*******************************************************
ETAT DE LA TECHNIQUE
A l'heure actuelle différents systèmes existent avec chacun leurs inconvénients. The present invention relates to a device for the continuous crossing of ravines or rivers of approximately 30 meters wide. It is initially planned for the Genius weapon in the French Army.

************************************************** *****
STATE OF THE ART
At present different systems exist with each their disadvantages.

 The first of these systems is a system entirely implemented by hand, but which requires a lot of personnel and time, especially if you want to make heavy convoys pass.

 The second of these systems is a system which requires the prior installation of a beam system on which the elements would be positioned one after the other.

 The third of these systems requires the need to move the telescopic crane on itself, which places the elements one after the other in advance. Human activity results from elements that are cantilevered.

 The fourth of these systems is a series of elements which are deposited in water, in order to assemble them to each other. The problem is that it only serves to cross watercourses and that it is impossible to implement in the case of strong currents.

 The fifth of these systems, in addition to the fact that it is only fluvial, it can only cross loads limited in tonnage.

 The sixth of these systems requires a large clearance in height to deploy its track folded in half.

************************************************** *****
PROPOSED INVENTION
This invention therefore makes it possible to cross dry and wet breaches of about 30 meters in width, in all weather and in all conditions, in both heavy tanks and light vehicles.

<Desc / Clms Page number 2>

The invention is a two-stage crossing system (hereinafter referred to as BRIDGE). It is modular [board N 22]. The modules are put in place by pushing. It is a continuous crossing system. There is no break in charge. It can be disconnected from the carrier vehicle. The vehicles pass on the higher platform (which does not have any vacuum on all the useful width which is approximately 4 meters) and the troop or two wheels can pass on the lower platform.

 All the systems mentioned in the STATE OF THE ART section are constructed of steel or an alloy (ferrous or not). These constituent materials have a high density (around 7.8) and age poorly. The construction of spare parts for these materials requires significant production costs (tools, equipment, machine tool).

 The invention is based on the construction of a system which could be made of composite materials. This material is as solid as steel, lighter and with a production cost which can be much lower.

- commodité de manutention et de transport, - commodité d'assemblage et de réparation (adhésion par collage ou attaches mécaniques, (boulons, verrous...) - commodité d'intégration de diverses fonction (inserts par exemple) et de pré-assemblage. Composite materials also have several advantages: they do not rust,

- convenience of handling and transport, - convenience of assembly and repair (adhesion by gluing or mechanical fasteners, (bolts, latches ...) - convenience of integration of various functions (inserts for example) and pre-assembly .

<Desc / Clms Page number 4>

 - make lower loads pass over a greater length.

- Be smaller or larger depending on what you want to pass on the lower platform and on the upper platform ****************** **************************************
As a non-limiting example, the MODULE will have a length of 4.40 m and a useful width of 4.40 m.

The front view of the MODULE is represented by [Plate N 10]. The side view is represented by [Plate N 11]
The architecture of the amounts of ELEMENTS B could meet the rule of d: [Plate N 11] [Plate N 23].

************************************************** *******
PHYSICO-CHEMICAL COMPOSITION OF THE ELEMENTS
All the constituent elements of the BRIDGE may be made of composite materials.

 The mechanical behavior of composites is defined by the rules of composite mechanics. It is not possible to specify in general the properties of the material.

Indeed the characteristics of the finished part depend on each of the components, their geometry, their arrangement and also the manufacturing process. Each piece therefore constitutes a particular product. Properly studied, a composite material can be capable of much more than we think.

 The material chosen could consist of the following products: standard glass fibers (approximately 50% of the total weight), this is the reinforcement.

 Unsaturated polyester, a thermosetting resin, is the matrix.

 The effectiveness of a fiber (reinforcement) in reinforcing a matrix is measured by the quality of the bond that is established between the two. The effectiveness of this connection will depend on the stress transfers from the matrix to the reinforcement, therefore the levels of mechanical performance which will be reached.

<Desc / Clms Page number 5>

 It is the role of the sizing (chemical treatment of the fibers) and more particularly of the bridging agent that to establish and maintain this reinforcement / matrix connection.

Fillers, such as glass microspheres for example, may be included in the resin to improve its performance: reduction in shrinkage,
Greater fluidity increased resistance: a to abrasion, m to scratching, a to aggression by chemicals, a to the penetration of stains, - reduces the penetration of water, with fine microspheres , improvement of the surface appearance.

 The microspheres will be full, coated with a coupling agent, and their proportion would be around 30% of the reinforcement.

************************************************** *******
PRODUCTION OF ELEMENTS
The realization could be done by a process which would offer the best performances as well in traction as in bending. This would be done in a single step from the components, matrix and reinforcement. The process used could be contact molding. Its principle is as follows:
The mold coated with a release agent, receives the surface layer or gel coat (this may have a contribution of glass microspheres in order to provide greater resistance to abrasion), then reinforcement under form of successive layer of mat or fabric which is impregnated, generally manually, with resin (matrix) (to which there have been included microspheres of glass provided) until the desired thickness is obtained. The polymerization can be carried out at ordinary temperature or can be accelerated by heating.

 Contact molding is a relatively easy operation and can be costly in material, but it

<Desc / Clms Page number 6>

 requires skilled labor to obtain satisfactory characteristics.

The BRIDGE not being for the moment a work to be produced in large series, the production could not suffer from the slow rate of this manufacturing process.

************************************************** *******
ELEMENT PUSHING
The elements constituting the MODULES could be conveyed by separate trucks, then assembled on the PUSH TRUCK.

la centrale hydraulique pour LA GRUE et les vérins, la source d'énergie en 220 Volts et éventuellement en 380 Volts, le système de poussage par vérins, et les treuils - outillage divers (élingues, manilles, cordages,...)
La ZONE 2 qui pourrait être équipée des 2 chemins de roulement cylindrique (61). C'est cette zone qui reçoit les éléments en montage qui lui sont apportés par LA GRUE. Elle ne peut recevoir qu'un seul ELEMENT A à la fois. A titre d'exemple non limitatif cette zone pourra avoir une longueur de 6 mètres environ. The pushing system would consist of the following materials:
The platform of the PUSH TRUCK itself. On this one we can distinguish 4 zones [Plate N 28]
ZONE 1 is the zone which is intended to receive all the motorization of the pushing comprising inter alia [Plate

? 31]: - the crane with telescopic arm (81), hereinafter referred to as THE CRANE, - The Energy power station (80) comprising: the generator,

the hydraulic power station for THE CRANE and the jacks, the source of energy in 220 Volts and possibly in 380 Volts, the pushing system by jacks, and the winches - various tools (slings, shackles, ropes, ...)
ZONE 2 which could be fitted with 2 cylindrical raceways (61). It is this area which receives the assembly elements brought to it by LA GRUE. It can only receive one ELEMENT A at a time. By way of nonlimiting example, this zone may have a length of approximately 6 meters.

 ZONE 3 could be equipped with 2 additional cylindrical raceways (61) to counter the tilting of the bridge. These two additional raceways will be fixed to the platform (65), by means of the part (64) [Plate N 17]. This zone must withstand the force due to the cantilevering of the system during pushing.

<Desc / Clms Page number 7>

 The effort is maximum at the time when the descent ramp put in the high position arrives on the arriving bank. By way of nonlimiting example, this zone could have a length of around 6 meters.

 ZONE 4 has the same characteristics as ZONE 1. it is intended to receive the BRIDGE when it returns to the platform of the PUSH TRUCK, for disassembly.

 The PUSH TRUCK could be equipped with: 4 cylinders (75) [Plate N 29] [Plate N 30]. heavy tonnage (approximately 500 tonnes), double-acting, retracted rod height less than 800 mm and a stroke between 250 and 300 mm.

They will be placed in a vertical position and will be equipped with an oscillating head. They will be designated in what follows by CYLINDERS Z. in (76) is the junction which would make it possible to lower the pistons of the cylinder. In (77) is the junction that would lift the piston of the cylinder.

These cylinders will have several uses:
Before pushing, the horizontality of the platform will be ensured by the operation of the 4 Z-JACKS simultaneously.

 - when pushing the whole platform of the PUSH TRUCK will be raised at its end on the breach side, so that the platform makes an angle with respect to the horizontal (up to about 20 angles) [Plate N 29] [Plate N 30]. They can also, if necessary, tilt the platform by a few tens of minutes of angle in the opposite axis. This system will allow, among other things, to raise the head of the BRIDGE during pushing in order to counteract its natural bending.

 - when the head of the BRIDGE arrives on the arriving bank, they will be used to lower the BRIDGE onto its guide rails. [Plate N 34]. raise or lower the platform of the PUSH TRUCK in order to facilitate the arrival of the MODULES in ZONE 2 with a view to dismantling the BRIDGE.

 The maximum pushing speed of SETS D could be around 5 meters per minute (0.3 Km / h)

ROADWAYS
These will be double roller chain translation bearings on a cylindrical track and bearing with V-shaped sole and clevis. They are made up of: - 2 cylindrical tracks on each side of the platform of the PUSH TRUCK [Plate N017]. One is at the level of the platform (65), another one can be higher in height. These 2 tracks are fixed on a support (64). The fixing of the tracks themselves will be done using a jointing with plastic cement (62). As it dries, it will form a solid support offering significant resistance to compression (850 kg / cm2). Cement retaining brackets (63) will be placed on each side of the raceway. They will be targeted on the support (64).

<Desc / Clms Page number 9>

- The support will be firmly bolted to the platform (65) of the PUSH TRUCK, by HR bolts (High
Resistance) plus their washers.

 - Roller chain translation bearings (55) [Plate N 15] [Plate N 16], which are designed for rectilinear movements will be used. At the locations (12) the holes (56) of the parts (55) will adjust to the fixing points (13) located on the part (01) [NOOl board].

************************************************** *******
OPERATING PRINCIPLE OF ROLLER GUIDANCE
The bearing for cylindrical track is a roller bearing running endlessly, with rectilinear displacement, without friction on treated and rectified shafts.

 It includes 3 main parts [Plate N 16] - the inner core or raceway (60), - the roller chain (59), - the eccentric pin (57).

 In operation, the bearings which are fixed on the load to be translated, roll freely on the concave roller chains (59) which bear on the hard treated cylindrical track (61) [Plate N 17]. These will be supported at their lower part by plastic cement (62). By rotation of the eccentric pin (57), the height of the roller bearing can be adjusted to compensate for variations in the lower part of the load and eliminate play between the different elements. After adjustment, the position is maintained by the locking screw (58).

DETAILED DESCRIPTION OF THE ELEMENTS CONSTITUTING THE BRIDGE
With reference to these plates, the different constituent parts of a MODULE are as follows:
ELEMENT A which consists of the following elements [Plate N'Ol]: o The plate (01) o The end reinforcements of (01) that are (02).

 These reinforcements may be made of stainless steel o The pins (07), integral with the plate (01), serve to embed the ELEMENTS B o The reinforcements (08) of the pins (07) [Plate N 24].

 They can be made of stainless steel.

Les quatre mortaises cylindriques (17) pourront recevoir les goupilles (36) [ Planche NO06 ] pour permettre la jonction avec un autres ELEMENT A. Four cylindrical reservations (04) [Plate N 01] are provided on the short sides of the plate (01). This is to allow the protection (02) to fit into (03). So that this embedding is complete, at each end of the plate (01), a

reservations all around will be made [Plate N 01]. The tenons (16) [Plate N 03] come to be embedded in the mortises (04). The four cylindrical mortises (17) can receive the pins (36) [Plate NO06] to allow the junction with another ELEMENT A.

<Desc / Clms Page number 12>

In (09) [Plate N 24] is the axis of assembly of the ELEMENTS B on the ELEMENTS A. At this location, a stainless steel tube (10) will serve as lost formwork during the molding of the assembly that could form the parts (01) and (07). After hardening, a reinforcement which could be made of molded stainless steel, of cylindrical shape (08) will protect the studs (07) against possible shocks. This reinforcement would then be welded to the tube (10).

 To unlock the pins that could be blocked, reservations for the vents (05) and (06) will be arranged under the tray (01) [Plate N 02].

 ELEMENT A and ELEMENT B can be assembled using a double action ball pin (11) which will be introduced at (09).

 For the assembly of two MODULES pins will be used (36). The assembly will be stiffened by HR bolts in (18).

 The two grooves (14) are over the entire length of (01) and over the entire width of (02) [Plate N 02]. This system could allow several ELEMENTS A to be superimposed on each other. During transport the size would be reduced.
