Abstract

The roofing panel includes pref. metallic sheets (3) separated from a framework of mounting elements (1) by a regular array of spacers (4). These spacers create cavities (E) between the panels (3) and the framework elements in which air can circulate to prevent condensation. Air pref. enters through an aperture (e) near the lower edge of a panel and is discharged through an opening (s) near the upper panel edge provided by the cowling (5). Thin plates (8) of e.g. heat insulating material are pref. fitted between the framework elements to form a smooth interior surface.

Description

La présente invention concerne une couverture pour des constructions diverses, notamment du type comportant des panneaux, en particulier métalliques, qui sont montés à bords jointifs sur une charpente. The present invention relates to a cover for various constructions, in particular of the type comprising panels, in particular of metal, which are mounted with contiguous edges on a frame.

Les couvertures de ce type connu, dans lesquelles les panneaux sont fixés directement aux pannes de la charpente, présentent l'inconvénient suivant : leur face inférieure est mal ventilée en raison de ce que les pannes s'opposent à la circulation de l'air transversalement auxdites pannes. Cette ventilation insuffisante est particulièrement gênante dans le cas des couvertures à panneaux métalliques, lorsqu'elles sont exposées à un fort ensoleillement, et aussi par temps froid, en raison de Ba condensation de vapeur qui se produit alors sur les faces i inférieures des panneaux métalliques. Roofs of this known type, in which the panels are fixed directly to the purlins of the frame, have the following drawback: their underside is poorly ventilated due to the fact that the faults obstruct the flow of air transversely said breakdowns. This insufficient ventilation is particularly troublesome in the case of metal panel covers, when they are exposed to strong sunlight, and also in cold weather, due to the condensation of vapor which then occurs on the lower faces of the metal panels. .

La couverture selon l'invention est du type indiqué i initialement, mais elle ne présente pae l'incon- vénient qui vient d'être mentionné; elle est caractérisée en ce que des profilés formant des créneaux ou des ondulations réguliers, de hauteur h1, sont intercalés entre les panneaux de la couverture et les pannes de la charpente, auxquelles lesdits profilés au moins sont fixés, de façon à dégager entre les panneaux de la couverture et la charpente un espace libre pour la cir- culation de l'air. The blanket according to the invention is of the type indicated initially, but it does not have the drawback which has just been mentioned; it is characterized in that profiles forming slots or regular undulations, of height h1, are interposed between the panels of the roof and the purlins of the frame, to which said profiles at least are fixed, so as to clear between the panels of the cover and the frame a free space for air circulation.

En plus de permettre une ventilation efficace de sa face inférieure et d'éviter toute condensation, la couverture selon la présente invention offre l'avan- tage suivant : au lieu d'être fixés directement dans les pannes au moyen de vis, de crochets, etc.., de longueur relativement importante, les panneaux de la couverture peuvent être fixés directement aux sommets, de préférence plats, des créneaux des profilés intercalaires, par des vis, des rivets .. etc.., de longueur beaucoup plus courte, puisque ces derniers organes de fixation n'ont qu'à traverser la faible épaisseur du profilé (par exemple en t81e de 1, 5 m
À titre d'exemples, on a décrit ci-dessous et illustré schématiquement au dessin annexé plusieurs formes de réalisation de la couverture selon l'invention.In addition to allowing effective ventilation of its underside and avoiding any condensation, the cover according to the present invention offers the following advantage: instead of being fixed directly in the purlins by means of screws, hooks, etc., of relatively long length, the cover panels can be fixed directly to the vertices, preferably flat, of the slots of the intermediate profiles, by screws, rivets, etc., of much shorter length, since these latter fasteners only have to pass through the small thickness of the profile (for example in t81e of 1.5 m
By way of examples, several embodiments of the cover according to the invention have been described below and illustrated diagrammatically in the appended drawing.

La figure 1 représente une première forme de réalisation de la couverture selon l'invention, à pente unique, en coupe par un plan vertical, perpendiculaire aux pannes de la charpente. FIG. 1 represents a first embodiment of the cover according to the invention, with a single slope, in section through a vertical plane, perpendicular to the purlins of the frame.

La figure 2 est une vue en coupe suivant la ligne II-II de la figure 1. Figure 2 is a sectional view along line II-II of Figure 1.

Les figures 3, 4 et 5 sont des vues en coupe, analogues à la figure 2, de trois autres formes de réalisation. Figures 3, 4 and 5 are sectional views, similar to Figure 2, of three other embodiments.

Gans la forme de réalisation illustrée sur les figures 1 et 2, I désigne les pannes de la charpente dune toiture à pente unique, supportée par des murs tels que 2a et Zb (les chevrons de cette charpente ne sont pas représentés). 3 désigne des panneaux de couverture, de préférence métalliques, par exemple en tôle zinguée, qui sont placés à bords jointifs, de façon connue en soi. Dans la forme de réalisation considérée, chacun de ces panneaux de couverture forme des créneaux, parallèles et réguliers, 3a, de hauteur h2 (figure 2). In the embodiment illustrated in FIGS. 1 and 2, I denotes the purlins of the frame of a single-pitched roof, supported by walls such as 2a and Zb (the rafters of this frame are not shown). 3 designates cover panels, preferably metallic, for example of galvanized sheet metal, which are placed with contiguous edges, in a manner known per se. In the embodiment considered, each of these cover panels forms slots, parallel and regular, 3a, of height h2 (FIG. 2).

Selon la présente invention, des profilés 4, de préférence métalliques, formant des créneaux réguliers 4a, de hauteur a , sont intercalés entre les panneaux 3 de la couverture et les pannes 1 de la charpente. Comme visible sur la figure 2, ces profilés intercalaires 4 et leurs créneaux 4a sont adaptés pour permettre 1Ben- gagement des créneaux 3a des panneaux 3 de la couverture sur les sommets plats desdits créneaux 4a, dont la hauteur h1 est notablement supérieure à h2. De ce fait, un espace libre E, de hauteur voisine de (h1-h2), est dégagé entre les panneaux 3 de la couverture et les pannes 1 de la charpente, de façon à permettre la libre circulation de l'air au-dessus desdites pannes. According to the present invention, profiles 4, preferably metallic, forming regular slots 4a, of height a, are interposed between the panels 3 of the cover and the purlins 1 of the frame. As can be seen in FIG. 2, these intermediate sections 4 and their slots 4a are adapted to allow 1Benagement of the slots 3a of the panels 3 of the cover on the flat tops of said slots 4a, the height h1 of which is significantly greater than h2. Therefore, a free space E, of height close to (h1-h2), is cleared between the panels 3 of the roof and the purlins 1 of the frame, so as to allow the free circulation of air above said failures.

Une entrée d'air e est amenagée entre le bord inférieur de la couverture et le bord supérieur du mur correspon- dant 2a. Une sortie d'air s est aménagée près du bord su périeur de la couverture, en particulier en la délimi- tant au moyen d'un capot en t81e 5, par exemple un pro filé en V régnant le long du fartage de la toiture.An air inlet e is provided between the lower edge of the cover and the upper edge of the corresponding wall 2a. An air outlet is arranged near the upper edge of the cover, in particular by delimiting it by means of a cover in shape 5, for example a V-shaped profile prevailing along the waxing of the roof.

Les profilés 4 sont réalisés par exemple en acier galvanisé d'épaisseur voisine de 1,5 mm. Leur largeur, de par exemple 60 mm, de même que leur longueur, sont adaptées à celles des pannes 1, sur lesquelles leurs parties planes 4b, entre les créneaux 4a, sont fixées par tous moyens appropriés, comme indiqué en 6. The profiles 4 are made for example of galvanized steel with a thickness close to 1.5 mm. Their width, of for example 60 mm, as well as their length, are adapted to those of the purlins 1, on which their flat parts 4b, between the slots 4a, are fixed by any appropriate means, as indicated in 6.

Quant aux panneaux de couverture 3, leurs créneaux 3a peuvent être fixés directement aux sommets plats des créneaux 4a des profilés 4, par tous moyens appropriés, comme indiqué en 7. Des plaques minces 8 (figure 1) en un matériau thermiquement isolant peuvent entre interposées entre les pannes adjacentes 1,
Dans la forme de réalisation illustre sur la figure 3, les panneaux 3 de la couverture et les pro filés intercalaires 4 peuvent être analogues a ceux illustrés sur les figures a et 2, et précédemment décrits Cependant , ce sont les parties planes étroites 4a des profilés 4 qui sont appliquées sur et fixées à la panne correspondante 1, tandis que les panneaux 5 sont appliqués sur et éventuellement fixés aux parties planes les plus larges, 4b, des profilés 4.As for the cover panels 3, their slots 3a can be fixed directly to the flat tops of the slots 4a of the profiles 4, by any appropriate means, as indicated in 7. Thin plates 8 (FIG. 1) made of a thermally insulating material can be interposed between adjacent faults 1,
In the embodiment illustrated in FIG. 3, the panels 3 of the cover and the intermediate profiles 4 can be similar to those illustrated in FIGS. A and 2, and previously described. However, these are the narrow flat parts 4a of the profiles. 4 which are applied to and fixed to the corresponding purlin 1, while the panels 5 are applied to and possibly fixed to the widest planar parts, 4b, of the sections 4.

La forme de réalisation illustrée sur la figure 4 ne diffère de celle de la figure 3 que par le fait que des plaques minces en tale 9, notamment en forme de plateaux à bords repliés, l'un intérieurement, 9a, et l'autre extérieurement, 9b, sont insérées entre les pannes I et les profilés 4 fixés sur elles, de façon à former une paroi sensiblement lisse du côté intérieur de la couverture.Dans l'exemple illustré, les bords jointifs de deux plateaux contigus 9 sont assemblés par engagement du rebord 9a de l'un dans le rebord 9b de l'autre. D'autre part, une matière thermiquement isolante, 10, telle que de la laine de verre ou de roche, est placée sur les plateaux 9, y compris au niveau des créneaux 4b des prof ilés 4, de façon à laisser un espace libre en dessous des panneaux 3. The embodiment illustrated in FIG. 4 differs from that of FIG. 3 only by the fact that thin plates in sheet 9, in particular in the form of trays with folded edges, one internally, 9a, and the other externally , 9b, are inserted between the purlins I and the profiles 4 fixed on them, so as to form a substantially smooth wall on the inside of the cover. In the example illustrated, the contiguous edges of two contiguous plates 9 are assembled by engagement from the rim 9a of one into the rim 9b of the other. On the other hand, a thermally insulating material, 10, such as glass wool or rock wool, is placed on the plates 9, including at the level of the slots 4b of the profiles 4, so as to leave a free space in below the panels 3.

Cette forme de réalisation offre l'avantage de présenter une isolation thermique de la couverture, qui est très bonne, non seulement en raison de l'isolant 10, mais aussi du fait de la couche d'air enfermée entre les panneaux 3 de la couverture et ledit isolant 10; il n'existe en fait, entre les panneaux 3 et les plateaux 9, que des "ponts thermiques" très étroits, correspondant à leurs faibles surfaces de contact avee les profilés métalliques 4. This embodiment offers the advantage of having thermal insulation of the roof, which is very good, not only because of the insulation 10, but also because of the air layer enclosed between the panels 3 of the roof. and said insulator 10; there are in fact, between the panels 3 and the plates 9, only very narrow "thermal bridges", corresponding to their small contact surfaces with the metal profiles 4.

La forme de réalisation illustrée sur la figure 5 ne diffère de celle illustrée sur la figure 4, que par le fait que les plateaux 9 de la figure 4 sont remplacés, sur la figure 5, par des panneaux 11, analogues aux panneaux 3, et comportant par exemple des créneaux 11a, disposés régulièrement au niveau des parties 4b des profilés intercalaires 4. The embodiment illustrated in FIG. 5 differs from that illustrated in FIG. 4 only by the fact that the plates 9 of FIG. 4 are replaced, in FIG. 5, by panels 11, similar to panels 3, and comprising, for example, slots 11a, regularly arranged at the level of parts 4b of the intermediate sections 4.

La présente invention n'est pas limitée aux formes de réalisation précédemment décrites : elle englobe toutes leurs variantes, Les panneaux 3 de la couverture et/ou les profilés intercalaires 4, au lieu entre métalliques, peuvent & re en matière isolante, notamment en matière synthétique. Au lieu de former des créneaux réguliers, les panneaux 3 et/ou les profilés 4 peuvent former des ondulations régulières de forme quelconque. Les panneaux de couverture 3 peuvent aussi titre entièrement plats, sans créneaux ni ondulations. The present invention is not limited to the embodiments described above: it encompasses all their variants, The panels 3 of the cover and / or the intermediate sections 4, instead of between metal, can be of insulating material, in particular of synthetic. Instead of forming regular slots, the panels 3 and / or the profiles 4 can form regular corrugations of any shape. The cover panels 3 can also be entirely flat, without slots or undulations.
