Abstract

The invention relates to a high-strength composite panel intended for the construction of rigid structures. It has a profile comprising a ribbed plate 1 solidly placed between two plates 2 and 3 so as to form a rigid "sandwich" panel obtained by assembling or directly by extrusion. Among the most useful applications of the invention, mention may be made of floating decking for inflatable craft, the aeronautical field, structures for boats, vehicles and caravans, the building industry and the furniture industry.

Description

Panneau composite de haute résistance
Le présente invention concerne un panneau composite de haute résistance destiné à la construction de structures légères et rigides.High resistance composite panel
The present invention relates to a high-resistance composite panel intended for the construction of light and rigid structures.

On connait déjà pour cet usage, des panneaux constitués par une âme en nids d'abeille et dont les deux faces sont revetues par collage avec des feuilles en aluminium ou en stratifié de tissu de verre ou de carbone. We already know for this use, panels formed by a honeycomb core and whose two sides are coated by gluing with aluminum sheets or laminate of glass or carbon fabric.

Pour d'autres usages, on connait un carton possédant des cannelures en profil arrondi, régulièrement espacées, entrecollXes entre deux feuilles de papier fort. For other uses, we know of a cardboard box having grooves in rounded profile, regularly spaced, interspersed between two sheets of strong paper.

Toujours pour d'autres usages, on connait des planchers creux avec ou sans hourdis et réalises en béton armé. Still for other uses, we know of hollow floors with or without slabs and made of reinforced concrete.

Le but de l'invention est de proposer un nouveau type de panneau dont les caracteristiques en font recommander l'adoption pour la construction des structures rigides du fait qu'il peut supporter un meilleur moment d'inertie à moindre prix. The object of the invention is to propose a new type of panel whose characteristics make it recommend the adoption for the construction of rigid structures because it can withstand a better moment of inertia at a lower price.

En première variante, le profil du panneau est obtenu directement par extrusion d'une matière rendue malléable, ce profil Étant identique pour ses caractéristiques à celui de la deuxième variante qui sera développée ci-aprés. In the first variant, the profile of the panel is obtained directly by extrusion of a material made malleable, this profile being identical for its characteristics to that of the second variant which will be developed below.

En deuxième variante, le panneau est composé d'une âme présentant des nervures paralléles et dont les deux faces sont revêtus de deux plaques de même ou différente matière. In a second variant, the panel is composed of a core having parallel ribs and the two faces of which are coated with two plates of the same or different material.

Ces deux variantes ne se différencient que par le mode de fabrication. On obtient dans l'un ou l'autre cas, un panneau plat rigide dont le poids est faible et le prix mordoré. Le panneau, objet de l'invention, se coupe et s'usine avec l'outillage d'atelier et autorise des formes complu quées avec ustructure rigide et robuste tout en présentant une bonne stabilité dimensionnelle. These two variants differ only by the method of manufacture. In one or the other case, a rigid flat panel is obtained whose weight is low and the price bronze. The panel, object of the invention, is cut and machined with the workshop tools and allows complicated shapes with rigid and robust structure while having good dimensional stability.

Ces deux variantes se décomposent en un profil formant dans un sens des nervures ayant un pas et une hauteur appropri ées aux efforts et deux plaques de nature et épaisseur adaptées, ces trois éléments formant une structure nsandwiche. Dans le sens perpendiculaire, ces nervures et ces deux plaques forment un ensemble de caissons juxtaposés. These two variants break down into a profile forming in one direction ribs having a pitch and a height suitable for the forces and two plates of suitable nature and thickness, these three elements forming a nsandwiche structure. In the perpendicular direction, these ribs and these two plates form a set of juxtaposed boxes.

En première variante, le panneau étant obtenu par extrusion, donne un profil à section droite constante qui ne présente aucun problème de liaison entre les trois composants. In a first variant, the panel being obtained by extrusion, gives a profile with constant cross section which presents no problem of connection between the three components.

Pour la deuxième variante, le mode d'assemblage revêt une importance considérable car tout glissement entre les surfaces en contact occasionnerait une possibilité de translation géométrique des structures composées. A cette fin, on utilisera des moyens de soudure, de collage ou d'assemblage. For the second variant, the method of assembly is of considerable importance since any sliding between the surfaces in contact would cause a possibility of geometric translation of the composite structures. To this end, means of welding, bonding or assembly will be used.

Lt invention sera mieux comprise et les avantages appa raîtrontau cours de la description donnée ci-dessous à titre d'exemple. The invention will be better understood and the advantages will become apparent from the description given below by way of example.

Il est bien entendu que la description et les dessins ne sont donnés qu'à titre indicatif et non limitatif. It is understood that the description and the drawings are given for information only and are not limiting.

Il sera fait référence aux dessins annexés, dans lesquels
- la figure 1 est un éclaté d'une première réalisation d'un panneau assemblé conforme à l'invention;
- la figure 2 est une coupe longitudinale du panneau précité;
- la figure 3 est une coupe transversale du panneau précité.Reference will be made to the accompanying drawings, in which
- Figure 1 is an exploded view of a first embodiment of an assembled panel according to the invention;
- Figure 2 is a longitudinal section of the aforementioned panel;
- Figure 3 is a cross section of the aforementioned panel.

Il s'agit, dans l'exemple donné, d'un plancher flottant en alliages d'aluminium destiné à un bateau pneumatique. In the example given, this is a floating floor made of aluminum alloys intended for an inflatable boat.

Il est constitué d'une tôle 1 présentant des nervures trapézoidales inversées régulièrement, placée entre deux plaques planes 2 et 3, l'assemblage étant réalisé au pourtour et aux surfaces de contact 4 par un adhésif 5 et 6 ayant une forte adhérence et des résistances mécaniques élevées. It consists of a sheet 1 having regularly inverted trapezoidal ribs, placed between two flat plates 2 and 3, the assembly being carried out at the periphery and at the contact surfaces 4 by an adhesive 5 and 6 having a strong adhesion and resistances high mechanical.

Le revêtement supérieur du plancher 7 est enduit de billes de verre collées afin d'empêcheur le dérapage des passagers sur le bateau. The upper covering of the floor 7 is coated with glued glass beads in order to prevent the skidding of the passengers on the boat.

Tel qu'il est représenté, le plancher esr rendu absolument étanche par masticage, pliage 8 des tôles 2 et 3 et insertion d'un profilé 9 adapté à l'épaisseur du plancher. As shown, the floor is made absolutely waterproof by puttying, folding 8 of the sheets 2 and 3 and insertion of a profile 9 adapted to the thickness of the floor.

La densité suffisamment faible obtenue doit assurer une parfaite flottabilité du panneau, Si nécessaire. The sufficiently low density obtained must ensure perfect buoyancy of the panel, if necessary.

Le dispositif, objet de l'invention, constitue un matériau idéal pour les pontages, cloisons, panneaux, mobilier et autres usages. The device, object of the invention, constitutes an ideal material for decking, partitions, panels, furniture and other uses.

Des applications particulièrement intéressantes sont faites dans le domaine aéronautique, les bateaux, les véhicules, les caravanes, le batiment et le mobilier.  Particularly interesting applications are made in the aeronautical field, boats, vehicles, caravans, buildings and furniture.
