Description

La présente invention concerne le domaine des faux-plafonds, plus particulièrement les plafonds suspendus circulables, notamment ceux pouvant être installés dans des locaux spécialisés du type salles blanches ou locaux à atmosphère contrôlée.The present invention relates to the field of false ceilings, especially circulating suspended ceilings, particularly those that can be installed in specialized premises of the type clean rooms or local controlled atmosphere.

L'invention concerne plus précisément un dispositif de plafond suspendu circulable, ainsi qu'un procédé de réalisation d'un tel plafond suspendu.The invention relates more specifically to a circulable suspended ceiling device, as well as to a method of producing such a suspended ceiling.

Les plafonds ou faux-plafonds suspendus destinés à être mis en oeuvre dans le contexte évoqué ci-dessus doivent répondre à un certain nombre de critères et de contraintes.Suspended ceilings or suspended ceilings intended to be used in the context referred to above must meet a certain number of criteria and constraints.

Ainsi, ces plafonds suspendus doivent constituer une barrière sensiblement étanche entre le volume intérieur du local et le volume situé au-dessus dudit plafond suspendu (généralement désigné par plénum) et fournir une surface sensiblement plane et lisse au niveau de sa face tournée vers l'intérieur du local.Thus, these suspended ceilings must constitute a substantially watertight barrier between the interior volume of the room and the volume located above said suspended ceiling (generally referred to as plenum) and provide a substantially flat and smooth surface at its face facing towards the ceiling. inside the premises.

De plus, les interventions au niveau des plafonds suspendus du type précité s'effectuent par le dessus, en accédant de l'extérieur dans le volume formé par le plénum.In addition, the interventions at suspended ceilings of the aforementioned type are made from above, accessing from the outside in the volume formed by the plenum.

Ces interventions peuvent consister en des opérations de maintenance ou de remplacement tant au niveau des équipements, appareils, conduits ou accessoires techniques analogues montés dans le plafond suspendu, traversant ce dernier ou situés dans le plénum, que des éléments constitutifs du plafond suspendu lui-même.These interventions may consist of maintenance or replacement operations in terms of equipment, appliances, ducts or similar technical accessories mounted in the suspended ceiling, passing through the ceiling or located in the plenum, as components of the suspended ceiling itself. .

Ces interventions peuvent également consister en des travaux d'installation de nouveaux équipements, appareils ou analogues au niveau dudit plafond suspendu ou dans le plénum, avec éventuellement remplacement de certaines portions ou parties dudit plafond.These interventions may also consist of installation work of new equipment, devices or the like at the level of said suspended ceiling or in the plenum, possibly with replacement of certain portions or parts of said ceiling.

Un tel plafond suspendu doit par conséquent également permettre une circulation dans le plénum d'au moins un membre du personnel technique, éventuellement porteur d'une charge (outils, appareils, composant de remplacement), sans que cela entraîne une altération de sa cohésion, ni de ses performances.Such a suspended ceiling must therefore also allow a circulation in the plenum of at least one member of the technical staff, possibly carrying a load (tools, appliances, replacement component), without this entailing an alteration of its cohesion, nor of its performances.

De même, un tel plafond suspendu devrait également présenter une structure modulaire permettant un remplacement relativement aisé d'un ou d'un nombre limité de ses éléments ou composants constitutifs.Similarly, such a suspended ceiling should also have a modular structure allowing a relatively easy replacement of one or a limited number of its constituent elements or components.

Par le document EP 0 681 069 , on connaît déjà un dispositif de plafond suspendu circulable, notamment pour salles blanches, répondant sensiblement aux critères et contraintes indiqués ci-dessus.By the document EP 0 681 069 already known circulable suspended ceiling device, especially for clean rooms, substantially meeting the criteria and constraints indicated above.

Ce plafond suspendu circulable définit une face dirigée vers l'intérieur du local et une face opposée circulable. Il est essentiellement constitué, d'une part, par des panneaux de forme rectangulaire, juxtaposés avec aboutement et montés de manière suspendue à une dalle supérieure ou à une ossature de la charpente du bâtiment concerné et, d'autre part, par des moyens de suspension localisée sous la forme d'ensembles prémontés ou préassemblés formant suspentes, et venant en prise au niveau de bords longitudinaux renforcés desdits panneaux. Chaque suspente est composée de deux sous-ensembles structurels assemblés entre eux, à savoir un premier sous-ensemble de fixation à la dalle ou à l'ossature et un second sous-ensemble d'accrochage des panneaux, chaque suspente venant en prise avec deux panneaux adjacents dont elle assure une suspension localisée.This circulable suspended ceiling defines a face directed towards the interior of the room and an opposite face that can be moved. Essentially, it consists of rectangular panels juxtaposed with butts and mounted suspended from an upper slab or a skeleton of the structure of the building concerned and, secondly, by means of localized suspension in the form of pre-assembled or pre-assembled sets forming lines, and engaging at reinforced longitudinal edges of said panels. Each line is composed of two structural subassemblies assembled together, namely a first subassembly for fixing to the slab or the frame and a second subassembly for fastening the panels, each line coming into engagement with two adjacent panels which it ensures a localized suspension.

Cette structure de plafond suspendu connu fournit une surface intérieure plane, lisse et pratiquement continue à l'exception de faibles interstices entre panneaux, aisément colmatables.This known suspended ceiling structure provides a flat, smooth and practically continuous inner surface with the exception of small interstices between panels, which are easily clogged.

Toutefois, les moyens de suspension et d'accrochage mis en oeuvre dans cette construction connue présentent une constitution complexe et nécessitent obligatoirement la mise en place préalablement de rails de suspension fixés sur la dalle ou l'ossature métallique.However, the suspension and attachment means used in this known construction have a complex constitution and necessarily require the prior establishment of suspension rails attached to the slab or the metal frame.

De plus, les moyens de suspension doivent être assemblés avec les panneaux avant leur fixation et le montage s'effectue par conséquent d'un seul bloc.In addition, the suspension means must be assembled with the panels before their attachment and the assembly is therefore carried out in a single block.

Enfin, le remplacement d'un panneau isolé est fastidieux et la liaison entre panneaux adjacents est réalisée par l'intermédiaire de moyens de verrouillage également de constitution complexe.Finally, the replacement of an insulated panel is tedious and the connection between adjacent panels is carried out by means of locking means also of complex constitution.

La présente invention a justement pour but de pallier aux limitations de la solution connue évoquée ci-dessus et de proposer une solution améliorée, plus simple, plus économique et plus facile à mettre en oeuvre.The present invention aims precisely to overcome the limitations of the known solution mentioned above and to provide an improved solution, simpler, more economical and easier to implement.

A cet effet, elle a pour objet un dispositif de plafond suspendu circulable, notamment pour salles blanches, définissant une face dirigée vers l'intérieur du local et une face opposée circulable, essentiellement constitué, d'une part, par des panneaux de forme rectangulaire, juxtaposés avec aboutement et montés de manière suspendue à une dalle supérieure ou à une ossature de la charpente et, d'autre part, par des moyens de suspension localisée sous la forme d'ensembles prémontés ou préassemblés formant suspentes, et venant en prise par accrochage au moins au niveau de bords longitudinaux renforcés desdits panneaux, chaque suspente étant composée de deux sous-ensembles structurels assemblés entre eux, à savoir un premier sous-ensemble de fixation à la dalle ou à l'ossature et un second sous-ensemble d'accrochage des panneaux, chaque suspente venant en prise avec deux panneaux adjacents dont elle assure une suspension localisée, dispositif caractérisé en ce que le sous-ensemble d'accrochage est constitué par deux pièces profilées coopérantes ayant chacune une forme en section sensiblement en S, assemblées entre elles selon une disposition mutuellement en regard de telle manière que leurs portions d'extrémité supérieure en forme de crochets se chevauchent au moins partiellement au niveau de leurs zones d'accrochage respectives avec le premier sous-ensemble et que leurs portions d'extrémité inférieure en forme de crochets s'étendent latéralement de manière mutuellement divergente, les deux pièces profilées coopérantes étant en contact surfacique intime au moins à proximité de leurs portions d'extrémité inférieure respectives et en ce qu'au moins les bords longitudinaux des panneaux sont pourvus de ou formés par des portions de profilé à section en C destinés à venir en prise dans les crochets inférieurs et en butée contre les portions en contact intime des paires de pièces profilées constituant ensemble chaque sous-ensemble d'accrochage.For this purpose, it relates to a circulable suspended ceiling device, especially for clean rooms, defining a directed face towards the interior of the room and an opposite, circulable face, essentially constituted, on the one hand, by panels of rectangular shape, juxtaposed with abutment and mounted suspended from an upper slab or a skeleton of the frame and, on the other hand, by means of localized suspension means in the form of pre-assembled or pre-assembled assemblies forming suspensions, and engaging by at least at the level of reinforced longitudinal edges of said panels, each suspension being composed of two structural subassemblies assembled between they, namely a first subassembly for fixing to the slab or the frame and a second subassembly of attachment of the panels, each hanger engaging with two adjacent panels which it ensures a localized suspension, characterized that the attachment subassembly consists of two cooperating profiled parts each having a substantially S-shaped section, assembled together mutually opposite each other so that their hook-shaped upper end portions overlap at least partially at their respective hooking regions with the first subassembly and that their end portions hook-shaped lower members extend laterally mutually diverging, the two cooperating profiled pieces being in intimate surface contact at least near their respective lower end portions and in that at least the longitudinal edges of the panels are provided or formed by C-section profile portions for engaging the lower hooks and abutting the intimate contact portions of the pairs of profiled pieces together forming each attachment subassembly.

La figure 1, et partiellement les figures 3 et 7 à 10, montrent un dispositif 1 de plafond suspendu circulable, notamment pour salles blanches, définissant une face 1" dirigée vers l'intérieur du local et une face 1' opposée circulable.The figure 1 , and partially figures 3 and 7 to 10 , show a suspended ceiling device 1 circulable, especially for clean rooms, defining a face 1 "facing the interior of the room and an opposite side 1 'circulable.

Ce plafond suspendu 1 est essentiellement constitué, d'une part, par des panneaux 2 de forme rectangulaire, juxtaposés avec aboutement et montés de manière suspendue à une dalle supérieure 3 ou à une ossature 3' de la charpente et, d'autre part, par des moyens 4 de suspension localisée sous la forme d'ensembles prémontés ou préassemblés formant suspentes, et venant en prise par accrochage au moins au niveau de bords longitudinaux renforcés 2' desdits panneaux 2. Chaque suspente 4 étant composée de deux sous-ensembles structurels assemblés entre eux, à savoir un premier sous-ensemble 5 de fixation à la dalle 3 ou à l'ossature 3' et un second sous-ensemble 6 d'accrochage des panneaux 2, chaque suspente 4 venant en prise avec deux panneaux 2 adjacents dont elle assure une suspension localisée.This suspended ceiling 1 essentially consists, on the one hand, of panels 2 of rectangular shape, juxtaposed with abutment and mounted suspended from an upper slab 3 or a framework 3 'of the frame and, on the other hand, by localized suspension means 4 in the form of pre-assembled or pre-assembled assemblies forming a suspension, and engagingly engaging at least at longitudinal edges reinforced 2 'of said panels 2. Each hanger 4 is composed of two structural subassemblies assembled together, namely a first subassembly 5 fixing to the slab 3 or the 3' frame and a second subset 6 hanging panels 2, each hanger 4 engaging two adjacent panels 2 which it ensures a localized suspension.

Conformément à l'invention, le sous-ensemble d'accrochage 6 est constitué par deux pièces profilées coopérantes 7 et 7' ayant chacune une forme en section sensiblement en S, assemblées entre elles selon une disposition mutuellement en regard de telle manière que leurs portions d'extrémité supérieure 8, 8' en forme de crochets se chevauchent au moins partiellement au niveau de leurs zones d'accrochage respectives avec le premier sous-ensemble 5 et que leurs portions d'extrémité inférieure 9, 9' en forme de crochets s'étendent latéralement de manière mutuellement divergente, les deux pièces profilées 7 et 7' coopérantes étant en contact surfacique intime au moins à proximité de leurs portions d'extrémité inférieure respectives 9 et 9' et en ce qu'au moins les bords longitudinaux 2' des panneaux 2 sont pourvus de ou formés par des portions de profilé à section en C 10 destinés à venir en prise dans les crochets inférieurs 9 et 9' et en butée contre les portions 11 et 11' en contact intime des paires de pièces profilées 7 et 7' constituant ensemble chaque sous-ensemble d'accrochage 6.According to the invention, the attachment subassembly 6 is constituted by two cooperating profiled pieces 7 and 7 'each having a substantially S-shaped section, assembled together in mutually opposite arrangement so that their portions hook-shaped upper end 8, 8 'overlap at least partially at their respective hooking regions with the first subassembly 5 and that their hook-shaped lower end portions 9, 9' extend laterally mutually diverging, the two cooperating profiled parts 7 and 7 'being in intimate surface contact at least near their respective lower end portions 9 and 9' and in that at least the longitudinal edges 2 ' panels 2 are provided with or formed by C-section profile portions intended to engage in the lower hooks 9 and 9 'and abut against the pores. 11 and 11 'in intimate contact pairs of profiled parts 7 and 7' together constituting each attachment subassembly 6.

Ainsi, chaque suspente 4 présente une structure simple, et démontable, même après installation du plafond suspendu 1, et leur liaison avec les panneaux 2 par simple accrochage des profilés en C 10 dans les crochets inférieurs 9, 9' autorise aussi un démontage simple et unitaire des panneaux 2, par exemple pour les interchanger.Thus, each hanger 4 has a simple structure, and removable, even after installation of the suspended ceiling 1, and their connection with the panels 2 by simply hooking the C 10 profiles in the lower hooks 9, 9 'also allows simple disassembly and unitary panels 2, for example to interchange.

Le sous-ensemble d'accrochage 6 formé par coopération des deux pièces profilées en S 7 et 7' présente ainsi trois parties de formes différentes, à savoir, en partant du haut, une boucle solidarisée avec le sous-ensemble de fixation 5, une partie intermédiaire très mince permettant le passage entre les panneaux 2 adjacents en créant un interstice 20 de faible largeur et une partie inférieure s'étendant latéralement sous la forme de deux crochets 9, 9' opposés.The fastening subassembly 6 formed by cooperation of the two profiled pieces S 7 and 7 'thus has three parts of different shapes, namely, from the top, a loop secured to the fastening subassembly 5, a very thin intermediate part allowing the passage between adjacent panels 2 by creating a gap 20 of small width and a lower portion extending laterally in the form of two hooks 9, 9 'opposite.

Afin de créer simplement un plénum de hauteur suffisante et de permettre aux suspentes 4 de supporter des charges maximales pour un dimensionnement donné du sous-ensemble d'accrochage 6, le premier sous-ensemble de fixation 5 présente une structure allongée définissant un axe longitudinal X coplanaire avec la surface de contact 11" entre les deux pièces profilées 7 et 7' et les portions de profilé à section en C 10 viennent en appui par leurs ailes supérieures repliées 10' dans les crochets inférieurs 9 et 9' au plus près latéralement de ladite surface de contact 11 ", limitant ainsi le porte-à-faux au niveau desdits crochets 9 et 9', par exemple sous la forme de L avec une aile libre repliée, tout en réalisant un calage entre panneaux 2 adjacents dans la direction perpendiculaire à la surface 11 ".In order to simply create a plenum of sufficient height and to allow the lines 4 to withstand maximum loads for a given dimensioning of the attachment subassembly 6, the first fixing subassembly 5 has an elongated structure defining an axis longitudinal X co-planar with the contact surface 11 "between the two profiled parts 7 and 7 'and the C-section profile portions 10 are supported by their upper folded wings 10' in the lower hooks 9 and 9 'as close as possible laterally of said contact surface 11 ", thus limiting the cantilever at said hooks 9 and 9 ', for example in the form of L with a folded free wing, while making a wedging between panels 2 adjacent in the direction perpendicular to the surface 11 ".

En vue de permettre un blocage avec verrouillage du montage des panneaux 2 sur les suspentes 4 et simultanément de renforcer la cohésion structurelle du plafond suspendu 1, il est avantageusement prévu que le crochet inférieur 9 de l'une 7 des deux pièces profilées en S est prolongé par une aile 12 formant une portion d'appui contre et de solidarisation avec l'âme de la portion de profilé en C 10 du panneau 2 avec lequel il est en engagement.In order to allow blocking with locking of the mounting of the panels 2 on the lines 4 and at the same time to reinforce the structural cohesion of the suspended ceiling 1, it is advantageously provided that the bottom hook 9 of one of the two S-shaped pieces is extended by a flange 12 forming a bearing portion against and securing with the core of the profile portion C 10 of the panel 2 with which it is engaged.

La solidarisation de l'aile 12 d'une suspente 4 avec la portion 10 de profilé en C longitudinale correspondante d'un panneau 2 correspondant peut par exemple s'effectuer au moyen d'une vis 12'.The fastening of the wing 12 of a hanger 4 with the portion 10 of corresponding longitudinal C-section of a corresponding panel 2 may for example be effected by means of a screw 12 '.

En accord avec un mode de réalisation particulièrement simple, économique et pratique de l'invention, ressortant notamment des figures 3, 6, 11 et 12 des dessins annexés, le premier sous-ensemble 5 est constitué par une tige 13 pourvue d'un décrochement ou épaulement radial extérieur 14 et les portions d'extrémité supérieure en forme de crochets 8 et 8' des deux pièces profilées en S 7 et 7' présentent chacune une configuration en fourche avec une découpe médiane 15 en forme de fente dans laquelle la tige 13 peut s'engager latéralement, préférentiellement de manière sensiblement ajustée.In accordance with a particularly simple, economical and practical embodiment of the invention, particularly figures 3 , 6 , 11 and 12 In the accompanying drawings, the first subassembly 5 is constituted by a rod 13 provided with a recess or external radial shoulder 14 and the hook-shaped upper end portions 8 and 8 'of the two S-shaped profiled pieces 7 and 7. each have a fork configuration with a slot-shaped median cut-out in which the rod 13 can engage laterally, preferably in a substantially adjusted manner.

On obtient ainsi une construction des suspentes 4 facile à assembler et aisément démontable.This produces a construction of the lines 4 easy to assemble and easily removable.

Selon une autre caractéristique de l'invention, autorisant un réglage aisé de la hauteur de suspension, la tige 13 est une tige au moins partiellement filetée, notamment au niveau d'une zone proche de son extrémité inférieure, et le décrochement ou épaulement radial 14 est formé par au moins une rondelle ou pièce analogue 14' associée à au moins un, préférentiellement deux, écrou(s) 14" monté(s) au niveau de ladite zone proche de son extrémité inférieure.According to another characteristic of the invention, allowing easy adjustment of the suspension height, the rod 13 is an at least partially threaded rod, particularly at a zone near its lower end, and the recess or radial shoulder 14 is formed by at least one washer or similar part 14 'associated with at least one, preferably two, nut (s) 14 "mounted (s) at said zone near its lower end.

Pour aboutir à une construction rigide et simultanément simple et économique à réaliser, faisant état d'une grande résistance à la traction, il peut être prévu, selon l'invention, que les portions d'extrémité supérieure 8, 8' en forme de crochets présentent des sections en forme de L avec un bord libre replié 8" et se chevauchent en se recouvrant mutuellement avec emboîtement ajusté, lesdites portions d'extrémité supérieure 8 et 8' mutuellement chevauchantes étant serrées l'une contre l'autre. En outre, les pièces profilées à section en S 7 et 7', ainsi que les portions de profilé en C 10, sont avantageusement réalisées en tôle d'acier pliée, préférentiellement galvanisé.To achieve a rigid construction and simultaneously simple and economical to achieve, indicating a high tensile strength, it According to the invention, it is possible for the hook-shaped upper end portions 8, 8 'to have L-shaped sections with a folded free edge 8 "and to overlap one another in mutually overlapping manner with said interlocking fit. the mutually overlapping upper end portions 8 and 8 'being tight to each other, furthermore, the S-section shaped sections 7 and 7', as well as the C-section portions 10, are advantageously made of folded steel sheet, preferentially galvanized.

Comme cela ressort des figures 3, 6C et 6D, les deux portions d'extrémité supérieure en forme de crochets 8 et 8' qui se chevauchent sont serrées entre, d'une part, la rondelle 14' bloquée en position et formant décrochement ou épaulement d'accrochage 14 et, d'autre part, un second ensemble rondelle 16/écrou 16' opposé.As is apparent from figures 3 , 6C and 6D , the two upper end portions in the form of hooks 8 and 8 'which overlap are clamped between, on the one hand, the washer 14' locked in position and forming recess or hooking shoulder 14 and on the other hand , a second washer assembly 16 / nut 16 'opposite.

En vue de conférer de manière simple une bonne cohésion structurelle au plafond suspendu 1, ce dernier peut comprendre en outre des plaquettes de liaison 17 reliant entre eux au moins deux, le cas échéant quatre, panneaux 2 au niveau de leurs coins adjacents, ce sur la face circulable supérieure 1' du plafond suspendu 1 (figures 1, 2 et 7E).In order to easily confer a good structural cohesion to the suspended ceiling 1, the latter may further comprise connecting plates 17 interconnecting at least two, where appropriate four, panels 2 at their adjacent corners, this on the upper moveable face 1 'of the suspended ceiling 1 ( figures 1 , 2 and 7E ).

Comme le montrent en particulier les figures 2 et 7E, la solidarisation de ces plaquettes 17 avec les panneaux 2 s'effectue avantageusement au moyen d'éléments de fixation du type vis, venant en prise avec les cadres des panneaux 2 formés par les profilés 10 et 10". Les plaquettes 2 peuvent comporter un jour ou un orifice central autorisant un contrôle de positionnement desdites plaquettes 17 par rapport au panneau 2, ainsi que de l'assemblage en coin de ces derniers.As shown in particular by figures 2 and 7E the fastening of these plates 17 with the panels 2 is advantageously effected by means of fastening elements of the screw type, engaging with the frames of the panels 2 formed by the sections 10 and 10 ". The plates 2 may comprise a day or a central orifice allowing a positioning control of said plates 17 relative to the panel 2, and the corner assembly of the latter.

Conformément à une autre caractéristique de l'invention, ressortant notamment des figures 4, 5 et 7 des dessins annexés, les panneaux 2 présentent une constitution composite avec deux parements extérieurs opposés 18 et 18' destinés à former les deux faces opposées 1' et 1" du plafond, un matériau de remplissage intérieur en plaque 19 à propriété d'isolation thermique et/ou phonique, préférentiellement autoportant et faisant état de propriétés anti-feu, et des portions 10 et 10" de profilé en C, ouverts sur l'extérieur, formant un cadre périphérique. Les différentes composantes 18, 18', 19, 10 et 10" constitutives sont avantageusement assemblées entre elles par collage structural aboutissant à une constitution monobloc et la longueur des panneaux 2 est préférentiellement sensiblement un multiple entier de leur largeur, par exemple le double de cette dernière.According to another characteristic of the invention, Figures 4, 5 and 7 In the accompanying drawings, the panels 2 have a composite constitution with two opposing outer facings 18 and 18 'intended to form the two opposite faces 1' and 1 "of the ceiling, a plate internal filler material 19 with thermal insulation property and / or phonic, preferably self-supporting and showing fireproof properties, and portions 10 and 10 "of C-profile, open on the outside, forming a peripheral frame. The various components 18, 18 ', 19, 10 and 10 "constituting are advantageously assembled together by structural bonding resulting in a one-piece constitution and the length of the panels 2 is preferentially substantially an integer multiple of their width, for example twice that of the latter.

De manière pratique, les parements 18 et 18' peuvent par exemple consister en des tôles d'acier, préférentiellement prétraitées en surface, notamment prélaquées, repliées au niveau de leurs bords en partie sur les ailes libres des portions de profilé en C 10 et fournissant des surfaces planes pour les deux faces opposées des panneaux 2, au moins les interstices 20 situés côté face 1" tournée vers l'intérieur du local étant obturés par un joint 21 rapporté affleurant.Conveniently, the facings 18 and 18 'may for example consist of steel sheets, preferably pretreated at the surface, in particular prelacked, folded at their edges partly on the free wings of the C 10 profile portions and providing flat surfaces for the two opposite faces of the panels 2, at least the interstices 20 located on the face side 1 "facing the interior of the room being closed by a seal 21 flush mounted.

Comme le montre la figure 1 des dessins annexés, le dimensionnement des panneaux 2 et des suspentes 4 est tel qu'il y a lieu de prévoir deux suspentes 4 sur chaque côté longitudinal 2' d'un panneau 2, pour la réalisation d'un plafond suspendu circulable 1.As shown in figure 1 appended drawings, the dimensioning of the panels 2 and the lines 4 is such that it is necessary to provide two lines 4 on each longitudinal side 2 'of a panel 2, for the realization of a suspended ceiling circulable 1.

A titre d'exemple de réalisation pratique, les panneaux 2 à structure composite monobloc peuvent par exemple présenter une longueur de 2400 mm et une largeur de 1200 mm, ainsi qu'une épaisseur de l'ordre de 52 mm. Ces panneaux peuvent être constitués par l'assemblage par collage structural (colle polyuréthanne ou autre) de deux parements 18 et 18' en tôle d'acier (par exemple d'épaisseur 60/100ème, 75/100ème, 100/100ème ou plus) recouvert d'une laque polyester (PET, PVDF, Epoxy-polyester ou analogue), d'un corps central 19 en laine de roche M0 (par exemple de type connu sous la désignation FORTA 130 / densité 130 kg/m3, épaisseur 50 mm) et d'un cadre soudé en portions de profilé d'acier en C 10 et 10" (hauteur 50 mm / épaisseur 2 mm).As an example of practical embodiment, the panels 2 with a single-piece composite structure may for example have a length of 2400 mm and a width of 1200 mm, and a thickness of about 52 mm. These panels can be constituted by the assembly by structural bonding (polyurethane glue or other) of two facings 18 and 18 'made of sheet steel (for example of thickness 60/100 th , 75/100 th , 100/100 th or more) coated with a polyester lacquer (PET, PVDF, Epoxy-polyester or the like), a central body 19 made of rockwool M0 (for example of the type known under the designation FORTA 130 / density 130 kg / m 3 thickness 50 mm) and a welded frame in C 10 and 10 "steel profile sections (height 50 mm / thickness 2 mm).

La fixation de la tige 13 sur les poutres profilées en I d'une ossature métallique 3' peut par exemple être réalisée au moyen d'une ensemble de fixation du type connu sous la désignation "Halfen", fournissant une structure porteuse intermédiaire sous la forme d'un rail ou d'une goulotte profilé(e) solidarisé(e) aux poutres de l'ossature 3', par exemple par l'intermédiaire d'une plaque taraudée 3"' (voir figure 8).The fixation of the rod 13 on the I-beams I of a metal frame 3 'can for example be achieved by means of a fixing assembly of the type known under the designation "Halfen", providing an intermediate support structure in the form a profiled rail or chute (e) secured to the beams of the frame 3 ', for example by means of a threaded plate 3 "' (see figure 8 ).

La fixation de la tige 13 dans une dalle de béton 3 au niveau de sites d'ancrage 22 repérés préalablement peut par exemple s'effectuer au moyen de chevilles adaptées (par exemple du type HSC-1), comme le montre la figure 9 des dessins annexés.Fixing the rod 13 in a concrete slab 3 at previously identified anchoring sites 22 may for example be effected by means of suitable dowels (for example of the HSC-1 type), as shown in FIG. figure 9 attached drawings.

La présente invention a également pour objet un procédé de réalisation d'un plafond suspendu circulable 1 tel que décrit précédemment et représenté aux dessins annexés.The present invention also relates to a method of producing a movable suspended ceiling 1 as described above and shown in the accompanying drawings.

Ce procédé consiste essentiellement à repérer, selon un motif d'implantation prédéfini, les sites 22 d'ancrage des sous-ensembles 5 de fixation des suspentes 4 et la hauteur souhaitée de la face 1" inférieure du plafond suspendu 1 tournée vers l'intérieur du local, fixer (figures 8 et 9) les suspentes 4 prémontées ou préassemblées dans la dalle supérieure 3 ou sur l'ossature métallique 3', le cas échéant après mise en place d'une structure porteuse intermédiaire 3", régler le positionnement en hauteur ou la longueur des différentes suspentes 4 en se référant au repérage préalable de la hauteur de la face inférieure 1" du plafond suspendu 1, mettre en place les panneaux 2 en les accrochant aux suspentes 4 (figures 7A à 7D), solidariser les panneaux 2 adjacents entre eux du côté de la face circulable 1' au moyen de plaquettes de liaison 17 (figure 7E) et colmater au moins les interstices 20 entre panneaux 2 côté face intérieure 1" par l'intermédiaire d'un joint 21 rapporté de manière affleurante (figure 7F).This method consists essentially of identifying, according to a predefined implantation pattern, the anchoring sites 22 of the subassemblies 5 for fixing the lines 4 and the desired height of the lower face 1 "of the suspended ceiling 1 facing inwards. of the local, fix ( figures 8 and 9 ) the lines 4 pre-assembled or preassembled in the upper slab 3 or on the metal frame 3 ', if necessary after placing an intermediate support structure 3 ", adjust the height positioning or the length of the various lines 4 in Referring to the preliminary identification of the height of the lower face 1 "of the suspended ceiling 1, put up the panels 2 by hanging them on the lines 4 ( Figures 7A to 7D ), fasten the panels 2 adjacent to each other on the side of the movable face 1 'by means of connecting plates 17 ( figure 7E ) and sealing at least the interstices 20 between panels 2 on the inner side 1 "via a seal 21 reportedly flush ( figure 7F ).

Le repérage des sites 22 et le réglage de la hauteur de suspension pour les différentes suspentes 4 est avantageusement réalisé au moyen d'un niveau à laser.The location of the sites 22 and the adjustment of the suspension height for the various lines 4 is advantageously achieved by means of a laser level.

Comme l'illustrent les figures 6 des dessins annexés, le préassemblage ou prémontage des suspentes 4 consiste à fournir, d'une part, une tige filetée 13 pourvue de deux ensembles 14', 14" et 16, 16' rondelle/écrou formant le sous-ensemble de fixation 5 (figure 6A) et, d'autre part, deux pièces profilées complémentaires 7 et 7' à section en S destinées à former par coopération le sous-ensemble d'accrochage 6 (figures 11 et 12), à accrocher une première 7 desdites pièces profilées à section en S par sa portion d'extrémité supérieure 8 sur la rondelle 14' formant épaulement ou décrochement 14 et site d'accrochage (figure 6B), à accrocher de manière similaire la seconde pièce profilée 7' par sa portion d'extrémité supérieure 8' avec chevauchement emboîté sur la première 7 (figure 6C), les deux pièces 7 et 7' étant disposées mutuellement en regard avec leurs portions d'extrémité inférieure 9 et 9' formant deux crochets opposés, et à serrer les portions d'extrémité supérieure 8 et 8' mutuellement chevauchantes entre les deux ensembles 14', 14" et 16, 16' écrou(s)/rondelle pour verrouiller et rigidifier l'assemblage des deux sous-ensembles 5 et 6 (figure 6D).As illustrated by figures 6 In the accompanying drawings, the preassembly or pre-assembly of the lines 4 consists in providing, on the one hand, a threaded rod 13 provided with two sets 14 ', 14 "and 16, 16' washer / nut forming the fastening sub-assembly 5 ( Figure 6A ) and, on the other hand, two complementary profiled pieces 7 and 7 'with an S-section intended to form, by cooperation, the attachment subassembly 6 ( Figures 11 and 12 ), to hook a first 7 of said profiled S section pieces by its upper end portion 8 on the washer 14 'forming shoulder or recess 14 and hooking site ( Figure 6B ), to similarly hook the second profiled piece 7 'by its upper end portion 8' with overlapping nested on the first 7 ( Figure 6C ), the two parts 7 and 7 'being arranged mutually opposite their lower end portions 9 and 9' forming two opposite hooks, and to clamp the upper end portions 8 and 8 'mutually overlapping between the two sets 14 ', 14 "and 16, 16' nut (s) / washer to lock and stiffen the assembly of the two subassemblies 5 and 6 ( Figure 6D ).

On peut noter que l'assemblage des suspentes 4 peut être opéré selon deux variantes de réalisation, à savoir, soit en réalisant un assemblage des deux sous-ensembles 5 et 6 de chaque suspente avant la fixation des suspentes 4 au niveau de la dalle ou de l'ossature, soit en procédant à la fixation des sous-ensembles 5 (tige 13) au niveau de la dalle ou de l'ossature avant l'assemblage des pièces 7 et 7' formant le sous-ensemble 6 avec le sous-ensemble 5.It may be noted that the assembly of the lines 4 can be operated according to two embodiments, namely, by making an assembly of the two subassemblies 5 and 6 of each line before the fixing of the lines. suspension 4 at the slab or the frame, either by fixing the subsets 5 (rod 13) at the slab or the frame before the assembly of the parts 7 and 7 'forming the subassembly 6 with the subassembly 5.

Conformément à une caractéristique non représentée aux dessins annexés, au moins un des panneaux 2 peut être pourvu d'une découpe pour le montage d'un appareil, équipement ou accessoire (luminaire, filtre, terminal de climatisation, bouche d'entrée et de sortie, ...), préalablement ou postérieurement à l'installation dudit panneau 2 dans le plafond suspendu 1 en cours de montage.According to a feature not shown in the accompanying drawings, at least one of the panels 2 may be provided with a cutout for mounting an appliance, equipment or accessory (luminaire, filter, air conditioning terminal, inlet and outlet mouth , ...), before or after the installation of said panel 2 in the suspended ceiling 1 during assembly.

Enfin, comme le montre la figure 10 des dessins annexés, le procédé consiste également, avant mise en place des panneaux 2, à monter au niveau des murs et/ou cloisons 23 délimitant le local des profilés 24 à section en forme de L ou de cornière formant profilés de rive et fermant périphériquement le plafond suspendu 1 par obturation de l'interstice entre les murs ou cloisons 23 et les panneaux 2 périphériques, ces derniers reposant (préférentiellement sans charge) sur les ailes saillantes 24' desdits profilés 24 avec interposition d'un joint d'étanchéité 24".Finally, as shown in figure 10 appended drawings, the method also consists, before introduction of the panels 2 to be mounted at the walls and / or partitions 23 defining the local profiles 24 section L-shaped or angle forming edge profiles and closing peripherally the suspended ceiling 1 by closing the gap between the walls or partitions 23 and the peripheral panels 2, the latter resting (preferably without load) on the projecting flanges 24 'of said profiles 24 with the interposition of a seal 24 " .

Grâce à l'invention, il est par conséquent possible de fournir un plafond suspendu circulable à structure modulaire, permettant de surmonter les limitations et les inconvénients des réalisations antérieures.Thanks to the invention, it is therefore possible to provide a movable suspended ceiling modular structure, to overcome the limitations and disadvantages of previous achievements.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings.
