Ähnliche Kompensationslager sind aus dem Stand der Technik, beispielsweise der DE 198 50 946 A1 und der DE 698 913 C , in vielfältigen Ausgestaltungen bekannt. Sie dienen dazu, die durch das Bauwerk hervorgerufenen sowie auf das Bauwerk wirkenden Lasten auf einen Unterbau, bspw. ein mit dem Kompensationslager verbundenes Widerlager, ein Fundament oder einen Pfeiler, wie er zur Lagerung von Brückenbauten verwendet wird, zu übertragen. Das Kompensationslager ist hierzu über seine Bauwerkskonsole mit dem Bauwerk und mit seiner Unterbaukonsole mit dem Unterbau verbindbar.Similar compensation bearings are known from the prior art, for example the DE 198 50 946 A1 and the DE 698 913 C , known in various configurations. They serve to transmit the load caused by the structure and acting on the structure on a substructure, for example. An abutment connected to the compensation bearing, a foundation or a pillar, as used for the storage of bridges. For this purpose, the compensation bearing can be connected to the building via its building console and to the substructure with its substructure console.

An die Kompensationslager werden dabei die Anforderungen gestellt, im Rahmen ihrer Lagerfunktion sämtliche auf das Bauwerk wirkenden Lasten in den darunter liegenden Unterbau zu übertragen. Insbesondere im Falle der Verwendung des Kompensationslagers als Brückenlager soll dieses die Eignung besitzen, neben vertikal wirkenden Lasten auch horizontal wirkende Lasten sowie aus einer Verdrehung resultierende Lasten zu übertragen. Derartige Belastungssituationen ergeben sich insbesondere bei Fahrbahnbrücken im Eisenbahnbau oder Straßenverkehrsbau und resultieren u. a. aus einer durch den Fahrbetrieb hervorgerufenen Durchbiegung einzelner Brückenträger der Fahrzeugbrücke.At the compensation camps, the requirements are made to transfer in the context of their storage function all acting on the building loads in the underlying substructure. In particular, in the case of using the compensation bearing as a bridge bearing this should have the ability to transmit not only vertically acting loads but also horizontally acting loads and loads resulting from a rotation. Such load situations arise in particular at road bridges in railway construction or road construction and result u. a. from a deflection caused by the driving of individual bridge girders of the vehicle bridge.

Aufgrund der hohen Anforderungen an die Kompensationslager besteht an moderne Brückenlager ferner die konstruktive Anforderung einer einfachen Instandhaltung bzw. Instandsetzung. Um dabei eine Beeinträchtigung des auf einer Fahrzeugbrücke stattfindenden Fahrbetriebs zu vermeiden, besteht ferner die Anforderung, das Kompensationslager derart auszuführen, dass erforderliche Instandsetzungs- und/oder Instandhaltungsarbeiten in einfacher Weise auch während des regulären Fahrbetriebs auf der Fahrzeugbrücke vorgenommen werden können.Due to the high demands placed on the compensation bearings, there is also the constructive requirement for simple maintenance and repair of modern bridge bearings.

Das Radialgelenklager weist darüber hinaus den Vorteil auf, dass die Verkippbarkeit nicht auf eine Richtung senkrecht zur Körperachse beschränkt ist, sondern, dass durch die durch das Radialgelenklager bestehende Möglichkeit einer Taumelbewegung des Lagerkörpers um die Körperachse, eine Ausrichtung der Bauwerkskonsole gegenüber der Unterbaukonsole zur Gewährleistung der gewünschten Verkippbewegung nicht erforderlich ist. Darüber hinaus besteht die Möglichkeit der Verwendung standardisierter Radialgelenklager, was eine besonders einfache und kostengünstige Herstellung des Kompensationslagers erlaubt.For this purpose, the radial spherical plain bearing is fixed with an outer ring in the upper receiving opening and with an inner ring on the bearing body, so that the radial spherical plain bearing ensures both a tilting and a rotatable arrangement of the bearing body on the building console. The radial joint bearing also has the advantage that the Verkippbarkeit is not limited to a direction perpendicular to the body axis, but that by existing by the Radialgelenklager possibility of wobbling of the bearing body about the body axis, an orientation of the building console against the substructure bracket to ensure desired tilting movement is not required. In addition, there is the possibility of using standardized radial spherical plain bearings, which allows a particularly simple and cost-effective production of the compensation bearing.

Der Aufbau der Bauwerkskonsole mit dem oberen Lagerkörperhalter und/oder der Aufbau der Unterbaukonsole mit den unteren Lagerkörperhaltern kann grundsätzlich in beliebiger Weise erfolgen, wobei diese auch einstückig ausgebildet sein können. Auch ist es möglich, die Lagerkörperhalter als separate Bauteile vorzusehen, welche mit zur Verbindung mit dem Bauwerk oder dem Unterbau ausgestalteten Verbindungselementen verbunden, bspw. verschweißt sind.The structure of the building console with the upper bearing body holder and / or the structure of the base bracket with the lower bearing body holders can in principle be done in any way, which may also be integrally formed. It is also possible to provide the bearing body holders as separate components which are connected, for example welded, to connecting elements designed for connection to the building or to the substructure.

Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass die Bauwerkskonsole eine mit dem oberen Lagerkörperhalter verbundene, insbesondere verschraubte Deckplatte und/oder die Unterbaukonsole eine mit den unteren Lagerkörperhaltern verbundene, insbesondere verschraubte Grundplatte aufweist.According to a particularly advantageous embodiment of the invention, however, it is provided that the building console has a connected to the upper bearing body holder, in particular screwed cover plate and / or the substructure console connected to the lower bearing body holders, in particular screwed base plate.

Gemäß dieser Ausgestaltung der Erfindung ist vorgesehen, dass die Bauwerkskonsole über eine Deckplatte mit einem Bauwerk verbindbar ist, wobei die Deckplatte mit dem oberen Lagerkörperhalter verschraubt ist. Zur Verbindung des Kompensationslagers mit dem Unterbau kann eine Grundplatte verwendet werden, welche ebenfalls in vorteilhafter Weise mit den unteren Lagerkörperhaltern verschraubt ist.According to this embodiment of the invention, it is provided that the building console is connectable via a cover plate with a building, wherein the cover plate is bolted to the upper bearing body holder. To connect the compensation bearing with the base, a base plate can be used, which is also screwed in an advantageous manner with the lower bearing body holders.

Diese Ausgestaltung des Kompensationslagers ermöglicht eine besonders einfache und kostengünstige Herstellung des Kompensationslagers. Die Lagerkörperhalter können zur Bildung des Kompensationslagers in einfacher Weise mit der Grundplatte bzw. Deckplatte verbunden werden, wobei insbesondere die Verschraubung die Möglichkeit einer kostengünstigen Ausrichtung und späteren Instandsetzung bietet. Gegenüber einer grundsätzlich möglichen Schweißverbindung der Lagerkörperhalter mit der Grund- bzw. Deckplatte, zeichnet sich die Verschraubung ferner durch ihre verzugsfreie Lagesicherung der Lagerkörperhalter aus. Darüber hinaus kann bei der Bemessung auf eine Abminderung der Tragfähigkeit aufgrund von Kerbwirkungen bei Schweißverbindungen verzichtet werden, so dass bei Schraubverbindungen eine sehr kompakte Bauform erzielt werden kann, welche gleichzeitig eine hohe Kraftübertragung gewährleistet. Der mehrteilige Aufbau des Kompensationslagers erlaubt es darüber hinaus, das Lager aus einzelnen, standardisierten Bauteilkomponenten herzustellen, welche für sich genommen in einfacher Weise entsprechend den Anforderungen ausgelegt und anschließend durch einfache Schraubverbindungen miteinander verbunden werden können.This embodiment of the compensation bearing enables a particularly simple and cost-effective production of the compensation bearing. The bearing body holder can be connected to form the compensation bearing in a simple manner with the base plate or cover plate, in particular the screw provides the possibility of cost-effective alignment and subsequent repair. Compared to a possible possible welded joint of the bearing body holder with the base or cover plate, the screw is also characterized by their distortion-free position securing the bearing body holder. In addition, can be omitted in the design on a reduction in the load capacity due to notch effects in welded joints, so that in screw a very compact design can be achieved, which simultaneously ensures a high power transmission. The multi-part construction of the compensation bearing also makes it possible to produce the bearing of individual, standardized component components, which in itself can be designed according to the requirements in a simple manner and then connected to each other by simple screw.

Im Falle von Wartungs- und Instandsetzungsarbeiten erlaubt der modulare Aufbau darüber hinaus eine einfache Auswechselbarkeit der Standardkomponenten, so dass sehr gute Wartungsmöglichkeiten bestehen. Über die Auswahl der einzelnen Komponenten lässt sich ferner die Kapazität des Lagers in besonders einfacher und kostengünstiger Weise festlegen.In the case of maintenance and repair work, the modular design also allows easy replacement of standard components, so there are very good maintenance options. Furthermore, the capacity of the bearing can be determined in a particularly simple and cost-effective manner via the selection of the individual components.

Nach einer weiteren Ausgestaltung der Erfindung ist ferner vorgesehen, dass der obere Lagerkörperhalter in einer Vertiefung der Deckplatte und/oder die unteren Lagerkörperhalter jeweils in einer Vertiefung der Grundplatte angeordnet sind. Die Anordnung der Lagerkörperhalter in Vertiefungen, welche nach einer besonders vorteilhaften Ausgestaltung der Erfindung durch sich senkrecht zu der Körperachse erstreckenden Nuten an der Bodenplatte und/oder der Deckplatte gebildet sind, erlaubt eine besonders zuverlässige Lagesicherung der Lagerkörperhalter an der Grundplatte bzw. Deckplatte. Gegenüber einer reinen Schraub- und/oder Schweißverbindung bietet eine gemäß dieser vorteilhaften Weiterbildung vorgesehene Anordnung der Lagerkörperhalter zudem eine formschlüssige Lagesicherung der Lagerkörperhalter in einer parallel zu der Grund- oder Deckplatte verlaufenden Ebene. Eine besondere Lagesicherung wird dabei insbesondere dann erreicht, wenn die Verbindung von Lagerkörperhalter und Platte über vorgespannte Passschrauben in Verbindung mit engen Passfeldern erfolgt, wodurch in besonders vorteilhafter Weise eine sichere Kraftübertragung ohne Spiel gewährleistet werden kann.According to a further embodiment of the invention it is further provided that the upper bearing body holder are arranged in a recess of the cover plate and / or the lower bearing body holder in each case in a recess of the base plate. The arrangement of the bearing body holder in recesses, which are formed according to a particularly advantageous embodiment of the invention by perpendicular to the body axis extending grooves on the bottom plate and / or the cover plate, allows a particularly reliable securing position of the bearing body holder on the base plate or cover plate. Compared to a pure screw and / or welded connection provided according to this advantageous development arrangement of the bearing body holder also provides a positive position securing the bearing body holder in a parallel to the base or cover plate extending plane. A special position assurance is achieved in particular when the connection of bearing body holder and plate via prestressed fitting screws takes place in conjunction with tight fitting fields, whereby a safe power transmission can be ensured without play in a particularly advantageous manner.

Eine Begrenzung der in Richtung der Körperachse erfolgenden Bewegung der Bauwerkskonsole gegenüber der Unterbaukonsole, wobei der Lagerkörper gegenüber der Unterbaukonsole verschoben wird, kann grundsätzlich in beliebiger Weise erfolgen. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass der erste untere Lagerkörperhalter und/oder der zweite untere Lagerkörperhalter zur Begrenzung einer in Richtung der Körperachse des Lagerkörpers gerichteten Bewegung der Bauwerkskonsole gegenüber der Unterbaukonsole ein mit der Deckplatte in Eingriff bringbares Anschlagelement aufweist. Gemäß dieser Ausgestaltung der Erfindung ist der erste und/oder zweite untere Lagerkörperhalter mit einem Anschlagelement versehen, welches nach einer zuvor definierten, in Richtung der Körperachse des Lagerkörpers gerichteten Bewegung mit der Bauwerkskonsole in Eingriff gelangt und somit als Anschlag die maximale Verschiebbarkeit begrenzt. Die sowohl einstückig als auch mehrstückig mit den Lagerkörperhaltern ausgebildeten Anschlagelemente können an einem oder beiden Lagerkörperhaltern angeordnet sein und so eine den jeweiligen Anforderungen entsprechende Begrenzung der Verlagerbarkeit festlegen.A limitation of the movement of the building console in the direction of the body axis relative to the base console, wherein the bearing body is moved relative to the base bracket, can in principle be carried out in any desired manner. According to a particularly advantageous embodiment of the invention, however, it is provided that the first lower bearing body holder and / or the second lower bearing body holder to limit a directed towards the body axis of the bearing body movement of the building console relative to the base bracket has a engageable with the cover plate stop member.

The stop elements, which are formed integrally as well as in several pieces with the bearing body holders, can be arranged on one or both bearing body holders and thus define a limitation of the displaceability corresponding to the respective requirements.

Die Ausgestaltung des Lagerkörpers ist grundsätzlich, unter Berücksichtigung der erfindungsgemäßen Anordnung des Lagerkörpers an der Unterbau- und Bauwerkskonsole, frei wählbar. Nach einer besonders vorteilhaften Ausgestaltung der Erfindung ist jedoch vorgesehen, dass der Lagerkörper durch einen einen zylindrischen Querschnitt aufweisenden Lagerbolzen gebildet ist, dessen Längsachse die Körperachse bildet. Diese Ausgestaltung der Erfindung lässt, aufgrund der zylindrischen Geometrie, eine kompakte sowie einfache Ausgestaltung des Kompensationslagers zu. Auf umfangreiche Ausrichtungen des Lagerkörpers gegenüber der Bauwerkskonsole und/oder Unterbaukonsole kann bei der Verwendung eines Lagerbolzens verzichtet werden.The design of the bearing body is basically, taking into account the inventive arrangement of the bearing body on the substructure and building console, free selectable. According to a particularly advantageous embodiment of the invention, however, it is provided that the bearing body is formed by a cylindrical cross-section having a bearing pin whose longitudinal axis forms the body axis. This embodiment of the invention allows, due to the cylindrical geometry, a compact and simple design of the compensation bearing. On extensive alignments of the bearing body relative to the building console and / or base bracket can be dispensed with the use of a bearing pin.
