Description

Die Erfindung betrifft mobile militärische Brückensysteme in Trogbrückenbauweise gemäß dem Oberbegriff des Anspruchs 1.The invention relates to mobile military bridge systems in trough bridge construction according to the preamble of claim 1.

Mobile militärische Brückensysteme sind in vielen Ausführungen bekannt. Je nach Gewichtsklasse erfolgen Transport und Verlegung durch Kettenfahrzeuge, durch Lkw oder auch von Hand. In allen Fällen sind die Brückenelemente während des Transports platzsparend zerlegt.Mobile military bridge systems are known in many designs. Depending on the weight class, transport and installation are carried out by tracked vehicles, trucks or even by hand. In all cases, the bridge elements are split to save space during transport.

Aus der DE 42 40 575 A und der DE 102 42 860 B sind zerlegbare Brücken bekannt, bestehend aus zwei parallelen Längsträgern in Fachwerkbauweise mit dreieckigem Querschnitt. Für den Transport sind die Längsträger zusammenlegbar. Um die Fahrbahn zwischen den Längsträgern verlegen zu können, sind Querträger vorgesehen, die vollständig durch die Längsträger hindurch gesteckt und kraftschlüssig mit diesen verbunden sind. Auf diese Querträger werden Spurträger bzw. Fahrbahnplatten aufgelegt und ebenfalls kraftschlüssig verbunden. Diese Brückensysteme besitzen somit relativ viele Einzelteile, wodurch Montage und Demontage verzögert werden.From the DE 42 40 575 A and the DE 102 42 860 B demountable bridges are known, consisting of two parallel longitudinal beams in truss construction with triangular cross-section. For transport, the longitudinal beams are collapsible. In order to be able to lay the roadway between the longitudinal members, cross members are provided, which are completely inserted through the longitudinal members and frictionally connected thereto. On this cross member track carrier or carriage plates are placed and also connected non-positively. These bridge systems thus have a relatively large number of individual parts, whereby assembly and disassembly are delayed.

Aus der DE-Auslegeschrift 1 207 948 ist eine zerlegbare Grabenbrücke bekannt, bestehend aus unmittelbar befahrbaren Obergurttafeln, am Stoß der Obergurttafeln angeordneten Querrahmen mit an der Obergurttafel in der Ebene der beiden Längswände schwenkbar angeschlossenen Pfosten und die Pfosten verbindenden Untergurtstäben, bei der die Querrahmen und mit ihnen die Untergurtstäbe für den Transport gegen die Obergurttafeln klappbar sind. Die Pfosten sind auch an den Untergurten schwenkbar angeschlossen und der Höhe nach in zwei Teile geteilt, die durch sperrbare Gelenke verbunden und im Transportzustand in Längsrichtung nach innen umgelegt sind. Die Untergurte sind zusätzlich durch Querverbände miteinander verbunden. In der Ebene beider Längswände sind zwei sich kreuzende Zugdiagonalen aus einer einstellbaren Spannhülse und einem Rundstab angeordnet. Im Transportzustand muss der Rundstab um das Maß der Diagonalverkürzung zurückgeschoben und im Einbauzustand aus der Spannhülse herausgezogen werden.From the DE-Auslegeschrift 1 207 948 a demountable trench bridge is known, consisting of immediately passable upper chord panels, arranged at the top of the upper chord panels transverse frame with pivotally connected to the top chord in the plane of the two longitudinal walls connected post and the jamb Untergurtstäben, in which the transverse frame and with them the Untergurtstäbe for transport against the upper belt panels are foldable. The posts are also pivotally connected to the lower chords and the height divided into two parts, which are connected by lockable joints and folded in the transport state in the longitudinal direction inwards. The lower straps are also connected by cross-bandages. In the plane of both longitudinal walls two crossing Zugdiagonalen of an adjustable clamping sleeve and a round rod are arranged. In the transport state, the round rod must be pushed back by the amount of diagonal shortening and pulled out of the clamping sleeve in the installed state.

Aufgabe der mobilen militärischen Brücken ist es, Hindernisse wie Bäche, Flüsse, Felsschluchten und dergleichen zu überbrücken. Dazu haben diese Brücken eine Spannweite von 20 bis 30 m. Um Brücken dieser Länge frei vorbauen zu können, bedarf es spezieller Verlegvorrichtungen. Die vorgenannten Druckschriften machen zu diesem Thema keine Angaben, ebenso wenig über geeignete Transportfahrzeuge.The task of mobile military bridges is to bridge obstacles such as streams, rivers, canyons and the like. These bridges have a span of 20 to 30 m. To build bridges of this length freely, it requires special installation devices. The aforementioned documents make no information on this subject, nor about suitable transport vehicles.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein mobiles militärisches Brückensystem der eingangs genannten Art anzugeben, welches einfach und schnell montiert und demontiert sowie platzsparend transportiert werden kann.The present invention has for its object to provide a mobile military bridge system of the type mentioned, which can be easily and quickly assembled and disassembled and transported to save space.

Diese Aufgabe wird gelöst durch ein mobiles militärisches Brückensystem mit den Merkmalen des Anspruchs 1.This object is achieved by a mobile military bridge system with the features of claim 1.

Ein wesentlicher Vorteil des erfindungsgemäßen Brückensystems ist die hohe Stabilität und Tragkraft der Längsträger. Aufgrund der Kastenform sind die Längsträger selbst bereits als Notbrücke z. B. für Fußgänger verwendbar. Das Einhängen der Fahrbahnplatten zwischen die Längsträger ist in kürzester Zeit erledigt. Die entfalteten Längsträger, bestehend aus jeweils zwei Fachwerkträgern, sind an jedem Knotenpunkt des Untergurts über schwenkbare Querträger verbunden. Dabei erfolgt die Verbindung der schwenkbaren Querträger zum jeweils inneren Fachwerkträger biegesteif bei den Fachwerkknoten.A significant advantage of the bridge system according to the invention is the high stability and load capacity of the side members. Due to the box shape, the longitudinal members themselves are already as emergency bridge z. B. suitable for pedestrians. The suspension of the deck plates between the side members is done in no time. The unfolded side members, each consisting of two truss girders, are connected at each node point of the lower chord by means of pivotable cross members. The connection of the pivotable cross member to the respective inner truss girder takes place rigidly at the truss nodes.

Dank der ebenfalls biegesteifen Verbindung zwischen den Fachwerkknoten und den Fahrbahnplatten werden die Lasten nahezu gleichmäßig auf die beiden Fachwerksebenen der rechteckigen Längsträger übertragen. Die schwenkbaren Querträger können zum Falten vorteilhaft in Längsrichtung, d. h. in Richtung der Längsträger, geschwenkt werden. Schließlich lässt sich durch das Falten der rechteckigen Längsträger das Transportvolumen auf unter 40 % reduzieren.Thanks to the likewise rigid connection between the truss nodes and the carriageway slabs, the loads are transmitted almost equally to the two truss levels of the rectangular side members. The pivotable cross member may be advantageous for folding in the longitudinal direction, d. H. in the direction of the side members, to be pivoted. Finally, the transport volume can be reduced to less than 40% by folding the rectangular side members.

Gemäß einer Weiterbildung der Erfindung besitzen die schwenkbaren Querträger auf der Seite der Fahrbahnplatten formschlüssige Verbindungsteile, die sowohl Biegemomente als auch Querkräfte übertragen können. Auf der Gegenseite sind diese formschlüssigen Verbindungsteile so gestaltet, dass nur Querkräfte übertragen werden.According to one embodiment of the invention, the pivotable cross member on the side of the carriage plates form-fitting connection parts that can transmit both bending moments and shear forces. On the opposite side of these positive connecting parts are designed so that only lateral forces are transmitted.

Gemäß einer bevorzugten Ausgestaltung der Erfindung sind die Achsen der schwenkbaren Querträger an den unteren Doppelgelenkscharnieren gelagert. Dadurch bleiben die schwenkbaren Querträger auch im gefalteten Zustand der Längsträgermodule mit diesen verbunden und müssen nicht separat transportiert und verzurrt werden.According to a preferred embodiment of the invention, the axes of the pivotable cross member are mounted on the lower double joint hinges. As a result, the pivotable cross member remain in the folded state of the side member modules connected to these and need not be transported separately and lashed.

Durch die Verschwenkung um 90 Grad werden die schwenkbaren Träger in eine optimale Transportlage gebracht und liegen parallel zwischen den Fachwerksebenen. Durch die Schwenklagerverbindung zu den Doppelscharnieren wird nach dem Entfalten und Verriegeln der schwenkbaren Querträger gleichzeitig eine Stabilisierung der Doppelscharniere erreicht.By pivoting 90 degrees, the pivotable carriers are brought into an optimal transport position and lie parallel between the truss levels. By the pivot bearing connection to the double hinges stabilization of the double hinges is achieved after unfolding and locking the pivotal cross member simultaneously.

Zur optimalen Übertragung der Lasten ist die Verbindung zwischen den Untergurten und den Fahrbahnplatten bzw. den Fahrbahnplatten-Querträgern biegesteif und schubfest ausgeführt.For optimum transfer of the loads, the connection between the lower chords and the roadway slabs or the slab crossbeams is rigid and shear resistant.

Zur Kopplung der Fahrbahnplatten bzw. Fahrbahnplatten-Querträger mit den Längsträgern sind an den Knotenpunkten der Untergurte entsprechende Formstücke vorgesehen. Diese Formstücke sind vorteilhaft in Querrichtung, bezogen auf die Fahrbahnplatten, versetzt angeordnet. Dadurch können die Fahrbahnplatten zum Kuppeln direkt vertikal abgesenkt werden und müssen nicht zusätzlich horizontal verschoben werden. Die vertikale Sicherung erfolgt durch handelsübliche federunterstützte Sperrelemente.For coupling the roadway slabs or roadway slab cross members with the longitudinal beams, corresponding shaped pieces are provided at the junctions of the lower chords. These fittings are advantageous in the transverse direction, with respect to the roadway plates, arranged offset. As a result, the road slabs for coupling can be lowered directly vertically and do not have to be moved horizontally. The vertical backup is done by commercially available spring-assisted locking elements.

Gemäß einer Weiterbildung der Erfindung sind im Obergurtbereich in den mittleren Gelenken der Querverbindungen Sperrelemente vorgesehen, die das Scharnier biegesteif blockieren.According to one embodiment of the invention blocking elements are provided in the upper belt area in the middle joints of the cross connections, which block the hinge rigid.

Zur Kopplung zweier Längsträger ist an den Enden der Untergurte einerseits ein Haken, andererseits eine Gabel mit feststehendem Bolzen vorgesehen.For coupling two longitudinal beams, on the one hand a hook, on the other hand a fork with a fixed bolt is provided at the ends of the lower straps.

Alternativ hierzu kann auch eine Auge-Gabel-Verbindung mit lösbarem Bolzen eingesetzt werden.Alternatively, an eye-fork connection with releasable bolt can be used.

Zu demselben Zweck sind an den Enden der Obergurte einerseits ein Bolzen, andererseits ein federbelasteter Haken und beidseits Druckleisten mit Längs- und Querkraftübertragung vorgesehen.For the same purpose at the ends of the upper straps on the one hand a bolt, on the other hand a spring-loaded hook and on both sides pressure bars with longitudinal and transverse force transmission provided.

Vorteilhafterweise liegen Bolzen und Haken im Inneren des Obergurts und ein außenliegender Hebel ermöglicht das Öffnen des Hakens.Advantageously, bolts and hooks are inside the upper belt and an external lever allows the opening of the hook.

Gemäß einer Ausgestaltung der Erfindung ist wenigstens an den Enden der Fahrbahn ein Fahrbahnplatten-Querträger zwischen den Längsträgern eingehängt, der eine Auffahrrampe trägt.According to one embodiment of the invention, at least at the ends of the roadway a roadway crossmember is suspended between the longitudinal members, which carries a ramp.

Vorteilhafterweise ist die Auffahrrampe als Schlepprampe ausgeführt.Advantageously, the ramp is designed as a tow ramp.

Wie eingangs angedeutet, ist Gegenstand der vorliegenden Erfindung auch eine geeignete Verlegevorrichtung.As indicated at the outset, the subject of the present invention is also a suitable laying device.

Erfindungsgemäß umfasst diese Verlegevorrichtung zwei Verlegerrahmen, die jeweils einen Längsträger aufnehmen können, einen diese Verlegerrahmen verbindenden torsionssteifen Querrahmen, höhenverstellbare auskragende Rollenträger an den Verlegerrahmen, Hydraulikzylinder zum Heben und Senken der Rollenträger und eine dazu geeignete Hydraulikpumpe.According to the invention, this laying device comprises two laying frames, each of which can accommodate a longitudinal beam, a torsion-resistant transverse frame connecting this laying frame, height-adjustable cantilevered roll supports to the laying frame, hydraulic cylinders for raising and lowering the roll supports and a hydraulic pump suitable for this purpose.

Dank der höhenverstellbaren Rollenträger kann die Vorschubrichtung der Längsträger an die örtlichen Verhältnisse angepasst werden. Dank der torsionssteifen Verbindung der beiden Verlegerrahmen kann während des freien Vorbaus des einen Längsträgers der andere Längsträger als Gegengewicht benutzt werden. Auf diese Weise lassen sich auch Hindernisse mit einer Breite von 20 und mehr Metern ohne Hilfseinrichtungen oder zusätzliche Gegengewichte wie Ketten- oder Radfahrzeuge überwinden.Thanks to the height-adjustable roller carriers, the feed direction of the side members can be adapted to local conditions. Thanks to the torsionally rigid connection of the two frames, the other side member can be used as a counterweight during the free stem of one longitudinal member. In this way, even obstacles with a width of 20 and more meters without auxiliary equipment or additional counterweights such as tracked or wheeled vehicles overcome.

Vorteilhafterweise besitzt jeder Verlegerrahmen drei Anschlusspunkte für den Rollenträger, was eine flexible Anpassung an die örtlichen Gegebenheiten ermöglicht. Diese Anschlusspunkte sitzen auf der Vorderseite, auf der Rückseite oder auch in zwei verschiedenen Höhen.Advantageously, each frame has three connection points for the roller carrier, which allows flexible adaptation to local conditions. These connection points are located on the front, on the back or in two different heights.

Zum Vorschieben des Längsträgers ist im Verlegerrahmen ein Kurbeltrieb installiert. Dies unterstützt den freien Vorbau der Brücke von Hand, d. h. ohne Ketten- oder Radfahrzeuge.To advance the longitudinal member, a crank mechanism is installed in the frame. This supports the free stem of the bridge by hand, d. H. without chain or wheeled vehicles.

Um das Aufrichten der Verlegerrahmen zu unterstützen, ist an ihnen je ein Aufrichthebel mit Laufrolle gelagert. Ein Hydraulikzylinder betätigt den Aufrichthebel.In order to support the erection of the frame, a Aufrichthebel with roller is mounted on each of them. A hydraulic cylinder actuates the righting lever.

Vorzugsweise ist zwischen Hydraulikzylinder und Aufrichthebel ein Zugseil eingeschert.Preferably, a pull rope is reeved between the hydraulic cylinder and erect lever.

Das Bedienungspersonal kann somit allein durch Betätigen der Hydraulikpumpe die gesamte Verlegevorrichtung in Position bringen.The operator can thus bring the entire laying device in position solely by operating the hydraulic pump.

Vorteilhafterweise ist im Bodenbereich des Verlegerrahmens eine Kippsicherung vorgesehen.Advantageously, a tilt protection is provided in the bottom region of the frame.

Zur Verbesserung des Standes ist unter der Verlegevorrichtung ein Auflagekissen montierbar.To improve the state, a support cushion can be mounted under the laying device.

Zur Gewährleistung der Parallelität der Längsträger während des Verlegvorgangs ist eine abgespannte Druckstange vorgesehen. Diese Druckstange ist Teil eines Rollwagens, der auf den Obergurten der beiden Längsträger lauffähig ist.To ensure the parallelism of the longitudinal members during the laying process a guyed push rod is provided. This push rod is part of a trolley, which is executable on the upper chords of the two side members.

Vorteilhafterweise besitzt der Rollwagen seitliche Führungsrollen.Advantageously, the trolley has lateral guide rollers.

Betätigt wird dieser durch einen Hydraulikzylinder 57, wobei zwischen den Hydraulikzylinder 57 und den Aufrichthebel 56 ein Seilzug eingeschert ist.Fig. 8 shows a laying frame 51 in side view during erection. As Aufrichthilfe a Aufrichthebel 56 is provided with roller. This is actuated by a hydraulic cylinder 57, wherein between the hydraulic cylinder 57 and the erecting lever 56, a cable is reeved.

Am Boden des Verlegerrahmens 51 erkennt man eine Kippsicherung 58.At the bottom of the frame 51, a tilt lock 58 can be seen.

Um auch bei schlechtem Untergrund einen sicheren Stand der Verlegevorrichtung 50 zu erreichen, kann unter den Verlegerrahmen 51 ein Auflagekissen 70 montiert werden.In order to achieve a secure state of the laying device 50 even with a bad surface, a support cushion 70 can be mounted under the frame 51.

Fig. 9 zeigt die Verlegevorrichtung 50 während des Verlegens der Längsträger 11. Jeder Verlegerrahmen 51 nimmt je eine Reihe von Längsträgern 11 auf. Während die einen Längsträger 11, in der Zeichnung die vorderen, frei über das Hindernis vorgeschoben werden, dienen die anderen Längsträger 11, in der Zeichnung die hinteren, dabei als Gegengewicht. Dadurch behält die Verlegevorrichtung 50 ihren sicheren Stand, bis die Spitze der vorgeschobenen Längsträger 11 auf der gegenüberliegenden Seite des Hindernisses aufliegt.FIG. 9 shows the laying device 50 during the laying of the longitudinal beams 11. Each laying frame 51 accommodates a number of longitudinal beams 11 each. While the one longitudinal member 11, in the drawing, the front, are pushed freely over the obstacle, the other side members 11, in the drawing, the rear, while serving as a counterweight. As a result, the laying device 50 keeps its secure state until the tip of the advanced side member 11 rests on the opposite side of the obstacle.

Sobald dies erreicht ist, werden die Längsträger 11, die bisher als Gegengewicht gedient haben, ebenfalls vorgeschoben. Dazu wird deren Rollenträger 53 nach vorne umgesetzt. Die Parallelität der beiden Längsträger 11 während des Verlegvorgangs wird durch eine abgespannte Druckstange (nicht dargestellt) gewährleistet. Diese ist Teil eines Rollwagens (nicht dargestellt), der auf den Obergurten 12 lauffähig ist. Dazu besitzt der Rollwagen seitliche Führungsrollen.Once this is achieved, the side members 11, which have been used as a counterweight, also advanced. For this purpose, the roller carrier 53 is moved forward. The parallelism of the two side members 11 during the laying process is ensured by a guyed push rod (not shown). This is part of a trolley (not shown), which is capable of running on the upper chords 12. For this purpose, the trolley has lateral guide rollers.

Fig. 10 zeigt ein komplettes Element der erfindungsgemäßen Brücke, bestehend aus zwei parallelen Längsträgern 11 im ausgeklappten Zustand, zwischen denen Fahrbahnplatten 30 verlegt sind. Aufgrund der biegesteifen Verbindung zwischen den Untergurten 13 der Längsträger 11, hervorgerufen durch die horizontal verschwenkten Querträger 23, einerseits und die biegesteife und schubfeste Verbindung der Fahrbahnplatten 30 mit den Längsträgern 11, hervorgerufen durch die Formelemente 28 an den Fachwerksknoten der Untergurte 13 und die Haken 31 an den Fahrbahnplatten 30, andererseits bildet die Brücke ein stabiles formsteifes Gebilde hoher Tragfähigkeit, bei dem die auf die Fahrbahnplatten 30 drückende Last gleichmäßig auf die Längsträger 11 abgetragen wird.Fig. 10 shows a complete element of the bridge according to the invention, consisting of two parallel side rails 11 in the unfolded state, between which deck plates 30 are laid. Due to the rigid connection between the lower chords 13 of the side members 11, caused by the horizontally pivoted cross member 23, on the one hand and the rigid and shear-resistant connection of the deck plates 30 with the longitudinal members 11, caused by the mold elements 28 to the truss node of the lower chords 13 and the hooks 31st on the carriageway panels 30, on the other hand, the bridge forms a stable dimensionally stable structure of high load capacity, in which the load on the deck plates 30 load is removed evenly on the side members 11.

Fig. 10 lässt des weiteren erkennen, dass eine Reihe von Längsträgern 11 alleine schon als Notbrücke für Fußgänger dienen kann, da die unteren Doppelgelenkscharniere 21 sowie die diese mit den Untergurten 13 verbindenden Plattenelemente 25 begehbar sind.FIG. 10 further reveals that a series of longitudinal members 11 alone can already serve as an emergency bridge for pedestrians, since the lower double joint hinges 21 and the plate elements 25 connecting them to the lower chords 13 can be walked on.
