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.

Aus der DE-AS 12 07 948 ist eine zerlegbare Brücke bekannt, die aus mehreren zusammenkuppelbaren Brückenelementen besteht. Die Brückenelemente enthalten je eine Fahrbahnplatte, Untergurte und Streben. 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 DE-AS 12 07 948 a collapsible bridge is known, which consists of several interconnectable bridge elements. The bridge elements each contain a carriageway slab, lower chords and struts. 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.

Aus der DE-OS 38 14 502 ist eine gattungsgleiche zerlegbare Brücke aus einzelnen zu- sammenkuppelbaren Brückenelementen bekannt. Die Brückenelemente bestehen aus einem Fachwerk aus Fahrbahnplatten, Untergurten und Diagonalstreben. Da die Untergurte und die Diagonalstreben in ihrer Länge teleskopierbar sind oder an bestimmten Kupplungsstellen befestigbar sind, kann die Höhe der Bauelemente verstellt werden. DE-OS 38 14 502 discloses a bridge of the same type that can be dismantled from individual bridge elements that can be coupled together. The bridge elements consist of a truss consisting of road slabs, lower chords and diagonal struts. Since the lower chords and the diagonal struts are telescopic in length or can be attached to certain coupling points, the height of the components can be adjusted.

Aufgabe der Erfindung ist es, eine solche Brücke dahingehend zu verbessern, daß sie leichter und einfacher im Aufbau wird.The object of the invention is to improve such a bridge that it becomes lighter and simpler in construction.

Diese Aufgabe wird erfindungsgemäß gelöst mit den kennzeichnenden Merkmalen im Anspruch 1. Besondere Ausführungsarten der Erfindung sind Gegenstände von Unteransprüchen.This object is achieved according to the invention with the characterizing features in claim 1. Special embodiments of the invention are the subject of subclaims.

Die erfindungsgemäße Brücke hat im wesentlichen die Vorteile der in der DE-OS 38 14 502 genannten Brücke, wie

  • wenig Windangriffsfläche
  • wenig Beschußfläche
  • große Variabilität, das heißt, es können entweder eine sehr lange oder mehrere kurze Brücken gleichzeitig von einem Fahrzeug gebaut werden
  • bis ca. 45 Meter kein Vorbauträger nötig
  • geringes Gewicht
  • geringes Transportvolumen
  • gute Brückensicht des Panzerfahrers bei Anfahrt auf der Brücke
  • 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 essentially has the advantages of the bridge mentioned in DE-OS 38 14 502, such as
  • little wind exposure area
  • little bombardment area
  • great variability, which means that either a very long bridge or several short bridges can be built simultaneously by one vehicle
  • up to approx. 45 meters no porch girders required
  • light weight
  • low transport volume
  • good bridge view of the tank driver when approaching the bridge
  • 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 limitation (decision at the destination about bridge length).

Die erfindungsgemäße Brücke ist leichter und einfacher im Aufbau als die eben beschriebene, da keine teleskopierbaren Teile (die doppelwandig ausgelegt sein müssen) mehr notwendig sind. Höhe und Neigung der Brückenmodule sind in weitem Rahmen frei wählbar. Die Anlenkung der Diagonalelemente an den Enden der Untergurte erlaubt einen leichteren Aufbau der Untergurte als bei einer Anlenkung in der Mitte. Die Ausführung mit den sehr kurzen Diagonalelementen (kürzer als die halben Untergurte) reduziert nochmals das Gesamtgewicht. Durch die Kürze der Untergurte gegenüber der Fahrbahn ergibt sich eine grössere Höhe der Brücke (ein Bogen) ganz automatisch mit der grösseren Länge.The bridge according to the invention is lighter and simpler in construction than the one just described, since there are no telescopic parts (the double-walled design have to be) are more necessary. The height and inclination of the bridge modules are freely selectable. The articulation of the diagonal elements at the ends of the lower chords allows the lower chords to be constructed more easily than with a articulation in the middle. The version with the very short diagonal elements (shorter than half the lower chords) further reduces the overall weight. The shortness of the lower chords compared to the roadway automatically results in a higher bridge height (an arch) with the greater length.

Die Erfindung wird anhand der Zeichnung näher erläutert.The invention is explained in more detail with reference to the drawing.

Es zeigt

  • Fig. 1 ein erfindungsgemäßes Brückenmodul, und
  • Fig. 2 drei mögliche Brücken.
It shows
  • 1 shows a bridge module according to the invention, and
  • Fig. 2 three possible bridges.

Fig. 1 zeigt oben ein Brückenmodul B im Transportzustand (oder als Kurzbrücke) und in der Mitte und unten ein Brückenmodul B im entfalteten Zustand. Das Brückenmodul B besteht hier aus einem Fahrbahnelement F, zwei Untergurten U und vier Diagonalstreben D. Die Diagonalstreben D und der Untergurt U können für den platzsparenden Transport in das Fahrbahnelement F versenkt werden. Das Fahrbahnelemente F hat hier, wie unten zu sehen ist, einen U-förmigen Querschnitt, der in der Mitte Raum für einen Vorbauträger oder einen Vorbauschnabel oder einen Verlegebalken läßt. Es ist gut zu erkennen, daß der Untergurt U kürzer ist als Fahrbahnelement F, wodurch der Untergurt U vollständig in dem Fahrbahnelement F "versenkt" werden kann. Auch die relativ kurzen Diagonalstreben D können im Transportzustand oder in der Kurzbrücke vollständig im Fahrbahnelement F versenkt sein. Zu erkennen sind weiterhin die unterschiedlichen Befestigungsmöglichkeiten für die Diagonalelemente D und den Untergurt U in dem Fahrbahnelement F. In dieser Ausführung sind an jedem Ende des Fahrbahnelements F je unterschiedliche Befestigungsmöglichkeiten 1, 2, 3, 0 für die Diagonalen D und für den Untergurt U gezeigt. In diesem Beispiel sind die Befestigungsmöglichkeiten 1, 2, 3, 1', 2', und 3' für die Untergurte U und die Befestigungsmöglichkeiten 1, 3, 1' und 3' auch für die Diagonalstreben D vorgesehen.
Sollten andere Höhen oder Neigungsmöglichkeiten der Brückenelemente B erwünscht sein, liegen die Befestigungspunkte an anderen Stellen. Das obere Ende der Diagonalen D ist hier (z.B. in Schienen) in dem Fahrbahnelement F geführt. Im zusammengefalteten Zustand liegt das obere Ende beim Punkt 0 (0'). Beim Anheben von F entfaltet sich U und D automatisch. Der Befestigungspunktes 1 ist vom Befestigungspunkt 0 um die Länge einer Diagonale D entfernt.1 shows a bridge module B in the transport state (or as a short bridge) at the top and a bridge module B in the unfolded state in the middle and below. The bridge module B here consists of a roadway element F , two lower chords U and four diagonal struts D. The diagonal struts D and the lower flange U can be sunk into the track element F for space-saving transport. Here, as can be seen below, the roadway element F has a U-shaped cross section, which leaves space in the middle for a stem support or a stem beak or a laying beam. It can be clearly seen that the lower flange U is shorter than the roadway element F , as a result of which the lower flange U can be completely "sunk" into the roadway element F. The relatively short diagonal struts D can also be completely sunk in the roadway element F in the transport state or in the short bridge be. The different fastening options for the diagonal elements D and the lower flange U in the carriageway element F can also be seen . In this embodiment, different fastening options 1, 2, 3, 0 for the diagonals D and for the lower flange U are shown at each end of the roadway element F. In this example, the fastening options 1, 2, 3, 1 ', 2', and 3 ' for the lower chords U and the fastening options 1, 3, 1' and 3 'are also provided for the diagonal struts D.
If other heights or inclinations of the bridge elements B are desired, the attachment points are at different locations. The upper end of the diagonal D is here (for example in rails) in the carriageway element F. In the folded state, the upper end is at point 0 ( 0 ' ). When F is raised , U and D unfold automatically. The attachment point 1 is removed from the attachment point 0 by the length of a diagonal D.

Fig. 2 zeigt drei Ausführungen von erfindungsgemäßen Brücken, die aus jeweils 1, 2 oder 3 der in Fig. 1 gezeigten Brückenmodule B montiert sind. Fig. 1 zeigt oben eine kurze Brücke, deren Länge einem Brückenmodul B und deren Höhe der Höhe des Fahrbahnelements F entspricht. Die Diagonalen D und die Untergurte U sind, wie in Fig. 1 oben gezeigt, in dem Fahrbahnelement F versenkt.
Fig. 2 zeigt in der Mitte eine aus zwei Brückenmodulen B zusammengekuppelte Brücke mittlerer Spannweite. Die Untergurte U sind nicht mehr an den äusseren Befestigungspunkten 1, sondern an den weiter innenliegenden Befestigungspunkten 2 und 2' angeordnet. Das andere Ende der Untergurte ist jeweils mit dem Untergurt des anderen Brückenmoduls verbunden. Die oberen Enden der mittleren Diagonalstreben D verschieben sich während des Entfaltens von den Punkten 0 oder 0' auf 3 oder 3'. Die Brücke weist gegenüber der kurzen Brücke eine grössere Höhe und damit eine der grösseren Länge angepasste Tragkraft auf.
Fig. 2 zeigt unten eine aus drei Brückenmodulen B zusammengesetzte lange Brücke mit der entsprechend grösseren Höhe H3. Im linken Brückenelement B ist der Untergurt U am Befestigungspunkt 3, der weiter vom Ende entfernt ist als der Befestigungspunkt 2, angelenkt. Die linke Diagonale D liegt ohne Funktion in der Fahrbahn F. Die rechte Diagonale des linken Brückenmoduls B ist im Befestigungspunkt 1' des Fahrbahnelements F angelenkt. Für das rechte Brückenmodul B gilt spiegelbildlich das gleiche. Das mittlere Brückenmodul B ist zwischen die beiden genannten Brückenmodule B gekuppelt. Die Untergurte U der drei Brückenmodule sind direkt miteinander verbunden, die Fahrbahnelemente ebenfalls, so daß sich der gewünschte höhere Bogen ergibt. Die Diagonalstreben D des mittleren Brückenmoduls sind in den Befestigungspunkten 3, 3' des Fahrbahnelements F des mittleren Brückenmoduls B befestigt.FIG. 2 shows three versions of bridges according to the invention, each of which is assembled from 1, 2 or 3 of the bridge modules B shown in FIG. 1. 1 shows a short bridge at the top, the length of which corresponds to a bridge module B and the height of which corresponds to the height of the roadway element F. The diagonals D and the lower chords U are, as shown in FIG. 1 above, sunk in the roadway element F.
Fig. 2 shows in the middle a bridge of medium span coupled together from two bridge modules B. The lower chords U are no longer arranged at the outer fastening points 1 , but at the further inner fastening points 2 and 2 ' . The other end of the lower chord is connected to the lower chord of the other bridge module. The top The ends of the middle diagonal struts D shift from the points 0 or 0 ' to 3 or 3' during the unfolding. The bridge has a greater height than the short bridge and thus a load capacity adapted to the greater length.
2 shows a long bridge composed of three bridge modules B with the correspondingly larger height H3 . In the left bridge element B , the lower flange U is articulated at the attachment point 3 , which is farther from the end than the attachment point 2 . The left diagonal D has no function in the lane F. The right diagonal of the left bridge module B is articulated at the fastening point 1 'of the road element F. The same applies to the right bridge module B in mirror image. The middle bridge module B is coupled between the two bridge modules B mentioned . The lower chords U of the three bridge modules are directly connected to each other, as are the road elements, so that the desired higher curve results. The diagonal struts D of the middle bridge module are fastened in the fastening points 3, 3 'of the roadway element F of the middle bridge module B.

Es sind auch Brücken mit mehr als drei solcher Elemente B möglich.Bridges with more than three such elements B are also possible.
