BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates in particular to transportable crossing structures, which are intended for so-called heavy vehicles, such as armored vehicles, to cross gaps.

0002

PRIOR ART AND PROBLEM TO BE SOLVED BY THE INVENTION In order for so-called heavy vehicles to cross gaps or other passages between two raised edges, it is necessary not only to have a special rapid laying ability, but also to have a light weight, which makes it easier to transport and use. It also requires a transverse structure with

[0003] These requirements for lightness and ease of handling are due to the weight of the vehicles using these transverse structures.
Contrary to the qualities of durability, mechanical strength and high resistance.

[0004] These transverse structures are generally either scissor-shaped transverse structures or simple transverse structures in the form of several parts that can abut each other.

Scissor-type transverse structures consist of two or three elements, which are elongated by rotation in a vertical plane about a common axis of the two elements.

[0006] After deployment, these transverse structures can be laid down by jibs or manipulators.

In the case of simple transverse structures, the parts are transported one on top of the other and then moved in translation by a manipulator which, after locking the parts, lays down the transverse structure thus constituted. It's also helpful to do.

Hitherto, scissor-type or simple transverse structures have generally been constructed of welded metal beams or lattice structures of large cross-section, resulting in significant weight of the transverse structure and This makes it less easy to put these transverse structures in place.

Moreover, the weight of these crossing structures requires the use of high powered transport and handling vehicles.

[0010] It is now known that handling times and various mounting operations for loading and unloading are major factors, especially within the framework of rapid operations.

[0011] It is therefore an object of the present invention to provide a transverse structure for bridging gaps, which is able to satisfy the qualities of durability, strength, mechanical resistance and lightness.

SUMMARY OF THE INVENTION The subject of the invention comprises at least a pair of parallel parts connected to each other to form a track, each part being placed next to each other and fixed to each other. , in a transportable transverse structure for bridging gaps, consisting of multiple modules made of lightweight materials of low density and high resistance, each module connects end-to-end and connects one of the above parts. A transversal structure characterized in that it is constituted by a series of boxes installed longitudinally and fixed to each other.

According to another feature of the invention, each box placed end-to-end in the length direction is a series of boxes placed next to each other in the width direction of said boxes and fixed to each other; It is made up of. - The box consists of thin walls that can be locked together. - The box is constituted by at least one thin U-shaped wall that can be locked to the wall of an adjacent box. - The module rests on a substrate made of lightweight material with low density and high resistance. - Lightweight materials with low density and high resistance are composite materials. - The composite material consists of carbon fibers. - The composite material consists of glass fibers. - The composite material has a honeycomb structure.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention will be better understood from the following description of embodiments of the invention with reference to the accompanying drawings, in which: FIG.

The transverse structure shown in FIG.
The parts of each pair are connected to each other by a transverse piece 2.

In order to bridge the gap, pairs of parts 1 can be installed end-to-end to form at least one track through which a vehicle can pass.

Each component 1 is provided at each end with an apron 3 which constitutes an inclined plane for the approach of the vehicle onto said component and which ensures a high stability of the assembly as a whole. ing.

The component 1 comprises a plurality of modules 10a, 10b, 10c, etc. (see FIGS. 1 and 2) placed next to each other and fixed to each other by suitable means (not shown).
It is made up of.

Each module 10a, 10b, 10c, etc. is in the shape of a parallelepiped, the upper surface of which is slightly inclined to form a continuous curved profile.

The modules 10a, 10b, 10c, etc. are mounted on a substrate 4 (FIG. 2).

According to a first embodiment shown in FIGS. 2 and 3, each module 10a, 10b, 10c, etc. has two thin vertical walls 12a, 12b and two thin horizontal walls 13.
It is constituted by a box 11 in the longitudinal direction consisting of a and 13b.

Wall portions 12a, 12b and 13a, 13b
can be locked together, placed next to each other and assembled by any suitable means.

[0023] Also, each module 10a, 10b, 10
c, etc. are preferably constituted by a series of boxes 11 placed adjacent to each other in the width direction of the component 1 and fixed to each other by suitable means.

According to a second embodiment shown in FIG. 4, each module 10a, 10b, 10c, etc. is a box installed end to end in the length direction of the component 1 and fixed to each other by suitable means. It is composed of a series of

According to the third embodiment shown in FIG.
Or 14 is constituted by a thin U-shaped wall 15 which can be locked onto the wall of an adjacent box.

In this case, the box 11 or 14 of the lateral end module 10a is closed by a thin vertical wall 16 which rests on the U-shaped wall 15 constituting the box.

Similarly, the box 11 or 14 rests on the substrate 4.

According to yet another embodiment, each module consists of a box 1 installed end-to-end along the length of the component.
4 and a series of boxes 11 placed next to each other in the width direction of the parts, said boxes being fixed to each other by suitable means.

In all the examples shown in the figures, module 1
The walls of the box 11 or 14 constituting 0a, 10b, 10c etc. and the substrate 4 are made of a lightweight material of low density and high resistance.
