Description
L'invention se rapporte aux plafonds suspendus constitués -par des traverses profildes horizontales suspenducs à une dalle de plafond et supportant, par- des ailes latérales, des panneaux de remplissage dés espaces qui - les séparent.
Les plafonds suspendus de ce gindre sont bien connus et largement utilisés. Toutefois, leur mise'en oeuv're se heurte à des difficultés lorsqu'il s'agit de leur associer des cloisons'amovibles. la liaison entre une cloison amovible et-un plafond suspendu est malaisée.The invention relates to suspended ceilings consisting of horizontal profiled cross members suspended from a ceiling tile and supporting, by side wings, panels filling spaces - which separate them.
The suspended ceilings of this ginder are well known and widely used. However, their implementation encounters difficulties when it comes to associating them with removable partitions. the connection between a removable partition and a suspended ceiling is difficult.
De plus, si l'on supprime la cloison, par exemple pour la déplacer, des dégradations 'infigées au plafond suspendu pour le montage de la cloison apparaissent à l'ancien emplacement de celle-ci.In addition, if we remove the partition, for example to move it, degradations' infiltrated to the suspended ceiling for mounting the partition appear in the old location thereof.
L'invention a notamment pour but de remédier àces inconvénients. The object of the invention is in particular to remedy these drawbacks.
Elle a a cet effet pour objet un plafond suspendu ailes précitees. une du genre précité, dans lequel les traverses oht, entre les# structure creuse en forme de gouttière renversée et sont aménagées pour recevoir par emboftement la-partie supérieure de cloisons amovibles situés d leur aplomb. It has for this purpose a suspended ceiling above wings. one of the aforementioned kind, in which the cross-members oht, between the # hollow structure in the shape of an inverted gutter and are arranged to receive by fitting the upper part of removable partitions situated at their base.
I1 suffit dès lors de disposer chaque cloison amovible sous une traverse pour que l'emboîtement prévu soit possible, assurant une liaison simple-et efficace entrela cloison et le plafond suspendu. I1 is therefore sufficient to have each removable partition under a cross so that the planned nesting is possible, ensuring a simple and effective connection between the partition and the suspended ceiling.
Dans une forme d'exécution préférée, les traverses offrent des flancs verticaux et des rebords horizontaux s'étendant longitudinalement et formant ensemble un logement de réception de la partie supérieure desdites cloisons, qui se trouvent pour ainsi dire encastrées dans les traverses. Ce logement est de préférence adapté pour recevoir un profilé en U formant la partie supérieure desdites cloisons, ce profilé étant solidarisé de manière amovible à la traverse, par exemple par boulonnage. In a preferred embodiment, the crosspieces offer vertical sides and horizontal flanges extending longitudinally and together forming a housing for receiving the upper part of said partitions, which are, so to speak, embedded in the crosspieces. This housing is preferably adapted to receive a U-shaped profile forming the upper part of said partitions, this profile being removably secured to the cross member, for example by bolting.
Selon une autre caractéristique de l'invention, le logement précité est obturable, en l'absence de cloison, par un couvre-joint amovible. Ainsi, le volume creux d'une traverse quiapparaSt après démontage de la cloison qui s'y emboîtait se trouve masqué par pose d'un couvre-joint de sorte que le plafond suspendu présente par la suite un aspect impeccable a l'emplacement correspondant. According to another characteristic of the invention, the aforementioned housing can be closed, in the absence of a partition, by a removable joint cover. Thus, the hollow volume of a quiapparaSt cross member after dismantling the partition which fitted therein is hidden by fitting a joint cover so that the suspended ceiling subsequently has an impeccable appearance at the corresponding location.
D'autre part, il est avantageux quelles traverses soient on outre aménagées pour supporter des barrières phoniques et/ou thermiques amovibles, disposées entre le plafond suspendu et la dalle. On the other hand, it is advantageous which crosspieces are also arranged to support removable sound and / or thermal barriers, arranged between the suspended ceiling and the slab.
Dans les agencements de plafonds suspendus connus jusqu'ici, il n'y a que deux façons de "marier" valablement plafond suspendu et cloisons amovibles tout en garantissant à l'utilisateur une bonnsolation thermique ou pbonique :
a) utiliser un plafond suspendu de type "lourd" sur toute la surface, @@ nécessitant pas de barrières phoniques ou thermiques, nais étant d'un prix élevé;
b) installer des barrières phoniques ou thermiques à l'avace au droit de chacun des axes prévus pour recevoir ultérieurement des cloisons, ce qui conduit également à un prix élevé.In the arrangements of suspended ceilings known up to now, there are only two ways to "marry" validly suspended ceiling and removable partitions while guaranteeing to the user a good thermal or pbonic insulation:
a) use a “heavy” type suspended ceiling over the entire surface, @@ requiring no sound or thermal barriers, but being of a high price;
b) install sound or thermal barriers on the avar to the right of each of the axes provided for later receiving partitions, which also leads to a high price.
Par contre, dans le cas du plafond suspendu selon l'invention, les barrières peuvent se déplacer avec. les cloisons, cumulant ainsi les avantages d'un plafond suspendu de type "léger" et d!un nombre de barrières phoniques ou thermiques réduit au strict minimum, et cela avec d'excellents résultats. On the other hand, in the case of the suspended ceiling according to the invention, the barriers can move with. partitions, thus combining the advantages of a "light" type suspended ceiling and a number of sound or thermal barriers reduced to the strict minimum, and this with excellent results.
De préférence, ces. barrières amovibles sont soutenues par la partie dorsale des traverses, opposée au logement précité. Elles pouvent #tre constituées par deux plaques verticales reposant dans des étriers montés sur les traverses et tenues par des organes de serrage fixés à la dalle. De plus, ces plaques sont de préférence séparées par un intervalle, lequel est rempli de matière acoustiquement et/ou thermiquement isolante. Preferably, these. removable barriers are supported by the dorsal part of the crosspieces, opposite the aforementioned housing. They can be constituted by two vertical plates resting in stirrups mounted on the crosspieces and held by clamping members fixed to the slab. In addition, these plates are preferably separated by a gap, which is filled with acoustically and / or thermally insulating material.
Il sera généralement utile d'aménager les traverses d!un plafond suspendu selon l'invention pour qu'elles puissent recevoir à leur intérieur des accessoires divers tels que supports de câbles ou dispositif@ d'éclairage. It will generally be useful to arrange the crosspieces of a suspended ceiling according to the invention so that they can receive inside them various accessories such as cable supports or lighting device.
Des câbles circulant ainsi dans des traverses seront cachés par ds couvres-joints.Cables thus circulating in sleepers will be hidden by joint covers.
Les traverse; peuvent ttre percées, en cas de besoin, de trous d'aération ou de reprise d'air, permettant d'assurer une ventilation du local équipé du plafond auspendu en @@ ttant à profit l'intervalle séparant ledit plafond et la dalle. Crosses them; can be pierced, if necessary, ventilation holes or air intake, to ensure ventilation of the room equipped with the suspended ceiling @ @ taking advantage of the interval between said ceiling and the slab.
En résumé, dans un plafond suspendu selon l'invention, les traverses porteuses des panneaux de remplissage sont conçues pour recevoir les cloisons amovible que l'in désire installer sous le plafond suspendu et qui s'y trouvent fixées. Des barrières d'isolement peuvent au @u@plus être montées entre traverses et dalle de plafond,
Ces cloisons et barrières sont aisément déplaçables, autant de fois qu'on le désire, sans que leur enlèvement laisse apparaître des dégradations (par exemple des trous de perçage dans le plafond suspendu). Les traverses sans cloison peuvent être obturées par des couvre-joints.In summary, in a suspended ceiling according to the invention, the carrying crosspieces of the filling panels are designed to receive the removable partitions which it wishes to install under the suspended ceiling and which are fixed there. Isolation barriers can also be installed between sleepers and ceiling tiles,
These partitions and barriers are easily movable, as many times as desired, without their removal revealing damage (for example drilling holes in the suspended ceiling). Sleepers without partitions can be closed off with joint covers.
Elles sont d'autre part utilisables en tant que réceptacles de câbles, d'appareils d'éclairage, etc. Percées de trous, elles pormettent d'établir des passages de ventilation d'un côté à l'autre du plafond suspendu, sans qu'il soit besoin de prévoir des ouvertures dans les panneaux de remplissage.They can also be used as receptacles for cables, lighting fixtures, etc. Drilled with holes, they allow ventilation passages to be established from one side to the other of the suspended ceiling, without the need to provide openings in the filler panels.
La description qui va suivre, en regard du dessin annexé à titre d'exemple non limitatif, permettra de bien comprendre comment la présente invention peut être mise en pratiqua. The description which follows, with reference to the attached drawing by way of nonlimiting example, will make it possible to understand clearly how the present invention can be put into practice.
La figure 1 représente, on coupe par un plan vertical perpendiculaire à la direction des traverses porteuses, un exemple de réalisation d'un plafond suspendu selon l'invention. Figure 1 shows, one cuts by a vertical plane perpendicular to the direction of the carrying crosspieces, an embodiment of a suspended ceiling according to the invention.
Les figures 2 et 3 représentent en perspective respectivement les organes de maintien d'une barrière thermique ou phonique amovible associée à un plafond suspendu selon l'invention. Figures 2 and 3 respectively show in perspective the holding members of a removable thermal or sound barrier associated with a suspended ceiling according to the invention.
Le plafond suspendu 1 représenté comprend essentiel- lement une ossature métallique 2 porteuse de panneaux de remplissage 3, lesquels peuvent églaement être métalliques (bacs d'acier). L'ossature 2 se compose de traverses profilées 4 comportant des ailes d'appui 5 pour les panneaux 3; cea traverses, qui ont la forme générale de gouttières renversées, sont suspendues par des tiges filetées 6 à la dalle de plafond 7. The suspended ceiling 1 shown essentially comprises a metal frame 2 carrying filling panels 3, which may also be metallic (steel trays). The frame 2 consists of profiled crosspieces 4 comprising support wings 5 for the panels 3; These crosspieces, which have the general shape of inverted gutters, are suspended by threaded rods 6 from the ceiling tile 7.
Quatre travées A, 3, C, D du plafond suspendu 1 ont été représentées. A l'aplomb de la travée A se trouve une cloison amovible 8 composés, dans le présent exemple, de deux panneaux 9 et 10 et se terminant par un profilé en U 11 interposé entre les bords supérieurs des panneaux 9 et 10. Ce profilé 11, dont la forme peut varier pour permettre l'adaptation de toutes sortes de cloisons 8, s'emboîte dans un logement de réception qu'offre à cet effet la traverse 4 et qui est formé par des flancs 12 verticaux et des rebords d'appui 13 horizontaux.Le profilé 11 est immobilisé après emboîtement dans la traverse 4 par des boulons 14 se vissant dans de larges écrous 15 soutenus par des nervures 16 qui s'étendent horizontalement et en regard l'une de l'autre et forment une sorte de glissière à la partie supérieure du profilé 4. Four spans A, 3, C, D of the suspended ceiling 1 have been shown. In line with bay A is a removable partition 8 composed, in this example, of two panels 9 and 10 and ending with a U-shaped profile 11 interposed between the upper edges of the panels 9 and 10. This profile 11 , whose shape can vary to allow the adaptation of all kinds of partitions 8, fits into a receiving housing that offers for this purpose the crosspiece 4 and which is formed by vertical sides 12 and support flanges 13 horizontaux.Le profile 11 is immobilized after fitting into the cross 4 by bolts 14 being screwed into large nuts 15 supported by ribs 16 which extend horizontally and facing each other and form a kind of slide at the top of the profile 4.
La cloison 8 est complétée, entre le plafond suspendu et la dalle 7, par une barrière 17. Celle-ci est formée de deux plaques 18 qui reposent dans des étriers doubles 19 surmontant la partie dorsale de la traverse 4 et s'appuyant sur celle-ci, et qui sont tanues à leur partie supérieure entre une pièce d'écartement 20 profilée en U et des pièces de serrage 21, toutes fixées contre la dalle 7 par des écrous 22 vissés sur les tiges filetées 6, lesquelles traversent les pièces 20 et 21 (ce qui n'est pas le cas pour les étriers 19). The partition 8 is completed, between the suspended ceiling and the slab 7, by a barrier 17. This is formed by two plates 18 which rest in double stirrups 19 surmounting the dorsal part of the cross member 4 and resting on that -this, and which are tanu in their upper part between a spacer piece 20 profiled in U and clamping pieces 21, all fixed against the slab 7 by nuts 22 screwed on the threaded rods 6, which pass through the pieces 20 and 21 (which is not the case for stirrups 19).
Pour permettre un montage et un démontage aisé de la barrière 17, la pièce profilée 20 est faite en deux parties 20a, 20b on forme de cornière, pourvues d'encoches 32 de passage des tiges 6 (figure 2). Les pièces de serrage 21 sont des pinces déformables pouvant outre engagées sur les tiges 6 par des encoches 33. La barrière 17 entre les plaques 18 de laquelle peut être placé un matelas 23 de matière isolante telle que de la laine de roche, constitue une barrière phonique et anti-feu amovible, complétant la cloison amovible 8. To allow easy assembly and disassembly of the barrier 17, the profiled part 20 is made in two parts 20a, 20b in the form of an angle iron, provided with notches 32 for passage of the rods 6 (Figure 2). The clamping pieces 21 are deformable clamps which can also be engaged on the rods 6 by notches 33. The barrier 17 between the plates 18 from which a mattress 23 of insulating material such as rock wool can be placed, constitutes a barrier removable sound and fire protection, completing the removable partition 8.
Dans la travée B, il n'y a pas de cloison 8. In bay B, there is no partition 8.
La cavité de réception qu'offre la traverse 4 correspon dante est alors obturés, pour supprimer la solution de continuité qui app@@@@it entre les panneaux 5, par un couvre-Joint 24 profilé amovible qui a'y euboîte et s'enclenche grâce à des pattes élastiques 25 coopérant avec des nervures 26 prévues à l'intérieur de la traverse 4, de sorte que la pose et la dépose du couvre-joint est aisée et rapide.The receiving cavity offered by the corresponding cross-member 4 is then closed, in order to remove the continuity solution which app @@@@ it between the panels 5, by a removable profiled joint cover 24 which has been placed there and snaps into place thanks to elastic tabs 25 cooperating with ribs 26 provided inside the cross-member 4, so that the fitting and removal of the joint cover is easy and quick.
On comprendra aisément, l'examen de la figure 1, qu'il n'y aurait aucune difficulté à transporter, en cas de besoin, la cloison 8 de la travée A à la travée B par exemple. Il suffirait pour cela d'ôter provisoirement les panneaux 9, 10 de la cloison, de désolidariser le profilé 11 de la traverse 4 par dévissage des boulons 14 et de remonter la cloison dans la travée B, avec embottement de son profilé 11 dans la traverse 4 correspondante, le couvre-joint 24 ayant été ôté pour être placé dans la traverse 4 de la travée A. De même, la barrière 17 peut, en ôtant provisoirement certains panneaux 3, être aisément démontée de la travée A, puis remontée dans la travée B. It will be readily understood, examining FIG. 1, that there would be no difficulty in transporting, if necessary, the partition 8 from bay A to bay B for example. It would suffice for this to temporarily remove the panels 9, 10 from the partition, to separate the profile 11 from the cross-member 4 by unscrewing the bolts 14 and to reassemble the partition in the bay B, with its profile 11 embedding in the cross-member 4 corresponding, the cover strip 24 having been removed to be placed in the cross member 4 of the span A. Similarly, the barrier 17 can, by temporarily removing certain panels 3, be easily removed from the bay A, then reassembled in the span B.
Il suffit pour cela d'écarter les branches des pièces 21 pour les amener dans la position de la figure 3 (représentée en traits mixtes sur la figure 1), d'8ter les plaques 18, de desserer les écrous 22, de séparer et d'ôter les cornières 20a, 20b, d'ôter les pinces 21 et de transporter les étriers 19 sur la traverse 4 de la travée
B. Il ne reste plus sur cette travée qu'à engager les pinces 21 et les deux cornières 20a,b sur les tiges filetées 6, à serrer les écroua 22, à placer les plaques 18 dans les étriers 19 et à rabattre les branches des pièces 21 pour qu'elle viennent pincer de nouveau les plaques 18. La barrière 17 complétera alors, en conservant son efficacité d'origine, la cloison 8 dans sa nouvelle position sur la travée B.For this, it suffices to separate the branches of the pieces 21 to bring them into the position of FIG. 3 (shown in phantom in FIG. 1), to remove the plates 18, to loosen the nuts 22, to separate and d '' remove the angles 20a, 20b, remove the clamps 21 and transport the stirrups 19 on the cross 4 of the span
B. It only remains on this span to engage the clamps 21 and the two angles 20a, b on the threaded rods 6, to tighten the nuts 22, to place the plates 18 in the stirrups 19 and to fold down the branches of the parts 21 so that they again pinch the plates 18. The barrier 17 will then complete, while retaining its original efficiency, the partition 8 in its new position on the bay B.
On voit que non seulement le plafond suspendu selon l'invention est compatible avec une cloison amovible, nia qu'il en permet de déplacement aisé et sans aucun dommage ni pour la cloison, ni pour le plafond suspendu. We see that not only the suspended ceiling according to the invention is compatible with a removable partition, nie that it allows easy movement and without any damage either to the partition or to the suspended ceiling.
On a montré dans la travée C que le volume interne due chaque traverse 4 peut être mis à profit pour y faire passer des ctbles 27, soutenus par des étriers 28 qui peuvent être fixés par vis et écrous 29 coopérant avec les nervures 16. On voit aussi la présence de trous 30 dans les flancs de la traverse X et de trous 31 dans la face apparente du couvre-Joint 24, qui permettent d'assurer à travers le plafond suspendu une ventilation du local correspondant. It has been shown in bay C that the internal volume due to each crosspiece 4 can be used to pass cables 27 there, supported by stirrups 28 which can be fixed by screws and nuts 29 cooperating with the ribs 16. We see also the presence of holes 30 in the sides of the cross member X and of holes 31 in the visible face of the joint cover 24, which make it possible to provide ventilation through the suspended ceiling of the corresponding room.
Dans la traverse 4 de la travée D, également pourvus de trous d'aération 30, est monté, de la même manière que les étriers 28 de la travée C, un dispositif d'éclairage 34 à tube fluorescent (le couvre-joint 24 étant ici omis), qui se trouve ainsi intégré au plafond suspendu. In the cross-member 4 of the bay D, also provided with ventilation holes 30, is mounted, in the same manner as the stirrups 28 of the bay C, a lighting device 34 with fluorescent tube (the joint cover 24 being here omitted), which is thus integrated into the suspended ceiling.
