Abstract

The assembly for bridging over expansion joints comprises sealing band of elastic material which bridges over the joint, which sealing band, for being secured in upward open cavities, includes thickenings substantially filling up said cavities and extending in joint edge profiles at both sides in the longitudinal direction of the profile. Said thickenings include a support surface engaging in the inserted position with an appropriate pressing surface of the joint edge profile, said thickening being wedged in the cavity by means of a bulge formed thereon. Said thickening includes a nose formed thereon, which in the inserted position is pressed together in a manner that in the marginal portions of the cavity between the thickening and the joint edge profile there is a contact pressure. Thus it can be avoided that under the effect of any forces there opens a slit between the sealing band and the joint edge profile, whereinto moisture or dirt may make their way.

Description

Die Erfindung betrifft eine Vorrichtung zur Überbrückung von Dehnungsfugen, insbesondere in Brücken, Fahrbahnteilen oder dergleichen gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for bridging expansion joints, in particular in bridges, roadway parts or the like, according to the preamble of patent claim 1.

Eine Vorrichtung dieser Art ist aus der deutschen Patentschrift 28 08 386 bekannt. Wenn bei dieser bekannten Vorrichtung, die einen nicht befahrbaren Dichtungsprofilstreifen aufweist und daher nur für sehr schmale Fugen anwendbar ist, eine größere Zugbeanspruchung oder ein einseitiger Vertikalschub auftritt, kann sich zwischen dem Fugenrandprofil und dem darin aufgenommenen Dichtungsband ein Spalt öffnen, in den Feuchtigkeit und Schmutz eindringen kann. Dies führt auf die Dauer zu einer Beschädigung des Dichtungsbandes, wobei auch das Fugenrandprofil durch Korrosion in Mitleidenschaft gezogen werden kann.A device of this type is known from German patent 28 08 386. If this known device, which has a non-accessible sealing profile strip and therefore can only be used for very narrow joints, a greater tensile stress or a one-sided vertical thrust occurs, a gap can open between the joint edge profile and the sealing tape received therein, in the moisture and dirt can penetrate. In the long run, this leads to damage to the sealing tape, and the joint edge profile can also be affected by corrosion.

Auch bei der aus der deutschen Patentschrift 31 31 804 bekannten Überbrückungsvorrichtung, die einen befahrbaren Dichtungsprofilstreifen aufweist, ist das Eintreten von Feuchtigkeit und Schmutz in den Hohlraum des Fugenrandes nicht mit Sicherheit vermieden.In the bridging device known from German patent 31 31 804, which has a sealable strip that can be driven over, the entry of moisture and dirt into the cavity of the joint edge is not avoided with certainty.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Überbrückung von Dehnungsfugen der eingangs genannten Art so zu verbessern, daß auch bei erheblicher Zugbeanspruchung und bei einseitigem Vertikalschub das Eindringen von Schmutz und Feuchtigkeit in den Hohlraum des Fugenrandes mit Sicherheit vermieden ist, so daß die Nutzungsdauer dieser Vorrichtung erheblich verlängert wird.The invention has for its object to improve a device for bridging expansion joints of the type mentioned so that the penetration of dirt and moisture into the cavity of the joint edge is avoided with certainty, even with considerable tensile stress and one-sided vertical thrust, so that the service life this device is significantly extended.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöstThis object is achieved by the features specified in the characterizing part of patent claim 1

Bei der erfindungsgemäßen Fugenüberbrückungsvorrichtung wird nicht nur die an beiden Seiten des Dichtungsbandes Jeweils ausgebildete Verdickung in dem Hohlraum des Fugenrandes verkeilt, so daß das Dichtungsband sicher in den Fugenrändem gehalten ist, sondern es wird in den Randbereichen des Hohlraumes eine Vorspannung in dem dort anliegenden Dichtungsband erzeugt. Dazu wird eine vorspringende Nase, die an der Verdickung des Dichtungsbandes angeformt ist, in Einbaulage zusammengedrückt, woraus der Anpreßdruck resultierr, der ein sich Lösen des Dichtungsbandes von der Innenwand des Hohlraumes im Bereich der Randabschnitte verhindert. Die Größe der Vorspannung läßt sich dabei durch Wahl einer geeigneten Neigung der zusammenzudrückenden Nase so festlegen, daß die in der Praxis auftretenden in Fugenrichtung wirkenden Zugkräfte und senkrecht hierzu einwirkenden Vertikalkräfte kleiner als die Vorspannung des im Hohlraum angeordneten Dichtungsbandes sind.In the joint bridging device according to the invention, not only is the thickening formed on both sides of the sealing tape wedged in the cavity of the joint edge so that the sealing tape is securely held in the joint edges, but a pretension is generated in the edge area of the cavity in the sealing tape applied there . For this purpose, a projecting nose, which is formed on the thickening of the sealing tape, is compressed in the installed position, which results in the contact pressure which prevents the sealing tape from coming loose from the inner wall of the cavity in the region of the edge sections. The size of the pretension can be determined by choosing a suitable inclination of the nose to be compressed so that the tensile forces acting in the direction of the joint and the vertical forces acting perpendicularly to it in practice are smaller than the pretension of the sealing tape arranged in the cavity.

Zweckmäßigerweise ist die vorspringende Nase in einem Bereich angeformt; der an einem Randabschnitt des Hohlraums anliegt. Durch diese Maßnahme ist sichergestell daß an beiden Randabschnitten des Hohlraumes der gewünschte Anpreßdruck besteht, so daß jegliches Eindringen von Schmutz und Feuchtigkeit in den Hohlraum mit Sicherheit vermieden istThe projecting nose is expediently formed in one area; which abuts an edge portion of the cavity. This measure ensures that the desired contact pressure exists on both edge sections of the cavity, so that any penetration of dirt and moisture into the cavity is reliably avoided

Mit besonderem Vorteil ist vorgesehen, daß das den jeweiligen Hohlraum bildende Fugenrandprofil eine muldenförmige Vertiefung mit einem im wesentlichen horizontalen und einem im wesentlichen vertikalen Randabschnitt aufweist Dabei erstreckt sich nach einem Vorschlag der Erfindung der horizontale Randabschnitt etwa auf halber Höhe der Vertiefung in Richtung der Fuge, während der vertikale Randabschnitt auf der von der Fuge abgewandten Seite bis zur Fahrbahnoberkante verläuft Die in den Hohlraum eines derartigen Fugenrandprofils eingepreßte Verdickung des Dichtungsbandes liegt somit unter Vorspannung einerseits an dem vertikalen Randabschnitt des Hohlraumes an, während sie andererseits satt auf dem horizontalen Randabschnitt aufliegt, so daß hier ein stets tragendes Auflager für das Dichtungsband bestehtIt is particularly advantageously provided that the joint edge profile forming the respective cavity has a trough-shaped recess with an essentially horizontal and an essentially vertical edge section. According to a proposal of the invention, the horizontal edge section extends approximately halfway up the recess in the direction of the joint, while the vertical edge section runs on the side facing away from the joint to the upper edge of the roadway. The thickening of the sealing tape pressed into the cavity of such a joint edge profile is thus under tension on the one hand against the vertical edge section of the cavity, while on the other hand it lies snugly on the horizontal edge section, so that there is always a supporting bearing for the sealing tape

Nach einem weiteren Vorschlag der Erfindung kann der vertikale Randabschnitt ein nach innen umgebördelter Rand des Fugenrandprofils sein, dessen untere horizontale Kante von der Stützfläche der Verdickung hintergriffen wird. Da die Verdickung des Dichtungsbandes schräg von oben nach unten in den Hohlraum eingepreßt wird, ist durch diese auf besonders einfache Weise getroffene Anordnung der an der Stützfläche anliegenden Innenfläche des Hohlraumes eine zuverlässige Verkeilung des Dichtungsbandes sichergestellt während das Einknöpfen der Verdickung in den Hohlraum einfach auszuführen ist.According to a further proposal of the invention, the vertical edge section can be an inwardly flanged edge of the joint edge profile, the lower horizontal edge of which is gripped by the supporting surface of the thickening. Since the thickening of the sealing tape is pressed obliquely from top to bottom into the cavity, this arrangement of the inner surface of the cavity adjacent to the supporting surface ensures a reliable wedging of the sealing tape while the buttoning of the thickening into the cavity is simple to carry out .

Mit Vorteil ist femer vorgesehen, daß die vorspringende Nase in dem Bereich der Verdickung angeformt ist der in Einbaulage an dem vertikalen Randabschnitt des Fugenrandprofils anliegt Durch die in Einbaulage zusammengedrückte Nase wird in diesem besonders gefährdeten Bereich selbst dann das Eindringen von Schmutz und Feuchtigkeit verhindert, wenn bei Breitstellung der Fugen Zugkräfte in dem Dichtungsband auftreten. Gleichzeitig wird ein Anpreßdruck der Verdickung gegen den horizontalen Randabschnitt des Fugenrandprofils erzeugt, so daß bei Engstellung der Fugen ein Aufwölben der Verdickung und ein sich Lösen des Dichtungsbandes von dem horizontalen Randabschnitt verhindert ist.It is also advantageously provided that the projecting nose is formed in the area of the thickening which, in the installed position, bears against the vertical edge section of the joint edge profile. The compressed nose in the installed position prevents the ingress of dirt and moisture even in this particularly vulnerable area if when the joints are opened, tensile forces occur in the sealing tape. At the same time, a contact pressure of the thickening is generated against the horizontal edge section of the joint edge profile, so that when the joints are narrowed, bulging of the thickening and loosening of the sealing tape from the horizontal edge section is prevented.

Es kann ferner mit Vorteil vorgesehen sein, daß die Stützfläche der Verdickung in Richtung von der Fuge wegweisend geneigt verläuft, d.h. zur Außenseite des Dichtungsbandes abfällt Entsprechend ist die Kante des Fugenrandprofils zur Stützfläche der Verdickung korrespondierend geneigt, so daß in der Einbaulage der Verdickung auch im Bereich der Stützfläche ein Anpreßdruck erzeugt wird, der für einen festen Halt und eine sichere Abdichtung in diesem Bereich sorgt Die Verdickung weist im Bereich der Stützfläche vorteilhaft einen Hohlraum auf, der entweder durch eine Hohlkammer oder von einem durchgehenden Loch gebildet wird und es ermöglicht, daß der an die Stützfläche angrenzende Vorsprung in Richtung dieses Hohlraumes ausweichen kann, wenn das Dichtungsband in das Fugenrandprofif eingesetzt wird. Zweckmäßigerweise weist die Breite der Verdickung im Verhältnis zum Eintrittsquerschnitt des Fugenrandprofils ein Übermaß auf, so daß das Dichtungsband mit der Verdickung und der Vorspannung in dem Fugenrandprofil gehalten wird.It can also be advantageously provided that the support surface of the thickening is inclined in the direction pointing away from the joint, i.e. The edge of the joint edge profile is inclined correspondingly to the supporting surface of the thickening, so that in the installed position of the thickening a contact pressure is also generated in the area of the supporting surface, which ensures a firm hold and a secure seal in this area. The thickening advantageously has a cavity in the area of the support surface, which is either formed by a hollow chamber or a through hole and enables the projection adjacent to the support surface to move in the direction of this cavity when the sealing tape is inserted into the joint edge profile. The width of the thickening expediently has an excess in relation to the entry cross section of the joint edge profile, so that the sealing tape with the thickening and the pretension is held in the joint edge profile.

Die vorspringende Nase verläuft zweckmäßigerweise im entspannten Zustand im wesentlichen im spitzen Winkel zu dem entsprechenden Wandabschnitt Dadurch läßt sich eine weitgehend gleichmäßige Verteilung der Vorspannung erzielen.The projecting nose expediently runs in the relaxed state essentially at an acute angle to the corresponding wall section. This allows a largely uniform distribution of the pretension to be achieved.

Nach einem weiteren Vorschlag der Erfindung weist die Verdickung in Einbaulage einen im wesentlichen horizontalen Abschnitt auf, der an dem horizontalen Randabschnitt des Fugenrandprofils anliegt Dadurch ist in diesem Bereich ein großflächiges Auflager für das Dichtungsband geschaffen, das infolge der Vorspannung stets tragend ist Auf diese Weise kann das Dichtungsband der einwirkenden Verkehrslast lange standhaften, so daß seine Nutzungsdauer beträchtlich verlängert ist Die Oberseite der Verdickung fluchtet in Einbaulage mit der Fahrbahnoberkante. Durch diese Ausbildung, bei der keinerlei Aussparungen im Fugenrandbereich in der Oberfläche des Dichtungsbandes ausgebildet sind, ist eine Ansammlung von stehendem Wasser und von Schmutz in diesem Bereich verhindert.According to a further proposal of the invention, the thickening in the installed position has a substantially horizontal section which rests on the horizontal edge section of the joint edge profile. This creates a large-area support for the sealing tape in this area, which is always load-bearing due to the prestressing the sealing tape of the traffic load acting for a long time, so that its service life is considerably extended. The top of the thickening is flush with the top of the road in the installed position. This design, in which no recesses are formed in the joint edge area in the surface of the sealing tape, prevents standing water and dirt from accumulating in this area.

Nach einem weiteren Vorschlag der Erfindung ist das Dichtungsband im Bereich der Fuge als Hohlprofil ausgebildet. Dabei wird das Hohlprofil durch rautenförmig verlaufende Rippen gebildet Um bei Engstellung der Fuge ein Aufwölben der Oberkante des Hohlprofils zu vermeiden, ist das Hohlprofil an seiner Unterseite insgesamt V-förmig ausgebildet An seiner Oberseite weist das Hohlprofil vorteilhafte V-förmige Hohlräume zwischen den rautenförmig verlaufenden Rippen auf, deren Oberkanten mit der eingebauten Verdickung und der Fahrbahnoberkante fluchten. Die diagonal verlaufenden Rippen stabilisieren dabei das zwischen den Fugenrändem befindliche Hohlprofil des Dichtungsbandes derart, daß eine vollkommen ebene Ausbildung der an die Verkehrsfläche angrenzenden Oberfläche des Dichtungsbandes in jeder Fugenstellung, also auch bei Engstellung der Fuge, sichergestellt ist. Soweit sich in den V-förmigen Hohlräumen der Oberseite des Hohlprofils Wasser und Schmutz ansammelt, beeinträchtigt dies nicht die Nutzungsdauer des Dichtungsbandes. Insgesamt ist bei der erfindungsgemäßen Vorrichtung ein unter den in der Praxis auftretenden Umständen vollständig dichter Anschluß des Dichtungsbandes an die Fugenränder sichergestellt, so daß hier weder Feuchtigkeit noch Schmutz eintreten noch ein vertikales Abheben des Fugenbandes von dem Fugenrandprofil stattfinden kann, so daß die Nutzungsdauer des Dichtungsbandes verlängert und das Fugenrandprofil vor Korrosion geschützt ist.According to a further proposal of the invention, the sealing tape is designed as a hollow profile in the region of the joint. The hollow profile is formed by diamond-shaped ribs.To avoid bulging of the upper edge of the hollow profile when the joint is narrowed, the hollow profile has an overall V-shape on its underside. On its top side, the hollow profile has advantageous V-shaped cavities between the diamond-shaped ribs whose upper edges are aligned with the built-in thickening and the upper edge of the road. The diagonally running ribs stabilize the hollow profile of the sealing tape located between the joint edges in such a way that a completely flat design of the surface of the sealing tape adjacent to the traffic surface is ensured in every joint position, that is to say even when the joint is narrow. Insofar as water and dirt accumulate in the V-shaped cavities on the top of the hollow profile, this does not affect the service life of the sealing tape. Overall, in the device according to the invention, a completely tight connection of the sealing tape to the joint edges is ensured under the circumstances that occur in practice, so that neither moisture nor dirt enter nor a vertical lifting of the joint tape from the joint edge profile can take place, so that the useful life of the sealing tape extended and the joint edge profile is protected against corrosion.

Fig. 1 zeigt von einem bevorzugt aus einem gummiartigen Werkstoff bestehenden Dichtungsband 1 eine der beiden seitlichen Verdickungen 2 im nicht eingebauten Zustand. Die Verdickung 2 hat eine ebene Oberseite 3, die im Einbauzustand des Dichtungsbandes 1 bündig mit der Straßenoberkante 4 (Figuren 2 und 4) verläuft, und eine untere Auflagefläche 5, die ein Auflager für die Verdickung bildet. Die Verdickung 2 ist ferner mit einer Nase 6 versehen, die im eingebauten Zustand des Dichtungsbandes zusammengedrückt wird, so daß sie dann im wesentlichen vertikal bzw. horizontal verläuft. Die Verdickung 2 geht an ihrem unteren Endabschnitt in einen Steg 8 über, der in einer Wulst 9 endet.1 shows one of the two lateral thickenings 2 of a sealing tape 1, preferably made of a rubber-like material, in the non-installed state. The thickening 2 has a flat upper side 3 which, when the sealing tape 1 is in the installed state, runs flush with the top edge 4 of the road (FIGS. 2 and 4), and a lower contact surface 5 which forms a support for the thickening. The thickening 2 is further provided with a nose 6 which is compressed in the installed state of the sealing tape, so that it then runs essentially vertically or horizontally. The thickening 2 merges at its lower end section into a web 8 which ends in a bead 9.

Die Verdickung 2 besitzt etwa auf halber Höhe an dem in Fig. 1 linken Rand einen an die Stützfläche 7 angrenzenden Vorsprung 7b, welcher von innen nach außen fällt und im Einbauzustand (Fig. 4) gegen eine untere Kante 18 (Fig. 2) zur Anlage kommt In diesem Bereich befindet sich auch ein Hohlraum 7a, welcher es ermöglicht, daß der Vorsprung 7b in Richtung des Hohlraums nach innen gedrückt wird, wenn die Verdickung 2 in das Fugenrandprofil 12 eingesetzt wird (siehe Fig. 3).The thickening 2 has about halfway up the left edge in FIG. 1 a projection 7b adjoining the support surface 7, which protrudes from the inside outwards and in the installed state (FIG. 4) against a lower edge 18 (FIG. 2) In this area there is also a cavity 7a, which enables the projection 7b to be pressed inwards in the direction of the cavity when the thickening 2 is inserted into the joint edge profile 12 (see FIG. 3).

Fig. 2 zeigt einen Fugenquerschnitt mit an die Fuge 10 angrenzendem Betonunterbau 11. Das Fugenrandprofil 12 ist in ein Kunststoffbetonbett 13 eingebettet, an welches sich der Straßen asphalt 14 anschließt.Fig. 2 shows a cross-section with adjoining joints in the joint 10 concrete base 11. The joint edge profile 12 is embedded in a plastic concrete bed 13 to which the asphalt road 1 4 is connected.

Die Fugenrandprofile 12 haben einen im wesentlichen muldenförmigen Hohlraum 15. Etwa auf halber Höhe des Fugenrandprofiles 12 erstreckt sich ein horizontaler Randabschnitt 16 in Richtung der Fuge 10. Ein vertikaler Randabschnitt 17 ist am Rand des Fugenrandprofils 12 ausgebildet und erstreckt sich bis zur Fahrbahnoberkante 4.The joint edge profiles 12 have an essentially trough-shaped cavity 15. A horizontal edge section 16 extends approximately halfway up the joint edge profile 12 in the direction of the joint 10. A vertical edge section 17 is formed at the edge of the joint edge profile 12 and extends to the top edge 4 of the roadway.

In Fig. 3 ist gezeigt, wie das Dichtungsband 1 mit der Verdickung 2 in das Fugenrandprofil 12 eingesetzt wird. Hierbei wird der an die Stützfläche 7 angrenzende Vorsprung 7b in Richtung des Hohlraumes 7a nach innen gedrückt, so daß die Verdickung 2 durch den verengten Querschnitt 22 in den muldenförmigen Hohlraum 15 eingeführt werden kann.In Fig. 3 it is shown how the sealing tape 1 with the thickening 2 is inserted into the joint edge profile 12. In this case, the projection 7b adjoining the support surface 7 is pressed inward in the direction of the cavity 7a, so that the thickening 2 can be introduced into the trough-shaped cavity 15 through the narrowed cross section 22.

Fig. 4 zeigt das vollständig eingebaute Dichtungsband, wobei die seitlichen Verdickungen 2 mit ihren Oberseiten mit der Fahrbahnoberkante 4 fluchten. Die Nase 6 ist zusammengedrückt und liegt an dem vertikalen Randabschnitt 17 an. Gleichzeitig liegt der Vorsprung 7b gegen die Kante 18 an, wobei der Vorsprung 7b eine Stützfläche der Verdickung 2 in dem Hohlraum bildet. Der Steg 8 mit der Wulst 9 ist zur Fuge hin aufgebogen, so daß die Wulst 9 etwas oberhalb der Stützfläche 7a an einem Innenwandabschnitt des Fugenrandprofils 12 und der Verdickung 2 anliegt, und die Verdickung 2 in dem Hohlraum 15 verkeilt ist Die horizontale Auflagerfläche 5 der Verdickung 2 liegt unter Vorspannung auf dem horizontalen Randabschnitt 16 des Fugenrandprofils 12 auf, so daß die Verdickung insgesamt 3 Auflagerflächen 5, 6 und 7 hat, die gegen die Innenwandung des Hohlraumes 15 angepreßt werden. Durch diese Ausbildung ist ein sicherer, spatttoser Sitz des Dichtungsbandes in dem Fugenrandprofil gewährleistet.Fig. 4 shows the fully installed sealing tape, the side thickenings 2 are aligned with their tops with the top edge 4 of the roadway. The nose 6 is compressed and bears against the vertical edge portion 1. 7 At the same time, the projection 7b bears against the edge 18, the projection 7b forming a supporting surface of the thickening 2 in the cavity. The web 8 with the bead 9 is bent toward the joint, so that the bead 9 abuts slightly above the support surface 7a on an inner wall section of the joint edge profile 12 and the thickening 2, and the thickening 2 is wedged in the cavity 1 5. The horizontal bearing surface 5 the thickening 2 lies under prestress on the horizontal edge section 16 of the joint edge profile 12, so that the thickening has a total of 3 bearing surfaces 5, 6 and 7, which are pressed against the inner wall of the cavity 15. This design ensures a secure, spattless fit of the sealing tape in the joint edge profile.

Im Bereich der Fuge 10 ist das Dichtungsband 1 als Hohlprofil 19 ausgebildet Dieses Hohlprofil besteht aus rautenförmig verlaufenden Rippen 20, wobei die einzelnen Rauten an der Oberseite des Hohlprofils 19 mit der eingebauten Verdickung 2 und der Fahrbahnoberkante 4 fluchten. Zwischen den einzelnen Rauten befinden sich an der Oberseite des Hohlprofils V-förmige Hohlräume 21. An der Unterseite ist das Hohlprofil 19 insgesamt V-förmig geformtIn the area of the joint 10, the sealing tape 1 is designed as a hollow profile 19. This hollow profile consists of diamond-shaped ribs 20, the individual diamonds on the top of the hollow profile 19 being aligned with the built-in thickening 2 and the top edge 4 of the roadway. V-shaped cavities 2 1 are located on the top of the hollow profile between the individual rhombuses. On the underside, the hollow profile 19 is V-shaped overall

Die diagonal verlaufenden Rippen 20 ermöglichen eine einwandfreie Abtragung der Vertikal lasten zum Fugenrand hin. Durch seine besondere Ausbildung ist das Hohlprofil derart stabilisiert, daß seine Oberfläche auch bei Engstellung der Fuge vollkommen mit der Fahrbahnoberkante fluchtetThe diagonally running ribs 20 enable the vertical loads to be removed properly towards the joint edge. Due to its special design, the hollow profile is stabilized in such a way that its surface is perfectly aligned with the top of the road even when the joint is narrow
