Abstract

Die Vorrichtung dient dem Überbrücken von Dehnungsfugen in einer Fahrbahn von grösseren Bauwerken, wie Brücken oder Viadukte. Der tragende Teil besteht aus Trägern (2), deren Oberseite bündig mit der Fahrbahn verläuft. Die Träger (2) stützen sich auf Traversen (1), die in unterhalb der Fahrbahn angeordneten Nischen (N) verschiebbar gelagert sind. Die Teilspalten zwischen den Trägern sind durch gummielastische Streifen abgedichtet. Damit eine Dehnung oder Kontraktion des Bauwerkes sich gleichmässig über die Teilspalten verteilt, werden die Traversen mit Hilfe von Lenkern (4) gesteuert. Die Enden dieser Lenker sind gelenkig mit den einander gegenüberliegenden Fugenrändern verbunden. Im Gegensatz zu bekannten Vorrichtungen dieser Art, bei denen die Lenker unterhalb der Traversen angeordnet sind, führen hier die Lenker (4) durch die Traversen hindurch. Dazu ist in den Traversen ein Lager (10) mit Kunststofflagerschalen (40) eingebaut, das sowohl eine Verschiebung als ein Schwenken des jeweiligen Lenkers in der Traverse erlaubt.The device is used to bridge expansion joints in a roadway of larger buildings, such as bridges or viaducts. The load-bearing part consists of beams (2), the top of which is flush with the road. The beams (2) are supported on crossbeams (1), which are slidably mounted in niches (N) arranged below the carriageway. The partial gaps between the beams are sealed by elastic strips. So that an expansion or contraction of the structure is evenly distributed over the sub-columns, the traverses are controlled with the help of handlebars (4). The ends of these links are articulated to the opposite joint edges. In contrast to known devices of this type, in which the links are arranged below the crossbars, the links (4) lead through the crossbars here. For this purpose, a bearing (10) with plastic bearing shells (40) is installed in the crossbeams, which allows both displacement and pivoting of the respective link in the crossbeam.

Description

Die vorliegende Erfindung betrifft eine Ueberbrückungs-Vorrichtung für Dehnungsfugen in Fahrbahnen von Brücken oder dergleichen mit quer zur Fahrbahn-Längsrichtung verlaufenden, elastischen Dichtungsstreifen, die jeweils zwischen parallel zueinander verlaufenden Trägern angebracht sind, deren Oberseite bündig zur Fahrbahn-Oberfläche verläuft, und die je mit einer Traverse verbunden sind, welch letztgenannte in Gruppen zusammengefasst - und in beidseits des Fugenspaltes in unterhalb der Fahrbahn befindlichen Nischen längsverschiebbar gelagert sind, wobei die Längsverschiebung der Traversen mittels eines Lenkers erfolgt, dessen Enden aneinander gegenüberliegenden Seiten des Fugenspaltes gehalten sind.The present invention relates to a bridging device for expansion joints in carriageways of bridges or the like with elastic sealing strips running transversely to the longitudinal direction of the carriageway, each of which is attached between supports running parallel to one another, the top of which is flush with the carriageway surface, and each with are connected to a traverse, the latter of which are grouped together - and are mounted so as to be longitudinally displaceable in niches located below the carriageway on both sides of the joint gap, whereby the longitudinal displacement of the crossbeams takes place by means of a link, the ends of which are held on opposite sides of the joint gap.

Eine derartige Ueberbrückungs-Vorrichtung für Dehnungsfugen mit einer sogenannten Zwangs-Steuerung der Traversen ist durch die CH-PS 494316 bekannt.Such a bridging device for expansion joints with a so-called forced control of the trusses is known from CH-PS 494316.

Bei dieser bekannten Fugen - Ueberbrückungs-Vorrichtung ist der Lenker unter den Traversen angeordnet. Jede Traverse ist mit einem nach unten ragenden Zapfen versehen, der unter Zwischenschaltung eines Gleitsteines in eine Längsnut des Lenkers eingreift.In this known joint - bridging device, the handlebar is arranged under the crossbars. Each traverse is provided with a downwardly projecting pin which engages in a longitudinal groove in the handlebar with the interposition of a sliding block.

Bei Aenderungen der Fugenspaltbreite durch Dehnung oder Kontraktion der angrenzenden Bauteile muss der tief unter der Fahrbahnoberfläche liegende Lenker die Traversen mit dem auf ihnen aufliegenden bis zur Fahrbahnoberfläche emporragenden Träger verschieben.If the joint gap width changes due to expansion or contraction of the adjacent components, the handlebars located deep below the road surface must move the crossbeams with the beam resting on them up to the road surface.

Andererseits werden beim Beschleunigen oder Bremsen des über die Ueberbrückungs-Vorrichtung rollenden Verkehrs, Kraft auf die Träger und von dort über die Traversen, den Lagerzapfen und den Nutensteinen auf den Lenker übertragen. Die Uebertragung der Kräfte die durch den rollenden Verkehr verursacht werden, erfolgt daher über diverse Lagerstellen mit einem relativ grossen Hebelarm. Die dauernde Wechselwirkung der Kräfte führt zu einem starken Verschleiss der Lagerstellen. Ausgeschlagene Lager aber verursachen beim Ueberfahren der Ueberbrückungs-Vorrichtung erhebliche Geräusche.On the other hand, when the traffic rolling over the bridging device is accelerated or braked, force is transmitted to the carriers and from there via the crossbeams, the bearing journal and the sliding blocks to the handlebars. The transfer of forces through the rolling traffic caused, therefore takes place via various bearing points with a relatively large lever arm. The constant interaction of the forces leads to heavy wear on the bearing points. Knocked out bearings cause considerable noise when the bridging device is passed over.

Der Erfindung liegt die Aufgabe zugrunde, für eine Ueberbrückungs-Vorrichtung der eingangs angegebenen Art eine Zwangssteuerung zu schaffen bei der die Kraftübertragung von den Traversen auf den Lenker über möglichst wenig Lagerteile und möglichst kleinem Hebelarm erfolgt.The invention has for its object to provide a positive control for a bridging device of the type mentioned in which the power transmission from the traverses to the handlebars takes place via as few bearing parts and the smallest possible lever arm.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der Lenker schwenkbar und axial verschiebbar durch die Traversen hindurchgeführt ist.This object is achieved according to the invention in that the handlebar is pivotally and axially displaceable through the cross members.

In der Zeichnung sind Ausführungsbeispiele des Erfindungsgegenstandes vereinfacht dargestellt und anhand der nachfolgenden Beschreibung erläutert.Exemplary embodiments of the subject matter of the invention are shown in simplified form in the drawing and are explained on the basis of the following description.

Der, der Dilatationsbewegung der Bauteile Bl, B2 in Breitenrichtung variable Fugenspalt F verläuft meist senkrecht zur Fahrbahnlängsrichtung . Die Ueberbrückungs-Vorrichtung der Fahrbahn ist in einer Position dargestellt, die genau einer Mittellage zwischen maximaler und minimaler Fugenbreite entspricht. Ueber die gesamte Fugenlänge sind in bestimmten Abständen Gruppen von Traversen 1 angeordnet. Die Anzahl der Traversen 1 pro Gruppe entspricht genau der Anzahl der senkrecht zu den Traversen 1 und in Längsrichtung der Fuge verlaufenden Trägern 2. Die Träger erstrecken sich über die gesamte Länge des Fugenspaltes, wobei sie mehrere Gruppen von Traversen überqueren. Jeder Träger 2 ist fest mit einer ihr zugeordneten Traverse 1 der Gruppe verbunden, vorzugsweise verschweisst. Die den Fugenspalt F überquerenden Traversen 1 ragen in beidseits der Fuge angebrachte Nischen N hinein. Die beiden Enden des Lenkers 4 sind mittels Streben 3 an einander gegenüberliegenden Seiten des Fugenspaltes gehalten. Die Zeichnung zeigt eine mittlere Breitenausdehnung des Fugenspaltes bei der der Lenker genau in Längsrichtung der Fuge verläuft. Wird die Fuge durch Dehnung der Bauteile enger oder durch kontraktion der Bauteile breiter, schwenkt der Lenker und sorgt dafür, dass sämtliche von elastischen Dichtungsstreifen überbrückten Teilspalten zwischen den Trägern sich alle gleich viel verbreitern oder verschmälern.The joint gap F, which is variable in the width direction due to the dilatation movement of the components B1, B2, usually runs perpendicular to the longitudinal direction of the carriageway. The bridging device of the carriageway is shown in a position which corresponds exactly to a central position between the maximum and minimum joint width. Groups of trusses 1 are arranged at certain intervals along the entire length of the joint. The number of trusses 1 per group corresponds exactly to the number perpendicular to the trusses 1 and in the longitudinal direction of the joint-running girders 2. The girders extend over the entire length of the joint gap, crossing over several groups of trusses. Each carrier 2 is firmly connected, preferably welded, to a cross member 1 of the group assigned to it. The traverses 1 crossing the joint gap F project into niches N provided on both sides of the joint. The two ends of the link 4 are held by means of struts 3 on opposite sides of the joint gap. The drawing shows an average width expansion of the joint gap in which the link runs exactly in the longitudinal direction of the joint. If the joint becomes narrower due to stretching of the components or wider due to contraction of the components, the handlebar swivels and ensures that all the gaps between the beams bridged by elastic sealing strips all widen or narrow equally.

Da der Abstand zwischen dem Zapfen 31 durch die der Lenker 4 mit den Streben 3 verbunden ist einen festen Wert hat, müssen die Streben 3 schwenkbar am Fugenrand gehalten sein wie dies später an Hand von Figur 4 erläutert wird. Der Lenker 4 durchsetzt sämtliche Traversen 1, einer Gruppe. In den Traversen 1 ist der Lenker 4 in besonders ausgebildeten Laqern 10, 40 qeführt.Since the distance between the pin 31 through which the link 4 is connected to the struts 3 has a fixed value, the struts 3 must be pivotally held at the joint edge, as will be explained later with reference to FIG. 4. The handlebar 4 passes through all the trusses 1, a group. In the crossbeams 1, the handlebar 4 is guided in specially designed bearings 10, 40.

Die Traversen 1 sind verschiebbar auf einem in der Nische N angebrachten Auflagestreifen 6 gelagert. Diese Auflagestreifen 6 bestehen vorzugsweise aus Tetrafluoräthylen, die mit Schmiermitteltaschen versehen sein können.The cross members 1 are slidably mounted on a support strip 6 provided in the niche N. These support strips 6 are preferably made of tetrafluoroethylene, which can be provided with lubricant pockets.

Die Träger 2 sind jeweils nur mit einer Traverse 1 der Gruppe fest verbunden und überqueren die übrigen Traversen dieser Gruppe mit Spiel wie in Figur 2 ersichtlich.The beams 2 are each firmly connected to only one cross member 1 of the group and cross the other cross members of this group with play as can be seen in FIG. 2.

Die Lager 10, 40 sind so ausgebildet, dass sie dem Lenker sowohl ein Gleiten in axialer Richtung als ein Schwenken erlauben. Durch den Einbau der Lager 10, 40 in die Traverse wird eine möglichst günstige Kraftübertragung zwischen dem Lenker und den Traversen erreicht.The bearings 10, 40 are designed such that they allow the handlebar to slide in the axial direction as well as to pivot. By installing the bearings 10, 40 in the crossmember, the best possible power transmission between the handlebar and the crossmembers is achieved.

Die Figuren 2 und 3 zeigen eine Traverse 1 in Form eines Doppel T-Balkens in dessen Steg, auf etwa halber Höhe ein Lagergehäuse 10 eingebaut ist, das inwendig zylindrisch konkav bearbeitet ist. In diesem Gehäuse ist das eigentliche Lager 40 eingesetzt, das eine zylindrische Aussenform mit einer senkrecht zur Zylinderachse angebrachten, dem Lenkerquerschnitt entsprechenden Durchgangsöffnung versehen ist. Das Lager ist vorzugsweise aus einem Kunststoff mit guten Gleiteigenschaften z.B. aus Tetrafluoräthylen gefertigt. Es kann einstückig oder aus Teilen zusammengesetzt sein. Das Lagergehäuse 10 ist im Steg der Traverse eingeschweisst. Die Anordnung erlaubt ein beidseitiges Schwenken des Lenkers um einen Winkele. Figur 4 zeigt die Strebe 3 in grösserem Masstab. Der mittlere Teil 32 besteht aus einem massiven Stab, einem Hohlprofil oder Profilleisten an dessen Ende eine U-förmige Lageröse 33 angeschweisst ist, die mittels des Gelenkbolzens 31 die Verbindung mit einem Ende des Lenkers 4 herstellt. Wie bereits erwähnt verläuft bei einer Verstellung der Fugenbreite F die Längsachse des Lenkers schräg zur Fugenlängsachse. Damit dies möglich ist, ist die Strebe schwenkbar an einer Lasche 34 die am Nischenkasten N angebracht ist, gehalten. Zwei gummielastische Scheiben 35 sind vorgesehen die ein schwenken der Strebe um wenige Grad erlauben. Statt beide Streben so auszubilden könnte auch eine Strebe starr angeordnet sein. Die andere Strebe kann dann elastisch gehalten sein, oder ebenfalls starr ausgebildet und mit einem ähnlichen Lager wie die Traversen versehen sein, in dem dass der Lenker schwenkbar und längsverschiebbar gehalten ist. Die möglichen Varianten sind in den Figuren 12-15 schematisch dargestellt. Figur 12 zeigt zwei schwenkbar angeordnete Streben 3 an deren Enden der Lenker 4 gelenkig gehalten ist.Figures 2 and 3 show a cross member 1 in the form of a double T-beam in the web, at about half the height of a bearing housing 10 is installed, which is machined inside concave cylindrical. The actual bearing 40 is used in this housing, which is provided with a cylindrical outer shape with a through opening which is arranged perpendicular to the cylinder axis and corresponds to the handlebar cross section. The bearing is preferably made from a plastic with good sliding properties, for example from tetrafluoroethylene. It can be in one piece or in parts be composed. The bearing housing 10 is welded into the crosspiece web. The arrangement allows the handlebars to be pivoted on both sides by an angle. Figure 4 shows the strut 3 on a larger scale. The middle part 32 consists of a solid rod, a hollow profile or profile strips at the end of which a U-shaped bearing eyelet 33 is welded, which establishes the connection to one end of the link 4 by means of the articulated bolt 31. As already mentioned, when the joint width F is adjusted, the longitudinal axis of the handlebar runs obliquely to the longitudinal axis of the joint. So that this is possible, the strut is pivotally held on a tab 34 which is attached to the niche box N. Two rubber-elastic disks 35 are provided which allow the strut to pivot by a few degrees. Instead of designing both struts in this way, one strut could also be arranged rigidly. The other strut can then be held elastically, or can also be rigid and provided with a bearing similar to that of the crossbeams, in that the handlebar is pivotably and longitudinally displaceable. The possible variants are shown schematically in FIGS. 12-15. Figure 12 shows two pivotably arranged struts 3 at the ends of the link 4 is articulated.

Figur 13 zeigt eine gelenkig und eine starr am Fugenrand befestigte Strebe 3'. In diesem Fall ist die Auslenkung der Strebe 3 entsprechend grösser.Figure 13 shows one articulated and one rigid at the edge of the joint attached strut 3 '. In this case, the deflection of the strut 3 is correspondingly greater.

Figur 14 zeigt eine weitere Variante mit zwei starr an den Fugenrändern befestigten Streben 3' und 3". Der Lenker 4 ist an der Strebe 3' schwenkbar und an Strebe 3" schwenkbar und axial verschiebbar gehalten. Figur 15 schliesslich zeigt zwei starre Streben 3" in denen der Lenker 4 beiderends gelenkig und axial verschiebbar gehalten ist. Es muss dabei natürlich Vorsorge getroffen werden, dass der Lenker sich nicht aus den Lagern schiebt. Die Figuren 5-8 zeigen Varianten eines Traversenlagers. Sind die Traversen höher braucht das Lager für den Lenker nicht eingeschweisst zu werden, sondern kann auf den Steg aufgeschraubt werden. Figur 5 zeigt ein derartiges Lager 50 von vorne, Fig. 6 von der Seite und in Figur 7 längs der Schnittlinie VII-VII in Figur 5 wobei die Traverse 1 im Schnitt erscheint. Das Kunststofflager 51 ist ähnlich ausgebildet wie das Lager 40 in Fiqur 3.FIG. 14 shows a further variant with two struts 3 'and 3 "rigidly attached to the joint edges. The link 4 is pivotable on the strut 3' and pivotable on the strut 3" and axially displaceable. Finally, FIG. 15 shows two rigid struts 3 "in which the handlebar 4 is articulated and axially displaceable at both ends. Of course, precautions must be taken to ensure that the handlebar does not slide out of the bearings. FIGS. 5-8 show variants of a truss bearing. If the crossbeams are higher, the bearing does not need to be welded in for the handlebars, but can be screwed onto the web, Figure 5 shows such a bearing 50 from the front, Figure 6 from the side and in Figure 7 along the section line VII-VII in 5 with the crossbeam 1 appearing in section 1. The plastic bearing 51 is configured similarly to the bearing 40 in FIG. 3.

Diese Form des Kunststofflagers lässt sich leicht montieren oder gegebenenfalls ersetzen wenn Verschleiss auftritt. Dabei geht man so vor, dass man zuerst den Lenker 4 aus dem Lager herauszieht. Jetzt kann die Lagerschale 40 bzw 51 um 90° gedreht und aus dem Lagergehäuse 10 bzw. 50 herausgenommen werden wie Figur 8 zeigt Das Querschnittprofil der Lagerschale ist vorzugsweise U-förmig sodass es sowohl die seitliche Führung als den Auflagedruck des Lenkers 4 aufnehmen kann. Die Figuren 9-11 zeigen eine Traverse 11 mehr im Detail. Sie umfasst eine U-förmige aus schmiedbarem Gusseisen hergestellte Lagerschale 10 die zylindrisch ausgedreht ist, zwischen zwei Abschnitten 11 eine I Profils eingeschweisst und oben durch ein angeschweisstes Flacheisen 12 abgedeckt ist. Damit die Enden der Traverse leicht auf der in den Nischen angebrachten Tetrafluoräthylen - Leisten 6 (s. Fig. 2) gleiten, ist unten an der Traverse ein poliertes Blech 13 aus rostfreiem Stahl angebracht. Es ist dazu U-förmig gebogen und an den Seiten des Flansches mittels Schweisspunkten 14 befestigt.This form of plastic bearing can be easily assembled or replaced if wear occurs. The procedure is to first pull the handlebar 4 out of the bearing. Now the bearing shell 40 or 51 can be turned 90 ° and out of the bearing housing 10 or 50 The cross-sectional profile of the bearing shell is preferably U-shaped so that it can accommodate both the lateral guidance and the contact pressure of the handlebar 4. Figures 9-11 show a traverse 11 in more detail. It comprises a U-shaped bearing shell 10 made of forgeable cast iron, which is turned out cylindrically, an I profile is welded between two sections 11 and is covered at the top by a welded flat iron 12. To ensure that the ends of the crossbar slide easily on the tetrafluoroethylene strips 6 (see FIG. 2) fitted in the recesses, a polished stainless steel plate 13 is attached to the bottom of the crossbar. For this purpose, it is bent in a U-shape and fastened to the sides of the flange by means of welding points 14.

In Erdbebengebieten wo sich die Baukörper beidseitig der Fuge heben oder senken, seitlich verschieben oder gar verwinden, kann es von Vorteil sein, die Traversenlager so auszubilden, dass sie diesen Bewegungen bis zu einem gewissen Grade folgen können. Beispielsweise könnte das Kunststofflager 51 kugelförmig statt zylindrisch ausgebildet sein und das Gehäuse 50 eine entsprechende Hohlkugelform aufweisen. Die Gleitlager in den Nischen und die Streben müssten dass ebenfalls so ausgebildet sein, dass sie die Bewegungen der Traversen mitmachen können.In earthquake areas where the structures rise or fall on both sides of the joint, move laterally or even twist, it can be advantageous to design the truss supports so that they can follow these movements to a certain degree. For example, the plastic bearing 51 could be spherical instead of cylindrical and the housing 50 could have a corresponding hollow spherical shape. The slide bearings in the niches and the struts should also be designed so that they can follow the movements of the trusses.

Die Figuren 16 und 17 zeigen ein Traversenlager das ähnlich aufgebaut ist wie das Lager nach Figur 3. Das Lagergehäuse besteht hier aus einem in der Traverse 1, eingeschweissten rechteckigen Rahmen 15, der nach dem Schweissen genau bearbeitet ist. In den Rahmen 15 ist zuerst ein Boden 53 (Figur 17) eingelegt und danach sind die Hohlzylindrisch bearbeiteten Lagerstücke 54 in den Rahmen eingesetzt.FIGS. 16 and 17 show a crossbeam bearing which is constructed similarly to the bearing according to FIG. 3. The bearing housing here consists of a rectangular frame 15 welded into the crossbar 1, which is precisely machined after welding. First, a bottom 53 (FIG. 17) is inserted into the frame 15 and then the hollow cylindrical machined bearing pieces 54 are inserted into the frame.

Diese Anordnung erlaubt daher das Auswechseln sämtlicher Verschleissteile des Lagers.This arrangement therefore allows all wear parts of the bearing to be replaced.
