Suits any make of panel, good for fixing with existing sheeted roofs.

Description

Structure préfabriquée autoportante de panneau de recouvrement et de costière de coupole d'éclairage, pour toitures.Prefabricated self-supporting structure of cover panel and light dome curb, for roofs.

L'invention qui se situe dans le domaine des panneaux de recouvrement et des costières de coupole d'éclairage, destinés à la construction de toitures, concerne plus particulièrement une nouvelle structure préfabriquée desdits panneaux, qui favorise leur jonction. The invention which lies in the field of covering panels and curbs of a lighting dome, intended for the construction of roofs, relates more particularly to a new prefabricated structure of said panels, which promotes their joining.

Les panneaux préfabriqués de recouvrement, très largement utilisés pour la réalisation de toitures, de même que les costières qui reçoivent les coupoles d'éclairage et qui sont disposées de place en place sur le toit, doivent être -fixés et assemblés les uns aux autres de telle façon qu' ils puissent supporter des dilatations liées aux contraintes thermiques, qu'ils soient étanches au niveau de leurs liaisons et permettent le drainage des eaux. The prefabricated covering panels, very widely used for the realization of roofs, as well as the curbs which receive the lighting domes and which are arranged from place to place on the roof, must be -fixed and assembled to each other from in such a way that they can withstand expansions linked to thermal stresses, that they are watertight at their connections and allow the drainage of water.

A cet effet, on utilise avantageusement des structures autoportantes contituées de deux peaux en matière plastique moulées formant deux coques à l'intérieur desquelles est placé un matériau de remplissage du genre d'une mousse. La peau supérieure est profilée pour former des nervures qui constituent des raidisseurs, nervures qui favorisent le drainage et participent à l'esthétique de la toiture. Dans le sens longitudinal, ctest-à-dire dans le sens de la pente du toit, chaque panneau est pourvu intérieurement d'au moins deux poutres longitudinales qui en constituent l'armature. Pour que chaque panneau se raccorde à son voisin, on prévoit avantageusement qu'une poutre latérale est profilée - par exemple en formant un arrondi, tandis que la poutre latérale opposée se prolonge par un rebord formant une nervure qui peut coiffer l'arrondi du panneau voisin.Les panneaux se chevauchent ainsi sur toute la longueur du toit. Mais malgré cela il subsiste des problèmes au niveau du raccordement de deux panneaux entre eux, ou des panneaux et d'une costière dont les bordures inférieures sont réalisées de la même façon.  For this purpose, it is advantageous to use self-supporting structures made up of two molded plastic skins forming two shells inside which is placed a filling material of the kind of a foam. The upper skin is profiled to form ribs which constitute stiffeners, ribs which promote drainage and participate in the aesthetics of the roof. In the longitudinal direction, that is to say in the direction of the slope of the roof, each panel is internally provided with at least two longitudinal beams which constitute its frame. For each panel to be connected to its neighbor, it is advantageously provided that a lateral beam is profiled - for example by forming a rounding, while the opposite lateral beam is extended by a rim forming a rib which can cover the rounding of the panel The panels overlap over the entire length of the roof. But despite this there are still problems with connecting two panels together, or panels and a curb whose lower edges are made in the same way.

En effet malgré le soin apporté à leur fabrication, il subsiste souvent au niveau des chevauchements un jeu entre les panneaux qui crée des problèmes d'étanchéité et de pont thermique. Indeed despite the care taken in their manufacture, there often remains at the overlaps a clearance between the panels which creates problems of sealing and thermal bridge.

Cet inconvénient est d'autant plus sensible, que les panneaux à raccorder sont de fabrications différentes, par exemple quand il s'agit d'intégrer à une toiture existante, une costière de coupole d'éclairage provenant d'un autre fabricant. This drawback is all the more significant, as the panels to be connected are of different manufacturers, for example when it comes to integrating into an existing roof, a lighting dome curb from another manufacturer.

L'invention s'est donc fixée comme objectif de réaliser des panneaux autoportants de recouvrement qui présentent notamment l'avantage de pouvoir se juxtaposer à tout type de panneau autoportant en évitant les inconvénients précités. The invention has therefore set itself the objective of producing self-supporting covering panels which in particular have the advantage of being able to be juxtaposed with any type of self-supporting panel while avoiding the aforementioned drawbacks.

Un objet principal de la présente invention consiste donc en une structure préfabriquée de panneau autoportant comportant une peau inférieure et une peau supérieure de part et d'autre d'un matériau de remplissage, dont la peau supérieure est profilée pour former des nervures longitudinales, ladite structure renfermant des poutres latérales dont l'une présente le profil d'une nervure longitudinale, structure selon laquelle au moins une poutre profilée est creusée, sur l'épaisseur du panneau d'une rainure ouverte vers le bas qui s'étend sur toute la longueur du panneau et qui délimite avec le bord du panneau autoportant voisin une alvéole servant de logement à un joint apte à encaisser des écrasements dûs aux irrégularités des panneaux eux-mêmes et/ou à leurs défauts de positionnement réciproque. A main object of the present invention therefore consists of a prefabricated structure of a self-supporting panel comprising a lower skin and an upper skin on either side of a filling material, the upper skin of which is profiled to form longitudinal ribs, said structure containing lateral beams, one of which has the profile of a longitudinal rib, structure according to which at least one profiled beam is dug, over the thickness of the panel with a groove open downward which extends over the entire length of the panel and which delimits, with the edge of the neighboring self-supporting panel, a cell serving as a housing for a seal capable of collecting crushing due to the irregularities of the panels themselves and / or their reciprocal positioning defects.

Selon une caractéristique particulière de l'invention, au-delà de l'autre poutre latérale, la peau supérieure du panneau se prolonge par un rebord qui se développe à l'extérieur du panneau et qui est profilé comme une nervure longitudinale. According to a particular characteristic of the invention, beyond the other lateral beam, the upper skin of the panel is extended by a flange which develops outside the panel and which is profiled like a longitudinal rib.

Avantageusement, entre la poutre latérale non profilée et le rebord, la peau supérieure du panneau se prolonge par une partie plane qui se continue par la partie inclinée du rebord, pour augmenter les dimensions de l'alvéole prévue pour le joint, entre deux panneaux voisins. Advantageously, between the non-profiled lateral beam and the flange, the upper skin of the panel is extended by a flat part which is continued by the inclined part of the flange, to increase the dimensions of the cell provided for the joint, between two neighboring panels. .

D'autres caractéristiques particulières et avantages de l'invention apparaîtront à la lecture de la description qui va suivre, d'un exemple non limitatif de réalisation faisant référence aux dessins annexés qui représentent. Other particular characteristics and advantages of the invention will appear on reading the description which follows, of a nonlimiting example of embodiment referring to the appended drawings which represent.

Figure 1 une vue partielle en perspective d'un panneau autoportant
Figure 2 une vue en coupe montrant deux panneaux voisins raccordés.Figure 1 a partial perspective view of a self-supporting panel
Figure 2 a sectional view showing two neighboring panels connected.

Dans l'exemple représenté à la figure 1, le panneau autoportant désigné dans son ensemble par la référence 1 est consitué d'une peau inférieure 2, d'une peau supérieure 3, de poutres latérales 4, et d'un matériau de remplissage 5 entre les peaux. La peau supérieure est avantageusement profilée pour former des nervures longitudinales 6. Une des poutres latérales 4a est profilée en forme de pointe pour correspondre justement à la nervure latérale 6a. Du côté opposé la poutre latérale 4b est de section- carrée ou rectangulaire et se situe entre les parties planes des deux peaux. In the example shown in Figure 1, the self-supporting panel as a whole designated by the reference 1 consists of a lower skin 2, an upper skin 3, side beams 4, and a filling material 5 between the skins. The upper skin is advantageously profiled to form longitudinal ribs 6. One of the lateral beams 4a is profiled in the shape of a point to correspond precisely to the lateral rib 6a. On the opposite side, the lateral beam 4b is of square or rectangular cross-section and is located between the flat parts of the two skins.

La peau supérieure 3 se prolonge au-delà de ladite poutre par un rebord 7 qui se développe à l'extérieur du panneau et qui peut ainsi coiffer la nervure du panneau voisin. Le rebord 7 présente un profil en pointe qui correspond à celui de la poutre 4a. The upper skin 3 is extended beyond said beam by a flange 7 which develops outside the panel and which can thus cover the rib of the neighboring panel. The rim 7 has a pointed profile which corresponds to that of the beam 4a.

La poutre profilée 4a, sur l'épaisseur e du panneau 1, est creusée latéralement d'une rainure 8 ouverte vers le bas qui s'étend sur toute la longueur du panneau. La partie latérale extrême de la poutre 4a dispose donc d'un épaulement rectiligne 9 au-dessus de la rainure. Du côté opposé, entre la poutre latérale 4b et le rebord 7, la peau supérieure 3 se prolonge par une partie plane 10 qui se continue par la partie inclinée du rebord 7. The profiled beam 4a, on the thickness e of the panel 1, is hollowed out laterally with a groove 8 open downwards which extends over the entire length of the panel. The extreme lateral part of the beam 4a therefore has a rectilinear shoulder 9 above the groove. On the opposite side, between the lateral beam 4b and the rim 7, the upper skin 3 is extended by a flat part 10 which is continued by the inclined part of the rim 7.

Quand on vient placer le panneau autoportant 1 de la figure 1 contre un autre peanneau existant 1' comme le montre la figure 2, le rebord 7 du premier coiffe la nervure 6a' du panneau voisin. On notera qu'une alvéole 11 subsiste entre la poutre 4a' du panneau 1' et la poutre 4b du panneau 1, alvéole obtenue grâce à la rainure 8 d'une part et à la partie plane 10 d'autre part qui en augmente les dimensions. Cette alvéole 11 sert de logement à un joint à mousse rémanente 12 qui peut être collé. When the self-supporting panel 1 of FIG. 1 is placed against another existing panel 1 ′ as shown in FIG. 2, the rim 7 of the first cap covers the rib 6a ′ of the neighboring panel. It will be noted that a cell 11 remains between the beam 4a 'of the panel 1' and the beam 4b of the panel 1, a cell obtained by virtue of the groove 8 on the one hand and the flat part 10 on the other hand which increases the dimensions. This cell 11 serves as a housing for a residual foam seal 12 which can be glued.

Quelle que soit la façon dont s'emboîtent les panneaux voisins, et quelles que soient les irrégularités des bordures des panneaux, le joint 12, avantageusement plus épais que la largeur des alvéoles, va encaisser des compressions ou écrasements dûs aux irrégularités des panneaux ou aux défauts d'alignement ou de positionnement réciproque inhérents à leur montage. Whatever the way in which the neighboring panels fit together, and whatever the irregularities of the edges of the panels, the joint 12, advantageously thicker than the width of the cells, will experience compression or crushing due to the irregularities of the panels or to the misalignment or reciprocal positioning inherent in their mounting.

Le joint est avantageusement collé à l'avance dans l'avéole 11 du panneau. On voit à la figure 2 qu'il est un peu écrasé entre les poutres des deux panneaux voisins et contribue ainsi à l'étanchéité de la jonction. L'invention ne se limite pas à cette forme particulière de réalisation, mais en englobe aussi les variantes. Ainsi les costières recevant les coupoles d'éclairage dont les bordures sont conçues de la même façon que le panneau décrit, s'intégrent aisément en bordure de panneaux existants et la présense du joint permet l'adaptation à n'importe quel autre panneau.  The joint is advantageously glued in advance into the panel 11 of the panel. We see in Figure 2 that it is slightly crushed between the beams of the two adjacent panels and thus contributes to the tightness of the junction. The invention is not limited to this particular embodiment, but also encompasses its variants. Thus the curbs receiving the lighting domes, the edges of which are designed in the same way as the panel described, are easily integrated into the edge of existing panels and the presence of the joint allows adaptation to any other panel.
