DISPOSITIF POUR LA REALISATION DE COUVERTURES A BASE DE PANNEAUX PHOTOVOLTAÏQUES DEVICE FOR PRODUCING COVERINGS BASED ON PHOTOVOLTAIC PANELS
DOMAINE DE L'INVENTION L'invention se rapporte au domaine des couvertures d'ouvrage et autres bâtiments, et de manière générale de toitures au moyen de panneaux photovoltaïques, mettant en oeuvre une membrane assurant la fonction d'étanchéité. FIELD OF THE INVENTION The invention relates to the field of roofs of structures and other buildings, and generally to roofs by means of photovoltaic panels, implementing a membrane providing the sealing function.
10 Elle a plus spécifiquement trait aux toitures du type en question pourvues déjà d'un support continu sur lequel est destinée à être rapportée ladite membrane. It more specifically relates to roofs of the type in question already provided with a continuous support on which is intended to be reported said membrane.
ART ANTERIEUR PRIOR ART
15 Dans le cadre de mesures incitatives mises en place par les autorités, notamment françaises, en vue de favoriser le développement des sources d'énergie non fossiles, figure la notion d'intégration consistant à conférer aux panneaux photovoltaïques une fonction effective de protection et d'étanchéité au sein du bâtiment sur lequel ils sont rapportés. 15 As part of the incentives put in place by the authorities, particularly the French authorities, to promote the development of non-fossil energy sources, the notion of integration consists in giving photovoltaic panels an effective function of protection and protection. sealing within the building on which they are reported.
20 Ce faisant, de nombreuses solutions technologiques se sont développées pour, d'une part, assurer la fixation de tels panneaux photovoltaïques sur les toitures, et d'autre part, répondre au cahier des charges fixé par l'administration dans le cadre de cette notion d'intégration. In doing so, numerous technological solutions have developed to, on the one hand, ensure the fixing of such photovoltaic panels on the roofs, and on the other hand, meet the specifications set by the administration as part of this process. concept of integration.
L'une des difficultés majeures auxquelles on se heurte cependant, réside dans l'étanchéité. 25 On a par exemple proposé, dans le document DE-20 2005 015455, une solution technique consistant à assurer l'étanchéité entre les panneaux photovoltaïques et la charpente de la toiture au moyen d'une membrane recouvrant la face supérieure de plaques planes sous-jacentes. Cependant, les panneaux proprement dits sont eux-mêmes fixés au niveau de 30 profilés solidarisés par exemple à la charpente, au moyen de vis ou de clous traversant et donc perforant ladite membrane, de sorte que l'étanchéité n'est pas garantie.5 2 On a également proposé la fixation des panneaux au niveau de potelets, également rapportés sur la structure de la toiture après incision de la membrane, puis restauration de l'étanchéité en collant de manière subséquente une membrane PVC ou bitumineuse par-dessus l'incision et autour desdits potelets. Cette technique, par exemple décrite dans le document FR 2 713 687, s'avère cependant particulièrement fastidieuse et longue à mettre en oeuvre, surenchérissant de manière significative les coûts de pose de telles toitures. One of the major difficulties, however, is the sealing. DE-20 2005 015455 proposes, for example, a technical solution consisting of sealing the photovoltaic panels and the roof structure by means of a membrane covering the upper surface of sub-flat plates. underlying. However, the panels themselves are themselves fixed at the level of 30 sections secured for example to the frame, by means of screws or nails through and thus perforating said membrane, so that the seal is not guaranteed. 2 It has also been proposed to fix the panels at posts, also reported on the structure of the roof after incision of the membrane, then restore the seal by subsequently bonding a PVC or bituminous membrane over the incision and around said posts. This technique, for example described in FR 2,713,687, however, proves particularly tedious and time consuming to implement, significantly outlays the costs of laying such roofs.
De fait, le besoin s'est fait sentir d'une structure ou dispositif pour la réalisation d'une couverture à base de panneaux photovoltaïques, notamment sur des toitures plates ou à faible pente, garantissant l'étanchéité, que ladite toiture soit de type maçonné, bois, cimenté, voire même pourvue de bac aciers. In fact, the need has arisen for a structure or device for producing a roof based on photovoltaic panels, in particular on flat or low slope roofs, guaranteeing the watertightness, that said roofing is of type masonry, wood, cemented, even with steel trays.
EXPOSE DE L'INVENTION Selon l'invention, ce dispositif, dont l'étanchéité est assurée au moyen d'une membrane étanche à l'eau et pourvue de propriétés adhésives, rapportée sur une surface continue et sous-jacente par rapport à la couverture proprement dite, destiné à assurer la fixation de panneaux photovoltaïques, comprend au moins un élément profilé linéaire muni d'une embase pourvue d'une surface plane, apte à permettre le positionnement, voire la fixation desdits éléments sur la membrane, lesdits éléments profilés étant aptes à coopérer avec des moyens destinés à assurer la fixation des panneaux photovoltaïques à leur niveau. DESCRIPTION OF THE INVENTION According to the invention, this device, whose sealing is ensured by means of a waterproof membrane and provided with adhesive properties, reported on a continuous and underlying surface with respect to the cover proper, intended to ensure the fixing of photovoltaic panels, comprises at least one linear profiled element provided with a base provided with a flat surface, adapted to allow the positioning, or even the fixing of said elements on the membrane, said profiled elements being able to cooperate with means for fixing the photovoltaic panels at their level.
En d'autres termes, l'invention consiste à mettre en oeuvre des profilés linéaires de fixation des panneaux photovoltaïques, rapportés sans percement ni perforation de la membrane assurant l'étanchéité. Ce faisant, on garantit la préservation de l'intégrité de ladite membrane et corolairement l'étanchéité requise. In other words, the invention consists in implementing linear profiles for fixing photovoltaic panels, reported without piercing or perforation of the membrane ensuring the seal. In doing so, it is guaranteed the preservation of the integrity of said membrane and corollary required sealing.
Selon une caractéristique avantageuse de l'invention, la fixation des éléments profilés linéaires sur la membrane est sécurisée par l'apposition et la fixation d'un lé d'une couche ou structure adhésive, fixée de part et d'autre dudit profilé sur ladite membrane assurant l'étanchéité. According to an advantageous characteristic of the invention, the fixing of the linear profiled elements on the membrane is secured by the apposition and the fixing of a web of a layer or adhesive structure, fixed on either side of said profile on said membrane ensuring tightness.
Avantageusement, ce lé est réalisé dans une membrane de même nature que la membrane d'étanchéité, celle-ci étant typiquement de type bitumineuse. Advantageously, this web is made in a membrane of the same nature as the waterproofing membrane, the latter being typically of the bituminous type.
Selon une alternative de l'invention, le lé et la membrane peuvent être réalisés dans une 5 membrane de nature végétale. According to an alternative of the invention, the membrane and the membrane can be made in a membrane of vegetable nature.
Selon une autre caractéristique de l'invention, l'élément profilé définit une gorge ou rainure s'étendant selon la même direction que la dimension principale dudit élément profilé, et apte à recevoir les moyens proprement dits destinés à assurer la fixation des panneaux 10 photovoltaïques. Ces moyens peuvent typiquement être constitués d'un autre profilé, orienté alors sensiblement perpendiculairement par rapport à l'élément profile, de vis, vis marteau ou vis auto-taraudeuses, etc... According to another characteristic of the invention, the profiled element defines a groove or groove extending in the same direction as the main dimension of said profiled element, and adapted to receive the means proper for fixing the photovoltaic panels. . These means may typically consist of another profile, then oriented substantially perpendicularly to the profile element, screws, hammer screws or self-tapping screws, etc ...
Lesdits moyens de fixation peuvent en outre être associés à des organes aptes à optimiser 15 l'inclinaison des panneaux photovoltaïques en fonction de la localisation de la toiture ainsi recouverte. De fait, les panneaux sont susceptibles de présenter une inclinaison par rapport à l'horizontale, par exemple comprise entre 0 et 35°. Said fastening means may also be associated with organs capable of optimizing the inclination of the photovoltaic panels as a function of the location of the roof thus covered. In fact, the panels are likely to have an inclination relative to the horizontal, for example between 0 and 35 °.
BREVE DESCRIPTION DES FIGURES La manière dont l'invention peut être réalisée et les avantages qui en découlent, ressortiront mieux des exemples de réalisation qui suivent, donnés à titre indicatif et non limitatif, à l'appui des figures annexées.

FIG. 1 is a schematic representation illustrating the positioning of photovoltaic panels by means of the fixing device according to the invention. Figure 2 is a schematic representation in cross section of a profiled element implemented by the invention. FIGS. 3 and 4 illustrate the use of such a profiled element with a photovoltaic panel, respectively seen from the front and in a side view. FIG. 5 is a view similar to FIG. fixing the panel at the level of the profile. FIG. 6 is a view similar to FIG. 5, illustrating a variant of a method of fastening the panels.
EXPOSE DETAILLE DE L'INVENTION On a représenté, au sein de la figure 1, une vue partielle d'une toiture mettant en oeuvre le dispositif conforme à l'invention. Cette toiture 1 est en fait rapportée sur une surface sensiblement continue (non représentée), fixée par exemple sur des bacs aciers, sur des supports bois ou sur un support en béton. 10 Cette surface continue est revêtue d'une membrane 2, typiquement de type bitumineuse, assemblée sur cette surface sous-jacente continue, selon des procédés traditionnels (notamment collage, soudure, fixation mécanique) mis en oeuvre pour assurer l'adhérence de telles membranes bitumineuses sur une structure plane. En l'espèce, la structure sous-jacente 15 peut être de toute nature, et notamment, comme indiqué précédemment, en bois, en ciment, voire être constituée d'une pluralité de bacs acier emboités les uns dans les autres. DETAILED DESCRIPTION OF THE INVENTION FIG. 1 shows a partial view of a roof using the device according to the invention. This roof 1 is in fact reported on a substantially continuous surface (not shown), fixed for example on steel tanks, on wooden supports or on a concrete support. This continuous surface is coated with a membrane 2, typically of the bituminous type, assembled on this continuous underlying surface, according to conventional methods (especially bonding, welding, mechanical fixing) used to ensure the adhesion of such membranes. bituminous on a flat structure. In this case, the underlying structure 15 can be of any kind, and in particular, as indicated above, in wood, in cement, or even consist of a plurality of steel bins nested in each other.
Selon l'invention, sont rapportés sur la membrane 2 des éléments profilés linéaires 4, dont la fonction est d'assurer la fixation de panneaux photovoltaïques 3, par exemple par 20 l'intermédiaire de rails 7. De tels éléments profilés linéaires 4 sont par exemple illustrés sur la figure 2 en section transversale. According to the invention, linear profile elements 4, whose function is to ensure the fixing of photovoltaic panels 3, for example by means of rails 7, are reported on the membrane 2. Such linear profile elements 4 are examples shown in Figure 2 in cross section.
Ils sont typiquement réalisés en aluminium, et issus de filières. Ils présentent une embase plane 10, directement rapportée sur la membrane 2, cette dernière pouvant être 25 avantageusement réchauffée, par exemple au moyen d'un chalumeau portable ou de toute autre source de chaleur, aux fins de révéler ses propriétés adhésives et favoriser le positionnement desdits profilés selon l'orientation et la localisation souhaitées. L'embase 10 peut éventuellement être enduite d'un adhésif, afin de favoriser le positionnement desdits éléments profilés linéaires 4. 30 Les éléments profilés 4 présentent également une forme ou enveloppe supérieure 11 de forme courbe avec un grand rayon de courbure, typiquement voisin de 90 mm. Cette forme particulière de l'enveloppe supérieure 11 est destinée à favoriser la fixation dudit élément5 profilé linéaire 4 sur la membrane 2. A cet effet, on rapporte un lé 5 réalisé en une structure souple et adhésive sur l'élément profilé 4, ledit lé s'étendant de part et d'autre de ce dernier, de telle sorte à venir se fixer par collage sur la membrane 2. They are typically made of aluminum, and derived from dies. They have a flat base 10, directly attached to the membrane 2, the latter may be advantageously heated, for example by means of a portable torch or any other heat source, for the purpose of revealing its adhesive properties and promote positioning said profiles according to the desired orientation and location. The base 10 may optionally be coated with an adhesive, in order to promote the positioning of said linear profiled elements 4. The profiled elements 4 also have a shape or upper envelope 11 of curved shape with a large radius of curvature, typically close to 90 mm. This particular form of the upper casing 11 is intended to favor the attachment of said linear profiled element 4 to the membrane 2. For this purpose, there is reported a web 5 made of a flexible and adhesive structure on the profiled element 4, said web extending on both sides of the latter, so as to be fixed by gluing on the membrane 2.
Selon l'invention, il peut être envisagé d'appliquer sur l'élément profilé 4, préalablement à la mise en place du lé ou bande 5 une couche d'un agent de collage ou primaire ou promoteur d'adhérence, apte à favoriser l'adhérence du lé 5 sur ledit élément profilé, et corollairement, la fixation de ce dernier sur la toiture. According to the invention, it may be envisaged to apply to the profiled element 4, prior to the introduction of the web or strip 5, a layer of a sizing agent or primer or adhesion promoter, suitable for promoting adhesion of the lé 5 on said profiled element, and corollary, the attachment of the latter on the roof.
Avantageusement, la structure souple de solidarisation ou lé 5 est de même nature que la membrane bitumineuse 2, pour éviter tout risque d'incompatibilité des composants adhésifs respectifs. Advantageously, the flexible structure of solidarity or 5 is of the same nature as the bituminous membrane 2, to avoid any risk of incompatibility of the respective adhesive components.
Cependant, on peut également envisager de choisir pour le lé 5, voire pour la membrane 2 15 une membrane de nature végétale. However, it is also possible to choose for membrane 5 or even membrane 2, a membrane of vegetable nature.
Ainsi qu'on peut l'observer sur la figure 1, ce lé 5 n'est pas positionné sur toute la longueur de l'élément profilé 4, mais sur une partie importante dans le but évident de promouvoir l'efficacité de la fixation, et en outre pour libérer l'accès à l'éventuelle sous-structure dont 20 est muni l'élément profilé dans une variante de l'invention, aux fins de permettre la coopération des moyens de fixation des panneaux photovoltaïques 3. As can be seen in FIG. 1, this piece 5 is not positioned over the entire length of the profiled element 4, but on a large part for the obvious purpose of promoting the efficiency of the binding, and further to release access to the possible substructure which is provided with the profiled element in a variant of the invention, for the purpose of allowing the cooperation of the fixing means of the photovoltaic panels 3.
Selon une première forme de réalisation de l'invention non représentée, l'enveloppe supérieure 11 est continue et la fixation effective des organes de fixation des panneaux 25 photovoltaïques au niveau de ce profilé 4 s'effectue au moyen de vis auto-taraudantes, venant percer ladite enveloppe 11 sensiblement à l'aplomb de l'apex du profilé. According to a first embodiment of the invention not shown, the upper casing 11 is continuous and the effective fastening of the photovoltaic panel fixing members at this section 4 is effected by means of self-tapping screws, pierce said envelope 11 substantially perpendicular to the apex of the profile.
Selon une autre variante, illustrée par exemple au niveau des figures 2, 3 et 4, le profilé 4 présente une rainure ou gorge linéaire 12, s'étendant parallèlement à la dimension principale 30 dudit élément profilé. Cette rainure définit un certain nombre de cloisons 13 propres à coopérer par exemple avec une vis à tête marteau 14, également dénommée vis quart de tour, bien connue en soi et largement utilisée en raison de la commodité d'usage. Cette vis vient ainsi solidariser une équerre 15 ou une bride, venant alors directement serrer le panneau 3 sur un rail 7. According to another variant, illustrated for example in Figures 2, 3 and 4, the section 4 has a groove or linear groove 12, extending parallel to the main dimension 30 of said profiled element. This groove defines a number of partitions 13 adapted to cooperate for example with a hammerhead screw 14, also called quarter-turn screw, well known per se and widely used because of the convenience of use. This screw thus joins a bracket 15 or a flange, then directly tighten the panel 3 on a rail 7.
Alternativement, le rail 7 est solidarisé au profilé 4, également au moyen d'une vis à tête 5 marteau, le panneau 3 étant alors fixé sur le rail 7 au moyen d'une bride 16. Alternatively, the rail 7 is secured to the profile 4, also by means of a hammerhead screw, the panel 3 then being fixed on the rail 7 by means of a flange 16.
Comme indiqué en préambule, ce mode particulier de fixation ou d'intégration de panneaux photovoltaïques sur une toiture est destiné aux toits horizontaux, voire présentant une pente relativement faible, typiquement inférieure ou égale à 15° par rapport à l'horizontale. Il peut 10 cependant s'avérer souhaitable de conférer aux panneaux photovoltaïques proprement dits une inclinaison plus importante, notamment en fonction de la localisation de la toiture et de l'ensoleillement local. A cet effet, on munit les moyens de fixation précédemment décrit d'un élément intermédiaire 17, en l'espèce typiquement constituée d'une bride, venant se fixer d'une part, sur l'équerre 15, et d'autre part sur un rail 7, propre à conférer l'inclinaison 15 souhaitée, tel qu'on l'a matérialisé sur la figure 5. As indicated in the preamble, this particular method of fixing or integration of photovoltaic panels on a roof is intended for horizontal roofs, or even having a relatively low slope, typically less than or equal to 15 ° with respect to the horizontal. However, it may be desirable to give the photovoltaic panels themselves a greater inclination, in particular depending on the location of the roof and the local sunshine. For this purpose, the previously described fixing means are provided with an intermediate element 17, in this case typically consisting of a flange, being fixed on the one hand, on the bracket 15, and on the other hand on a rail 7, adapted to confer the desired inclination 15, as shown in Figure 5.
De fait, on observe une résistance à l'arrachement supérieur ou égal à 6000 Pa. In fact, a peel strength of greater than or equal to 6000 Pa is observed.
On a représenté en relation avec la figure 6 une variante de la fixation d'un panneau 20 photovoltaïque 3 sur le dispositif de l'invention, là encore, en intégrant l'inclinaison dudit panneau. FIG. 6 shows a variant of the fixing of a photovoltaic panel 3 on the device of the invention, again, by integrating the inclination of said panel.
Selon cette variante les panneaux 3 sont fixés sur un rail 20, au moyen de brides 21 De manière traditionnelle, les brides sont vissées sur le profilé de telle sorte qu'elles effectuent 25 un serrage du module contre le profilé afin d'assurer la tenue du module sans que celui-ci ne soit percé. According to this variant, the panels 3 are fixed on a rail 20, by means of flanges 21. Traditionally, the flanges are screwed onto the profile in such a way that they clamp the module against the profile in order to ensure the holding. of the module without it being pierced.
Ces rails 20 sont eux-mêmes fixés au rail 7 respectivement par une équerre 22, vissée dans ledit rail 7, et par une potence 23, sur laquelle est articulée l'autre extrémité du rail 20. La mise en oeuvre d'une telle potence 23 permet de réaliser a posteriori le changement de l'inclinaison des panneaux photovoltaïques de 13 à 17 °. Les trous de la potence 23 peuvent également être remplacés par une lumière en arc de cercle. 30 La membrane d'étanchéité 2 peut recevoir des granulés, de type schiste ou paillettes d'ardoise, ce qui permet de s'affranchir de l'emploi de membranes de type nécessitant une protection contre les UV. These rails 20 are themselves fixed to the rail 7 respectively by a bracket 22, screwed into said rail 7, and a bracket 23, on which is articulated the other end of the rail 20. The implementation of such a bracket 23 makes it possible to carry out a posteriori the change of the inclination of the photovoltaic panels from 13 to 17 °. The holes of the stem 23 may also be replaced by an arcuate light. The sealing membrane 2 can receive granules, of the shale or slate flake type, which makes it possible to dispense with the use of membranes of the type requiring protection against UV radiation.
On conçoit tout l'intérêt de la présente invention, tout d'abord de par la préservation systématique de l'intégrité de la membrane 2 assurant l'étanchéité effective. On ne se heurte plus de fait à un quelconque problème de fuite né notamment de la perforation de ladite membrane. We understand the whole point of the present invention, first of all by the systematic preservation of the integrity of the membrane 2 ensuring effective sealing. No one actually runs into any leakage problem born in particular the perforation of said membrane.
En outre, on conçoit la facilité de pose de tels panneaux photovoltaïques en raison de la mise en oeuvre de profilés simples à positionner et à fixer, générant ainsi un gain de temps significatif et réduisant d'autant les frais d'une telle installation. In addition, the ease of installation of such photovoltaic panels is conceivable because of the implementation of simple profiles to be positioned and fixed, thus saving significant time and reducing the costs of such an installation.
Au surplus, l'invention permet de s'affranchir de la mise en oeuvre de ballast ou dispositif équivalent. In addition, the invention eliminates the implementation of ballast or equivalent device.
Enfin, en raison des moyens de fixation simples à mettre en oeuvre, on peut procéder à de nombreux montages et démontages des panneaux photovoltaïques, en vue de pourvoir à leur remplacement ou d'assurer la maintenance y relative.20 Finally, because of the simple fastening means to be implemented, it is possible to proceed with numerous assemblies and disassembly of the photovoltaic panels, with a view to their replacement or to ensure the relative maintenance thereof.
