Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Überbrücken einer Dehnungsfuge in einer Fahrbahn, insbesondere von Brücken, mit wenigstens einem in die Dehnungsfuge eingesetzten, in Richtung der Dehnungsfuge verlaufenden Zwischenprofil, das über beidseitige elastomere Abstützungen mit den Fugenrändern lastabtragend verbunden ist.The invention relates to a device for bridging an expansion joint in a carriageway, in particular bridges, with at least one intermediate profile inserted into the expansion joint and running in the direction of the expansion joint, which is connected to the joint edges in a load-bearing manner via elastomeric supports on both sides.

Um die Dehnungen unterworfenen Fugen zwischen einem Widerlager und einem Tragwerk, beispielsweise von Brücken, befahren zu können, werden diese Dehnungsfugen durch eingesetzte Zwischenprofile überbrückt, deren Anzahl in Abhängigkeit vom zulässigen Änderungsbereich der Spaltbreite unter Berücksichtigung des Umstandes gewählt wird, daß zwischen benachbarten Zwischenprofilen ein vorgegebener größter Abstand nicht überschritten werden soll. Über die Zwischenprofile ist somit nicht nur die durch das Befahren bedingte Auflast auf das Widerlager bzw. die Tragkonstruktion abzutragen, sondern auch eine möglichst gleichmäßige Fugenüberbrückung sicherzustellen, was unabhängig von der jeweiligen Fugenbreite gleichmäßige Abstände zwischen benachbarten Zwischenprofilen bzw. zwischen den Zwischenprofilen und den anschließenden Fugenrändern erfordert. Zur Erfüllung dieser Forderungen ist es bekannt, die Zwischenprofile jeweils auf in Gleitlagern des Widerlagers und des Tragwerkes verschiebbar geführten Querträgern zu lagern und gegeneinander bzw. gegenüber den Fugemnrändern durch federnde Zwischenstücke abzustützen. Diese federnden Zwischenstücke müssen nicht zwischen den Zwischenprofilen selbst, sondern können auch zwischen den mit den Zwischenprofilen fest verbundenen Querträgern angeordnet sein (CH-PS 651 339), die zu diesem Zweck gegeneinander vorragende, die federnden Zwischenstücke zwischen sich aufnehmende und bei einer Fugenvergrößerung zusammendrückende Ansätze aufweisen. Um die Abstandsverteilung zwischen den Zwischenprofilen bzw. zwischen den Zwischenprofilen und den Fugenrändern zwangsläufig gleichmäßig zu verstellen, ist es außerdem bekannt, die Zwischenprofile auf fachwerkartigen Scheren anzuordnen, die die Lastabtragung auf das Widerlager bzw. das Tragwerk übernehmen und bei ihrer Verstellung aufgrund einer Änderung der Fugenbreite eine gleichmäßige Aufteilung der Zwischenprofile über die Spaltbreite erzwingen. Nachteilig bei diesen bekannten Konstruktionen ist allerdings, daß die Lagerung der beweglichen Teile, sei es in Verschiebeführungen oder in Gelenken, Spiele mit sich bringt, die nicht nur Anlaß zu einer Lärmentwicklung beim Überfahren der Dehnungsfuge geben, sondern auch einem Verschleiß unterliegen.In order to be able to drive through the joints subjected to expansion between an abutment and a supporting structure, for example bridges, these expansion joints are bridged by inserted intermediate profiles, the number of which depends on the permissible range of change in the gap width, taking into account the circumstances is chosen that a predetermined maximum distance between adjacent intermediate profiles should not be exceeded. Using the intermediate profiles, not only the load on the abutment or the supporting structure caused by driving must be removed, but also the most uniform possible joint bridging, which, regardless of the respective joint width, ensures uniform distances between adjacent intermediate profiles or between the intermediate profiles and the subsequent joint edges required. To meet these requirements, it is known to mount the intermediate profiles in each case on cross members displaceably guided in slide bearings of the abutment and the supporting structure and to support them against one another or against the edges of the joint by resilient intermediate pieces. These resilient intermediate pieces do not have to be between the intermediate profiles themselves, but can also be arranged between the cross members fixedly connected to the intermediate profiles (CH-PS 651 339), which for this purpose protrude against each other, absorbing the resilient intermediate pieces between them and compressing them when the joints are enlarged exhibit. In order to inevitably adjust the distance distribution between the intermediate profiles or between the intermediate profiles and the joint edges, it is also known to use the intermediate profiles to be arranged on truss-like scissors, which take over the load transfer to the abutment or the supporting structure and, when adjusted due to a change in the joint width, force an even distribution of the intermediate profiles over the gap width. A disadvantage of these known constructions, however, is that the storage of the moving parts, be it in sliding guides or in joints, brings with it games which not only give rise to noise when the expansion joint is passed over, but are also subject to wear.

Schließlich ist es bekannt, das in eine Dehnfuge eingesetzte Zwischenprofil über beidseitige elastomere Abstützungen mit den Fugenrändern lastabtragend zu verbinden, wobei die über die Profillänge durchgehenden elastomeren Abstützungen auf Druck und Schub beansprucht werden. Wegen der die Änderungen der Spaltbreite aufnehmenden elastomeren Abstützungen können Lagerspiele und die damit verbundenen Nachteile insbesondere hinsichtlich der Lärmentwicklung vermieden werden. Nachteilig bei solchen elastomeren Abstützungen eines Zwischenprofiles ist allerdings, daß die zulässige Breitenän-derung der Dehnungsfuge wegen der Beschränkung auf ein einziges Zwischenprofil begrenzt ist und daß mit zunehmender Fugenbreite über die elastomeren Abstützungen eine erhebliche Zugbelastung auf die mit den elastomeren Abstützungen notwendigerweise zugfest verbundenen Fugenrändern ausgeübt wird, was insbesondere bei Betonkonstruktionen zusätzliche Maßnahmen erfordert.Finally, it is known to connect the intermediate profile inserted in an expansion joint to the joint edges in a load-bearing manner by means of elastomeric supports on both sides, the elastomeric supports passing through the profile length being subjected to pressure and thrust. Because of the elastomeric supports accommodating the changes in the gap width, bearing play and the associated disadvantages, in particular with regard to noise development, can be avoided. A disadvantage of such elastomeric supports of an intermediate profile is, however, that the permissible change in width of the expansion joint is limited due to the restriction to a single intermediate profile and that with increasing joint width over the elastomeric supports, a considerable tensile load is exerted on the joint edges that are necessarily connected to the elastomeric supports with tensile strength what additional measures are required, particularly in the case of concrete structures.

Der Erfindung liegt somit die Aufgabe zugrunde, diese Mängel zu vermeiden und eine Vorrichtung zum Überbrücken einer Dehnungsfuge in einer Fahrbahn der eingangs geschilderten Art mit einfachen Mitteln so auszugestalten, daß trotz des Einsatzes von elastomeren Abstützungen keine Einschränkungen hinsichtlich der zulässigen Änderungen bezüglich der Fugenbreite in Kauf genommen werden müssen und daß eine übermäßige Zugbelastung der Fugenränder ausgeschlossen werden kann.The invention is therefore based on the object to avoid these deficiencies and to design a device for bridging an expansion joint in a roadway of the type described above with simple means that despite the use of elastomeric supports, no restrictions with regard to the permissible changes in the joint width in purchase must be taken and that excessive Tensile stress on the joint edges can be excluded.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die elastomeren Abstützungen aus einzelnen, über die Länge des Zwischenprofils verteilten Blocklagern bestehen, die sich am Fugenrand bzw. am jeweils benachbarten Zwischenprofil abstützen.The invention solves this problem in that the elastomeric supports consist of individual block bearings distributed over the length of the intermediate profile, which are supported on the joint edge or on the adjacent intermediate profile.

Die Aufteilung der bekannten, über die Profillänge durchgehenden elastomeren Abstützungen in einzelne, über die Profillänge verteilte Blocklager bringt zunächst eine erhebliche Verringerung der mit der Fugenbreite ansteigenden Zugbelastungen der Fugenränder mit sich, weil ja die gesamte Länge aller Blocklager nur einen Bruchteil der Profillänge ausmacht. Trotzdem ist aufgrund der beim Befahren auftretenden Druckbelastungen eine vorteilhafte Lastabtragung über die elastomeren Blöcke gegeben, so daß diesbezüglich keine Einschränkungen zu befürchten sind. Die Aufteilung in einzelne Blocklager bietet darüber hinaus den zusätzlichen Vorteil, nicht nur ein Zwischenprofil, sondern auch zwei oder mehrere Zwischenprofile in die Dehnfuge einsetzen zu können, um auch größere Änderungen der Fugenbreite auszugleichen. Die elastomeren Einzelblöcke erlauben ja die Abstützung jedes Zwischenprofils an den jeweils benachbarten Zwischenprofilen bzw. an dem benachbarten Fugenrand, wobei sich wegen der gegenseitigen Druckabstützung benachbarter Profile eine Tragkonstruktion ergibt, bei der lediglich die randseitigen Zwischenprofile unmittelbar über die elastomeren Blocklager an den Fugenrändern abgestützt sind.The division of the known, continuous elastomeric supports over the profile length into individual block bearings distributed over the profile length initially leads to a considerable reduction in the tensile loads of the joint edges that increase with the joint width, because the total length of all block bearings only makes up a fraction of the profile length. Nevertheless, due to the pressure loads occurring when driving on, there is an advantageous load transfer via the elastomeric blocks, so that no restrictions are to be feared in this regard. The division into individual block stores also offers the additional advantage of not only being able to insert one intermediate profile, but also two or more intermediate profiles in the expansion joint in order to compensate for larger changes in the joint width. The individual elastomeric blocks allow each intermediate profile to be supported on the adjacent intermediate profiles or on the adjacent joint edge, whereby the mutual pressure support of adjacent profiles results in a supporting structure in which only the edge-side intermediate profiles are supported directly on the elastomeric block bearings at the joint edges.

Obwohl die beidseitige Anordnung der Blocklager sehr unterschiedlich ausfallen kann, ergeben sich besonders vorteilhafte Konstruktionsbedingungen, wenn die elastomeren Blocklager einander bezüglich des zugehörigen Zwischenprofils paarweise gegenüberliegen und an Querträgern des Zwischenprofils angeordnet sind. Damit wird für jedes Zwischenprofil über die elastomeren Blocklager eine symmetrische Abstützung gegenüber den benachbarten Zwischenprofilen bzw. den benachbarten Fugenrändern sichergestellt. Die Blocklager könnten zumindest gruppenweise in unterschiedlichen Höhen vorgesehen sein, um die gegenseitige Druckabstützung benachbarter Zwischenprofile über diese Blocklager nicht zu beeinträchtigen. Einfachere, eine geringe Bauhöhe sicherstellende Verhältnisse werden allerdings erreicht, wenn die Blocklager benachbarter Zwischenprofile gegeneinander in Profillängsrichtung versetzt sind, so daß beispielsweise ein ein Blocklager aufnehmender Querträger des einen Zwischenprofiles mit Seitenabstand zu einem ebenfalls mit einem Blocklager versehenen Querträger des benachbarten Zwischenprofils verlaufen kann.Although the arrangement of the block bearings on both sides can be very different, there are particularly advantageous design conditions if the elastomeric block bearings lie opposite one another in pairs with respect to the associated intermediate profile and are arranged on cross members of the intermediate profile. So that for each intermediate profile The elastomeric block bearings ensure symmetrical support with respect to the adjacent intermediate profiles or the adjacent joint edges. The block storage could be provided at least in groups at different heights so as not to impair the mutual pressure support of adjacent intermediate profiles via these block storage. Simpler conditions, which ensure a low overall height, are achieved, however, if the block bearings of adjacent intermediate profiles are offset from one another in the longitudinal direction of the profile, so that, for example, a crossbeam receiving a block bearing of the one intermediate profile can be spaced apart from one another and also provided with a blockbearing crossbeam of the adjacent intermediate profile.

Damit die gegenseitige Druckabstützung der Zwischenprofile über die entsprechenden Blocklager mit einfachen Konstruktionsmitteln erreicht werden kann, können die Zwischenprofile an ihrer Unterseite vorragende Auflagerbügel für die Blocklager benachbarter Zwischenprofile tragen. Die die Blocklager aufweisenden Querträger der einzelnen Zwischenprofile ragen gegen das jeweils benachbarte Zwischenprofil vor und greifen in den Auflagerbügel ein, was die erforderliche Druckabstützung mit sich bringt.So that the mutual pressure support of the intermediate profiles can be achieved with simple constructional means via the corresponding block bearings, the intermediate profiles can carry protruding support brackets for the block bearings of adjacent intermediate profiles on their underside. The crossbeams of the individual intermediate profiles, which have the block bearings, protrude against the respectively adjacent intermediate profile and engage in the support bracket, which entails the required pressure support.

Die Ausbildung der elastomeren Blocklager selbst kann entsprechend den jeweiligen Anforderungen unterschiedlich ausfallen. So könnten die einzelnen Lager aus Elastomereblöcken ohne Bewehrung bestehen, wenn mit einer begrenzten Querverlagerung gerechnet wird. Bei größeren Querverlagerungen empfiehlt es sich, die Elastomereblöcke mit parallelen Bewehrungsblechen zu versehen.The design of the elastomeric block bearings themselves can vary depending on the respective requirements. The individual bearings could consist of elastomer blocks without reinforcement if a limited transverse displacement is expected. For larger transverse displacements, it is advisable to provide the elastomer blocks with parallel reinforcement plates.

Die dargestellte Vorrichtung zum Überbrücken einer Dehnungsfuge 1 in der Fahrbahn 2 zwischen dem Widerlager 3 und dem Tragwerk 4 einer Brücke besteht gemäß dem Ausführungsbeispiel nach den Fig. 1 und 2 aus einem in die Dehnungsfuge 1 eingesetzten, in Längsrichtung der Dehnungsfuge 1 verlaufenden Zwischenprofil 5, das zu seiner Halterung mit zwei oder mehreren, über seine Länge verteilten Querträgern 6 verbunden ist. An der Unterseite der Träger 6 sind beidseits des Zwischenprofils 5 elastomere Blocklager 7 anvulkanisiert, die sich auf einer entsprechenden Stützkonstruktion 8 im Bereich der beiden Fugenränder 9 verschiebefest abstützen, wie dies insbesondere der Fig. 1 entnommen werden kann. Die durch das Befahren der Fahrbahn 2 bedingten Auflasten des Zwischenprofils 5 werden über die einzelnen Blocklager 7 auf die Stützkonstruktionen 8 abgetragen und über diese Stützkonstruktionen 8 in das Widerlager 3 bzw. das Tragwerk 4 der Brücke eingeleitet, wobei die elastomeren Blöcke dieser Blocklager 7 im wesentlichen auf Druck beansprucht werden. Wird die Fugenbreite aufgrund einer dehnungsbedingten Längenänderung des Tragwerkes 4 verändert, so wird diese Änderung der Fugenbreite über eine Querverformung der elastomeren Blocklager 7 ausgeglichen, die dabei eine entsprechende Schubbelastung erfahren. Wegen der symmetrischen Ausbildung der Blocklager 7 wird das Zwischenprofil 5 jeweils in der Fugenmitte gehalten, so daß sich der Abstand zu den benachbarten Anschlußprofilen 10 des Fugenrandes 9 gleichmäßig verändert. Die zwischen dem Zwischenprofil 5 und den Anschlußprofilen 10 üblicherweise eingesetzten, gummi-elastischen Dichtungsprofile, deren Aufnahmenuten 11 in den Anschlußprofilen 10 bzw. im Zwischenprofil 5 angedeutet sind, sind aus Übersichtlichkeitsgründen nicht dargestellt.The device shown for bridging an expansion joint 1 in the carriageway 2 between the abutment 3 and the supporting structure 4 of a bridge consists, according to the exemplary embodiment according to FIGS. 1 and 2, of an intermediate profile 5 inserted into the expansion joint 1 and running in the longitudinal direction of the expansion joint 1, which is connected to its holder with two or more cross members 6 distributed over its length. On the underside of the beams 6, elastomeric block bearings 7 are vulcanized on both sides of the intermediate profile 5, which are supported on a corresponding support structure 8 in the region of the two joint edges 9 so as to be fixed against displacement, as can be seen in particular in FIG. 1. The loads on the intermediate profile 5 caused by driving on the roadway 2 are transferred to the support structures 8 via the individual block bearings 7 and introduced into the abutment 3 or the supporting structure 4 of the bridge via these support structures 8, the elastomeric blocks of these block bearings 7 essentially be subjected to pressure. If the joint width is changed due to an elongation-related change in the length of the supporting structure 4, this change in the joint width is compensated for by a transverse deformation of the elastomeric block bearing 7, which thereby corresponds Experience shear stress. Because of the symmetrical design of the block storage 7, the intermediate profile 5 is held in the middle of the joint, so that the distance to the adjacent connecting profiles 10 of the joint edge 9 changes uniformly. The rubber-elastic sealing profiles usually used between the intermediate profile 5 and the connecting profiles 10, the receiving grooves 11 of which are indicated in the connecting profiles 10 or in the intermediate profile 5, are not shown for reasons of clarity.

Das Ausführungsbeispiel nach den Fig. 3 bis 7 unterscheidet sich von dem Ausführungsbeispiel nach den Fig. 1 und 2 im wesentlichen nur dadurch, daß an Stelle eines Zwischenprofils 5 drei Zwischenprofile 5, 5a und 5b vorgesehen sind. Diese Zwischenprofile 5, 5a und 5b weisen wiederum jeweils Querträger 6, 6a und 6b mit elastomeren Blocklagern 7 auf, die an Stützkonstruktionen 8 der Fugenränder 9 bzw. an dem jeweils benachbarten Zwischenprofil 5, 5a bzw. 5b abgestützt sind. Zu diesem Zweck sind die Zwischenprofile 5, 5a und 5b mit an ihrer Unterseite vorragenden Auflagerbügeln 12 versehen. Jeder Querträger 6 des mittleren Zwischenprofiles 5 ragt endseitig in je einen Auflagerbügel 12 der benachbarten Zwischenprofile 5a und 5b, so daß das mittlere Zwischenprofil 5 über seine Blocklager 7 an den benachbarten Zwischenprofilen 5a und 5b abgestützt wird. Die seitlichen Zwischenprofile 5a und 5b stützen sich an der jeweiligen Fugenrandseite über die Blocklager 7 an den Stützkonstruktionen 8 ab, während die Blocklager 7 auf der anderen Seite der Querträger 6a bzw. 6b auf den Auflagerbügeln 12b aufruhen, in die die Querträger 6a bzw. 6b ragen. Damit ergibt sich zwischen den Zwischenprofilen 5, 5a und 5b eine gegenseitige Druckabstützung, die eine einwandfreie Lastabtragung der beim Befahren auftretenden Auflasten über die Stützkonstruktionen 8 im Bereich der Fugenränder 9 erlaubt. Da bei einer entsprechenden Schubbeanspruchung durch eine Breitenänderung der Dehnungsfuge die einzelnen Blocklager 7 in Querrichtung verformt werden, ergibt sich ein insgesamt größerer Stellbereich für die Dehnungsfuge, ohne den maximal zulässigen Abstand zwischen den Zwischenprofilen 5, 5a und 5b bzw. den Anschlußprofilen 10 zu überschreiten.The exemplary embodiment according to FIGS. 3 to 7 differs from the exemplary embodiment according to FIGS. 1 and 2 essentially only in that three intermediate profiles 5, 5a and 5b are provided instead of one intermediate profile 5. These intermediate profiles 5, 5a and 5b in turn each have cross members 6, 6a and 6b with elastomeric block bearings 7, which are supported on support structures 8 of the joint edges 9 or on the adjacent intermediate profile 5, 5a or 5b. For this purpose, the intermediate profiles 5, 5a and 5b are provided with support brackets 12 projecting on their underside. Each cross member 6 of the middle intermediate profile 5 protrudes at the end into a support bracket 12 of the adjacent intermediate profiles 5a and 5b, so that the middle intermediate profile 5 is supported via its block bearings 7 on the adjacent intermediate profiles 5a and 5b. The lateral intermediate profiles 5a and 5b are supported on the respective joint edge side via the block bearings 7 on the support structures 8, while the block bearings 7 rest on the other side of the cross members 6a and 6b on the support brackets 12b into which the cross members 6a and 6b protrude. This results in a mutual pressure support between the intermediate profiles 5, 5a and 5b, which allows a perfect load transfer of the loads occurring when driving over the support structures 8 in the area of the joint edges 9. Since the individual block bearings 7 are deformed in the transverse direction with a corresponding shear stress due to a change in the width of the expansion joint there is an overall larger adjustment range for the expansion joint, without exceeding the maximum permissible distance between the intermediate profiles 5, 5a and 5b or the connecting profiles 10.
