse nicht fest verbundenen, z.B. von dieser gesteuerten, Lamellen auf der Steuertraverse gleitend oder über elastische, schubverformbare Lagerkörper abgestützt sind (vgl. Deutsche Patentschrift 30 19 594).The invention is also applicable to devices in which, in addition to load-bearing crossbeams, there are so-called control crossbeams which only bridge part of the expansion joint, ie do not run from one edge of the traffic route to the other. Several such control crossbars, each of which is firmly connected to a lamella, bridge the entire expansion joint in a staggered arrangement, all control crossbars being provided with a control cable. It is expedient that the two slats adjacent to a certain slat are each coupled to a cable strand of the control crossbar firmly connected to the certain slat are. The continuous control chain composed of such control crossbars can simultaneously serve to absorb vertical loads, namely if the slats not firmly connected to a control crossbar, for example slats controlled by it, are slidably supported on the control crossbar or are supported by elastic, thrust-deformable bearing bodies (cf. German patent specification 30 19 594).

Selbstverständlich ist es im Rahmen der Erfindung möglich, nicht alle Lamellen in der genannten Weise zu steuern, beispielsweise nur jede zweite, dritte usw. Lamelle zu steuern und dazwischen nicht gesteuerte Lamellen anzuordnen die sich über zwischen allen Lamellen vorhandenen elastischen Dichtungsprofilen gegeneinander und gegenüber den gesteuerten Lamellen horizontal abstützen.Of course, it is possible within the scope of the invention not to control all of the slats in the manner mentioned, for example only to control every second, third, etc. slat and to arrange non-controlled slats in between, which are located between all slats against each other and against the controlled elastic sealing profiles Support the slats horizontally.

Die erfindungsgemäß vorgeschlagene Seilsteuerung ist infolge der Seildehnung hinreichend elastisch, so daß störende Stoßbelastungen vermieden werden; sie ist im Rahmen der zugelassenen Dehnungen aber auch hinreichend genau, so daß schon bei verhältnismäßig kleinen Auslenkkräften Steuerbewegungen erzielt werden, denen zufolge die mit einer steuernden Traverse fest verbundene Lamelle mittig zwischen den beiden von dieser Traverse gesteuerten Lamellen, bzw. einer gesteuerten Lamelle und einem Fugenrand, eingestellt wird.The rope control proposed according to the invention is sufficiently elastic due to the rope stretching, so that disturbing shock loads are avoided; it is also sufficiently precise within the permitted stretches, so that control movements can be achieved even with relatively small deflection forces, according to which those are firmly connected to a steering crossmember Slat is set in the middle between the two slats controlled by this traverse, or a controlled slat and a joint edge.

Im folgenden werden Ausführungsbeispiele der Erfindung anhand der Zeichnung erläutert. Es zeigt

  • Fig. 1 einen vertikalen Querschnitt durch eine Überbrückungsvorrichtung mit nur einer Lamelle,
  • Fig. 2 eine Ansicht von unten auf eine Überbrückungsvorrichtung mit mehreren Lamellen und sog. Steuertraversen,
  • Fig. 3 einen horizontalen Schnitt durch ein Ende einer Steuertraverse und
  • Fig. 4 einen Schnitt gem. IV-IV der Fig. 3.
Exemplary embodiments of the invention are explained below with reference to the drawing. It shows
  • 1 is a vertical cross section through a bridging device with only one lamella,
  • 2 is a bottom view of a bridging device with a plurality of lamellae and so-called control cross members,
  • Fig. 3 shows a horizontal section through one end of a control crossbar and
  • Fig. 4 shows a section. IV-IV of FIG. 3.

Gem. Fig. 1 ist zwischen einem linken Verkehrswegrand 1 und einem rechten Verkehrswegrand 2 eine einzige Lamelle 3 angeordnet. In Ausschnitten 4 der Verkehrswegränder sind jeweils die Enden einer die Dehnungsfuge 5 überbrückenden lastabtragenden Traverse 6 zwischen oberen Lagerteilen 7 und unteren Lagerteilen 8 verschieblich gelagert. Auf der Traverse 6 ist die Lamelle 3 abgestützt, indem sie über ein Zwischenstück 9 fest mit der Traverse 6 verbunden ist. Die Fugenränder bestehen bevorzugt aus Beton, können im Randbereich aber auch durch eine Stahlkonstruktion armiert sein. Lamelle 3, Traverse 6, Zwischenstück 9 bestehen bevorzugt aus Stahl, wobei das Zwischenstück 9 einerseits mit der Lamelle 3 andererseits mit der Traverse 6 verschweißt ist. Die Lagerteile 7, 8 sind bevorzugt in vertikaler Richtung elastisch vorgespannte Kunststoffblöcke, z.B. aus Neoprene. Auf einer Seite der Traverse 6 sind an beiden Enden Umlenkrollen 10 befestigt, über welche ein Steuerseil 11 geführt ist. Das Steuerseil 11 besteht bevorzugt aus einer geschlossenen Seilschlaufe in Art eines Endlosseils, wobei die Seilenden mittels einer nicht näher dargestellten Spann- bzw. Nachspannvorrichtung verbunden sind. Das Steuerseil kann aber auch an jeder Befestigungsstelle unterbrochen sein. Das Steuerseil 11 umfaßt zwei Seilstränge, nämlich einen oberen Seilstrang 12 und einen unteren Seilstrang 13. Der obere Seilstrang 12 ist über eine Befestigungsstelle in Art einer Klemme 14 mit dem linken Fugenrand 1, der untere Seilstrang 13 ist über eine weitere Klemme 15 mit dem rechten Fugenrand 2 verbunden. Die Zwischenräume zwischen den beiden Fugenrändern 1, 2 und der Lamelle 3 sind mittels nicht gezeigter elastischer Dichtungsprofile abgedichtet. Bei jeder Veränderung der Breite der Dehnungsfuge 5 verursacht eine entsprechende Entfernung oder Annäherung der beiden Klemmen 14, 15 zwingend die Aufrechterhaltung der Mittelstellung der Lamelle 3. Selbstverständlich ist die Lamelle 3 auf mehreren Traversen 6 abgestützt, wobei sich die Anzahl der Traversen nach der Breite des Verkehrsweges richtet, mindestens aber zwei beträgt.According to FIG. 1, a single lamella 3 is arranged between a left-hand traffic route edge 1 and a right-hand traffic route edge 2. In sections 4 of the traffic route edges are the ends of a load-bearing cross member 6 bridging the expansion joint 5 between the upper bearing parts 7 and lower bearing parts 8 slidably mounted. The lamella 3 is supported on the crossmember 6 by being firmly connected to the crossmember 6 via an intermediate piece 9. The joint edges are preferably made of concrete, but can also be reinforced by a steel structure in the edge area. Lamella 3, cross member 6, intermediate piece 9 are preferably made of steel, the intermediate piece 9 being welded to the lamella 3 on the one hand and to the cross member 6 on the other hand. The bearing parts 7, 8 are preferably elastically prestressed plastic blocks in the vertical direction, for example made of neoprene. On one side of the crossmember 6, deflection rollers 10 are fastened at both ends, via which a control cable 11 is guided. The control cable 11 preferably consists of a closed cable loop in the manner of an endless cable, the cable ends being connected by means of a tensioning or tensioning device (not shown in more detail). The control cable can also be interrupted at any attachment point. The control rope 11 comprises two rope strands, namely an upper rope strand 12 and a lower rope strand 13. The upper rope strand 12 is via a fastening point in the manner of a clamp 14 with the left joint edge 1, the lower rope strand 13 is via a further clamp 15 with the right one Joint edge 2 connected. The spaces between the two joint edges 1, 2 and the lamella 3 are with sealed by means of elastic sealing profiles, not shown. With each change in the width of the expansion joint 5, a corresponding removal or approach of the two clamps 14, 15 necessarily causes the central position of the lamella 3 to be maintained. Of course, the lamella 3 is supported on a plurality of cross members 6, the number of cross members depending on the width of the Traffic route aimed, but at least two.

Fig. 2 zeigt einen Ausschnitt aus einer Überbrückungsvorrichtung für eine breite Dehnungsfuge, wobei fünf Lamellen in der Ansicht von unten gezeichnet sind. Die beiden äußeren Lamellen 16 können gleichbedeutend entweder als frei bewegliche Lamellen, so wie die drei mittleren Lamellen 17 aufgefaßt werden; sie können aber auch als fest mit den Verkehrswegrändern verbundene Randlamellen aufgefaßt werden. Für das Steuerungsprinzip ergibt sich hieraus kein Unterschied. Falls die äußeren Lamellen 16 sog. Randlamellen darstellen, können die drei gezeigten allein der Steuerung dienenden, also keine Vertikallasten abtragenden Steuertraversen 18 eine geschlossene, die beiden Verkehrswegränder verbindende Steuerkette bilden; andernfalls wäre diese Steuerkette durch weitere Steuertraversen fortzusetzen. Die lastabtragenden Traversen sind in dem Ausschnitt gem. Fig. 2 nicht dargestellt.Fig. 2 shows a section of a bridging device for a wide expansion joint, with five lamellae are shown in the view from below. The two outer slats 16 can either be interpreted as freely movable slats, as the three middle slats 17; but they can also be understood as edge lamellae permanently connected to the edges of the traffic route. There is no difference for the control principle. If the outer lamellae 16 represent so-called edge lamellae, the three control traverses 18 which are used solely for the control and therefore do not remove vertical loads can form a closed control chain connecting the two traffic route edges; otherwise would be to continue this control chain with further control beams. The load-bearing crossbeams are gem. Fig. 2 not shown.

Die Verbindungsstellen 19 der Steuertraversen 18 mit den ihnen zugeordneten Lamellen 17 sind jeweils durch eine gitterartige Struktur eingezeichnet. An den Enden der Steuertraversen 18 sind Umlenkstücke 26 mit halbkreisförmigen Gleitbahnen vorgesehen. Gem. Fig. 3 könen diese Umlenkstücke aus einem harten Elastomer geformte Klemmteile 20 sein, welche auf das Ende 21 des Steges 22 eines die Teiltraversen bildenden Doppel-T-Profils 23 aufgesteckt sind. Das elastomere Klemmteil 20 unterstützt vorteilhaft die Elastizität der Steuerung. Anstelle derartiger Umlenkstücke 26 können auch um vertikale Achsen drehende Seilrollen vorgesehen sein.The connection points 19 of the control traverses 18 with the slats 17 assigned to them are each drawn in by a lattice-like structure. At the ends of the control crossbeams 18 deflection pieces 26 with semicircular slideways are provided. According to FIG. 3, these deflection pieces can be formed from a hard elastomeric clamping parts 20 which are plugged onto the end 21 of the web 22 of a double T-profile 23 which forms the partial cross members. The elastomeric clamping part 20 advantageously supports the elasticity of the control. Instead of such deflection pieces 26, rope pulleys rotating about vertical axes can also be provided.

Die Schnittdarstellung gem. Fig. 4 zeigt ein derartiges Klemmteil 20 mit einer vertieften Gleitbahn 24, in welcher ein bandförmiges Steuerseil 25, welches aus drei nebeneinander liegenden Einzelseilen und einer Auflage 28 aus Gleitwerkstoff, z.B. PTFE, zusammengesetzt ist, gleitend geführt ist. Derartige Steuerseile 25 umgeben auch die in Fig. 2 dargestellten Steuertraversen 18, derart, daß die gegenüberliegenden Seilstränge dieser Steuerseile in waagrechten Ebenen liegen. Die beiden Seilstränge sind zwischen zwei gegenüberliegenden Umlenkstükken 26 frei gespannt und jeweils über eine Klemme 27 mit einer Lamelle 16, 17 verbunden. Alle über eine einzelne Lamelle oder über die Verkehrswegränder eingeleiteten horizontalen Verschiebungen werden mittels der Steuerseile 25 auf alle Lamellen bzw. Verkehrswegränder übertragen, mit dem Ergebnis, daß sich die Lamellen 16, 17 so einstellen, daß deren gegenseitige Abstände sowie die Abstände der äußeren Lamellen von den Verkehrswegrändern gleichgroß sind.The sectional view acc. Fig. 4 shows such a clamping part 20 with a recessed slideway 24, in which a band-shaped control cable 25, which is composed of three adjacent individual ropes and a support 28 made of sliding material, for example PTFE, is slidably guided. Such control cables 25 surround also the control crossbeams 18 shown in FIG. 2, such that the opposite cable strands of these control cables lie in horizontal planes. The two rope strands are freely stretched between two opposite deflection pieces 26 and each connected to a lamella 16, 17 via a clamp 27. All of the horizontal displacements introduced via a single lamella or over the edges of the traffic routes are transmitted by means of the control cables 25 to all the lamellas or traffic route edges, with the result that the lamellae 16, 17 adjust such that their mutual distances and the distances between the outer lamellae the edges of the traffic routes are the same size.
