Description

Die vorliegende Erfindung betrifft ein befahrbares Bauwerk, mit einem Überbau, einem Widerlager und einer Überbrückungsvorrichtung für eine zwischen dem Widerlager und dem Überbau angeordnete Dehnfuge, wobei das Widerlager und der Überbau angrenzend an die Dehnfuge Aussparungen aufweisen, die mit Polymerbeton verfüllt sind, in den jeweils ein flacher, leistenförmiger Halteabschnitt eines metallischen Randprofils eingebettet ist, und sich zwischen den beiden Randprofilen ein elastisches Dichtprofil erstreckt, welches dichtend an die beiden Randprofile angeschlossen ist. LU 82 203 A1 beschreibt ein Bauwerk mit den Merkmalen des Oberbegriffs des Anspruchs 1.The present invention relates to a driveable structure, comprising a superstructure, an abutment and a bridging device for an expansion joint arranged between the abutment and the superstructure, wherein the abutment and the superstructure adjacent to the expansion joint have recesses which are filled with polymer concrete in the respective a flat, strip-shaped holding portion of a metallic edge profile is embedded, and extending between the two edge profiles an elastic sealing profile, which is sealingly connected to the two edge profiles. LU 82 203 A1 describes a building with the features of the preamble of claim 1.

Überbrückungsvorrichtungen, wie sie insbesondere an Straßenbrücken zum Einsatz kommen, um die durch Wärmedehnungen verursachten Änderungen der Länge des Überbaus zu kompensieren, sind in unterschiedlichen Ausführungen bekannt und im Einsatz. Unterschieden werden dabei insbesondere Überbrückungsvorrichtungen mit Lamellen, welche innerhalb des Fugenspalts zwischen und parallel zu den Fugenrändern angeordnet sind und sich auf die Dehnfuge überbrückenden Traversen abstützen, einerseits und lamellenfreie Überbrückungsvorrichtungen andererseits. Überbrückungsvorrichtungen mit Lamellen sind in besonderer Weise dazu geeignet, Dehnfugen mit einem vergleichsweise großen Arbeitsbereich (Differenz zwischen maximaler und minimaler Fugenbreite) zu überbrücken. Sie sind indessen relativ teuer in der Herstellung, benötigen einen großen Einbauraum, und auch der Einbau ist aufwendig und zeitraubend. Aus diesem Grunde ist man bestrebt, Überbrückungsvorrichtungen ohne Lamellen zu verwenden, bei denen sowohl die Herstellung als auch der Einbau mit geringerem Aufwand verbunden sind. Besonders attraktiv unter Gesichtspunkten sowohl der Wirtschaftlichkeit als auch des benötigten Einbauraumes sind dabei Überbrückungsvorrichtungen der eingangs angegebenen Art, wie sie u.a. in der - nach dem Prioritätstag der vorliegenden Anmeldung veröffentlichten - Firmenschrift "Einzellige Fuge Typ RE mit Robo®Flex" der Mageba SA, CH-Bülach beschrieben sind. Diese Überbrückungsvorrichtungen lassen sich innerhalb kürzester Zeit verbauen, da die Randprofile nicht über entsprechende Anker mechanisch direkt an der Tragkonstruktion des Überbaus bzw. des Widerlagers (d.h. im Falle der Ausführung von Widerlager und Überbau mit einer Unterkonstruktion und einem darauf aufgebrachten Fahrbahnbelag an der Unterkonstruktion) sondern vielmehr über ihre flachen, leistenförmigen Halteabschnitte in dem die Aussparungen des Widerlagers bzw. des Überbaus ausfüllenden Polymerbeton verankert sind. Unter "Einbetten" der - i.a. in einer im wesentlichen horizontalen Ebene angeordneten - Halteabschnitte der Randprofile in dem Polymerbeton ist dabei zu verstehen, daß die Halteabschnitte zumindest zu einem überwiegenden Anteil in den Polymerbeton eintauchen, so daß zumindest über und unter den Halteabschnitten Polymerbeton vorgesehen ist. Diese Verankerung der Randprofile über deren in den Polymerbeton eingebetteten Halteabschnitte schließt allerdings nicht aus, daß die Randprofile im Einzelfall ergänzend auch punktuell mechanisch direkt an der jeweiligen Tragkonstruktion abgestützt sein können, wobei sich mittels entsprechender Montageabstützungen, welche aber keine die auftretenden Kräfte abtragende Verankerung darstellen, die Einbaulage der Randprofile festlegen läßt. Nachteilig bei bekannten Überbrückungsvorrichtungen der gattungsgemäßen Art ist allerdings, daß ihre Verwendung wegen ansonsten unzulässig hoher Beanspruchung auf Anwendungsfälle mit einem maximalen Arbeitsbereich von etwa 80mm beschränkt ist.Bridging devices, as used in particular on road bridges to compensate for the thermal expansion caused changes in the length of the superstructure, are known in different designs and in use. Differences are in particular bridging devices with lamellae, which are arranged within the joint gap between and parallel to the joint edges and are supported on the expansion joint bridging trusses, on the one hand and lamellar bridging devices on the other. Bridging devices with slats are particularly suitable for bridging expansion joints with a comparatively large working range (difference between maximum and minimum joint width). However, they are relatively expensive to produce, require a large installation space, and the installation is complicated and time-consuming. For this reason, it is endeavored to use bridging devices without lamellae, in which both the manufacture and the installation with less effort are connected. Bridging devices of the type specified in the introduction, as published, inter alia, in the - after the priority date of the present application published - company publication "single-celled joint type RE with Robo ® Flex" of Mageba SA, CH, are particularly attractive in terms of economy as well as the required installation space -Bülach are described. These bridging devices can be installed within a very short time, since the edge profiles are not mechanically anchored directly to the support structure of the superstructure or the abutment (ie in the case of execution of abutment and superstructure with a substructure and a road surface applied to the substructure) but instead Rather, they are anchored via their flat, strip-shaped holding sections in which the recesses of the abutment or superstructure filling polymer concrete. By "embedding" the - generally arranged in a substantially horizontal plane - holding sections of the edge profiles in the polymer concrete is to be understood that the holding sections dive into the polymer concrete at least a predominant proportion, so that at least above and below the holding sections polymer concrete is provided , However, this anchoring of the edge profiles on their embedded in the polymer concrete holding sections does not exclude that the edge profiles in addition may also be selectively mechanically supported directly on the respective support structure, which represent by means of appropriate mounting supports, but which do not represent the forces eroding anchoring, set the installation position of the edge profiles. A disadvantage of known bridging devices of the generic type, however, is that their use because otherwise Inadmissible high stress on applications with a maximum working range of about 80mm is limited.

Aufgabe der vorliegenden Erfindung ist es, eine sich durch einen besonders geringen Herstellungs- und Montageaufwand auszeichnende Überbrückungsvorrichtung der gattungsgemäßen Art bereitzustellen, mit der sich Dehnungsfugen mit einem größeren Arbeitsbereich überbrükken lassen, als dies mit herkömmlichen Überbrückungsvorrichtungen der gattungsgemäßen Art möglich ist.Object of the present invention is to provide a characterized by a particularly low manufacturing and assembly costs bridging device of the generic type, with the expansion joints can bridge with a larger work area, as is possible with conventional bridging devices of the generic type.

Gelöst wird diese Aufgabenstellung gemäß der vorliegenden Erfindung dadurch, daß mit jedem Randprofil an dessen Oberseite ein Zahnprofil verbunden ist, dessen Oberfläche im wesentlichen mit der Oberfläche des Polymerbetons und des zugeordneten Widerlagers bzw. Überbaus abschließt und dessen Zähne mit den Zähnen des jeweils anderen Zahnprofils kämmen. Die vorliegende Erfindung macht sich die Erkenntnis zunutze, daß sich durch die beiden mit den Randprofilen verbundenen, miteinander kämmenden Zahnprofile diejenigen dynamischen Belastungen, die beim Überfahren der Überbrückungsvorrichtung mit Kraftfahrzeugen auf die Randprofile wirken, substantiell reduzieren lassen verglichen mit gattungsgemäßen Überbrückungsvorrichtungen ohne derartige Zahnprofile. Dies gestattet es, mit besonders geringen Herstellungs- und Montageaufwand verbundene und nur minimalen Einbauraum benötigende Überbrückungsvorrichtungen der eingangs angegebenen Art ohne Überschreitung der zulässigen Belastungen der Randprofile durch dynamische Stöße auch in solchen Anwendungsfällen einzusetzen, in denen bisher infolge des erforderlichen Arbeitsbereichs auf aufwendigere Konstruktionen zurückgegriffen werden mußte. Beispielsweise lassen sich erfindungsgemäße Überbrückungsvorrichtungen auch an solchen Bauwerken einsetzen, bei denen der Arbeitsbereich der Dehnfuge bis 100mm oder sogar mehr beträgt. Dies erschließt der, wie dargelegt, in verschiedener Hinsicht äußerst attraktiven Überbrückungsvorrichtung der eingangs angegebenen Art erkennbar ganz neue Anwendungsmöglichkeiten.This object is achieved according to the present invention, characterized in that with each edge profile at the top of a tooth profile is connected, whose surface substantially terminates with the surface of the polymer concrete and the associated abutment or superstructure and mesh its teeth with the teeth of the other tooth profile , The present invention makes use of the knowledge that can be substantially reduced by the two interconnected with the edge profiles, meshing tooth profiles those dynamic loads that act when driving over the bridging device with motor vehicles on the edge profiles compared with generic bridging devices without such tooth profiles. This makes it possible to use with particularly low manufacturing and assembly costs associated and minimal installation space required bridging devices of the type specified without exceeding the allowable loads of the edge profiles by dynamic shocks in those applications where previously resorted to more expensive constructions due to the required work area had to become. For example, bridging devices according to the invention can also be used on structures in which the working range of the expansion joint is up to 100 mm or even more. This opens up, as explained, in many respects extremely attractive bridging device of the type specified recognizable entirely new applications.

Besonders interessant ist die vorliegende Erfindung auch im Hinblick auf die Umrüstung bestehender Bauwerke unter Ersatz herkömmlicher Überbrückungsvorrichtungen beliebiger Bauart durch solche nach der vorliegenden Erfindung. In diesem Zusammenhang kommt zum Tragen, daß die erfindungsgemäße Überbrückungsvorrichtung mit einem minimalen Einbauraum in der Höhe auskommt, so daß typischerweise - im Falle der Ausführung von Widerlager und Überbau mit einer Unterkonstruktion (insbesondere aus Konstruktionsbeton) und einem darauf aufgebrachten Fahrbahnbelag (insbesondere aus Asphalt) - die Dicke des Fahrbahnbelages für die Unterbringung der Überbrükkungsvorrichtung ausreicht. Dies bedeutet, daß sich bei einer solche Bauweise, auf die die vorliegende Erfindung freilich nicht beschränkt ist, die mit Polymerbeton zu verfüllende Aussparung im allgemeinen nicht in die Unterkonstruktion hinein erstrecken muß sondern sich auf die Höhe des Fahrbahnbelags beschränken kann. Ebenfalls gerade im Hinblick auf die Umrüstung bestehender Bauwerke interessant ist die extrem kurze Zeit, die für den Einbau der erfindungsgemäßen Überbrückungsvorrichtung benötigt wird, wozu maßgeblich beiträgt, daß es keiner direkten mechanischen Verankerung der Randprofile in der jeweiligen Tragkonstruktion des Widerlagers und des Überbaus bedarf. Die entsprechend kurze Einbauzeit für die erfindungsgemäße Überbrükkungsvorrichtung führt zu einer nur minimalen Dauer der Sperrung des entsprechenden Bauwerks während dessen Umrüstung.Particularly interesting is the present invention also with regard to the conversion of existing structures with replacement of conventional bridging devices of any type by those of the present invention. In this context, it comes into play that the bridging device according to the invention with a minimum installation space in height manages, so that typically - in the case of execution of abutment and superstructure with a substructure (in particular of structural concrete) and a road surface applied thereon (especially asphalt) - The thickness of the road surface for housing the Überbrükkungsvorrichtung sufficient. This means that in such a construction, to which the present invention is admittedly not limited, the recess to be filled with polymer concrete generally does not have to extend into the substructure but can be limited to the height of the road surface. Also of particular interest with regard to the conversion of existing structures is the extremely short time required for the installation of the bridging device according to the invention, which significantly contributes to the fact that it requires no direct mechanical anchoring of the edge profiles in the respective support structure of the abutment and the superstructure. The corresponding short installation time for the Überbrükkungsvorrichtung invention leads to a minimal duration of the blocking of the corresponding structure during its conversion.

Im Hinblick auf die vorstehenden Ausführungen ist es besonders günstig, daß die Randprofile der Überbrükkungsvorrichtung nicht lastabtragend mechanisch direkt in der Tragkonstruktion von Widerlager und Überbau verankert sind, sondern ihre (lastabtragende) Lagesicherung im Einbauzustand durch eine Verankerung der leistenförmigen Halteabschnitte der Randprofile in dem Polymerbeton erfolgt, der die Aussparungen in den an die Dehnfuge angrenzenden Bereichen von Widerlager und Überbau füllt. In diesem Zusammenhang ist darauf hinzuweisen, daß ein sich zwischen der Unterseite des Randprofils und dem Widerlager bzw. dem Überbau bis unter die Aussparung erstreckendes, insbesondere an dem Randprofil angeheftetes Abschalblech, welches den mit Polymerbeton zu verfüllenden Raum zur Fuge hin begrenzt, in diesem Sinne ebensowenig als eine (lastabtragende) Verankerung des entsprechenden Randprofils an der Tragkonstruktion zu verstehen ist wie eine zusätzliche punktuelle Abstützung der Randprofile an der jeweiligen Tragkonstruktion, um die Randprofile bei der Montage der Überbrückungsvorrichtung in ihrer Einbaulage zu halten (s.o.). Derartige Montageabstützungen sind im übrigen, um eine nennenswerte Lastabtragung im Betrieb auszuschließen, zweckmäßigerweise nachgiebig; beispielsweise können die genannten Montageabstützungen Federelemente umfassen.In view of the above, it is particularly advantageous that the edge profiles of the Überbrükkungsvorrichtung not mechanically anchored directly in the support structure of abutment and superstructure, but their (load-removing) position assurance in the installed state by anchoring the strip-shaped holding sections of the edge profiles in the polymer concrete which fills the recesses in the areas of abutment and superstructure adjoining the expansion joint. In this context, it should be noted that a between the underside of the edge profile and the abutment or the superstructure extending below the recess, in particular attached to the edge profile Abschalblech, which limits the space to be filled with polymer concrete to the joint, in this sense just as little as a (load-bearing) anchoring of the corresponding edge profile on the support structure is to be understood as an additional selective support of the edge profiles of the respective support structure to hold the edge profiles during assembly of the lock-up device in its installed position (see above). Incidentally, in order to rule out any significant load transfer during operation, such mounting supports are expediently yielding; For example, said mounting supports may comprise spring elements.

Im Hinblick auf eine besonders günstige Abtragung der Horizontal-, Vertikal- und Querkräfte, wie sie beim Überfahren der Überbrückungsvorrichtung durch Kraftfahrzeuge über die Zahnprofile in die Randprofile eingeleitet werden, ist es vorteilhaft, wenn die Breite der Aussparungen des Fahrbahnbelags zwischen dem 2,4-fachen und dem 4,0-fachen Wert des Arbeitsbereichs der Dehnfuge, besonders bevorzugt zwischen dem 2,8-fachen und dem 3,3-fachen Wert des Arbeitsbereichs der Dehnfuge beträgt.With regard to a particularly favorable removal of horizontal, vertical and lateral forces, as in the Driving over the bridging device by motor vehicles via the tooth profiles are introduced into the edge profiles, it is advantageous if the width of the recesses of the road surface between 2.4 times and 4.0 times the value of the working range of the expansion joint, particularly preferably between the 2 , 8 times and 3.3 times the working range of the expansion joint.

Gemäß einer anderen bevorzugten Weiterbildung der Erfindung ist vorgesehen, daß die Halteabschnitte der Randprofile mit Polymerbeton ausgefüllte Durchbrüche aufweisen. Die Fläche jener Durchbrüche beträgt dabei bevorzugt jeweils mindestens 120cm2, besonders bevorzugt mindestens 180 cm2. Durch solche Durchbrüche hindurch kann der Polymerbeton beim Einbau der erfindungsgemäßen Überbrückungsvorrichtung einfach und prozeßsicher in den unterhalb des jeweiligen Halteabschnitts liegenden Bereich der Aussparung eingefüllt werden. Hierdurch ist es möglich, daß sich die Halteabschnitte der Randprofile ohne nachteilige Auswirkungen auf ihre Einbettung in den Polymerbeton nahezu über die gesamte Breite der Aussparungen erstrecken können, was sich wiederum günstig auf die Abtragung der über die Zahnprofile in die Randprofile eingeleiteten Kräfte auswirkt. In diesem Sinne zeichnet sich eine bevorzugte Weiterbildung der Erfindung dadurch aus, daß die Breite der Randprofile samt deren Halteabschnitten mehr als den 0,8-fachen Wert der Breite der Aussparungen, besonders bevorzugt mehr als den 0,85-fachen Wert der Breite der Aussparungen beträgt.According to another preferred embodiment of the invention, it is provided that the holding sections of the edge profiles having polymer concrete filled openings. The area of those breakthroughs is preferably in each case at least 120 cm 2 , particularly preferably at least 180 cm 2 . Through such breakthroughs, the polymer concrete during installation of the bridging device according to the invention can be filled easily and reliably in the lying below the respective holding portion portion of the recess. This makes it possible that the holding portions of the edge profiles can extend without adverse effects on their embedding in the polymer concrete almost over the entire width of the recesses, which in turn has a favorable effect on the removal of the introduced via the tooth profiles in the edge profiles forces. In this sense, a preferred development of the invention is characterized in that the width of the edge profiles together with their holding sections more than 0.8 times the value of the width of the recesses, more preferably more than 0.85 times the value of the width of the recesses is.

Bevorzugt beträgt die Gesamtfläche der Durchbrüche jedes Halteabschnitts zwischen dem 0,8-fachen und 2,0-fachen Wert der Fläche (Länge x Breite) der Dehnfuge bei deren mittlerer Breite. Bei einer entsprechenden Bemessung der Durchbrüche ergeben sich besonders günstige Verhältnisse sowohl hinsichtlich der Einbettung der Halteabschnitte in den Polymerbeton als auch hinsichtlich der Lastabtragung. In diesem Zusammenhang spielt eine Rolle, daß das Durchdringen der Halteabschnitte mit Polymerbeton im Bereich der Durchbrüche auch im Hinblick auf eine gute Verankerung der Randprofile im Polymerbeton vorteilhaft ist.Preferably, the total area of the apertures of each holding portion is between 0.8 times and 2.0 times Value of the area (length x width) of the expansion joint at its mean width. With a corresponding dimensioning of the breakthroughs, particularly favorable conditions arise both with regard to the embedding of the holding sections in the polymer concrete and with regard to the load transfer. In this context, it plays a role that the penetration of the holding sections with polymer concrete in the area of the openings is also advantageous with regard to a good anchoring of the edge profiles in the polymer concrete.

Wenngleich die Formgebung der Durchbrüche keinen strengen Beschränkungen unterworfen ist, so ist es dennoch besonders vorteilhaft, wenn die Durchbrüche im wesentlichen rechteckig sind und ihre Erstreckung in Fugenlängsrichtung zwischen dem 1,4-fachen und dem 3,0-fachen Wert der Breite der zwischen jeweils zwei einander benachbarten Durchbrüchen verbliebenen Stege beträgt. Auch dies trägt wiederum zu besonders günstigen Verhältnissen beim Einbau der erfindungsgemäßen Überbrückungsvorrichtung sowie bei deren Nutzung bei. Zwingend ist eine solche rechteckige Formgebung der Durchbrüche indessen nicht. Vielmehr können diese auch kreisförmig, oval, elliptisch oder in sonstiger Weise ausgeführt sein.Although the shape of the apertures is not severely limited, it is still particularly advantageous if the apertures are substantially rectangular and their lengthwise extension is between 1.4 times and 3.0 times the width of each other two remaining adjacent openings breakthroughs is. This in turn also contributes to particularly favorable conditions when installing the bridging device according to the invention as well as during its use. However, such a rectangular shape of the openings is not mandatory. Rather, they can also be circular, oval, elliptical or otherwise executed.

Besonders bevorzugt sind die Zahnprofile mit den Randprofilen verschraubt. Dies erweist sich insbesondere im Hinblick auf eine rasche Montage der Überbrückungsvorrichtung als günstig. Denn über diejenigen Gewindebohrungen der Randprofile, in die später die der Befestigung der Zahnprofile dienenden Schrauben eingeschraubt werden, können zunächst Versetztraversen mit den Randprofilen verschraubt werden, welche auf die Fahrbahnbeläge des Überbaus und des Widerlagers außerhalb der Aussparungen aufgelegt werden, um die Randprofile in ihrer Einbaulage zu halten und zu nivellieren. Nach dem Abbinden des Polymerbetons werden die Schrauben gelöst, die Versetztraversen entfernt und die Zahnprofile an den Randprofilen eingeschraubt.Particularly preferably, the tooth profiles are screwed to the edge profiles. This proves to be favorable in particular with regard to a quick mounting of the bridging device. Because on those threaded holes of the edge profiles, in which later the attachment of the tooth profiles serving screws are screwed, can first be bolted spreaders with the edge profiles, which on the road surfaces of the superstructure and the abutment are placed outside of the recesses in order to keep the edge profiles in their installed position and to level. After setting the polymer concrete, the screws are loosened, the transfer spreaders removed and the tooth profiles screwed to the edge profiles.

Was die Formgebung der Zahnprofile angeht, so läßt die vorliegende Erfindung hier einen erheblichen Gestaltungsspielraum zu. Insbesondere kommen sinus-förmig ausgeführte Zahnprofile und zickzack-förmig ausgeführte Zahnprofile mit mehr oder weniger abgerundeten Spitzen in Betracht. Die jeweiligen Spitzen der Zähne können dabei leicht abgeschrägt sein. Die Zahnhöhe ist an den Arbeitsbereich der Dehnungsfugen angepaßt.As far as the shape of the tooth profiles is concerned, the present invention allows for considerable freedom of design. In particular, sinusoidal tooth profiles and zigzag-shaped tooth profiles with more or less rounded tips are possible. The respective tips of the teeth can be slightly bevelled. The tooth height is adapted to the working area of the expansion joints.

Die im Rahmen der vorliegenden Erfindung zum Einsatz kommenden Randprofile können einteilig ausgeführt sein. Besonders bevorzugt sind sie indessen aus mehreren Teilen zusammengefügt, insbesondere indem jedes der Randprofile eine Befestigungsleiste umfaßt, die mit einer den Halteabschnitt umfassenden Grundleiste verschweißt ist und an der das zugeordnete Zahnprofil befestigt ist. Diese Weiterbildung ist im Hinblick auf die Herstellungskosten für die Randprofile besonders vorteilhaft.The edge profiles used in the context of the present invention can be made in one piece. Most preferably, however, they are joined together from several parts, in particular by each of the edge profiles comprises a fastening strip which is welded to a base strip comprising the holding portion and to which the associated tooth profile is attached. This development is particularly advantageous with regard to the production costs for the edge profiles.

Gemäß einer anderen bevorzugten Weiterbildung der Erfindung ist das Dichtprofil als Höcker-Hohlprofil ausgeführt, wobei sich der Höcker in den seitlich durch die beiden Befestigungsleisten und oben durch die beiden Zahnprofile begrenzten Raum hinein erstreckt. Ein solches Dichtungsprofil (vgl. DE 29907832 U1 ) trägt insbesondere dem durch die vorliegende Erfindung möglichen großen Arbeitsbereich der Überbrückungsvorrichtung Rechnung. Es unterbindet im übrigen das Ansammeln von allzugroßen Mengen an Schmutz in dem Bereich oberhalb der Dichtung. Eine entsprechende Ausführung des Dichtprofils ist in gleicher Weise günstig bei einteiligen Randprofilen.According to another preferred embodiment of the invention, the sealing profile is designed as a bumped hollow profile, wherein the bump extends into the space bounded laterally by the two fastening strips and above by the two tooth profiles. Such a sealing profile (see. DE 29907832 U1 ) contributes in particular to the possible by the present invention large working area of the lock-up device bill. It also prevents the accumulation of excessive amounts of dirt in the area above the seal. A corresponding embodiment of the sealing profile is in the same way favorable for one-piece edge profiles.

Schließlich kann gemäß einer abermals anderen bevorzugten Weiterbildung der Erfindung vorgesehen sein, daß im Bereich des Übergangs vom Widerlager bzw. Überbau zum Polymerbeton im Bereich der Fahrbahnoberfläche jeweils eine Heißvergußfuge vorgesehen ist. Im Falle der Ausführung von Widerlager und Überbau mit einer Unterkonstruktion (insbesondere aus Konstruktionsbeton) und einem darauf aufgebrachten Fahrbahnbelag (insbesondere aus Asphalt) dichtet diese Heißvergußfuge den Übergang vom Fahrbahnbelag zum Polymerbeton ab.Finally, according to yet another preferred embodiment of the invention, it is provided that in each case a Heißvergußfuge is provided in the region of the transition from the abutment or superstructure to the polymer concrete in the region of the road surface. In the case of execution of abutment and superstructure with a substructure (in particular of structural concrete) and a road surface applied thereon (especially asphalt) this Heißvergußfuge seals the transition from the road surface to the polymer concrete.

Im folgenden wird die vorliegende Erfindung anhand eines in der Zeichnung veranschaulichten bevorzugten Ausführungsbeispiels naher erläutert. Dabei zeigt

In the following, the present invention will be explained in more detail with reference to a preferred embodiment illustrated in the drawing. It shows
Fig. 1
a vertical section through an inventively executed, built into a building Bridging device and
Fig. 2
a plan view of the lock-up device according to Fig. 1 (not mounted).

Die in der Zeichnung dargestellte Überbrückungsvorrichtung 1 dient der Überbrückung einer Dehnfuge 2, wie sie in einem befahrbaren Bauwerk wie insbesondere einer Brücke zwischen einem Widerlager 3 und einem Überbau 4 vorgesehen ist. Das Widerlager 3 umfaßt eine aus Konstruktionsbeton bestehende Unterkonstruktion 5 und einen darauf aufgebrachten, etwa 100mm starken Fahrbahnbelag 6 aus Asphalt, wobei zwischen der Unterkonstruktion 5 und dem Fahrbahnbelag 6 eine wasserundurchlässige Isolierung 7 angeordnet ist. In gleicher Weise ist der Überbau 4 ausgeführt.The bridging device 1 shown in the drawing serves to bridge an expansion joint 2, as provided in a navigable structure such as in particular a bridge between an abutment 3 and a superstructure 4. The abutment 3 comprises a structural concrete existing substructure 5 and a applied thereon, about 100mm thick road surface 6 asphalt, with a waterproof insulation 7 is disposed between the substructure 5 and the road surface 6. In the same way, the superstructure 4 is executed.

Angrenzend an die Dehnfuge 2 ist der Fahrbahnbelag 6 sowohl am Widerlager 3 als auch am Überbau 4 ausgespart, und zwar auf einer Breite von jeweils etwa 300mm. Auch die Isolierung 7 ist im Bereich der Aussparungen 8 weitgehend entfernt; ein schmaler Randbereich 9 der Isolierung 7 ist im Bereich der Aussparung 8 indessen stehengelassen, um eine Anbindung der Isolierung 7 an den Polymerbeton 10 bereitzustellen, mit dem die Aussparungen 8 verfüllt sind und dessen Oberfläche 11 mit der Oberfläche 12 des angrenzenden Fahrbahnbelags 6 bündig ist. Im Hinblick auf eine gute Verbindung des Polymerbetons 10 mit dem Konstruktionsbeton der Unterkonstruktion 5 ist die freigelegte Oberfläche des Konstruktionsbetons vor dem Vergießen des Polymerbetons 10 trocken und sandgestrahlt. Die mit dem Polymerbeton (z.B. "Roboflex Plus" der Fa. Mageba S.A., CH-Bülach) zu verfüllenden Bereiche werden zur Dehnfuge 2 hin jeweils durch ein Abschalblech 13 begrenzt, das an dem entsprechenden Randprofil 14 angeheftet ist.Adjacent to the expansion joint 2 of the road surface 6 is recessed both on the abutment 3 and on the superstructure 4, on a width of about 300mm. The insulation 7 is largely removed in the region of the recesses 8; a narrow edge region 9 of the insulation 7 is, however, left standing in the region of the recess 8 in order to provide a connection of the insulation 7 to the polymer concrete 10, with which the recesses 8 are filled and whose surface 11 is flush with the surface 12 of the adjacent road surface 6. In view of good bonding of the polymer concrete 10 to the structural concrete of the substructure 5, the exposed surface of the structural concrete is dry and sandblasted prior to casting the polymer concrete 10. The areas to be filled with the polymer concrete (for example "Roboflex Plus" from Mageba S.A., CH-Bülach) are delimited in each case by a scraping plate 13 attached to the expansion joint 2, which is attached to the corresponding edge profile 14.

In den Polymerbeton 10 ist jeweils ein leistenförmiger Halteabschnitt 16 eines metallischen Randprofils 14 eingebettet, welches aus zwei miteinander verschweißten Leisten, nämlich einer den Halteabschnitt 16 umfassenden Grundleiste 17 und einer mit dieser verschweißten Befestigungsleiste 18 zusammengefügt ist. Die Befestigungsleisten weisen Gewindebohrungen 19 auf, in die Befestigungsschrauben 20 eingeschraubt sind, welche der Befestigung jeweils eines Zahnprofils 21 an dem zugeordneten Randprofil 14 dienen. Die Oberflächen 22 der Zahnprofile 21 schließen mit den Oberflächen 11 bzw. 12 des Polymerbetons 10 und des zugeordneten Fahrbahnbelags 6 ab. Die Zahnhöhe beträgt etwa 100mm, woraus sich ein Arbeitsbereich der Überbrückungsvorrichtung 1 von etwa 100mm ergibt.In the polymer concrete 10 each a strip-shaped holding portion 16 of a metallic edge profile 14 is embedded, which is composed of two strips welded together, namely a holding portion 16 comprehensive base strip 17 and a welded thereto fastening bar 18. The fastening strips have threaded holes 19, are screwed into the fastening screws 20, which the Attaching a respective toothed profile 21 serve on the associated edge profile 14. The surfaces 22 of the tooth profiles 21 terminate with the surfaces 11 and 12 of the polymer concrete 10 and the associated roadway covering 6. The tooth height is about 100mm, resulting in a working range of the lock-up device 1 of about 100mm.

Die Halteabschnitte 16 der Randprofile 14, die bis auf einen geringen Spalt 23 an die die Aussparungen 8 begrenzenden Kanten 24 heranreichen, weisen mit Polymerbeton 10 ausgefüllte Durchbrüche 25 auf. Diese sind im wesentlichen rechteckig und etwa 170mm lang (in Fugenlängsrichtung) und etwa 140mm breit (quer zur Fugenlängsrichtung). Die Breite der zwischen jeweils zwei einander benachbarten Durchbrüchen 25 verbliebenen Stege 26 beträgt etwa 80mm. Eine direkte Verankerung der Randprofile 14 in der Unterkonstruktion 3 liegt nicht vor.The holding portions 16 of the edge profiles 14, which extend to a small gap 23 to the edges 8 bounding the edges 24, have filled with polymer concrete 10 openings 25. These are essentially rectangular and about 170mm long (in the longitudinal direction of the joint) and about 140mm wide (transverse to the joint longitudinal direction). The width of the remaining between each two adjacent openings 25 webs 26 is about 80mm. A direct anchoring of the edge profiles 14 in the substructure 3 is not available.

Zwischen den beiden Randprofilen 14 erstreckt sich ein elastisches Dichtprofil 27. Dieses ist dichtend an die beiden Randprofile 14 angeschlossen, indem jeder der beiden Ränder 28 des Dichtprofils 27 in eine Nut 29 des entsprechenden Randprofils 14 eingeknöpft ist. Das Dichtprofil 27 ist als Höcker-Hohlprofil ausgeführt, wobei sich der Höcker 30 in den seitlich durch die beiden Befestigungsleisten 18 und oben durch die beiden Zahnprofile 21 begrenzten Raum hinein erstreckt.This is sealingly connected to the two edge profiles 14 by each of the two edges 28 of the sealing profile 27 is buttoned into a groove 29 of the corresponding edge profile 14 between the two edge profiles 14. The sealing profile 27 is designed as a bump-shaped hollow profile, wherein the bump 30 extends into the space laterally delimited by the two fastening strips 18 and above by the two tooth profiles 21.

Im Falle eines anderen, von dem vorstehend beschriebenen Ausführungsbeispiel abweichenden Aufbaus von Widerlager und Überbau, insbesondere indem diese vollständig aus Beton, der auch die Fahrbahnoberfläche bildet, bestehen, gelten die vorstehenden Erläuterungen in entsprechend abgewandelter Weise. Im übrigen sind im Rahmen der vorliegenden Erfindung ersichtlich verschiedene fachmännische Abwandlungen möglich, ohne das in den Ansprüchen zu Ausdruck gebrachte Prinzip zu verlassen, beispielsweise indem die die Ausschnitte begrenzenden Kanten in Widerlager und Überbau schräg und/oder profiliert ausgeführt sind, namentlich zur Bildung von mit Polymerbeton auszufüllenden Hinterschneidungen.In the case of another structure of abutment and superstructure deviating from the above-described embodiment, in particular in that they consist entirely of concrete, which also forms the road surface, apply the above explanations in a correspondingly modified manner. Incidentally, in the context of the present invention, various expert modifications are possible without departing from the principle expressed in the claims, for example by the edges limiting the cutouts in abutment and superstructure are made oblique and / or profiled, especially for the formation of Polymer concrete to be filled undercuts.
