Description

La présente invention concerne un ponton flottant et, plus particulièrement, un ponton de débordement de navires, communément dénommé ras débordoir.The present invention relates to a floating pontoon and, more particularly, to an overflowing pontoon for ships, commonly known as an overflow bridge.

Ces pontons sont présents en grand nombre dans les ports. Mouillés le long des quais, ils permettent l'accostage des navires indépendamment du niveau de l'eau, ou bien là où il existe des rives de pente insuffisante pour un accostage direct. Ils sont également très utiles pour intervenir sur les coques.These pontoons are present in large numbers in ports. Wet along the quays, they allow ships to dock regardless of the water level, or where there are banks of insufficient slope for direct docking. They are also very useful for working on hulls.

Du point de vue mécanique, ils doivent être conçus de manière à pouvoir encaisser d'importants efforts latéraux de compression répartis sur leur longueur. A titre indicatif, pour le débordement d'un navire d'un déplacement d'environ 6.500 tonnes lors de son amarrage à quai, cet effort est estimé à environ 700 tonnes. D'autre part, les pontons se doivent bien entendu d'être parfaitement stables.From the mechanical point of view, they must be designed so as to be able to absorb significant lateral compression forces distributed over their length. As an indication, for the overflow of a ship with a displacement of around 6,500 tonnes when it is docked, this effort is estimated at around 700 tonnes. On the other hand, the pontoons must of course be perfectly stable.

Les pontons de débordement existants sont en acier et comportent un important système de raidissement fait de varangues, barrots, membrures, etc, ainsi que de cloisons transversales, elles-mêmes renforcées par des montants et des serres. Des trous d'homme dans le pont permettent l'accès aux divers compartiments pour la maintenance.The existing overflow pontoons are made of steel and have a large stiffening system made of verandas, beams, frames, etc., as well as transverse partitions, themselves reinforced by uprights and greenhouses. Manholes in the deck allow access to the various compartments for maintenance.

La maintenance est précisément le point sur lequel ces pontons posent problème : des visites de contrôle fréquentes dans les compartiments sont nécessaires et, pour la protection contre la corrosion, les peintures intérieure et extérieure doivent être renouvelées régulièrement. Ceci engendre des coûts importants.Maintenance is precisely the point on which these pontoons are problematic: frequent inspection visits to the compartments are necessary and, for protection against corrosion, the interior and exterior paints must be renewed regularly. This generates significant costs.

L'invention a pour but majeur de pallier cet inconvénient par la conception d'un nouveau ponton ayant les caractéristiques mécaniques requises, mais fait de matériaux composites quasi-insensibles à la corrosion marine.The main object of the invention is to overcome this drawback by designing a new pontoon having the required mechanical characteristics, but made of composite materials which are almost insensitive to marine corrosion.

Un autre but de l'invention est de prévoir pour ce nouveau ponton une structure de réalisation simple malgré des impératifs techniques sévères.Another object of the invention is to provide for this new pontoon a simple construction structure despite imperatives severe techniques.

A cet effet, le nouveau ponton en matériau composite est caractérisé en ce qu'il comprend :

  • une coque monobloc parallélépipédique ;
  • un pont recouvrant la coque ; et,
  • une structure de renfort interne constituée d'une pluralité d'éléments transversaux dont le profil a la forme générale d'un U inversé, lesquels éléments transversaux relient les parois latérales de la coque, fixés à celles-ci et au fond, et ont leur sommet formant appui pour le pont.
To this end, the new pontoon made of composite material is characterized in that it comprises:
  • a one-piece parallelepiped hull;
  • a deck covering the hull; and,
  • an internal reinforcement structure made up of a plurality of transverse elements, the profile of which has the general shape of an inverted U, which transverse elements connect the side walls of the shell, fixed to them and at the bottom, and have their top forming support for the bridge.

Ainsi, les éléments transversaux assurent la triple fonction de :

  • supporter le pont ;
  • rigidifier l'ensemble ;
  • conférer à l'ensemble la résistance nécessaire pour absorber les efforts latéraux de compression.
Thus, the transverse elements ensure the triple function of:
  • support the bridge;
  • stiffen the whole;
  • give the assembly the resistance necessary to absorb the lateral compression forces.

Dans une forme de réalisation préférée, les éléments transversaux comportent de plus à leur base, des ailes latérales dirigées vers l'extérieur, qui accroissent la raideur de leur partie inférieure, et par lesquelles ils sont collés au fond de la coque.In a preferred embodiment, the transverse elements further comprise at their base, lateral wings directed towards the outside, which increase the stiffness of their lower part, and by which they are glued to the bottom of the hull.

D'autres caractéristiques et avantages apparaîtront à la lecture de la description suivante faite en relation avec les dessins annexés dans lesquels :

  • la figure 1 est une vue en plan d'une forme de réalisation de ponton selon l'invention ;
  • les figures 2 et 3 sont respectivement une vue latérale pour moitié en coupe, et une vue de bout du même ponton ;

  • les figures 5 et 6 sont respectivement une vue de côté et une vue de bout d'un élément transversal ;
  • la figure 7 est une vue de détail illustrant d'une part comment sont assemblés la coque et le pont et, d'autre part, le montage de deux accessoires ; et,
  • la figure 8 est une autre vue de détail du montage d'un troisième accessoire.
Other characteristics and advantages will appear on reading the following description made in relation to the appended drawings in which:

  • Figure 8 is another detail view of the mounting of a third accessory.

Pour plus de clarté, les mêmes éléments portent les mêmes références sur toutes les figures.For clarity, the same elements are given the same references in all the figures.

Le ponton 1 représenté dans les dessins comprend essentiellement une coque 2 allongée de forme parallélépipédique, un pont 3 recouvrant la coque 2, et une structure interne de renfort consistant en une pluralité d'éléments transversaux 4 disposés à intervalles réguliers.The pontoon 1 shown in the drawings essentially comprises an elongated shell 2 of parallelepiped shape, a bridge 3 covering the shell 2, and an internal reinforcement structure consisting of a plurality of transverse elements 4 arranged at regular intervals.

Le pont 3 est équipé d'organeaux 5 répartis à sa périphérie entre des tronçons de cunette 6, figure 1, de pitons de levage 7 et de bittes d'amarrage doubles 8. Par ailleurs, deux lignes de défense 9 superposées ceinturent la coque 2.The deck 3 is equipped with members 5 distributed at its periphery between sections of the cunette 6, FIG. 1, lifting lugs 7 and double mooring bittes 8. In addition, two superimposed lines of defense 9 surround the hull 2 .

Cette dernière est réalisée dans un moule ayant la forme extérieure du ponton. Elle est constituée d'un composite monolythique verre-résine enduit extérieurement de gel-coat. Dans une forme de réalisation satisfaisante, le composite comprend dans la résine une pluralité de couches de sergé de verre entre deux couches de mat de verre.The latter is produced in a mold having the external shape of the pontoon. It consists of a monolithic glass-resin composite coated externally with gel-coat. In a satisfactory embodiment, the composite comprises in the resin a plurality of layers of glass twill between two layers of glass mat.

Le pont 3 est quant à lui un sandwich 30, figure 3, dont l'âme a une structure alvéolaire, par exemple de type nid d'abeille. La peau inférieure et la peau supérieure sont en un composite verre-résine, lequel, comme pour la coque 2, peut comporter plusieurs couches de sergé de verre entre deux couches de mat de verre. La peau supérieure est d'autre part recouverte d'un anti-dérapant.The bridge 3 is itself a sandwich 30, FIG. 3, the core of which has a honeycomb structure, for example of the honeycomb type. The lower skin and the upper skin are made of a glass-resin composite, which, as for shell 2, can comprise several layers of glass twill between two layers of glass mat. The upper skin is also covered with a non-slip.

Le pont 3 est préfabriqué sur moule avec bouge rectiligne de manière à présenter une pente transversale légère de chaque côté d'une bande médiane horizontale 3a, figure 1. Dans une mode de fabrication, la première peau et l'âme sont compactées sous vide. L'anti-dérapant est appliqué sur le pont après mise en place des accessoires.The bridge 3 is prefabricated on a mold with rectilinear movement so as to present a slight transverse slope on each side of a horizontal median strip 3a, FIG. 1. In one embodiment, the first skin and the core are compacted under vacuum. The anti-slip is applied to the deck after fitting the accessories.

Conformément à l'invention, les éléments 4 formant la structure interne de renfort on un profil en forme générale de U, ou encore de , à savoir qu'il présente deux ailes horizontales de base 4a, deux jambes rectilignes 4b de préférence légèrement inclinées l'une vers l'autre en dépouille, et un sommet également horizontal 4c. Dans le sens longitudinal, le sommet 4c est prévu avec bouge rectiligne identique à celui du pont, comme on peut le voir à la figure 5.In accordance with the invention, the elements 4 forming the internal reinforcement structure has a generally U-shaped profile, or else, namely that it has two basic horizontal wings 4a, two rectilinear legs 4b preferably slightly inclined towards one another in draft, and a also horizontal top 4c. In the longitudinal direction, the apex 4c is provided with rectilinear movement identical to that of the bridge, as can be seen in FIG. 5.

Les éléments 4 sont fabriqués sur un moule mâle. Avantageusement, ils sont en un même composite verre-résine que la coque 2, mais de préférence plus épais.The elements 4 are produced on a male mold. Advantageously, they are made of the same glass-resin composite as the shell 2, but preferably thicker.

Les éléments transversaux 4 sont collés au fond de la coque 2 par leurs ailes de base 4a, et à ses parois latérales par leurs extrémités. Comme montré à la figure 6, ces liaisons peuvent être renforcées par des éléments de corniérage tels que 10.The transverse elements 4 are glued to the bottom of the shell 2 by their base wings 4a, and to its side walls by their ends. As shown in FIG. 6, these connections can be reinforced by corniérage elements such as 10.

Les éléments 4 sont disposés dans la coque 2 à intervalles réguliers. Ecartés comme à la figure 3, ils délimitent entre eux des volumes identiques à leurs volumes internes, de sorte que l'ensemble des jambes 4a forme un entretoisement transversal uniformément réparti sur toute la longueur du ponton.The elements 4 are arranged in the shell 2 at regular intervals. Spaced apart as in FIG. 3, they delimit between them volumes identical to their internal volumes, so that the set of legs 4a forms a transverse bracing uniformly distributed over the entire length of the pontoon.

La structure interne de renfort est complétée par deux cloisons médianes longitudinales 11 entre le fond de la coque 2 et le pont 3, figure 4, réunissant respectivement le premier et le dernier élément 4 à la paroi d'extrémité voisine de la coque 2.The internal reinforcement structure is completed by two longitudinal central partitions 11 between the bottom of the hull 2 and the deck 3, FIG. 4, respectively joining the first and the last element 4 to the end wall adjacent to the hull 2.

Les éléments 4 servent également à l'appui du pont 3 qui repose par ailleurs sur le pourtour de la coque 2. La peau inférieure du pont 3 est collée sur le dessus des éléments 4. Quant à la liaison pont-coque, elle est illustrée à la figure 7 : il s'agit d'un collage entre le bord supérieur de la coque et la peau inférieure du pont, plus un corniérage périphérique désigné par le repère 12.The elements 4 also serve to support the bridge 3 which also rests on the periphery of the hull 2. The lower skin of the bridge 3 is glued to the top of the elements 4. As for the bridge-hull connection, it is illustrated in FIG. 7: this is a bonding between the upper edge of the hull and the lower skin of the deck, plus a peripheral corniérage designated by the reference 12.

Les figures 7 et 8 montrent comment sont fixés les principaux accessoires du ponton. Les organeaux 5 sont vissés à travers la paroi 30 du pont 3, dans des contre-plaques 13 préalablement collées sous la paroi 30, lesquelles contre-plaques 13 peuvent être elles aussi en composite verre-résine. De même, autour de la coque 2 à l'intérieur, des contre-plaques 14 sont prévues pour le vissage de profilés périphériques 15 supportant les défenses 9.Figures 7 and 8 show how the main dock accessories are attached. The members 5 are screwed through the wall 30 of the bridge 3, in counter plates 13 previously glued under the wall 30, which counter plates 13 can also be made of glass-resin composite. Similarly, around the shell 2 inside, counter-plates 14 are provided for screwing peripheral profiles 15 supporting the defenses 9.

Certains accessoires comme les pitons de levage 6 et les bittes d'amarrage nécessitent un ancrage particulièrement solide. A cet effet, on choisit leur implantation sur le pont 3 au-dessus des éléments 4, pour bénéficier de la présence de la double paroi 30-40, figure 8.Certain accessories such as lifting eyes 6 and mooring bitts require a particularly solid anchorage. For this purpose, we choose their location on the bridge 3 above the elements 4, to benefit from the presence of the double wall 30-40, FIG. 8.

Les bittes d'amarrage 7, et de la même façon les pitons de levage, sont fixés par vissage à travers la double paroi 30-40 du pont 3 et des éléments 4, dans une contre-plaque 16 préalablement collée sous la paroi 4a.The mooring bittes 7, and in the same way the lifting lugs, are fixed by screwing through the double wall 30-40 of the bridge 3 and of the elements 4, in a counterplate 16 previously glued under the wall 4a.

Pour augmenter l'efficacité du vissage, il est avantageux de prévoir, lors de la fabrication du pont 3, aux endroits d'implantation des bittes d'amarrage et des pitons de levage, des découpes dans l'âme alvéolaire du sandwich 30, pour y ménager des plaques en mortier cellulaire 17 résistant davantage aux efforts de compression.To increase the efficiency of the screwing, it is advantageous to provide, during the manufacture of the bridge 3, at the places of implantation of the mooring bittes and of the lifting studs, cut-outs in the honeycomb core of the sandwich 30, to to provide therein sheets of cellular mortar 17 more resistant to compression forces.

Les pontons conformes à l'invention sont conçus pour avoir dans leur forme la plus usuelle une longueur de l'ordre de 12 m et une largeur de l'ordre de 3 m. A titre indicatif, pour ces dimensions, il a été prévu une structure de renfort interne composée de six éléments transversaux 4 : la rigidité d'ensemble est totalement satisfaisante, ainsi que la résistance tant aux efforts locaux qu'aux .efforts latéraux de compression. En comparaison des pontons existants en acier, aux avantages relatifs à la maintenance déjà cités, s'ajoutent ceux d'une durée de vie que l'on prévoit plus longue, d'une structure simplifiée requiérant un temps de construction nettement moindre, et de l'élimination des problèmes d'électrolyse pour les navires en métal léger.The pontoons according to the invention are designed to have in their most usual form a length of the order of 12 m and a width of the order of 3 m. As an indication, for these dimensions, an internal reinforcement structure has been provided composed of six transverse elements 4: the overall rigidity is completely satisfactory, as well as the resistance both to local forces and to lateral compression forces. Compared to existing steel pontoons, with the maintenance advantages already mentioned, there are those of a longer expected service life, a simplified structure requiring significantly less construction time, and elimination of electrolysis problems for light metal vessels.
