Un plafond suspendu n'a pas de fonction structurelle dans un bâtiment. Il a pour fonctions : A suspended ceiling has no structural function in a building. It has the following functions:
• de dissimuler les éléments techniques alimentant la pièce et/ou le bâtiment, à savoir les divers câbles électriques, les conduites de climatisation, les conduites d'eau, d'air...  • to conceal the technical elements supplying the room and / or the building, namely the various electrical cables, the air conditioning ducts, the water and air ducts, etc.
• de se monter et de se démonter aisément afin de permettre la maintenance de ces différents éléments techniques  • to assemble and dismount easily to allow maintenance of these different technical elements
• d'absorber les bruits, ou plus généralement de corriger l'acoustique d'un espace par absorption ou réflexion des sons, grâce à des qualités acoustiques propres aux matériaux utilisés ou grâce à des perforations ou grâce à des formes  • to absorb noises, or more generally to correct the acoustics of a space by absorption or reflection of the sounds, thanks to the acoustic qualities specific to the materials used or thanks to perforations or thanks to forms
• de réduire la hauteur de plafond pour répondre à des contraintes d'économie de chauffage ou des contraintes esthétiques  • to reduce the ceiling height to meet heating economy constraints or aesthetic constraints
• de réfléchir la lumière  • reflect the light
• d'accepter des accessoires (luminaires, grilles de ventilation, systèmes anti -incendie, détecteurs de fumée...) •  • to accept accessories (lighting fixtures, ventilation grilles, fire prevention systems, smoke detectors ...) •
Un plafond suspendu (ou faux plafond) est, selon la définition usuelle dans le domaine de la construction de bâtiment, un plafond suspendu au moyen d'un système de suspension ou par ossature ou profil de rive fixé directement à une structure d'un bâtiment (structure porteuse telle que toiture, poutre ou murs, ou bien structure de fixation intermédiaire ou bien encore vrai plafond fixé à la structure porteuse) .  A suspended ceiling (or false ceiling) is, according to the usual definition in the field of building construction, a suspended ceiling by means of a suspension system or a skeleton or edge profile directly attached to a structure of a building (load-bearing structure such as roof, beam or walls, or intermediate fixing structure or even ceiling attached to the supporting structure).
Concrètement, un faux plafond est constitué généralement d'une pluralité de dalles plates, de faible épaisseur (de l'ordre de 1 à 3 centimètres) par rapport aux dimensions de leurs faces principales (longueur, largeur de l'ordre de quelques dizaines de centimètres à quelques mètres), dalles positionnées dans un même plan sur une structure support quadrillée fixée à la structure porteuse du bâtiment. Specifically, a false ceiling is generally composed of a plurality of flat slabs, of small thickness (of the order of 1 to 3 centimeters) with respect to the dimensions of their main faces (length, width of the order of a few tens of centimeters to a few meters), slabs positioned in the same plane on a grid support structure attached to the load-bearing structure of the building.
A ce jour, tous les systèmes de pose existants permettent de réaliser des faux plafonds plats, parallèles à la surface horizontale du sol. A titre d'exemple, le document FR 1 424 561 décrit un tel système de fixation de dalles. Le système comprend une pluralité de rails à section en T inversé. Un pied du T rails est destiné à être fixé à la structure porteuse. Les deux branches du T sont destinées à recevoir en appui les bords des dalles, qui sont ensuite immobilisées sur le rail par des ressorts à lames. Les deux branches du T étant planes et parallèles, le faux plafond obtenu est parfaitement plat. To date, all existing installation systems allow for false flat ceilings, parallel to the horizontal surface of the ground. By way of example, document FR 1 424 561 describes such a slab fixing system. The system includes a plurality of inverted T-section rails. One foot of the T rails is intended to be attached to the structure carrier. The two branches of the T are intended to support the edges of the slabs, which are then immobilized on the rail by leaf springs. The two branches of the T being flat and parallel, the false ceiling obtained is perfectly flat.
De nombreux plafonds suspendus horizontaux apportent également des caractéristiques acoustiques d'absorption du son. La correction acoustique consiste à modifier le rendu sonore d'une pièce pour l'adapter à son utilisation. Un taux de d'absorption acoustique aw (Alpha sabine) compris entre 0 et 1 est la valeur caractérisant la performance de cette absorption acoustique (1 étant la valeur optimale). Les solutions les plus courantes sont l'utilisation : Many horizontal suspended ceilings also provide acoustic sound absorption characteristics. Acoustic correction consists of modifying the sound reproduction of a piece to adapt it to its use. An absorption rate aw (alpha sabine) between 0 and 1 is the value characterizing the performance of this acoustic absorption (1 being the optimum value). The most common solutions are the use:
• d'un matériau poreux qui évite la réflexion du son ; mais un tel matériau engendre un surcoût non négligeable · des perforations dans les dalles qui permettent aux bruits de ne pas être réfléchis vers le volume de la pièce ; mais de telles perforations ne permettent pas de correction acoustique, totale ou partielle, par réflexion des sons dans une ou plusieurs directions privilégiées.  • a porous material that avoids sound reflection; but such a material generates a significant additional cost · perforations in the slabs that allow noises not to be reflected towards the volume of the room; but such perforations do not allow acoustic correction, total or partial, by reflection of sounds in one or more privileged directions.
Il existe des lieux où des plafonds suspendus avec des inclinaisons de dalles, ou des plafonds avec des dalles disposées sur des niveaux différents ont été posés pour corriger l'acoustique d'un espace. Ils sont mis en oeuvre par des hommes du métier qui utilisent des systèmes d'accroché filaires où chaque dalle est montée une par une et où les longueurs des accroches sont réglées une à une (comme dans les salles de concert ou de cinéma). Mais il n'est pas commun de monter ce type de plafond car à ce jour, il n'existe pas de dispositif standardisé et prêt à l'emploi pour répondre à ce genre de montage pour des plafonds suspendus. Pourtant il existe un réel intérêt esthétique et technique pour de tels plafonds. There are places where suspended ceilings with sloping slabs, or ceilings with slabs arranged on different levels have been laid to correct the acoustics of a space. They are implemented by those skilled in the art who use wired hanging systems where each slab is mounted one by one and where the lengths of the hooks are set one by one (as in concert halls or movie theaters). But it is not common to mount this type of ceiling because to date, there is no standardized device and ready to use to meet this kind of mounting for suspended ceilings. Yet there is a real aesthetic and technical interest for such ceilings.
Description de l'invention Description of the invention
L'invention propose un nouveau dispositif pour la fixation d'une dalle à une structure, nouveau dispositif qui permet de fixer aisément des dalles à des hauteurs et des inclinaisons variables. The invention proposes a new device for fixing a slab to a structure, a new device that makes it easy to fix slabs at varying heights and inclinations.
Plus précisément, l'invention propose un dispositif pour la fixation d'une dalle à une structure, dispositif comprenant : More specifically, the invention provides a device for fixing a slab to a structure, comprising:
• une suspente composée d'une tige filetée et d'un crochet de sécurité, une première extrémité de la tige filetée étant agencée pour être reliée à la structure, le crochet de sécurité étant solidarisé à une deuxième extrémité de la tige filetée par un système d'écrous,  • A hanger consisting of a threaded rod and a safety hook, a first end of the threaded rod being arranged to be connected to the structure, the safety hook being secured to a second end of the threaded rod by a system nut,
• un tube maintenu dans le crochet de sécurité,  • a tube held in the safety hook,
· un crochet de fixation fixé par une liaison rigide sur une platine, platine agencée pour être fixée sur une face principale de la dalle, le crochet de fixation s'étendant selon une direction sensiblement perpendiculaire à la platine, une extrémité libre du dit crochet de fixation étant conformée pour être posée en appui sur le tube.  A fixing hook fixed by a rigid connection to a plate, platinum arranged to be fixed on a main face of the slab, the fixing hook extending in a direction substantially perpendicular to the plate, a free end of said hook of fixing being shaped to be placed in support on the tube.
Par structure, on entend ici une structure d'un bâtiment telle qu'une structure porteuse (toit, charpente, poutre, murs, etc.), une structure intermédiaire fixée à la structure porteuse et destinée à porter le faux plafond (dans le cas d'un bâtiment de très grande hauteur notamment), ou même un vrai plafond préexistant dans un bâtiment. La face principale de la dalle est naturellement une des faces de grandes dimensions de la dalle, les dalles de plafond suspendues étant généralement planes, de forme parallélépipédique avec une faible épaisseur. Structure means here a structure of a building such as a supporting structure (roof, frame, beam, walls, etc.), an intermediate structure attached to the supporting structure and intended to carry the false ceiling (in the case of a very tall building in particular), or even a real pre-existing ceiling in a building. The main face of the slab is naturally one of the large faces of the slab, suspended ceiling slabs are generally flat, parallelepiped shape with a small thickness.
L'utilisation d'une tige filetée pour réaliser la suspente permet notamment d'ajuster aisément la hauteur du crochet de sécurité, et donc du tube. De plus, chaque crochet de fixation est destiné à être fixé sur une unique dalle de sorte qu'il est possible, notamment en choisissant des crochets de fixation de différentes longueurs et / ou en ajustant la hauteur de chaque crochet de sécurité, de fixer les dalles du faux plafond totalement indépendamment les unes des autres. Ainsi, en générant des ouvertures et des formes originales, le dispositif décrit présentement permet avec des dalles inclinées et/ou disposées sur des niveaux différents de piéger le son dans ces ouvertures pour améliorer l'absorption acoustique de la pièce et / ou de renvoyer le son dans une direction privilégiée pour faire de la correction acoustique. The use of a threaded rod to make the hanger allows in particular to easily adjust the height of the safety hook, and therefore the tube. In addition, each fixing hook is intended to be fixed on a single slab so that it is possible, in particular by choosing fastening hooks of different lengths and / or by adjusting the height of each safety hook, to fix the false ceiling slabs completely independently of each other. Thus, by generating apertures and original shapes, the presently-described device allows with inclined slabs and / or arranged on different levels to trap the sound in these openings to improve the acoustic absorption of the room and / or to return the room. sound in a privileged direction to make acoustic correction.
Enfin, comme expliqué précédemment, les dalles d'un plafond suspendu doivent être démontables afin de permettre la maintenance des éléments techniques situés à l'arrière des dalles. Le dispositif de fixation présenté répond également à cette contrainte. Finally, as explained above, the slabs of a suspended ceiling must be removable to allow maintenance of the technical elements located at the rear of the slabs. The attachment device presented also meets this constraint.
L'invention apporte donc un dispositif de fixation simple et standardisé des dalles d'un faux plafond indépendamment les unes des autres, avec notamment les avantages suivants : The invention therefore provides a simple and standardized fixing device of the slabs of a false ceiling independently of one another, with in particular the following advantages:
• facilité de mise en place de chaque dalle, indépendamment des dalles adjacentes,  • easy installation of each slab, independently of the adjacent slabs,
• possibilité de mettre en place des dalles d'un même plafond suspendu indépendamment les unes des autres dans des positions inclinées différentes et/ou disposées sur des niveaux différents par rapport au niveau du sol, pour générer une absorption acoustique et / ou une réflexion acoustique,  • possibility of placing slabs of the same ceiling suspended independently of each other in different inclined positions and / or arranged on different levels relative to the ground level, to generate acoustic absorption and / or acoustic reflection ,
• facilité de dépose de chaque dalle, indépendamment des dalles adjacentes.  • ease of removal of each slab, regardless of adjacent slabs.
Selon un mode de réalisation, le crochet de fixation présente une partie principale plane s'étendant dans un plan perpendiculaire à la platine ; la partie principale du crochet de fixation s'étend également dans un plan sensiblement perpendiculaire à un axe longitudinal du tube lorsque le crochet de fixation est posé sur le tube ; et l'extrémité du crochet de fixation présente une encoche de formes et de dimensions ajustées à des dimensions associées d'une section du tube pour permettre une rotation libre du crochet autour du tube. According to one embodiment, the fixing hook has a main flat part extending in a plane perpendicular to the plate; the main part of the fixing hook also extends in a plane substantially perpendicular to a longitudinal axis of the tube when the fixing hook is placed on the tube; and the end of the fixing hook has a notch of shapes and dimensions adjusted to associated dimensions of a section of the tube to allow free rotation of the hook around the tube.
Cette forme spécifique de crochet a l'avantage d'être facile à réaliser, par découpage de la forme recherchée dans un matériau plat tel qu'une tôle métallique par exemple. De plus, la forme spécifique de l'encoche de l'extrémité libre du crochet de fixation, en rotation libre autour du tube, facilite la pose ou la dépose d'une dalle, et permet également de positionner aisément une dalle selon une inclinaison souhaitée. Selon un mode de réalisation, la platine comprend au moins un évidement débouchant permettant la fixation de la platine sur la face principale de la dalle par une vis. Ainsi la platine, par définition plane, peut être aisément fixée sur la face principale plane de la dalle. Selon une variante, la face principale de la dalle peut être légèrement creusée localement, d'une épaisseur au moins égale à l'épaisseur de la platine, de sorte que la platine ne dépasse pas de la face principale de la dalle après fixation. Le dispositif selon l'invention peut encore comprendre un rail d'accroché conformé pour être solidarisé à la structure, le rail d'accroché comprenant au moins un évidement débouchant conformé pour recevoir la première extrémité de la tige filetée, le dispositif comprenant également un double écrou pour immobiliser la première extrémité de la tige filetée dans l'évidement du rail d'accroché. Le rail d'accroché facilite la pose des suspentes. Le dispositif selon l'invention peut encore comprendre une entretoise positionnée au dessus dudit crochet de sécurité et accrochée directement à ladite tige filetée par friction, de sorte à permettre de rigidifier l'ensemble du dispositif de fixation et à imposer une distance souhaitée entre les suspentes. This specific form of hook has the advantage of being easy to achieve, by cutting the desired shape in a flat material such as sheet metal for example. In addition, the specific shape of the notch of the free end of the fixing hook, in free rotation around the tube, facilitates the installation or removal of a slab, and also makes it easy to position a slab at a desired inclination . According to one embodiment, the plate comprises at least one opening opening for fixing the plate on the main face of the slab by a screw. Thus the plate, by definition flat, can be easily fixed on the main flat face of the slab. According to one variant, the main face of the slab may be slightly hollowed out locally, with a thickness at least equal to the thickness of the plate, so that the plate does not protrude from the main face of the slab after fixing. The device according to the invention may also comprise a hooked rail shaped to be secured to the structure, the hooked rail comprising at least one opening opening shaped to receive the first end of the threaded rod, the device also comprising a double nut to immobilize the first end of the threaded rod in the recess of the hooked rail. The hooked rail facilitates the installation of the lines. The device according to the invention may also comprise a spacer positioned above said safety hook and hooked directly to said threaded rod by friction, so as to make it possible to stiffen the entire fastening device and to impose a desired distance between the lines .
L'invention concerne également un plafond suspendu à une structure, par exemple une structure porteuse ou une structure intermédiaire d'un bâtiment, plafond suspendu comprenant une pluralité de dalles suspendues par un ou des dispositif(s) de fixation tel que décrit ci-dessus. The invention also relates to a ceiling suspended from a structure, for example a supporting structure or an intermediate structure of a building, suspended ceiling comprising a plurality of slabs suspended by one or more fastening device (s) as described above. .
Les avantages de l'invention sont essentiellement la facilité et la rapidité d'installation (et de démontage) d'un tel faux plafond, dans la mesure où chaque dalle est fixée indépendamment l'une de l'autre. Un autre avantage est la possibilité de transformer très rapidement et très facilement un plafond plat en un plafond en trois dimensions, simplement en remplaçant un ou plusieurs crochets de fixation, ou inversement de transformer un plafond en trois dimensions en un plafond plat, par exemple pour modifier ponctuellement l'acoustique d'un bâtiment. The advantages of the invention are essentially the ease and speed of installation (and disassembly) of such a false ceiling, to the extent that each slab is fixed independently of one another. Another advantage is the possibility of very quickly and easily transforming a flat ceiling into a three-dimensional ceiling, simply by replacing one or more fixing hooks, or conversely to transform a three-dimensional ceiling into a flat ceiling, for example to punctually modify the acoustics of a building.
L'invention concerne également un plafond suspendu à une structure par l'intermédiaire de dispositifs de fixation tels que décrits ci-dessus. Plus précisément, le plafond suspendu comprend : The invention also relates to a ceiling suspended from a structure by means of fixing devices as described above.

• au moins deux suspentes présentant des longueurs différentes et / ou au moins deux crochets de fixation présentant des longueurs différentes de sorte qu'au moins deux dalles s'étendent dans des plans différents.  At least two suspensions having different lengths and / or at least two fixing hooks having different lengths so that at least two slabs extend in different planes.
Ainsi, en choisissant des longueurs de suspentes appropriées et / ou des longueurs de crochets de fixation appropriées, il est possible de réaliser une multitude de plafonds suspendus différents, notamment des plafonds suspendus avec des dalles dans des positions inclinées ou positionnées sur des niveaux différents.

Description de modes de réalisation de l'invention Comme dit précédemment, un dispositif de fixation de dalle selon l'invention comprend essentiellement : DESCRIPTION OF EMBODIMENTS OF THE INVENTION As previously mentioned, a slab fixing device according to the invention essentially comprises:
• une suspente composée d'une tige filetée (6) et d'un crochet de sécurité (7), une première extrémité de la tige filetée étant agencée pour être reliée à la structure, le crochet de sécurité étant solidarisé à une deuxième extrémité de la tige filetée (7) par un système d'écrous (8),  • A hanger consisting of a threaded rod (6) and a safety hook (7), a first end of the threaded rod being arranged to be connected to the structure, the safety hook being secured to a second end of the threaded rod (7) by a system of nuts (8),
• un tube maintenu dans le crochet de sécurité (7),  • a tube held in the safety hook (7),
· un crochet de fixation fixé par une liaison rigide sur une platine, platine agencée pour être fixée sur une face principale de la dalle, le crochet de fixation s'étendant selon une direction sensiblement perpendiculaire à la platine, une extrémité libre du dit crochet de fixation étant conformée pour être posée en appui sur le tube.  A fixing hook fixed by a rigid connection to a plate, platinum arranged to be fixed on a main face of the slab, the fixing hook extending in a direction substantially perpendicular to the plate, a free end of said hook of fixing being shaped to be placed in support on the tube.
Dans un mode de réalisation perfectionné, le dispositif de fixation de dalles est composé d'un ensemble de 5 familles de pièces qui se lient les unes aux autres et permet de répondre ainsi aux contraintes de montage d'un plafond suspendu avec les caractéristiques décrites plus haut (figure 1). In an improved embodiment, the slab fixing device is composed of a set of 5 families of parts that bond to each other and thus meet the mounting constraints of a suspended ceiling with the characteristics described above. top (Figure 1).

• Le tube (3), le goujon (4) et les supports d'extrémités (5)  • The tube (3), the stud (4) and the end supports (5)

• Le rail d'accroché (9) et double écrou (10)  • Hanging rail (9) and double nut (10)

Le dispositif de fixation est décrit ci-dessous en partant de la dalle vers le plafond. The fixing device is described below starting from the slab towards the ceiling.
Sur la dalle (12) de plafond est accrochée la famille de pièces platine (1) et crochet de fixation (2). Les platines sont fixées sur la dalle par l'intermédiaire de vis (13). Un crochet (2) vient se positionner par une liaison rigide dans chaque platine et assure ainsi la mise et le maintien en position du crochet (figure 2a et figure 2b). L'extrémité libre des crochets de fixation (2) vient se poser sur des tubes (3) situés au-dessus et de chaque coté de la dalle (figure 3b), assurant ainsi la mise et le maintien en position de la dalle (12). Cette liaison pivot entre les crochets et les tubes permet de créer l'inclinaison de chaque dalle (figure 3a). Cette inclinaison peut se réaliser en positionnant des crochets de fixation (2) identiques sur des tubes (3) disposés sur des crochets de sécurité (7) de longueurs différentes permettant ainsi de générer des hauteurs différentes de chaque coté de la dalle (figure 4), et / ou en positionnant sur des tubes situés sur une même hauteur des crochets de fixation (2) de dimensions différentes (figure 5). On the ceiling slab (12) hangs the family of platinum parts (1) and fixing hook (2). The plates are fixed on the slab by means of screws (13). A hook (2) is positioned by a rigid connection in each plate and thus ensures the setting and maintaining position of the hook (Figure 2a and Figure 2b). The free end of the fastening hooks (2) is placed on tubes (3) located above and on each side of the slab (Figure 3b), thus ensuring the setting and the holding in position of the slab (12). ). This pivot connection between the hooks and the tubes makes it possible to create the inclination of each slab (FIG. 3a). This inclination can be achieved by positioning identical fastening hooks (2) on tubes (3) arranged on safety hooks (7) of different lengths, thus making it possible to generate different heights on each side of the slab (FIG. 4). , and / or by positioning tubes (2) of different dimensions on the same height of the tubes (FIG. 5).
Le tube (3) est une pièce indispensable au dispositif et joue un rôle majeur dans l'obtention des inclinaisons des dalles et de leur facilité de pose. En effet, la forme arrondie du tube en liaison avec la forme arrondie de l'extrémité libre du crochet de fixation (2) participe à la facilité de pose ces dalles car elle permet de suspendre d'abord un coté de la dalle par deux crochets puis de remonter l'ensemble de la dalle en tournant autour de l'axe du tube déjà sollicité avant de venir poser les deux derniers crochets sur le tube en vis-à-vis (figure 3b). The tube (3) is an indispensable part of the device and plays a major role in obtaining the inclinations of the slabs and their ease of installation. Indeed, the rounded shape of the tube in connection with the rounded shape of the free end of the fixing hook (2) contributes to the ease of laying these slabs because it allows to suspend first one side of the slab by two hooks then reassemble the entire slab by turning around the axis of the already stressed tube before coming to put the last two hooks on the tube vis-à-vis (Figure 3b).
Les plafonds suspendus avec des dalles disposées à des niveaux de hauteurs différentes sont réalisés soit en positionnant des tubes à des hauteurs différentes grâce à des tiges filetées (6) de hauteurs différentes, soit en utilisant des crochets de hauteurs différentes pour chaque dalle (figure 6). Le dispositif permet également de combiner ces deux principes d'accroché. Suspended ceilings with slabs arranged at different heights are made either by positioning tubes at different heights using threaded rods (6) of different heights, or by using hooks of different heights for each slab (Figure 6). ). The device also allows to combine these two principles of hooked.
Afin de réaliser de grandes longueurs de tube, un goujon (4) de liaison peut s'ajouter au dispositif et permettre de lier deux tubes ensemble par une liaison rigide. Des supports d'extrémités (5) permettent de poser et fixer ces tubes sur les murs en leurs extrémités. Le goujon (4) n'est pas nécessaire si un unique tube est utilisé pour réaliser la longueur de tube souhaité. De même, les supports d'extrémité ne sont pas indispensables en l'absence de murs, ou si la rigidité de l'ensemble est suffisante. In order to achieve long lengths of tube, a connecting pin (4) can be added to the device and allow to link two tubes together by a rigid connection. End supports (5) make it possible to place and fix these tubes on the walls at their ends. The stud (4) is not needed if a single tube is used to achieve the desired tube length. Similarly, the end supports are not essential in the absence of walls, or if the rigidity of the assembly is sufficient.
La suspente composée d'une tige filetée (6), d'un crochet de sécurité (7) et d'écrous (8) permet de suspendre les tubes(3). Les crochets de sécurité, fixés chacun au plafond à l'aide d'une tige filetée accueillent les tubes. La liaison entre le crochet et la tige filetée est réalisée par un pas de filetage, ce qui permet des réglages précis grâce aux écrous lors de la pose des dalles (alignement, planéité...). Le tube peut légèrement glisser transversalement su les crochets pour permettre des ajustements. Le ressort anti-retour prévu sur le crochet (7) évite au tube (3) une fois posé dans le crochet de sécurité de ressortir lors des différentes manipulations des dalles, notamment lors d'un démontage de ces dalles (figure 8). The hanger consists of a threaded rod (6), a safety hook (7) and nuts (8) to suspend the tubes (3). The safety hooks, each fixed to the ceiling with a threaded rod, receive the tubes. The connection between the hook and the threaded rod is made by a thread pitch, which allows precise adjustments thanks to the nuts during the laying of the slabs (alignment, flatness ...). The tube may slightly slide transversely on the hooks to allow adjustments. The non-return spring provided on the hook (7) prevents the tube (3) once installed in the safety hook to come out during the various manipulations of the slabs, in particular during disassembly of these slabs (Figure 8).
La tige filetée (6) est elle-même suspendue au plafond soit sur le rail d'accroché (9) par un système de double écrous, soit directement dans la structure du plafond (béton, bois, ossature primaire...). Le double écrou permet de réaliser des réglages de niveau grossier entre le plafond et les dalles (et de compenser les irrégularités du plafond), les écrous (8) sur le crochet de sécurité permettant de finaliser précisément ces réglages (figure 9a). The threaded rod (6) is itself suspended from the ceiling either on the hook rail (9) by a system of double nuts, or directly in the ceiling structure (concrete, wood, primary frame ...). The double nut makes it possible to make coarse level adjustments between the ceiling and the slabs (and to compensate for the irregularities of the ceiling), the nuts (8) on the safety hook making it possible to finalize precisely these adjustments (figure 9a).
Les rails d'accroché (9) facilitent la pose des suspentes. En effet, pour fixer rapidement l'ensemble des suspentes suivant le montage de chaque plafond, le rail d'accroché permet de disposer de repères visuels au plafond. Ils servent également de guide pour réaliser les perforations qui les maintiennent. Ils facilitent la visualisation des zones de difficultés (manque de planéité, de matière...) en permettant de fixer la tige filetée (6) de la suspente directement à la structure du bâtiment. Ils assurent le respect au plus juste des distances nécessaires entre les suspentes (figure 9b). Les rails d'accroché ne sont toutefois pas indispensables ; les suspentes peuvent également être fixées directement sur la structure. Les entretoises (11) se positionnent au-dessus des crochets de sécurité. Elles comportent une série d'encoches, réparties le long des entretoises, dans lesquelles les tiges filetées des suspentes peuvent être insérées à force. Les entretoises s'accrochent ainsi directement aux tiges filetées par friction (figure 10). Elles permettent de rigidifier l'ensemble du dispositif de fixation en créant un quadrillage qui impose définitivement les distances entre tiges filetées (6), notamment lorsque celles-ci sont longues (longueur de 2 mètres au plus, limite généralement imposé par les normes de sécurité dans le bâtiment). Elles sont fixées à leurs extrémités aux murs et peuvent également être utilisées comme support de matériels légers (isolant...). Les entretoises ne sont toutefois pas indispensables, notamment dans le cas où l'assemblage des suspentes et des tubes est suffisamment rigide pour l'application envisagée. The hooked rails (9) facilitate the installation of the lines. Indeed, to quickly fix all the lines following the mounting of each ceiling, the hooked rail provides visual cues to the ceiling. They also serve as a guide to achieve the perforations that maintain them. They facilitate the visualization of areas of difficulty (lack of flatness, material ...) by allowing to fix the threaded rod (6) of the hanger directly to the structure of the building. They ensure the most accurate respect of the necessary distances between the lines (Figure 9b). Hooked rails are not essential; the lines can also be attached directly to the structure. The spacers (11) are positioned above the safety hooks. They comprise a series of notches, distributed along the spacers, in which the threaded rods of the lines can be inserted by force. The Spacers thus cling directly to the threaded rods by friction (Figure 10). They make it possible to stiffen the entire fastening device by creating a grid that definitely imposes the distances between threaded rods (6), especially when they are long (length of 2 meters at the most, the limit generally imposed by the safety standards in the building). They are fixed at their ends to the walls and can also be used as a support for light equipment (insulation ...). Spacers are however not essential, especially in the case where the assembly of the lines and tubes is sufficiently rigid for the intended application.
La figure 1 représente en vue général le dispositif de l'invention avec l'ensemble des pièces mises en place. Les rails d'accroché (9) sont fixés au plafond du bâtiment, les tiges filetées (6) sont maintenues par un double écrous (10) à ces rails. Les crochets de sécurité (7) fixés par deux écrous (8) à la tige filetée (6) permettent de positionner les tubes (3) suivant le plan de montage du plafond. Les dalles (12) s'accrochent à ces tubes à l'aide de crochets (2) eux- mêmes fixés à la dalle à l'aide de platines (1). Figure 1 shows a general view of the device of the invention with all the parts in place. The hooked rails (9) are fixed to the ceiling of the building, the threaded rods (6) are held by a double nut (10) to these rails. The safety hooks (7) fixed by two nuts (8) to the threaded rod (6) position the tubes (3) according to the ceiling mounting plan. The slabs (12) cling to these tubes using hooks (2) themselves fixed to the slab using plates (1).
Les figure 2a et 2b représentent un exemple de platine (1) maintenue par une vis (13) sur une dalle, et un exemple de crochet (2) qui permettent ensemble de réaliser la liaison entre la dalle (12) et le tube (3), et qui permettent notamment l'inclinaison de la dalle et / ou le positionnement dans un plan différent du plan d'une dalle adjacente. La platine 1 est une plaque , par exemple découpée dans une tôle de faible épaisseur (1 à 3 millimètres par exemple), fixée à plat dans la face principale des dalles par une ou plusieurs vis (13). Dans l'exemple représenté, un évidement d'au moins la même épaisseur est prévu dans la face principale des dalles, de sorte que la platine ne dépasse pas de la face principale de la dalle. Ceci facilite notamment l'empilement et le stockage des dalles l'une contre l'autre avant utilisation. Le crochet 2 est également découpé dans une plaque de faible épaisseur (1 à 3 millimètres par exemple). Le crochet comprend une extrémité libre dont la découpe intérieure (21) est adaptée au diamètre des tubes (3) pour permettre une rotation autour des tubes mais sans jeu excessif. Par sa forme, l'extrémité libre du crochet contribue à générer la liaison pivot avec le tube (3) et à faciliter la pose, ainsi que le démontage si nécessaire. Le crochet comprend également une deuxième extrémité dite de verrouillage, terminée par un pied plié à angle droit par rapport à l'axe du crochet et présentant deux ailettes (22, 23). La platine comprend deux ailettes creuses 24, 25, de mêmes diamètres que les ailettes du pied du crochet. Le crochet est solidarisé de la platine de la manière suivante : le pied du crochet est inséré dans les ailettes creuses de la platine, puis les ailettes du pied du crochet sont déplacées par une rotation du crochet vers l'intérieur des ailettes creuses 24, 25 de la platine où les ailettes 22, 23 du pied du crochet sont mécaniquement immobilisées dans les ailettes creuses 24, 25 de la platine. Le crochet peut être déverrouillé et enlevé simplement par une rotation inverse. Ce mode de réalisation de la platine et du crochet est avantageux car : FIGS. 2a and 2b show an example of a plate (1) held by a screw (13) on a slab, and an example of a hook (2) which together enable the slab (12) to be connected to the tube (3). ), and which allow in particular the inclination of the slab and / or the positioning in a different plane of the plane of an adjacent slab. The plate 1 is a plate, for example cut from a sheet of thin thickness (1 to 3 millimeters for example), fixed flat in the main face of the slabs by one or more screws (13). In the example shown, a recess of at least the same thickness is provided in the main face of the slabs, so that the plate does not exceed the main face of the slab. This facilitates in particular the stacking and storage of the slabs against each other before use. The hook 2 is also cut in a thin plate (1 to 3 millimeters for example). The hook comprises a free end whose inner cutout (21) is adapted to the diameter of the tubes (3) to allow rotation around the tubes but without excessive play. By its shape, the free end of the hook contributes to generating the pivot connection with the tube (3) and to facilitate the installation, as well as disassembly if necessary. The hook also comprises a second end called locking, terminated by a foot bent at right angles to the axis of the hook and having two fins (22, 23). The plate comprises two hollow fins 24, 25, of the same diameter as the fins of the foot of the hook. The hook is secured to the plate in the following manner: the foot of the hook is inserted into the hollow fins of the plate, then the fins of the foot of the hook are moved by a rotation of the hook towards the inside of the hollow fins 24, 25 the plate where the fins 22, 23 of the foot of the hook are mechanically immobilized in the hollow fins 24, 25 of the plate. The hook can be unlocked and removed simply by reverse rotation. This embodiment of the plate and the hook is advantageous because:
• les platines peuvent être fixées sur les dalles bien en amont, par exemple en usine lors de la fabrication des dalles,  • the plates can be fixed on the slabs well upstream, for example at the factory during the manufacture of slabs,
· les dalles et les crochets peuvent être stockés indépendamment les uns des autres, et leurs formes plates facilitent le stockage,  · Slabs and hooks can be stored independently of each other, and their flat shapes facilitate storage,
• le montage des crochets est très simple et très rapide, et peut être effectué au dernier moment, lors de la pose du faux plafond. La figure 3a montre l'agencement du dispositif au niveau du crochet (2), du tube (3) et du crochet de sécurité (7) : la forme du crochet (2) permet une liaison pivot sur le tube (3), ce qui facilite le montage (et démontage des dalles) car il se fait en deux temps comme le montre le figure 3b. La figure 4 et la figure 5 présentent deux modèles de montage possibles de plafond suspendu avec des dalles inclinées. La figure 6 et la figure 7 présentent deux autres modèles de montages possibles de plafond suspendu avec des dalles disposées cette fois à des niveaux différents. Les figures 4 à 7 mettent en avant la multitude de montages de plafond que le dispositif permet de réaliser à partir de notre dispositif standardisé. La figure 8 représente un modèle de suspente avec son crochet de sécurité (7), son principe anti-retour (7a) qui garantit le maintien du tube dans le crochet notamment au démontage des dalles et les écrous de réglage (8). La figure 9a représente le dispositif d'accroché au plafond avec ses systèmes de réglages à deux niveaux. La figure 9b est un exemple de modèle de rail d'accroché. • the mounting of the hooks is very simple and very fast, and can be done at the last moment, when installing the false ceiling. FIG. 3a shows the arrangement of the device at the level of the hook (2), the tube (3) and the safety hook (7): the shape of the hook (2) allows a pivot connection on the tube (3); which facilitates the assembly (and disassembly of slabs) because it is done in two stages as shown in Figure 3b. Figure 4 and Figure 5 present two possible mounting models of suspended ceiling with inclined slabs. Figure 6 and Figure 7 show two other models of possible suspended ceiling mountings with slabs, this time arranged at different levels. Figures 4 to 7 highlight the multitude of ceiling mountings that the device can achieve from our standardized device. 8 shows a suspension model with its safety hook (7), its non-return principle (7a) which ensures the maintenance of the tube in the hook including disassembly of slabs and adjusting nuts (8). Figure 9a shows the ceiling-hanging device with its two-level adjustment systems. Figure 9b is an example of a hanging rail model.
La figure 10 représente l'entretoise (11) qui permet de rigidifier l'ensemble du dispositif et peut supporter du matériel léger. Figure 10 shows the spacer (11) which stiffens the entire device and can support light equipment.
