Description

Die Erfindung betrifft eine zerlegbare Brücke nach dem Oberbegriff des Anspruchs 1.The invention relates to a collapsible bridge according to the preamble of claim 1.

Die DE-C-1 207 948 ergänzt durch den M.A.N-Firmenprospekt "Kurzbrücke - Short-Span Bridge - Puente Corto" bildet den nächstliegenden Stand der Technik. Die Brückenelemente der DE-C-1 207 948 verfügen über zwei "Wirkstellungen", nämlich einen Transportzustand und einen Einbauzustand, wobei der Transportzustand ggf. auch für die Aufnahme von geringeren Lasten geeignet ist und u.U. auch einen wirksamen Einbauzustand ergeben könnte.DE-C-1 207 948 supplemented by the M.A.N company brochure "Short Bridge - Short Span Bridge - Puente Corto" forms the closest prior art. The bridge elements of DE-C-1 207 948 have two "active positions", namely a transport state and an installation state, the transport state possibly also being suitable for the absorption of lower loads and possibly. could also result in an effective installation condition.

Da es also möglich ist bei den Brückenelementen nach der o.a. Druckschrift diese im Transportzustand einzubauen (z.B. für geringe Lasten), ergeben sich dort zwei (also mehrere) mögliche Einbauzustände, in denen die so gebildete Brücke für die Aufnahme von Lasten geeignet ist.Since it is possible for the bridge elements according to the above In order to install this document in the transport state (e.g. for low loads), there are two (i.e. several) possible installation states in which the bridge thus formed is suitable for accepting loads.

Aus der DE-C-3138853 (EP-A-0075671 ) ist eine zerlegbare Brücke bekannt, die aus zusammenkuppelbaren Brückenelementen gleicher Höhe besteht. Diese Brücke kann sehr schnell aufgebaut werden. Zum Transport einer 40 Meterbrücke sind aber immer noch mehrere Fahrzeuge notwendig.From DE-C-3138853 (EP-A-0075671) a dismountable bridge is known which consists of interconnectable bridge elements of the same height. This bridge can be built very quickly. However, several vehicles are still required to transport a 40-meter bridge.

Aus der GB-A-2155979 ist eine zerlegbare Brücke bekannt, die aus mehreren zusammenkuppelbaren Brückenelementen besteht. Die Brückenelemente enthalten eine oder mehrere Fahrbahnplatten, Untergurte und Streben. Diese Brücke bildet den Oberbegriff des Anspruchs 1. Die Brückenelemente sind entweder als Zentralelemente mit horizontal verlaufender Fahrbahn oder als Rampenelemente mit geneigt verlaufender Fahrbahn ausgelegt. Rampenelemente können nicht als Zentralelemente verwendet werden, so daß beim Transport der Brücke relativ viele Teile mitzuführen sind.From GB-A-2155979 a dismountable bridge is known, which consists of several interconnectable bridge elements. The bridge elements contain one or more road slabs, lower chords and struts. This bridge forms the preamble of claim 1. The bridge elements are designed either as central elements with a horizontally running lane or as ramp elements with an inclined lane. Ramp elements cannot be used as central elements, so that a relatively large number of parts must be carried when transporting the bridge.

Aufgabe der Erfindung ist es, eine Brücke, insbesondere für militärische Zwecke, vorzugschlagen, die möglichst wenige Fahrzeuge benötigt und in ihrer Länge variabel aufstellbar ist.The object of the invention is to propose a bridge, in particular for military purposes, which requires as few vehicles as possible and which is variable in its length.

Diese Aufgabe wird erfindungsgemäß gelöst von einer Brücke mit den Merkmalen des Anspruchs 1. Ausführungen der Erfindung und ein Verlegefahrzeug mit dieser Brücke sind Gegenstände von Ansprüchen 2 bis 10.This object is achieved according to the invention by a bridge with the features of claim 1. Embodiments of the invention and a laying vehicle with this bridge are the subject of claims 2 to 10.

Erfindungsgemäß ist ein Fachwerk aus Streben und Untergurten vorgesehen, mit dem sich die einzelnen Brückenelemente in ihrer Höhe verstellen lassen - symmetrisch -, so daß Fahrbahn und Untergurt parallel verlaufen, oder unsymmetrisch, so daß die Fahrbahn nicht parallel zum Untergurt verläuft. Damit lassen sich Brücken herstellen, bei denen die Fahrbahn und der Untergurt oder eines beider Bauelemente einen bogenförmigen Verlauf nimmt, sodaß die Brücke in ihrer Mitte höher ist als an ihren Enden. So können z.B. die Fahrbahnplatten einen Bogen und die Untergurte die dazugehörende Sehne bilden. Durch die verstellbare Höhe kann die Brücke dem Momentenverlauf angepaßt werden. Die erfindungsgemäße Gestaltung der Brückenelemente führt dazu, daß der Untergurt und die Diagonalstreben beim Transport auf sehr kleinen Raum zusammengefaltet werden können. Das geringe Gewicht und die kleinen Transportabmessungen erlauben im Fall einer Panzerbrücke die Gesamtlänge von ca. 40 Metern mit einem Fahrzeug zu transportieren. Da alle Brückenabschnitte gleich und auf einem Fahrzeug sind, läßt sich das Bauen und Verlegen von verschiedenen Brückenlängen gut automatisieren.According to the invention, a framework of struts and lower chords is provided with which the height of the individual bridge elements can be adjusted - symmetrically - so that the carriageway and lower chord run parallel, or asymmetrically so that the carriageway does not run parallel to the lower chord. This makes it possible to manufacture bridges in which the roadway and the lower flange or one of both components has an arcuate course, so that the bridge is higher in the middle than at its ends. For example, the pavement slabs form an arch and the lower chords form the associated tendon. Due to the adjustable height, the bridge can be adapted to the torque curve. The design of the bridge elements according to the invention means that the lower flange and the diagonal struts can be folded together during transport in a very small space. The low weight and the small transport dimensions allow the total length of approx. 40 meters to be transported by vehicle in the case of an armored bridge. Since all bridge sections are the same and on one vehicle, the building and laying of different bridge lengths can be easily automated.

Die erfindungsgemäße Brücke hat folgende Vorteile:

  • - wenig und kleine Ersatzteile
  • - wenig Windangriffsfläche
  • - wenig Beschußfläche
  • - große Variabilität, d.h., es können entweder eine sehr lange oder mehrere kurze Brücken gleichzeitig von einem Fahrzeug gebaut werden
  • - bis 45 Meter kein Vorbauträger nötig
  • - geringes Gewicht
  • - geringes Transportvolumen
  • - bessere Brückensicht des Panzerfahrers bei Anfahrt auf die Brücke
  • - Teile können von Hand ausgewechselt werden und auch als Ersatz mitgeführt werden (in einem Beispiel wiegt das Teleskop 56 kg, ein Untergurtabschnitt 150 kg, eine Kupplung 50 kg und eine Rampe 200 kg)
  • - höhere Eigenfrequenz dank steifer und kleinerer Masse
  • - bei Ausfall eines Brückenteils nur Reduzierung der Gesamtlänge und kein Ausfall des Gesamtsystems
  • - offene Struktur, wodurch Sicht zu Kupplungsstellen und anderen kritischen Stellen frei ist
  • - kein Aufrüsten hinter der Front, da alle Elemente austauschbar sind
  • - keine taktische Einschränkung (Entscheidung am Ziel über Brückenlänge).
The bridge according to the invention has the following advantages:
  • - little and small spare parts
  • - little wind exposure area
  • - little bombardment area
  • - Great variability, ie either a very long or several short bridges can be built by one vehicle at the same time
  • - no upright beam required up to 45 meters
  • - light weight
  • - low transport volume
  • - Better bridge view of the tank driver when approaching the bridge
  • - Parts can be replaced by hand and also carried as a replacement (in one example the telescope weighs 56 kg, a lower belt section 150 kg, a coupling 50 kg and a ramp 200 kg)
  • - higher natural frequency thanks to stiffer and smaller mass
  • - in the event of failure of a bridge part, only a reduction in the overall length and no failure of the overall system
  • - Open structure, which gives a clear view of coupling points and other critical points
  • - No upgrading behind the front, as all elements are interchangeable
  • - no tactical restriction (decision at the destination about bridge length).

Wesentlich für die Erfindung ist, daß die Brükkenelemente, ggf. in zusammengekuppeltem Zustand, nicht nur höhenverstellbar sind, sondern auch in ihrer jeweiligen Höhe fest verriegelt werden können, so daß, unter Verwendung von gleichen Brückenelementen, die Brücke verhältnismäßig leicht dem Momentenverlauf angepaßt werden kann und daß die Höhenverstellbarkeit der Brückenelemente im wesentlichen auf der Verstellbarkeit der Strebe(n) (D) beruht.It is essential for the invention that the bridge elements, possibly in the coupled state, are not only adjustable in height, but can also be locked in their respective heights, so that, using the same bridge elements, the bridge can be adapted relatively easily to the torque curve and that the height adjustment of the bridge elements is based essentially on the adjustability of the strut (s) (D).

Dies kann z.B. durch teleskopierbare und feststellbare Bauelemente (Fahrbahnplatten, Streben, und/oder Untergurte) oder durch Bauelemente erfolgen, die an ihren Enden in verschiedenen Abständen Koppelstellen aufweisen. In einer bevorzugten Ausführungsform sind die Diagonalstreben und/oder die Untergurte teleskopierbar. Sie können z.B. mit innenliegenden, bogenförmigen Nuten und Vorsprüngen ausgerüstet sein, sodaß durch Verdrehen der beiden Hälften eine Entriegelung erfolgt. Nach dem Auseinanderziehen oder Zusammenschieben kann der Träger in einer anderen Länge durch Verdrehen in eine andere Nut wieder verriegelt werden.This can be done, for example, by telescopic and lockable components (roadway plates, struts, and / or lower chords) or by components that have different ends at their ends have coupling points. In a preferred embodiment, the diagonal struts and / or the lower chords are telescopic. For example, they can be equipped with internal, arc-shaped grooves and projections so that unlocking takes place by turning the two halves. After pulling apart or pushing together, the carrier can be locked in a different length by turning it into a different groove.

Eine vom Gewicht her optimierte Ausführungsform weist pro Brückenelement zwei Fahrbahnplatten, zwei Untergurte und acht Diagonalstreben auf, die jeweils zwischen den Enden der Fahrbahnplatten und der Mitte der Untergurte angeordnet sind.An embodiment optimized in terms of weight has two roadway plates, two lower chords and eight diagonal struts per bridge element, each of which is arranged between the ends of the roadway plates and the center of the lower chords.

Wenn die Fahrbahnplatten einen U-förmigen Querschnitt haben, können in ihrem Inneren die Diagonalstreben und die Untergurte Platz finden.If the road slabs have a U-shaped cross-section, the diagonal struts and the lower chords can be accommodated inside.

In einer bevorzugten Ausführungsform werden zwei Fahrbahnplatten pro Brückenelement verwendet, die mit Querträgern miteinander verbunden sind. Genauso ist es jedoch möglich, statt der zwei Fahrbahnplatten eine breitere Fahrbahnplatte vorzusehen, die beide Spuren aufnimmt. Dies ist vorteilhaft für eine maschinelle Verlegung, wenn es auf die Tragbarkeit der Einzelteile nicht ankommt.In a preferred embodiment, two roadway plates are used per bridge element, which are connected to one another with cross members. However, it is equally possible to provide a wider carriageway slab instead of the two carriageway slabs, which takes up both tracks. This is advantageous for mechanical installation if the portability of the individual parts is not important.

Die Brücke weist dann ein besonders günstiges Verhältnis von Tragfähigkeit zu Gewicht auf, wenn ihr Höhen-zu Längenverhältnis im Bereich von 1: 10 bis 1: 30 liegt, bevorzugt bei 1: 20 liegt. Eine solche Brücke hat eine ausreichende Tragfähigkeit (MLC 60).The bridge has a particularly favorable load-bearing capacity to weight ratio if its height-to-length ratio is in the range from 1:10 to 1:30, preferably 1:20. Such a bridge has sufficient load-bearing capacity (MLC 60).

Ein Verlegefahrzeug, z.B. ein Radfahrzeug oder ein Verlegepanzer, der zum Verlegen der erfindungsgemäßen Brücke geeignet ist, hat einen ausfahrbaren Verlegebalken mit einem Fuß, der das Kippmoment des gesamten Fahrzeugs verbessert, eine im Fahrzeug höhenverstellbare Stütze mit einer oder mehreren Rollen, auf der der Verlegebalken verschiebbar ist, und einen Schlitten, der angehoben und gekippt werden kann zur Aufnahme der Brückenelemente.A laying vehicle, e.g. a wheeled vehicle or an installation tank, which is suitable for the installation of the bridge according to the invention, has an extendable installation beam with a foot that improves the tipping moment of the entire vehicle, a height-adjustable support in the vehicle with one or more rollers on which the installation beam can be moved, and a slide that can be lifted and tilted to accommodate the bridge elements.

Figur 1 zeigt drei mögliche Brücken, die jeweils aus mehreren Brückenelementen B bestehen. Jedes Brückenelement B besteht hier aus zwei Fahrbahnplatten F, zwei Untergurten U und mehreren Diagonalstreben D. Die hier gezeigten Brücken variieren in ihrer Länge von ca. 14 bis 27 Meter. Deutlich zu erkennen ist der erfindungsgemäße fachwerkartige Aufbau, bei dem z.B. die Fahrbahnplatten F einen Bogen und die Untergurte U eine dazugehörige Sehne bilden.Figure 1 shows three possible bridges, each consisting of several bridge elements B. Each bridge element B consists of two carriageway slabs F, two lower chords U and several diagonal struts D. The bridges shown here vary in length from approx. 14 to 27 meters. The truss-like structure according to the invention, in which e.g. the roadway plates F form an arch and the lower chords U form an associated chord.

Figur 2 zeigt erfindungsgemäße Brücken der Länge 33,5 und 40 Meter.Figure 2 shows bridges according to the invention with a length of 33.5 and 40 meters.

Figur 3 zeigt ein Brückenelement B. Es besteht aus zwei Fahrbahnplatten F, zwei Untergurten U und acht Diagonalstreben D. Beispielhafte Bemaßungen sind angegeben. Im unteren Teil der Figur 3, dem Querschnitt durch ein erfindungsgemäßes Brückenelement B ist der Querträger Q zu erkennen, der die beiden Fahrbahnplatten F miteinander verbindet. Die Diagonalstreben D und der Untergurt U könnten für den platzsparenden Transport in die Fahrbahnplatte F versenkt werden. Die Fahrbahnplatte F hat einen U-förmigen Querschnitt. Möglich aber nicht gezeigt sind auch andere Anordnungen der Diagonalstreben oder auch Streben die ungefähr senkrecht zur Fahrbahnplatte stehen. Über deren Längenverstellung kann ebenfalls die erfindungsgemäße Krümmung der Brücke erreicht werden.Figure 3 shows a bridge element B. It consists of two roadway plates F, two lower chords U and eight diagonal struts D. Exemplary dimensions are given. In the lower part of FIG. 3, the cross section through a bridge element B according to the invention, the cross member Q can be seen, which connects the two roadway plates F to one another. The diagonal struts D and the lower flange U could be sunk into the track plate F for space-saving transport. The carriageway slab F has a U-shaped cross section. Other arrangements of the diagonal struts or struts which are approximately perpendicular to the roadway plate are also possible but not shown. The curvature of the bridge according to the invention can also be achieved via its length adjustment.

Figur 4 zeigt eine Ausführung einer Diagonalstrebe D aus zwei gegeneinander verschiebbaren Teilen. In diesem Beispiel ist die Strebe von 3,1 bis 3,8 Meter längenveränderbar. Die Längenveränderung und Verriegelung erfolgt mit Hilfe von Vorsprüngen V und Nuten N, die miteinander in Eingriff gebracht werden können. Die Vorsprünge V und Nuten N sind hier bogenförmig ausgeführt, wie Figur 4 links unten zeigt. Durch Verdrehen der zwei Teile des Diagonalträgers D können die Vorsprünge aus den Nuten herausgeschoben oder in die Nuten wieder eingerastet werden. Dadurch wird eine einfache Längenveränderung und Verriegelung ermöglicht.Figure 4 shows an embodiment of a diagonal strut D from two mutually displaceable parts. In this example, the strut can be changed in length from 3.1 to 3.8 meters. The length change and locking takes place with the aid of projections V and grooves N, which can be brought into engagement with one another. The projections V and grooves N are of arcuate design here, as shown in FIG. 4 at the bottom left. By turning the two parts of the diagonal support D, the projections can be pushed out of the grooves or snapped into the grooves again. This enables simple length changes and locking.

Figur 5 zeigt zwei mögliche Rampen R und R'. Die oben gezeigte Rampe R ist starr ausgeführt und hat ein etwas geringeres Gewicht als die unten gezeigte schwenkbare Rampe R'. Die Rampen R und R' wirken jeweils mit den Fahrbahnplatten F und den Untergurten U zusammen. Beispielhafte Maßangaben für die Verschwenkwinkel sind der Figur zu entnehmen.Figure 5 shows two possible ramps R and R '. The ramp R shown above is rigid and has a slightly lower weight than the pivotable ramp R 'shown below. The ramps R and R 'each interact with the roadway plates F and the lower chords U. Exemplary dimensions for the swivel angle can be seen in the figure.

Figur 6 zeigt einen Verlegepanzer VP mit 46 Meter Brücke. Die Brücke ist in Form ihrer Brükkenelemente B auf einem Schlitten SL gelagert. Der Schlitten weist eine Hebe- und Verschwenkeinrichtung auf. Seine Bewegungsmöglichkeiten sind in der Figur 6 unten rechts angegeben. Der Verlegepanzer VP hat einen Verlegebalken VB, mit einem Fuß, mit dem das Kippmoment des Verlegepanzers VP erheblich erhöht werden kann. Damit ist es möglich,bis zu 46 Meter Brücke im freien Vorbau zu verlegen. Der Verlegepanzer VP weist weiterhin in seinem Mittelteil eine nach oben und unten verschiebbare Stütze ST auf, die an ihrer Oberseite eine Rolle trägt, auf der der Verlegebalken verschoben werden kann.Figure 6 shows an armored personnel carrier VP with 46 meter bridge. The bridge is mounted in the form of its bridge elements B on a slide SL. The carriage has a lifting and pivoting device. Its movement possibilities are indicated in the bottom right of FIG. 6. The installation armor VP has an installation beam VB, with a foot, with which the tilting moment of the installation armor VP can be increased considerably. So that is it is possible to lay up to 46 meters of bridge in the free porch. The installation armor VP also has in its middle part an up and down movable support ST which carries a roller on its top on which the installation beam can be moved.

Figur 7 zeigt den Verlegevorgang mit dem Verlegepanzer VP. Als erstes werden die Brückenelemente B mit dem Schlitten SL nach hinten verfahren und der Verlegebalken VB mit dem Fuß nach vorne ausgefahren. Im nächsten Schritt wird der Schlitten gekippt, sodaß die Brückenelemente B durch Ausfahren der Diagonalstreben und der Untergurte auf ihre vorgesehene Höhe gebracht werden können. Im untersten Bild ist der Verlegevorgang in einem fortgeschrittenen Stadium gezeigt. Die fertigen Brückenelemente B werden dann noch auf dem Verlegefahrzeug VP aneinandergekoppelt und über den Verlegebalken VB über das Hindernis geschoben. Beispielhafte Angaben für den Platzbedarf am Ufer sind der Figur 7 unten zu entnehmen.FIG. 7 shows the laying process with the laying armor VP. First, the bridge elements B are moved backwards with the slide SL and the laying beam VB is extended forward with the foot. In the next step, the slide is tilted so that the bridge elements B can be brought to their intended height by extending the diagonal struts and the lower chords. In the bottom picture the laying process is shown in an advanced stage. The finished bridge elements B are then coupled together on the laying vehicle VP and pushed over the obstacle via the laying beam VB. Exemplary information on the space requirement on the bank can be found in FIG. 7 below.

Figur 8 zeigt verschiedene Brückenkombinationen, die ein einziges Verlegefahrzeug wahlweise verlegen kann. Es können entweder 4 x 13 Meter lange Brücken oder 2 x 24 Meter lange Brücken oder zwei 13 Meter lange und eine 24 Meter lange Brücke oder eine 35 Meter lange und eine 13 Meter lange Brücke oder eine 46 Meter lange Brücke verlegt werden.Figure 8 shows various bridge combinations that a single laying vehicle can choose to lay. Either 4 x 13 meter long bridges or 2 x 24 meter long bridges or two 13 meter long and one 24 meter long bridge or one 35 meter long and one 13 meter long bridge or a 46 meter long bridge can be laid.
