Description

Die vorliegende Erfindung betrifft eine Überbrückungsvorrichtung in Mittelträgerbauweise für eine Bauwerksfuge zwischen zwei Bauwerksteilen mit wenigstens zwei jeweils einem Bauwerksteil zugeordneten Randprofilen und wenigstens einem Mittelträger der zwischen den Randprofilen und auf wenigstens einer die Bauwerksfuge überbrückenden Traverse angeordnet ist.The present invention relates to a bridging device in center-beam construction for a building joint between two structural parts with at least two each associated with a building part edge profiles and at least one center support is disposed between the edge profiles and at least one of the building structure bridging traverse.

Im Allgemeinen werden solche Vorrichtungen dazu eingesetzt, Bauwerksfugen zwischen zwei Bauwerksteilen, insbesondere zwischen zwei Brückenteilen wie beispielsweise einem Brückenkopf bzw. Widerlager und einem Brückenaufleger bzw. Brückenträger oder aneinander angrenzender Brückenträger, so zu überbrücken, dass Fahrzeuge und Lebewesen gefahrlos von einem Bauteil zum anderen Bauteil gelangen können.In general, such devices are used to bridge building joints between two parts of the structure, in particular between two bridge parts such as a bridgehead or abutment and a bridge support or bridge girder or adjoining bridge girder so that vehicles and animals safely from one component to another component can reach.

Die auch Bewegungsfugen oder Dehnfugen genannten Bauwerksfugen, dienen dem Ausgleich von Bewegungen der Bauwerksteile zueinander, um so eine Beschädigung oder Zerstörung der Bauwerksteile zu vermeiden. Die Größe der Bauwerksfuge wird daher so gewählt, dass sich die Bauwerksteile im Laufe ihrer Nutzung mit möglichst großer Wahrscheinlichkeit nicht berühren.The construction joints also called movement joints or expansion joints, serve to compensate for movements of the building parts to each other, so as to avoid damage or destruction of the building parts. The size of the building gap is therefore chosen so that the building parts in the course of their use with the greatest possible probability do not touch.

Die Bewegungen die die Bauwerksteile im Laufe ihrer Nutzung erfahren, lassen sich hierbei in zwei Kategorien einteilen, nämlich in ordentliche Bewegungen im Gebrauchszustand sowie außerordentlichen Bewegungen aufgrund seltener Lasteinwirkungen.The movements that the building parts experience in the course of their use, can be divided into two categories, namely in proper movements in use and extraordinary movements due to rare load effects.

Bewegungen im Gebrauchszustand treten quasi ständig, regelmäßig und/oder dauerhaft auf. Zu den Bewegungen des Gebrauchszustandes zählen beispielsweise Bewegungen, die durch thermische Ausdehnung bedingt sind oder sich durch Kriechen und Schwinden der eingesetzten Baustoffe ergeben. Ferner sind hierzu auch Bewegungen aus Belastungen zu zählen, die durch den Gebrauch der Bauwerksteile herrühren, wie beispielsweise durch Passage von Personen und/oder Fahrzeugen bedingten Verkehrslasten, Bremslasten beim Abbremsen von Fahrzeugen, Windlasten, etc..Movements in the state of use occur almost constantly, regularly and / or permanently. The movements of the state of use include, for example, movements that are caused by thermal expansion or result from creeping and shrinkage of the materials used. Furthermore, this also movements from burdens include, resulting from the use of structural parts, such as caused by passage of people and / or vehicles traffic loads, braking loads when braking vehicles, wind loads, etc ..

Außerordentliche Bewegungen treten wie der Name schon sagt relativ selten auf. Meist sind es größere Bewegungen aus Belastungen wie Erdebeben, Baugrundbewegungen, Explosionslasten, Lasten aus dem Anprall von Gegenständen oder Fahrzeugen, etc..Extraordinary movements, as the name implies, are relatively rare. In most cases, it is larger movements from burdens such as earthquakes, building ground movements, explosion loads, loads from the impact of objects or vehicles, etc.

Überbrückungsvorrichtungen für Bauwerksfugen, die solche Bewegungen der Bauwerksteile kompensieren sind aus dem Stand der Technik in vielfältigen Ausführungsformen bekannt. Eine bewährte Form einer Überbrückungsvorrichtung ist die als Mittelträgerbauweise oder Lamellenbauweise bekannte Variante. Hier weist die Überbrückungsvorrichtung wenigstens einen Mittelträger auf, der auf wenigstens einer dreh- und/oder verschiebbar an den angrenzenden Bauwerksteilen gelagerten Traverse fest angeordnet ist. Ist der zu überbrückende Bauwerksspalt größer, weist die Überbrückungsvorrichtung mehrere Mittelträger auf, die jeweils mit einer eigenen Traverse verbunden sind. Die Traversen sind hierbei meist in sogenannten Traversenkästen im jeweiligen Bauwerksteil eingebaut.Bridging devices for building joints, which compensate for such movements of the building parts are known from the prior art in various embodiments. A proven form of a lock-up device is known as the center-carrier construction or lamella design variant. Here, the bridging device has at least one center carrier, which is fixedly arranged on at least one traverse mounted rotatably and / or displaceably on the adjacent building parts. If the building gap to be bridged is larger, the bridging device has a plurality of center supports, which are each connected to their own crossbar. The trusses are usually installed in so-called truss boxes in the respective building part.

Damit die variablen Abstände der einzelnen Mittelträger zueinander bzw. zu den Randträgern bei Bewegungen der Bauwerksteile möglichst gleich bleiben, oder um ein Auswandern der Mittelträger zu verhindern, werden sogenannte Steuerungsvorrichtungen eingesetzt. Diese greifen an den Traversen des jeweiligen Mittelträgers an und halten die variablen Abstände zwischen den einzelnen Mittelträgern bzw. zu den Randträgern weitestgehend konstant. Solche Steuerungen werden beispielsweise durch Federketten, Scheren oder auch mit Hilfe sogenannter Schwenktraversen gebildet.So that the variable distances of the individual center supports to each other or to the edge beams remain as constant as possible during movements of the building parts, or to prevent emigration of the center support, so-called control devices are used. These act on the trusses of the respective center carrier and keep the variable distances between the individual center carriers or to the edge carriers largely constant. Such controls are formed for example by spring chains, scissors or with the help of so-called pivoting traverses.

Um die Bauwerksteile auch bei Extremereignissen - und den damit einhergehenden außerordentlichen Bewegungen - schadfrei zu halten, können heute zusätzliche Sicherheitseinrichtungen an den Überbrückungsvorrichtungen als separate Bauteile eingesetzt werden. Diese Sicherheitseinrichtungen geben auf unterschiedliche Weise zusätzlichen Weg für die Bewegung der Bauwerksteile in der Bauwerksfuge frei.In order to keep the building components harmless even in extreme events - and the associated extraordinary movements - today additional safety devices can be used on the bridging devices as separate components. These safety devices release in different ways additional way for the movement of the building parts in the building joint.

Vor dem Hintergrund der von vielen Baunormen geforderten Nutzbarkeit der Überbrückungsvorrichtung durch Rettungskräfte nach Extrembelastungen, wie einem Erdebeben, wirken die heutigen Sicherheitsvorrichtungen so, dass die Überbrückungsvorrichtung vor einer Beschädigung durch die sich stark bewegenden Bauwerksteile geschützt wird. Dies geschieht in der Regel dadurch, dass die Überbrückungsvorrichtung als solche zumindest teilweise aus der Bauwerksfuge hinausgeführt wird. Eine solche Sicherheitseinrichtung ist beispielsweise aus der EP 0 821 104 A2 der Anmelderin bekannt, die auch als Fusebox bezeichnet wird.Against the background of the required by many building standards usability of the lock-up device by rescue workers after extreme loads, such as a earthquake, today's safety devices act so that the lock-up device is protected from damage by the strongly moving parts of the building. This is usually done by the fact that the bridging device is as such at least partially led out of the building joint. Such a safety device is for example from the EP 0 821 104 A2 the applicant known, which is also called Fusebox.

Auch wenn diese bekannten Überbrückungsvorrichtungen eine schadfreie Bewegung der Bauwerksteile sowohl im Gebrauchszustand wie auch bei Extremereignissen zueinander in erwiesener Weise ermöglichen, benötigen sie doch eine Vielzahl an Funktionsteilen, sind aufwändig herzustellen und haben einen relativ hohen Platzbedarf.Although these known bridging devices allow a damage-free movement of the building parts both in use and in extreme events to each other in a proven manner, yet they require a variety of functional parts, are complex to manufacture and have a relatively large amount of space.

Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, eine Überbrückungsvorrichtung in Mittelträgerbauweise für eine Bauwerksfuge aufzuzeigen, die einfacher aufgebaut ist, folglich auch geringere Kosten für die Herstellung mit sich zieht und auch nach einem Extremereignis durch Rettungsdienste sicher überfahrbar bleibt.Against this background, it is an object of the present invention to provide a bridging device in center-beam construction for a building joint, which is simpler in construction, thus also lower production costs and even after an extreme event by emergency services safely traversable.

Die Lösung der Aufgabe gelingt mit einer Vorrichtung gemäß Anspruch 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.The object is achieved with a device according to claim 1. Advantageous developments of the invention are described in the subclaims.

Die erfindungsgemäße Überbrückungsvorrichtung zeichnet sich also gegenüber den eingangs geschilderten Überbrückungsvorrichtungen dadurch aus, dass sie wenigstens zwei Mittelträger aufweist, die auf einer gemeinsamen Traverse in einem im Gebrauchszustand fixierten Abstand zueinander schubfest angeordnet sind wobei die Verbindung zwischen wenigstens einem Mittelträger und der Traverse in der Art einer Sollbruchstelle ausgebildet ist.The bridging device according to the invention is thus distinguished from the above-described bridging devices in that it has at least two center supports, which arranged on a common cross member in a fixed in use state distance to each other shear-resistant are where the connection between at least one center carrier and the traverse is designed in the manner of a predetermined breaking point.

Dieser Lösungsansatz fußt auf dem Gedanken, die Zahl der beweglichen Mittelträger in der Überbrückungslösung vor allem an der Größe der Bewegungen der Bauwerksteile im Gebrauchszustand zu orientieren und nicht wie heute üblich an der Größe der maximal aufzunehmenden Wege bei außerordentlichen Bewegungen bzw. Lasten.This approach is based on the idea to orientate the number of movable center support in the bridging solution mainly on the size of the movements of the building parts in use and not as usual today on the size of the maximum pathways to be included in extraordinary movements or loads.

Hierzu wird im völligen Bruch mit den bestehenden Lösungsansätzen ein gezieltes Versagen in der Überbrückungskonstruktion selbst herbeigeführt. Dies dadurch, dass die im außerordentlichen Lastfall von der Überbrückungsvörrichtung aufzunehmende größere Bewegung der Bauwerksteile durch ein gezieltes Versagen der Sollbruchstelle zwischen dem Mittelträger und der jeweiligen Traverse kompensiert wird. So können die im Gebrauchszustand zueinander auf einer gemeinsamen Traverse in Ihrer Lage fixierten Mittelträger im außerordentlichen Lastfall zusammengeschoben oder auseinandergezogen werden, ohne dass die Nutzbarkeit der Überbückungskonstruktion dadurch leidet. Denn die von der Traverse bzw. den Traversen abgescherten bzw. abgerissenen Mittelträger bleiben nach Untersuchungen der Anmelderin in der Regel selbst ohne besondere Maßnahmen auf der Traverse liegen.For this purpose, a complete failure with the existing approaches to a targeted failure in the bridging construction itself is brought about. This is due to the fact that the larger movement of the structural parts to be absorbed by the bridging device in the event of an extraordinary load is compensated by a targeted failure of the predetermined breaking point between the center girder and the respective crossbeam. Thus, the in use state to each other on a common traverse fixed in their position center girder can be pushed together or pulled apart in an extraordinary case, without the usability of Überbückungskonstruktion suffers. Because the sheared off from the traverse or the trusses or demolished center support remain according to investigations by the applicant usually even without special measures on the traverse lie.

Die erfindungsgemäße Lösung hat den Vorteil, dass wesentlich weniger Funktionsteile für die Steuerung der Abstände der Mittelträger benötigt werden. So kann im Extremfall sogar vollständig auf eine Steuerungsvorrichtung verzichtet werden, da die Abstände zwischen allen Mittelträgern im Gebrauchszustand fixiert sind und nur die Abstände zu den Randträgern variabel sind. Auch kann auf platzbeanspruchende zusätzliche Sicherungskomponenten, wie die sogenannten Fuseboxen, verzichtet werden.The solution according to the invention has the advantage that significantly fewer functional parts are required for the control of the distances of the center girders. Thus, in extreme cases, even completely dispensed with a control device, since the distances between all center carriers are fixed in use and only the distances to the edge beams are variable. Also can be dispensed with space-demanding additional security components, such as the so-called Fuseboxen.

Die gesamte Konstruktion ist somit wirtschaftlicher auszuführen, hat eine größere Lebensdauer sowie einen geringern Wartungsaufwand als die aus dem Stand der Technik bekannten Überbrückungsvorrichtungen.The entire construction is thus more economical to perform, has a longer life and a lower maintenance than the known from the prior art bridging devices.

Zweckmäßigerweise ist die in der Art einer Sollbruchstelle ausgeführte Verbindung zwischen Traverse und Mittelträger so ausgelegt, dass sie bei einer außerordentlichen Bewegung der Bauwerksteile zueinander versagt. Die zum Auslösen der Sollbruchstelle notwendige Krafteinleitung erfolgt durch eine Berührung des Mittelträgers mit einem benachbarten Randprofil und/oder einem benachbarten Mittelträger.Appropriately, the executed in the manner of a predetermined breaking point connection between traverse and center girder is designed so that it fails in an extraordinary movement of the building parts to each other. The introduction of force necessary for triggering the predetermined breaking point is effected by touching the center support with an adjacent edge profile and / or an adjacent center support.

Folglich kann die Verbindung so ausgeführt werden, dass die Versagenskraft zuverlässig vorab definiert und minimiert wird. Des Weiteren ergibt sich so auch eine Staffelung des Schadensumfangs bei Extremereignissen, da die Verbindungen der einzelnen Mittelträger nacheinander und nicht gleichzeitig versagen. Letztlich können so auch die Abmessungen der Überbrückungsvorrichtung minimiert werden, da die Traversenkästen wesentlicher kürzer ausgeführt werden können, da die Überbrückungsvorrichtung durch gezieltes eigenes Verformen Weg in der Bauwerksfuge freigibt und nicht mehr auf wesentlich größere Bewegungen ausgelegt sein muss.Consequently, the connection can be made so that the failure force is reliably predefined and minimized. Furthermore, this also results in a staggering of the extent of damage in extreme events, since the connections of the individual means carriers successively and not fail simultaneously. Ultimately, so can the dimensions of the lock-up device can be minimized, since the truss boxes can be made significantly shorter, since the lock-up device releases targeted by own deformation path in the building joint and no longer has to be designed for much larger movements.

Es ist von Vorteil, wenn die in der Art einer Sollbruchstelle ausgeführte Verbindung als formschlüssige, kraftschlüssige und/oder stoffschlüssige Verbindung ausgeführt ist. So kann die Verbindung beispielsweise eine Schweißverbindung, eine Bolzenverbindung oder auch eine Verbindung mit Klemmen sein. Dabei hat die kraftschlüssige Verbindung den Vorteil, dass sie nach einem Extremereignis mit verhältnismäßig geringem Aufwand ertüchtigt werden kann. Zum Anderen kann so die Versagenskraft, beispielsweise durch mit unterschiedlicher Kraft angezogene Schraubbolzen variabel eingestellt werden.It is advantageous if the executed in the manner of a predetermined breaking point connection is designed as a positive, non-positive and / or cohesive connection. For example, the connection may be a welded connection, a bolt connection or even a connection with clamps. The non-positive connection has the advantage that it can be upgraded after a extreme event with relatively little effort. On the other hand, the failure force, for example, by tightened with different force bolts can be variably adjusted.

Vorteilhafterweise ist zumindest en Mittelträger zusätzlich so gegen Abheben gesichert, dass er nach einer außerordentlichen Bewegung der Bauwerksteile und dem damit einhergehenden Versagen der Sollbruchstelle bzw. der Sollbruchstellen auf der bzw. den Traversen liegen bleibt. Die Sicherung kann auf beliege geeignete Weise zum Beispiel durch Klauen, Bügel, Seile oder dergleichen erfolgen. Folglich bleibt die Überbrückungsvorrichtung auch nach einem Extermereignis insbesondere für Rettungskräfte mit nochmals gesteigerter Sicherheit überfahrbar.Advantageously, at least one center support is additionally secured against lifting so that it remains lying on the truss or trusses after an extraordinary movement of the structural parts and the associated failure of the predetermined breaking point or predetermined breaking points. The securing can be done in any suitable manner, for example by claws, straps, ropes or the like. Consequently, the bridging device remains traversable even after a Extermereignis especially for rescue workers with even increased security.

Zweckmäßigweise weisen die Randprofile und/oder die Mittelträger Profilanprallflächen auf, die so ausgestaltet sind, dass zumindest ein Mittelträger bei einer außerordentlichen Bewegung der Bauwerksteile nach Oben aus der Überbrückungsvorrichtung geführt wird. So können die Profilanprallflächen eines Randprofils und eines Mittelträgers bzw. benachbarter Mittelträger alternierend angeschrägt ausgeführt sein, sodass sich eine rampenartige Anprallfläche ergibt, über welche der Mittelträger bei Krafteinleitung nach Oben geführt wird. Dadurch kann zusätzlicher Weg bei einer außerordentlichen Bewegung freigegeben werden.Advantageously, the edge profiles and / or the center support profile impact surfaces, which are designed so that at least one center support is guided in an extraordinary movement of the building parts to the top of the lock-up device. Thus, the profile impact surfaces of an edge profile and a center support or adjacent center support can be performed alternately bevelled, so that there is a ramp-like impact surface over which the center support is guided at force application to the top. This allows additional path to be released during an extraordinary movement.

Ferner ist es vorteilhaft, wenn der im Gebrauchszustand fixierte Abstand zwischen benachbarten Mittelträgern im Bereich zwischen 40 mm und 100 mm liegt. Ebenfalls vorteilhaft ist es, wenn der im Gebrauchszustand variable Abstand zwischen einem Randprofil und dem benachbarten Mittelträger und/oder zwischen zwei zueinander verschieblich gelagerten Mittelträgern minimal 0 mm und maximal 100 mm beträgt. Diese Abstände haben sich gerade bei Fahrbahnübergängen als geeignet herauskristallisiert, wobei ein großer Abstand eine besonders wirtschaftliche und das kleinere Maß eine besonders komfortabel überfahrbare Überbrückungsvorrichtung bedingt.Furthermore, it is advantageous if the distance between adjacent center carriers fixed in the use state lies in the range between 40 mm and 100 mm. It is also advantageous if the variable distance between an edge profile and the adjacent center support and / or between two mutually displaceably mounted center supports amounts to at least 0 mm and a maximum of 100 mm. These distances have just emerged as suitable for road junctions, with a large distance a particularly economical and the smaller size requires a particularly comfortable overrunning lock-up device.

Vorteilhafterweise weist die Überbrückungsvorrichtung wenigstens eine einem Bauwerksteil zugeordnete Sicherheitseinrichtung auf, die eine weitere die Bauwerksfuge schließende Bewegung der Bauwerksteile zueinander ermöglicht, wenn die in der Art einer Sollbruchstelle ausgeführten Verbindungen versagt haben. Diese gibt also einen zusätzlichen Weg frei, der bei besonders heftigen Ereignissen, wie beispielsweise sehr starken Erdbeben, zur Verfügung steht. Dies schützt die Bauwerksteile zusätzlich vor Beschädigung.Advantageously, the bridging device has at least one safety device associated with a structural part, which permits a further movement of the structural parts closing the structural joint to one another when the connections designed in the manner of a predetermined breaking point have failed. This therefore releases an additional path that is available for particularly violent events, such as very strong earthquakes. This additionally protects the structural parts against damage.

Zweckmäßigerweise weist die Sicherheitseinrichtung einer jeder Traverse zugeordnete und sich in Richtung der Oberseite des Bauwerksteils erstreckenden Rampe auf, wobei das Randprofil über einer Sollbruchstelle mit der Rampe verbunden ist. Das Randprofil und die Mittelträger sind nach Versagen der Sollbruchstelle über die Rampe aus der Überbrückungsvorrichtung führbar. Dadurch ist gewährleistet, dass die Traverse nach einem Extremereignis innerhalb der Überbrückungsvorrichtung verbleibt, und lediglich das Randprofil und die Mittelträger aus der Überbrückungsvorrichtung geführt werden. Nach dem Ereignis können die Mittelträger und das Randprofil in die Überbrückungsvorrichtung zurück geschoben werden, wodurch die Überfahrbarkeit wieder hergestellt wird. In diesem Zusammenhang ist es sinnvoll, dass die Sollbruchstelle zwischen Randprofil und Rampe für eine größere Krafteinleitung ausgelegt ist, sodass zunächst die Verbindungen zwischen den Mittelträgern und der Traverse versagen, bevor die Sollbruchstelle des Randprofils versagt. Andernfalls würde die Sicherheitseinrichtung zu früh auslösen.Expediently, the safety device has a ramp assigned to each cross member and extending in the direction of the upper side of the structural part, wherein the edge profile is connected to the ramp via a predetermined breaking point. The edge profile and the center girder are feasible after failure of the predetermined breaking point on the ramp from the lock-up device. This ensures that the traverse remains after an extreme event within the lock-up device, and only the edge profile and the center carrier are guided out of the lock-up device. After the event, the center carrier can and the edge profile are pushed back into the lock-up device, whereby the Überfahrbarkeit is restored. In this context, it makes sense that the predetermined breaking point between edge profile and ramp is designed for a greater force application, so that initially the connections between the center beams and the traverse fail before the predetermined breaking point of the edge profile fails. Otherwise, the safety device would trigger too early.

Es ist von Vorteil, wenn die Sicherheitseinrichtung ein mit der Oberseite der Bauwerksteils ebenes Abdeckungsteil zwischen der Rampe und dem Randprofil aufweist, wobei das Abdeckungsteil aus der Überbrückungsvorrichtung führbar ist. Dadurch ist die Sicherheitseinrichtung im Gebrauchszustand gut überfahrbar.It is advantageous if the safety device has a cover part, which is flat with the upper side of the structural part, between the ramp and the edge profile, wherein the cover part can be guided out of the bridging device. As a result, the safety device is easy to drive over in use.

Zweckmäßigerweise ist die Sicherheitseinrichtung als austauschbare Sicherungsbox ausgebildet. Somit kann die Sicherheitseinrichtung nach einer außerordentlichen Belastung schnell und kostengünstig ausgetauscht werden. Mithin ist das Bauwerk auch nach einer außerordentlichen Belastung wieder in kurzer Zeit in seinen Normalzustand versetzt und voll zu gebrauchen.Conveniently, the safety device is designed as a replaceable fuse box. Thus, the safety device can be replaced quickly and inexpensively after an extraordinary load. Thus, the building is after a extraordinary load again in a short time in its normal state and fully used.

Vorteilhafterweise ist zwischen einem Randprofil und einem Mittelträger ein Dichtprofil angeordnet, wobei das Dichtprofil bei einer öffnenden Bewegung der Bauwerksteile zueinander überdehnbar ist. Das Dichtprofil dient dem Schallschutz und Verhindert das Eindringen von Schmutz, Wasser, Tieren oder dergleichen in die Überbrückungsvorrichtung. Durch die Überdehnbarkeit wird sichergestellt, dass diese Funktion auch bei einer öffnenden Bewegung der Bauwerksteile zueinander gegeben ist.Advantageously, a sealing profile is arranged between an edge profile and a center support, wherein the sealing profile can be expanded with respect to one another during an opening movement of the building parts. The sealing profile is used for sound insulation and prevents the ingress of dirt, water, animals or the like in the lock-up device. The overextensibility ensures that this function is given to each other in an opening movement of the building parts.

Des Weiteren ist es zweckmäßig, dass zwischen einem Randprofil sowie zwischen zwei benachbarten Mittelträgern Dichtprofile angeordnet sind. Dabei ist es denkbar, dass durch diese Dichtprofile bei einer außerordentlichen öffnenden Bewegung der Bauwerksteile ein Versagen der wenigstens einen Verbindung zwischen Mittelträger und Traverse, durch diese herbeiführbar ist. Dazu müssen die Dichtprofile und deren Verbindungen mit den Randträgern und den Mittelträgern so zugfest ausgeführt sein, dass sie die sollbruchstellenartigen Verbindungen lösen können. Somit ergibt sich auch bei einer außerordentlichen öffnenden Bewegung die gestaffelte Freigabe von zusätzlichem Weg. Dies wirkt sich positiv auf die Überfahrbarkeit aus.Furthermore, it is expedient that sealing profiles are arranged between an edge profile and between two adjacent center beams. It is conceivable that a failure of the at least one connection between the center beam and Traverse, by these can be brought about by these sealing profiles in an extraordinary opening movement of the building parts. For this purpose, the sealing profiles and their connections with the edge beams and the center beams must be designed so tensile that they can solve the sollbruchstellenartigen connections. Thus, the result also in an extraordinary opening movement the staggered release of additional route. This has a positive effect on the override.

Nachfolgend wird die Erfindung anhand von in der Zeichnung gezeigten Ausführungsbeispielen näher erläutert. Darin zeigen schematisch:

The invention will be explained in more detail with reference to embodiments shown in the drawing. In it show schematically:
Fig. 1
a longitudinal section through a bridging device according to the invention according to a first embodiment; and
Fig. 2
a longitudinal section through a bridging device according to the invention with a safety device according to a second embodiment.

Fig. 1 zeigt eine erfindungsgemäße Überbrückungsvorrichtung 1 gemäß eines ersten Ausführungsbeispiels als Längsschnitt, also quer zu einer Bauwerksfuge 2 zwischen zwei Bauwerksteilen 3 und 4. Hierzu weist die Überbrückungsvorrichtung 1 zwei Randprofile 5, 6 die jeweils einem Bauwerksteil 3, 4 zugeordnet sind auf. Ferner weist die Überbrückungsvorrichtung 1 fünf doppel-T-Trägerförmige Mittelträger 7 auf, die auf einer die Bauwerksfuge 2 überbrückenden Traverse 8 angeordnet sind. In dem hier gezeigten Beispiel sind alle Mittelträger 7 schubfest mit der Traverse 8 über die Verbindungen 9 verbunden. Die Verbindungen 9 sind in der Art einer Sollbruchstelle ausgeführt, in diesem Beispiel als Schweißverbindung. Die Spalten zwischen den Mittelträger weisen also einen im Gebrauchszustand fixierten Abstand FA auf. Dieser fixierte Abstand FA kann beispielsweise 60 mm betragen. Fig. 1 shows a bridging device 1 according to the invention according to a first embodiment as a longitudinal section, ie transversely to a building joint 2 between two structural parts 3 and 4. For this purpose, the bridging device 1 has two edge profiles 5, 6 each associated with a building part 3, 4. Furthermore, the bridging device 1 has five double-T-shaped support beams 7, which are arranged on a traverse 8 bridging the building joint 2. In the example shown here, all center girders 7 are connected to the traverse 8 in a shear-resistant manner via the connections 9. The connections 9 are designed in the manner of a predetermined breaking point, in this example as a welded joint. The gaps between the center girders thus have a fixed distance FA during use. This fixed distance FA can be, for example, 60 mm.

Des Weiteren weist die Überbrückungsvorrichtung 1 sechs Dichtprofile 14 auf, die zwischen den Randprofilen 5, 6 und einem benachbarten Mittelträger 7 und zwischen benachbarten Mittelträgern 7 angeordnet sind und die durch krallenartige Überkragungen gehalten werden. Die Traverse 8 kann bei Bewegungen der Bauwerksteile 3, 4 in die jeweils einem Bauwerksteil 3, 4 zugeordneten Traversenkästen 15 hinein- und hinausbewegt werden. Hierzu ist die Traverse 8 entsprechend gelagert, wobei die Lagerung beispielsweise durch Druckgleitlager erfolgen kann.Furthermore, the bridging device 1 has six sealing profiles 14, which are arranged between the edge profiles 5, 6 and an adjacent center girder 7 and between adjacent center girders 7 and which are held by claw-like overhangs. The traverse 8 can be moved in and out of each of a building part 3, 4 associated truss boxes 15 in movements of the building parts 3, 4. For this purpose, the Traverse 8 is stored accordingly, the storage can be done for example by pressure bearings.

Bewegungen der Bauwerksteile 3, 4 zueinander, die im Gebrauchszustand auftreten, werden durch die beiden äußeren Spalte zwischen den Randprofilen 5, 6 und den jeweiligen Mittelträger 7 aufgenommen. Hierzu weisen die Spalte einen variablen Abstand VA auf. Ausgehend von einem mittleren variablen Abstand VA von beispielsweise 40 mm können so schadfreie Bewegungen von bis zu ± 80 mm je Spalt aufgenommen werden, wobei öffnende Bewegungen der Bauwerksteile 3, 4 zueinander durch eine Überdehnung des entsprechenden Dichtprofils 14 ermöglicht werden. Denkbar ist auch, dass die zu den Randprofilen 5, 6 benachbarten Mittelträger 7 verschieblich auf der Traverse 8 angeordnet sind, um so einen zusätzlichen Spalt mit variablem Abstand VA zur Aufnahme von Bewegungen der Bauwerksteile 3, 4 zueinander zu schaffen.Movements of the building parts 3, 4 to each other, which occur in use, are absorbed by the two outer gaps between the edge profiles 5, 6 and the respective center carrier 7. For this purpose, the gaps have a variable distance VA. Starting from a mean variable distance VA of, for example, 40 mm, damage-free movements of up to ± 80 mm per gap can thus be accommodated, wherein opening movements of the building parts 3, 4 to one another are made possible by an overstretching of the corresponding sealing profile 14. It is also conceivable that the adjacent to the edge profiles 5, 6 center carrier 7 are arranged displaceably on the traverse 8, so as to create an additional gap with a variable distance VA for receiving movements of the building parts 3, 4 to each other.

Nachfolgend wird nunmehr die Funktionsweise der Überbrückungsvorrichtung bei sich bewegenden Bauwerksteilen 3, 4 im Gebrauchszustand sowie bei außerordentlichen Bewegungen beschrieben. Dabei zeigt Fig. 1 in den Fig. 1a bis 1d eine unterschiedlich fortgeschrittene schließende Bewegung der Bauwerksteile 3, 4.Hereinafter, the operation of the lock-up device is described in moving structural parts 3, 4 in use and in extraordinary movements. It shows Fig. 1 in the Fig. 1a to 1d a different advanced closing movement of the building parts 3, 4.

In den Fig. 1a und 1b sind Bewegungen der Bauwerksteile 3, 4 im Gebrauchszustand dargestellt, wobei Fig. 1b die maximal mögliche Bewegung der Bauwerksteile 3, 4 zueinander im Gebrauchszustand gezeigt ist. In diesem Zustand berühren die Randprofile 5, 6 den jeweils benachbarten Mittelträger 7 und die variablen Abstände VA der Mittelträger 7 betragen 0 mm. Um bei dem oben genannten Zahlenbeispiel zu bleiben, beträgt die schließende Bewegung der Bauwerksteile 3, 4 zueinander wie in Fig. 1b dargestellt insgesamt 80 mm. Hierbei spielt es auch keine Rolle, ob sich beide Bauwerksteile bewegen, oder ob es sich um eine einseitige Bewegung handelt, da bei einseitiger Bewegung die Traverse 8 weitergeschoben wird.In the Fig. 1a and 1b are movements of the building parts 3, 4 shown in use, wherein Fig. 1b the maximum possible movement of the building parts 3, 4 to each other in use is shown. In this state, the edge profiles 5, 6 touch the respectively adjacent center support 7 and the variable distances VA of the center supports 7 are 0 mm. In order to stay with the above numerical example, the closing movement of the building parts 3, 4 to each other as in Fig. 1b represented a total of 80 mm. It also does not matter whether both parts of the building move, or whether it is a one-sided movement, since in one-sided movement, the cross member 8 is pushed on.

Eine weitere, durch eine außerordentliche Last bedingte außerordentliche Bewegung der Bauwerksteile 3, 4 zueinander ist in den Fig. 1c und 1d dargestellt.Another, caused by an extraordinary load extraordinary movement of the building parts 3, 4 to each other in the Fig. 1c and 1d shown.

Durch eine außerordentliche Bewegung der Bauwerksteile 3, 4 zueinander, die über die maximale mögliche Bewegung im Gebrauchszustand (vgl. Fig. 1 b) hinausgeht, wird eine Kraft durch die Berührung der Randprofile 5, 6 mit dem jeweiligen benachbarten Mittelträger 7 in die Sollbruchstellen 9 der Mittelträger 7 eingeleitet. Somit versagen die Sollbruchstellen 9 dieser Mittelträger 7 und geben zusätzlichen Weg für die Bewegung der Bauwerksteile 3, 4 zueinander frei. Bei einem fixen Abstand FA von 60 mm können so also weitere 120 mm an Bewegung aufgenommen werden, bis die Mittelträger 7 wiederum die benachbarten Mittelträger 7 berühren (vgl. Fig. 1 c).By an extraordinary movement of the building parts 3, 4 to each other, which exceeds the maximum possible movement in use (see. Fig. 1 b) goes out, a force is introduced by the contact of the edge profiles 5, 6 with the respective adjacent center support 7 in the predetermined breaking points 9 of the center support 7. Thus, the predetermined breaking points 9 of these center girders 7 fail and give additional way for the movement of the building parts 3, 4 to each other free. With a fixed distance FA of 60 mm, another 120 mm of movement can therefore be absorbed until the center supports 7 in turn touch the adjacent center supports 7 (cf. Fig. 1 c) ,

Bei einer weiteren Bewegung der Bauwerksteile 3,4 zueinander wird nun wiederum eine Kraft in die nächsten noch fixierten Mittelträger 7 eingeleitet, wodurch die entsprechenden Sollbruchstellen 9 versagen und weitere 120 mm an Bewegungsweg freigegeben wird, bis die nun beweglichen Mittelträger 7 den zentralen Mittelträger 7 berühren (vgl. Fig. 1c). Somit ist die maximale Bewegung der Bauwerksteile 3, 4 zueinander dargestellt, die zum Einen durch die Länge der Traverse 8 und die Traversenkästen 15 und zum anderen durch die Anzahl an Mittelträgern 7 vorgeben ist. In diesem Zustand bleibt auch die Verbindung 9 zwischen dem zentralen Mittelträger 7 und der Traverse 8 bestehen. Aus der Darstellung gemäß Fig. 1c kann man auch sehr gut erkennen, dass eine Überfahrung der Überbrückungsvorrichtung auf der Oberseite 11 der Bauwerksteile 3, 4 weiterhin problemlos möglich ist.In a further movement of the building parts 3.4 to each other now a force in the next still fixed center support 7 is initiated, whereby the corresponding predetermined breaking points 9 fail and released another 120 mm of movement path until the now movable center support 7 touch the central center support 7 (see. Fig. 1c ). Thus, the maximum movement of the building parts 3, 4 is shown to each other, which is on the one hand by the length of the cross member 8 and the truss boxes 15 and the other by the number of center beams 7 pretending. In this state, the connection 9 between the central center support 7 and the traverse 8 remains. From the illustration according to Fig. 1c can also be seen very well that an overrun of the bridging device on the top 11 of the building parts 3, 4 continue to be possible without problems.

Gemäß dem angeführten Zahlenbeispiel beträgt somit die maximal mögliche schließende Bewegung der Bauwerksteile 3, 4 zueinander, welche durch eine erfindungsgemäße Überbrückungsvorrichtung 1 zwischen den in Fig. 1 a und Fig. 1 d gezeigten Zuständen kompensiert werden kann 320 mm (= 2 x VA + 4 x FA = 2 x 40 mm + 4 x 60 mm).According to the numerical example given, the maximum possible closing movement of the building parts 3, 4 relative to one another, which is achieved by a bridging device 1 according to the invention between the in Fig. 1 a and Fig. 1 d shown conditions can be compensated 320 mm (= 2 x VA + 4 x FA = 2 x 40 mm + 4 x 60 mm).

Wird die Überbrückungsvorrichtung 1 auch für öffnende Bewegungen dieser Größenordnung ausgelegt, beträgt die Bewegungskapazität insgesamt 640 mm, wobei hiervon nur 160 mm durch die variablen Abstände VA zwischen den Randprofilen 5, 6 und den jeweiligen benachbarten Mittelträgern 7 aufgenommen werden.If the lock-up device 1 is also designed for opening movements of this magnitude, the total movement capacity is 640 mm, of which only 160 mm are received by the variable distances VA between the edge profiles 5, 6 and the respective adjacent center supports 7.

In Fig. 2 ist ein zweites Ausführungsbeispiel einer erfindungsgemäßen Überbrückungsvorrichtung 1 dargestellt. Im Unterschied zu der in Fig. 1 dargestellten Überbrückungsvorrichtung 1 weist die Überbrückungsvorrichtung 1 gemäß des zweiten Ausführungsbeispiels eine zusätzliche Sicherheitseinrichtung 10 auf, welche einem Bauwerksteil 4 zugeordnet ist. Das andere Bauwerksteil 3 weist einen verlängerten Traversenkasten 15 auf, in welchen die Traverse(n) 8 hinein- und hinausbewegbar ist bzw. sind.In Fig. 2 a second embodiment of a lock-up device 1 according to the invention is shown. Unlike the in Fig. 1 shown bridging device 1, the lock-up device 1 according to the second embodiment, an additional safety device 10 which is associated with a building part 4. The other building part 3 has a extended truss box 15, in which the Traverse (s) 8 is moved in and out or are.

Die Sicherheitseinrichtung 10 umfasst eine jeder Traverse 8 zugeordnete Rampe 12. Die Rampe 12 weist einen zur jeweiligen Traverse 8 parallelen und im Wesentlichen mit der Oberseite der Traverse 8 ebenen Abschnitt sowie einen sich in Richtung der Oberseite 11 des Bauwerksteils 4 erstreckenden ansteigenden Abschnitt auf. Das Randprofil 6 ist mit dem ebenen Abschnitt der Rampe 12 über eine Sollbruchstelle 9, hier beispielsweise eine Bolzenverbindung, schubfest verbunden.The safety device 10 comprises a ramp 12 associated with each cross member 8. The ramp 12 has a section parallel to the respective cross member 8 and substantially flat with the upper side of the cross member 8, and a rising portion extending in the direction of the upper side 11 of the structural member 4. The edge profile 6 is connected to the flat portion of the ramp 12 via a predetermined breaking point 9, here for example a bolt connection, shear-resistant.

Des Weiteren weist die Sicherheitseinrichtung 10 ein Abdeckteil 13 auf, welches möglichst bündig mit der Oberseite 11 des Bauwerksteils 4 bzw. eienr darauf angeordneten Fahrbahn oder dergleichen abschließt. Das Abdeckteil 12 erstreckt sich hierbei zwischen Randprofil 6 und Rampe 12 bzw. der Oberseite 11 des Bauwerksteils 4.Furthermore, the safety device 10 has a cover part 13, which terminates as flush as possible with the upper side 11 of the structural part 4 or eienr thereon arranged roadway or the like. The cover 12 extends here between the edge profile 6 and ramp 12 and the top 11 of the building part. 4

Nachfolgend wird nunmehr der Bewegungsablauf der der Bauwerksteile 3, 4 zueinander im Gebrauchszustand sowie bei einer außerordentlichen Bewegung beschrieben. Dabei zeigt Fig. 2 in den Fig. 2a bis 2g eine unterschiedlich fortgeschrittene schließende Bewegung der Bauwerksteile 3, 4 zueinander.Hereinafter, the sequence of movement of the structural parts 3, 4 to each other in use and in an extraordinary motion will now be described. It shows Fig. 2 in the Fig. 2a to 2g a different advanced closing movement of the building parts 3, 4 to each other.

Analog zu dem in Fig. 1 gezeigten Ausführungsbeispiel zeigt die Fig. 2b die maximal mögliche Bewegung der Bauwerksteile 3, 4 zueinander im Gebrauchszustand. In diesem Zustand berühren die Randprofile 5, 6 die entsprechenden benachbarten Mittelträger 7 und die variablen Abstände VA betragen 0 mm.Analogous to the in Fig. 1 shown embodiment shows the Fig. 2b the maximum possible movement of the building parts 3, 4 to each other in use. In this state, the edge profiles 5, 6 touch the corresponding adjacent center beams 7 and the variable distances VA are 0 mm.

Bei einer weiteren außerordentlichen schließenden Bewegung der Bauwerksteile 3, 4 versagen nacheinander die Verbindungen 9 zwischen den Mittelträgern 7 und der Traverse 8 (vgl. Fig. 2e bis 2f), wodurch bei einem fixen Abstand FA der Mittelträger 7 von 60 mm jeweils immer eine zusätzliche Bewegungskapazität von 60 mm freigegeben wird. Insgesamt können so 300 mm (= 5 x FA) an zusätzlichem Weg freigegeben werden. Bei dieser Bewegung stützt sich die Traverse 8 in dem Traversenkasten 15 des Bauwerksteils 4 ab, welchem auch die Sicherheitseinrichtung 10 zugeordnet ist.In a further extraordinary closing movement of the building parts 3, 4 fail successively the compounds 9 between the center beams 7 and the cross member 8 (see. Fig. 2e to 2f ), whereby at a fixed distance FA of the center support 7 of 60 mm always an additional movement capacity of 60 mm is always released. In total, 300 mm (= 5 x FA) can be released on an additional path. In this movement, the cross member 8 is supported in the truss box 15 of the building part 4, which is also associated with the safety device 10.

Sobald alle Spalten zwischen den Randprofilen 5, 6 und den Mittelträgern 7 bzw. zwischen den Mittelträgern 7 geschlossen sind, versagt bei einer weiteren durch Bewegung der Bauwerksteile 3, 4 zueinander induzierten Krafteinleitung die Sollbruchstelle 9 zwischen dem Randprofil 6 und der Rampe 12 (vgl. Fig. 2f und 2g).Once all the gaps between the edge profiles 5, 6 and the center beams 7 or between the center beams 7 are closed, fails in a further induced by movement of the building parts 3, 4 to each other force introduction the predetermined breaking point 9 between the edge profile 6 and the ramp 12 (see. Fig. 2f and 2g ).

Somit wird das Randprofil 6 in Richtung des ansteigenden Teils der Rampe 12 geschoben und das Abdeckteil 13 aus der Überbrückungsvorrichtung 1 entlang der Oberfläche 11 des Bauwerksteils 4 geführt (vgl. Fig. 2g). Auch hier ist gut erkennbar, dass die erfindungsgemäße Überbrückungsvorrichtung 1 noch ohne weiteres überfahrbar bleibt.Thus, the edge profile 6 is pushed in the direction of the rising part of the ramp 12 and the cover 13 is guided out of the bridging device 1 along the surface 11 of the building part 4 (see. Fig. 2g ). Here, too, it is readily apparent that the bridging device 1 according to the invention still remains traversable without further ado.
