Abstract

Device for hanging a member having a horizontal plane lower face, for example having a C-shaped cross-section. This device is formed from a piece of sheet metal bent back over itself in order to form a loop, this loop having : - a horizontal lower side 8 having a length matching the width of the member 1; - two vertical lateral sides 9, 10, located on either side of the lower side and having a height at least equal to that of the member; - two sloping parts 11, 12 each extending one of the lateral sides and converging while rising; - two horizontal end parts 13, 14 each extending a sloping part and each pierced with a hole 15, 16 through which a single vertical supporting rod 17 may pass, which rod ensures that the end parts are superimposed and supports the assembly. Since the member is more securely supported, it is possible to reduce the number of hanging points. Application to the installation of false ceilings.

Description

La présente invention est relative à un dispositif destiné à suspendre un profilé horizontal à un plafond, ce profilé ayant une face inférieure plutôt horizontale; en particulier un profilé ayant une section en C, plus précisément une section en forme de rectangle dont un côté vertical est supprimé dans sa partie centrale. The present invention relates to a device intended to suspend a horizontal profile from a ceiling, this profile having a rather horizontal lower face; in particular a profile having a section in C, more precisely a section in the shape of a rectangle, one vertical side of which is removed in its central part.

De tels profilés sont d'usage courant, notamment comme éléments de maintien de faux-plafonds. Généralement, pour les fixer au plafond, on utilise un dispositif de suspension ou "suspente" obtenu par découpe d'un fer plat. Le dispositif est fixé, à sa partie supérieure sur la face latérale d'une poutre perpendiculaire au profilé, et sa partie inférieure présente une forme analogue à celle d'un crochet, et vient s'engager sous l'aile supérieure horizontale du profilé. Such profiles are in common use, in particular as elements for holding false ceilings. Generally, to fix them to the ceiling, a suspension or "hanger" device obtained by cutting a flat iron is used. The device is fixed, at its upper part to the lateral face of a beam perpendicular to the profile, and its lower part has a shape similar to that of a hook, and engages under the horizontal upper wing of the profile.

Un tel disositif présente l'inconvénient que sous une surcharge, le profilé tend à se déformer par inflexion de l'aile supérieure et/ou vrillage de l'ensemble, d'où mésalignement et risque d'accident. On remédie habituellement à ce risque en renforçant le profilé, au voisinage du point de suspension, avec une pièce à section en C tourné à l'opposé de la section du profilé et qui vient envelopper les ailes supérieure et inférieure. Cette solution oblige à prévoir des pièces supplémentaires, et complique le travail de pose. Such a device has the disadvantage that under an overload, the profile tends to deform by inflection of the upper wing and / or twisting of the assembly, hence misalignment and risk of accident. This risk is usually remedied by reinforcing the profile, in the vicinity of the suspension point, with a piece with a C section turned opposite to the section of the profile and which envelops the upper and lower wings. This solution requires the provision of additional parts, and complicates the installation work.

Le but de l'invention est de fournir un dispositif de suspension qui évite ou limite les inconvénients qu'on vient de décrire, c' est-à-dire les risques de déformation du profilé en cas de surcharge, rendant généralement inutile la pose de renforts, et qui soit en même temps léger et peu coûteux d'obtention et de mise en place. The object of the invention is to provide a suspension device which avoids or limits the drawbacks which have just been described, that is to say the risks of deformation of the profile in the event of overload, generally making the installation of reinforcements, and which is at the same time light and inexpensive to obtain and set up.

Pour obtenir ce résultat, le dispositif selon l'invention est formé d'une pièce de tôle métallique repliée sur elle-même pour former une boucle, cette boucle ayant
- un côté inférieur horizontal de longueur adaptée à la largeur du profilé
- deux côtés latéraux verticaux, situés de part et d'autre du côté inférieur et de hauteur au moins égale à celle du profilé
- deux parties obliques, prolongeant chacune un des côtés latéraux et se rapprochant en montant
- deux parties terminales, horizontales, prolongeant chacune une partie oblique et percées chacune d'un trou qui peut être traversé par une même tige verticale de support qui assure la superposition des parties terminales et le soutien de l'ensemble.To obtain this result, the device according to the invention is formed of a piece of metal sheet folded back on itself to form a loop, this loop having
- a horizontal lower side of length adapted to the width of the profile
- two vertical lateral sides, located on either side of the lower side and of height at least equal to that of the profile
- two oblique parts, each extending one of the lateral sides and approaching when going up
- two end parts, horizontal, each extending an oblique part and each pierced with a hole which can be crossed by the same vertical support rod which ensures the superposition of the end parts and the support of the assembly.

Avantageusement, le dispositif comporte des trous percés à l'avance pour la mise en place d'un organe (22) d'immobilisation du profilé. Advantageously, the device comprises holes drilled in advance for the installation of a member (22) for immobilizing the profile.

L'invention va être exposée de façon plus détaillée à l'aide d'un exemple pratique, illustré à l'aide des dessins parmi lesquels
Fig. 1 est une vue schématique d'ensemble du dispositif et du profilé.The invention will be explained in more detail with the aid of a practical example, illustrated with the aid of the drawings, among which
Fig. 1 is a schematic overview of the device and the profile.

Fig. 2 est une vue de détail, en coupe, du même dispositif. Fig. 2 is a detail view, in section, of the same device.

La figure 1 montre un profilé ou "montant" 1 horizontal, à section en C comprenant une âme 2, une aile horizontale supérieure 3 prolongée par un retour 4 vertical, et une aile horizontale 5 identique à l'aile 3 et également prolongée par un retour 6. La "suspente 7 comprend une semelle horizontale 8 de largeur sensiblement égale à celle des ailes horizontales, ou légèrement supérieure, deux côtés verticaux 9, 10 de hauteur au moins égale à celle de l'âme 2, suivis chacun d'une partie oblique 11, 12 qui fait un angle de 60 à 700 environ avec l'horizontale et est prolongé d'une partie terminale horizontale 13, 14
La figure 2 montre le détail de ces parties terminales. Elles sont percées chacune d'un trou vertical 15, 16 et elles sont superposées, c'est-à-dire que la partie oblique est égarement plus longue que la partie oblique 12.FIG. 1 shows a horizontal section or "upright" 1, with a C section comprising a core 2, an upper horizontal wing 3 extended by a vertical return 4, and a horizontal wing 5 identical to wing 3 and also extended by a back 6. The "hanger 7 comprises a horizontal sole 8 of width substantially equal to that of the horizontal wings, or slightly greater, two vertical sides 9, 10 of height at least equal to that of the core 2, each followed by a oblique part 11, 12 which makes an angle of approximately 60 to 700 with the horizontal and is extended by a horizontal terminal part 13, 14
Figure 2 shows the detail of these terminal parts. They are each pierced with a vertical hole 15, 16 and they are superimposed, that is to say that the oblique part is slightly longer than the oblique part 12.

Les trous 15, 16, qui sont en alignement, sont destinés à être traversés par une tige de soutien 17, filetée, verticale, qui peut elle-même être fixée aux poutres par tous moyens connus : console ou équerre fixée sur la paroi latérale d'une poutre, scellement direct de la tige dans la poutre ou bien dans la face inférieure d'une dalle de béton etc La suspente est fixée sur la tige 17 par un écrou 18 et un contre-écrou 19.The holes 15, 16, which are in alignment, are intended to be crossed by a support rod 17, threaded, vertical, which can itself be fixed to the beams by any known means: console or bracket fixed on the side wall d 'a beam, direct sealing of the rod in the beam or in the underside of a concrete slab etc. The hanger is fixed to the rod 17 by a nut 18 and a lock nut 19.

Sur le côté vertical 9 qui est en contact avec l'âme 2 du profilé, on peut voir deux trous 20, 21. Ces trous sont destinés à livrer passage à une vis autotaraudeuse 22 destinée à être vissée dans l'âme du profilé pour l'immobiliser aprèsbsa mise en place. On a prévu deux trous pourla raison suivante : la normalisation prévoit plusieurs montants dont la section diffère par la hauteur de l'âme 2 alors que la largeur des ailes 3, 5 est la même, par exemple des hauteurs de 70 et 90 mm pour une largeur de 50 mm, ou bien des hauteurs de 48, 70 et 75 mm pour une largeur de 35 mm. La même suspente peut servir pour plusieurs montants de même largeur, si la hauteur des côtés verticaux 9 et 10 est au moins égale à la plus grande des hauteurs des profilés.La présence des deux trous 20, 21 permet dans tous les cas de placer la vis 22 dans la zone centrale de l'âme 2. On the vertical side 9 which is in contact with the core 2 of the profile, one can see two holes 20, 21. These holes are intended to allow passage to a self-tapping screw 22 intended to be screwed into the core of the profile for the 'immobilize after installation. Two holes have been provided for the following reason: the standardization provides for several uprights whose section differs by the height of the core 2 while the width of the wings 3, 5 is the same, for example heights of 70 and 90 mm for a width of 50 mm, or heights of 48, 70 and 75 mm for a width of 35 mm. The same hanger can be used for several uprights of the same width, if the height of the vertical sides 9 and 10 is at least equal to the greatest of the heights of the profiles. The presence of the two holes 20, 21 allows in all cases to place the screw 22 in the central zone of the core 2.

On peut aussi prévoir un trou au milieu de la semelle 8, dans le même but. One can also provide a hole in the middle of the sole 8, for the same purpose.

On observera la grande simplicité d'obtention du dispositif selon l'invention : découpe d'une bande rectangulaire de métal (pratiquement sans perte de matière), perçage des trous 15, 16, 20, 21 et pliage. We observe the great simplicity of obtaining the device according to the invention: cutting a rectangular metal strip (practically without loss of material), drilling holes 15, 16, 20, 21 and folding.

Si on le désire, on peut prévoir une passe d'emboutissage pour former des nervures de renfort. If desired, a drawing pass can be provided to form reinforcing ribs.

L'homme de métier comprendra aisément que la suspente selon l'invention est utilisable pour tous profilés ayant une face inférieur horizontale, par exemple à section rectangulaire fermée ou en L. Those skilled in the art will readily understand that the hanger according to the invention can be used for all profiles having a horizontal lower face, for example with a closed rectangular section or in an L shape.

Dans tous les cas, elle permet d'utiliser au mieux le profilé métallique supportant, par exemple, des plaques de plâtre dans le sens de son inertie maximale, et donc de réduire le nombre de points de suspension du plafo-nd, d'où amélioration de la productivité du montage, tout en maintenant une planéité de l'ouvrage fini (plafond) satisfaisante et conforme à la réglementation en vigueur.  In all cases, it allows the best use of the metal profile supporting, for example, plasterboard in the direction of its maximum inertia, and therefore reducing the number of suspension points of the ceiling, hence improvement of the assembly productivity, while maintaining a flatness of the finished work (ceiling) satisfactory and in accordance with the regulations in force.
