ARRIERE-PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Depuis de nombreuses années, les techniques propres au métier du bâtiment ont beaucoup évolué pour permettre la rationalisation des tâches, la diminution des temps de main-d'oeuvre et dès lors des coûts, une élimination des défauts apparaissant dans le temps, une amélioration des qualités phoniques, thermiques et de protection contre l'incendie ainsi qu'un embellissement de l'esthétique finale.For many years, the techniques specific to the building trade have evolved a lot to allow the rationalization of tasks, the reduction of labor time and therefore costs, the elimination of faults appearing over time, an improvement in phonic, thermal and fire protection qualities as well as an embellishment of the final aesthetic.

C'est ainsi que dans le domaine de la réhabilitation des immeubles anciens ou dans celui des constructions nouvelles dont les planchers sont des dalles de béton armé, coulées "in-situ" ou encore des dalles résultant de la combinaison de poutrelles, de hourdis et d'une chape de béton, il est devenu fréquent de placer au-dessous des dalles ainsi formées des plafonds suspendus par l'intermédiaire de points d'ancrage situés dans les poutres, dans les charpentes ou dans les dalles de planchers, afin de créer sous ces dalles de niveau un espace technique pour l'isolation thermique ou phonique, le passage de gaines techniques (ventilation, chauffage, câbles électriques, protection incendie) ou autres éléments.Thus in the field of the rehabilitation of old buildings or in that of new constructions whose floors are reinforced concrete slabs, poured "in situ" or slabs resulting from the combination of beams, slabs and of a concrete screed, it has become common to place suspended ceilings below the slabs thus formed by means of anchor points located in the beams, in the frames or in the floor slabs, in order to create under these level slabs a technical space for thermal or sound insulation, the passage of technical ducts (ventilation, heating, electric cables, fire protection) or other elements.

Les réalisations les plus récentes de tels plafonds suspendus consistent en une ossature généralement métallique suspendue à des points d'ancrage sur laquelle sont rapportés des éléments de remplissage (dalles, plaques, panneaux ou autres) formant la surface du plafond souhaité.The most recent embodiments of such suspended ceilings consist of a generally metallic framework suspended from anchor points on which are attached filling elements (slabs, plates, panels or the like) forming the surface of the desired ceiling.

L'ossature à laquelle sont assujettis les éléments de remplissage résulte généralement d'un montage sur chantier de fourrures dont les positions relatives créent :

  • - soit une structure simple, appelée structure primaire quand les fourrures la constituant sont placées parallèlement entre elles et qu'elles se situent toutes dans un seul plan,
  • - soit une structure complexe composée d'une structure primaire telle que précitée et d'une structure secondaire, cette dernière étant formée de fourrures parallèles entre elles mais disposées orthogonalement par rapport à celles de la structure primaire, dans le même plan ou dans des plans différents.
The framework to which the filling elements are subjected generally results from a mounting on site of furs whose relative positions create:
  • - either a simple structure, called the primary structure when the furs constituting it are placed parallel to each other and when they are all in one plane,
  • - Or a complex structure composed of a primary structure as mentioned above and a secondary structure, the latter being formed of furs parallel to each other but arranged orthogonally to those of the primary structure, in the same plane or in planes different.

Ces structures primaire et secondaire, qui sont assujetties l'une à l'autre par des moyens appropriés, interviennent chacune selon une fonction spécifique:

  • - la première structure, encore appelée structure primaire, dotée de moyens de suspension réglables en hauteur, est la partie de l'ossature qui permet de la suspendre, une fois formée, aux divers points d'ancrage et de franchir des portées très importantes avec un nombre de points d'ancrage limité ;
  • - la deuxième structure, dont les fourrures sont placées orthogonalement à celles de la première structure, permet de rigidifier ladite première structure en lui donnant une cohésion mécanique et de créer au sein de l'ossature des intervalles réguliers entre les fourrures. Cette deuxième structure devient le support plan sur lequel sont rapportés les éléments de remplissage constituant le plafond.
These primary and secondary structures, which are subject to each other by appropriate means, each operate according to a specific function:
  • - the first structure, also called primary structure, with suspension means adjustable in height, is the part of the framework which allows it to be suspended, once formed, at the various anchor points and to cross very large spans with a limited number of anchor points;
  • - The second structure, the furs of which are placed orthogonally to those of the first structure, makes it possible to stiffen said first structure by giving it mechanical cohesion and to create regular intervals between the furs within the framework. This second structure becomes the flat support on which the filling elements constituting the ceiling are attached.

Les raisons qui ont présidé à la création de telles ossatures sont nombreuses et importantes:

  • L'une de ces raisons procède, au moins pour partie, de l'industrialisation du bâtiment par la préfabrication en atelier d'éléments intervenant dans la construction. En effet, l'apparition sur le marché de produits semi-finis et finis tels que panneaux, plaques, dalles, carreaux ou autres, prêts à l'emploi, est une forte incitation à leur exploitation, car elle génère, par un phénomène de masse, une normalisation des produits, une réduction des coûts de fabrication et une diminution importante des temps de montage sur chantier.
There are many and important reasons for the creation of such frames:
  • One of these reasons comes, at least in part, from the industrialization of the building by the prefabrication in the workshop of elements involved in construction. Indeed, the appearance on the market of semi-finished and finished products such as panels, plates, slabs, tiles or other, ready to use, is a strong incentive to their exploitation, because it generates, by a phenomenon of mass, standardization of products, reduction in manufacturing costs and a significant reduction in assembly times on site.

Une autre de ces raisons résulte de la nécessité de franchir de très grandes portées et/ou de limiter le nombre de points d'ancrage d'une telle ossature afin de réduire le nombre de réglages à effectuer, d'améliorer l'esthétique et de limiter les coûts.Another of these reasons results from the need to cross very large spans and / or to limit the number of anchoring points of such a framework in order to reduce the number of adjustments to be made, to improve the aesthetics and to limit costs.

Les autres raisons découlent naturellement des précédentes car il est évident que :

  • - l'exploitation de ces produits industriels dans la réalisation de plafonds suspendus exige une ossature suffisamment rigide et mécaniquement résistante pour leur servir de support,
  • - une ossature ne peut être attrayante pour l'homme de métier que si elle consiste en un système mécanique simple et robuste dont les divers éléments de charpente et de liaison préfabriqués peuvent être associés facilement les uns aux autres sur chantier de telle sorte que leur assemblage et leur désassemblage puisse se faire rapidement sans outillage spécial,
  • - l'ossature en cours d'assemblage doit être facilement arrimée aux points d'ancrage,
  • - l'horizontalité de l'ossature arrimée ou en cours d'image doit être facilement acquise,
  • - le plafond suspendu, une fois les panneaux montés sur l'ossature, doit résister aux contraintes mécaniques (mouvement et déformation du gros-oeuvre) se manifestant habituellement par l'inesthétique apparition de fissures, fentes ou encore écailles.
The other reasons follow naturally from the previous ones because it is obvious that:
  • - the exploitation of these industrial products in the production of suspended ceilings requires a framework sufficiently rigid and mechanically resistant to serve as a support,
  • - a frame can only be attractive to those skilled in the art if it consists of a simple and robust mechanical system including the various structural and connecting elements manufactured can be easily associated with each other on site so that their assembly and disassembly can be done quickly without special tools,
  • - the framework being assembled must be easily stowed at the anchor points,
  • - the horizontality of the frame stowed or being imaged must be easily acquired,
  • - the suspended ceiling, once the panels have been mounted on the framework, must resist mechanical stresses (movement and deformation of the shell) usually manifested by the unsightly appearance of cracks, cracks or even scales.

Plusieurs types d'ossatures pour plafonds suspendus sont proposés dans la littérature spécialisée, les unes ne comportant qu'une structure primaire (du premier type), les autres une structure complexe (du deuxième type) comportant deux structures primaire et secondaire croisées.Several types of framework for suspended ceilings are proposed in the specialized literature, some comprising only a primary structure (of the first type), the others a complex structure (of the second type) comprising two crossed primary and secondary structures.

Selon un premier type, l'ossature est formée d'une structure métallique unique, appelée structure primaire (brevets FR 1 216 198 - US 3,835,614 - US,4,364,215 et FR 1 388 940) constituée par des fourrures ou des profilés de section très diverses, en I, en T, en U ou en C, disposant d'une partie médiane et de semelles ou d'ailes le long des bords de cette partie médiane.According to a first type, the framework is formed of a single metallic structure, called primary structure (patents FR 1,216,198 - US 3,835,614 - US, 4,364,215 and FR 1,388,940) constituted by furs or profiles of very diverse section , in I, in T, in U or in C, having a median part and soles or wings along the edges of this median part.

Ces fourrures placées parallèlement les unes aux autres sont suspendues aux points d'ancrage par l'intermédiaire de moyens de préhension tels que des étriers par exemple, et des moyens de suspension tels que des fils métalliques, des tiges filetées ou autres moyens connus, pour y être fixées à la hauteur souhaitée.These furs placed parallel to each other are suspended from the anchoring points by means of gripping means such as stirrups for example, and suspension means such as metal wires, threaded rods or other known means, for be fixed at the desired height.

En outre, ces fourrures peuvent être montées :

  • - sans lien entre elles (brevet FR 1 216 198) à des distances adaptées à la mise en place des plaques, dalles et/ou panneaux propres à la réalisation du plafond suspendu,
  • - ou bien en étant rigidement reliées entre elles par des éléments mécaniques transversaux ou entretoises (brevets US 3,835,614 - US 4,364,215 - FR 1 388 940 et FR 2 646 679) d'une longueur telle que ces éléments placent lesdites fourrures à la distance nécessaire pour l'implantation des plaques, dalles ou panneaux précités.
In addition, these furs can be fitted:
  • - without link between them (patent FR 1 216 198) at distances suitable for the installation of plates, slabs and / or panels suitable for the production of the suspended ceiling,
  • - or by being rigidly connected to each other by transverse mechanical elements or spacers (US patents 3,835,614 - US 4,364,215 - FR 1 388 940 and FR 2 646 679) of a length such that these elements place said furs at the distance necessary for the installation of the aforementioned plates, slabs or panels.

Toutefois, ce type d'ossature suspendue à structure simple (ou encore structure primaire) apparaît comme une première étape d'améliorations acquises, mais reste une proposition insuffisante car :

  • - si par quelques aspects, elle répond à certaines préoccupations de l'homme de métier parce que permettant par exemple le montage "in situ" de l'ossature à partir de systèmes mécaniques préfabriqués à assembler ou encore l'exploitation de plaques, dalles normalisées, préfabriquées pour le remplissage de l'ossature,
  • - par d'autres aspects, elle ne peut répondre à des exigences plus importantes, puisque ce type d'ossature est souvent long à assembler, oblige à de très nombreux et très coûteux réglages pour aboutir à une horizontalité et une planéité du plafond souvent imparfaites, surtout quand l'ossature concerne de grandes portées et quand elle n'empêche pas l'apparition de défauts redhibitoires tels que des fissures ou fentes qui manifestent par leur présence une insuffisance de cohésion, de rigidité et de résistance mécanique pour ce type d'ossatures.
However, this type of suspended structure with simple structure (or even primary structure) appears to be a first step in acquired improvements, but remains an insufficient proposal because:
  • - if by some aspects, it responds to certain concerns of those skilled in the art because, for example, allowing the "in situ" mounting of the framework from prefabricated mechanical systems to be assembled or even the exploitation of plates, standardized slabs , prefabricated for filling the frame,
  • - in other respects, it cannot meet more important requirements, since this type of framework is often long to assemble, requires very many and very costly adjustments to result in horizontality and flatness of the ceiling, which are often imperfect. , especially when the framework concerns large spans and when it does not prevent the appearance of prohibitive defects such as cracks or slots which manifest by their presence an insufficient cohesion, rigidity and mechanical strength for this type of frameworks.

Selon un deuxième type, l'ossature est formée de deux structures différentes (l'une primaire et l'autre secondaire) croisées orthogonalement et rendues solidaires l'une de l'autre par des moyens mécaniques appropriés.According to a second type, the framework is formed of two different structures (one primary and the other secondary) crossed orthogonally and made integral with one another by appropriate mechanical means.

Par opposition au premier type d'ossature dans laquelle l'unique structure est formée de profilés ou fourrures montés en parallèle et maintenus à la distance souhaitée par des entretoises, le deuxième type d'ossature est obtenu par le croisement orthogonal, dans un même plan ou dans des plans différents, des deux structures précitées, l'une et l'autre étant formées par des réseaux de profilés et/ou de fourrures parallèles (brevets FR 2 546 936 - EP 0 004 603 - FR 2 578 570 - US 3,031,042 et DE 1 484 028) dans un même pas ou un pas différent.In contrast to the first type of framework in which the single structure is formed of profiles or furring strips mounted in parallel and maintained at the desired distance by spacers, the second type of framework is obtained by orthogonal crossing, in the same plane or in different planes, of the two aforementioned structures, both of which are formed by networks of profiles and / or parallel furs (patents FR 2 546 936 - EP 0 004 603 - FR 2 578 570 - US 3,031,042 and DE 1,484,028) in the same or a different step.

Ces deux structures

  • - dont l'une, la structure primaire, a pourfonction d'être suspendue à la dalle de niveau par des points d'ancrage (en nombre inférieur à celui développé dans les ossatures du premier type)
  • - et l'autre, la structure secondaire, a pour fonction de recevoir les plaques et panneaux permettant de réaliser le plafond en cachant la dalle de niveau,
These two structures
  • - one of which, the primary structure, has the function of being suspended from the level slab by anchor points (fewer in number than that developed in the frames of the first type)
  • - and the other, the secondary structure, has the function of receiving the plates and panels allowing the ceiling to be produced by hiding the level slab,

sont assujetties l'une à l'autre par des pièces mécaniques de liaison en donnant une ossature plus cohérente, plus rigide et/ou plus robuste que celle du premier type.are secured to each other by mechanical connecting parts giving a more coherent, more rigid and / or more robust framework than that of the first type.

Un tel type d'ossature poursuit les buts de couvrir plus facilement encore de grandes portées et de réduire le nombre de points d'ancrage et dès lors le nombre de réglages des niveaux.Such a type of framework pursues the aims of still more easily covering large spans and of reducing the number of anchoring points and therefore the number of level adjustments.

Le croisement orthogonal dans un même plan des deux structures primaire et secondaire de l'ossature est illustré par le brevet FR 2 578 570. Un tel croisement peut être obtenu quand :

  • - la structure primaire est formée d'un réseau de fourrures parallèles, d'un profil en dont les semelles inférieures, horizontales et les parties médianes verticales sont découpées de proche en proche selon des entailles permettant la mise en place par encliquetage des fourrures de l'autre structure,
  • - la structure secondaire est réalisée grâce à des fourrures d'un profil en C dont les ailes sont retournées vers l'intérieur afin de glisser et de s'encliqueter dans les entailles de la structure primaire.
The orthogonal crossing in the same plane of the two primary and secondary structures of the framework is illustrated by patent FR 2 578 570. Such a crossing can be obtained when:
  • - the primary structure is formed of a network of parallel furs, of a profile in which the lower, horizontal flanges and the vertical median parts are cut step by step according to notches allowing the positioning by clipping of the furs from the other structure,
  • - The secondary structure is made using furs with a C profile, the wings of which are turned inward in order to slide and snap into the notches of the primary structure.

Bien que le croisement dans un même plan des structures primaire et secondaire permette de faire porter les panneaux et/ou plaques du plafond sur l'ensemble des fourrures de l'une et l'autre structure, cette ossature présente des désavantages liés à sa conception, dont certains sont évoqués ci-après :

  • - le renforcement obligé des fourrures de la structure primaire en raison de la présence des multiples entailles qui les fragilisent mécaniquement,
  • - le coût élevé de fabrication desdites fourrures en raison des multiples opérations de formage, d'usinage et de découpe qu'elles doivent subir pour leur réalisation,
  • - l'obligation de préfabriquer des structures primaires comportant des entailles de pas adapté à la dimension des plaques et/ou panneaux utilisés pour la réalisation du plafond,
  • - la nécessité de disposer en stock d'une gamme de structures primaires, chaque structure ayant un pas particulier, de telle sorte que la gamme puisse répondre aux types de pas exigés par les chantiers,
  • - enfin, l'impossibilité d'effectuer un changement d'entraxe ou un déplacement des fourrures secondaires, les structures primaires ayant chacune un pas figé pour chaque entraxe recherché.
Although the crossing in the same plane of the primary and secondary structures allows to carry the panels and / or ceiling plates on all the furs of one and the other structure, this frame has disadvantages related to its design , some of which are discussed below:
  • - the compulsory reinforcement of the furs of the primary structure due to the presence of multiple notches which weaken them mechanically,
  • the high cost of manufacturing said furs due to the multiple forming, machining and cutting operations which they must undergo for their production,
  • - the obligation to prefabricate primary structures comprising notches adapted to the size of the plates and / or panels used for the realization of the ceiling,
  • - the need to have in stock a range of primary structures, each structure having a particular pitch, so that the range can meet the types of pitch required by the sites,
  • - Finally, the impossibility of carrying out a change in center distance or a displacement of the secondary furs, the primary structures each having a fixed pitch for each desired center distance.

Quant au croisement orthogonal dans deux plans différents des deux structures primaire et secondaire, il est illustré par les brevets FR 2 546 939 et EP 0 004 603.As for the orthogonal crossing in two different planes of the two primary and secondary structures, it is illustrated by the patents FR 2 546 939 and EP 0 004 603.

Dans le cas du brevet FR 2 546 939, les structures primaire et secondaire sont constituées par des réseaux de fourrures parallèles se croisant orthogonalement dans deux plans distincts, lesdites fourrures ayant un profil en U dont les ailes sont munies de retours orthogonaux dirigés vers leur intérieur.In the case of patent FR 2 546 939, the primary and secondary structures are constituted by networks of parallel furs crossing orthogonally in two distinct planes, said furs having a U-shaped profile whose wings are provided with orthogonal returns directed towards their interior .

L'objet revendiqué est une pièce mécanique en forme de plaque permettant la liaison 2 à 2 des fourrures des deux structures ainsi que la suspension de l'ossature formée à un plancher ou à une dalle.The claimed object is a mechanical piece in the form of a plate allowing the connection 2 to 2 of the furs of the two structures as well as the suspension of the framework formed on a floor or a slab.

Cette pièce de liaison et éventuellement de suspension, pour des fourrures à fixer croisées en superposition, comporte d'une part, dans son axe longitudinal, une paire de pattes en saillie disposées en opposition, permettant par une rotation d'un quart de tour son accrochage sur la fourrure supérieure et d'autre part, à son extrémité inférieure, un moyen d'encliquetage permettant l'accrochage sur elle de la fourrure inférieure dans une position orthogonale.This connecting piece and possibly of suspension, for furs to be fixed crossed in superposition, comprises on the one hand, in its longitudinal axis, a pair of projecting legs arranged in opposition, allowing by a rotation of a quarter turn its hooking on the upper fur and on the other hand, at its lower end, a latching means allowing the hooking of the lower fur in an orthogonal position.

De plus, à cette pièce de liaison peut être associée une pièce de suspension auxiliaire ayant la forme d'un étrier comportant une base (assurant un montage quart de tour sur la pièce de liaison) et deux ailes élastiquement déformables, comportant chacune un orifice de contour circulaire, permettant par leur rapprochement, leur engagement dans une tige- suspente solidaire d'un point d'ancrage et par leur relâchement, le bloquage de l'ossature dans la position souhaitée.In addition, this connecting piece can be associated with an auxiliary suspension piece in the form of a stirrup comprising a base (ensuring quarter-turn mounting on the connecting piece) and two elastically deformable wings, each comprising a orifice circular outline, allowing by their approximation, their engagement in a suspension rod secured to an anchor point and by their relaxation, the blocking of the frame in the desired position.

Dans le cas du brevet EP 004 603, les structures primaire et secondaire sont également constituées par des réseaux de fourrures parallèles se croisant orthogonalement dans deux plans distincts, lesdites fourrures ayant, pour au moins l'une d'entre elles, un profil en U dont les ailes sont recourbées en oblique vers l'intérieur le long des bords longitudinaux. L'objet de la description est un dispositif de liaison à placer entre deux fourrures croisées orthogonalement.In the case of patent EP 004 603, the primary and secondary structures also consist of networks of parallel furrows intersecting orthogonally in two distinct planes, said furs having, for at least one of them, a U-shaped profile the wings of which are curved obliquely inwards along the longitudinal edges. The object of the description is a connecting device to be placed between two orthogonally crossed furs.

Selon un premier mode, le dispositif de liaison est un étrier en forme de U embrassant la fourrure supérieure et s'encliquetant dans la fourrure inférieure croisée par l'intermédiaire de moyens d'encliquetage présents à chaque extrémité de ses ailes.According to a first embodiment, the connection device is a U-shaped stirrup embracing the upper fur and snapping into the lower cross fur by means of latching means present at each end of its wings.

Selon un deuxième mode, le dispositif de liaison destiné à relier deux fourrures croisées dans deux plans distincts ayant des profils en U (repliés en oblique vers l'intérieur sur leurs bords longitudinaux) est un étrier comprenant un fond et quatre ailes qui sont repliées par paire, dans des directions opposées, à partir des bords se faisant face, l'extrémité des ailes étant pourvue de moyens d'encliquetage leur permettant de s'encliqueter par paire dans les fourrures.According to a second embodiment, the connecting device intended to connect two crossed furs in two distinct planes having U-shaped profiles (folded obliquely inwards on their longitudinal edges) is a stirrup comprising a bottom and four wings which are folded by pair, in opposite directions, from the edges facing each other, the end of the wings being provided with latching means allowing them to snap in pairs in the furs.

Ce type d'ossature à deux structures croisées dans des plans différents apporte des avantages par comparaison avec les types d'ossature précédemment évoqués, en particulier par le fait que :

  • - le renforcement des fourrures de la structure primaire n'est pas nécessaire, puisque elles sont exemptes d'entailles à l'origine de leur affaiblissement mécanique,
  • - les structures primaire et secondaire de l'ossature prennent un caractère plus universel grâce aux dispositifs de liaison qui ne figent pas leur position relative croisée, c'est-à-dire la valeur du pas.
This type of frame with two structures crossed in different planes brings advantages by comparison with the types of frame previously mentioned, in particular by the fact that:
  • - the reinforcement of the furs of the primary structure is not necessary, since they are free from nicks at the origin of their mechanical weakening,
  • - the primary and secondary structures of the framework take on a more universal character thanks to the connection devices which do not freeze their crossed relative position, that is to say the value of the pitch.

Toutefois, ce type d'ossature présente encore des désavantages particulièrement gênants, dont certains sont évoqués ci-après :

  • Un premier désavantage se manifeste dans le fait qu'en l'absence d'un moyen de préréglage du pas intégré à la structure qui permettrait, lors du montage, le choix dans une large gamme du pas à utiliser, le montage du dispositif de liaison entre les fourrures exige l'utilisation sur chantier de pièces de calage pour créer le pas souhaité entre les fourrures. Dans le cas particulier où les dispositifs de suspension de l'ossature et de liaison entre les fourrures des structures primaire et secondaire sont solidaires l'un de l'autre en formant une pièce commune de liaison et de suspension (brevet FR 2 546 939), la position de ladite pièce peut assujettir le pas aux points d'ancrage et dès lors, provoquer un pas de montage non souhaité.
However, this type of frame still has particularly annoying disadvantages, some of which are mentioned below:
  • A first disadvantage manifests itself in the fact that in the absence of a means for presetting the pitch integrated into the structure which would allow, during assembly, the choice in a wide range of the pitch to be used, the mounting of the connection device. between the furs requires the use on site of wedging pieces to create the desired pitch between the furs. In the particular case where the framework suspension devices and connection between the furs of the struc primary and secondary tures are integral with each other by forming a common connecting and suspension part (patent FR 2 546 939), the position of said part can subject the pitch to the anchoring points and therefore cause an undesirable mounting step.

Un autre désavantage apparaît dans la génération de phénomènes acoustiques gênants provoqués par les frottements pièce sur pièce quand les moyens de liaison ne sont pas suffisamment ajustés.Another disadvantage appears in the generation of annoying acoustic phenomena caused by room-to-room friction when the connection means are not sufficiently adjusted.

Un autre désavantage apparaît dans la transmission des vibrations du gros-oeuvre à l'ossature quand les dispositifs de liaison et de suspension forment une pièce unique rigide, les vibrations transmises provoquant l'apparition de fissures et/ou de fentes dans le plafond achevé.Another disadvantage appears in the transmission of vibrations from the shell to the frame when the connecting and suspension devices form a single rigid piece, the transmitted vibrations causing the appearance of cracks and / or cracks in the completed ceiling.

Enfin, un autre désavantage se manifeste lors de la mise en place du dispositif de liaison entre deux fourrures croisées dans deux plans distincts. Ce dispositif qui enserre trois des faces de la fourrure de la structure primaire sans en être solidaire, tend à être soulevé et chassé de sa position au moment où s'effectue l'encliquetage dans la fourrure de la structure secondaire quand le dispositif est du type étrier en forme de U (brevet EP 0 004 603), rendant laborieuse non seulement cette opération, mais aussi le réglage du pas entre fourrures.Finally, another disadvantage is manifested during the installation of the connection device between two furs crossed in two distinct planes. This device which encloses three of the faces of the fur of the primary structure without being integral with it, tends to be lifted and driven out of its position when the latching takes place in the fur of the secondary structure when the device is of the type U-shaped stirrup (patent EP 0 004 603), making laborious not only this operation, but also the adjustment of the pitch between furs.

Dès lors, un premier objet de l'invention vise à créer une ossature suspendue, à structures primaire et/ou secondaire, dont les profilés et/ou fourrures sont dotés d'un moyen de préréglage du pas de montage choisi parmi les multiples d'un pas multiplicande minimum, donnant aux profilés et/ou fourrures mis en oeuvre un caractère universel dans le choix du pas.Consequently, a first object of the invention aims to create a suspended framework, with primary and / or secondary structures, the profiles and / or furs of which are provided with a means for presetting the mounting pitch chosen from among the multiples of a minimum multiplicand pitch, giving the profiles and / or furs used a universal character in the choice of pitch.

Un autre objet de l'invention vise à créer, dans le domaine des ossatures suspendues à structures primaire et secondaire se croisant orthogonalement dans des plans différents, des dispositifs de liaison à montage rapide, adaptés au préréglage de pas et solidaires de la structure primaire avant que s'effectue la liaison avec la structure secondaire.Another object of the invention is to create, in the field of suspended frames with primary and secondary structures intersecting orthogonally in different planes, quick-assembly connecting devices, suitable for presetting steps and integral with the primary structure before that the link is made with the secondary structure.

Un autre objet de l'invention vise à créer, dans le domaine des ossatures suspendues à structures primaire et secondaire se croisant orthogonalement dans des plans différents, des dispositifs de suspension à montage rapide, indépendants du choix de pas souhaité, mais éventuellement adaptés au préréglage de pas.Another object of the invention is to create, in the field of suspended frames with primary and secondary structures intersecting orthogonally in different planes, quick mounting suspension devices, independent of the choice of pitch desired, but possibly adapted to the presetting. to not.

Un autre objet de l'invention vise à créer, dans le domaine des ossatures suspendues à structures primaire et secondaire se croisant orthogonalement dans des plans différents, des dispositifs de liaison et de suspension à montage rapide dotés d'un moyen de verrouillage automatique en position montée mais restant d'un démontage facile et rapide.Another object of the invention is to create, in the field of suspended frames with primary and secondary structures intersecting orthogonally in different planes, connection and suspension devices with quick mounting provided with an automatic locking means in position assembled but remaining easy and quick disassembly.

Un dernier objet de l'invention vise à créer, dans le domaine des ossatures suspendues à structures primaire et secondaire se croisant orthogonalement, des dispositifs de liaison et de suspension ne transmettant pas les phénomènes acoustiques et/ou les vibrations transmises par le gros-oeuvre.A final object of the invention aims to create, in the field of suspended frames with primary and secondary structures crossing orthogonally, connection and suspension devices which do not transmit the acoustic phenomena and / or the vibrations transmitted by the main structure .

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

La structure primaire de l'ossature selon l'invention est constituée de profilés ayant une section en U, en C ou en I, et dotée d'un moyen de préréglage du pas de montage de la structure secondaire permettant le positionnement automatique du dispositif de liaison entre les deux structures. Ce moyen détermine un pas multiplicande minimum qui se définit comme un sous-multiple commun aux entraxes des fourrures des structures secondaires.The primary structure of the frame according to the invention consists of profiles having a U, C or I section, and provided with means for presetting the pitch of mounting of the secondary structure allowing the automatic positioning of the device. link between the two structures. This means determines a minimum multiplicand pitch which is defined as a submultiple common to the centers of the furs of the secondary structures.

Ce moyen de préréglage consiste en une graduation régulière de l'une au moins des faces des profilés de la structure primaire par l'intermédiaire d'une empreinte en creux ou en relief.This presetting means consists of a regular graduation of at least one of the faces of the profiles of the primary structure by means of an em preprinted in relief or in relief.

Dans le cas où l'empreinte présente une forme non longiligne telle que préférentiellement une cuvette, un mamelon, une perforation, cette graduation est préférentiellement réalisée selon un axe parallèle à l'axe longitudinal de ladite face ou confondu avec celui-ci. Dans le cas où l'empreinte présente une forme de tendance longiligne telle que rainure ou saillie, la graduation est préférentiellement réalisée le long de l'un au moins des bords ou arêtes du profilé selon une direction perpendiculaire à l'axe longitudinal dudit profilé.In the case where the imprint has a non-elongated shape such as preferably a bowl, a nipple, a perforation, this graduation is preferably carried out along an axis parallel to or coincident with the longitudinal axis of said face. In the case where the imprint has a shape of longilinear tendency such as groove or projection, the graduation is preferably carried out along at least one of the edges or edges of the profile in a direction perpendicular to the longitudinal axis of said profile.

Dès lors, le pas multiplicande minimum se définit par la distance existant entre les entraxes de deux empreintes contiguës, cette distance étant préférentiellement choisie dans l'intervalle de 5 centimètres à 30 centimètres.Consequently, the minimum multiplicand pitch is defined by the distance existing between the centers of two contiguous imprints, this distance being preferably chosen in the interval from 5 centimeters to 30 centimeters.

Ainsi le préréglage du pas de montage est acquis en faisant le choix le plus approprié pour la réalisation d'un multiple du pas multiplicande minimum qui est reproduit sur l'ensemble de la structure primaire pour créer la structure secondaire et dès lors, l'ossature.Thus the preset of the mounting pitch is acquired by making the most appropriate choice for the realization of a multiple of the minimum multiplicand pitch which is reproduced on the whole of the primary structure to create the secondary structure and therefore, the framework .

Le dispositif de liaison entre les structures croisées primaire et secondaire de l'ossature selon l'invention est, d'une manière connue, un étrier en forme de U dont la partie centrale a une longueur équivalente à la largeur de la face du profilé sur lequel il prend appui. Les ailes de l'étrier sont repliées dans le même sens et sont dotées, à leurs extrémités, de moyens d'encliquetage de telle sorte que lesdites ailes, enserrant les flancs du profilé de la structure primaire, s'encliquètent dans la fourrure de la structure secondaire.The connecting device between the primary and secondary crossed structures of the frame according to the invention is, in a known manner, a U-shaped stirrup whose central part has a length equivalent to the width of the face of the profile on which it is supported. The wings of the stirrup are folded in the same direction and are provided, at their ends, with latching means such that said wings, enclosing the sides of the profile of the primary structure, snap into the fur of the secondary structure.

Ce dispositif de liaison selon l'invention comporte un moyen d'adaptation au pas multiplicande minimum des profilés de la structure primaire, ce moyen d'adaptation consistant en une empreinte du type mâle quand l'empreinte de la graduation du profilé de la structure primaire est du type femelle et réciproquement.This connecting device according to the invention comprises a means of adaptation to the minimum multiplicand pitch of the profiles of the primary structure, this adaptation means consisting of an imprint of the male type when the imprint of the graduation of the profile of the primary structure is of the female type and vice versa.

Le moyen d'adaptation est situé sur la partie centrale de l'étrier ou sur l'une au moins de ses ailes selon la position de l'empreinte de la graduation sur le profilé de la structure primaire et selon la forme non longiligne ou longiligne qui lui est donnée.The adaptation means is located on the central part of the stirrup or on at least one of its wings according to the position of the imprint of the graduation on the profile of the primary structure and according to the non-elongated or elongated shape. given to him.

Ainsi, quand l'empreinte de la graduation sur le profilé de la structure primaire est un creux tel que parexem- ple une cuvette, une rainure, le moyen d'adaptation du dispositif de liaison est en relief tel que par exemple un mamelon, une saillie. De cette manière, l'empreinte du moyen de préréglage de pas sur le profilé de la structure primaire et l'empreinte du moyen d'adaptation du dispositif de liaison sont en concordance de formes, exactement complémentaires.Thus, when the imprint of the graduation on the profile of the primary structure is a hollow such as for example a bowl, a groove, the means of adaptation of the connecting device is in relief such as for example a nipple, a protrusion. In this way, the imprint of the step presetting means on the profile of the primary structure and the imprint of the adaptation means of the connecting device are in concordance with shapes, exactly complementary.

Le dispositif de liaison selon l'invention peut comporter aussi un moyen d'anti-soulèvement du profilé qu'il enserre, lui facilitant l'encliquetage de l'extrémité de ses ailes dans la fourrure de la structure secondaire sans risque d'être soulevé et/ou déplacé lors de cette opération.The connection device according to the invention may also include a means of anti-lifting of the profile which it encloses, facilitating the snap-fastening of the end of its wings into the fur of the secondary structure without the risk of being raised. and / or moved during this operation.
