Abstract
Description
Die Erfindung betrifft eine aus in Längsrichtung ein oder zwei Spurträgerpaaren bestehende handbaubare Grabenbrücke, bei der die mit Abstand parallel angeordneten Spurträger durch Spurstangen vebindbar sind, und ein Verfahren zur Handverlegung der Grabenbrücke.The invention relates to a hand-built trench bridge consisting of one or two pairs of track carriers in the longitudinal direction, in which the track carriers arranged in parallel at a distance can be connected by tie rods, and a method for manual laying of the trench bridge.
Grabenbrücken im Sinne des Oberbegriffs des Hauptanspruchs sind zerlegbare Brücken, die zum Überspannen von Gräben oder Flüssen verwendet werden, wobei die Gesamtlänge der Brücke zwischen 5 Metern bis etwa 10 Metern beträgt.Trench bridges in the sense of the preamble of the main claim are collapsible bridges that are used to span ditches or rivers, the total length of the bridge being between 5 meters and about 10 meters.
Bei bekannten zerlegbaren Brücken, die für den Katastrophen- oder Kriegseinsatz verwendet werden, findet die Verlegung der Brücke unter Benutzung eines Vorbauträgers oder Vorbauschnabels statt. Diese Vorbauelemente sind zusätzliche Mittel, müssen transportiert und gehandhabt werden.In the case of known disassemblable bridges which are used for disaster or war operations, the bridge is laid using a stem girder or stem. These stem elements are additional resources and have to be transported and handled.
Die bekannten Vorbauelemente werden zunächst über das Hindernis (Graben, Fluß) vorgeschoben und anschließend wird die eigentliche Brücke über das Vorbauelement von einem Ufer auf das jenseitige Ufer gerollt. Nachdem die Brücke ausgelegt ist, wird das Vorbauelement je nach Verlegeart entweder entfernt oder es verbleibt innerhalb der Brücke.The known stem elements are first advanced over the obstacle (ditch, river) and then the actual bridge over the stem element is rolled from one bank to the other bank. After the bridge has been laid out, depending on the type of installation, the stem element is either removed or remains inside the bridge.
Diese Art der Verlegung einer Brücke ist relativ material- und personalaufwendig. Sie bedarf besonderer Einrichtungen (Rollenböcke, Gegengewicht etc.), die am Ufer aufgestellt werden müssen. Für die Verlegung ist in der Regel auch ein Fahrzeug erforderlich und während dieser Zeit gebunden. Das Fahrzeug wird u.a. als Einspannbock und Gegengewicht beim Vorschieben des Vorbauelementes verwendet.This type of laying a bridge is relatively expensive in terms of materials and personnel. It requires special facilities (roller stands, counterweight etc.) that have to be set up on the bank. A vehicle is usually also required for the installation and is bound during this time. The vehicle will be used as a clamp and counterweight when advancing the stem element.
Vorbauelemente, wie sie für zerlegbare Brücken nach dem Stand der Technik benutzt werden, erfordern ferner zusätzliche Transportkapazität.Stem elements, such as those used for dismantled bridges according to the prior art, also require additional transport capacity.
Voraussetzung für die Brückenverlegung mit Vorbauelementen ist, daß der Untergurt des Fahrbahnträgers glatte Flächen zum Auflagern auf Rollen der Rollenböcke hat.A prerequisite for laying bridges with stem elements is that the lower flange of the carriageway girder has smooth surfaces for bearing on rollers of the roller stands.
Aufgabe der Erfindung ist es, eine handbaubare Grabenbrücke, je nach erforderlicher Spannweite, bestehend aus einem oder zwei Spurträgerpaaren, bei der die mit Abstand parallel angeordneten Spurträger durch Spurstangen verbunden werden, deren einzelne Brückenelemente von geringem Gewicht sind, die in einfachster Weise zusammengebaut und ohne Beanspruchung von Fahrzeugen verlegt werden kann. Der Zeit- und Materialaufwand für die Verlegung der Brücke soll möglichst gering sein.The object of the invention is to provide a hand-built trench bridge, depending on the required span, consisting of one or two pairs of track carriers, in which the spaced parallel track carriers are connected by tie rods, the individual bridge elements of which are light in weight, which can be assembled in a simple manner and without Stress of vehicles can be relocated. The time and material required to lay the bridge should be as low as possible.
Die Erfindung löst diese Aufgaben in der Weise, wie es die Merkmale in den Patentansprüchen angeben.The invention achieves these objects in the manner indicated by the features in the claims.
Die handbaubare Grabenbrücke nach der Erfindung besteht nur aus wenigen Teilen, nämlich bei einer Brücke mit einer Spannweite von etwa 5 Metern nur aus einem Spurträgerpaar, das durch Spurstangen verbunden ist.The hand-built trench bridge according to the invention consists of only a few parts, namely in the case of a bridge with a span of about 5 meters, only one pair of track carriers, which are connected by tie rods.
Bei dieser 5 m-Brücke wird die gelenkige Rampe des Spurträgers ebenfalls wie die feste Rampe als Auffahrrampe benutzt.With this 5 m bridge, the articulated ramp of the track carrier is also used as the access ramp like the fixed ramp.
Für eine aus zwei Spurträgerpaaren bestehende Grabenbrücke mit entsprechend größerer Spannweite (10 m und mehr), werden gleiche Spurträger verwendet wie bei der Grabenbrücke geringer Spannweite, d.h. es werden zwei Spurträger mit ihren Rampenspitzen gekuppelt, nämlich die feste Auffahrrampe mit der gelenkigen Rampe des anderen Spurträgers.For a trench bridge consisting of two pairs of track supports with a correspondingly larger span (10 m and more), the same track supports are used as for the trench bridge with a narrow span, i.e. two track supports are coupled with their ramp tips, namely the fixed ramp with the articulated ramp of the other track support.
Die Verlegung der Grabenbrücke erfolgt nach dem erfindungsgemäßen Verfahren in entsprechenden Verfahrensschritten von Hand. Das Gewicht der Brückenteile ist, da es sich um eine Aluminium-Konstruktion handelt, relativ gering. Ein erfindungsgemäßer Spurträger von etwa 5 m Länge wiegt z.B. nur eta 160 kg.The trench bridge is laid by hand using the method according to the invention in corresponding method steps. The weight of the bridge parts is relatively low since it is an aluminum construction. A track carrier of approximately 5 m length according to the invention weighs e.g. only about 160 kg.
Die Verlegung einer 10 m-Grabenbrücke erfordert 5 bis 6 Mann. Die Verlegezeit für den gekuppelten Spurträger von etwa 10 m Länge dauert 10 Minuten einschließlich Vorbereitungszeit für das Verlegen.The laying of a 10 m trench bridge requires 5 to 6 men. The laying time for the coupled track carrier of about 10 m length takes 10 minutes including preparation time for laying.
Für die Verlegung und den Rückbau der Grabenbrücke wird nach der Erfindung ein spezielles Verlegegeschirr verwendet. Der Rückbau der Brücke ist von beiden Uferseiten möglich.For the laying and dismantling of the trench bridge according to the invention, special laying dishes are used. The bridge can be dismantled from both sides.
Fahrzeuge werden lediglich zum An- und Abtransport der Spurträger und des Verlegegeschirrs benötigt. Während des Zusammenbaus und der Verlegung der Grabenbrücke können Fahrzeuge anderweitig eingesetzt werden.Vehicles are only needed to transport the track carriers and the crockery in and out. Vehicles can be used for other purposes during the assembly and laying of the trench bridge.

Der Spurträger (1) ist eine Aluminium-Konstruktion und hat im Ausführungsbeispiel nach Fig. 1 eine Länge von 5 m und eine Höhe von nur 25 cm.The track carrier (1) is an aluminum construction and in the exemplary embodiment according to FIG. 1 has a length of 5 m and a height of only 25 cm.
An einem Ende weist der Spurträger (1) eine feste Auffahrrampe (2) auf, während das andere Ende des Spurträgers als gelenkige Rampe (3) ausgebildet ist.At one end the track carrier (1) has a fixed ramp (2), while the other end of the track carrier is designed as an articulated ramp (3).
An die Spitze der festen Auffahrrampe (2) ist ein Scharnierteil (5) angeschweißt.A hinge part (5) is welded to the top of the fixed ramp (2).
Die gelenkige Rampe (3) ist mit dem Spurträger (1) durch ein Scharniergelenk verbunden (Fig.4 und 5), das sich an der Unterseite des Spurträgers befindet. Das Scharniergelenk wird durch an Spurträger und Rampe angeordnete Scharnierteile (5, 6) und einen Scharnierbolzen (7) gebildet.The articulated ramp (3) is connected to the track carrier (1) by a hinge joint (Fig. 4 and 5), which is located on the underside of the track carrier. The hinge joint is formed by hinge parts (5, 6) arranged on the track carrier and ramp and a hinge pin (7).
An dem Spurträger (1) ist zur gelenkigen Rampe (3) hin ein klappbares Fahrbahnstück (8) angeordnet. Sofern die gelenkige Rampe (3) als Auffahrrampe (Fig.5) benutzt werden soll, ist das klappbare Fahrbahnstück (8) hochgeklappt, so daß die Lücke der Fahrspur zwischen der gelenkigen Rampe (3) und der Fahrbahnspur des Spurträgers (1) überbrückt wird. Das Fahrbahnstück (8) legt sich dabei auf den Vorsprung (9) der gelenkigen Rampe (3).A foldable track section (8) is arranged on the track carrier (1) towards the articulated ramp (3). If the articulated ramp (3) is to be used as an access ramp (Fig. 5), the foldable lane section (8) is folded up so that the gap in the lane between the articulated ramp (3) and the lane of the track carrier (1) is bridged . The track section (8) lies on the projection (9) of the articulated ramp (3).
In dieser Form mit zwei Auffahrrampen kann der Spurträger für die Errichtung einer Grabenbrücke kleiner Spannweite (z.B. 5 m) verwendet werden, die aus einem Spurträgerpaar besteht (Fig.1 und 2).In this form with two ramps, the track carrier can be used to build a trench bridge with a small span (e.g. 5 m), which consists of a pair of track carriers (Fig. 1 and 2).
Für eine Grabenbrücke größerer Spannweite (z.B. 10 m) werden für jede Fahrspur zwei hintereinander gekuppelte Spurträger (1) benötigt (Fig. 3). Das Aneinanderkuppeln geht in der Weise vonstatten (Fig. 4), daß ein Spurträger (1) mit dem Ende, das die gelenkige Rampe (3) enthält, auf die feste Rampe (2) eines anderen Spurträgers gelegt wird. Die feste Rampe (2) des zweiten Spurträgers weist an der Rampenspitze ein Scharnierteil (5). Die feste Rampe (2) wird mit Hilfe des Scharnierbolzens (7), der durch die Rundlöcher der Scharnierteile (5, 6) gesteckt wird, mit der gelenkigen Rampe (3) gekuppelt. Das klappbare Fahrbahnstück (8) hängt dabei senkrecht nach unten, so daß die Fahrspur des Spurträgers (1) mit der Fahrspur der gelenkigen Rampe (3) eine Ebene bildet.For a ditch bridge with a larger span (e.g. 10 m), two track carriers (1) coupled one behind the other are required for each lane (Fig. 3). Coupling is carried out in such a way (Fig. 4) that a track carrier (1) with the end containing the articulated ramp (3) is placed on the fixed ramp (2) of another track carrier. The fixed ramp (2) of the second track carrier has a hinge part (5) at the ramp tip. The fixed ramp (2) is coupled to the articulated ramp (3) with the help of the hinge pin (7) which is inserted through the round holes in the hinge parts (5, 6). The foldable track section (8) hangs vertically downwards so that the lane of the track carrier (1) forms a plane with the lane of the articulated ramp (3).
In Fig. 2 erkennt man eine aus einem Spurträgerpaar bestehende Grabenbrücke kurzer Spannweite. Die beiden Spurträger (1) sind in Abstand nebeneinander angeordnet und durch Spurstangen (4), die seitlich an den Wangen der Spurträger befestigt werden, verbunden.2 shows a trench bridge consisting of a pair of track carriers and having a short span. The two track supports (1) are arranged next to each other at a distance and connected by tie rods (4), which are attached laterally to the cheeks of the track supports.
Die Montage und der Verlegevorgang der Grabenbrücke sind in den Fig. 6 - 12 veranschaulicht.The assembly and laying process of the trench bridge are illustrated in FIGS. 6-12.
Für eine Grabenbrücke größerer Spannweite, im Ausführungsbeispiel eine 10-m-Brücke, werden zwei Spurträgerpaare benötigt.Two pairs of track supports are required for a ditch bridge with a larger span, in the exemplary embodiment a 10 m bridge.
Die beiden Spurträger (1) einer Fahrspur werden quer zur Fließrichtung des Flusses (21) auf den Uferboden (20) gelegt, wobei der Spurträger (1), dessen gelenkige Rampe (3) als Auffahrrampe vorgesehen ist, mit der Fahrbahnseite nach unten gelegt wird. Der zweite Spurträger (1) wird sodann mit seiner Fahrbahnseite nach oben auf den ersten Spurträger gelegt. Die beiden übereinander liegenden Spurträger (1) werden mittels Scharnierbolzen (7) gekuppelt, wie zuvor bereits beschrieben.
Die Kuppelstelle der beiden Spurträger befindet sich in vom Fluß (21) abgewandter Richtung.The two track carriers (1) of a lane are placed transversely to the direction of flow of the river (21) on the bank floor (20), the track carrier (1), the articulated ramp (3) of which is provided as a ramp, being placed with the road side down . The second track carrier (1) is then placed on the first track carrier with its side facing upward. The two superimposed track supports (1) are coupled by means of hinge bolts (7), as previously described.
The coupling point of the two track supports is in the direction facing away from the river (21).
Die Spitze der gelenkigen Auffahrrampe (3) des unten liegenden Spurträgers (1) ist in ein zuvor am Ufer (20) mittels Erdnägeln (11) verankertes Kipplager (10) eingeführt (Fig. 6 und 7), das sich um den Ankerbolzen (12) bewegen kann.The tip of the articulated ramp (3) of the track carrier (1) below is inserted into a tilting bearing (10) previously anchored on the bank (20) by means of pegs (11) (FIGS. 6 and 7), which is arranged around the anchor bolt (12 ) can move.
Hinter den beiden Spurträgern (1) wird eine Stützplatte (14) mittels Erdnägeln (11) im Boden (20) befestigt und sodann wird die zweibeinige Stütze (13) in die Stützplatte (14) eingehängt.Behind the two track supports (1), a support plate (14) is fastened in the floor (20) by means of pegs (11) and then the two-legged support (13) is suspended in the support plate (14).
Mit Abstand von der Stütze (13) wird eine Ankerplatte (16) mittels Erdnägeln (11) im Boden (20) verankert.At a distance from the support (13), an anchor plate (16) is anchored in the ground (20) by means of pegs (11).
Zur weiteren Vorbereitung der Brückenverlegung wird ein Zugseil (17) mittels Ringschraube (18) am oberen Spurträger (1) und an der Stütze (13) befestigt.To further prepare for the laying of the bridge, a traction cable (17) is attached to the upper track carrier (1) and to the support (13) using an eyebolt (18).
Der Seil-Flaschenzug (19) wird in die Ankerplatte (15) und in die Stütze (13) eingehängt. Schließlich werden die beiden Halteseile (16), die zuvor auf dem Boden (20) mittels Erdnägeln (11) befestigt wurden, in den unteren Spurträger (1) eingehakt.The rope pulley (19) is suspended in the anchor plate (15) and in the support (13). Finally, the two tethers (16), which were previously attached to the floor (20) by means of pegs (11), are hooked into the lower track carrier (1).
Damit sind die Vorbereitungen, die für geübtes Personal nur sehr wenig Zeit in Anspruch nehmen, abgeschlossen.This completes the preparations, which take very little time for experienced personnel.
Das Verlegen der Brücke beginnt mit dem gemeinsamen Aufrichten der beiden Spurträger (1) von Hand. Dazu werden vier Mann benötigt. Diese Arbeit ähnelt dem Aufrichten einer Leiter. Die Spurträger (1) sind dabei im Kipplager (10) gegen Wegrutschen gesichert. Der fünfte Mann hält während des Aufrichtens der Spurträger das Zugseil (17) mit dem Flaschenzug (18) auf Spannung.The laying of the bridge begins by erecting the two track supports (1) together by hand. Four men are needed for this. This work is like raising a ladder. The track carriers (1) are secured in the tilting bearing (10) against slipping. The fifth man holds the traction cable (17) with the pulley (18) under tension while the track supports are being raised.
Sind die Spurträger (1) bis etwas über 90 Grad aufgerichtet (Fig. 10), beginnt das selbsttätige Entfalten der Brücke. Dazu wird das Seil des Flaschenzuges (19) langsam nachgelassen. Für die Bedienung des Flaschenzuges ist anfangs ein Mann nötig, der im weiteren Verlauf des Verlegevorgangs durch einen zweiten Mann aus der Aufrichtegruppe verstärkt wird. Beim Rückbau der Brücke werden zu Beginn zwei bis drei Mann benötigt.When the track supports (1) are up to a little over 90 degrees (Fig. 10), the bridge automatically unfolds. To do this, the rope of the block and tackle (19) is slowly released. To operate the pulley system, one man is required at the beginning, who is then reinforced by a second man from the erection group as the laying process progresses. When dismantling the bridge, two to three men are needed at the beginning.
Das Entfalten der Brücke zeigt. Fig. 11.The unfolding of the bridge shows. Fig. 11.
Dieser Vorgang des Entfaltens beginnt mit dem Absenken des zunächst am Ufer unten liegenden Spurträgers . Gleichzeitig wird der zunächst oben liegende Spurträger angehoben. Das Entfalten der Grabenbrücken-Spurträger geht durch weiteres Nachlassen am Seil des Flaschenzuges (19) in den selbsttätigen Vorgang des Streckens (Fig. 12) über. Dabei legen sich die gekuppelten Spurträger (1) auf das jenseitige Ufer (20) ab.This process of unfolding begins with the lowering of the track carrier, which is initially on the bank below. At the same time, the track carrier initially on top is raised. Unfolding the trench bridge track carrier changes to the automatic stretching process (Fig. 12) by further slackening on the rope of the pulley block (19). The coupled track carriers (1) lay down on the other side bank (20).
Nachdem die eine Fahrspur der Grabenbrücke verlegt worden ist, wird der Verlegevorgang bei der parallel anzuordnenden zweiten Fahrspur in gleicher Weise wiederholt. Die beiden Spurträgerpaare (1) werden anschließend durch Anbringen von Spurstangen (4) und gegebenenfalls durch zusätzliche Seilverspannung miteinander verbunden.After the one lane of the trench bridge is laid the laying process is repeated in the same way for the second lane to be arranged in parallel. The two pairs of track carriers (1) are then connected to each other by attaching tie rods (4) and, if necessary, by additional cable bracing.
Soll die Grabenbrücke wieder abgebaut werden, so geschieht dies ebenfalls mit dem Verlegegeschirr und zwar in umgekehrter Reihenfolge. Der Rückbau der Grabenbrücke ist von beiden Uferseiten aus möglich.If the trench bridge is to be dismantled again, this is also done with the laying crockery in reverse order. The demolition bridge can be dismantled from both sides.
Das Verlegen der kurzen, aus nur einem Spurträgerpaar bestehenden Grabenbrücke geschieht sinngemäß wie das Verlegen der aus zwei Spurträgerpaaren bestehenden Grabenbrücke.The laying of the short trench bridge, which consists of only one pair of track supports, is carried out in the same way as the laying of the trench bridge, which consists of two pairs of track supports.
