Description

ÜberbrückungsVorrichtung bridging device
Die vorliegende Erfindung betrifft eine Überbrückungs- Vorrichtung für eine zwischen einem Widerlager und ei¬ nem Überbau angeordnete Dehnfuge in einem befahrbaren Bauwerk, wobei das Widerlager und der Überbau angren¬ zend an die Dehnfuge Aussparungen aufweisen, die mit Polymerbeton verfüllt sind, in den jeweils ein flacher, leistenförmiger Halteabschnitt eines metallischen Rand¬ profils eingebettet ist, und sich zwischen den beiden Randprofilen ein elastisches Dichtprofil erstreckt, welches dichtend an die beiden Randprofile angeschlos¬ sen ist .The present invention relates to a bridging device for an expansion joint arranged between an abutment and a superstructure in a drivable structure, wherein the abutment and the superstructure adjoining the expansion joint have recesses which are filled with polymer concrete in each case flat, strip-shaped holding portion of a metallic Rand¬ profile is embedded, and extends between the two edge profiles an elastic sealing profile which is dichtlos connected to the two edge profiles.
Überbrückungsvorrichtungen, wie sie insbesondere an Straßenbrücken zum Einsatz kommen, um die durch Wärme¬ dehnungen verursachten Änderungen der Länge des Über¬ baus zu kompensieren, sind in unterschiedlichen Ausfüh¬ rungen bekannt und im Einsatz. Unterschieden werden dabei insbesondere Überbrückungsvorrichtungen mit La¬ mellen, 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 über¬ brücken. Sie sind indessen relativ teuer in der Her¬ stellung, 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 Her¬ stellung als auch der Einbau mit geringerem AufwandBridging devices, as used in particular on road bridges, in order to compensate for the changes in the length of the superstructure caused by thermal expansions, are known and used in different embodiments. Differences are in particular bridging devices with La¬, 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 slat-free 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 manufacture, require a large installation space, and also 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
BESTÄTΪGUNGSKOPΪE verbunden sind. Besonders attraktiv unter Gesichtspunk¬ ten sowohl der Wirtschaftlichkeit als auch des benötig¬ ten Einbauraumes sind dabei Überbrückungsvorrichtungen der eingangs angegebenen Art, wie sie u.a. in der - nach dem Prioritätstag der vorliegenden Anmeldung ver¬ öffentlichten - Firmenschrift "Einzellige Fuge Typ RE mit Robo®Flex" der Mageba SA, CH-Bülach beschrieben sind. Diese Überbrückungsvorrichtungen lassen sich in¬ nerhalb 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 Über¬ bau mit einer Unterkonstruktion und einem darauf aufge¬ brachten Fahrbahnbelag an der Unterkonstruktion) son¬ dern vielmehr über ihre flachen, leistenförmigen Halte¬ abschnitte 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 überwiegen¬ den Anteil in den Polymerbeton eintauchen, so daß zu¬ mindest über und unter den Halteabschnitten Polymer¬ beton vorgesehen ist. Diese Verankerung der Randprofile über deren in den Polymerbeton eingebetteten Halteab¬ schnitte schließt allerdings nicht aus, daß die Rand¬ profile im Einzelfall ergänzend auch punktuell mecha¬ nisch direkt an der jeweiligen Tragkonstruktion abge¬ stützt sein können, wobei sich mittels entsprechender Montageabstutzungen, welche aber keine die auftretenden Kräfte abtragende Verankerung darstellen, die Einbaula¬ ge der Randprofile festlegen läßt. Nachteilig bei be¬ kannten 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.BESTÄTΪGUNGSKOPΪE are connected. Bridging devices of the type specified at the outset, such as those described, inter alia, in the publication published after the priority date of the present application, are particularly attractive from the point of view of economy as well as the required installation space "single-celled joint type RE with Robo® Flex "Mageba SA, CH-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 supporting structure of the superstructure or abutment via corresponding anchors (ie in the case of abutment and superstructure with a substructure and a substructure applied thereto Road surface on the substructure) son¬ but rather on their flat, strip-shaped Halte¬ sections in which the recesses of the abutment or the superstructure filling polymer concrete are anchored. 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 at least a predominant proportion in the polymer concrete, so that at least over and under the holding sections polymer concrete is provided. However, this anchoring of the edge profiles over their embedded in the polymer concrete Halteab¬ sections does not exclude that the Rand¬ profiles in a particular case in addition selectively punctually mecha¬ nisch directly on the respective support structure can be ab¬ supported, which by means of appropriate Montageabstutzungen, but which do not represent the forces eroding anchoring, the Einbaula¬ ge determine the edge profiles. A disadvantage of be¬ known bridging devices of the generic type, however, is that their use due to 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 Monta¬ geaufwand auszeichnende Überbrückungsvorrichtung der gattungsgemäßen Art bereitzustellen, mit der sich Deh¬ nungsfugen mit einem größeren Arbeitsbereich überbrük- ken lassen, als dies mit herkömmlichen Überbrückungs- vorrichtungen der gattungsgemäßen Art möglich ist.The object of the present invention is to provide a bridging device of the generic type which is distinguished by a particularly low manufacturing and assembly effort, with which expansion joints can be bridged over a larger working range than with conventional bridging devices of the generic type Art is possible.
Gelöst wird diese Aufgabenstellung gemäß der vorliegen¬ den Erfindung dadurch, daß mit jedem Randprofil an des¬ sen Oberseite ein Zahnprofil verbunden ist, dessen Oberfläche im wesentlichen mit der Oberfläche des Poly¬ merbetons und des zugeordneten Widerlagers bzw. Über¬ baus 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, mit¬ einander kämmenden Zahnprofile diejenigen dynamischen Belastungen, die beim Überfahren der Überbrückungsvor¬ richtung mit Kraftfahrzeugen auf die Randprofile wir¬ ken, substantiell reduzieren lassen verglichen mit gattungsgemäßen Überbrückungsvorrichtungen ohne derar¬ tige Zahnprofile. Dies gestattet es, mit besonders ge¬ ringen Herstellungs- und Montageaufwand verbundene und nur minimalen Einbauraum benötigende Überbrückungsvor¬ richtungen der eingangs angegebenen Art ohne Über¬ schreitung der zulässigen Belastungen der Randprofile durch dynamische Stöße auch in solchen Anwendungsfällen einzusetzen, in denen bisher infolge des erforderlichen Arbeitsbereichs auf aufwendigere Konstruktionen zurück- gegriffen werden mußte. Beispielsweise lassen sich er¬ findungsgemäße Überbrückungsvorrichtungen auch an sol¬ chen Bauwerken einsetzen, bei denen der Arbeitsbereich der Dehnfuge bis 100mm oder sogar mehr beträgt. Dies erschließt der, wie dargelegt, in verschiedener Hin¬ sicht äußerst attraktiven Überbrückungsvorrichtung der eingangs angegebenen Art erkennbar ganz neue Anwen¬ dungsmöglichkeiten.This problem is solved in accordance with the present invention in that a tooth profile is connected to each edge profile on its upper side, the surface of which essentially closes with the surface of the polymer clay and the associated abutment or superstructure and its teeth Comb with the teeth of the other tooth profile. The present invention makes use of the finding that the two tooth profiles which mesh with the edge profiles and which mesh with one another substantially reduce those dynamic loads which are exerted on the edge profiles when driving over the bridging device with motor vehicles compared to the generic ones Bridging devices without derar¬ tige tooth profiles. This makes it possible to use bridging devices of the type specified at the beginning, which require particularly low manufacturing and assembly costs and without exceeding the permissible loads on the edge profiles by dynamic shocks, even in those applications in which hitherto, as a result of the required Work area to more complex constructions. had to be seized. For example, bridging devices according to the invention can also be used on such structures in which the working range of the expansion joint is up to 100 mm or even more. As can be seen, this opens up completely new possibilities of application, as shown in various respects, with an extremely attractive bridging device of the type specified at the outset.
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 typi¬ scherweise - 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 Überbrük- kungsvorrichtung ausreicht. Dies bedeutet, daß sich bei einer solche Bauweise, auf die die vorliegende Erfin¬ dung freilich nicht beschränkt ist, die mit Polymerbe¬ ton 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 beste¬ hender Bauwerke interessant ist die extrem kurze Zeit, die für den Einbau der erfindungsgemäßen Überbrückungs¬ vorrichtung benötigt wird, wozu maßgeblich beiträgt, daß es keiner direkten mechanischen Verankerung der Randprofile in der jeweiligen Tragkonstruktion des Wi¬ derlagers und des Überbaus bedarf. Die entsprechend kurze Einbauzeit für die erfindungsgemäße Überbrük- kungsvorrichtung 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 typi¬ cally - in the case of the execution of abutment and superstructure with a substructure (in particular of structural concrete) and a road surface applied thereon (in particular Asphalt) - the thickness of the road surface is sufficient to accommodate the bridging device. This means that in such a construction, to which the present invention is admittedly not limited, the recess to be filled with polymer clay generally does not have to extend into the substructure but may be limited to the height of the road surface. Also of particular interest with regard to the retrofitting of existing structures is the extremely short time required for the installation of the bridging device according to the invention, which contributes significantly to the fact that there is no direct mechanical anchoring of the edge profiles in the respective supporting structure of the bearing and the superstructure needs. The corresponding Short installation time for the bridging device according to the 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 Überbrük- kungsvorrichtung nicht lastabtragend mechanisch direkt in der Tragkonstruktion von Widerlager und Überbau ver¬ ankert sind, sondern ihre (lastabtragende) Lagesiche¬ rung 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 hinzu¬ weisen, daß ein sich zwischen der Unterseite des Rand¬ profils und dem Widerlager bzw. dem Überbau bis unter die Aussparung erstreckendes, insbesondere an dem Rand¬ profil angeheftetes Abschalblech, welches den mit Poly¬ merbeton zu verfüllenden Raum zur Fuge hin begrenzt, in diesem Sinne ebensowenig als eine (lastabtragende) Ver¬ ankerung des entsprechenden Randprofils an der Tragkon¬ struktion 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; bei¬ spielsweise können die genannten Montageabstützungen Federelemente umfassen.In view of the above, it is particularly favorable that the edge profiles of the bridging device are not mechanically anchored directly in the load-bearing structure of abutment and superstructure, but rather their load-bearing position securing in the installed state by anchoring the strip-shaped holding sections the edge profiles in the polymer concrete takes place, which fills the recesses in the areas adjacent the expansion joint areas of the abutment and superstructure. In this connection, it should be pointed out that a scarf plate extending between the underside of the edge profile and the abutment or the superstructure extending below the recess, in particular attached to the edge profile, encloses the space to be filled with polymer concrete limited to the joint, in this sense, as a (load-removing) Ver¬ anchoring of the corresponding edge profile of the Tragkon¬ construction is to understand as an additional selective support of the edge profiles of the respective support structure to the edge profiles during assembly of the lock-up device in their To keep mounting position (see above). Incidentally, in order to rule out any significant load transfer during operation, such mounting supports are expediently yielding; spielsweise, 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 Kraft¬ fahrzeuge über die Zahnprofile in die Randprofile ein¬ geleitet 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 Dehnfu¬ ge 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 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 area of the expansion joint, especially preferably between 2.8 times and 3, 3 times the value of the working range of the expansion joints.
Gemäß einer anderen bevorzugten Weiterbildung der Er¬ findung ist vorgesehen, daß die Halteabschnitte der Randprofile mit Polymerbeton ausgefüllte Durchbrüche aufweisen. Die Fläche jener Durchbrüche beträgt dabei bevorzugt jeweils mindestens 120cm2, besonders bevor¬ zugt mindestens 180 cm2. Durch solche Durchbrüche hin¬ durch kann der Polymerbeton beim Einbau der erfindungs- gemäßen Überbrückungsvorrichtung einfach und proze߬ sicher 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 Zahn¬ profile in die Randprofile eingeleiteten Kräfte aus¬ wirkt. 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, beson¬ ders bevorzugt mehr als den 0,85-fachen Wert der Breite der Aussparungen beträgt.According to another preferred development of the invention, it is provided that the holding sections of the edge profiles have apertures filled with polymer concrete. The area of those breakthroughs is preferably in each case at least 120 cm 2 , particularly preferably at least 180 cm 2 . Through such openings, the polymer concrete can be easily and safely filled into the region of the recess below the respective holding section when the bridging device according to the invention is installed. This makes it possible that the holding sections 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 aus¬ aus¬ on the removal of the profile on the Zahn¬ in the edge profiles initiated forces acts. 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 preferably more than 0.85 times the value of the width the recesses is.
Bevorzugt beträgt die Gesamtfläche der Durchbrüche je¬ des 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 gün¬ stige Verhältnisse sowohl hinsichtlich der Einbettung der Halteabschnitte in den Polymerbeton als auch hin¬ sichtlich der Lastabtragung. In diesem Zusammenhang spielt eine Rolle, daß das Durchdringen der Halteab¬ schnitte mit Polymerbeton im Bereich der Durchbrüche auch im Hinblick auf eine gute Verankerung der Randpro¬ file im Polymerbeton vorteilhaft ist .The total area of the openings of each holding section is preferably between 0.8 times and 2.0 times. times the value of the area (length x width) of the expansion joint at its average width. With a corresponding dimensioning of the openings, particularly favorable conditions arise both with regard to the embedding of the holding sections in the polymer concrete and with respect to the load transfer. In this context, it plays a role that the penetration of the holding sections with polymer concrete in the region of the openings is also advantageous with regard to a good anchoring of the edge profile in the polymer concrete.
Wenngleich die Formgebung der Durchbrüche keinen stren¬ gen Beschränkungen unterworfen ist, so ist es dennoch besonders vorteilhaft, wenn die Durchbrüche im wesent¬ lichen rechteckig sind und ihre Erstreckung in Fugen¬ längsrichtung zwischen dem 1,4-fachen und dem 3,0- fachen Wert der Breite der zwischen jeweils zwei einan¬ der benachbarten Durchbrüchen verbliebenen Stege be¬ trägt . Auch dies trägt wiederum zu besonders günstigen Verhältnissen beim Einbau der erfindungsgemäßen Über- brückungsvorrichtung sowie bei deren Nutzung bei. Zwin¬ gend ist eine solche rechteckige Formgebung der Durch¬ brüche indessen nicht. Vielmehr können diese auch kreisförmig, oval, elliptisch oder in sonstiger Weise ausgeführt sein.Although the shape of the apertures is not subject to strict restrictions, it is nevertheless particularly advantageous if the apertures are essentially rectangular and their extent in the longitudinal direction of the joint is between 1.4 times and 3.0 times Value of the width of the webs remaining between in each case two adjacent openings. This in turn also contributes to particularly favorable conditions when installing the bridging device according to the invention and during its use. However, such a rectangular shape of the apertures is not zwin¬ ing. Rather, they can also be circular, oval, elliptical or otherwise executed.
Besonders bevorzugt sind die Zahnprofile mit den Rand¬ profilen verschraubt. Dies erweist sich insbesondere im Hinblick auf eine rasche Montage der Überbrückungsvor- richtung als günstig. Denn über diejenigen Gewindeboh¬ rungen der Randprofile, in die später die der Befesti¬ gung der Zahnprofile dienenden Schrauben eingeschraubt werden, können zunächst Versetztraversen mit den Rand¬ profilen verschraubt werden, welche auf die Fahrbahnbe- läge 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. For it is first possible to screw connecting traverses to the edge profiles via those threaded bores of the edge profiles into which the screws serving to fasten the tooth profiles are subsequently screwed in, which are applied to the road surface. The superstructure and the abutment can be 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 Gestal¬ tungsspielraum 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 shaping of the tooth profiles is concerned, the present invention permits considerable freedom of design here. 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 Tei¬ len zusammengefügt, insbesondere indem jedes der Rand¬ profile 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 Her¬ stellungskosten für die Randprofile besonders vorteil¬ haft.The edge profiles used in the context of the present invention can be made in one piece. In the meantime, however, they are in particular made up of several parts, in particular in that each of the edge profiles comprises a fastening strip which is welded to a base strip comprising the holding section and to which the associated tooth profile is fastened. This development is particularly advantageous with regard to the production costs for the edge profiles.
Gemäß einer anderen bevorzugten Weiterbildung der Er¬ findung ist das Dichtprofil als Höcker-Hohlprofil aus¬ geführt, wobei sich der Höcker in den seitlich durch die beiden Befestigungsleisten und oben durch die bei¬ den Zahnprofile begrenzten Raum hinein erstreckt . Ein solches Dichtungsprofil (vgl. DE 29907832 Ul) trägt insbesondere dem durch die vorliegende Erfindung mögli- chen 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 Dicht- profus ist in gleicher Weise günstig bei einteiligen Randprofilen.According to another preferred development of the invention, the sealing profile is designed as a bumped hollow profile, with the bump extending into the space bounded laterally by the two fastening strips and at the top by the two tooth profiles. Such a sealing profile (see DE 29907832 Ul) contributes in particular to the possible by the present invention large working area of the bridging device. It also prevents the accumulation of excessive amounts of dirt in the area above the seal. A corresponding embodiment of the sealing profiled is in the same way favorable for one-piece edge profiles.
Schließlich kann gemäß einer abermals anderen bevorzug¬ ten 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 Aus¬ führung von Widerlager und Überbau mit einer Unterkon¬ struktion (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 development of the invention, it can be provided that in the area of the transition from the abutment or superstructure to the polymer concrete in the region of the roadway surface a hot grout joint is provided in each case. In the case of the execution of abutment and superstructure with a Unterkon¬ construction (in particular of structural concrete) and a road surface applied thereto (in particular asphalt) this Heißvergußfuge seals the transition from the road surface to the polymer concrete.
Im folgenden wird die vorliegende Erfindung anhand ei¬ nes in der Zeichnung veranschaulichten bevorzugten Aus¬ führungsbeispiels naher erläutert. Dabei zeigtIn the following, the present invention will be explained in more detail with reference to a preferred exemplary embodiment illustrated in the drawing. It shows
Fig. 1 einen Vertikalschnitt durch eine erfindungsgemäß ausgeführte, in ein Bauwerk eingebaute Überbrük- kungsvorrichtung und1 shows a vertical section through an inventively executed, built into a building Bridging kung device and
Fig. 2 eine Draufsicht auf die Überbrückungsvorrichtung nach Fig. 1 (nicht montiert) .Fig. 2 is a plan view of the lock-up device according to Fig. 1 (not mounted).
Die in der Zeichnung dargestellte Überbrückungsvorrich¬ tung 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 Kon¬ struktionsbeton bestehende Unterkonstruktion 5 und ei- nen darauf aufgebrachten, etwa 100mm starken Fahrbahn¬ belag 6 aus Asphalt, wobei zwischen der Unterkonstruk¬ tion 5 und dem Fahrbahnbelag S eine wasserundurchläs¬ sige Isolierung 7 angeordnet ist. In gleicher Weise ist der Überbau 4 ausgeführt.The Überbrückungsvorrich¬ shown in the drawing device 1 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 substructure 5 consisting of structural concrete and a NEN applied thereon, about 100mm strong Fahrbahn¬ covering 6 made of asphalt, between the Unterkonstruk¬ tion 5 and the road surface S a wasserundurchläs¬ sige insulation 7 is arranged. 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 ausge¬ spart, und zwar auf einer Breite von jeweils etwa 300mm. Auch die Isolierung 7 ist im Bereich der Ausspa¬ rungen 8 weitgehend entfernt; ein schmaler Randbereich 9 der Isolierung 7 ist im Bereich der Aussparung 8 in¬ dessen 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 Unter¬ konstruktion 5 ist die freigelegte Oberfläche des Kon¬ struktionsbetons 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 je¬ weils durch ein Abschalblech 13 begrenzt, das an dem entsprechenden Randprofil 14 angeheftet ist .Adjacent to the expansion joint 2, the road surface 6 is aus¬ both on the abutment 3 and on the superstructure 4 saves, on a width of about 300mm. The insulation 7 is also largely removed in the region of the recesses 8; a narrow edge region 9 of the insulation 7 is allowed to stand 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 is. With regard to a good connection of the polymer concrete 10 with the structural concrete of the substructure 5, the exposed surface of the structural concrete is dry and sandblasted prior to the casting of the polymer concrete 10. The areas to be filled with the polymer concrete (for example "Roboflex Plus" of the company Mageba S.A., CH-Bülach) are each limited to the expansion joint 2 by a scraping plate 13, 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 umfassen¬ den Grundleiste 17 und einer mit dieser verschweißten Befestigungsleiste 18 zusammengefügt ist. Die Befesti¬ gungsleisten weisen Gewindebohrungen 19 auf, in die Befestigungsschrauben 20 eingeschraubt sind, welche der Befestigung jeweils eines Zahnprofils 21 an dem zuge¬ ordneten Randprofil 14 dienen. Die Oberflächen 22 der Zahnprofile 21 schließen mit den Oberflächen 11 bzw. 12 des Polymerbetons 10 und des zugeordneten Fahrbahnbe¬ lags 6 ab. Die Zahnhöhe beträgt etwa 100mm, woraus sich ein Arbeitsbereich der ÜberbrückungsVorrichtung 1 von etwa 100mm ergibt.In the polymer concrete 10, a strip-shaped holding portion 16 of a metallic edge profile 14 is embedded in each case, which is composed of two strips welded together, namely the base strip 17 enclosing the holding section 16 and a fastening strip 18 welded thereto. The fastening strips have threaded bores 19, into which fastening screws 20 are screwed, which are the Attaching each of a tooth profile 21 on the zuge¬ arranged edge profile 14 serve. The surfaces 22 of the tooth profiles 21 terminate with the surfaces 11 and 12 of the polymer concrete 10 and the associated Fahrbahnbe¬ lags 6 from. The tooth height is about 100mm, resulting in a working range of the bridging device 1 of about 100mm.
Die Halteabschnitte 16 der Randprofile 14, die bis auf einen geringen Spalt 23 an die die Aussparungen 8 be¬ grenzenden Kanten 24 heranreichen, weisen mit Polymer¬ beton 10 ausgefüllte Durchbrüche 25 auf. Diese sind im wesentlichen rechteckig und etwa 170mm lang (in Fugen¬ längsrichtung) und etwa 140mm breit (quer zur Fugen¬ längsrichtung) . Die Breite der zwischen jeweils zwei einander benachbarten Durchbrüchen 25 verbliebenen Ste¬ ge 26 beträgt etwa 80mm. Eine direkte Verankerung der Randprofile 14 in der Unterkonstruktion 3 liegt nicht vor.The holding sections 16 of the edge profiles 14, which extend up to a small gap 23 to the edges 24 delimiting the recesses 8, have apertures 25 filled with polymer concrete 10. These are substantially rectangular and about 170mm long (in Fugen¬ longitudinal direction) and about 140mm wide (transverse to Fugen¬ longitudinal direction). The width of the remaining between each two adjacent apertures 25 Ste¬ ge 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 bei¬ den 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 bumped hollow profile, with the bump 30 extending into the space bounded laterally by the two fastening strips 18 and above by the two tooth profiles 21.
Im Falle eines anderen, von dem vorstehend beschriebe¬ nen Ausführungsbeispiel abweichenden Aufbaus von Wider¬ lager und Überbau, insbesondere indem diese vollständig aus Beton, der auch die Fahrbahnoberfläche bildet, be- stehen, gelten die vorstehenden Erläuterungen in ent¬ sprechend abgewandelter Weise. Im übrigen sind im Rah¬ men 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 profi¬ liert ausgeführt sind, namentlich zur Bildung von mit Polymerbeton auszufüllenden Hinterschneidungen. In the case of another structure of abutment and superstructure deviating from the embodiment described above, in particular in that it consists entirely of concrete, which also forms the roadway surface. the above explanations apply in a correspondingly modified manner. Moreover, within the scope of the present invention, it is apparent that various modifications are possible without departing from the principle expressed in the claims, for example by the edges delimiting the cutouts in the abutment and superstructure being oblique and / or profiled, namely for the formation of undercuts to be filled with polymer concrete.
