Description

DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTIONTECHNICAL FIELD TO WHICH THE INVENTION REFERS

La présente invention concerne de manière générale le doublage de parois à des fins d'isolation ou d'esthétique. Elle a plus particulièrement trait à un accessoire d'entretoisement placé transversalement entre la paroi à doubler et une cloison de doublage pour maintenir cette dernière à distance de la paroi à doubler.The present invention generally relates to the lining of walls for insulation or aesthetic purposes. It relates more particularly to a bracing accessory placed transversely between the wall to be doubled and a lining wall to keep the latter away from the wall to be doubled.

ARRIERE-PLAN TECHNOLOGIQUEBACKGROUND

Le doublage d'une paroi telle qu'un mur, un plafond ou un toit d'un bâtiment est fréquemment pratiqué, en rénovation ou en construction neuve, pour obtenir ou améliorer l'isolation acoustique ou thermique du bâtiment ou d'une pièce spécifique. A cet effet, une cloison de doublage (contre-cloison ou faux-plafond) est rapportée sur une ossature de doublage qui est elle-même fixée à des éléments de structure de la paroi à doubler, à distance donnée de celle-ci. Une garniture d'isolation thermique et/ou acoustique (souvent appelée complexe d'isolation) est insérée entre la paroi à doubler et la cloison de doublage.The doubling of a wall such as a wall, ceiling or roof of a building is frequently practiced, in renovation or new construction, to obtain or improve the acoustic or thermal insulation of the building or a specific room . For this purpose, a doubling wall (against-partition or false ceiling) is reported on a doubling frame which is itself fixed to structural elements of the wall to be doubled, at a given distance therefrom. A thermal and / or acoustic insulation lining (often called an insulation complex) is inserted between the wall to be doubled and the lining wall.

La garniture d'isolation inclut typiquement, d'une part, une ou plusieurs couches de matériau isolant fibreux tel que de la laine minérale et, d'autre part, au moins une membrane pare-vent ou pare-vapeur. Cette membrane est le plus souvent intercalée entre la couche de matériau fibreux et la cloison de doublage, typiquement accolée à la cloison, éventuellement intercalée entre deux couches de matériau fibreux.The insulation liner typically includes, on the one hand, one or more layers of fibrous insulating material such as mineral wool and, on the other hand, at least one windshield or vapor barrier. This membrane is most often interposed between the layer of fibrous material and the lining wall, typically contiguous to the partition, optionally interposed between two layers of fibrous material.

La fixation de l'ossature de doublage aux éléments de structure de la paroi à doubler est réalisée au moyen d'accessoires d'entretoisement régulièrement espacés. Chaque accessoire d'entretoisement comporte un corps principal en forme de tige s'étendant transversalement à la paroi à doubler et à la cloison de doublage, dont une extrémité est pourvue de moyens de sa fixation en porte-à-faux à un élément de structure de la paroi à doubler et dont l'autre extrémité est pourvue de moyens de son assemblage avec l'ossature de doublage. Un tel accessoire d'entretoisement est par exemple connu du document WO2006/061538 .The attachment of the doubling frame to the structural elements of the wall to be doubled is achieved by means of regularly spaced bracing accessories. Each bracing accessory comprises a rod-shaped main body extending transversely to the wall to be doubled and to the lining wall, one end of which is provided with means for its cantilever attachment to a structural element. the wall to be doubled and the other end is provided with means of its assembly with the backbone. Such a bracing accessory is for example known from the document WO2006 / 061538 .

Lors de l'installation, la garniture d'isolation est embrochée sur les tiges des accessoires d'entretoisement, ce qui provoque un percement multiple des couches de matériau fibreux et le cas échéant de la membrane. Ce percement est particulièrement préjudiciable en ce qui concerne les membranes, car leur fonction d'étanchéité, permanente ou sélective, est alors altérée. Le percement de la membrane peut en outre constituer une amorce de déchirure de nature à se propager si une tension est exercée sur la membrane.When installing, the insulation pad is hooked onto the rods bracing accessories, which causes multiple piercing of the layers of fibrous material and, where appropriate, the membrane. This piercing is particularly detrimental with respect to the membranes, because their sealing function, permanent or selective, is then altered. The piercing of the membrane may further constitute a tear initiation likely to propagate if a tension is exerted on the membrane.

Pour éviter en partie ce problème, il est connu de disposer la membrane du côté intérieur de l'ossature de doublage, entre cette dernière et la cloison de doublage. La membrane n'est ainsi pas traversée par l'accessoire d'entretoise et peut ainsi rester intègre, du moins dans un premier temps.To partially avoid this problem, it is known to arrange the membrane on the inside of the backing frame, between the latter and the lining wall. The membrane is not traversed by the spacer accessory and can remain intact, at least initially.

Cette solution n'est cependant que partielle. La fixation de la cloison de doublage sur l'ossature de doublage implique le percement de la membrane par les éléments de fixation (agrafes, vis, clous, etc.), ce qui nuit, bien que dans une moindre mesure, à l'étanchéité de la membrane.This solution is however only partial. The fixing of the lining wall on the lining frame involves the piercing of the membrane by the fastening elements (staples, screws, nails, etc.), which, although to a lesser extent, impairs the seal of the membrane.

Le positionnement de la membrane devant l'ossature de doublage soulève un autre problème technique : il ne laisse subsister aucun espace interstitiel entre la membrane et la cloison de doublage. Or, il s'avère souvent nécessaire d'insérer, derrière la cloison de doublage, différents câbles ou tuyaux notamment de réseau d'eau, de ventilation, d'électricité ou de communication. Il est alors difficilement envisageable de placer les câbles et accessoires de câblage entre la membrane et la cloison de doublage. Les câbles ne pourraient en effet être convenablement fixés qu'à la faveur d'ouvertures ménagées dans la membrane. La membrane risquerait en outre d'être blessée ou distendue par les câbles ou des accessoires de gainage, fixation ou raccordement.The positioning of the membrane in front of the doubling frame raises another technical problem: it leaves no interstitial space between the membrane and the lining wall. However, it is often necessary to insert, behind the lining wall, various cables or pipes including water network, ventilation, electricity or communication. It is therefore difficult to envisage placing the cables and wiring accessories between the membrane and the lining wall. The cables could indeed be properly fixed only through openings in the membrane. The membrane could also be injured or distended by the cables or accessories cladding, fixing or connection.

Ces câbles peuvent certes être disposés derrière la membrane. Mais il n'est alors plus possible d'y accéder pour la maintenance ou l'évolution de l'installation de câblage sans retirer la membrane ou y pratiquer une ouverture. En outre, les opérations de câblage peuvent, pour des raisons de logistique ou d'évolution des besoins ou des technologies, intervenir postérieurement au doublage de la paroi, ce qui nécessite également la dépose ou l'ouverture de la membrane par des intervenants qui ne sont généralement pas spécialisés dans le doublage de parois et l'isolation.These cables can certainly be arranged behind the membrane. But it is no longer possible to access it for the maintenance or the evolution of the wiring installation without removing the membrane or opening it. In addition, cabling operations may, for reasons of logistics or changes in needs or technologies, occur after the doubling of the wall, which also requires the removal or opening of the membrane by stakeholders who do not are usually not specialized in wall lining and insulation.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Un but de la présente invention est d'offrir une autre solution technique permettant à la fois la préservation pérenne de l'intégrité de la membrane et la réservation d'un volume aisément accessible, derrière la cloison de doublage, pour les câblages.An object of the present invention is to offer another technical solution allowing both the long-term preservation of the integrity of the membrane and the reservation of an easily accessible volume, behind the doubling wall, for wiring.

A cet effet, on propose selon l'invention un accessoire d'entretoisement adapté à la fixation d'une ossature de doublage sur un élément de structure d'une paroi à doubler, comportant une tige s'étendant suivant une direction dite axiale, dont une extrémité est pourvue de moyens de sa fixation à l'élément de structure de la paroi à doubler et dont l'autre extrémité est pourvue de moyens de son assemblage avec l'ossature de doublage, et deux mâchoires entourant la tige et des moyens de verrouillage avec serrage axial de ces deux mâchoires l'une contre l'autre.For this purpose, according to the invention, a bracing accessory is proposed which is suitable for fixing a doubling frame on a structural element of a wall to be doubled, comprising a rod extending in a so-called axial direction, of which one end is provided with means for attaching it to the structural element of the wall to be doubled and the other end of which is provided with means for assembling it with the doubling frame, and two jaws surrounding the rod and means for locking with axial clamping of these two jaws against each other.

Les deux mâchoires pincent ainsi, après verrouillage, la périphérie de l'ouverture d'embrochement de la membrane sur la tige et forment alors une sorte d'oeillet de protection et de limitation de cette ouverture. La largeur de l'ouverture est de ce fait maîtrisée, ce qui permet de limiter, voire de supprimer, la circulation d'air ou de vapeur au travers de l'ouverture d'embrochement de la membrane. De plus, les mâchoires assurent un maintien mécanique de la membrane, ce qui permet en particulier d'éviter les amorces de déchirure de la membrane.The two jaws thus pinch, after locking, the periphery of the skewer opening of the membrane on the rod and then form a sort of eyelet protection and limitation of this opening. The width of the opening is thereby controlled, which allows to limit or eliminate the flow of air or steam through the skew opening of the membrane. In addition, the jaws provide mechanical support of the membrane, which allows in particular to avoid tearing primers of the membrane.

L'invention a également pour objet un dispositif de doublage d'une paroi, comportant

  • au moins un accessoire d'entretoisement comportant une tige, dont une extrémité est pourvue de moyens de sa fixation à un élément de structure de la paroi à doubler et dont l'autre extrémité est pourvue de moyens de son assemblage avec une cloison de doublage,
  • une membrane pare-vent, pare-vapeur ou freine-vapeur à embrocher sur les tiges des accessoires d'entretoisement.
The subject of the invention is also a device for doubling a wall, comprising
  • at least one bracing accessory comprising a rod, one end of which is provided with means for attaching it to a structural element of the wall to be doubled and the other end of which is provided with means for assembling it with a lining partition,
  • a windshield, vapor barrier or vapor barrier to be stuck on the rods of the bracing accessories.

L'un au moins des accessoires d'entretoisement est conforme aux caractéristiques précitées, ses deux mâchoires pinçant entre elles, après verrouillage, la membrane à la périphérie de son ouverture d'embrochement concernée.At least one of the bracing accessories is in accordance with the aforementioned characteristics, its two jaws pinching between them, after locking, the membrane at the periphery of its skewed opening concerned.

Avantageusement, la membrane est maintenue par les mâchoires des accessoires d'entretoisement derrière l'ossature de doublage, à distance de la cloison de doublage. On réserve ainsi, entre la cloison de doublage et la membrane, un espace libre dans lequel il est possible d'installer des câblages ou appareillages sans détériorer la membrane.Advantageously, the membrane is held by the jaws of the bracing accessories behind the lining frame, away from the lining wall. Thus, between the lining partition and the membrane, there is a free space in which it is possible to install wiring or equipment without damaging the membrane.

On se propose, globalement, de réaliser un doublage intérieur d'isolation des parois d'un bâtiment. Dans l'exemple illustré par la figure 1, il s'agit plus spécifiquement d'isoler les combles d'un bâtiment et, à cet effet, de doubler un mur extérieur 1 et une toiture 2 de ce bâtiment.It is proposed, overall, to perform an inner lining insulation of the walls of a building. In the example illustrated by the figure 1 , it is more specifically to isolate the attic of a building and, for this purpose, to double a exterior wall 1 and a roof 2 of this building.

La toiture 2 comporte ici, classiquement, une charpente en bois constituée de pannes 3 portant des chevrons 4 sur lesquels reposent des éléments de couverture 5.The roof 2 here comprises, conventionally, a wooden frame consisting of purlins 3 carrying rafters 4 on which cover elements 5 rest.

Un dispositif de doublage, conforme à l'invention, est rapporté sur la charpente de toit et sur le mur extérieur. Ce dispositif de doublage comporte une ossature de doublage, composée d'une part de lattes horizontales 6 pour le doublage de la toiture et d'autre part de lattes verticales 7 pour le doublage du mur 1. Ces lattes sont communément appelées fourrures.A dubbing device, according to the invention, is attached to the roof frame and the outer wall. This dubbing device comprises a backing frame, consisting on the one hand of horizontal slats 6 for the doubling of the roof and on the other hand vertical slats 7 for doubling the wall 1. These slats are commonly called furs.

Les lattes de doublage 6 et 7 sont respectivement fixées à des éléments de structure de la toiture 2 et du mur 1 à doubler au moyen d'une pluralité d'accessoires d'entretoisement 10, 11.The doubling slats 6 and 7 are respectively fixed to structural elements of the roof 2 and the wall 1 to be doubled by means of a plurality of bracing accessories 10, 11.

En référence aux figures 1 à 3, chaque accessoire d'entretoisement 10, 11 comporte une tige 12 dont une extrémité, dite arrière, est pourvue de moyens de sa fixation en porte-à-faux à la toiture 2 ou au mur 1 et dont l'autre extrémité, dite avant, est pourvue de moyens de son assemblage avec la latte 6, 7 dont l'accessoire assure le maintien. Au montage, la tige 12 est disposée pour s'étendre suivant une direction sensiblement perpendiculaire à la toiture 2 ou au mur 1.With reference to Figures 1 to 3 each bracing accessory 10, 11 comprises a rod 12 whose one end, called the rear end, is provided with means for fixing it cantilevered to the roof 2 or to the wall 1 and whose other end, so-called before , is provided with means of its assembly with the batten 6, 7 whose accessory ensures the maintenance. On assembly, the rod 12 is arranged to extend in a direction substantially perpendicular to the roof 2 or the wall 1.

Les accessoires d'entretoisement 10, également appelés suspentes, servent au doublage de la toiture et sont fixés aux chevrons 4. Ils comportent à cet effet chacun une platine longitudinale de fixation 13 équipant l'extrémité arrière de la tige 12 et vissée sur le flanc du chevron 4 concerné. Les accessoires d'entretoisement 11 sont fixés au mur 1 au moyen d'une platine transversale de fixation 18 solidaire de l'extrémité arrière de la tige et vissée sur le mur 1.The bracing accessories 10, also called lines, are used for doubling the roof and are fixed to the rafters 4. They each comprise for this purpose a longitudinal fixing plate 13 fitted to the rear end of the rod 12 and screwed on the sidewall of the chevron 4 concerned. The bracing accessories 11 are fixed to the wall 1 by means of a transverse fixing plate 18 secured to the rear end of the rod and screwed onto the wall 1.

Selon une caractéristique avantageuse, illustrée par la figure 4, l'accessoire d'entretoisement 10 comporte, avant montage, une enfilade de platines de fixation s'étendant suivant la direction axiale de la tige 12, dans le prolongement de celle-ci. On distingue en l'espèce trois platines, dont la platine 13 et deux autres platines 14, 15. Tout dispositif comportant plus de trois platines ou moyens équivalents présentant notamment douze à quinze trous, est envisageable.According to an advantageous characteristic, illustrated by the figure 4 , the spacer accessory 10 comprises, before mounting, a series of fixing plates extending in the axial direction of the rod 12, in the extension thereof. There are in this case three plates, including the plate 13 and two other plates 14, 15. Any device having more than three plates or equivalent means having in particular twelve to fifteen holes, is possible.

Des zones sécables 16, 17 sont ménagées entre les platines. Ces zones présentent une résistance mécanique réduite en flexion autour de la direction des lattes 6, ce qui permet de détacher les platines 14 ou 15, en forçant manuellement leur flexion ou à l'aide d'une pince coupante, afin d'ajuster la longueur souhaitée. Cette adaptabilité permet en particulier de réduire le nombre de références d'accessoires à fabriquer et à distribuer et d'éviter les erreurs de commande ou de livraison qui, constatées tardivement sur le chantier, retardent l'avancement des travaux.Breakable zones 16, 17 are formed between the plates. These zones have a reduced bending strength around the direction of the slats 6, which allows to detach the plates 14 or 15, manually forcing their bending or using a cutting pliers, to adjust the desired length. This adaptability makes it possible in particular to reduce the number of references of accessories to manufacture and to distribute and to avoid order or delivery errors which, noted late on the construction site, delay the progress of the work.

Chaque accessoire d'entretoisement présente ainsi une longueur hors tout (correspondant à la distance entre ses points extrêmes suivant sa direction longitudinale) typiquement comprise entre 200 et 350 millimètres lorsqu'il est pourvu de toutes ses platines de fixation et entre 80 et 150 millimètres lorsque ne subsiste plus que la dernière platine de fixation.Each bracing accessory thus has an overall length (corresponding to the distance between its end points in its longitudinal direction) typically between 200 and 350 millimeters when it is provided with all its fixing plates and between 80 and 150 millimeters when only the last fixing plate remains.

En variante, l'accessoire d'entretoisement comporte une platine unitaire, par exemple en forme de languette, dotée d'une multiplicité de repères longitudinaux, de préférence constitués par des orifices de vissage, destinés à repérer la position de fixation de l'accessoire sur le chevron. Des lignes de faiblesses favorisant la sécabilité, ou autres repères peuvent avantageusement délimiter des zones sécables.As a variant, the bracing accessory comprises a unitary plate, for example in the form of a tongue, provided with a multiplicity of longitudinal markers, preferably constituted by screw holes, intended to identify the attachment position of the accessory. on the chevron. Lines of weaknesses favoring breakability, or other reference marks may advantageously delimit breakable zones.

Comme cela est illustré par les figures 2 et 3, l'extrémité avant de la tige 12 est équipée de moyens de son assemblage avec la latte correspondante qui est en l'espèce la latte horizontale 6 de doublage de toiture. Ces moyens d'assemblage comportent un chapeau 19, appelé ici clef, rapporté sur l'extrémité avant de la tige 12.As illustrated by the figures 2 and 3 , the front end of the rod 12 is equipped with means of its assembly with the corresponding slat which is in this case the horizontal batten 6 of roof doubling. These assembly means comprise a cap 19, here called key, attached to the front end of the rod 12.

Des moyens de liaison mécanique de ce chapeau avec la tige 12 s'opposent, après engagement, à son retrait vers l'avant mais autorisent son pivotement au moins partiel autour de la tige 12.Means of mechanical connection of this cap with the rod 12 oppose, after engagement, to its withdrawal towards the front but allow its pivoting at least partially around the rod 12.

En l'espèce, ces moyens de liaison mécanique opèrent à la façon d'un clip. Une gorge annulaire 25 est ménagée sur l'extrémité avant de la tige 12 et présente un flanc arrière 26 et un flanc avant 27 formant butées axiales. Le chapeau 19 possède une ouverture centrale 20 d'emmanchement sur l'extrémité avant de la tige 12. Un étranglement 21 est ménagé dans cette ouverture centrale pour être engageable à force, à la façon d'un clip, avec la gorge 25, après franchissement d'un point dur. Ce point dur est matérialisé par une collerette conique 28 ménagée devant la gorge 25 pour former rampe d'encliquetage.In this case, these mechanical connection means operate in the manner of a clip. An annular groove 25 is provided on the front end of the rod 12 and has a rear flank 26 and a front flank 27 forming axial abutments. The cap 19 has a central opening 20 fitting on the front end of the rod 12. A throat 21 is formed in this central opening to be engaged forcefully, like a clip, with the groove 25, after crossing a hard point. This hard point is materialized by a conical flange 28 formed in front of the groove 25 to form a latching ramp.

Les moyens d'assemblage comportent enfin des moyens de liaison clippée à glissière du chapeau 19 avec les lattes 6, 7.The assembly means finally comprise connecting means zipper of the hat 19 with the slats 6, 7.

Chaque latte 6, 7 est ici réalisée sous la forme d'un profilé métallique, ou fourrure, à section en C présentant des rebords rentrants 8, pointant l'un vers l'autre pour s'engager à la façon d'un clip dans une encoche associée 22 du chapeau 19. Pour faciliter l'encliquetage des rebords 8 de la latte dans les encoches 22, le chapeau 19 possède une face avant convexe agissant à la façon d'une rampe pour forcer l'écartement élastique des branches des lattes.Each slat 6, 7 is here made in the form of a metal section, or fur, with a C section having re-entrant edges 8, pointing towards each other to engage in the manner of a clip in an associated notch 22 of the cap 19. To facilitate the snapping of the flanges 8 of the batten in the notches 22, the cap 19 has a convex front face acting in the manner of a ramp to force the elastic separation of the branches of the slats .

La tige 12 de chaque accessoire d'entretoisement 10, 11 est réalisée en matière plastique venue de matière avec les platines de fixation 13, 14, 15 et la gorge 25. Le chapeau 19 est réalisé de la même manière. On peut typiquement utiliser, pour la tige 12 comme pour le chapeau 19, un polymère ou un copolymère tel qu'un polyamide.The rod 12 of each bracing accessory 10, 11 is made of plastic material integrally with the fixing plates 13, 14, 15 and the groove 25. The cap 19 is made in the same way. Typically, for the rod 12, as for the cap 19, a polymer or a copolymer such as a polyamide can be used.

Une cloison de doublage 30, composée de plaques de parement du type plaques de plâtres BA 13, sont rapportées et fixées par vis ou rivets contre le lattis de doublage formé par les lattes 6, 7.A doubling wall 30, composed of facing plates of the BA 13 plasterboard type, is attached and fastened by screws or rivets against the doubling lath formed by the laths 6, 7.

Une garniture d'isolation thermique et/ou acoustique est insérée entre la paroi à doubler (mur 1 et toiture 2) et la cloison de doublage 30. Cette garniture comporte une couche épaisse 31 de matériau isolant fibreux tel que de la laine minérale, d'origine animale ou végétale. Cette couche 31 est constituée d'une succession de panneaux ou de lés de feutre isolants embrochés sur les tiges 12 des accessoires d'entretoisement 10, 11. Ces panneaux ou feutres isolants sont habituellement disponibles en épaisseurs de 65, 75, 85, 100, 200 ou 240 millimètres.A thermal insulation and / or acoustic insulation is inserted between the wall to be doubled (wall 1 and roof 2) and the lining partition 30. This lining comprises a thick layer 31 of fibrous insulating material such as mineral wool, d animal or vegetable origin. This layer 31 consists of a succession of panels or insulating felt strips socketed on the rods 12 of the bracing accessories 10, 11. These insulating panels or felts are usually available in thicknesses of 65, 75, 85, 100, 200 or 240 millimeters.

La garniture d'isolation dudit dispositif de doublage inclut de plus une membrane pare-vent, pare-vapeur ou freine-vapeur 32 étendue contre la couche épaisse isolante 30, entre celle-ci et les lattes 6, 7, et embrochée à cet effet sur les tiges des accessoires d'entretoisement 10, 11. Cette membrane est par exemple du type hygro-régulante, possédant une perméance à la vapeur d'eau variant en fonction de l'humidité ambiante, telle que celles décrites dans les documents FR2884843 et WO96/33321 . L'épaisseur de ce genre de membrane est typiquement comprise entre 5 et 100 micromètres.The insulation lining of said lining device further includes a windshield, vapor barrier or vapor retarder 32 extended against the thick insulating layer 30, between the latter and the slats 6, 7, and skewered for this purpose on the rods of the bracing accessories 10, 11. This membrane is for example of the hygro-regulating type, having a permeance to water vapor varying according to the ambient humidity, such as those described in the documents FR2884843 and WO96 / 33321 . The thickness of this kind of membrane is typically between 5 and 100 micrometers.

L'ensemble de la garniture d'isolation, avec sa couche de matériau fibreux et sa membrane, est communément appelé complexe d'isolation. Il peut, en variante, comporter plusieurs couches de matériau fibreux et plusieurs membranes.The entire insulation liner, with its fibrous material layer and membrane, is commonly referred to as the insulation complex. It may, alternatively, comprise several layers of fibrous material and several membranes.

La membrane 32 est, du fait de son embrochement sur les tiges 12, ajourée autour de chaque accessoire d'entretoisement 10, 11 et il est prévu, selon l'invention, des moyens pour rétablir et pérenniser l'intégrité de la fonction pare-vent, pare-vapeur ou freine-vapeur de cette membrane.The membrane 32 is, because of its skew on the rods 12, perforated around each spacer accessory 10, 11 and is provided, according to the invention, means to restore and sustain the integrity of the protective function. wind, vapor barrier or vapor barrier of this membrane.

Chaque accessoire d'entretoisement comporte à cet effet deux mâchoires annulaires entourant la tige et des moyens de verrouillage avec serrage axial de ces deux mâchoires l'une contre l'autre, ses deux mâchoires pinçant entre elles, après verrouillage, la membrane 32 à la périphérie de son ouverture d'embrochement concernée.Each bracing accessory comprises for this purpose two annular jaws surrounding the rod and locking means with axial clamping of these two jaws against each other, its two jaws pinching between them, after locking, the membrane 32 to the periphery of its skewed opening concerned.

On observe que ce pincement s'opère sur une zone de contact mutuel continue et refermée sur elle-même. Cette zone de contact est en l'espèce, comme les mâchoires, annulaire. On pourra toutefois, en variantes, prévoir d'autres formes de mâchoires formant, dans leur zone de contact mutuel, une boucle complète de forme quelconque autre que circulaire, par exemple, polygonale, ovale, etc.It is observed that this pinching takes place on a zone of continuous mutual contact and closed on itself. This contact zone is in this case, like the jaws, annular. However, it is possible, in variants, to provide other forms of jaws forming, in their zone of mutual contact, a complete loop of any shape other than circular, for example, polygonal, oval, etc.

L'une de ces deux mâchoires est en l'espèce constituée par le chapeau 19 clippé sur l'extrémité avant de la tige 12. Le chapeau 19 exerce donc deux fonctions : une fonction d'assemblage des lattes 6, 7 avec l'accessoire d'entretoisement 10, 11 pour la fixation du lattis de doublage et une fonction palliative de pincement ou "prise en sandwich" de la membrane 32 pour contenir et obturer son ouverture d'embrochement.One of these two jaws is in this case constituted by the cap 19 clipped on the front end of the rod 12. The cap 19 thus has two functions: a function of assembly of the slats 6, 7 with the accessory bracing 10, 11 for fixing the doubling lath and a palliative function of pinching or "sandwiching" of the membrane 32 to contain and seal its skewed opening.

L'autre mâchoire est constituée par une rondelle 34 ayant une ouverture centrale 35 dont le bord est clippé dans la gorge de verrouillage 25 de la tige 12. Cette rondelle 34 est de forme conique et est apte à se déformer élastiquement pour s'aplatir. Cette élasticité propre de la rondelle 34 rappelle celle-ci contre la face arrière 23 du chapeau 19. Elle est en l'espèce réalisée en métal, par exemple en acier doux et inoxydable, mais pourra également être réalisée en matière plastique, comme le chapeau 19 ou en une matière plastique différente.The other jaw is constituted by a washer 34 having a central opening 35 whose edge is clipped into the locking groove 25 of the rod 12. This washer 34 is conically shaped and is able to deform elastically to flatten. This clean elasticity of the washer 34 recalls it against the rear face 23 of the cap 19. It is in this case made of metal, for example mild steel and stainless, but may also be made of plastic, such as the hat 19 or in a different plastic material.

Au montage, la rondelle 34 est emmanchée sur la tige 12 de l'accessoire d'entretoisement 10, 11 après que la couche épaisse isolante 31 a été embrochée sur la tige 12. La rondelle 34 est emmanchée à force pour franchir la collerette 28 de la tige 12 et est alors disposée devant la couche 31, le bord de son ouverture centrale 35 prenant appui contre le flanc arrière 26 de la gorge de verrouillage 25.On mounting, the washer 34 is fitted on the rod 12 of the spacer accessory 10, 11 after the thick insulating layer 31 has been plugged onto the rod 12. The washer 34 is force-fitted to cross the collar 28 of the rod 12 and is then disposed in front of the layer 31, the edge of its central opening 35 bearing against the rear flank 26 of the locking groove 25.

La membrane 32 est ensuite embrochée sur l'extrémité de la tige 12 et plaquée contre la rondelle 34 et la couche 31.The membrane 32 is then plugged onto the end of the rod 12 and pressed against the washer 34 and the layer 31.

Le chapeau 19 est à son tour emmanché à force sur l'extrémité de la tige 12 et comprime la membrane 32 contre la rondelle 34. Cet emmanchement s'effectue à force et l'étranglement 21 du chapeau 19 franchit le point dur matérialisé par la collerette 28. La rondelle 14, qui est initialement conique et dont la périphérie est repoussée par la face arrière plane 23 du chapeau 19, se déforme à l'encontre de son élasticité propre pour s'aplatir et pincer, avec le chapeau 19, la membrane 32 autour de son ouverture d'embrochement. Lorsque le chapeau 19 est dûment clippé sur l'extrémité de la tige 12, la membrane 32 est pincée par la rondelle 34 et le chapeau 19 avec une pression de pincement constante et prédéterminée et avec rattrapage de jeu.The cap 19 is in turn force-fitted on the end of the rod 12 and compresses the membrane 32 against the washer 34. This fitting takes place by force and the constriction 21 of the cap 19 crosses the hard point materialized by the flange 28. The washer 14, which is initially conical and whose periphery is pushed by the flat rear face 23 of the cap 19, deforms against its own elasticity to flatten and pinch, with the cap 19, the membrane 32 around its skewed opening. When the cap 19 is properly clipped on the end of the rod 12, the membrane 32 is pinched by the washer 34 and the cap 19 with a constant and predetermined clamping pressure and with play catch.

Le chapeau 19 et la rondelle 34 sont immobilisés axialement dans la gorge annulaire 25 et la membrane 32 est ainsi maintenue par le chapeau 19 et la rondelle 34 des accessoires d'entretoisement 10, 11, derrière les lattes 6, 7, à distance de la cloison de doublage 30. Un espace libre est ainsi ménagé entre la cloison de doublage et la membrane et il est alors possible d'installer dans cet espace des câblages, tuyaux ou appareillages sans détériorer la membrane.The cap 19 and the washer 34 are immobilized axially in the annular groove 25 and the membrane 32 is thus held by the cap 19 and the washer 34 of the bracing accessories 10, 11, behind the slats 6, 7, at a distance from the doubling partition 30. A free space is thus provided between the lining wall and the membrane and it is then possible to install in this space cabling, pipes or equipment without damaging the membrane.

En variante non représentée, au lieu d'un système d'assemblage par clip, on pourra prévoir que le chapeau 19 coopère avec l'extrémité avant de la tige 12 au moyen d'un système d'assemblage par vissage ou encore du type à baïonnette.In variant not shown, instead of a clip assembly system, it can be provided that the cap 19 cooperates with the front end of the rod 12 by means of a screw connection system or the type to bayonet.

Dans le cas d'un assemblage par un système à verrouillage quart de tour du type baïonnette, le chapeau 19 jouit d'un débattement axial, sous contrainte du rappel élastique exercé par la rondelle 34. Une butée anti-rotation est ménagée sur la tige 12 pour s'opposer au désengagement intempestif du système de verrouillage quart de tour et pour ne pouvoir être franchie qu'à la faveur du débattement axial élastique précité.In the case of an assembly by a quarter-turn locking system of the bayonet type, the cap 19 has an axial displacement, under stress of elastic return exerted by the washer 34. An anti-rotation stop is formed on the rod 12 to oppose the untimely disengagement of quarter-turn locking system and to be able to be crossed only by the aforementioned elastic axial displacement.

Enfin, on pourra également prévoir des moyens pour assurer une étanchéité entre l'une au moins desdites mâchoires dudit accessoire d'entretoisement et la tige de celui-ci.Finally, it may also provide means for sealing between at least one of said jaws of said spacer accessory and the rod thereof.
