Abstract
Description
La présente invention a pour objet un procédé de fabrication de panneaux destinés plus particulièrement à la réalisation de piscines. The present invention relates to a method of manufacturing panels intended more particularly for the production of swimming pools.
Actuellement on construit couramment la structure rigide d' une piscine à partir d'un certain nombre d'éléments que l'on assemble entre eux. Ces éléments se composent généralement de parois en matière plastique, sur lesquelles sont fixés des éléments de renfort régulièrement espacés, et qui sont recouvertes sur leur face intérieure d'un film de matière plastique, désigné généralement par sa dénomination anglaise "LINER", pour assurer l'étanchéité. Currently the rigid structure of a swimming pool is commonly constructed from a certain number of elements which are assembled together. These elements generally consist of plastic walls, on which are regularly spaced reinforcing elements, and which are covered on their inner face with a plastic film, generally designated by its English name "LINER", to ensure sealing.
La présente invention a pour objet un procédé de fabrication de panneaux de grande longueur qui ne nécessite pas la pose d'un film de matière plastique et qui offre un coût de fabrication et des délais de mise en oeuvre inférieurs à ceux des systèmes conventionnels. The subject of the present invention is a process for manufacturing very long panels which does not require the laying of a plastic film and which offers a lower manufacturing cost and shorter lead times than conventional systems.
Le procédé de fabrication de panneaux selon l'invention consiste à partir d'au moins un profilé de matière composite dont la longueur est sensiblement identique au panneau que l'on désire fabriquer, à introduire une extrémité dudit profilé dans une presse d'injection où l'on injecte une matière plastique de manière à former autour dudit profilé un premier panneau, solidarisé à celuici par la fusion de ladite matière plastique, puis à déplacer ledit premier panneau, dont un coté latéral sera soudé par fusion avec le coté latéral adjacent d'un deuxième panneau réalisé de manière identique avec la presse d'injection, puis à déplacer ledit profilé et les deux panneaux de manière à réaliser un troisième panneau dont un coté latéral sera soudé par fusion au coté latéral libre du deuxième panneau, et ainsi de suite jusqu'à la réalisation du dernier panneau. The method of manufacturing panels according to the invention consists in using at least one profile of composite material, the length of which is substantially identical to the panel which it is desired to manufacture, in introducing an end of said profile into an injection press where a plastic material is injected so as to form around said profile a first panel, joined thereto by the fusion of said plastic material, then to move said first panel, one side of which will be welded by fusion with the adjacent side of d a second panel produced identically with the injection press, then to move said profile and the two panels so as to produce a third panel, one side of which will be welded by fusion to the free side of the second panel, and thus until the last panel is completed.
Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, étant entendu que cette description ne présente aucun caractère limitatif vis à vis de l'invention. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which relates to the appended drawing, it being understood that this description has no limiting character with respect to the invention.
Dans le dessin annexé les figures representent des vues en perspective schématiques d'un panneau en cours de réalisation selon le procédé de l'invention. In the accompanying drawing, the figures represent schematic perspective views of a panel being produced according to the method of the invention.
Sur ces figures on peut voir un outillage mécanique de moulage comprenant deux coques rectangulaires 2 et 2' disposées parallèlement de part et d'autre de deux profilés 1 et 1' parallèles entre eux et deux barrettes verticales 3 et 3' dont une barrette 3' est enfilée sur les deux profilés l et 1' par deux orifices 30 et est apte à se déplacer librement le long desdits profilés. In these figures we can see a mechanical molding tool comprising two rectangular shells 2 and 2 'arranged parallel on either side of two sections 1 and 1' parallel to each other and two vertical bars 3 and 3 'including a bar 3' is threaded on the two sections 1 and 1 ′ by two orifices 30 and is able to move freely along said sections.
Si on se réfère d'abord à la figure la on peut voir que les extrémités 10 et 10' des profilés 1 et 1' sont amenées entre les deux coques 2 et 2' en vue de la réalisation d'un premier panneau dont la longueur est déterminée par le positionnement de la barrette 3' le long des deux profilés 1 et 1', les barrettes 3 et 3' servant à fermer les cotés du moule formé par les deux coques 2 et 2'. If we refer first to Figure la we can see that the ends 10 and 10 'of the profiles 1 and 1' are brought between the two shells 2 and 2 'for the production of a first panel whose length is determined by the positioning of the bar 3 'along the two sections 1 and 1', the bars 3 and 3 'serving to close the sides of the mold formed by the two shells 2 and 2'.
Si on se réfère ensuite à la figure lb on peut voir que les deux coques rectangulaires 2 et 2' ont été appliquées l'une contre l'autre par leurs bords 20 et 20', en sorte que leurs faces internes viennent au contact des faces latérales ll et ll' des profilés 1 et l'. Les extrémités 22 et 22' des deux coques 2 et 2' ainsi rapprochées sont fermées par les deux barrettes verticales 3 et 3' de manière à former un moule où l'on puisse y injecter un produit thermoplastique en vue de la réalisation d'un premier panneau. Les moyens mécaniques permettant d'obtenir ce résultat, ainsi que les conduits d'amenage du produit thermoplastique, injecté par une presse à injection dans ledit moule, sont connus de l'homme du métier et ne sont donc pas représentés sur la figure. If we then refer to Figure 1b we can see that the two rectangular shells 2 and 2 'have been applied against each other by their edges 20 and 20', so that their internal faces come into contact with the faces lateral ll and ll 'of profiles 1 and l'. The ends 22 and 22 ′ of the two shells 2 and 2 ′ thus brought together are closed by the two vertical bars 3 and 3 ′ so as to form a mold into which a thermoplastic product can be injected therein in order to produce a first panel. The mechanical means making it possible to obtain this result, as well as the conduits for supplying the thermoplastic product, injected by an injection press into said mold, are known to those skilled in the art and are therefore not shown in the figure.
Si on se réfère maintenant à la figure lc on peut voir qu'après l'injection du produit thermoplastique et après son refroidissement on a dans un premier temps, après ouverture des deux coques 2 et 2', obtenu un premier panneau 4 lié par fusion avec la matière plastique constituant les profilés 1 et 1', puis dans un deuxième temps déplacé longitudinalement, d'une distance sensiblement égale à la longueur du panneau 4, les deux profilés 1 et 1' et le panneau 74 solidarisé audits profilés, puis escamoté la barrette 3 par exemple par des moyens hydrauliques, non représentés, et refermé les deux coques 2 et 2' sur les profilés 1 et 1' afin de réaliser un deuxième panneau, le coté latéral 22' du moule formé par les deux coques 2 et 2' ainsi rapprochées n'étant plus ferme par la barrette 3 comme dans la réalisation du premier panneau 4 mais par le coté latéral 40 dudit panneau 4, ce qui permet de solidariser celui-ci par fusion au coté latéral 40' du deuxième panneau 4', comme on peut le voir sur la figure ld. If we now refer to FIG. 1c, we can see that after the injection of the thermoplastic product and after its cooling, we firstly, after opening the two shells 2 and 2 ', obtained a first panel 4 bonded by fusion with the plastic material constituting the profiles 1 and 1 ′, then in a second time displaced longitudinally, by a distance substantially equal to the length of the panel 4, the two profiles 1 and 1 ′ and the panel 74 secured to said profiles, then retracted the bar 3 for example by hydraulic means, not shown, and closed the two shells 2 and 2 'on the sections 1 and 1' in order to produce a second panel, the lateral side 22 'of the mold formed by the two shells 2 and 2 'thus close together no longer firm by the bar 3 as in the production of the first panel 4 but by the lateral side 40 of said panel 4, which makes it possible to secure the latter by fusion to the lateral side 40' of the second Panel I 4 ', as shown in Figure ld.
Sur la figure ld on voit que le procédé selon l'invention permet la réalisation d'un panneaux de grande longueur 5 constitué par l'assemblage par fusion de plusieurs panneau 4 et 4'. On voit en effet sur cette figure la phase se situant juste avant la réalisation d'un troisième panneau, après écartement des deux coques 2 et 2' et déplacement longitudinal des profilés 1 et 1' d'une longueur sensiblement égale à la longueur d'un panneau 4 ou 4'. In FIG. 1d it can be seen that the method according to the invention allows the production of a very long panel 5 constituted by the assembly by fusion of several panels 4 and 4 '. We can see in this figure the phase located just before the realization of a third panel, after separation of the two shells 2 and 2 'and longitudinal displacement of the profiles 1 and 1' of a length substantially equal to the length of a 4 or 4 'panel.
La solidarisation entre eux des panneaux 4 et 4' et des panneaux suivants, non représentés, confère à l'ensemble une très bonne étanchéité, rendant inutile la pose d'un film de matière plastique sur les panneaux de grande longueur 5 destinés à la réalisation d'une piscine. The joining together of the panels 4 and 4 'and the following panels, not shown, gives the assembly a very good seal, making it unnecessary to lay a plastic film on the very long panels 5 intended for the production a swimming pool.
