Description
PROFILE EN T INVERSE POUR REALISER UNE STRUCTURE DE SUPPORT DE FAUX-PLAFONDS La présente invention concerne un profilé en T inversé pour réaliser une structure de support de faux-plafonds.The present invention relates to an inverted T-shaped section for producing a support structure for false ceilings.
On connaît des éléments structurels de support de faux-plafonds constitués d'une pluralité de longerons (profilés en T inversé d'une longueur d'environ 3 m) qui sont couplés longitudinalement entre eux, et reliés par une pluralité de traverses (également en T inversé) qui s'insèrent par leurs extrémités dans des trous oblongs verticaux adaptés creusés dans les io raidisseurs des longerons. En particulier, chaque profilé en T est obtenu par pliage, découpage et formage d'une bande métallique pour réaliser un raidisseur central vertical qui, sur la partie supérieure, forme un tube et qui, sur la partie inférieure, se forme en deux ailettes horizontales coplanaires. Lors de la phase de 15 profilage, on connaît également l'application sur la surface inférieure des ailettes d'un revêtement métallique préverni pour conférer au profilé un aspect extérieur agréable. De tels profilés connus ont néanmoins pour inconvénient que, pendant la formation du profilé, sur les ailes ou ailettes de ce dernier, se 20 forment des ondulations et/ou des imperfections qui se répercutent sur le revêtement préverni des ailes elles-mêmes. Il en résulte un aspect extérieur désagréable de la surface externe du revêtement qui constitue la partie visible de la structure. Le but de l'invention est d'éliminer de tels inconvénients et de 25 réaliser un profilé qui soit exempt d'ondulations et/ou d'imperfections sur la surface du revêtement métallique qui recouvre les ailes. Un tel objectif est atteint selon l'invention grâce à un profilé en T inversé pour réaliser une structure de support de faux-plafonds qui est obtenu par pliage, découpage et formage d'une bande métallique pour 30 former un raidisseur central vertical qui, sur la partie supérieure, forme un tube et sur la partie inférieure, se termine en deux ailettes horizontales coplanaires, lesdites ailettes du profilé étant recouvertes par un revêtement préverni appliqué lors de la même phase de profilage que le profilé en T, caractérisé en ce que la surface des ailettes est dotée d'au moins un siège longitudinal avec une cavité orientée vers le bas, la largeur de l'ouverture dudit siège étant comprise entre 1/5ème et 2/5ème de la largeur totale de l'ailette.False ceilings supporting structural members are known consisting of a plurality of longitudinal members (inverted T-sections with a length of about 3 m) which are coupled longitudinally with each other and connected by a plurality of sleepers (also in T inverted) which are inserted by their ends into suitable vertical oblong holes dug in the stiffeners of the longitudinal members. In particular, each T-section is obtained by folding, cutting and forming a metal strip to produce a vertical central stiffener which, on the upper part, forms a tube and which, on the lower part, is formed in two horizontal fins coplanar. During the profiling phase, it is also known to apply a pre-finished metal coating to the lower surface of the fins to give the profile a pleasant external appearance. Such known profiles, however, have the disadvantage that, during the formation of the profile, on the wings or fins of the latter, undulations and / or imperfections are formed which have repercussions on the pre-finished coating of the wings themselves. This results in an unpleasant external appearance of the outer surface of the coating which constitutes the visible part of the structure. The object of the invention is to eliminate such drawbacks and to make a profile which is free of corrugations and / or imperfections on the surface of the metal coating which covers the wings. Such an object is achieved according to the invention by means of an inverted T-profile for producing a false ceiling support structure which is obtained by folding, cutting and forming a metal strip to form a vertical central stiffener which on the upper part, forming a tube and on the lower part, ends in two horizontal fins coplanar, said fins of the profile being covered by a pre-coated coating applied during the same profiling phase as the T-section, characterized in that the fin surface is provided with at least one longitudinal seat with a cavity facing downwards, the width of the opening of said seat being between 1 / 5th and 2 / 5th of the total width of the fin.
Selon d'autres caractéristiques de l'invention : - le siège a une forme en section de trapèze isocèle ; - le siège a une forme arrondie ; - la base la plus petite du siège est dotée d'une nervure avec une cavité orientée vers le revêtement préverni. io La présente invention sera ci-après décrite en référence aux dessins annexés dans lesquels : - la figure 1 est une vue en perspective d'un profilé en T selon l'invention ; - la figure 2 représente le détail agrandi des ailettes avec le 15 revêtement préverni ; - la figure 3 représente une variante du mode de réalisation ; et - la figure 4 représente une autre variante du mode de réalisation de l'invention. Comme on le voit sur les figures, le profilé 2 en T inversé selon 20 l'invention est obtenu par pliage, découpage et formage d'une bande métallique pour réaliser un raidisseur central vertical 4 qui, sur sa partie supérieure, forme un tube 6 et qui, sur sa partie inférieure, se forme en deux ailettes horizontales coplanaires 8. Chaque ailette 8 est profilée de façon appropriée pour réaliser un 25 siège longitudinal 10 comportant une cavité orientée vers le bas de section transversale sensiblement trapézoïdale et dont la largeur de la base la plus grande est comprise entre 1/5ème et 2/5ème de la largeur transversale totale de l'ailette 8, ce qui confère un degré élevé de résistance à la déformation. Sur la surface inférieure des ailettes, pendant la phase de profilage, 30 un revêtement préverni 12 est appliqué, le revêtement présentant des bords 14 repliés en U pour recouvrir les extrémités 6 de l'ailette 8. Il en résulte que le profilé selon l'invention présente un aspect extérieur agréable de la partie visible du fait de la présence du siège 10 qui empêche l'apparition d'effets d'ondulation sur les ailettes et sur le revêtement verni ou préverni. Dans la variante du mode de réalisation illustrée à la figure 3, la base la plus petite 18 du siège 10 est munie d'une nervure 20 avec une cavité orientée vers le revêtement préverni 12. Dans la variante du mode de réalisation illustrée à la figure 4, chaque ailette 8 comporte de deux sièges 10.According to other characteristics of the invention: the seat has an isosceles trapezium sectional shape; - the seat has a rounded shape; - The smaller base of the seat has a rib with a cavity facing the pre-coated. The present invention will hereinafter be described with reference to the accompanying drawings in which: - Figure 1 is a perspective view of a T-section according to the invention; Figure 2 shows the enlarged detail of the fins with the pre-coated coating; FIG. 3 represents a variant of the embodiment; and - Figure 4 shows another variant of the embodiment of the invention. As can be seen in the figures, the inverted T-shaped section 2 according to the invention is obtained by folding, cutting and forming a metal strip to produce a vertical central stiffener 4 which, on its upper part, forms a tube 6. and which, on its lower part, is formed in two coplanar horizontal fins 8. Each fin 8 is suitably profiled to provide a longitudinal seat 10 having a downwardly oriented cavity of substantially trapezoidal cross section and whose width is The largest base is between 1 / 5th and 2 / 5th of the total transverse width of the fin 8, which confers a high degree of resistance to deformation. On the lower surface of the fins, during the profiling phase, a pre-coated coating 12 is applied, the coating having U-folded edges 14 to cover the ends 6 of the fin 8. As a result, the profile according to FIG. The invention has a pleasing external appearance of the visible part due to the presence of the seat 10 which prevents the appearance of corrugation effects on the fins and on the varnished or pre-coated coating. In the variant of the embodiment illustrated in FIG. 3, the smallest base 18 of the seat 10 is provided with a rib 20 with a cavity facing the pre-coated surface 12. In the variant of the embodiment illustrated in FIG. 4, each fin 8 has two seats 10.
