Description
Panneaux autoportants, emboîtables et étanches, pour la formation de
couverture.Self-supporting, nestable and waterproof panels for the formation of
blanket.
L'invention concerne les panneaux autoportants et emboîtables formés d'une âme en matière synthétique isolante bordée, sur chacun de ses chants longitudinaux par un profilé collé de section en "U", et présentant une nervure longitudinale de section trapézoïdale, juxtaposée à une rainure de même profil et apte à s'encastrer dans la rainure d'un panneau juxtaposé, cette âme avec ses profilés de jonction étant disposée entre deux parements métalliques collés sur elle et comportant chacun des retours longitudinaux. The invention relates to self-supporting and nestable panels formed of a core of insulating synthetic material bordered, on each of its longitudinal edges by a glued section of "U" section, and having a longitudinal rib of trapezoidal section, juxtaposed with a groove of the same profile and able to fit into the groove of a juxtaposed panel, this core with its junction profiles being disposed between two metal facings glued on it and each comprising longitudinal returns.
Quand des panneaux de ce type sont assemblés par emboîtement, par exemple pour former une paroi verticale, I'encastrement des nervures dans les rainures assure la jonction entre les panneaux et ménage des canaux de bordure, entre les faces en vis à vis des profilés des chants. Ces canaux drainent les eaux de pluie ou de condensation. When panels of this type are assembled by interlocking, for example to form a vertical wall, the embedding of the ribs in the grooves ensures the junction between the panels and cleaning of the edge channels, between the faces opposite the profiles of the chants. These channels drain rain or condensation water.
Lorsque de tels panneaux sont utilisés pour former des éléments de couverture, il s'avère que, même si les panneaux sont disposés avec une pente par rapport à l'horizontale, la jonction entre les panneaux manque d'étanchéité, dans la mesure où elle permet des infiltrations d'eau dans l'isolant et, de là, des écoulements dans le local. When such panels are used to form roofing elements, it turns out that, even if the panels are arranged with a slope relative to the horizontal, the junction between the panels lacks sealing, insofar as it allows water infiltration into the insulation and, from there, flows into the room.
Pour remédier à cela, il est nécessaire d'assurer l'étanchéité entre panneaux par un cordon en matériau d'étanchéité, tel que du silicone, rapporté manuellement dans l'intervalle entre bordures des panneaux ou par une baguette porteuse de joints. Cette opération conduit à une augmentation du temps de pose et du coût de la toiture. To remedy this, it is necessary to seal between panels by a bead of sealing material, such as silicone, added manually in the interval between the edges of the panels or by a strip carrying joints. This operation leads to an increase in the installation time and the cost of the roof.
La présente invention a pour objet de remédier à ces inconvénients en fournissant un panneau autoportant, emboîtable et étanche, supprimant toute reprise d'eau par l'isolant et tout cheminement à l'intérieur du local, sans supprimer les canaux de drainage et sans que le montage nécessite une reprise d'étanchéité. The object of the present invention is to remedy these drawbacks by providing a self-supporting, nestable and waterproof panel, eliminating any water uptake by the insulation and any routing inside the premises, without eliminating the drainage channels and without mounting requires a resumption of sealing.
A cet effet, le panneau selon l'invention comprend, d'une part, des joints d'étanchéité disposés entre les retours longitudinaux des parements, et la face en vis à vis du profilé de jonction correspondant, et, d'autre part et au fond de chaque rainure longitudinale, un joint précomprimé et apte, après encastrement des nervures dans les rainures de l'assemblage de deux panneaux juxtaposés, à combler par expansion élastique l'intervalle ménagé entre le fond de la rainure et le sommet de la nervure et à assurer l'étanchéité de la jonction. To this end, the panel according to the invention comprises, on the one hand, seals arranged between the longitudinal returns of the facings, and the face opposite the corresponding joining profile, and, on the other hand and at the bottom of each longitudinal groove, a precompressed joint capable, after embedding the ribs in the grooves of the assembly of two juxtaposed panels, to fill by elastic expansion the gap formed between the bottom of the groove and the top of the rib and sealing the junction.
Grâce à cet agencement, la pose et l'assemblage des panneaux s'effectuent de manière habituelle, par simple emboîtement et l'étanchéité s'effectue progressivement par expansion élastique des joints disposés dans les gorges des rainures. La durée de cette expansion dépend de la température ambiante, mais est en général de l'ordre de quelques heures. Lorsque ces joints sont parfaitement en contact avec les sommets des nervures, ils forment, dans chaque jonction, une double barrière d'étanchéité qui protège efficacement le local, mais aussi qui, en combinaison avec les joints d'étanchéité des retours longitudinaux, empêchent que les eaux pluviales puissent s'infiltrer entre les profilés en matière synthétique et les parements et, de là, dans l'rame en matière synthétique. Thanks to this arrangement, the installation and assembly of the panels is carried out in the usual manner, by simple interlocking and the sealing takes place progressively by elastic expansion of the joints arranged in the grooves of the grooves. The duration of this expansion depends on the ambient temperature, but is generally of the order of a few hours. When these joints are perfectly in contact with the tops of the ribs, they form, in each junction, a double sealing barrier which effectively protects the room, but also which, in combination with the joints of the longitudinal returns, prevent rainwater can infiltrate between the plastic profiles and the facings and, from there, into the plastic train.
Dans une forme d'exécution de l'invention, chaque joint de fond de gorge est composé d'une mousse en matière synthétique à mémoire de forme composée de cellules ouvertes pré-imprégnées d'une solution caoutchouteuse et est disposée dans cette gorge avec une pré-compression de l'ordre de 90 % pour parvenir, après expansion élastique, à un taux de compression de l'ordre de 75 %. In one embodiment of the invention, each groove bottom seal is composed of a plastic foam with shape memory composed of open cells pre-impregnated with a rubbery solution and is arranged in this groove with a pre-compression of the order of 90% to achieve, after elastic expansion, a compression ratio of the order of 75%.
Cette précompression résiduelle permet de maintenir l'étanchéité à l'eau dans le temps, tout en absorbant les variations dimensionnelles de l'emboîtement par dilatation ou rétraction au fil des saisons. This residual precompression makes it possible to maintain the watertightness over time, while absorbing the dimensional variations of the nesting by expansion or retraction over the seasons.
D'autres caractéristiques et avantages ressortiront de la description qui suit en référence au dessin schématique annexé représentant une forme d'exécution de ce panneau. Other characteristics and advantages will emerge from the description which follows with reference to the appended schematic drawing representing an embodiment of this panel.
Figure 1 est une vue partielle de côté en coupe transversale du panneau,
Figure 2 est une vue partielle de côté en coupe transversale montrant l'assemblage de deux panneaux pour former une couverture.Figure 1 is a partial side view in cross section of the panel,
Figure 2 is a partial side view in cross section showing the assembly of two panels to form a cover.
Comme montré à la figure 1, le panneau est composé d'une âme 2 en matière synthétique isolante, et par exemple en mousse de polystyrène extrudée à cellules fermées. As shown in Figure 1, the panel is composed of a core 2 of insulating synthetic material, and for example of extruded polystyrene foam with closed cells.
Les deux chants longitudinaux de cette âme sont usinés pour recevoir chacun un profilé 3 en matière synthétique, par exemple en polychlorure de vinyle, présentant la forme générale d'un "U" dont les deux ailes 3a et 3b s'engagent dans des logements usinés 4, tandis que l'âme 3c se plaque contre le chant correspondant. Chaque profilé comporte, en saillie de son âme, une nervure longitudinale 5 qui, de section transversale trapézoïdale, est juxtaposée à une gorge 6, de même profil transversal. Le fond de la gorge s'engage dans une rainure 7 usinée dans le chant correspondant de l'âme. La liaison du profilé avec l'rame est assurée par collage en usine.The two longitudinal edges of this core are machined to each receive a profile 3 of synthetic material, for example polyvinyl chloride, having the general shape of a "U" whose two wings 3a and 3b engage in machined housings 4, while the core 3c is pressed against the corresponding edge. Each profile comprises, projecting from its core, a longitudinal rib 5 which, of trapezoidal cross section, is juxtaposed to a groove 6, of the same transverse profile. The bottom of the groove engages in a groove 7 machined in the corresponding edge of the core. The connection of the profile with the train is ensured by factory bonding.
La figure 1 montre bien que les profilés sont inversés, d'un chant à l'autre, de manière que la nervure de chacun d'eux puisse s'emboîter et s'encastrer dans la rainure 6 du panneau juxtaposé, comme montré à la figure 2. Figure 1 shows that the profiles are inverted, from one edge to another, so that the rib of each of them can fit together and fit into the groove 6 of the juxtaposed panel, as shown in figure 2.
Chaque panneau comporte deux parements 8, en aluminium ou acier prélaqué, collé sur l'âme 2 et sur les faces externes des ailes des profilés 3. Les extrémités de ces parements sont munies de retours 9, qui sont rabattus vers l'intérieur du panneau contre les portions d'âme 3c des profilés. Each panel has two facings 8, made of aluminum or prepainted steel, bonded to the core 2 and to the external faces of the wings of the profiles 3. The ends of these facings are provided with returns 9, which are folded inwards towards the inside of the panel. against the core portions 3c of the profiles.
Lorsque de tels panneaux sont assemblés, l'encastrement des nervures 5 dans les rainures 6 assure leur jonction, c'est à dire assure leur positionnement mais aussi leur liaison mécanique, par emboîtement des nervures 5 de section trapézoïdale dans les rainures 6 de même section. La fixation des panneaux sur une structure porteuse est assurée par des vis. When such panels are assembled, the embedding of the ribs 5 in the grooves 6 ensures their junction, that is to say ensures their positioning but also their mechanical connection, by fitting the ribs 5 of trapezoidal section into the grooves 6 of the same section . The panels are fixed to a supporting structure by screws.
Selon l'invention, chacun des panneaux comporte, entre les retours 9 et les parties 3c de l'âme des profilés 3, des joints de bordure 10, constitués par un mastic à base de polyuréthanne déposé en usine. Ces joints assurent l'étanchéité aux infiltrations d'eau, de pluie ou de condensation, et empêchent celles-ci de pénétrer dans l'intervalle entre les ailes des profilés et les parements. According to the invention, each of the panels comprises, between the returns 9 and the parts 3c of the core of the profiles 3, edge seals 10, constituted by a polyurethane-based mastic deposited in the factory. These seals seal against water, rain or condensation infiltration, and prevent it from entering the gap between the profile wings and the facings.
L'étanchéité de l'assemblage des deux panneaux est également assurée par des joints de fond de gorge 12, disposés dans le fond des rainures 10. Chacun de ces joints est composé d'une mousse en matière synthétique, tel qu'en polyuréthanne polyester, avec cellules ouvertes pré-imprégnées d'une solution caoutchouteuse. Cette matière synthétique présente une mémoire de forme et le joint est disposé dans la gorge avec une précompression dont le taux est de l'ordre de 90 %, de manière que son épaisseur E, lors de la pose du panneau, soit inférieure à la distance D entre le fond 6a d'une rainure 6 et le sommet 5a de la nervure 5 s'encastrant dans cette rainure. Ces joints sont mis en place dans le fond des rainures des panneaux pendant la réalisation de la couverture. The tightness of the assembly of the two panels is also ensured by groove bottom seals 12, disposed in the bottom of the grooves 10. Each of these seals is made of a foam of synthetic material, such as polyester polyurethane. , with open cells pre-impregnated with a rubbery solution. This synthetic material has a shape memory and the seal is placed in the groove with a precompression, the rate of which is around 90%, so that its thickness E, when the panel is installed, is less than the distance D between the bottom 6a of a groove 6 and the top 5a of the rib 5 fitting into this groove. These joints are placed in the bottom of the grooves of the panels during the production of the cover.
Lorsque les panneaux autoportants sont posés sur une structure et assemblés par emboîtement pour former une couverture, la mémoire de forme de la matière assure l'expansion élastique de chaque joint 12 qui, progressivement, remplit le fond de la rainure et vient donc en contact avec la face 5a de la nervure correspondante. Dans cet état, la matière constitutive du joint 12 est encore soumise à une compression de l'ordre de 75 %, compression qui assure une parfaite étanchéité à l'eau, dans le temps et au fil des saisons en absorbant les variations dimensionnelles des emboîtements. When the self-supporting panels are placed on a structure and assembled by interlocking to form a cover, the shape memory of the material ensures the elastic expansion of each joint 12 which, gradually, fills the bottom of the groove and therefore comes into contact with the face 5a of the corresponding rib. In this state, the material constituting the seal 12 is still subjected to a compression of the order of 75%, compression which ensures a perfect seal against water, over time and over the seasons by absorbing the dimensional variations of the sockets .
On notera que la présence d'un joint dans chacune des deux rainures d'une jonction entre deux panneaux forme une double barrière d'étanchéité qui garantit ainsi toute infiltration des eaux pluviales à l'intérieur du local. Ces eaux pluviales, passant dans l'intervalle 13 entre les retours coudés des parements 8, sont drainées par le canal 14 formé entre les profilés 3 de deux panneaux contigus. It will be noted that the presence of a seal in each of the two grooves of a junction between two panels forms a double sealing barrier which thus guarantees any infiltration of rainwater inside the premises. These rainwater, passing in the interval 13 between the bent returns of the facings 8, are drained by the channel 14 formed between the sections 3 of two adjoining panels.
Il ressort de ce qui précède que, grâce à leurs moyens d'étanchéité intégrés, les panneaux autoportants emboîtables selon l'invention permettent d'obtenir une couverture étanche dans le temps, dès leur emboîtement et sans avoir recours à aucune pièce complémentaire. It appears from the above that, thanks to their integrated sealing means, the self-supporting nestable panels according to the invention make it possible to obtain a waterproof cover over time, as soon as they fit together and without having to resort to any additional part.
