Description

L'invention s'inscrit dans le domaine de la construction, et plus particulièrement des plateaux profilés qui sont destinés à être couplés entre eux afin de constituer un système assemblé formant partie d'un bardage. Ces plateaux profilés sont communément dénommés plateaux de bardage.The invention falls within the field of construction, and more particularly profiled trays which are intended to be coupled together in order to constitute an assembled system forming part of a cladding. These profiled trays are commonly referred to as cladding trays.

Les plateaux de bardage profilés, généralement en tôle métallique, assurent la réalisation de parements extérieurs tels que des murs et des toitures.Profiled cladding trays, generally made of sheet metal, ensure the construction of exterior facings such as walls and roofs.

Pour améliorer les performances thermo-acoustique de ces parements, on connait un bardage de type à double peau. La première peau située du côté intérieur de la construction est solidarisée à la structure, par exemple à des poutres verticales. Cette première peau est constituée de plateaux profilés dénommés plateaux de bardage profilés qui sont assemblés entre eux par couturage. La seconde peau située du côté extérieur de la construction est constituée de plateaux profilés dénommés bacs de bardage, qui sont également assemblés entre eux. Une couche d'isolant est interposée entre les deux peaux, assurant l'isolation thermique et acoustique du bardage.To improve the thermo-acoustic performance of these facings, a double-skin type cladding is known. The first skin located on the interior side of the construction is secured to the structure, for example to vertical beams. This first skin consists of profiled trays called profiled cladding trays which are assembled together by stitching. The second skin located on the exterior side of the construction consists of profiled plates called cladding trays, which are also assembled together. A layer of insulation is interposed between the two skins, ensuring the thermal and acoustic insulation of the cladding.

De façon connue, l'isolant est fait d'une pluralité de plaques qui sont insérées et maintenues en position contre les plateaux de bardage. À cet effet, chaque plateau de bardage profilé présente une partie centrale et deux bords pliés opposés destinés à recevoir les plaques d'isolant.In known manner, the insulation is made of a plurality of plates which are inserted and held in position against the cladding plates. To this end, each profiled cladding tray has a central part and two opposite folded edges intended to receive the insulating plates.

L'assemblage de deux plateaux de bardage adjacents sur la structure de la construction s'effectue par le montage du premier plateau de bardage sur la structure, et le montage du second plateau de bardage également sur la structure, de façon que les parties centrales respectives des premier et second plateau de bardage soient en continuité. Le montage du second plateau s'effectue plus précisément par apposition de la face extérieure de l'un de ses bords pliés contre la face extérieure du bord plié proximal du premier plateau de bardage, ces deux bords pliés formant l'interface de couplage entre les deux plateaux. L'opération est répétée pour la mise en place de tous les plateaux de bardage. L'étanchéité à l'air au niveau des interfaces de couplage peut être assurée par l'interposition d'un joint d'étanchéité. Le joint d'étanchéité est collé manuellement sur chantier sur la face extérieure du bord plié du premier plateau de bardage venant d'être installé, juste avant que le plateau de bardage adjacent ne soit lui-même installé et son bord plié dédié apposé contre le bord plié du premier plateau muni du joint d'étanchéité.The assembly of two adjacent cladding plates on the structure of the construction is carried out by mounting the first cladding plate on the structure, and the mounting of the second cladding plate also on the structure, so that the respective central parts first and second cladding trays are continuous. The assembly of the second plate is carried out more precisely by affixing the outer face of one of its folded edges against the outer face of the proximal folded edge of the first cladding plate, these two folded edges forming the coupling interface between the two plates. The operation is repeated for the installation of all the cladding trays. The airtightness at the level of the coupling interfaces can be ensured by the interposition of a seal. The seal is glued manually on site to the exterior face of the folded edge of the first cladding plate that has just been installed, just before the adjacent cladding plate is itself installed and its dedicated folded edge affixed against the folded edge of the first tray fitted with the sealing gasket.

Cette étape de collage manuel sur le lieu de l'installation augmente notablement la durée de l'installation et peut induire une surconsommation de joint d'étanchéité du fait que sa réalisation à la main sans guidage provoque de nombreuses non linéarités. En outre, ce collage étant réalisé à la main, son homogénéité n'est pas garantie, et donc des défauts d'étanchéité peuvent apparaître dans des petites portions où le collage est inexistant ou imparfait. Il est connu de DE10341635 un plateau de bardage comportant un joint d'étanchéité expansible pouvant être maintenu dans un état compressé par un panneau adjacent.This manual gluing step on the installation site significantly increases the duration of the installation and can induce overconsumption of the seal due to the fact that its realization by hand without guidance causes many non-linearities. In addition, this bonding being carried out by hand, its homogeneity is not guaranteed, and therefore sealing defects may appear in small portions where the bonding is non-existent or imperfect. It is known from DE10341635 a cladding tray having an expandable gasket that can be maintained in a compressed state by an adjacent panel.

Sur les figures 1 à 3, la direction X est une direction dite longitudinale du plateau profilé 1j de l'invention, la direction Y est une direction dite transversale du plateau profilé 1j, laquelle est perpendiculaire à la direction longitudinale X, et la direction Z est une direction dite verticale du plateau profilé 1j, laquelle est perpendiculaire aux directions longitudinale X et transversale Y.On the figures 1 to 3 , the X direction is a so-called longitudinal direction of the profile plate 1 j of the invention, the Y direction is a so-called transverse direction of the profile plate 1 j , which is perpendicular to the longitudinal direction X, and the Z direction is a so-called direction vertical of the profiled plate 1 j , which is perpendicular to the longitudinal X and transverse Y directions.

On a schématiquement représenté sur les figures 1 à 3 un exemple de réalisation d'un plateau profilé 1j selon l'invention.Schematically represented on the figures 1 to 3 an embodiment of a profiled tray 1 j according to the invention.

Comme illustré, un plateau de bardage de l'invention 1j de profil prédéfini obtenu par découpe et profilage présente une forme générale en U, avec une partie centrale 5 présentant une pluralité de nervures longitudinales parallèles de rigidification non référencées, et deux bords opposés longitudinaux 6 et 7 qui sont pliés autour de deux premières lignes de pliage longitudinales 6a,7a. De préférence, les premier 6 et second 7 bords pliés sont sensiblement perpendiculaires à la partie centrale 5. Chaque bord plié 6,7 s'étend transversalement depuis la ligne de pliage associée 6a,7a jusqu'à une bordure 8, 9 elle-même pliée autour d'une seconde ligne de pliage longitudinale 6b,7b. Dans ce mode de réalisation, les deux bordures 8,9 sont pliées dans le même sens et parallèles à la partie centrale 5, de sorte que la bordure 8 du premier bord plié 6 est dirigée vers l'extérieur du plateau 1j, tandis que la bordure 9 du second bord plié 7 est dirigée vers l'intérieur du plateau 1j. Le plateau de bardage de l'invention s'applique également à d'autres configurations et directions de pliage de ces bordures 8,9, par exemple à un plateau de bardage pour lequel les bordures 8 et 9 sont dirigées toutes les deux vers l'extérieur du plateau 1j.As illustrated, a cladding plate of the invention 1 j of predefined profile obtained by cutting and profiling has a general U-shape, with a central part 5 having a plurality of parallel longitudinal ribs of non-referenced stiffening, and two opposite longitudinal edges 6 and 7 which are folded around two first longitudinal fold lines 6a, 7a. Preferably, the first 6 and second 7 folded edges are substantially perpendicular to the central part 5. Each folded edge 6,7 extends transversely from the associated folding line 6a,7a to a border 8,9 itself folded around a second longitudinal fold line 6b, 7b. In this embodiment, the two edges 8.9 are folded in the same direction and parallel to the central part 5, so that the edge 8 of the first folded edge 6 is directed towards the outside of the plate 1 j , while the edge 9 of the second folded edge 7 is directed towards the inside of the tray 1 j . The cladding plate of the invention also applies to other configurations and folding directions of these borders 8, 9, for example to a cladding plate for which the borders 8 and 9 are both directed towards the outside the plateau 1 d .

Chaque bord plié 6,7 présente une face extérieure longitudinale 3,4, c'est-à-dire tournée vers l'extérieur du plateau de bardage 1j. En référence à la figure 5, chaque face extérieure 3,4 est destiné à être installée en regard de la face extérieure 3,4 d'un bord plié 6,7 d'un plateau de bardage 11, 12 adjacent afin de participer à un système assemblé formant parement 2 (figure 4).Each folded edge 6.7 has a longitudinal outer face 3.4, that is to say facing the outside of the siding plate 1 j . With reference to the figure 5 , each outer face 3.4 is intended to be installed opposite the outer face 3.4 of a folded edge 6.7 of a cladding plate 1 1 , 1 2 adjacent in order to participate in an assembled system forming a facing 2 ( figure 4 ).

Comme visible sur la figure 2, chaque bord plié 6,7 présente en outre dans ce mode de réalisation une nervure de rigidification 6c dirigée vers la partie centrale 5 du plateau de bardage 1j.As seen on the picture 2 , each bent edge 6.7 further has in this embodiment a stiffening rib 6c directed towards the central part 5 of the cladding plate 1d .

Selon l'invention, le plateau de bardage profilé 1j comprend un joint d'étanchéité expansible 10 qui est solidarisé au plateau de bardage 1j préalablement à son arrivée sur le chantier. On entend par joint expansible un joint dont la structure interne comprend de l'air et qui est apte à se présenter sous forme compressé lorsqu'on lui applique une force de pression, et sous une forme dilatée ou expansée lorsqu'il est soumis à aucune force de pression et qu'il est en contact avec de l'air. Le joint 10 est disposé sur tout ou partie de la longueur de la face extérieure 3,4 de l'un des bords opposés pliés 6,7, de préférence sur toute sa longueur. Ce joint 10 permet d'assurer l'étanchéité à l'air de l'assemblage des plateaux de bardage 1j montés sur la structure d'une construction lors de l'élaboration d'un bardage comme décrit en introduction.According to the invention, the profiled cladding plate 1 j comprises an expandable seal 10 which is secured to the cladding plate 1 j prior to its arrival on the site. The term “expandable seal” means a seal whose internal structure comprises air and which is capable of being in a compressed form when a pressure force is applied to it, and in a dilated or expanded form when it is subjected to any pressure force and that it is in contact with air. The gasket 10 is arranged over all or part of the length of the outer face 3.4 of one of the opposite folded edges 6.7, preferably over its entire length. This joint 10 makes it possible to ensure the airtightness of the assembly of the cladding trays 1 d mounted on the structure of a construction during the development of a cladding as described in the introduction.

Pour assurer cette étanchéité à l'air entre deux plateaux adjacents 1j, le joint 10 peut être disposé à tout niveau de la face extérieure 3,4 du bord considéré 6,7 depuis la première ligne de pliage 6a,7a jusqu'à la bordure 8,9. Néanmoins, dans le cas où la face extérieure 3,4 présente une hétérogénéité de rigidité, on préfère disposer le joint 10 à un niveau de la face extérieure 3,4 qui présente la plus grande rigidité de façon à éviter tout décalage de positionnement du joint 10 lors de l'assemblage des plateaux de bardage 1j. Le joint 10 peut par ailleurs être indifféremment disposé sur l'une ou l'autre des faces extérieures 3,4 des bords pliés 6,7 si le procédé de mise en forme du plateau de bardage 1j n'entraîne pas d'endommagement conséquent du joint 10.To ensure this airtightness between two adjacent plates 1 j , the seal 10 can be arranged at any level of the outer face 3.4 of the edge considered 6.7 from the first fold line 6a, 7a to the border 8.9. Nevertheless, in the case where the outer face 3.4 has a heterogeneity of rigidity, it is preferred to arrange the seal 10 at a level of the outer face 3.4 which has the greatest rigidity so as to avoid any positioning offset of the seal. 10 when assembling the siding trays 1 d . The seal 10 can also be placed on one or the other of the outer faces 3.4 of the folded edges 6.7 if the process for shaping the cladding plate 1 j does not cause any substantial damage. of seal 10.

Dans le mode de réalisation illustré sur les figures 1 à 5, les galets de profilage utilisés lors de la mise en forme du plateau de bardage 1j sont conformés, du côté du bord 7 plié vers l'intérieur, de façon à venir en contact avec la face extérieure 4 de ce bord plié 7. A l'inverse, les galets situés du côté du bord 6 plié vers l'extérieur assurent une absence de contact avec la face extérieure concernée 3 et ce, pour toutes les passes du profilage. C'est la raison pour laquelle le joint 10 est disposé, dans ce mode de réalisation, sur la face extérieure 3 du bord 6 plié vers l'extérieur. En outre, la bordure 8 et la partie inférieure de la face 3 située sous la nervure 6c présentent une rigidité insuffisante pour assurer le positionnement contrôlé du joint 10 relativement à un plateau de bardage adjacente 1j lors de l'assemblage de ces plateaux 1j. La nervure 6c ne constitue pas non plus une position idéale de réception du joint 10 en raison de difficulté de positionnement de ce joint 10. Il s'ensuit que dans ce mode de réalisation, le joint 10 est positionné sur la face extérieure 3 du bord 6 plié vers l'extérieur entre la nervure 6c et la première ligne de pliage 6a. De façon plus générale et indépendamment de la nervure 6c, le joint 10 est positionné à proximité de la première ligne de pliage 6a, c'est-à-dire à moins de 10 millimètres de cette première ligne de pliage 6a. Ce positionnement à proximité de la première ligne de pliage est également avantageux en raison de sa proximité avec un joint d'appui appliqué sur les poutres de la structure sur lesquels sont montés les panneaux de bardage (le joint d'appui est référencé 15 sur la figure 4). Cette proximité entre le joint d'étanchéité 10 et le joint d'appui 15 confère une étanchéité améliorée du bardage.In the embodiment illustrated in the figures 1 to 5 , the profiling rollers used when shaping the cladding plate 1 j are shaped, on the side of the edge 7 folded inwards, so as to come into contact with the outer face 4 of this folded edge 7. A Conversely, the rollers located on the side of the edge 6 bent outwards ensure an absence of contact with the outer face concerned 3 and this, for all the profiling passes. This is the reason why the seal 10 is arranged, in this embodiment, on the outer face 3 of the edge 6 bent outwards. In addition, the border 8 and the lower part of the face 3 located under the rib 6c have insufficient rigidity to ensure the controlled positioning of the seal 10 relative to an adjacent cladding plate 1 d during the assembly of these plates 1 d . The rib 6c does not constitute either an ideal position for receiving the seal 10 due to the difficulty of positioning this seal 10. It follows that in this embodiment, the seal 10 is positioned on the outer face 3 of the edge 6 bent outward between the rib 6c and the first fold line 6a. More generally and independently of the rib 6c, the seal 10 is positioned close to the first fold line 6a, that is to say less than 10 millimeters from this first fold line 6a. This positioning close to the first bend line is also advantageous due to its proximity to a joint. bearing applied to the beams of the structure on which the cladding panels are mounted (the bearing joint is referenced 15 on the figure 4 ). This proximity between the seal 10 and the bearing seal 15 provides improved sealing of the cladding.

Le joint 10 ainsi positionné comporte une face arrière 11 et une face avant opposée 12. La face arrière 11 est solidarisée par collage sur cette partie de la face extérieure longitudinale 3 du premier bord plié 6. La face avant 12 est protégée et recouverte intégralement par un film de compression adhésif 13 qui empêche l'expansion du joint d'étanchéité expansible 10 et le maintient donc dans un état compressé jusqu'à son retrait (illustré sur la figure 3) juste avant l'installation de la première face 3 en regard de la seconde face 4 d'un plateau profilé adjacent pour la réalisation d'un parement 2.The seal 10 thus positioned comprises a rear face 11 and an opposite front face 12. The rear face 11 is secured by gluing on this part of the longitudinal outer face 3 of the first folded edge 6. The front face 12 is protected and completely covered by an adhesive compression film 13 which prevents the expansion of the expandable gasket 10 and therefore maintains it in a compressed state until it is removed (shown in the picture 3 ) just before the installation of the first face 3 facing the second face 4 of an adjacent profiled plate for the production of a facing 2.

En référence à la figure 2, pour maintenir dans un état compressé le joint d'étanchéité expansible 10, le film de compression 13 est tendu sur et contre la face avant 12 du joint d'étanchéité 10 (pour des raisons d'identification des différents éléments, le film de compression 13 est représenté sur la figure 2 sensiblement à distance du joint 10). Pour ce faire, le film de compression 13 présente une largeur substantiellement supérieure à celle du joint d'étanchéité 10, et une couche adhésive qui assure sa solidarisation par adhésion au plateau de part et d'autre du joint d'étanchéité 10 depuis la périphérie de la partie centrale 5 jusqu'à la nervure de rigidification 6c, ce qui représente par exemple une largeur comprise entre 50 et 60 millimètres.With reference to the picture 2 , to maintain the expandable seal 10 in a compressed state, the compression film 13 is stretched over and against the front face 12 of the seal 10 (for reasons of identification of the various elements, the compression film 13 is shown on the picture 2 substantially at a distance from the seal 10). To do this, the compression film 13 has a width substantially greater than that of the seal 10, and an adhesive layer which ensures its attachment by adhesion to the plate on either side of the seal 10 from the periphery. from the central part 5 to the stiffening rib 6c, which represents for example a width of between 50 and 60 millimeters.

On définit un rapport minimum Rmin entre la largeur du film de compression 13 et la largeur du joint 10 à partir duquel le maintien du joint 10 dans un état compressé par le film 13 est amélioré.. Ce rapport minimum Rmin peut être évalué à 3. Dans le mode de réalisation représenté sur la figure 2, le rapport R entre la largeur du film de compression 13 et la largeur du joint 10 est de 4, ce qui garanti le maintien sécurisé du joint 10 dans son état compressé.A minimum ratio Rmin is defined between the width of the compression film 13 and the width of the seal 10 from which the maintenance of the seal 10 in a state compressed by the film 13 is improved. This minimum ratio Rmin can be evaluated at 3. In the embodiment shown in the figure 2 , the ratio R between the width of the compression film 13 and the width of the seal 10 is 4, which guarantees the secure maintenance of the seal 10 in its compressed state.

Selon les besoins applicatifs, le joint d'étanchéité expansible 10 pourra, par exemple, présenter une largeur comprise entre 10 et 30 millimètres, une épaisseur comprise entre 1 mm et 3 mm lorsqu'il est comprimé (et donc recouvert du film de compression 13), et une épaisseur comprise entre 10 mm et 15 mm lorsqu'il est expansé (une fois le film de compression 13 retiré). Le film de compression 13 pourra quant à lui présenter une largeur comprise entre 30 et 120 millimètres.Depending on the application needs, the expandable seal 10 may, for example, have a width of between 10 and 30 millimeters, a thickness between 1 mm and 3 mm when it is compressed (and therefore covered with the compression film 13), and a thickness between 10 mm and 15 mm when it is expanded (once the compression film 13 has been removed). The compression film 13 may for its part have a width of between 30 and 120 millimeters.

Le joint d'étanchéité expansible 10 peut être réalisé en mousse de polyuréthane à cellules semi-ouvertes et imprégnée à cœur d'un mélange stable de résines synthétiques. A cet effet, on pourra, par exemple, utiliser le joint d'étanchéité expansible 10 qui est fabriqué par la société ISO-Chemie et appelé ISO-MEMBRA SX®. Le film de compression 13 peut être quant à lui être réalisé en polyéthylène.The expandable seal 10 can be made of polyurethane foam with semi-open cells and impregnated to the core with a stable mixture of synthetic resins. For this purpose, it is possible, for example, to use the expandable seal 10 which is manufactured by the company ISO-Chemie and called ISO-MEMBRA SX ® . The compression film 13 can itself be made of polyethylene.

On notera qu'il est avantageux que la face arrière 11 du joint d'étanchéité expansible 10 soit munie d'une couche adhésive afin de permettre son collage sur la face extérieure 3 du bord plié 6 par simple plaquage. En d'autres termes, il est avantageux que cette face arrière 11 soit autocollante pour ne pas avoir à réaliser un encollage de la zone sur laquelle est appliquée le joint d'étanchéité 10.It will be noted that it is advantageous for the rear face 11 of the expandable seal 10 to be provided with an adhesive layer in order to allow it to be bonded to the outer face 3 of the folded edge 6 by simple pressing. In other words, it is advantageous for this rear face 11 to be self-adhesive so as not to have to glue the area to which the seal 10 is applied.

Il est également avantageux que la face avant 12 du joint d'étanchéité expansible 10 soit munie d'une couche adhésive afin de permettre son collage automatique au plateau de bardage adjacent mais également pour renforcer le maintien du film de compression 13 sur le joint d'étanchéité 10 avant l'arrivée sur chantier.It is also advantageous for the front face 12 of the expandable seal 10 to be provided with an adhesive layer in order to allow it to be automatically bonded to the adjacent cladding plate but also to reinforce the hold of the compression film 13 on the seal. waterproofing 10 before arriving on site.

Dans cette variante, la face extérieure de la partie centrale 5 du plateau de bardage 1j est recouverte d'un film de protection F usuellement utilisé pour protéger cette partie centrale avant l'installation du plateau de bardage 1j sur chantier. Comme illustré sur la figure 2, le bord périphérique du film F est recouvert par le film de compression 13 qui est apposé sur le plateau de bardage 1j après le film de protection F. Au regard de la présence du joint 10 et du film de compression 13 tel que précédemment décrit, il est préférable que le bord périphérique du film F ne déborde pas du côté de la face extérieure 3 du bord plié 6.In this variant, the outer face of the central part 5 of the cladding plate 1 j is covered with a protective film F usually used to protect this central part before the installation of the cladding plate 1 j on site. As illustrated on the picture 2 , the peripheral edge of the film F is covered by the compression film 13 which is affixed to the cladding plate 1 day after the protective film F. With regard to the presence of the seal 10 and the compression film 13 as previously described , it is preferable that the peripheral edge of the film F does not overflow on the side of the outer face 3 of the folded edge 6.

En référence à la figure 9, le maintien du joint d'étanchéité 10 dans un état compressé peut en outre être sécurisé par le colisage des plateaux de bardage 1j de l'invention. À cet effet, l'assemblage pour colisage peut être réalisé de façon que le joint d'étanchéité compressé 10 soit maintenu en appui de contact surfacique avec un plateau adjacent 1j+1. Comme illustré sur la figure 9, l'assemblage pour colisage de l'invention prévoit le maintien en appui de contact surfacique de la face extérieure 3 du bord plié associé 6 d'un premier plateau 11, laquelle face extérieure 3 comporte le joint compressé 10 et le film de compression 13, contre la face extérieure 4 du bord plié associé 7 du plateau adjacent 12. L'assemblage pour colisage arrive sur chantier et chaque plateau profilé 1j est prêt à être couplé à un autre plateau profilé 1j sans qu'il faille mettre en place sur chantier le joint d'étanchéité, puisque ce dernier est déjà présent sous la forme du joint d'étanchéité expansible 10 toujours sous forme compressé.With reference to the figure 9 , maintaining the seal 10 in a compressed state can also be secured by packing the cladding trays 1 j of the invention. To this end, the assembly for packing can be made so that the compressed seal 10 is held in surface contact support with an adjacent plate 1 d+1 . As illustrated on the figure 9 , the assembly for packaging of the invention provides for the maintenance in support of surface contact of the outer face 3 of the associated folded edge 6 of a first plate 1 1 , which outer face 3 comprises the compressed seal 10 and the compression film 13, against the outer face 4 of the associated folded edge 7 of the adjacent plate 12 . The assembly for packing arrives on site and each profiled plate 1 j is ready to be coupled to another profiled plate 1 j without it being necessary to set up the sealing joint on site, since the latter is already present under the shape of the expandable seal 10 still in compressed form.

En référence aux figures 4 et 5, la réalisation du bardage (ou parement) 2 s'effectue généralement du bas vers le haut en installant les plateaux de bardage profilés les plus bas 11 par solidarisation de ces plateaux 11 à des poutres verticales 14 régulièrement réparties selon l'axe X le long de la construction et comportant chacun un joint d'appui 15 également vertical qui participe à l'étanchéité à l'air du bardage 2 et contre lequel les plateaux de bardages 11, 12, 13 viennent en appui. Comme précédemment indiqué, la proximité entre le joint d'appui 15 et les joints d'étanchéité 10 améliore les performances générales d'étanchéité du bardage. Une fois les plateaux de bardage inférieurs 11 installés, on retire le film de compression 13 disposé sur le bord plié 6 des plateaux de bardages 12 destinés à être disposés au-dessus des plateaux de bardage inférieurs 11. L"expansion du joint d'étanchéité 10 concerné peut commencer. On peut alors coupler les deux plateaux de bardage 11, 12 en accolant le premier bord plié 6 du deuxième plateau de bardage 12 au second bord plié 7 du plateau de bardage inférieur 11 situé juste au-dessous. Le joint d'étanchéité expansible 10 du plateau de bardage profilé 12 continue son expansion en étant interposé entre les faces extérieures 3,4 respectives desdits deux bords pliés 3,4. L'opération se répète avec les troisièmes plateaux profilés 13 ainsi que les plateaux de bardages supérieurs non représentés et ce, sur toute la longueur du bardage (longueur considérée selon l'axe X). Des plaques d'isolants 16 sont ensuite disposées contre les panneaux de bardages 11, 12, 13, chaque plaque d'isolant 16 étant insérée par glissement entre les bords pliés 6,7 du panneau de bardage considéré. Une fois les plaques d'isolant 17 installées, des bacs de bardage 17 constituant la seconde peau du bardage 2 sont montés au niveau de la face libre des plaques d'isolants 16 par des moyens connus. Le bardage 2 peut alternativement comporter des écarteurs non représentés sur lesquels sont fixés les bacs de bardage 17. On constitue ainsi progressivement un bardage 2 du type de celui partiellement illustré sur la figure 4.With reference to figure 4 and 5 , the realization of the cladding (or facing) 2 is generally carried out from the bottom upwards by installing the lowest profiled cladding plates 1 1 by joining these plates 1 1 to vertical beams 14 regularly distributed along the axis X along the construction and each comprising a bearing seal 15, also vertical, which contributes to the airtightness of the cladding 2 and against which the cladding plates 1 1 , 1 2 , 1 3 bear. As previously indicated, the proximity between the bearing seal 15 and the seals 10 improves the general sealing performance of the cladding. Once the lower cladding plates 11 have been installed, the compression film 13 disposed on the folded edge 6 of the cladding plates 12 intended to be placed above the lower cladding plates 11 is removed. The expansion of the seal 10 concerned can begin. The two cladding plates 1 1 , 1 2 can then be coupled by joining the first folded edge 6 of the second cladding plate 1 2 to the second folded edge 7 of the cladding plate bottom 11 located just below.The expandable seal 10 of the profiled cladding plate 12 continues its expansion by being interposed between the respective outer faces 3.4 of said two folded edges 3.4. The operation is repeated with the third profiled plates 1 3 as well as the upper cladding plates not shown and this, over the entire length of the cladding (length considered along the X axis). Insulating plates 16 are then placed against the cladding panels 11 , 12 , 13 , each insulating plate 16 being inserted by sliding between the folded edges 6.7 of the cladding panel in question. Once the insulating plates 17 have been installed, cladding trays 17 constituting the second skin of the cladding 2 are mounted at the level of the free face of the insulating plates 16 by known means. The cladding 2 may alternatively comprise spacers, not shown, on which the cladding trays 17 are fixed. A cladding 2 of the type partially illustrated on the figure 4 .

Selon l'invention et en référence aux figures 6 à 8, pour réaliser un plateau profilé 1j, on peut mettre en œuvre un procédé de réalisation automatisé, dans une installation industrielle dédiée 16.According to the invention and with reference to figures 6 to 8 , to make a profiled plate 1 j , an automated production process can be implemented, in a dedicated industrial installation 16.

Ce procédé comprend une étape dans laquelle on commence par débobiner (étape 100 de la figure 6) sensiblement à plat une tôle d'acier 15 préalablement bobinée. La tôle d'acier peut être en acier prélaqué ou galvanisé passivé ou revêtu d'un vernis . Cette tôle 15, déroulée sensiblement à plat, est déplacée par un convoyeur. On applique alors de façon automatisée sur une partie au moins d'une zone 14 de la tôle débobinée 15, qui s'étend suivant la direction longitudinale X, la face arrière 11 du joint d'étanchéité expansible 10 (étape 110 de la figure 6), et on recouvre quasi concomitamment la face avant 12 du joint 10 par le film de compression 13 qui empêche l'expansion du joint d'étanchéité expansible 10 (étape 110 de la figure 6). On procède alors au découpage de la tôle 15 et à sa mise en forme (étape 130 de la figure 6) pour obtenir le plateau de bardage profilé de l'invention préalablement décrit.This method includes a step in which one begins by unwinding (step 100 of the figure 6 ) substantially flat a steel sheet 15 previously coiled. The steel sheet can be pre-painted or galvanized steel, passivated or coated with a varnish. This sheet 15, unrolled substantially flat, is moved by a conveyor. Then applied in an automated manner to at least part of an area 14 of the uncoiled sheet 15, which extends along the longitudinal direction X, the rear face 11 of the expandable seal 10 (step 110 of the figure 6 ), and the front face 12 of the seal 10 is almost simultaneously covered by the compression film 13 which prevents the expansion of the expandable seal 10 (step 110 of the figure 6 ). One then proceeds to the cutting of the sheet 15 and to its shaping (step 130 of the figure 6 ) to obtain the profiled cladding tray of the invention previously described.

En référence aux figures 7 et 8, l'étape d'application du joint d'étanchéité 10 sur la tôle 15 en mouvement est réalisé par débobinage continu du joint d'étanchéité expansible 10 d'une bobine 17 installée au-dessus de la tôle 15, en même temps que l'on plaque de façon continue contre la zone 14 de la tôle 15 une partie précédemment déroulée du joint d'étanchéité expansible 10 en collant sa face arrière 11 sur cette zone 14. Le joint d'étanchéité expansible 10 est appliqué contre la zone 14 au moyen de deux cylindres 20a,20b qui sont en rotation libre, au moins dans le sens inverse de la direction de convoyage. Le premier cylindre 20a comporte une rainure 20a1 qui assure le guidage rectiligne du joint 10 sur la tôle 15. Le second cylindre 20b disposé en aval du premier cylindre 20a comporte quant à lui une surface plane non rainurée pour assurer le plaquage et le collage du joint 10 contre la zone 14 de la tôle d'acier 15. Les cylindres 20a, 20b peuvent, par exemple et comme illustré, être placés au-dessus et contre un cylindre de convoyage 21 de l'installation industrielle 16 sur lequel se déplace la tôle d'acier 15.With reference to figures 7 and 8 , the step of applying the sealing gasket 10 to the moving sheet 15 is carried out by continuously unwinding the expandable sealing gasket 10 from a coil 17 installed above the sheet 15, at the same time as the a previously unrolled part of the expandable seal 10 is continuously pressed against the zone 14 of the sheet 15 by bonding its rear face 11 to this zone 14. The expandable seal 10 is applied against the zone 14 at the means of two cylinders 20a, 20b which are in free rotation, at least in the opposite direction to the conveying direction. The first cylinder 20a comprises a groove 20a1 which ensures the rectilinear guidance of the gasket 10 on the sheet 15. The second cylinder 20b disposed downstream of the first cylinder 20a comprises for its part a non-grooved flat surface to ensure the plating and the bonding of the gasket 10 against the zone 14 of the steel sheet 15. The cylinders 20a, 20b can, for example and as illustrated, be placed above and against a conveying cylinder 21 of the industrial installation 16 on which the sheet moves of steel 15.

Si le joint d'étanchéité expansible 10 comporte un film 18 protégeant sa face arrière 11, ce film 18 est retiré automatiquement par des moyens appropriés non représentés au fur et à mesure que le joint d'étanchéité expansible 10 est déroulé de la bobine 17 et collé sur la zone 14.If the expandable seal 10 includes a film 18 protecting its rear face 11, this film 18 is automatically removed by appropriate means, not shown, as the expandable seal 10 is unwound from the reel 17 and pasted on area 14.

De préférence, et comme décrit précédemment, il est préférable d'utiliser un joint d'étanchéité expansible 10 ayant une face arrière 11 munie d'une couche adhésive afin de permettre son collage automatique à la zone 14 de façon continue. En l'absence de cette couche adhésive, on doit procéder à un encollage de la zone 14.Preferably, and as described above, it is preferable to use an expandable seal 10 having a rear face 11 provided with an adhesive layer in order to allow its automatic bonding to the zone 14 in a continuous manner. In the absence of this adhesive layer, area 14 must be glued.

L'application du film de compression 13 est réalisé rapidement ou quasi concomitamment à l'application du joint d'étanchéité 10 afin d'éviter l'expansion du joint 10. A cet effet, comme illustré sur les figures 7 et 8, après avoir collé le joint d'étanchéité expansible 10 sur la zone 14 de la tôle d'acier 15, le film de compression 13 est appliqué sur la face avant 12 de ce joint d'étanchéité 10 et sur la tôle d'acier de part et d'autre du joint 10 pour des raisons expliquées précédemment. Pour ce faire, le film de compression 13 est initialement enroulé sur une autre bobine 19 qui est installée au-dessus de la tôle d'acier en mouvement 15, en aval du cylindre 20 d'application du joint 10. Le film de compression 13 est alors déroulé de façon continue par des moyens appropriés et plaqué sur la zone 14 de la tôle d'acier 15 contre le joint d'étanchéité expansible 10 par un cylindre non représenté. Les opérations de déroulement du joint 10 de sa bobine dédiée 17 et de recouvrement du joint 10 par le film de compression 13 sont réalisés en un laps de temps suffisamment court pour éviter l'expansion du joint 10. À cet effet, le film de compression 13 est de préférence appliqué sur le joint 10 moins de 30 secondes après l'application de ce joint 10 sur la zone 14 de la tôle d'acier 15.The application of the compression film 13 is carried out quickly or almost simultaneously with the application of the seal 10 in order to avoid the expansion of the seal 10. For this purpose, as illustrated in the figures 7 and 8 , after having bonded the expandable seal 10 to the zone 14 of the steel sheet 15, the compression film 13 is applied to the front face 12 of this seal 10 and to the steel sheet of either side of seal 10 for reasons explained above. To do this, the compression film 13 is initially wound on another reel 19 which is installed above the moving steel sheet 15, downstream of the cylinder 20 for applying the gasket 10. The compression film 13 is then unrolled continuously by appropriate means and pressed against the zone 14 of the steel sheet 15 against the expandable seal 10 by a cylinder, not shown. The operations of unwinding the seal 10 from its dedicated reel 17 and covering the seal 10 with the compression film 13 are carried out in a sufficiently short period of time to avoid the expansion of the seal 10. For this purpose, the compression film 13 is preferably applied to the seal 10 less than 30 seconds after the application of this seal 10 to the area 14 of the steel sheet 15.

La tôle d'acier 15 comportant le joint d'étanchéité 10 et le film de compression est découpée à longueur avant sa mise en forme par profilage. Cette découpe préalable permet d'éviter l'endommagement du joint 10 si la découpe était réalisée après le profilage. Le profilage de la tôle d'acier peut être réalisé par un train de galets de profilage (non représentés) qui n'entrent pas en contact avec le joint d'étanchéité expansible 10 collé et le film de compression 13 pour éviter de l'endommager, comme expliqué précédemment.The steel sheet 15 comprising the seal 10 and the compression film is cut to length before it is shaped by profiling. This preliminary cutting makes it possible to avoid damaging the gasket 10 if the cutting was carried out after profiling. The profiling of the steel sheet can be carried out by a train of profiling rollers (not shown) which do not come into contact with the glued expandable seal 10 and the compression film 13 to avoid damaging it. , as explained above.

On comprend que la pose du joint 10 sur la tôle d'acier 15 est préférentiellement réalisée sur la tôle plane 15 avant sa mise en forme pour faciliter cette pose et permettre un positionnement précis du joint 10 et du film de compression 13. Grâce au procédé selon l'invention, le joint d'étanchéité expansible 10 peut être collé de façon précise suivant la direction longitudinale X de la tôle d'acier 15 et du plateau de bardage profilé 1. Son application est rectiligne, ce qui évite sa surconsommation. Et son application ainsi automatisée et précise réduit substantiellement les risques de défauts d'étanchéité dans le parement 2 réalisé au moyen d'une pluralités de plateaux de bardage de l'invention.It is understood that the laying of the seal 10 on the steel sheet 15 is preferably carried out on the flat sheet 15 before its shaping to facilitate this laying and allow precise positioning of the seal 10 and of the compression film 13. Thanks to the process according to the invention, the expandable seal 10 can be bonded precisely along the longitudinal direction X of the steel sheet 15 and of the profiled cladding plate 1. Its application is rectilinear, which avoids its overconsumption. And its application thus automated and precise substantially reduces the risk of leaks in the facing 2 produced by means of a plurality of cladding trays of the invention.
