Abstract

The modular bridge (1) consists of multiple similar bridge segments (2). The individual bridge segments are designed in a plate-shape manner and are connected together in a detachable manner. The C-profiles (5) are placed on the side edges of the bridge segments for reinforcing the modular bridge. The C-profiles are moved in order to overlap the bridge segments adjacent to the front sides (7,8) facing each other.

Description

The The invention relates to a module bridge having a plurality of identical ones narrow segments.

to Preservation of tactical / operational mobility is attacking armed forces on special vehicles for overcoming terrain cuts and waters back to about 25 m wide. These Special vehicles, usually bridge-layer tanks or vehicles, are capable of using the laying device a bridge unfold and place on the jobsite. These module bridges are divided into larger modules to transport to simplify on the vehicle.

In the not before published DE 10 2007 001 778.4 a bridge laying system for longer bridge modules or bridge sections is described. A feed module integrated on the base vehicle / carrier has a main boom (laying bar) attached to it. When advancing the laying system, the feed module is moved to folding torque arms, whereby a large proportion of the reaction forces is introduced during the laying process in the bow area.

Bridge modules of several meters in length, which are stacked horizontally on a carrier or laying vehicle and then connected to each other at the front end during the laying process, are further from the DE 10 2004 016 983 B1 such as DE 10 1004 016 974 A1 known.

Of the present invention is based on the object, a laying bridge to reveal, which in a simple way with neighboring similar Make segments into a laying bridge, the individual bridge segments are much smaller Lengths may have as this in known Bridge modules is the case.

These The object is achieved by the features of claim 1 or 9 solved. Further, particularly advantageous Embodiments of the invention disclose the subclaims.

The Invention is based essentially on the idea of the laying bridge into smaller segments or segments (segment bridges or segments) Link bridges), the individual segments or links then are identical except for any ramps, so that Cost advantages arise in production, in use in the event of damage to individual components Segment, easy replacement is possible (redundancy), facilitates handling due to the lower weight and in addition alternative loading options by vertical Stack or roll up to provide. Each segment of the deployable Bridge preferably has the required bridge width, but only a fraction of the maximum bridge length or a known bridge module. Advantageously, a Division into 1 to 2 m wide segments.

The Bridge is made of relatively short, plate-shaped Bridge segments to assemble, with the individual Bridge segments are detachable from each other at the ends connected and to stiffen the bridge on the side edges the bridge segments C-profiles are postponed, which At the edge, cover the facing end faces of adjacent bridge modules.

When It has proven advantageous if the length of the individual C-profiles about the (in the direction of the longitudinal axis of the module bridge seen) length or width of a bridge segment corresponds so that the C-profiles in the axial direction by half a module bridge width are shifted.

Around a space-saving transport and a simple installation process To ensure the bridge, it has also proven to be advantageous proven when the individual bridge segments have a width, which correspond to the desired bridge width, but their length / width only chosen so is that the bridge segments also standing by a vehicle can be transported. It has a length or width of the bridge segments of about 1 to 2 m as proved particularly advantageous.

Further Details and advantages of the invention will become apparent from the following Based on figures explained embodiments. Show it:

1 the side view of a composite of three bridge segments bridge section of a module bridge according to the invention;

2 a top view of the in 1 illustrated bridge section;

3 a cross section through the bridge section along the in 2 with III-III designated cutting line and

4 a schematically illustrated laying vehicle when laying the module bridge according to the invention.

In the 1 and 2 is a bridge section with a 1 designated inventive module bridge shown. The bridge section is made up of identically constructed bridge segments 2 together, each one example Have a width L of, for example, 1.5 m.

The individual bridge segments 2 are plate-shaped and in a conventional manner releasably connected to each other end face. In a simple variant are front side at the upper edge of the bridge segment 2 a kind of hook arranged in the intended use of the bridge segment 2 a bolt engaged at the rear of a bridge segment which is similarly adjacent to one another 2 can engage. At the lower edge of the bridge segment 2 can be provided on the front side extending in the longitudinal direction of the bridge projection, which has a transverse bore into which can engage in the intended use of the bridge segment arranged in the rear-side region of the front side adjacent bridge segments movable safety pin (not shown).

According to the invention it is now provided that for stiffening the module bridge 1 on the two margins 3 . 4 the bridge segments 2 C-sections 5 . 6 ( 3 ) are also applied or pushed, which each have the edge sides facing each other end faces 7 . 8th adjacent bridge segments 2 can cover. The profiles 5 . 6 should be slightly biased to drop off the page margin 3 . 4 to prevent. Alternatives may include rubber-like elements attached to the sidewalls 3 . 4 attack. The elements can either be considerably shorter than the length of the profiles 5 . 6 or in sections on the profiles 5 . 6 to be appropriate.

The length of the individual C-profiles 5 . 6 is approximately the width L of a bridge segment 2 to choose, so the C-profiles 5 . 6 after the frontal connection of adjacent bridge segments 2 in the direction of the longitudinal axis 100 the module bridge 1 or the bridge segments 2 can be moved by half a segment width.

It has proved advantageous if the C-profiles 5 . 6 already on the margins 3 . 4 of the respective bridge segment 2 are applied.

The following is a possible installation process of the module bridge according to the invention 1 with the help of 3 explained in more detail:
First, a first bridge segment 2 a segment magazine 9 a corresponding laying vehicle 10 For example, manually removed and in a support 20 introduced with an internal lock release. In this case, for example, a disc not shown below the bridge segment 2 rotated to lock by about 90 °, which, for example, bolts in transverse bores of the other bridge segment 2 (not shown) are inserted. After that, the C-profiles 5 . 6 shifted by half a segment width L, which is realized by hand or with the help of an appropriate tool.

The individual widths of the bridge segments 2 then sum up the length of the required laying bridge 1 , Due to the identical structure of the bridge segments 2 can also segments 2 different widths L can be used, whereby the length of the laying bridges can be individually adapted to local requirements. The easy transport of different widths L is caused by the standing of the segments 2 in the segment magazine 9 of the vehicle 10 guaranteed.
