Description
SYSTEME DE FIXATION DE PANNEAUX SOLAIRES SUR UNE TOITURE L'invention concerne un système de fixation de panneaux solaires, notamment photovoltaïques ou thermiques, sur une toiture.The invention relates to a system for fixing solar panels, particularly photovoltaic or thermal, on a roof.
Certaines toitures de maisons ou d'immeubles sont équipées de tôles de couverture présentant des nervures parallèles. Les installations photovoltaïques ou thermiques montées sur ces toitures sont généralement fixées au moyen de rails perpendiculaires ou parallèles aux nervures par l'intermédiaire de cavaliers montés le long des nervures et fixés à la charpente de la toiture. Lesdits cavaliers présentent une forme correspondant à la forme externe des nervures afin de répartir les efforts dus à la charge globale exercée notamment par le poids des panneaux solaires et des charges dues aux conditions climatiques. De tels cavaliers, notamment connus de FR-A-2 962 194, comprennent généralement une aile verticale perforée d'un trou oblong à travers lequel un élément de fixation d'une partie du rail est inséré. L'élément de fixation peut notamment être un boulon dont la tête est insérée dans une partie latérale du rail pour solidariser le rail au cavalier. De tels cavaliers et rails présentent une géométrie qui implique des contraintes de flexion importantes sur l'aile des cavaliers, car la charge globale appliquée aux rails exerce un effort décalé sur un seul côté des ailes.Some roofs of houses or buildings are equipped with cover plates with parallel ribs. The photovoltaic or thermal installations mounted on these roofs are generally fixed by means of rails perpendicular or parallel to the ribs by means of jumpers mounted along the ribs and fixed to the frame of the roof. Said jumpers have a shape corresponding to the external shape of the ribs in order to distribute the forces due to the overall load exerted in particular by the weight of solar panels and loads due to weather conditions. Such riders, in particular known from FR-A-2 962 194, generally comprise a vertical wing perforated with an oblong hole through which a fastener of a part of the rail is inserted. The fastening element may in particular be a bolt whose head is inserted into a lateral part of the rail to secure the rail to the rider. Such riders and rails have a geometry that involves significant bending stresses on the rider's wing, because the overall load applied to the rails exerts a shifted effort on one side of the wings.
C'est à ces inconvénients qu'entend remédier l'invention en proposant un nouveau système de fixation de panneaux solaires sur une toiture, dont la structure permet une meilleure répartition de la charge globale sur les cavaliers. A cet effet, l'invention concerne un système de fixation de panneaux solaires sur une toiture, la toiture comprenant des pannes, qui forment la charpente de la toiture, sur lesquelles sont fixées des tôles de couverture présentant des nervures parallèles orientées selon une direction perpendiculaire aux pannes, le système de fixation comprenant des cavaliers montés sur les nervures et fixés aux pannes, et des rails de support des panneaux solaires, chacun des rails étant fixé à plusieurs cavaliers montés sur une même nervure. Ce système de fixation est caractérisé en ce que chaque cavalier comprend deux ailes adaptées pour prendre en étau un rail de support et en ce que les rails de support sont fixés aux cavaliers par des boulons insérés dans des trous ménagés dans les ailes des cavaliers et dans les rails de support. Grâce à l'invention, la charge globale transmise par l'intermédiaire des rails s'exerce sur les deux ailes des cavaliers de façon sensiblement égale, ce qui permet d'éviter des contraintes de flexion dans l'une des ailes et une possible fragilisation du système de fixation.It is these drawbacks that the invention intends to remedy by proposing a new system for fixing solar panels on a roof, whose structure allows a better distribution of the overall load on the riders. To this end, the invention relates to a system for fixing solar panels on a roof, the roof comprising failures, which form the roof structure, on which are fixed cover plates having parallel ribs oriented in a perpendicular direction the purlins, the fixing system comprising jumpers mounted on the ribs and fixed to the purlins, and support rails of the solar panels, each of the rails being fixed to several jumpers mounted on the same rib. This fastening system is characterized in that each rider comprises two wings adapted to grip a support rail and in that the support rails are fixed to the riders by bolts inserted into holes in the flanges of the riders and in the support rails. Thanks to the invention, the overall load transmitted via the rails is exerted on the two wings of the riders in a substantially equal manner, which avoids bending stresses in one of the wings and a possible embrittlement fixing system.
Selon des aspects avantageux mais non obligatoires de l'invention, un tel système de fixation de panneaux solaires peut incorporer une ou plusieurs des caractéristiques suivantes, prises dans toute combinaison techniquement admissible : - Les ailes sont adaptées pour exercer une force de serrage sur le rail, alors que le rail est monté en force entre les ailes de chaque cavalier. - La distance, prise selon une direction transversale des rails, entre les ailes d'un cavalier, lorsqu'aucun rail de support n'est monté entre les ailes de ce cavalier, est légèrement inférieure à la largeur des rails, prise selon la direction transversale des rails. - Les cavaliers sont en acier. - Les rails de support sont en acier. - Les trous des ailes des cavaliers dans lesquels les boulons de fixation du rail sont insérés sont oblongs et s'étendent parallèlement aux rails. - Les trous des rails dans lesquels les boulons de fixation du rail sont insérés sont oblongs et s'étendent perpendiculairement au plan de la toiture. - Les trous oblongs des rails sont répartis à des intervalles réguliers sur la longueur du rail. - Les trous de passage des boulons dans les rails sont ménagés dans des parois des rails qui sont parallèles aux ailes des cavaliers. - Les cavaliers comprennent des raidisseurs formés par des parties bombées des cavaliers. L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un système de fixation de panneaux solaires sur une toiture, faite à titre d'exemple non limitatif et en référence aux dessins annexés dans lesquels : - la figure 1 est une vue en perspective d'une partie d'une toiture sur laquelle sont montés deux panneaux solaires au moyen d'un système de fixation conforme à l'invention ; - la figure 2 est une vue de côté selon la flèche Il à la figure 1, du système de fixation de la figure 1 ; - la figure 3 est une vue en perspective d'un cavalier appartenant au système de fixation des figures 1 et 2 monté sur une tôle de couverture ; - la figure 4 est une vue en perspective similaire à la figure 3, un rail appartenant au système de fixation selon l'invention étant fixé au cavalier de la figure 3 ; - la figure 5 est une vue de côté selon la flèche V, de la toiture, d'un panneau solaire et du système de fixation des figures 1 et 2 ; - la figure 6 est une vue en perspective d'un cavalier appartenant à un système de fixation conforme à l'invention.According to advantageous but non-mandatory aspects of the invention, such a solar panel fixing system may incorporate one or more of the following features, taken in any technically permissible combination: - The wings are adapted to exert a clamping force on the rail , while the rail is mounted in force between the wings of each rider. - The distance, taken in a transverse direction of the rails, between the wings of a rider, when no support rail is mounted between the wings of this rider, is slightly less than the width of the rails, taken in the direction transverse rails. - The riders are made of steel. - The support rails are made of steel. - The flange holes of the riders in which the rail fastening bolts are inserted are oblong and extend parallel to the rails. - The holes in the rails in which the rail fastening bolts are inserted are oblong and extend perpendicular to the plane of the roof. - The oblong holes of the rails are distributed at regular intervals along the length of the rail. - The bolt holes in the rails are formed in walls of the rails that are parallel to the riders' wings. - The riders include stiffeners formed by bulging parts of the riders. The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of a system for fixing solar panels on a roof, made by way of non-limiting example and in reference to the accompanying drawings in which: - Figure 1 is a perspective view of a portion of a roof on which are mounted two solar panels by means of a fastening system according to the invention; - Figure 2 is a side view along the arrow II in Figure 1, the fastening system of Figure 1; - Figure 3 is a perspective view of a jumper belonging to the fastening system of Figures 1 and 2 mounted on a cover plate; - Figure 4 is a perspective view similar to Figure 3, a rail belonging to the fastening system according to the invention being fixed to the jumper of Figure 3; - Figure 5 is a side view along the arrow V, the roof, a solar panel and the fastening system of Figures 1 and 2; - Figure 6 is a perspective view of a jumper belonging to a fastening system according to the invention.
Le système de fixation S représenté aux figures 1 à 6 est destiné à solidariser des panneaux solaires 2, de préférence photovoltaïques, sur une toiture 4. En variante, les panneaux solaires 2 peuvent également être des panneaux thermiques. La toiture 4 comprend des pannes 40, qui forment la charpente de la toiture 4. Les pannes 40 sont des poutres, de préférence en acier, espacées selon une distance déterminée. Dans l'exemple décrit, les pannes 40 présentent un profilé en « H » et comprennent des bords perpendiculaires 400. Sur les pannes 40 sont fixées des tôles de couverture 42, de préférence fabriquées en acier, qui présentent des nervures 420 parallèles entre elles et à une direction longitudinale X-X'. La direction longitudinale X-X' des nervures 420 est perpendiculaire à une direction transversale Y-Y', à laquelle les pannes 40 sont parallèles. En variante, les pannes 40 peuvent présenter toute autre forme. Chaque tôle de couverture 42 comprend, entre les nervures 420, des fonds 422.The fastening system S shown in Figures 1 to 6 is intended to secure solar panels 2, preferably photovoltaic, on a roof 4. Alternatively, the solar panels 2 may also be thermal panels. The roof 4 comprises purlins 40, which form the framework of the roof 4. The purlins 40 are beams, preferably of steel, spaced at a determined distance. In the example described, the purlins 40 have an "H" profile and comprise perpendicular edges 400. On the purlins 40 are fixed cover plates 42, preferably made of steel, which have ribs 420 parallel to each other and at a longitudinal direction X-X '. The longitudinal direction X-X 'of the ribs 420 is perpendicular to a transverse direction Y-Y', at which the purlins 40 are parallel. Alternatively, the purlins 40 may have any other shape. Each cover plate 42 comprises, between the ribs 420, funds 422.
Les nervures 420 comprennent deux parois inclinées 424 et 426 et un sommet 428. Les tôles de couverture 42 reposent, par leurs fonds 422, sur un bord 400 des pannes 40. La toiture 4 définit un plan P4 parallèle aux directions Y-Y' et X-X'. Les fonds 422 sont compris dans le plan P4. Les panneaux solaires 2 sont également parallèles au plan P4.The ribs 420 comprise two inclined walls 424 and 426 and a top 428. The cover plates 42 rest, by their bottoms 422, on an edge 400 of the purlins 40. The roof 4 defines a plane P4 parallel to the directions YY 'and X- X '. Funds 422 are included in plan P4. The solar panels 2 are also parallel to the plane P4.
Le système de fixation S comprend des cavaliers 6, de préférence fabriqués en acier, montés sur les nervures 420 et fixés aux pannes 40. Les cavaliers 6 comprennent une partie centrale 60 adaptée pour se superposer au sommet 428 des nervures 420 et deux supports latéraux 62 et 64 adaptés pour s'étendre le long des parois inclinées 424 et 426. Les supports latéraux 62 et 64 sont terminés par des bords d'appui 66 et 68, qui sont en contact avec les tôles de couverture 42 au niveau des fonds 422. La hauteur de la partie centrale 60 par rapport aux bords d'appui 66 et 68 est supérieure à la hauteur des sommets 428 par rapport au fond 422, de sorte que les cavaliers 6 reposent sur les fonds 422 et non sur les sommets 428. Ceci permet d'éviter que la charge globale comprenant le poids des panneaux solaires 2, des rails 10 et les charges dues aux conditions climatiques, notamment le vent ou la neige, s'exerce sur les sommets 428, dont la résistance mécanique est inférieure à celle des fonds 422, qui sont pincés entre les bords d'appui 66 et 68 et les pannes 40. La partie centrale 60 est percée d'un trou 600 à travers lequel une vis 8 est insérée. La vis 8 passe également à travers les sommets 428 et est vissée dans les bords perpendiculaires 400. Les cavaliers 6 comprennent chacun deux ailes 70 et 72 s'étendant à angle droit à partir de la partie centrale 60 à l'opposé des supports latéraux 62 et 64. Chacune des ailes 70 et 72 comprend respectivement, à son extrémité opposée à la partie centrale 60, un trou oblong 701 et 721 s'étendant parallèlement à la direction X-X'. Le système de fixation S comprend également des rails 10 de support des panneaux solaires 2. Chaque rail 10 est monté sur plusieurs cavaliers 6 fixés sur une nervure 420. Les rails de support 10 sont de préférence fabriqués en acier. Chaque rail 10 comporte une partie inférieure centrale 101 sensiblement parallèle au fond 422, et deux parois latérales 103 et 105 s'étendant à angle droit à partir de la partie inférieure centrale 101 à l'opposé des fonds 422 lorsque les rails de support 10 sont montés sur les cavaliers 6. Les parois 103 et 105 sont parallèles aux ailes 70 et 72. Les rails 10 s'étendent parallèlement aux nervures 420 et à la direction X-X'. La direction Y-Y' forme une direction transversale aux rails 10. Les parois latérales 103 et 105 des rails 10 comprennent, à des intervalles réguliers sur la longueur des rails 10, des trous oblongs 103a et 105a qui s'étendent selon une direction Z-Z' perpendiculaire à la direction X-X' et à la direction transversale Y-Y'. La direction Z-Z' est également perpendiculaire au plan P4. Les ailes 70 et 72 s'étendent également parallèlement à la direction Z-Z'. La distance, prise selon la direction Y-Y', entre les ailes 70 et 72, lorsqu'aucun rail 10 n'est monté entre les ailes 70 et 72, est légèrement inférieure à la largeur, prise selon la direction Y-Y', des rails 70. Ainsi, lorsque le rail de support 10 est monté entre les ailes 70 et 72, celle-ci sont écartées et exercent un effort de maintien F sur les rails 10. Les rails 10 sont pris en étau de chacun de leurs côtés par les ailes 70 et 72. Les rails 10 sont montés en force entre les ailes 70 et 72 des cavaliers 6. A titre d'exemple, la distance entre les ailes 70 et 72 équivaut à 28,7 millimètres, alors que la largeur du rail 10 équivaut à 29,5 millimètres. L'effort de maintien F permet un réglage aisé du positionnement des rails 10 sur la toiture 4 avant blocage par insertion et serrage des boulons 12.The fastening system S comprises jumpers 6, preferably made of steel, mounted on the ribs 420 and fixed to the purlins 40. The jumpers 6 comprise a central portion 60 adapted to be superimposed on the top 428 of the ribs 420 and two lateral supports 62 and 64 adapted to extend along the inclined walls 424 and 426. The side supports 62 and 64 are terminated by bearing edges 66 and 68, which are in contact with the cover plates 42 at the bottoms 422. The height of the central portion 60 with respect to the bearing edges 66 and 68 is greater than the height of the vertices 428 with respect to the bottom 422, so that the jumpers 6 rest on the bottoms 422 and not on the vertices 428. prevents the global load including the weight of solar panels 2, rails 10 and loads due to climatic conditions, including wind or snow, is exerted on the vertices 428, whose mechanical strength is lower to that funds 422, which are clamped between the bearing edges 66 and 68 and the purlins 40. The central portion 60 is pierced with a hole 600 through which a screw 8 is inserted. The screw 8 also passes through the vertices 428 and is screwed into the perpendicular edges 400. The jumpers 6 each comprise two wings 70 and 72 extending at right angles from the central portion 60 opposite the lateral supports 62 and 64. Each of the wings 70 and 72 respectively comprises, at its end opposite the central portion 60, an oblong hole 701 and 721 extending parallel to the direction X-X '. The fastening system S also comprises rails 10 for supporting the solar panels 2. Each rail 10 is mounted on several jumpers 6 fixed on a rib 420. The support rails 10 are preferably made of steel. Each rail 10 has a central lower portion 101 substantially parallel to the bottom 422, and two side walls 103 and 105 extending at right angles from the central lower portion 101 opposite the bottoms 422 when the support rails 10 are mounted on the jumpers 6. The walls 103 and 105 are parallel to the wings 70 and 72. The rails 10 extend parallel to the ribs 420 and the direction X-X '. The direction YY 'forms a direction transverse to the rails 10. The side walls 103 and 105 of the rails 10 comprise, at regular intervals along the length of the rails 10, oblong holes 103a and 105a which extend in a direction ZZ' perpendicular at the direction XX 'and at the transverse direction Y-Y'. The direction Z-Z 'is also perpendicular to the plane P4. The wings 70 and 72 also extend parallel to the direction ZZ '. The distance, taken in the Y-Y 'direction, between the wings 70 and 72, when no rail 10 is mounted between the wings 70 and 72, is slightly smaller than the width, taken in the Y-Y' direction , rails 70. Thus, when the support rail 10 is mounted between the wings 70 and 72, the latter are spaced apart and exert a holding force F on the rails 10. The rails 10 are caught in the vice of each of their sides by the wings 70 and 72. The rails 10 are mounted in force between the flanges 70 and 72 of the riders 6. For example, the distance between the flanges 70 and 72 is equivalent to 28.7 millimeters, while the width rail 10 equals 29.5 millimeters. The holding force F allows easy adjustment of the positioning of the rails 10 on the roof 4 before blocking by insertion and tightening of the bolts 12.
Les panneaux solaires 2 sont fixés aux rails 10 par des moyens connus de l'homme du métier qui ne sont pas décrits ici.The solar panels 2 are attached to the rails 10 by means known to those skilled in the art which are not described here.
Pour solidariser les rails 10 aux cavaliers 6, le système de fixation S comprend des boulons 12 insérés selon la direction Y-Y' dans les trous oblongs 701 et 721 des ailes 70 et 72, et dans les trous oblongs 103a et 105a des rails 10. Lors du montage en force des rails 10 dans les cavaliers 6, les rails 10 sont placés par rapport aux ailes 70 et 72 de telle manière que les trous oblongs 701 et 721 coïncident avec les trous oblongs 103a et 105a de manière à former des croix dont le centre définit des espaces d'insertion des boulons 12 de part et d'autre des ailes 70 et 72. Chaque boulon 12 comporte une tête 121 qui s'appuie sur l'aile 70. Un écrou 14 est vissé sur chaque boulon 12 contre l'aile 72. Les trous oblongs 103a et 105a permettent de compenser les imprécisions dues aux possibles différences de hauteur selon la direction Z-Z' entre les pannes 40. Les trous oblongs 701 et 721 permettent de compenser les imprécisions de montages dues aux éventuelles irrégularités d'espacements des pannes 40 selon la direction X-X' et également aux dilatations longitudinales des rails 10 en cas de fortes chaleurs.To secure the rails 10 to the jumpers 6, the fastening system S comprises bolts 12 inserted in the direction YY 'in the oblong holes 701 and 721 of the wings 70 and 72, and in the oblong holes 103a and 105a of the rails 10. When the mounting of the rails 10 in the jumpers 6, the rails 10 are placed relative to the wings 70 and 72 so that the oblong holes 701 and 721 coincide with the oblong holes 103a and 105a so as to form crosses whose center defines insertion spaces of the bolts 12 on either side of the wings 70 and 72. Each bolt 12 comprises a head 121 which is supported on the flange 70. A nut 14 is screwed onto each bolt 12 against the bolt 12. wing 72. The oblong holes 103a and 105a make it possible to compensate for the inaccuracies due to the possible height differences in the direction ZZ 'between the failures 40. The oblong holes 701 and 721 make it possible to compensate for inaccuracies in mounting due to any irregularities. spacing of the purlins 40 in the direction X-X 'and also longitudinal dilatations of the rails 10 in case of high temperatures.
En outre, la prise en étau des rails 10 entre deux ailes 70 et 72 permet une meilleure répartition de la charge exercée par le poids des rails et des panneaux solaires 2 sur les ailes 70 et 72, contrairement au système décrit dans FR- 2 962 194, dans lequel la charge exercée sur un seul côté d'une seule aile provoque des efforts de flexion pouvant générer des déformations des cavaliers.In addition, the clamping of the rails 10 between two wings 70 and 72 allows a better distribution of the load exerted by the weight of the rails and solar panels 2 on the wings 70 and 72, unlike the system described in FR-2 962 194, in which the load exerted on one side of a single wing causes bending forces that can generate deformations of the riders.
Pour augmenter la résistance mécanique des ailes 70 et 72, celles-ci comprennent des raidisseurs 74 formés par des parties bombées des ailes 70, 72 et de la partie centrale 60. Les raidisseurs 74 s'étendent continûment sur les ailes 70, la partie centrale 60 et les ailes 72. Les parties des raidisseurs 74 qui s'étendent sur les ailes 70 et 72 sont en contact avec les rails 10 et contribuent à la prise en étau des rails 10.To increase the mechanical strength of the wings 70 and 72, these include stiffeners 74 formed by curved portions of the wings 70, 72 and the central portion 60. The stiffeners 74 extend continuously on the wings 70, the central portion 60 and the wings 72. The parts of the stiffeners 74 which extend on the wings 70 and 72 are in contact with the rails 10 and contribute to the grip of the rails 10.
Les cavaliers 6 comprennent également des raidisseurs 76 similaires aux raidisseurs 74 formés par des parties bombées et qui s'étendent continûment sur les supports 62 et 64 et sur les parties centrales 60.The jumpers 6 also comprise stiffeners 76 similar to the stiffeners 74 formed by curved portions and which extend continuously on the supports 62 and 64 and on the central portions 60.
