Description

La présente invention a pour objet un dispositif de contenant en matièreThe subject of the present invention is a device for containing

thermoplastique pour le stockage et/ou le transfert d'un fluide, ainsi que le procédé de fabrication dudit dispositif.  thermoplastic for the storage and / or transfer of a fluid, as well as the manufacturing method of said device.

La présente invention concerne plus particulièrement le domaine de la chaudronnerie plastique et notamment la fabrication de pièces telles que des cuves ou analogues, des caissons ou des gaines, pour le stockage et le transport de fluides tels que des liquides ou des gaz.  The present invention relates more particularly to the field of plastic boilermaking and in particular the manufacture of parts such as tanks or the like, boxes or sheaths, for the storage and transport of fluids such as liquids or gases.

Les pièces précitées sont traditionnellement fabriquées par assemblage et soudages d'éléments en matière thermoplastique telle que, non limitativement, du polyéthylène et du polypropylène. Ces éléments se présentent essentiellement sous la forme de panneaux, plaques, bandes et cordons, découpés et soudés pour obtenir la pièce désirée.  The aforementioned parts are traditionally manufactured by assembling and welding thermoplastic elements such as, but not limited to, polyethylene and polypropylene. These elements are essentially in the form of panels, plates, strips and cords, cut and welded to obtain the desired part.

Plus les pièces sont de grandes dimensions, telles que des cuves de stockage par exemple, plus elles sont longues à fabriquer du fait notamment de la nécessité de multiplier les renforts pour pallier le manque de rigidité de la matière utilisée.  The larger the parts are, such as storage tanks for example, the longer they are to manufacture due in particular to the need to multiply the reinforcements to overcome the lack of rigidity of the material used.

Pour certaines activités, où sont utilisés des fluides qui peuvent être nocifs, il est indispensable, voire obligatoire, de prévoir des moyens de rétention, ce qui est obtenu par le doublage des parois. En pratique, après réalisation d'une pièce comprenant une enveloppe renforcée extérieurement par des nervures, on soude sur lesdites nervures une seconde enveloppe. La fabrication de telles pièces présente donc l'inconvénient d'être coûteuse en main d'oeuvre.  For some activities, where fluids are used which can be harmful, it is essential, even mandatory, to provide means of retention, which is obtained by doubling the walls. In practice, after making a part comprising a casing reinforced externally by ribs, a second casing is welded to said ribs. The manufacture of such parts therefore has the disadvantage of being expensive in manpower.

La présente invention a pour but de proposer un dispositif de contenant en matière thermoplastique pour le stockage et/ou le transfert d'un fluide et son procédé de fabrication, permettant de remédier à cet inconvénient.  The present invention aims to provide a thermoplastic container device for the storage and / or transfer of a fluid and its manufacturing process, to overcome this disadvantage.

Le dispositif de contenant en matière thermoplastique pour le stockage et/ou le transfert d'un fluide, selon l'invention est du type venant de l'assemblage et le soudage d'éléments en matière thermoplastique, et il se caractérise en ce que ses parois viennent de l'assemblage et le soudage de panneaux en matière thermoplastique comprenant chacun deux plaques planes parallèles, entretoisées au moyen d'une âme qui leur est solidarisée par soudage, constituée d'au moins une plaque conformée pour présenter une succession de cannelures, ou analogues, parallèles.  The thermoplastic container device for storing and / or transferring a fluid according to the invention is of the type coming from the assembly and welding of thermoplastic elements, and it is characterized in that its walls come from the assembly and welding of thermoplastic panels each comprising two parallel flat plates, braced by means of a core which is secured to them by welding, consisting of at least one plate shaped to present a succession of grooves, or the like, parallel.

Les panneaux, dont est essentiellement constitué un dispositif de contenant selon l'invention, présentent originellement une très grande rigidité, en sorte qu'il n'est pas nécessaire, après assemblage, de disposer des renforts supplémentaires que ce soit aussi bien du côté interne que du côté externe du dispositif contenant.  The panels, which essentially consists of a container device according to the invention originally have a very high rigidity, so that it is not necessary, after assembly, to have additional reinforcements either on the internal side as well. only on the external side of the device containing.

Un dispositif de contenant selon l'invention, outre sa rigidité, présente de nombreux avantages. Les deux plaques planes des panneaux permettent après assemblage d'obtenir sans opérations supplémentaires une enveloppe double.  A container device according to the invention, besides its rigidity, has many advantages. The two flat plates of the panels allow after assembly to obtain without additional operations a double envelope.

Par ailleurs, les cannelures donnent au panneau une forme alvéolaire qui permet de réaliser une certaine isolation, que ce soit au travers de l'air emprisonné ou d'un matériau isolant disposé dans les alvéoles.  Furthermore, the flutes give the panel a honeycomb shape that allows for some insulation, either through trapped air or an insulating material disposed in the cells.

Selon une caractéristique additionnelle du dispositif selon l'invention, la plaque qui constitue l'âme du panneau est conformée en forme d'accordéon.  According to an additional feature of the device according to the invention, the plate which constitutes the core of the panel is shaped accordion-shaped.

Selon un mode de réalisation particulier du dispositif selon l'invention, la plaque conformée qui constitue l'âme du panneau se présente sous la forme d'une succession de bandes faisant entre elles deux à deux un angle, dont une sur deux, successives, est soudée à la face interne d'une des plaques planes, et en alternance sur chacune de ces dernières.  According to a particular embodiment of the device according to the invention, the shaped plate which constitutes the core of the panel is in the form of a succession of strips forming between them two by two an angle, of which one out of two, successive, is welded to the inner face of one of the flat plates, and alternately on each of these.

Selon une caractéristique additionnelle du mode de réalisation particulier du dispositif selon l'invention, les bandes font entre-elles un angle droit.  According to an additional characteristic of the particular embodiment of the device according to the invention, the strips form between them a right angle.

La présente demande a également pour objet un procédé de fabrication d'un dispositif de contenant en matière thermoplastique pour le stockage et/ou le transfert d'un fluide, qui se caractérise en ce qu'il consiste d'une part à découper des panneaux en matière thermoplastique comprenant deux plaques planes parallèles, entretoisées au moyen d'une âme, solidarisée par soudage, constituée d'au moins une plaque conformée pour présenter une succession de cannelures, ou analogues, parallèles; d'autre part à assembler lesdits panneaux, puis à les souder entre eux.  The present application also relates to a method of manufacturing a thermoplastic container device for storing and / or transferring a fluid, which is characterized in that it consists firstly in cutting panels thermoplastic material comprising two parallel flat plates, bridged by means of a web, joined by welding, consisting of at least one plate shaped to present a succession of grooves, or the like, parallel; on the other hand to assemble said panels and then to weld them together.
