Description
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 relates generally to the lining of walls for insulation or aesthetic purposes. It relates more particularly to a spacer accessory placed transversely between the wall to be lined and a lining partition to keep the latter at a distance from the wall to be lined.
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 lining of a wall such as a wall, a ceiling or a roof of a building is frequently practiced, in renovation or in new construction, to obtain or improve the acoustic or thermal insulation of the building or of a specific room. . For this purpose, a lining partition (counter-partition or false ceiling) is attached to a lining framework which is itself fixed to structural elements of the wall to be doubled, at a given distance from the latter. A thermal and / or acoustic insulation lining (often called an insulation complex) is inserted between the wall to be lined and the lining partition.
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 la 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 lining 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 wind barrier or vapor barrier. This membrane is most often interposed between the layer of fibrous material and the lining partition, typically attached 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
Lors de l'installation, la garniture d'isolation, puis la membrane, est généralement 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.During installation, the insulation trim, then the membrane, is generally plugged onto the rods of the spacer accessories, which causes multiple piercing of the layers of fibrous material and, where appropriate, of the membrane. This piercing is particularly detrimental as regards the membranes, because their sealing function, permanent or selective, is then impaired. The piercing of the membrane can also constitute a tear initiation capable of propagating 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'entretoisement et peut ainsi rester intègre, du moins dans un premier temps.To partially avoid this problem, it is known practice to place the membrane on the inside of the lining framework, between the latter and the lining partition. The membrane is thus not crossed by the spacer accessory and can thus 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. Fixing the lining partition to the lining framework involves piercing the membrane by the fastening elements (staples, screws, nails, etc.), which, although to a lesser extent, affects the waterproofing. 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 lining framework raises another technical problem: it does not leave any interstitial space between the membrane and the lining partition. However, it is often necessary to insert, behind the lining partition, various cables or pipes, in particular for the water, ventilation, electricity or communication network. It is then difficult to envisage placing the cables and cabling accessories between the membrane and the lining partition. The cables could in fact be properly fixed only by means of openings made in the membrane. The membrane could also be injured or stretched by cables or sheathing, fixing or connection accessories.
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 placed behind the membrane. However, it is then no longer possible to access it for maintenance or upgrading the cabling installation without removing the membrane or making an opening in it. In addition, the cabling operations may, for reasons of logistics or changing needs or technologies, occur after the lining of the wall, which also requires the removal or opening of the membrane by workers who do not. are generally not specialized in wall lining and insulation.
Un but de la présente invention est d'offrir une solution technique permettant la mise en place d'une membrane sans rupture de son intégrité et de ses performances d'étanchéité.An aim of the present invention is to offer a technical solution allowing the installation of a membrane without breaking its integrity and its performance. sealing.

characterized in that said coupling means comprise sliding means allowing the second jaw to slide in the first jaw to hold said membrane between the two jaws.
Un des avantages de la présente invention et du coulissement de la seconde mâchoire dans la première mâchoire est de simplifier l'accouplage des deux mâchoires. En effet, le coulissement selon l'invention ne nécessite pas de déformation de l'une des mâchoires par rapport à l'autre afin de pouvoir se faire. Ainsi, il est tout à fait possible que la première mâchoire et/ou la seconde mâchoire soit réalisée dans un matériau ayant une faible déformation élastique ou sans déformation élastique.One of the advantages of the present invention and of the sliding of the second jaw in the first jaw is to simplify the coupling of the two jaws. Indeed, the sliding according to the invention does not require deformation of one of the jaws relative to the other in order to be able to take place. Thus, it is quite possible that the first jaw and / or the second jaw is made of a material having a low elastic deformation or without elastic deformation.
Selon un exemple, les moyens de coulissement comprennent au moins une gorge agencée sur la première mâchoire et au moins une ligne saillante agencée sur la seconde mâchoire pour s'insérer dans ladite gorge.According to one example, the sliding means comprise at least one groove arranged on the first jaw and at least one projecting line arranged on the second jaw to fit into said groove.

Selon un exemple, la ligne saillante ou la gorge de la seconde mâchoire est rectiligne.According to one example, the protruding line or the groove of the second jaw is rectilinear.
Selon un exemple, la ligne saillante ou la gorge de la première mâchoire est rectiligne ou périphérique.According to one example, the protruding line or the groove of the first jaw is rectilinear or peripheral.
Selon un exemple, la première mâchoire comprend une surface supérieure, une surface et une paroi latérale utilisée pour porter la ligne saillante ou la gorge, et dans lequel la seconde mâchoire comprend une base à partir de laquelle deux parties saillantes s'étendent, ces parties saillantes comprenant chacune une face extérieure et une face intérieure, les faces intérieures des parties saillantes étant parallèles et portant chacune une gorge ou une ligne saillante.According to one example, the first jaw comprises an upper surface, a surface and a side wall used to carry the protrusion line or the groove, and in which the second jaw comprises a base from which two protrusions extend, these parts. protrusions each comprising an outer face and an inner face, the inner faces of the protrusions being parallel and each carrying a groove or a protruding line.
Selon un exemple, la première mâchoire comprend deux demi-mâchoires agencées et des moyens d'assemblage pour permettre aux deux demi-mâchoires de s'assembler pour former ladite première mâchoire.According to one example, the first jaw comprises two arranged half-jaws and assembly means to allow the two half-jaws to be assembled to form said first jaw.
Selon un exemple, chaque demi-mâchoires agencées comprend une encoche, les demi-mâchoires étant telles que les encoches coopèrent pour former un logement dans lequel la portion principale s'insère.According to one example, each arranged half-jaws comprises a notch, the half-jaws being such that the notches cooperate to form a housing into which the main portion is inserted.

Cette charnière permet aux demi-mâchoires de pivoter selon un axe parallèle à l'axe central de la portion centrale ou selon un axe orthogonal à l'axe central de la portion centrale.In a variant of the examples, the two half-jaws 15 'are secured by a hinge. This hinge can be a strip of deformable material or a hinge and hinge system. This hinge allows the half-jaws to pivot along an axis parallel to the central axis of the central portion or along an axis orthogonal to the central axis of the central portion.
Chaque demi-mâchoire 15' comprend en outre une encoche de sorte que, lorsque les deux demi-mâchoires 15' sont accouplées, ces encoches forment un évidement dans lequel la portion centrale peut s'insérer.Each half-jaw 15 'further comprises a notch so that, when the two half-jaws 15' are mated, these notches form a recess into which the central portion can be inserted.
Dans une autre variante, la seconde mâchoire 17 est agencée pour permettre la fixation d'une ossature. Pour cela, des moyens de fixation 30 d'une ossature sont agencés. Ces moyens consistent, par exemple, en une rainure périphérique 31 ou en deux rainures parallèles agencés sur la seconde mâchoire permettant la fixation d'un profilé en U. En effet, un tel profilé consiste en une feuille métallique ou plastique pliée pour avoir deux bras parallèles permettant d'obtenir une forme en U ou C selon l'orientation dudit profilé. L'extrémité de chaque bras du profilé présente une surépaisseur. Cette surépaisseur est telle qu'elle peut s'insérer dans la rainure pour permettre la fixation dudit profilé.In another variant, the
Alternativement, les moyens de fixation 30 d'une ossature comprennent deux bras parallèles 33. Ces bras s'étendent depuis la seconde mâchoire 17 dans une direction parallèle à l'axe de la portion centrale. Ces bras ont un écartement tel qu'ils peuvent s'insérer dans l'espace présente entre les deux bras d'un profilé en U ou C.Alternatively, the fixing means 30 of a frame comprise two
Les moyens d'installation 13 comprenant une première mâchoire 15 et une seconde mâchoire 17 sont ainsi utilisés pour fixer, attacher une membrane M au dispositif d'entretoisement. L'installation de la membrane se fait postérieurement au procédé de mise en place du dispositif d'entretoisement sur la paroi à doubler.The installation means 13 comprising a
Ce procédé de mise en place comprend une étape de fixation de la portion centrale sur la paroi P à doubler via les moyens de fixation 14 visible à la
Ensuite, une étape de réglage de la longueur de la portion centrale est réalisée si ladite portion centrale 11 est réglable, visible à la
Après cette étape de réglage, une étape consistant à mettre en place l'isolant avec l'aide dudit accessoire d'entretoisement est réalisée. Cet isolant est placé entre la paroi et la première mâchoire. Cette mise en place diffère selon la configuration du dispositif d'entretoisement.After this adjustment step, a step consisting in fitting the insulation with the help of said spacer accessory is carried out. This insulation is placed between the wall and the first jaw. This placement differs depending on the configuration of the spacer device.
Une première manière de poser l'isolant est de l'embrocher sur la tige 12. Cette manière de poser l'isolant est possible si la première mâchoire est une pièce rapportée sur la tige 12. Cet embrochement est réalisé avant la mise en place de la première mâchoire 15.A first way of fitting the insulator is to plug it in on the
Une seconde manière de poser l'isolant consiste à l'agencer afin qu'il prenne appui sur la surface inférieure 150c.A second way of placing the insulation consists in arranging it so that it bears on the
Cette surface inférieure 150c comprend, dans une première option, des dents. Ces dents s'étendent orthogonalement à la surface inférieure 150c. Ces dents permettent d'embrocher l'isolant pour le maintenir.This
Selon une seconde option, le dispositif d'entretoisement 10 comprend une platine supplémentaire fixée à la tige 12. Cette platine comprend une surface sur laquelle l'isolant prend appui.According to a second option, the
Cette seconde manière est possible pour une première mâchoire 15 de matière avec la tige 12 ou rapportée à celle-ci.This second way is possible for a
Dans le cas d'une première mâchoire 15 qui n'est pas faite de matière avec la tige, une étape optionnelle (visible à la
Une autre étape optionnelle (non représentée) pour les deux manières de pose d'un isolant consiste à désassembler la seconde mâchoire de la première mâchoire 15. En effet, le kit du dispositif d'entretoisement comprend une portion centrale, une première mâchoire 15 et une seconde mâchoire 17, ladite seconde mâchoire 17 pouvant être préfixée à la première mâchoire 15.Another optional step (not shown) for the two ways of installing an insulation consists in disassembling the second jaw from the
Le procédé d'attache / de fixation de la membrane consiste alors à se munir de ladite membrane comme visible à la
Dans une seconde étape visible à la
Puis une troisième étape consiste à se munir de la seconde mâchoire 17 et de la placer à côté de la première mâchoire comme visible à la
Une quatrième étape consiste alors à assembler la seconde mâchoire 17 avec la première mâchoire 15. Pour cela, la seconde mâchoire 17 est déplacée pour que les parties saillantes 164 s'insèrent dans les gorges 162. Cette insertion est réalisée pour que la membrane M soit intercalée entre la première mâchoire et la seconde mâchoire. On comprend que la membrane M est intercalée entre les gorges et les parties saillantes comme visible à la
La seconde mâchoire 17 est alors coulissée pour être assemblée à la première mâchoire 15. Idéalement, la seconde mâchoire 17 présente des dimensions telles que la longueur des gorges 162 et la longueur des lignes saillantes 164 soient sensiblement identiques.The
L'avantage de ce dispositif d'entretoisement 10 est de permettre la mise en place de la membrane sans rupture d'intégrité de celle-ci. Effectivement, le fait d'avoir la membrane M placée entre la première mâchoire 15 et la seconde mâchoire 17 entraine son maintien sans nécessiter un perçage de la membrane.The advantage of this
Ce procédé d'attache / de fixation de la membrane est répété pour chaque dispositif d'entretoisement que comprend le dispositif de doublage d'une paroi. En effet, un tel dispositif comprend au moins un dispositif d'entretoisement selon l'invention, une membrane M pare-vent, pare-vapeur ou freine-vapeur à attacher aux accessoires d'entretoisement.This method of attaching / securing the membrane is repeated for each bracing device included in the wall lining device. Indeed, such a device comprises at least one spacer device according to the invention, a wind barrier M membrane, vapor barrier or vapor barrier to be attached to the spacer accessories.
Dans une autre variante visible aux
Alternativement, les moyens de fixation d'une ossature comprennent deux bras parallèles 33. Ces bras s'étendent depuis la seconde mâchoire 17 dans une direction parallèle à l'axe de la portion centrale. Ces bras ont un écartement tel qu'ils peuvent s'insérer dans l'espace présente entre les deux bras d'un profilé en U ou C.Alternatively, the means for fixing a frame comprise two
Bien entendu, la présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art.Of course, the present invention is not limited to the example illustrated but is susceptible of various variants and modifications which will appear to those skilled in the art.
