Abstract

The section according to the invention is arranged in a such a way as to have advantages comparable to those of a symmetrical laminated I-section, while having the advantages of lightness and cost of folded sheet sections. The section (1) comprises a core (3) and two wings (2, 4) which are symmetrical with each other with respect to a median plane (5). Each wing is formed by a flat flange (6) and two lateral edges (7, 9) having substantially the same height. The first edge has a free end (8), while the other (9) is integral with a connecting part (12, 13) of the core. The two connecting parts (12, 13) are approximately parallel and have a mutual separation (B) equal to that (C) of the free ends. This allows the ends of insulation plates to be fitted between the wings (2, 4) of the section on each side of the latter. Separating rods (35) can be fixed to the edges (7, 9) or to the core. Application to the metal structures of buildings. <IMAGE>

Description

La présente invention concerne un profilé autoporteur en tôle pliée pour charpente de bâtiment, comportant une paire d'ailes sensiblement symétriques l'une de l'autre et reliées par une âme ayant une partie centrale plate, chaque aile ayant une semelle perpendiculaire à la partie centrale de l'âme, un premier rebord plié perpendiculairement à la semelle et pourvu d'un bord libre en regard de l'autre aile, et un second rebord plié perpendiculairement à la semelle et raccordé à l'âme par une partie de raccordement de l'âme.The present invention relates to a self-supporting folded sheet metal profile for a building frame, comprising a pair of wings which are substantially symmetrical to one another and connected by a core having a flat central part, each wing having a sole plate perpendicular to the part central of the core, a first flange folded perpendicular to the sole and provided with a free edge facing the other wing, and a second flange folded perpendicular to the sole and connected to the core by a connection part of blade.

L'invention concerne aussi une couverture de bâtiment à charpente métallique comportant des pannes ou lisses parallèles constituées par des profilés tels que mentionnés ci-dessus, des panneaux extérieurs supportés par les pannes ou lisses, ainsi que des plaques isolantes disposées entre lesdits profilés et supportées par eux. L'invention concerne également un procédé de montage d'une telle couverture, dans laquelle lesdits profilés sont fixés sur des poutres métalliques.The invention also relates to a metal frame building covering comprising parallel purlins or beams formed by profiles as mentioned above, external panels supported by the purlins or beams, as well as insulating plates disposed between said profiles and supported by them. The invention also relates to a method of mounting such a cover, in which said sections are fixed to metal beams.

Les profilés en tôles pliées par roulage à froid sont de plus en plus utilisés dans les charpentes métalliques à la place des profilés laminés, notamment parce qu'ils sont beaucoup plus légers et peuvent avoir des profils plus variés. Ils présentent donc d'importants avantages sur le plan du coût et de la facilité de construction. En revanche ils présentent quelques inconvénients par le fait que leur profil transversal ne peut généralement pas être symétrique par rapport à un plan parallèle à l'âme, comme les profilés laminés classiques en I. Cela crée certains problèmes de montage.Cold rolled sheet metal profiles are being used more and more in metal structures instead of laminated profiles, in particular because they are much lighter and can have more varied profiles. They therefore have significant advantages in terms of cost and ease of construction. However, they have some drawbacks in that their transverse profile cannot generally be symmetrical with respect to a plane parallel to the core, like conventional laminated I-sections. This creates certain mounting problems.

Par exemple, le brevet EP-0 110 373 décrit une charpente métallique dont les pannes sont formées par des profilés du genre spécifié plus haut. Chacun desdits seconds rebords des ailes est relié à la partie centrale de l'âme par une partie de raccordement inclinée approximativement à 45°. Avec un tel profil, on peut facilement monter des plaques d'isolation ou de fermeture du côté ouvert du profil et les faire reposer par exemple sur le bord libre de l'aile inférieure, mais ce n'est pas possible de l'autre côté si l'on n'a pas fixé, au dos du profilé, un support spécial pour ces plaques. Il en va de même avec un profilé plié pour pannes, illustré par la figure 3 de la publication WO 85/02639, dans lequel le bord libre de chaque aile se trouve à proximité de l'âme, sur un rabat incliné à 45° en direction de l'âme, symétriquement par rapport à la partie de raccordement de l'âme.For example, patent EP-0 110 373 describes a metal frame whose purlins are formed by profiles of the kind specified above. Each of said second flanges of the wings is connected to the central part of the core by a connection part inclined at approximately 45 °. With such a profile, it is easy to mount insulation or closure plates on the open side of the profile and rest them, for example on the free edge of the lower wing, but this is not possible on the other side. if a special support for these plates has not been fixed on the back of the profile. The same is true with a folded profile for purlins, illustrated by FIG. 3 of the publication WO 85/02639, in which the free edge of each wing is located near the core, on a flap inclined at 45 ° in direction of the core, symmetrically with respect to the connecting part of the core.

La publication FR-A- 2 251 681 décrit un support métallique léger en tôle pliée suivant un profil à double T à ailes plates, pour supporter des panneaux isolants légers qui sont emboîtés entre les deux ailes. Un tel profilé léger ne fait pas partie d'une charpente et il n'est pas utilisable comme panne.The publication FR-A-2 251 681 describes a light metal support made of sheet metal folded along a double T profile with flat wings, for supporting light insulating panels which are nested between the two wings. Such a light profile is not part of a frame and cannot be used as a purlin.

La présente invention a pour but de fournir un profilé et une structure de toiture permettant d'éviter les inconvénients indiqués ci-dessus, grâce à un profil offrant des avantages comparables à ceux d'un profil symétrique en I.The present invention aims to provide a profile and a roof structure to avoid the drawbacks indicated above, thanks to a profile offering advantages comparable to those of a symmetrical I profile.

Dans ce but, l'invention concerne un profilé du genre indiqué plus haut, caractérisé en ce que les parties respectives de raccordement entre les ailes et la partie centrale de l'âme sont sensiblement parallèles et présentent entre elles un écartement qui correspond à l'écartement entre lesdits bords libres des ailes.For this purpose, the invention relates to a profile of the kind indicated above, characterized in that the respective parts of connection between the wings and the central part of the core are substantially parallel and have a spacing between them which corresponds to the spacing between said free edges of the wings.

Un profilé en tôle pliée ayant des parties de raccordement d'âme parallèles l'une à l'autre est illustré par la figure 4 du brevet FR-A-2 151 430. Toutefois il ne s'agit pas d'un profilé autoporteur telle qu'une poutrelle de charpente métallique, mais seulement d'un élément léger de tôlerie, appartenant à un profilé composite et ne pouvant supporter des charges que s'il est couplé rigidement à plusieurs autres éléments analogues appliqués les uns contre les autres. La forme dite "en oméga" de l'âme est seulement destinée à s'emboîter sur une forme correspondante d'un élément parallèle. Il n'y a aucun rapport entre les écartements respectifs des deux bords libres des ailes et des deux parties de raccordement de l'âme. D'après le dessin, ces écartements sont différents.A folded sheet metal profile having core connection parts parallel to each other is illustrated by FIG. 4 of patent FR-A-2 151 430. However, it is not a self-supporting profile such as that a metal structural beam, but only of a light sheet metal element, belonging to a composite profile and can only support loads if it is rigidly coupled to several other similar elements applied against each other. The so-called "omega" shape of the core is only intended to fit onto a corresponding shape of a parallel element. There is no connection between the respective spacings of the two free edges of the wings and of the two connecting parts of the core. According to the drawing, these spacings are different.

Dans une forme de réalisation préférée du profilé selon l'invention, au moins l'un desdits premiers rebords est pourvu de trous pour des éléments écarteurs agencés pour relier deux profilés parallèles. De préférence, au moins l'un desdits seconds rebords est pourvu de trous, disposés en face des trous du premier rebord correspondant.In a preferred embodiment of the profile according to the invention, at least one of said first flanges is provided with holes for spacer elements arranged to connect two parallel profiles. Preferably, at least one of said second flanges is provided with holes, arranged opposite the holes of the first corresponding flange.

La largeur desdites parties de raccordement peut avantageusement être supérieure ou égale à un quart de la largeur des semelles.The width of said connecting parts can advantageously be greater than or equal to a quarter of the width of the flanges.

Une couverture de bâtiment selon l'invention, comportant de tels profilés est caractérisée en ce que les plaques isolantes sont insérées latéralement dans les profilés entre lesdits bords libres des ailes, d'un côté d'un profilé, et entre lesdites parties de raccordement de l'âme de l'autre côté de ce profilé.A building covering according to the invention, comprising such profiles is characterized in that the insulating plates are inserted laterally in the profiles between said free edges of the wings, on one side of a profile, and between said connecting parts of the soul on the other side of this profile.

De préférence, les plaques isolantes ont une épaisseur inférieure à l'écartement entre lesdites parties de raccordement d'un profilé, et un bord d'une plaque isolante se trouvant entre lesdites parties de raccordement est maintenu par engagement entre l'une desdites parties de raccordement et un élément de calage fixé à l'âme du profilé.Preferably, the insulating plates have a thickness less than the spacing between said connection parts of a profile, and an edge of an insulating plate lying between said connection parts is held by engagement between one of said parts of connection and a wedging element fixed to the web of the profile.

Pour le montage d'une telle couverture de bâtiment, la présente invention fournit un procédé caractérisé en ce que, après avoir fixé sur les poutres une série desdits profilés parallèles formant des pannes ou des lisses, on engage un bord d'une première plaque isolante entre les ailes d'un premier profilé, on fait pivoter la plaque autour de ce bord de façon à amener le bord opposé de la plaque près d'un deuxième profilé et l'on engage ce bord entre les ailes du deuxième profilé, et en ce que l'on fixe ensuite des panneaux extérieurs de toiture ou de façade sur lesdits profilés.For the mounting of such a building covering, the present invention provides a method characterized in that, after having fixed on the beams a series of said parallel sections forming purlins or rails, an edge of a first insulating plate is engaged between the wings of a first profile, the plate is pivoted around this edge so as to bring the opposite edge of the plate near a second profile and this edge is engaged between the wings of the second profile, and which is then attached to the exterior roof or facade panels on said profiles.

De préférence, l'on installe des barres d'écartement reliant deux profilés adjacents après la mise en place des plaques isolantes entre ces profilés, lesdites barres étant placées du côté extérieur desdites plaques. On peut fixer les barres d'écartement aux rebords des ailes extérieures des profilés.Preferably, spacers are installed connecting two adjacent profiles after the establishment of the insulating plates between these profiles, said bars being placed on the outside of said plates. The spreader bars can be attached to the edges of the outer wings of the profiles.

La figure 1 représente le profil transversal d'un profilé en tôle galvanisée, pliée par roulage, ayant une forme générale approximativement en C dans laquelle on distingue une aile supérieure 2, une âme 3 et une aile inférieure 4. La forme du profilé 1 est symétrique par rapport à un plan longitudinal médian 5 perpendiculaire à l'âme 3, c'est-à-dire que les ailes 2 et 4 sont symétriques l'une de l'autre. Chaque aile 2, 4 comporte une semelle 6 parallèle au plan 5, un premier rebord 7 perpendiculaire à la semelle 6 et présentant un bord libre 8, et un second rebord 9 également perpendiculaire à la semelle 6, c'est-à-dire que chaque aile définit un canal rectangulaire 10 dans lequel on peut loger certains éléments accessoires tels que des câbles ou des conduites.FIG. 1 represents the transverse profile of a profile made of galvanized sheet metal, folded by rolling, having a general shape approximately in C in which there is a top wing 2, a core 3 and a bottom wing 4. The shape of the profile 1 is symmetrical with respect to a median longitudinal plane 5 perpendicular to the core 3, that is to say that the wings 2 and 4 are symmetrical to one another. Each wing 2, 4 has a sole 6 parallel to the plane 5, a first flange 7 perpendicular to the sole 6 and having a free edge 8, and a second flange 9 also perpendicular to the sole 6, that is to say that each wing defines a rectangular channel 10 in which one can accommodate certain accessory elements such as cables or conduits.

L'âme 3 se compose d'une partie centrale plate 11, perpendiculaire au plan 5, et de deux parties de raccordement 12 et 13 qui la relient respectivement aux ailes 2 et 4. Contrairement au profilé connu mentionné plus haut, les parties de raccordement 12 et 13 du profilé 1 sont pliées sensiblement à angle droit par rapport à la partie centrale 11 de l'âme, de sorte qu'elles définissent entre elles, du côté appelé le dos du profilé, un renfoncement 14 à profil rectangulaire, ayant une profondeur A et une largeur B qui est l'écartement entre les parties 12 et 13.The core 3 consists of a flat central part 11, perpendicular to the plane 5, and two connection parts 12 and 13 which connect it respectively to the wings 2 and 4. Unlike the known profile mentioned above, the connection parts 12 and 13 of the profile 1 are folded substantially at right angles to the central part 11 of the core, so that they define between them, on the side called the back of the profile, a recess 14 with a rectangular profile, having a depth A and a width B which is the spacing between the parts 12 and 13.

Du côté opposé au dos du profilé, les bords libres 8 des deux ailes 2 et 4 présentent un écartement C qui est sensiblement égal à l'écartement B. Ceci présente de grands avantages au point de vue du montage, en particulier pour la mise en place de tous les éléments destinés à être placés entre les ailes 2 et 4 du profilé, car on peut accomplir ces opérations d'une manière aussi aisée qu'avec des profilés laminés classiques en I, ainsi qu'on le décrira plus loin en référence à la figure 4.On the side opposite the back of the profile, the free edges 8 of the two wings 2 and 4 have a spacing C which is substantially equal to the spacing B. This has great advantages from the point of view of mounting, in particular for the installation place of all the elements intended to be placed between the wings 2 and 4 of the profile, because these operations can be carried out as easily as with conventional laminated profiles in I, as will be described later with reference in Figure 4.

La figure 2 montre un autre exemple d'un profilé 16 selon l'invention, ayant une âme de moindre hauteur, mais des ailes 2 et 4 identiques à celles du profilé 1. Dans ce cas aussi, les bords libres 8 des ailes ont un écartement D qui correspond à celui des parties 12 et 13 raccordant les ailes 2 et 4 à la partie centrale 17 de l'âme. Cela permet d'utiliser commodément le profilé 16 pour supporter, sur n'importe lequel de ses côtés, des plaques 18 ayant une épaisseur légèrement inférieure à D. Du côté du dos du profilé, ces plaques sont insérées entre les parties de raccordement 12 et 13 et sont supportées par la partie 13 si l'on suppose que le profilé 16 s'étend horizontalement. De l'autre côté, les plaques 18 sont insérées entre les bords libres 8 et peuvent reposer sur l'un deux. Si le profilé 16 est tourné de 90° dans un sens ou dans l'autre, les plaques 18 peuvent être supportées par la partie centrale 17 de l'âme.FIG. 2 shows another example of a profile 16 according to the invention, having a core of smaller height, but wings 2 and 4 identical to those of profile 1. In this case too, the free edges 8 of the wings have a spacing D which corresponds to that of the parts 12 and 13 connecting the wings 2 and 4 to the central part 17 of the core. This makes it possible to conveniently use the profile 16 to support, on any of its sides, plates 18 having a thickness slightly less than D. On the back side of the profile, these plates are inserted between the connecting parts 12 and 13 and are supported by the part 13 if it is assumed that the section 16 extends horizontally. On the other side, the plates 18 are inserted between the free edges 8 and can rest on one of them. If the profile 16 is rotated 90 ° in one direction or the other, the plates 18 can be supported by the central part 17 of the core.

Le fait que les ailes 2, 4 ont les mêmes dimensions dans les profilés 1 et 16 montre que l'on peut réaliser une gamme de profilés présentant des hauteurs différentes, mais des ailes semblables, ce qui rationalise aussi bien la fabrication des profilés que le montage des structures réalisées avec eux, ainsi que la standardisation d'éléments accessoires utilisables avec ces profilés. De même, on peut prévoir que des profilés de différentes hauteurs ont tous des parties de raccordement 12 et 13 de même largeur c'est-à-dire que la cote A est constante. Toutefois cette condition n'est pas indispensable et l'on peut faire varier la cote A à l'intérieur d'une gamme de profilés, notamment pour adapter les positions du centre de gravité et du centre de torsion, sans perdre les avantages évoqués ci-dessus.The fact that the wings 2, 4 have the same dimensions in the profiles 1 and 16 shows that it is possible to produce a range of profiles having different heights, but similar wings, which rationalizes both the manufacture of the profiles and the erection of structures with them, as well as the standardization of accessory elements that can be used with these profiles. Likewise, provision can be made for profiles of different heights all to have connecting parts 12 and 13 of the same width, that is to say that the dimension A is constant. However, this condition is not essential and the dimension A can be varied within a range of profiles, in particular to adapt the positions of the center of gravity and the center of torsion, without losing the advantages mentioned above. -above.

Un autre aspect avantageux des profilés selon l'invention réside dans la possibilité de prévoir des trous (non représentés) pour des moyens d'assemblage aussi bien dans les rebords 7 et 9 des ailes que dans la partie centrale 11, 17 de l'âme. Le fait que les deux rebords 7 et 9 ont pratiquement la même hauteur permet d'utiliser des moyens d'assemblage identiques. Dans la figure 2, on a indiqué en trait mixte une disposition possible de tubes distanceurs 35 fixés aux rebords 7 et 9 de l'aile supérieure du profilé, au moyen d'embouts 36 de type connu, bloqués dans les extrémités des tubes et fixés dans des trous des rebords 7 et 9.Another advantageous aspect of the profiles according to the invention lies in the possibility of providing holes (not shown) for assembly means both in the flanges 7 and 9 of the wings as in the central part 11, 17 of the core. . The fact that the two flanges 7 and 9 have practically the same height makes it possible to use identical assembly means. In Figure 2, there is indicated in phantom a possible arrangement of distance tubes 35 fixed to the edges 7 and 9 of the upper wing of the profile, by means of end caps 36 of known type, blocked in the ends of the tubes and fixed in holes in flanges 7 and 9.

La figure 3 montre schématiquement un bâtiment tel qu'une halle, comportant une charpente métallique de forme classique, réalisée au moyen de profilés du type décrit ci-dessus. L'ossature du bâtiment comprend des cadres transversaux rigides formés par des poutres 21 à 24 reliées entre elles par des goussets 25 à 27, chacune de ces poutres étant formée, suivant un principe connu dans l'état de la technique, par deux profilés tels que 1 disposés dos à dos et fixés de part et d'autre des goussets. Les éléments 22 et 23 des cadres supportent des pannes métalliques 30 portant des panneaux de couverture 31. Sur les éléments 21 et 24 sont fixées des lisses horizontales 32 portant des panneaux de façade 33.Figure 3 schematically shows a building such as a hall, comprising a metal frame of conventional shape, made by means of profiles of the type described above. The structure of the building comprises rigid transverse frames formed by beams 21 to 24 connected together by gussets 25 to 27, each of these beams being formed, according to a principle known in the prior art, by two profiles such that 1 arranged back to back and fixed on either side of the gussets. The elements 22 and 23 of the frames support metal purlins 30 carrying cover panels 31. On the elements 21 and 24 are fixed horizontal beams 32 carrying front panels 33.

Sur la figure 4, on voit plus en détail les principaux éléments de la toiture comprenant les pannes 30, et les principaux éléments d'une façade comprenant les lisses 32, ces pannes et ces lisses étant formés de profilés en tôle pliée du genre illustré par les figures 1 et 2. Les cadres porteurs ne sont pas représentés, afin de clarifier le dessin.In FIG. 4, the main elements of the roof comprising the purlins 30 are seen in greater detail, and the main elements of a facade comprising the healds 32, these purlins and these healds being formed from folded sheet sections of the kind illustrated by Figures 1 and 2. The frames carriers are not shown, in order to clarify the drawing.

Des plaques rigides d'isolation thermique 34 sont incorporées à la toiture et sont montées sur les ailes inférieures 4 des pannes 30, suivant le principe illustré par la figure 2. Les pannes 30 sont constituées par des profilés relativement hauts, dont l'âme a une hauteur supérieure à deux fois l'épaisseur des plaques 34. Cela permet de disposer, au-dessus de ces plaques, des tubes écarteurs 35 qui sont fixés par des vis centrales dans des trous ménagés à mi-hauteur de l'âme de chaque panne 30, l'extrémité de chaque tube étant en butée contre le profilé d'une manière connue, par l'intermédiaire d'un embout en matière synthétique 36. De même, des plaques verticales d'isolation 37 sont montées entre les lisses 32, ainsi que des tubes distanceurs verticaux 38 fixés de la même manière que les tubes 35. Les tubes 35 et 38 assurent également la retenue des plaques 34 et 37, notamment contre un soulèvement par l'effet du vent.Rigid thermal insulation plates 34 are incorporated into the roof and are mounted on the lower wings 4 of the purlins 30, according to the principle illustrated in FIG. 2. The purlins 30 are formed by relatively high sections, the core of which has a height greater than twice the thickness of the plates 34. This makes it possible to have, above these plates, spacer tubes 35 which are fixed by central screws in holes made at mid-height of the core of each purlin 30, the end of each tube being in abutment against the profile in a known manner, by means of a plastic end piece 36. Likewise, vertical insulation plates 37 are mounted between the rails 32 , as well as vertical distance tubes 38 fixed in the same way as the tubes 35. The tubes 35 and 38 also ensure the retention of the plates 34 and 37, in particular against lifting by the effect of the wind.

Cette construction et la forme particulière des profilés formant les pannes 30 autorisent un mode de montage particulièrement avantageux de la toiture du bâtiment à partir du haut. En effet, une fois que les pannes 30 sont fixées sur les poutres 22 et 23 des cadres transversaux, il est possible de mettre en place les autres éléments de la toiture à partir de passerelles posées directement sur les pannes. Pour le montage des plaques d'isolation 34, on insère le bord inférieur 34a de chaque plaque entre les bords libres des ailes 2 et 4 de la première panne 30, puis on abaisse l'autre bord 34b de la plaque jusqu'à ce qu'il s'appuie sur l'aile inférieure 4 de la deuxième panne 30. On peut alors mettre en place les tubes distanceurs 35 au-dessus de la rangée de plaques 34 ainsi formée, puis les panneaux de couverture 31 qui peuvent être de n'importe quel type usuel. Ensuite, on pratique de même entre les deux pannes suivantes. La mise en place des plaques 34 est très facile et rapide grâce au fait qu'elles reposent directement sur les ailes des pannes 30, sans qu'on doive fixer à celles-ci des supports additionnels pour les plaques. La même méthode est utilisable pour réaliser la façade à partir de l'extérieur. Toutefois, la mise en place des plaques d'isolation 37 peut aussi se faire de l'intérieur, en bénéficiant de la protection de la toiture. Il convient de remarquer que les mêmes profilés formant les pannes 30 et les lisses 32 permettent l'utilisation de plaques d'isolation 34 et 37 plus épaisses que celles qu'on a représenté, sans compliquer la mise en place des tubes distanceurs 35 et 38 car ces tubes, coupés à la longueur voulue, peuvent aussi bien être installés entre les ailes des profilés au lieu d'être fixés aux âmes. Si l'épaisseur des plaques d'isolation est quand même inférieure à l'écartement B ou C (figure 1) des ailes des profilés, ces plaques peuvent être maintenues par des éléments de calage fixés dans des trous ménagés à l'avance dans l'âme de chaque profilé.This construction and the particular shape of the sections forming the purlins 30 allow a particularly advantageous method of mounting the roof of the building from the top. Indeed, once the purlins 30 are fixed on the beams 22 and 23 of the transverse frames, it is possible to set up the other elements of the roof from walkways placed directly on the purlins. For mounting the insulation plates 34, the lower edge 34a of each plate is inserted between the free edges of the wings 2 and 4 of the first purlin 30, then the other edge 34b of the plate is lowered until 'it rests on the lower wing 4 of the second purlin 30. It is then possible to place the distance tubes 35 above the row of plates 34 thus formed, then the cover panels 31 which may be of n any common type. Then, we practice the same between the following two breakdowns. The establishment of the plates 34 is very easy and quick thanks to the fact that they rest directly on the wings of the purlins 30, without it being necessary to fix to them additional supports for the plates. The same method can be used to make the facade from the outside. However, the establishment of the insulation plates 37 can also be done from the inside, while benefiting from the protection of the roof. It should be noted that the same sections forming the purlins 30 and the rails 32 allow the use of insulation plates 34 and 37 thicker than those which have been shown, without complicating the installation of the distance tubes 35 and 38 because these tubes, cut to the desired length, can also be installed between the wings of the profiles instead of being attached to the webs. If the thickness of the insulation plates is still less than the spacing B or C (Figure 1) of the wings of the profiles, these plates can be held by wedging elements fixed in holes made in advance in the soul of each profile.

La présente invention n'est pas limitée aux exemples décrits ci-dessus, mais elle s'étend à toute modification ou variante évidente pour un homme du métier. En particulier, les dimensions et les proportions des différents profils peuvent varier dans une large mesure, sans s'écarter des caractéristiques essentielles de la présente invention.The present invention is not limited to the examples described above, but it extends to any modification or variant obvious to a person skilled in the art. In particular, the dimensions and proportions of the different profiles can vary to a large extent, without departing from the essential characteristics of the present invention.
