Description

Pièce de fixation pour l'assemblage d'un module, notamment photovoltaïque, sur une tôle nervurée, assemblage et utilisation pour la réalisation d'une couverture de bâtiment et procédé de fabrication associé. Fastener for assembling a module, particularly photovoltaic, on a ribbed sheet, assembly and use for the realization of a building cover and associated manufacturing method.
L'invention concerne principalement une pièce de fixation destinée à assembler un module sur une tôle nervurée.The invention mainly relates to a fastener for assembling a module on a ribbed sheet.
L'invention porte également sur l'assemblage du module sur la tôle nervurée, sur son utilisation pour fabriquer une couverture de bâtiment et sur le procédé de fabrication associé. Le module peut être un module photovoltaïque sans toutefois y être limité.The invention also relates to the assembly of the module on the ribbed sheet, its use to manufacture a building cover and the associated manufacturing process. The module can be a photovoltaic module without being limited thereto.
Les modules photovoltaïques présentent généralement la forme d'un cadre portant des cellules photovoltaïques. Ces modules sont rapportés sur la couverture des bâtiments et solidarisés à cette couverture par des moyens de fixation appropriés.Photovoltaic modules generally have the form of a frame carrying photovoltaic cells. These modules are reported on the cover of buildings and secured to this cover by appropriate means of attachment.
Il est connu de réaliser les couvertures de toit avec des tôles nervurées, par exemple en acier galvanisé prélaqué, dont les bords se chevauchent pour assurer l'étanchéité du système.It is known to make the roof covers with ribbed sheets, for example galvanized steel prepainted, whose edges overlap to seal the system.
Il est, par ailleurs, connu notamment de DE202007005995, EP1267418, WO2007/093421 et DE202008007662 des pièces de fixation destinées à assembler un module sur une tôle nervurée.

These parts, however, require the installation of the roof at first and the assembly of the modules on the roof in a second time.
L'assemblage de modules photovoltaïques sur une toiture en tôle nervurée préalablement posée implique l'intervention de deux corps de métier ce qui engendre des problèmes de coordination sur le chantier ainsi que des temps de réalisation de la couverture et des coûts associés trop élevés.The assembly of photovoltaic modules on a ribbed sheet metal roof previously laid implies the intervention of two trades which causes problems of coordination on the site as well as times of completion of coverage and associated costs too high.
Par ailleurs, la réalisation d'un tel assemblage doit permettre de continuer à assurer l'étanchéité de la couverture du bâtiment, ce que ne favorisent pas les conditions d'assemblage sur chantier.Moreover, the realization of such an assembly should allow to continue to ensure the tightness of the building cover, which do not favor the conditions of assembly on site.
Naturellement, la solidité de l'assemblage et sa résistance aux sollicitations mécaniques engendrées par exemple par le vent et le poids de la neige doivent être assurées.Naturally, the strength of the assembly and its resistance to mechanical stresses generated for example by the wind and the weight of the snow must be ensured.

Ces joints 13,14 permettront de préserver l'étanchéité du système comme il sera décrit plus loin.The first 6 and second 11 attachment zones of the part 1 on the sheet each comprise a seal 13,14, for example neoprene, which extends over the width of the fastener 1. The seals 13,14 are glued on the lower face of the room 1 at the area considered. These seals 13,14 will preserve the tightness of the system as will be described later.
Les parties obliques 6, 10 et 12 de la pièce de fixation 1 sont sensiblement parallèles entre elles. On se réfère à présent aux figures 3 et 5 pour décrire la fonctionnalité et le positionnement de la pièce de fixation 1 dans l'environnement de l'assemblage du module sur la tôle nervurée.The oblique parts 6, 10 and 12 of the fastener 1 are substantially parallel to each other. Referring now to Figures 3 and 5 to describe the functionality and positioning of the fastener 1 in the environment of the assembly of the module on the ribbed sheet.
La tôle nervurée 20 est, comme la pièce de fixation, en acier comportant un revêtement métallique ou organique, ou faite de tout autre matériau adapté, de préférence métallique.The corrugated plate 20 is, like the fastener, steel having a metal or organic coating, or made of any other suitable material, preferably metal.
Dans l'ensemble du texte, on entendra par tôle nervurée 20, une tôle comportant une alternance de plages 22 et de nervures de rigidification 21 , dont les nervures 21 peuvent être de forme trapézoïdale, ondulée, sinusoïdale ou encore en oméga. Dans cet exemple, les nervures 21 sont trapézoïdales et les plages 22 comportent elles-mêmes des nervures de faible hauteur formant raidisseurs qui n'entrent pas dans le cadre de l'invention.Throughout the text, ribbed sheet 20 will be understood to mean a sheet comprising an alternation of beaches 22 and stiffening ribs 21, whose ribs 21 may be trapezoidal, corrugated, sinusoidal or omega-shaped. In this example, the ribs 21 are trapezoidal and the 22 beaches themselves comprise ribs of low height forming stiffeners that are not part of the invention.
Les deux bords latéraux de la tôle 23,24 comportent chacun une nervure tronquée respectivement 21a,21b. Chaque nervure centrale 21 comporte une partie supérieure plane 25 et deux flancs inclinés 26,27 conférant la forme en oméga. Pour chaque nervure tronquée 21a,21b située au niveau d'un bord latéral 23,24, le deuxième flanc incliné 28 est de longueur inférieure au flanc opposé 26,27 de la nervure considérée 21a,21b.The two lateral edges of the sheet 23,24 each comprise a truncated rib respectively 21a, 21b. Each central rib 21 has a planar upper portion 25 and two inclined flanks 26,27 conferring the omega shape. For each truncated rib 21a, 21b located at a lateral edge 23,24, the second inclined flank 28 is of shorter length than the opposite flank 26,27 of the considered rib 21a, 21b.
De façon préférentielle, les nervures 21 a, 21b de bords latéraux opposés 23,24 sont symétriquement semblables de sorte que d'une part, la tôle 20 n'est soumise à aucun sens d'installation et que d'autre part, lors de la réalisation d'une couverture de bâtiment, deux tôles adjacentes sont installées par recouvrement de leurs bords latéraux et plus précisément par appui de contact d'une nervure tronquée 21a du premier bord latéral 23 d'une première tôle sur la nervure tronquée 21b du deuxième bord latéral 24 de la tôle adjacente. De cette façon, l'étanchéité entre deux tôles adjacentes est mieux assurée.Preferably, the ribs 21a, 21b of opposite lateral edges 23, 24 are symmetrically similar so that, on the one hand, the sheet 20 is not subjected to any direction of installation and that on the other hand, when the realization of a building cover, two adjacent sheets are installed by overlapping their lateral edges and more precisely by contacting contact of a truncated rib 21a of the first lateral edge 23 of a first sheet on the truncated rib 21b of the second lateral edge 24 of the adjacent sheet. In this way, the seal between two adjacent sheets is better ensured.
Comme représenté sur les figures 3 et 5, une tôle comporte plusieurs pièces de fixation par exemple quatre par modules (figures 3 et 4). Chaque pièce de fixation 1 s'étend perpendiculairement aux nervures 21 depuis la nervure tronquée 21a,21b du bord latéral correspondant 23, 24 jusqu'à une nervure 21 adjacente.As shown in Figures 3 and 5, a sheet has several fasteners for example four per module (Figures 3 and 4). Each fastener 1 extends perpendicularly to the ribs 21 from the truncated rib 21a, 21b of the corresponding lateral edge 23, 24 to an adjacent rib 21.
Le surplomb 2 formant zone de fixation 4 et de support 3 du module 30 surplombe la nervure tronquée 21b depuis laquelle s'étend la pièce de fixation 1 , en laissant un espace entre la zone plane de support 3 et le sommet de la nervure tronquée 21b. Cet espace autorise l'assemblage de deux tôles adjacentes comme décrit précédemment par superposition des nervures tronquées 21a,21b des bords latéraux respectifs 23,24 de ces deux tôles.Overhang 2 forming attachment zone 4 and support 3 of module 30 overhangs truncated rib 21b from which attachment piece 1 extends, leaving a gap between the flat support zone 3 and the top of the truncated rib 21b. . This space allows the assembly of two adjacent sheets as described above by superposition of the truncated ribs 21a, 21b of the respective side edges 23,24 of these two sheets.
La première zone de fixation 6 de la pièce 1 sur la tôle 20 est en appui de contact sur la partie inférieure du flanc 26 de la nervure tronquée 21b et fixée à ce flanc 26 par exemple par une vis traversante 31. L'étanchéité est assurée par la présence du joint 13 précédemment décrit.The first attachment zone 6 of the part 1 on the sheet 20 is in contact abutment on the lower part of the sidewall 26 of the truncated rib 21b and fixed to this sidewall 26 for example by a through screw 31. The sealing is ensured by the presence of the seal 13 previously described.
La position de cette zone de fixation 6 est très avantageuse puisqu'elle ne contraint pas l'écoulement de l'eau provenant des intempéries et s'écoulant le long de la tôle 1 au niveau des plages 22 en évitant ainsi toute rétention d'eau. L'eau n'étant pas au contact de la vis de façon statique, il n'y a pas de risques d'infiltration.The position of this fastening zone 6 is very advantageous since it does not constrain the flow of water from the weather and flows along the sheet 1 at the beaches 22 thus avoiding any water retention. . The water is not in contact with the screw statically, there is no risk of infiltration.
La deuxième zone de fixation 11 est en appui de contact sur la partie supérieure plane 25 de la nervure 21 et fixée à cette partie plane 25 par exemple par une vis traversante 32. L'étanchéité est assurée par la présence du joint 14 précédemment décrit. La partie oblique 12 en aval de la partie plane 25 épouse le flanc descendant 26 de la nervure 21.The second attachment zone 11 is in contact abutment on the flat upper part 25 of the rib 21 and fixed to this flat part 25 for example by a through screw 32. The seal is provided by the presence of the seal 14 previously described. The oblique portion 12 downstream of the flat portion 25 matches the downward flank 26 of the rib 21.
Le module photovoltaïque 30 comporte un cadre 33 qui porte des cellules photovoltaïques 34 de plus faible épaisseur que le cadre 33. Comme visible sur la figure 5, le module 30 est en appui, par son cadre 33, sur la pièce de fixation 1 au niveau de la zone de support 3. Et le cadre 33 est fixé à la pièce de fixation 1 au niveau de sa zone de fixation 4 par exemple au moyen d'une vis traversante 35a. La vis 35b située d'un coté du module est positionnée au-dessus du niveau de la vis 35a située de l'autre coté du module de sorte que lors de la réalisation de la couverture du bâtiment, les cadres 33 des modules 30 de deux assemblages adjacents 40 puissent être en appui de contact. Alternativement, la vis 35b est positionnée en avant ou en arrière du plan de coupe de la figure 5. Cet appui de contact est également rendu possible par la position de ces cadres 33 relativement aux nervures tronquées 21 a, 21b. Comme visible sur la figure 5, les cellules photovoltaïques 34 sont en appui de contact sur la zone de support 8. Cette zone de support 8 vient renforcer la résistance mécanique de l'assemblage, permettant ainsi de marcher sur les cellules photovoltaïques lors de l'assemblage de la toiture ou la maintenance de celles-ci. Sur la figure 5, un connecteur électrique 41 est raccordé aux cellules photovoltaïques 34. Les connecteurs électriques sont des éléments connus en eux-mêmes qui sont généralement pré-assemblés par collage et connectés électriquement avec les cellules photovoltaïques 34 lors de la fabrication des cellules. Comme visible sur cette figure, le connecteur 41 est muni de deux bornes de raccordement 36,37 qui permettent de relier en série comme en parallèle les cellules photovoltaïques de deux modules adjacents par l'intermédiaire de câbles 38, 39. Pour réaliser un assemblage 40 tel que celui représenté sur la figure 4 comportant deux modules 40 fixés sur une tôle 20, il suffit de positionner les pièces de fixation sur la tôle 20, de les fixer sur cette tôle, par exemple par vissage, au niveau de leurs zones de fixation respectives 6,11 (figure 3) puis de positionner le cadre du module 33 sur la zone de support 3 de la pièce de fixation 1 , et enfin de solidariser le module 30 à la pièce de fixation 1 par vissage au niveau des zones de fixation 4 prévus à cet effet. La pièce de fixation 1 aura été préalablement configurée pour que les cellules photovoltaïques soient en appui sur la zone d'appui 8. Quatre pièces de fixation par module sont suffisantes pour assurer la solidité du système. Il est entendu qu'il peut être utilisé un nombre de pièces de fixation supérieur à quatre.The photovoltaic module 30 comprises a frame 33 which carries photovoltaic cells 34 of smaller thickness than the frame 33. As can be seen in FIG. 5, the module 30 bears, by its frame 33, on the fastener 1 at the of the support zone 3. And the frame 33 is fixed to the fastener 1 at its attachment zone 4 for example by means of a through screw 35a. The screw 35b located on one side of the module is positioned above the level of the screw 35a located on the other side of the module so that when making the building cover, the frames 33 of the modules 30 of two adjacent assemblies 40 can be in contact support. Alternatively, the screw 35b is positioned in front of or behind the cutting plane of FIG. 5. This contact support is also made possible by the position of these frames 33 relative to the truncated ribs 21a, 21b. As can be seen in FIG. 5, the photovoltaic cells 34 are in contact support on the support zone 8. This support zone 8 reinforces the mechanical strength of the assembly, thus making it possible to walk on the photovoltaic cells during the assembly of the roof or maintenance thereof. In FIG. 5, an electrical connector 41 is connected to the photovoltaic cells 34. The electrical connectors are elements known per se which are generally pre-assembled by gluing and electrically connected with the photovoltaic cells 34 during the manufacture of the cells. As visible in this figure, the connector 41 is provided with two connection terminals 36, 37 which make it possible to connect in series, as in parallel, the photovoltaic cells of two adjacent modules by means of cables 38, 39. To make an assembly 40 such as that represented in FIG. 4 comprising two modules 40 fixed to a sheet 20, it suffices to position the fasteners on the sheet 20, to fasten them to this sheet, for example by screwing, of their respective fastening zones 6, 11 (FIG. 3) then to position the frame of the module 33 on the support zone 3 of the fastener 1, and finally to secure the module 30 to the fastener 1 by screwing to the level of the fixing zones 4 provided for this purpose. The fastener 1 will have been previously configured so that the photovoltaic cells are resting on the support zone 8. Four fasteners per module are sufficient to ensure the strength of the system. It is understood that it can be used a number of fasteners greater than four.
La réalisation d'un tel assemblage en atelier favorise le contrôle de l'étanchéité de l'assemblage au niveau des première 6 et deuxième 11 zones de fixation.The realization of such a workshop assembly promotes control of the tightness of the assembly at the first 6 and second 11 attachment areas.
Cet assemblage 40 est ensuite transporté sur chantier où il est solidarisé à la structure du bâtiment.This assembly 40 is then transported to the site where it is attached to the building structure.
Son transport est facile du fait de la configuration de l'assemblage 40 puisque la largeur d'un empilement d'assemblage correspondra à la largeur de la tôle nervurée 20.Its transport is easy because of the configuration of the assembly 40 since the width of an assembly stack will correspond to the width of the corrugated sheet 20.
Enfin, l'installation sur chantier est également simple puisque réalisée par recouvrement des bords latéraux des tôles adjacentes et solidarisation de ces bords, comme c'est actuellement le cas lors de la réalisation d'une couverture sèche faite uniquement de tôles nervurées. L'étanchéité entre deux tôles adjacentes est donc assurée.Finally, the installation on site is also simple since achieved by covering the side edges of the adjacent sheets and securing these edges, as is currently the case when producing a dry cover made only of ribbed sheets. Sealing between two adjacent sheets is ensured.
La présence des première 6 et deuxième 11 zones de fixations uniquement dans des zones de la tôle éloignées du cadre 33 du module permet de mettre deux modules adjacents en appui de contact lors du recouvrement des bords latéraux ou d'extrémités de deux tôles adjacentes. Cet appui de contact entre les modules permet d'accroître le rendement énergétique de l'installation.The presence of the first 6 and second 11 attachment zones only in areas of the sheet remote from the frame 33 of the module makes it possible to put two adjacent modules in contact support when covering the lateral edges or ends of two adjacent sheets. This contact support between the modules makes it possible to increase the energy efficiency of the installation.
Par ailleurs, la pièce de fixation, telle que décrite ci-dessus, offre à l'installation les avantages suivants :In addition, the fastener, as described above, offers the installation the following advantages:
- les cadres 33 des modules 30 de deux assemblages adjacents 40 étant en appui de contact et les vis traversantes 35a, 35b étant situées sur le coté du module, le démontage délictueux d'un module est rendu particulièrement difficile. Cela contribue à la pérennité de l'installation. - Les perçages réalisés dans la tôle nervurée 20 pour assurer la fixation de la pièce de fixation 1 sont faits dans des zones non soumises à la circulation d'eau le long de la tôle en cas d'intempéries. Par ailleurs, l'étanchéité au niveau de ces orifices est préservée par la présence des joints d'étanchéité.the frames 33 of the modules 30 of two adjacent assemblies 40 being in contact support and the through screws 35a, 35b being located on the side of the module, the disassembly of a criminal module is made particularly difficult. This contributes to the sustainability of the installation. - The holes made in the ribbed plate 20 to ensure the attachment of the fastener 1 are made in areas not subjected to the circulation of water along the sheet in case of bad weather. Moreover, the seal at these orifices is preserved by the presence of the seals.
Bien entendu, la pièce de fixation de l'invention ainsi que l'assemblage peuvent être réalisés pour des modules autres que photovoltaïques, tels que, par exemple, des modules solaires thermiques, des panneaux sandwich, des parements de façade de type cassette.Of course, the fastener of the invention as well as the assembly can be made for modules other than photovoltaic modules, such as, for example, solar thermal modules, sandwich panels, facings cassette type facade.
Bien entendu, la pièce de fixation de l'invention ainsi que l'assemblage peuvent être réalisés pour des tôles nervurées de configuration différente de celle présentée dans l'exemple précédent. La pièce de fixation sera adaptée à la géométrie des nervures et des plages. En particulier, les parties 6, 11 et 12 de cette pièce de fixation épouseront les nervures. On peut également envisager de remplacer la tôle nervurée par un panneau sandwich.Of course, the fastener of the invention and the assembly can be made for ribbed sheets of different configuration than that presented in the previous example. The fastener will be adapted to the geometry of the ribs and beaches. In particular, the parts 6, 11 and 12 of this fastener will fit the ribs. It is also possible to consider replacing the ribbed sheet with a sandwich panel.
Il peut également être prévu que la tôle nervurée constitue déjà la couverture du bâtiment et que les pièces de fixation et les modules soient fixés sur cette couverture déjà existante. It can also be expected that the ribbed plate is already the building cover and that the fasteners and modules are fixed on the existing cover.
