Description

Die Erfindung betrifft eine zerlegbare Spurträgerbrücke mit einem Spurträger und einem Vorbauträger. Weitere Gegenstände der Erfindung bilden eine Verlegevorrichtung, mit welcher die zerlegbare Spurträgerbrücke verlegt werden kann, ein Verlegefahrzeug sowie ein Verfahren zum Verlegen der zerlegbaren Spurträgerbrücke.The invention relates to a collapsible track carrier bridge with a track carrier and a launching support. Further objects of the invention form a laying device with which the collapsible track carrier bridge can be laid, a laying vehicle and a method for laying the collapsible track carrier bridge.

Zerlegbare Spurträgerbrücken werden sowohl im militärischen als auch in zivilen Bereichen eingesetzt und dienen als mobile Behelfsbrücken, die meist für eine begrenzte Zeit eingesetzt werden, weshalb sie möglichst schnell auf- und abbaubar sein sollen. Diese Brücken weisen üblicherweise Spurträger auf, die die gesamte Fahrbahn oder einen Teil davon bilden. Die Spurträger sind daher meist aus einem Material mit einer hohen Festigkeit gefertigt. Aus diesem Grund ist das Gewicht der Spurträger jedoch im Allgemeinen auch sehr hoch, so dass beim Verlegen hohe Hebelkräfte aufgenommen werden müssen und daher nur geringe Spannweiten erreicht werden können.Dismountable track girder bridges are used in both the military and in civilian areas and serve as mobile temporary bridges, usually for be used for a limited time, which is why they should be as fast as possible and degradable. These bridges usually have track carriers which form the entire roadway or a part thereof. The track carriers are therefore usually made of a material with a high strength. For this reason, the weight of the track carrier is generally also very high, so that when laying high leverage must be absorbed and therefore only small spans can be achieved.

Um die erreichbaren Spannweiten zu vergrößern, ist es bekannt, Vorbauträger einzusetzen. Der Vorbauträger wird als Verlegehilfe für die Spurträger verwendet. Dabei wird der Vorbauträger als erstes verlegt, so dass er den gesamten zu überspannenden Bereich überbrückt. Er kann das Gewicht der Spurträger tragen, so dass sich diese beim Verlegen auf dem Vorbauträger abstützen können und damit kein großes Gegengewicht benötigt wird.In order to increase the achievable spans, it is known to use Vorbauträger. The launch vehicle is used as a laying aid for the track carrier. In the process, the launching vehicle is laid first so that it bridges the entire area to be spanned. He can carry the weight of the track carrier, so that they can be supported when laying on the launching girder and thus no large counterweight is needed.

Da die zu überbrückenden Bereiche oftmals deutlich länger sind als die im Straßenverkehr zugelassenen Verlademaße, ist es bekannt, Vorbauträger und Spurträger in Längsrichtung jeweils in einzelne Abschnitte zu zerlegen und insoweit einen einfachen Transport zu ermöglichen. Vorbauträger und Spurträger sind beispielsweise in mehrere gleichlange Abschnitte unterteilt, die beim Verlegen der Brücke wieder aneinandergereiht und jeweils mit den entsprechenden angrenzenden Abschnitten verbunden werden.Since the areas to be bridged are often significantly longer than the load dimensions permitted in road traffic, it is known to disassemble the launching carrier and the track carrier in the longitudinal direction in each case into individual sections and to this extent allow easy transport. For example, the launching girders and the track girders are subdivided into several sections of equal length, which are lined up again when the bridge is laid and connected to the corresponding adjacent sections.

Es ist ferner bekannt, eine solche zerlegbare Spurträgerbrücke mit einer Verlegevorrichtung zu verlegen. Diese Vorrichtung weist in der Regel einen Verlegearm auf, welcher einen Vortrieb auf die entsprechenden Abschnitte bewirkt und die Brücke sukzessive über den zu überspannenden Bereich vorschiebt, so dass die einzelnen Abschnitte miteinander verbunden werden können.It is also known to lay such a collapsible track carrier bridge with a laying device. As a rule, this device has a laying arm which effects a propulsion onto the corresponding sections and advances the bridge successively over the area to be spanned, so that the individual sections can be connected to one another.

Aus der EP 0 447 825 A1 ist eine solche Spurträgerbrücke bekannt. Diese weist Vorbauträger und Spurträger auf und kann mit einem Verlegearm eines Verlegefahrzeugs verlegt werden. Der Verlegearm weist zwei Antriebe auf, von denen der erste auf den Vorbauträger und der zweite auf die Spurträger wirkt. Aus diesem Grund müssen die Spurträger sowohl an den Verlegearm bzw. an den Antrieb des Verlegearms als auch an den Zwischenrahmen angepasst sein. Das beinhaltet jedoch den Nachteil, dass Spurträger, Verlegearm und Vorbauträger nur als Einheit verwendet werden können, beispielsweise ist der einfache Austausch bzw. der Einsatz von Spurträgern anderer Brückensysteme nicht möglich.From the EP 0 447 825 A1 Such a track carrier bridge is known. This has front pontoons and track carrier and can be installed with a laying arm of a laying vehicle. The laying arm has two drives, of which the first acts on the launching beam and the second on the track carrier. For this reason, the track carrier must be adapted both to the laying arm and to the drive of the laying arm as well as to the intermediate frame. However, this involves the disadvantage that track carrier, laying arm and Vorbauträger can only be used as a unit, for example, the simple exchange or the use of track carriers other bridge systems is not possible.

Die Aufgabe der Erfindung ist daher, die Einsatzmöglichkeiten einer zerlegbaren Spurträgerbrücke bei unterschiedlichen Anforderungen zu erhöhen.The object of the invention is therefore to increase the application possibilities of a demountable track carrier bridge with different requirements.

Die Aufgabe wird mit den Merkmalen der unabhängigen Ansprüche gelöst, vorteilhafte Weiterbildungen und Ausgestaltungen sind Bestandteil der abhängigen Ansprüche.The object is achieved with the features of the independent claims , advantageous developments and refinements are part of the dependent claims.

Bei einer erfindungsgemäßen Lösung der Aufgabe sind die Spurträger und der Vorbauträger über Zwischenadapter miteinander verbunden. Durch den Einsatz von Zwischenadaptern ist es möglich, dass Vorbauträger und Spurträger nicht mehr aneinander angepasst sein müssen und mit einem Vorbauträger verschiedene Spurträger verlegt werden können.In a solution according to the invention, the track carriers and the launching carrier are connected to one another via intermediate adapters. Through the use of intermediate adapters, it is possible that the launching carrier and track carrier no longer have to be adapted to each other and can be laid with a launching carrier different track carrier.

Es hat sich als vorteilhaft herausgestellt, wenn die Spurträger und die Zwischenadapter lösbar miteinander verbunden sind. Beispielsweise können die Spurträger in den Zwischenadapter eingehängt werden. Das bietet den Vorteil, dass die verschiedenen Elemente unabhängig voneinander transportiert werden und platzsparend auf entsprechenden Verladefahrzeugen angeordnet werden können. Durch das Einhängen können Spurträger und Zwischenadapter am Verlegeort schnell und variabel miteinander verbunden und dann über Mittel derart fixiert werden, dass sich eine feste Verbindung ergibt und sich die Elemente nicht mehr gegeneinander verschieben können.It has proven to be advantageous if the track carrier and the intermediate adapter are detachably connected to each other. For example, the track carrier can be hung in the intermediate adapter. This offers the advantage that the different elements are transported independently of each other and space-saving on appropriate loading vehicles can be arranged. By hanging track carrier and intermediate adapter can be quickly and variably connected to each other at the installation and then fixed by means such that there is a firm connection and the elements can no longer move against each other.

Des Weiteren hat es sich als positiv herausgestellt, wenn die Zwischenadapter und der Vorbauträger lösbar miteinander verbunden sind. Die beiden Elemente können dabei auch über Laufrollen miteinander verbunden sein, so dass sich der Zwischenadapter über die Laufrollen auf dem Vorbauträger abstützen kann. Bevorzugt weist der Vorbauträger dafür Führungen auf, in denen die Rollen des Zwischenadapters geführt sind. Über die Rollen kann der Zwischenadapter, insbesondere mit verbundenen Spurträgern, möglichst einfach über den bereits verlegten Vorbauträger zum jenseitigen Ufer geschoben werden. In einer alternativen Ausgestaltungsform kann auch der Vorbauträger Rollen aufweisen, die in entsprechenden Führungen am Zwischenadapter geführt sind.Furthermore, it has been found to be positive if the intermediate adapter and the front-mounting are releasably connected to each other. The two elements can also be connected via rollers with each other, so that the intermediate adapter can be supported on the Vorbauträger on the rollers. Preferably, the pre-construction carrier for guides on, in which the rollers of the intermediate adapter are guided. About the roles of the intermediate adapter, in particular with connected track carriers, as simple as possible to be pushed over the already laid submersible beam to the other side shore. In an alternative embodiment, the launching support may also comprise rollers which are guided in corresponding guides on the intermediate adapter.

Weiterhin hat es sich als vorteilhaft erwiesen, wenn der Zwischenadapter räumlich zwischen bzw. zumindest abschnittsweise zwischen dem Vorbauträger und dem Spurträger angeordnet ist. Dabei kann der Zwischenadapter in einer ersten Ausgestaltungsform derart ausgebildet sein, dass der Zwischenadapter zwei gegenüberliegende Spurträger miteinander verbindet. Beide gegenüberliegenden Spurträger werden dabei über einen gemeinsamen Zwischenadapter mit dem Vorbauträger verbunden, so dass beim Verlegen der Brücke die Spurträger voneinander abhängig zum jenseitigen Ufer bewegt werden können. Der Zwischenadapter verläuft in dieser Ausgestaltungsform im Wesentlichen, jedoch nicht darauf beschränkt, oberhalb des Vorbauträgers. Er schließt damit in vertikaler Richtung bündig mit den Spurträgern ab und bildet zusammen mit den Spurträgern die Fahrbahn der Brücke. Der Zwischenadapter fungiert zudem insbesondere als Mittenabdeckung zwischen den Spurträgern.Furthermore, it has proved to be advantageous if the intermediate adapter is arranged spatially between or at least in sections between the prealcarrier and the track carrier. In this case, the intermediate adapter may be formed in a first embodiment such that the intermediate adapter connects two opposing track carrier each other. Both opposing track carriers are connected via a common intermediate adapter with the launching carrier, so that when laying the bridge, the track carriers can be moved from each other depending on the otherworldly shore. The intermediate adapter extends in this embodiment substantially, but not limited, above the preallocator. He concludes so in the vertical direction flush with the track carriers and forms along with the track carriers the carriageway of the bridge. The intermediate adapter also acts in particular as a center cover between the track carriers.

In einer anderen Ausführungsform können mehrere Zwischenadapter zum Einsatz kommen. Auf jeder Seite des Vorbauträgers kann ein Zwischenadapter angeordnet sein. Beispielsweise kann zwischen dem Vorbauträger und jedem Spurträger ein einzelner Zwischenadapter angeordnet sein, so dass bei jeweils zwei Spurträgern pro Abschnitt auch zwei Zwischenadapter verwendet werden können. Die Spurträger können in diesem Fall unabhängig voneinander bewegt bzw. verlegt werden. Damit sind die gegenüberliegenden Spurträger nicht gekoppelt und daher unabhängig voneinander beweg- bzw. verlegbar.In another embodiment, several intermediate adapters may be used. An intermediate adapter can be arranged on each side of the apron carrier. For example, a single intermediate adapter can be arranged between the front carrier and each track carrier, so that two intermediate carriers can also be used per two track carriers per section. The track carriers can be moved or moved independently of each other in this case. Thus, the opposite track carrier are not coupled and therefore independently movable or can be laid.

In einer Ausgestaltungsform bilden die Spurträger und die Zwischenadapter die Fahrbahn, bevorzugt bilden die Spurträger, die Zwischenadapter und der Vorbauträger die Fahrbahn. Dies kann zum Beispiel der Fall sein, wenn jeder Spurträger mit einem einzelnen Zwischenadapter verbunden ist. Die fahrbahnbildenden Komponenten schließen dabei derart bündig miteinander ab, dass von ihnen eine im Wesentlichen geschlossene Fahrbahndecke gebildet wird.In one embodiment, the track carrier and the intermediate adapter form the roadway, preferably the track carrier, the intermediate adapter and the Vorbauträger form the roadway. This may be the case, for example, when each track carrier is connected to a single intermediate adapter. The roadway-forming components are flush with each other in such a way that a substantially closed road surface is formed by them.

Die Spurträger weisen vorzugsweise einen Ober- und einen Untergurt auf, wobei Ober- und Untergurt über Streben miteinander verbunden sind und somit der Spurträger über die Streben verstärkt sein kann. Der Obergurt bildet vorzugsweise einen Teil der Fahrbahn. In einer Ausgestaltungsform weisen die Spurträger einen im Wesentlichen U-förmigen Querschnitt auf.The track carriers preferably have an upper and a lower belt, wherein the upper and lower belts are connected to one another via struts and thus the track carrier can be reinforced by the struts. The upper belt preferably forms part of the roadway. In one embodiment, the track carriers have a substantially U-shaped cross-section.

Durch die Variabilität der Zwischenadapter kann für unterschiedliche Spurträger weiterhin derselbe Vorbauträger verwendet werden. Des Weiteren können neben verschiedenen Spurträgern auch verschiedene Zwischenadapter verwendet werden. So hat es sich als vorteilhaft erwiesen, wenn breitere Zwischenadapter mit schmaleren Spurträgern oder schmalere Zwischenadapter mit breiteren Spurträgern eingesetzt werden. Die Erfindung ist jedoch nicht auf diese Ausführungen beschränkt, sondern je nach Anforderungen, die an die Brücke gestellt werden, können verschiedene Zwischenadapter mit verschiedenen Spurträgern verwendet werden.Due to the variability of the intermediate adapter, the same front-end carrier can continue to be used for different track carriers. Furthermore, in addition to different track carriers and various intermediate adapter can be used. So it has proven to be advantageous if wider intermediate adapter be used with narrower track carriers or narrower intermediate adapter with wider track carriers. However, the invention is not limited to these embodiments, but depending on the requirements that are placed on the bridge, various intermediate adapter can be used with different track carriers.

Der Vorbauträger muss aufgrund der anpassbaren Zwischenadapter nicht an die unterschiedlichen Spurträger angepasst sein bzw. müssen die Spurträger nicht an den Vorbauträger angepasst sein. Die Seite des Zwischenadapters, die mit dem Vorbauträger im Eingriff steht, kann daher in konstruktiver Hinsicht an den Vorbauträger angepasst sein. Die Seite des Zwischenadapters, die mit dem Spurträger im Eingriff steht, kann an den entsprechenden Spurträger angepasst sein. So hat es sich beispielsweise als vorteilhaft erwiesen, wenn Zwischenadapter gleiche Verbindungsstellen für den Vorbauträger und unterschiedliche Verbindungsstellen für die Spurträger aufweisen. Damit bietet die hier beschriebene zerlegbare Spurträgerbrücke auch die Möglichkeit, bereits bekannte Brücken, die zum Beispiel mit einem Vorbauträger verlegt werden, umzurüsten oder Spurträger einer Brücke mit einem Vorbauträger einer anderen Brücke zu kombinieren.Due to the adaptable intermediate adapter, the pre-body carrier does not have to be adapted to the different track carriers or the track carriers do not have to be adapted to the pre-body carrier. The side of the intermediate adapter which engages with the launching girder may therefore be structurally adapted to the launching girder. The side of the intermediate adapter engaged with the track carrier may be adapted to the corresponding track carrier. For example, it has proved to be advantageous if intermediate adapters have identical connection points for the launching carrier and different connection points for the track carriers. Thus, the demountable track carrier bridge described here also offers the possibility to convert already known bridges, which are laid, for example, with a launching carrier, or to combine track carriers of one bridge with a front carrier of another bridge.

Besonders vorteilhaft ist es, wenn Vorbauträger, Zwischenadapter und Spurträger in Ebenen, die senkrecht zur Verlegerichtung ausgerichtet sind, in einzelne Vorbauträger-, Zwischenadapter bzw. Spurträgerabschnitte unterteilt sind. Besonders bevorzugt ist die Länge der einzelnen Abschnitte in Verlegerichtung im Wesentlichen ähnlich.It is particularly advantageous if the substructure carrier, intermediate adapter and track carrier are subdivided into individual pre-carrier, intermediate adapter or track carrier sections in planes which are aligned perpendicular to the laying direction. Particularly preferably, the length of the individual sections in the laying direction is substantially similar.

Die Brücke kann durch eine Verlegevorrichtung mit einem Verlegearm verlegt werden. Da die große Variabilität der Brücke auf den unterschiedlichen Ausführungen der Zwischenadapter und Spurträger beruht, können mit demselben Verlegearm bei gleichem Vorbauträger unterschiedliche Zwischenadapter und/oder Spurträger verlegt werden.The bridge can be laid by a laying device with a laying arm. Since the great variability of the bridge is based on the different versions of the intermediate adapter and track carrier, can with the same Laying low at the same substructure carrier different intermediate adapter and / or track carrier are laid.

Der Verlegearm ist lösbar mit dem Vorbauträger verbunden. Dabei hat es sich als vorteilhaft herausgestellt, wenn der Verlegearm und der Vorbauträger über Rollen miteinander verbunden sind. Besonders bevorzugt weist der Verlegearm dabei Rollen auf, die in entsprechenden Führungen am Vorbauträger geführt sind. Ferner kann der Vorbauträger Rollen und der Verlegearm entsprechende Führungen aufweisen.The laying arm is detachably connected to the prefabricated support. It has been found to be advantageous if the laying arm and the launching carrier are connected to each other via rollers. Particularly preferably, the laying arm has rollers which are guided in corresponding guides on the launching carrier. Furthermore, the pre-conveyor rollers and the laying arm may have corresponding guides.

Der Verlegearm weist mindestens einen, bevorzugt mindestens zwei Antriebe auf. Der erste Antrieb wirkt dabei auf den Vorbauträger und kann diesen bevorzugt, jedoch nicht einschränkend, linear in Verlegerichtung bewegen. Der zweite Antrieb wirkt auf den bzw. die Zwischenadapter und kann diese bevorzugt, jedoch nicht einschränkend, linear in Verlegerichtung bewegen. Besonders wenn die Zwischenadapter derart ausgestaltet sind, dass einzelne Zwischenadapter für jeden Spurträger eingesetzt werden, hat es sich als vorteilhaft herausgestellt, wenn der erste Antrieb auf den einen Zwischenadapter und der zweite Antrieb auf den anderen Zwischenadapter unabhängig voneinander sind. Das bietet den Vorteil, dass beide Seiten der Brücke unterschiedlich schnell verlegt werden können, was zu einer Reduzierung der gesamten Verlegezeit führen kann.The laying arm has at least one, preferably at least two drives. The first drive acts on the launching girder and can move it preferably, but not restrictively, linearly in the laying direction. The second drive acts on the intermediate adapter (s) and can move it preferably, but not restrictively, linearly in the laying direction. Particularly when the intermediate adapter are designed such that individual intermediate adapter are used for each track carrier, it has been found to be advantageous if the first drive on the one intermediate adapter and the second drive on the other intermediate adapter are independent of each other. This offers the advantage that both sides of the bridge can be laid at different speeds, which can lead to a reduction in the total laying time.

Des Weiteren ist es möglich, dass für die Zwischenadapter und den Vorbauträger nur ein Antrieb verwendet wird. Das ist insbesondere denkbar, da der Vorbauträger im Wesentlichen zuerst verlegt wird und der Antrieb beim Verlegen der Zwischenadapter für den Vorbauträger nicht mehr genutzt wird. Ferner ist es zudem denkbar, dass ein Antrieb oder mehrere Antriebe, insbesondere zum Verlegen der Zwischenadapter, am Verlegearm angeordnet sind oder auch an den Zwischenadaptern selbst.Furthermore, it is possible that only one drive is used for the intermediate adapter and the Vorbauträger. This is in particular conceivable, since the launching girder is essentially laid first and the drive is no longer used for laying the intermediate adapter for the launching girder. Furthermore, it is also conceivable that a drive or a plurality of drives, in particular for Laying the intermediate adapter, are arranged on the laying arm or on the intermediate adapters themselves.

Um die Brücke an ihren Einsatzort zu bringen, kann sie auf einem Verlegefahrzeug transportiert werden. Die entsprechende Verlegevorrichtung kann ebenfalls am Verlegefahrzeug angeordnet sein. Auf dem Verlegefahrzeug können verschiedene Spurträger, verschiedene Vorbauträger und verschiedene Zwischenadapter angeordnet sein. Besonders bei großen Spannweiten ist es jedoch notwendig, dass zudem Teile der Brücke auch auf anderen Fahrzeugen transportiert werden können und am Verlegeort zusammengesetzt werden.In order to bring the bridge to its place of use, it can be transported on a laying vehicle. The corresponding laying device can also be arranged on the laying vehicle. On the laying vehicle, different track carrier, different Vorbauträger and various intermediate adapter can be arranged. Especially with large spans, however, it is necessary that also parts of the bridge can be transported on other vehicles and assembled at the installation site.

Es hat sich dabei als vorteilhaft erwiesen, wenn mehrere Zwischenadapter, insbesondere Zwischenadapter mit verschiedenen Anschlussstellen für verschiedene Spurträger, zusammen mit oder auch ohne entsprechende Spurträger als Set mitgeführt werden. Dadurch erhöht sich zwar die Anzahl der zu transportierenden Teile, jedoch kann dadurch erst am Einsatzort entschieden werden, welche Zwischenadapter und welche Spurträger für die Brücke verwendet werden. Dies stellt insbesondere dann einen großen Vorteil da, wenn Militäroperationen in unbekanntem Gelände durchgeführt werden sollen.It has proven to be advantageous if several intermediate adapter, in particular intermediate adapter with different connection points for different track carrier, together with or without corresponding track carrier are included as a set. Although this increases the number of parts to be transported, it can only be decided at the place of use which intermediate adapters and which track carriers are used for the bridge. This is a great advantage, especially if military operations are to be conducted in unfamiliar terrain.

Für das Verlegen der Brücke hat es sich wie bereits beschrieben als vorteilhaft erwiesen, wenn zunächst der Vorbauträger verlegt wird. Das geschieht, indem der Vorbauträger bzw. die einzelnen Vorbauträgerabschnitte sukzessive durch einen entsprechenden Antrieb über den zu überbrückenden Abschnitt verfahren werden. Dabei können abhängig von der benötigten Brückenlänge mehrere der einzelnen Vorbauträgerabschnitte aneinander gereiht werden. Das vordere Ende des Vorbauträgers wird, sobald es das jenseitige Ufer erreicht, an diesem abgelegt und überspannt damit den gesamten zu überspannenden Abschnitt. Die einzelnen Abschnitte werden über Mittel sukzessive miteinander verbunden, so dass ein möglichst stabiler Vorbauträger entsteht, der, sobald er am jenseitigen Ufer abgelegt wurde, im Wesentlichen nicht mehr verschiebbar ist.As already described, it has proven to be advantageous for the laying of the bridge when firstly the launching beam is laid. This is done by the preliminary support or the individual prealigner sections are successively moved by a corresponding drive over the section to be bridged. In this case, depending on the required bridge length, several of the individual substructure support sections can be lined up. As soon as it reaches the other side of the bank, the front end of the pre-construction girder is deposited there, thus spanning the entire section to be spanned. The individual sections are successively interconnected via funds, so that the most stable possible launching carrier, which, as soon as it was deposited on the other side shore, is essentially no longer displaceable.

Der oder die Zwischenadapter werden dann mit dem Vorbauträger verbunden. Es ist zudem möglich, dass die Spurträger bereits davor mit den entsprechenden Zwischenadaptern verbunden werden. Über einen bzw. auch mehrere Antriebe werden dann die Zwischenadapter, wahlweise mit Spurträgern, über den zu überbrückenden Abschnitt verfahren. Dabei kann der Vorbauträger als Abstützung für die Zwischenadapter dienen. Auch die Zwischenadapterabschnitte bzw. die Spurträgerabschnitte können beim Verlegen, insbesondere in Verlegerichtung analog der Vorbauträgerabschnitte sukzessive aneinandergereiht werden, so dass die Brücke sukzessive in Verlegerichtung wächst, bis der erste Zwischenadapterabschnitt bzw. der erste Spurträgerabschnitt das jenseitige Ufer erreicht. Haben die Zwischenadapter und die Spurträger das jenseitige Ufer erreicht, so sind Zwischenadapter und Spurträger im Wesentlichen nicht mehr verschiebbar.The one or more intermediate adapters are then connected to the front carrier. It is also possible that the track carriers are already connected before with the corresponding intermediate adapters. About one or more drives then the intermediate adapter, optionally traversed with track carriers, over the section to be bridged. Here, the launching support can serve as a support for the intermediate adapter. The intermediate adapter sections or the track carrier sections can also be successively strung together during installation, in particular in the laying direction, so that the bridge grows successively in the laying direction until the first intermediate adapter section or the first track carrier section reaches the otherworldly bank. Have the intermediate adapter and the track carrier reaches the other side bank, so intermediate adapter and track carrier are essentially no longer displaceable.

Besonders bevorzugt werden die einzelnen Vorbauträger-, Zwischenadapter- und Spurträgerabschnitte auch in Verlegerichtung miteinander verbunden. Das bedeutet, dass beispielsweise der erste Vorbauträgerabschnitt am hinteren Ende mit dem vorderen Ende des zweiten Vorbauträgerabschnitts verbunden wird. Analoges gilt für die darauf folgenden Abschnitte sowie auch für die Spurträgerabschnitte und die Zwischenadapterabschnitte.Particularly preferably, the individual Vorbauträger-, Zwischenadapter- and track carrier sections are also connected together in the laying direction. That is, for example, the first front end support portion is connected to the front end of the second front end support portion at the rear end. The same applies to the subsequent sections and also to the track carrier sections and the intermediate adapter sections.

Das in Fig. 1 gezeigte Ausführungsbeispiel betrifft eine zerlegbare Spurträgerbrücke, bei der zwei gegenüberliegende Spurträger über einen Zwischenadapter miteinander verbunden sind. Dabei ist ein Querschnitt durch die Brücke mit einem entsprechenden Verlegearm 8 dargestellt. Die Darstellung der Fig. 1 ist achsensymmetrisch, weshalb alle Bezugszeichen, die nur auf einer Seite dargestellt sind, sich gleichzeitig auch auf das entsprechende Teil der anderen Seite beziehen.This in Fig. 1 embodiment shown relates to a collapsible track carrier bridge, in which two opposite track carrier are connected to each other via an intermediate adapter. In this case, a cross section through the bridge with a corresponding laying arm 8 is shown. The presentation of the Fig. 1 is axisymmetric, which is why all reference numerals, which are shown only on one side, at the same time refer to the corresponding part of the other side.

Die beiden Spurträger 1, 2 sind links bzw. rechts vom Vorbauträger 14 angeordnet und bilden zusammen mit dem Zwischenadapter 7 die Fahrbahn 19. Die Spurträger 1, 2 weisen dabei jeweils einen Obergurt 3, 5 und einen Untergurt 4, 6 auf.The two track carriers 1, 2 are arranged on the left or right of the launching carrier 14 and together with the intermediate adapter 7 form the roadway 19. The track carriers 1, 2 each have a top flange 3, 5 and a bottom flange 4, 6.

Im oberen Bereich sind die Spurträger 1, 2 mittels der Verbindungsstellen 17, 18 mit einem Zwischenadapter 7 verbunden und fixiert, so dass sie sich im Wesentlichen nicht relativ zueinander bewegen können. Die Verbindungsstellen des Zwischenadapters sind dabei an die Spurträger angepasst, so dass es ermöglicht wird, dass die Spurträger 1, 2 nicht an den Vorbauträger 14 und zudem auch nicht an den Verlegearm 8 angepasst sein müssen. Dies führt zu einer großen Variabilität der Brücke, da beispielsweise abhängig vom Einsatzgebiet sowohl breite als auch schmale Spurträger mit demselben Vorbauträger verbunden werden können.In the upper area, the track carriers 1, 2 are connected and fixed by means of the connection points 17, 18 with an intermediate adapter 7, so that they can not move relative to one another substantially. The connection points the intermediate adapter are adapted to the track carrier, so that it is possible that the track carrier 1, 2 need not be adapted to the Vorbauträger 14 and also not to the laying arm 8. This leads to a large variability of the bridge, since, for example, both wide and narrow track carrier can be connected to the same Vorbauträger depending on the application.

Da zum Verlegen der Brücke aus Gewichtsgründen ein Vorbauträger 14 benötigt wird, kann sich der Zwischenadapter 7 auf dem Vorbauträger 14 abstützen. Der Zwischenadapter 7 weist dafür am unteren Ende an jeder Seite Laufrollen 13 auf, die in entsprechenden Führungen 12 des Vorbauträgers 14 geführt sind. Über die Laufrollen 13 kann sich der Zwischenadapter 6 mit den verbundenen Spurträgern 1, 2 auf dem Vorbauträger 14 abstützen und zudem in Verlegerichtung V bewegt werden.Since for laying the bridge for weight reasons, a launching beam 14 is required, the intermediate adapter 7 can be supported on the prealbox 14. The intermediate adapter 7 has for this purpose at the lower end on each side rollers 13, which are guided in corresponding guides 12 of the prealbox 14. About the rollers 13, the intermediate adapter 6 can be supported with the associated track carriers 1, 2 on the prealbox 14 and also moved in the laying direction V.

Unterhalb des Vorbauträgers 14 ist der Verlegearm 8 angeordnet. Dieser weist Laufrollen 9 auf, die in entsprechenden Führungen 15 des Vorbauträgers 14 geführt sind. Beim Verlegen des Vorbauträgers 14 kann dieser über die Rollen 9 abgestützt und somit relativ zum Verlegearm bewegt werden. Um den Vorbauträger 14 und den Zwischenadapter 14 in Verlegerichtung V zu bewegen, verfügt der Verlegearm 8 in dieser Ausgestaltungsform über zwei Antriebe 10 und 11. Der Antrieb 11 steht dabei mit dem Vorbauträger 14 im Eingriff und kann diesen bewegen. Der Antrieb 10 steht mit den am Zwischenadapter 7 angeordneten Führungen 16, dicht hinter den Laufrollen 13, im Eingriff. Durch den Antrieb 10 kann der Zwischenadapter 7, insbesondere zusammen mit den Spurträgern 1, 2, ebenfalls in Verlegerichtung V bewegt werden.Below the apron carrier 14 of the laying arm 8 is arranged. This has rollers 9, which are guided in corresponding guides 15 of the prealbox 14. When laying the apron carrier 14 this can be supported on the rollers 9 and thus moved relative to the laying arm. In order to move the prealplate 14 and the intermediate adapter 14 in the laying direction V, the laying arm 8 in this embodiment has two drives 10 and 11. The drive 11 is engaged with the prealplate 14 and can move it. The drive 10 is connected to the arranged on the intermediate adapter 7 guides 16, just behind the rollers 13, in engagement. By the drive 10, the intermediate adapter 7, in particular together with the track carriers 1, 2, are also moved in the laying direction V.

Da zunächst der Vorbauträger 14 verlegt wird und sich der Zwischenadapter 7 dann über die Rollen auf dem bereits verlegten Vorbauträger 14 abstützt, kommt zunächst der Antrieb 11 und im Anschluss der Antrieb 10 zum Einsatz.Since first of the prealbox 14 is laid and the intermediate adapter 7 is then supported on the rollers on the already laid prealbox 14, first comes the drive 11 and then the drive 10 is used.

In Fig. 2 ist eine entsprechende Ausgestaltungsform der Spurträgerbrücke mit zwei einzelnen Zwischenadaptern 21, 22 dargestellt. Dadurch muss der rechte Zwischenadapter 21 mit seiner Verbindungsstelle 118 entsprechend nur an den rechten Spurträger 101 angepasst sein. Der Spurträger 101 kann dabei beispielsweise zunächst in den rechten Zwischenadapter eingehängt werden und dann fixiert werden. Analoges gilt entsprechend auch für die andere Seite. Im Gegensatz zum Ausführungsbeispiel der Fig. 1, kann die zerlegbare Spurträgerbrücke damit noch variabler Ausgestaltet werden, da es zudem auch denkbar ist, dass auf der linken und auf der rechten Seite verschiedene Spurträger 101, 102 eingesetzt werden können. Zudem bildet in dieser Ausführungsform auch der Vorbauträger einen Teil der Fahrbahn 119, so dass die Brücke insgesamt eine niedrigere Kontur aufweist.In Fig. 2 a corresponding embodiment of the track carrier bridge with two individual intermediate adapters 21, 22 is shown. As a result, the right intermediate adapter 21 with its connection point 118 must be adapted accordingly only to the right-hand track carrier 101. The track carrier 101 can be hung, for example, first in the right intermediate adapter and then fixed. The same applies analogously for the other side. In contrast to the embodiment of Fig. 1 , the demountable track carrier bridge can thus be made even more variable, since it is also conceivable that on the left and on the right side different track carriers 101, 102 can be used. In addition, in this embodiment, the prealigner forms part of the roadway 119, so that the bridge has a lower overall contour.

Beide Spurträger 101, 102 weisen jeweils einen Obergurt 103, 106 und einen Untergurt 104, 106 auf. Die Obergurte 103, 105 der Spurträger 101, 102 sind dabei entsprechend als Fahrbahnabschnitte ausgebildet und bilden zusammen mit den Zwischenadaptern 21, 22 und dem Vorbauträger 14 eine im Wesentlichen durchgängige Fahrbahn 119. Bei den Spurträgern 101, 102 kann, jedoch muss es sich nicht um dieselben Spurträger 1, 2 handeln, die in Fig. 1 dargestellt sind, da durch die variable Ausgestaltung der Verbindungsstellen 117, 118 verschiedene Spurträger 1, 2, 101, 102 mit den Zwischenadaptern 21, 22, 7 verbunden werden können.Both track carriers 101, 102 each have a top flange 103, 106 and a bottom flange 104, 106. The upper belts 103, 105 of the track carriers 101, 102 are correspondingly designed as roadway sections and, together with the intermediate adapters 21, 22 and the launching carrier 14, form a substantially continuous roadway 119. The track carriers 101, 102 can, but do not have to the same track carrier 1, 2 act in Fig. 1 are represented, since by the variable configuration of the connection points 117, 118 different track carrier 1, 2, 101, 102 can be connected to the intermediate adapters 21, 22, 7.

Die Zwischenadapter 21, 22 weisen jeweils eine Laufrolle 23 auf, über welche sie mit dem Vorbauträger 14 verbunden sind. Die Laufrollen 116 sind dafür in entsprechenden Führungen 112 des Vorbauträgers 14 geführt. Zudem sind in diesem Ausführungsbeispiel auch am Vorbauträger 14 Laufrollen 24 angeordnet, die mit den Führungen 20 der Zwischenadapter 21, 22 im Eingriff stehen. Da die Zwischenadapter 21, 22 in dieser Ausführungsform getrennt sind, müssen entsprechend an jedem der Zwischenadapter 21, 22 zwei Lagerpunkte bzw. Verbindungsstellen mit dem Vorbauträger vorgesehen sein, um die entsprechenden Kräfte und Momente aufzunehmen.The intermediate adapter 21, 22 each have a roller 23, via which they are connected to the prealbox 14. The rollers 116 are for in corresponding guides 112 of the launching truss 14 out. In addition, in this exemplary embodiment, rollers 24 are arranged on the prealplate 14, which are in engagement with the guides 20 of the intermediate adapters 21, 22. Since the intermediate adapters 21, 22 are separated in this embodiment, corresponding to each of the intermediate adapters 21, 22, two bearing points or connection points must be provided with the Vorbauträger to accommodate the corresponding forces and moments.

Zum Verlegen der Brücke müssen sowohl Vorbauträger als auch Zwischenadapter mit Spurträgern in Verlegerichtung V bewegt werden. Der am Verlegearm 8 angeordnete Antrieb 10 steht dabei mit den Führungen 116 der Zwischenadapter 21, 22 im Eingriff. Durch die geteilte Ausführung des Zwischenadapters 21, 22, kann der Antrieb 10 auch asymmetrisch sein. Das bedeutet, dass z. B. die eine Seite der Anordnung unabhängig von der anderen Seite bewegt und verlegt werden kann. Dadurch können die Spurträger der linken und die der rechten Seite unabhängig voneinander bewegt werden, was auf Grund des möglichen Parallelbetriebs zu einer Verkürzung der gesamten Verlegezeit führt.To lay the bridge, both front-end girders and intermediate adapters with track girders must be moved in the laying direction V. The arranged on the laying arm 8 drive 10 stands with the guides 116 of the intermediate adapter 21, 22 in engagement. Due to the split design of the intermediate adapter 21, 22, the drive 10 may also be asymmetrical. This means that z. B. the one side of the arrangement can be moved and moved independently of the other side. As a result, the track carriers of the left and the right side can be moved independently, resulting in a shortening of the total laying time due to the possible parallel operation.

Der Vorgang des Verlegens wird am Beispiel des Vorbauträgers 14 im Folgenden anhand der Fig. 3a bis 3d näher erläutert. Der Verlegearm 8 ist am Verlegefahrzeug 100 angeordnet, welches am Ufer eines zu überbrückenden Abschnitts 200 steht. Der erste Abschnitt 14.1 des Vorbauträgers 14 wird durch den Verlegearm 8 in Richtung V bewegt. Sukzessive werden dann weitere Abschnitte 14.2, 14.3 an den ersten Abschnitt 14.1 angereiht und am jeweils vorherigen Abschnitt befestigt. Sobald der erste Abschnitt 14.1 des Vorbauträgers 14 das jenseitige Ufer 201 erreicht, wird der Vorbauträger wie in Fig. 3d dargestellt, abgelegt und ist dann im Wesentlichen nicht mehr verschiebbar. Das hinterste Ende des Vorbauträgers 14 verbleibt zunächst am Verlegearm 8, da es als Stütze für die Zwischenadapter 7, 21, 22 dient, die im Anschluss daran über den Vorbauträger 14 mittels des Antriebs 10 ebenfalls zum jenseitigen Ufer 201 vorgeschoben werden und sich dabei über Rollen auf dem Vorbauträger abstützen.The process of laying is the example of the pre-body 14 hereinafter with reference to the Fig. 3a to 3d explained in more detail. The laying arm 8 is arranged on the laying vehicle 100, which stands on the bank of a section 200 to be bridged. The first section 14.1 of the launching girder 14 is moved by the laying arm 8 in the direction V. Successive sections 14.2, 14.3 are then added to the first section 14.1 and attached to the respective previous section. As soon as the first section 14.1 of the pre-launching carrier 14 reaches the other side bank 201, the pre-launching carrier becomes as in FIG Fig. 3d displayed, stored and then essentially not be moved. The rearmost end of the apron carrier 14 initially remains on the laying arm 8, since it serves as a support for the intermediate adapter 7, 21, 22, the following are also advanced to the otherworldly bank 201 via the launching superstructure 14 by means of the drive 10 and thereby supported by rollers on the launching girder.
