Abstract

The multi-section assembly provides both the function of fastening panels (5), namely solar panels, inserted in roofing and the function of sealing the roofing and its panels. It mainly comprises a lower section (1), fastened to the horizontal purlins (40) of the roof truss structure, a central section (2), a thermal bridge break, between its lower portion (21) and its upper portion (22), and an upper section (3), having lateral gutters (32) and (33) and an internal cavity (34) receiving an inter-section gutter (10), in the case where two assemblies are butted together. The assembly makes it possible to collect the water flowing between the panels and especially via inter-module metal sheets (9), in three-layer roofing, namely solar panels, cooling air layer and insulation panels. In addition, an air recovery system (42 - 45) can be easily integrated thereinto.

ENSEMBLE DE PROFILES POUR LA FIXATION ETANCHE DE PANNEAUX SUR UNE CHARPENTE DE TOIT ASSEMBLY OF PROFILES FOR THE SEALING OF PANELS ON A ROOF FRAME
DESCRIPTIONDESCRIPTION
DOMAINE DE L'INVENTIONFIELD OF THE INVENTION
L' invention concerne le domaine des habitations et bâtiments et, tout particulièrement, des bâtiments devant recevoir des panneaux solaires sur leur toiture. L'invention s'applique, entre autres, aux bâtiments industriels dont l'ossature de la toiture possède des pannes horizontales.The invention relates to the field of houses and buildings and, in particular, buildings to receive solar panels on their roof. The invention applies, inter alia, to industrial buildings whose skeleton roof has horizontal failures.
ART ANTERIEUR ET PROBLEME POSEPRIOR ART AND PROBLEM POSE
II a déjà été envisagé d'installer des panneaux solaires sur des toitures de bâtiments, tels que des bâtiments industriels, des hangars, etc. dont la charpente de la toiture est constituée, entre autres, de pannes horizontales et d'éléments de couverture. En plus des bâtiments neufs, il a été envisagé de placer les panneaux solaires sur une toiture. Il est d'usage, selon la réglementation en vigueur en France, d'enlever les parties constitutives fonctionnelles de la toiture assurant l'étanchéité de cette dernière, c'est-à-dire les tuiles ou tôles constituant la protection proprement dite du bâtiment aux endroits où l'on veut placer des panneaux. A ces endroits, on ne laisse que la structure porteuse, en particulier les pannes horizontales.It has already been envisaged to install solar panels on roofs of buildings, such as industrial buildings, sheds, etc. whose roof structure consists of, among other things, horizontal failures and roofing elements. In addition to new buildings, it has been envisaged to place solar panels on a roof. It is customary, according to the regulations in force in France, to remove the functional components of the roof ensuring the watertightness of the latter, that is to say the tiles or sheets constituting the actual protection of the building where you want to place signs. In these places, only the load-bearing structure is left, especially the horizontal ones.
On se place dans le cas où la structure porteuse de la toiture est une charpente métallique constituée, entre autres de pannes horizontales portant les éléments de couverture. Ces pannes sont, dans la plupart des cas, des profilés en acier en forme de I pour les profilés à chaud ou en forme de oméga pour les profilés obtenus par pliage à froid ou encore des pannes en bois.We place ourselves in the case where the supporting structure of the roof is a metal frame consisting of, among other things, horizontal faults carrying the covering elements. These failures are, in most cases, I-shaped steel profiles for hot or omega-shaped profiles for cold-rolled sections or wooden purlins.
On connaît déjà des profilés d'adaptation destinés à être placés perpendiculairement sur les pannes, de manière analogues à des chevrons, et ayant une forme adaptée à la réception, de part et d'autre de chaque élément, d'un panneau à positionner, supporter et à maintenir. De tels rails supports sont donc fixés sur les pannes. Un tel montage de deux panneaux adjacents est surmonté d'une languette d' étanchéité appelée « parclose ».Adaptation profiles intended to be placed perpendicularly on the purlins are already known, similarly to chevrons, and having a shape adapted to receiving, on either side of each element, a panel to be positioned, endure and maintain. Such support rails are therefore fixed on the purlins. Such an assembly of two adjacent panels is surmounted by a sealing tab called "clapboard".
Différentes formes ont été envisagées pour assurer la résistance mécanique des rails supports de panneaux, leur fonction d' étanchéité, les panneaux devant également assurer la fonction de toiture puisqu' étant intégrés dans le toit à la place des tuiles ou d'éléments de toiture classiques.Various forms have been envisaged to ensure the mechanical strength of the panel support rails, their sealing function, the panels also having to perform the roof function since they are integrated in the roof instead of tiles or conventional roof elements. .
Le souci du déposant est d'améliorer le côté étanchéité et la pérennité de tels systèmes de fixation de panneaux solaires sur des toitures comportant des pannes horizontales.The concern of the applicant is to improve the sealing side and durability of such solar panel fixing systems on roofs with horizontal failures.
RESUME DE L'INVENTIONSUMMARY OF THE INVENTION
Dans ce but, l'objet principal de l'invention est un ensemble de profilés pour la fixation étanche de panneaux sur la charpente d'un toit comprenant des pannes horizontales, l'ensemble de profilés devant être fixés perpendiculairement aux pannes, et comprenant : une partie inférieure destinée à la fixation de l'ensemble de profilés sur les pannes, et - une partie supérieure destinée à recevoir un panneau sur chacun de ses côtés, l'ensemble constitué des bords des panneaux, de la partie supérieure de l'ensemble de profilés étant surmonté d'une « parclose ». Selon l'invention : la partie inférieure est un profilé inférieur ; la partie supérieure est un profilé supérieur possédant des moyens de gouttières pour réceptionner l'eau s' écoulant éventuellement entre les panneaux, et un profilé central est prévu pour s'emboîter dans le profilé inférieur et sur lequel est fixé le profilé supérieur. Dans la réalisation préférentielle de l'invention, l'emboîtement du profilé central dans le profilé inférieur se fait dans une pince du profilé inférieur .For this purpose, the main object of the invention is a set of profiles for the waterproof fastening of panels on the roof structure including horizontal failures, the set of profiles to be fixed perpendicular to the purlins, and comprising: a lower part intended for fixing the set of profiles on the purlins, and - an upper part intended to receive a panel on each of its sides, the assembly consisting of the edges panels, the upper part of the set of profiles being surmounted by a "bead". According to the invention: the lower part is a lower profile; the upper part is an upper profile having gutter means for receiving water possibly flowing between the panels, and a central section is provided to fit into the lower profile and on which is fixed the upper profile. In the preferred embodiment of the invention, the interlocking of the central section in the lower section is in a clamp of the lower profile.
De préférence, l'ensemble de profilés comporte des moyens d'espacement de manière à laisser un espace pour permettre une circulation d'air entre des panneaux isolants et les panneaux vers une sortie située vers le haut du toit.Preferably, the set of profiles comprises spacing means so as to leave a space to allow air flow between insulating panels and the panels to an outlet located up the roof.
Cela permet avantageusement de refroidir les panneaux solaires et ainsi d'augmenter leur rendement. La perte de rendement d'un module photovoltaïque étant, en moyenne, de 0,5% par degré supplémentaire au-dessus de la température nominale de fonctionnement. L'air extérieur entre par la partie basse du toit et sort par la partie haute de celui-ci après avoir absorbé la chaleur provenant des panneaux solaires .This advantageously makes it possible to cool the solar panels and thus to increase their efficiency. The loss of performance of a module photovoltaic energy being, on average, 0.5% per additional degree above the nominal operating temperature. The outside air enters through the lower part of the roof and exits through the upper part of the roof after absorbing heat from the solar panels.
De préférence, la sortie comporte des moyens de récupération d'air.Preferably, the outlet comprises means for recovering air.
De préférence, au moins un panneau isolant positionné à proximité de la sortie est traversé par des moyens de récupération d'air comportant au moins une extrémité d'un conduit débouchante dans la sortie, le conduit étant relié à un système d'extraction d'air pour forcer la circulation d'air. Le flux d'air est ainsi augmenté et le refroidissement des panneaux est amélioré. Les conduits sont reliés à un tube d'extraction lui-même relié à un extracteur d'air, de préférence motorisé. Des capteurs de température sont installés dans le bâtiment comportant la présente invention. Si l'air extrait du toit a une température plus élevée que celui contenu dans le bâtiment, l'air extrait est utilisé pour réchauffer le bâtiment, par exemple pendant la période hivernale. En revanche si l'air extrait a une température plus chaude, par exemple pendant la période estivale, celui-ci est éjecté vers l'extérieur du bâtiment .Preferably, at least one insulating panel positioned near the outlet is traversed by air recovery means comprising at least one end of a duct opening into the outlet, the duct being connected to an extraction system. air to force air circulation. The air flow is thus increased and the cooling of the panels is improved. The ducts are connected to an extraction tube itself connected to an air extractor, preferably motorized. Temperature sensors are installed in the building comprising the present invention. If the air extracted from the roof has a higher temperature than that contained in the building, the extracted air is used to heat the building, for example during the winter period. On the other hand, if the extracted air has a warmer temperature, for example during the summer period, it is ejected towards the outside of the building.
De préférence, des capteurs de température sont disposés au niveau des panneaux et sont reliés à un système de régulation du débit d'air de manière à maintenir la température de fonctionnement des panneaux dans une plage nominale.Preferably, temperature sensors are arranged at the level of the panels and are connected to an air flow control system so as to maintain the operating temperature of the panels within a nominal range.
Ceci permet d'avoir un asservissement du débit d'air et ainsi d'optimiser le fonctionnement des panneaux solaires.This allows to have a servo of the air flow and thus to optimize the operation of the solar panels.
De préférence, l'ensembe de profilés comporte une rupture de pont thermique de manière à limiter la transmission de chaleur entre la partie supérieure et la partie inférieure. Une rupture de pont thermique permet de limiter la transmission de chaleur entre la partie inférieure et la partie supérieure.Preferably, the set of profiles has a thermal break in order to limit the heat transfer between the upper part and the lower part. A thermal break allows to limit the heat transfer between the lower part and the upper part.

De préférence, le profilé central possède des pattes faisant saillie latéralement et permettant de compresser des panneaux isolants en coopération avec des pointes sur des extrémités du profilé inférieur.Preferably, the central section has laterally projecting lugs and for compressing insulating panels in cooperation with points on ends of the lower profile.
De façon préférentielle, le profilé central a, à de chacun de ses côtés, un bord incliné vers le bas faisant saillie de part et d'autre pour recevoir chacun une partie inclinée de fixation du profilé supérieur, dans le but de les solidariser avec des vis "auto-foreuses" .Preferably, the central section has, at each of its sides, a downwardly inclined edge protruding on either side to each receive an inclined portion for fixing the upper profile, in order to secure them with self-drilling screws.
Dans une réalisation préférentielle de l'invention, on prévoit des moyens de gouttière pour le profilé supérieur constitués de, entre autres, une gouttière latérale inférieure dans le prolongement de la partie inclinée de fixation.In a preferred embodiment of the invention, gutter means are provided for the upper profile consisting of, inter alia, a lower side gutter in the extension of the inclined fixing part.
Dans sa réalisation préférentielle, le profilé supérieur possède une partie centrale creuse pour recevoir une gouttière "interprofilés" qui pénètre dans la partie centrale creuse de chacun des deux profilés supérieurs adjacents.In its preferred embodiment, the upper profile has a hollow central portion to receive an "interprofiled" gutter which penetrates into the hollow central portion of each of the two adjacent upper sections.
De préférence, l'ensemble de profilés comporte au moins une tôle intermédiaire ayant un premier appui sur une première surface d'un premier profilé et un second appui sur une seconde surface d'un second profilé, la première surface d'appui étant plus haute que la seconde surface d'appui de manière à donner une inclinaison à ladite au moins tôle intermédiaire, elle-même étant placée entre les panneaux perpendiculairement à l'ensemble de profilés et parallèlement aux pannes horizontales pour récupérer l'eau entre les panneaux dans leur jonction horizontale .

DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION
En référence à la figure 1, l'ensemble de profilés est monté sur une toiture de charpente métallique constituée d' IPNs 38 faisant office de chevrons et portant des pannes horizontales 40 placées horizontalement. Sur ces dernières, sont fixés, à intervalle déterminé en fonction de la largeur de panneaux solaires 5 à installer, des ensembles de profilés 100 qui ont pour fonction de supporter et maintenir ces panneaux solaires 5. Cette construction se complète de tôles intermodules 9 placées parallèlement aux pannes 40 sur les bords inférieurs et supérieurs des panneaux 5. Cette toiture peut se compléter de panneaux isolants 7 placés en dessous des panneaux 5 et au-dessus des pannes horizontales 40. En référence à la figure 2, on retrouve la plupart de ces éléments, mais séparés, selon la technique de vue éclatée. Un IPN de charpente métallique 38 supporte donc des pannes horizontales 40 sur lesquelles sont placés plusieurs ensembles de profilés 100 de façon inclinée dans le sens de pente de la toiture. Ils supportent chacun, de chaque côté, le bord d'un panneau 5, à savoir un panneau solaire, et permettent de recevoir également, en dessous des panneaux solaires, des panneaux isolants 7, au-dessus des pannes 40. Le montage des panneaux 5 sur les ensembles de profilés 100 se complète par une parclose 6 pour chaque ensemble de profilés placé au milieu et au-dessus de l'ensemble de profilés. Enfin, les tôles intermodules 9 sont placées horizontalement sur les parties inférieures et supérieures des panneaux 5, entre ceux-ci.Referring to Figure 1, the set of profiles is mounted on a metal roof structure consisting of IPNs 38 acting as chevrons and bearing horizontal failures 40 placed horizontally. On the latter, are fixed, at intervals determined according to the width of solar panels 5 to be installed, sets of profiles 100 whose function is to support and maintain these solar panels 5. This construction is completed with 9 intermodule plates placed parallel to the purlins 40 on the lower and upper edges of the panels 5. This roof can be completed with insulating panels 7 placed below the panels 5 and above the horizontal purlins 40. Referring to Figure 2, there are most of these elements, but separated, according to the exploded view technique. An IPN metal frame 38 therefore supports horizontal failures 40 on which are placed several sets of profiles 100 inclined in the direction of slope of the roof. They each support, on each side, the edge of a panel 5, namely a solar panel, and can also receive, below the solar panels, insulating panels 7, above the purlins 40. The mounting of the panels 5 on the sets of profiles 100 is completed by a bead 6 for each set of profiles placed in the middle and above the set of profiles. Finally, the intermodule plates 9 are placed horizontally on the lower and upper parts of the panels 5, between them.
En référence à la figure 3, un ensemble de profilés selon l'invention comprend principalement une partie inférieure constituée d'un profilé inférieur 1 qui est à fixer sur une panne horizontale 40, par exemple au moyen de crochets 8. Il possède des bords ayant des extrémités 12 portant des pointes 13 faisant saillie sur le dessus dans le but de bloquer des panneaux isolants 7. Une lame d'air peut ainsi circuler entre ces derniers et les panneaux solaires 5. Dans ce profilé inférieur 1 est fixé un profilé central 2 par sa partie inférieure 21. Plus exactement cette dernière est pincée entre les deux parties verticales d'une pince 11 du profilé inférieur 1. Le profilé central 2 se complète d'une partie supérieure 22 qui possèdent des bords inclinés vers le bas 23 destinés à la fixation d'une partie supérieure 22. Le profilé central 2 se complète d'une partie centrale 4 constituée de deux barrettes en polyamide, dans le but de constituer une rupture de pont thermique entre la partie inférieure 21 et la partie supérieure 22. Cette rupture de pont thermique peut également être placée ailleurs entre la partie supérieure 3 et la partie inférieure 1. Des pattes 25 faisant saillie latéralement sont également prévues pour constituer des moyens d'espacement de manière à laisser un espace entre les panneaux isolants 7 et les panneaux solaires 5 et/ou la fixation de panneaux isolants 7, en coopération avec les pointes 13 du profilé inférieur 1.Referring to Figure 3, a set of profiles according to the invention mainly comprises a lower portion consisting of a lower profile 1 which is to be fixed on a horizontal failure 40, for example by means of hooks 8. It has edges having ends 12 carrying pins 13 projecting on the top in order to block insulating panels 7. A blade of air can flow between them and the solar panels 5. In this lower section 1 is fixed a central section 2 by its lower part 21. More exactly the latter is clamped between the two vertical parts of a clamp 11 of the lower profile 1. The central section 2 is completed by an upper portion 22 which have downwardly inclined edges 23 intended for the fixation of an upper portion 22. The central section 2 is completed by a central portion 4 consisting of two polyamide bars, in order to constitute a thermal break between the lower portion 21 and the upper portion 22. This rupture The thermal bridge may also be placed elsewhere between the upper part 3 and the lower part 1. Legs 25 projecting laterally are also provided to form spacing means so as to leave a space between the insulating panels 7 and the solar panels. 5 and / or the fixing of insulating panels 7, in cooperation with the tips 13 of the lower profile 1.
On note que la partie supérieure 22 du profilé central 2 peut être percée latéralement pour laisser des câbles électriques de liaison entre les panneaux solaires.It is noted that the upper portion 22 of the central section 2 may be pierced laterally to leave electrical connecting cables between the solar panels.
L'ensemble de profilés selon l'invention se complète d'un profilé supérieur 3, qui a une forme plus complexe que les autres et notamment des moyens de gouttières inférieur et supérieur et une cavité centrale pouvant recevoir une gouttière interprofilés 10. En effet, si plusieurs ensembles de profilés sont mis bout à bout le long de la ligne de pente d'une toiture, une gouttière interprofilés 10, de préférence en polymère, peut être insérée à la fois dans la cavité interne 34 de chacun des deux ensembles de profilés mis bout à bout, dans le but d'assurer l'étanchéité au niveau de la jonction de ces deux ensembles de profilés mis bout à bout. Les moyens de gouttières sont constitués, pour ce profilé supérieur 3, par deux gouttières latérales inférieures 33 placées dans le prolongement d'une partie inclinée vers le bas 31, qui est placée sur ou contre la partie inclinée vers le bas 23 du profilé central, dans le but d'y mettre des moyens de fixation, par exemple des vis auto-foreuses. Deux gouttières latérales supérieures 33 sont prévues de part et d'autre du profilé supérieur 3. Elles comportent chacune une surface d'appui 36,37 sur laquelle repose une des extrémités d'une tôle intermodule 9 de manière à incliner cette dernière. La partie supérieure du profilé supérieur se complète de deux coins de positionnement 35 ouverts sur le côté et vers le haut pour recevoir la base inférieure du côté de chacun des panneaux solaires à positionner de part et d'autre de l'ensemble de profilés.The set of profiles according to the invention is completed by an upper section 3, which has a more complex shape than the others and in particular means of lower and upper gutters and a central cavity that can receive an interprofiled gutter 10. In fact, if several sets of profiles are placed end-to-end along the slope line of a roof, an interprofiled gutter 10, preferably made of polymer, can be inserted both into the cavity internal 34 of each of the two sets of profiles put end to end, in order to ensure sealing at the junction of these two sets of profiles put end to end. The gutter means are constituted, for this upper profile 3, by two lower side gutters 33 placed in the extension of a downwardly inclined portion 31, which is placed on or against the downwardly inclined portion 23 of the central section, for the purpose of putting fastening means, for example self-drilling screws. Two upper side gutters 33 are provided on either side of the upper profile 3. They each comprise a bearing surface 36,37 on which rests one end of an intermodule plate 9 so as to tilt the latter. The upper part of the upper profile is completed by two positioning wedges 35 open on the side and upwards to receive the lower base on the side of each of the solar panels to be positioned on either side of the set of profiles.
Enfin, l'ensemble de profilés ainsi constitué est complétée par une parclose 6 placée au-dessus du bord des deux panneaux solaires 5 adjacents et recouvrant entièrement l'espace entre ces derniers, de manière assurer l'étanchéité à ce niveau. La parclose 6 peut être fixée également par des vis auto-foreuses .Finally, the set of profiles thus formed is completed by a bead 6 placed above the edge of the two adjacent solar panels 5 and completely covering the space between them, so as to seal at this level. The baffle 6 can also be fixed by self-drilling screws.
La figure 4 montre en détail le profilé supérieur, notamment ces deux gouttières latérales inférieures 32, qui font saillies, de part et d'autre des parties inclinées vers le bas 31. Elle montre également la cavité centrale 34 sans la gouttière interprofilés, représentée sur la figure 3. On y distingue également les deux gouttières latérales supérieures 33 ainsi que les surfaces d'appui 36,37 et les deux coins de positionnement 35 destinés à recevoir les panneaux solaires à fixer. Les gouttières supérieures latérales 33 permettent d'une part de récupérer l'eau des tôles intermodules 9 et d'autre part de récupérer l'eau ayant réussi à s'infiltrer entre les panneaux solaires 5. Ainsi l'eau provenant des gouttières 33 et arrivant à s'infiltrer à la jonction de deux profilés 3 tombe sur la gouttière interprofilée 10 qui renvoie elle-même l'eau dans la partie centrale creuse 34.FIG. 4 shows in detail the upper profile, in particular these two lower lateral gutters 32, which project on either side downwardly inclined portions 31. It also shows the central cavity 34 without the interlocked gutter, shown in FIG. 3. It also distinguishes the two upper lateral gutters 33 as well as the bearing surfaces 36, 37 and the two corners. positioning means 35 for receiving the solar panels to be fixed. The upper lateral gutters 33 allow on the one hand to recover the water of the intermodule plates 9 and on the other hand to recover the water having succeeded in infiltrating between the solar panels 5. Thus the water from the gutters 33 and arriving to infiltrate at the junction of two sections 3 falls on the interprofilée gutter 10 which itself returns the water in the central hollow portion 34.
On note que les gouttières latérales inférieures 32, les gouttières latérales 33 et la gouttière interprofilés 10 ont une forme concave, c'est-à-dire avec des rebords qui remontent vers le haut pour assurer la fonction de gouttière et de canalisation des eaux éventuellement recueillies.It should be noted that the lower side gutters 32, the lateral gutters 33 and the gutter 10 have a concave shape, that is to say with rims which rise upwards to ensure the function of gutter and water channeling collected.
Une fois le profilé central 2 inséré dans le profilé inférieur 1, le profilé supérieur 3 est fixé sur le profilé central 2, à l'aide de vis auto-foreuse au niveau des bords inclinés vers le bas 23 et 31, des respectivement profilés central 2 et profilé supérieur 3.Once the central profile 2 inserted into the lower profile 1, the upper section 3 is fixed on the central section 2, using self-drilling screws at the downwardly inclined edges 23 and 31, respectively central sections. 2 and upper profile 3.
En référence maintenant à la figure 5, on peut apercevoir un autre mode de réalisation préféré de la présente invention, la sortie 42 étant située vers le haut du toit, l'air circulant entre les panneaux isolants 7 et les panneaux solaires 5. Une extrémité 43 d'un conduit 44 débouche dans cette sortie 42, l'extrémité 43 se situant dans un plan 46 correspondant au plan supérieur des panneaux isolants 7 et les conduits 44 sont disposés vers le milieu de ces derniers dans ce cas. Les conduits 44 sont reliés à un seul tube d'extraction 45 permettant d'extraire l'air vers un système d'extraction motorisé (non représenté) . Les conduits 44 supportent également le tube d'extraction 45 qui supporte lui-même des capteurs de température (non représentés) . Des capteurs de température sont également incorporés au niveau des panneaux solaires (5) et reliés à un système d'asservissement du débit d'air. L'ensemble de profilés permet de construire une toiture en trois couches : panneaux solaires, lame d'air rafraîchissante, panneaux d'isolation, le tout étant complètement étanche, de plus un système de récupération d'air y est facilement intégrable. Referring now to FIG. 5, another preferred embodiment of the present invention can be seen, the outlet 42 being located towards the top of the roof, the air flowing between the panels insulators 7 and solar panels 5. An end 43 of a conduit 44 opens into this outlet 42, the end 43 being in a plane 46 corresponding to the upper plane of the insulating panels 7 and the conduits 44 are arranged towards the middle of the these in this case. The conduits 44 are connected to a single extraction tube 45 for extracting the air to a motorized extraction system (not shown). The conduits 44 also support the extraction tube 45 which itself supports temperature sensors (not shown). Temperature sensors are also incorporated in the solar panels (5) and connected to an air flow control system. The set of profiles allows to build a roof in three layers: solar panels, cooling air blade, insulation panels, the whole being completely sealed, moreover an air recovery system is easily integrated.
