Description
Le présent exposé concerne le doublage de structures de façon générale, et notamment mais non limitativement, le doublage de charpentes.This presentation relates to the doubling of structures in general, and in particular but not limited to, the doubling of frames.
Le présent exposé concerne en particulier un dispositif d'entretoisement pouvant être utilisé pour la fixation d'une ossature de doublage sur une structure à doubler.The present disclosure relates in particular to a bracing device that can be used for fixing a backing frame to a structure to be doubled.
Le dispositif d'entretoisement selon l'invention est particulièrement adapté pour le doublage de charpentes anciennes, et pour le doublage de toitures dites « monopan ».The bracing device according to the invention is particularly suitable for the doubling of old frameworks, and for the doubling of so-called "monopan" roofs.
De manière connue, le doublage d'une structure fait appel à un système d'habillage qui comprend usuellement une garniture d'isolation thermique et/ou acoustique telle que de la laine minérale, le plus souvent une membrane, par exemple une membrane pare-vapeur, qui est rapportée contre la garniture d'isolation, et des plaques de parement telles que des plaques de plâtre ou des plaques de faux-plafond qui constituent le parement de doublage. Pour fixer les plaques de parement, une ossature métallique faite de profilés est rapportée à distance de la structure à doubler, la garniture d'isolation étant interposée entre la structure à doubler et les profilés.In known manner, the doubling of a structure uses a cladding system which usually comprises a thermal and / or acoustic insulation lining such as mineral wool, most often a membrane, for example a barrier membrane. steam, which is reported against the insulation pad, and facing plates such as plasterboard or false ceiling plates which constitute the cladding facing. To fix the facing plates, a metal frame made of profiles is reported at a distance from the structure to be doubled, the insulation pad being interposed between the structure to be doubled and the profiles.
De manière à faciliter l'installation de la garniture d'isolation et la fixation des profilés, il est connu d'utiliser des dispositifs d'entretoisement qui servent à la fois pour rapporter à distance les profilés, et maintenir en place la garniture d'isolation et la membrane.In order to facilitate the installation of the insulating lining and the fixing of the profiles, it is known to use bracing devices which are used for times to remotely report the profiles, and keep in place the insulation pad and membrane.
La demande de brevet
Ce type de dispositif n'est pas bien adapté à certains chantiers sur lesquels la hauteur entre la structure à doubler et le doublage n'est pas la même sur toute l'étendue à doubler.This type of device is not well suited to some sites on which the height between the structure to be doubled and the doubling is not the same over the entire area to double.
C'est le cas par exemple des anciennes charpentes : au fil des années, le bois qui constitue les chevrons de ces charpentes a travaillé, c'est-à-dire qu'il s'est déformé. Les chevrons, sur lesquels les dispositifs d'entretoisement doivent être fixés pour le doublage, sont donc souvent tordus ou courbés.This is the case, for example, of old structures: over the years, the wood that forms the rafters of these frames has worked, that is to say, it has been deformed. The rafters, on which the bracing devices must be fixed for the doubling, are therefore often twisted or bent.
C'est également le cas de certaines maisons contemporaines, à toitures dites « monopan » : ces toitures peuvent avoir une différence de hauteur entre le haut et le bas du rampant allant jusqu'à 20 cm.This is also the case for some contemporary houses, with so-called monopan roofs: these roofs can have a difference in height between the top and the bottom of the rampant up to 20 cm.
Dans ce type de cas, l'opérateur doit prévoir plusieurs références du dispositif d'entretoisement, de longueurs adaptées, pour réaliser le doublage. Il lui est nécessaire de réaliser des calculs préalables afin d'évaluer le nombre de suspentes de chaque longueur à prévoir, ou d'emmener sur chantier un surplus de matériel, ce qui peut s'avérer couteux et encombrant.In this type of case, the operator must provide several references of the spacer device, of suitable lengths, to perform the doubling. It is necessary to perform preliminary calculations to estimate the number of lines of each length to provide, or to bring on-site surplus equipment, which can be expensive and cumbersome.
L'un des objectifs de la présente invention est de fournir un système permettant de remédier aux inconvénients précités.One of the objectives of the present invention is to provide a system for overcoming the aforementioned drawbacks.
Cet objectif est atteint avec un dispositif d'entretoisement pour la fixation d'une ossature de doublage sur une structure à doubler, notamment sur une charpente, ledit dispositif comportant
- un corps principal comprenant
- une tige, notamment adaptée pour recevoir une membrane embrochée sur celle-ci, s'étendant suivant une direction dite axiale, et
- une base de fixation à la structure à doubler, à une extrémité arrière de la tige, et
- une pièce de raccord munie de moyens de fixation à l'ossature de doublage, adaptée pour être assemblée à une extrémité avant de la tige,
- a main body comprising
- a rod, in particular adapted to receive a membrane skewed thereon, extending in a so-called axial direction, and
- a fastening base to the structure to be doubled, at a rear end of the rod, and
- a connecting piece provided with fixing means to the backing frame, adapted to be assembled at a front end of the rod,
Le dispositif d'entretoisement selon l'invention est un dispositif réglable en longueur. Grâce au mécanisme de réglage de la longueur du corps, l'opérateur peut utiliser le même dispositif d'entretoisement pour différentes hauteurs de doublage.The bracing device according to the invention is a device adjustable in length. Thanks to the mechanism of adjustment of the length of the body, the operator can use the same bracing device for different doubling heights.
Par ailleurs, le mécanisme de réglage étant échelonné selon un pas grossier, le réglage se fait rapidement. L'opérateur ne peut choisir qu'entre les différentes positions de réglage, régulièrement espacées. Un calcul simple lui permet d'ajuster le dispositif à la longueur souhaitée.Furthermore, the adjustment mechanism being staggered in a coarse pitch, adjustment is done quickly. The operator can only choose between the different setting positions, evenly spaced. A simple calculation allows him to adjust the device to the desired length.
La membrane est avantageusement une membrane d'étanchéité à l'air et/ou de gestion de la vapeur d'eau, de préférence une membrane assurant à la fois ces deux fonctions. La membrane de gestion de la vapeur d'eau est avantageusement une membrane pare-vapeur ou une membrane hygrorégulante, c'est-à-dire dont la perméance à la vapeur d'eau varie en fonction de l'humidité relative ambiante.The membrane is advantageously an airtightness membrane and / or water vapor management, preferably a membrane ensuring both these functions. The water vapor management membrane is advantageously a vapor barrier membrane or a hygroregulating membrane, that is to say whose permeance to water vapor varies as a function of the ambient relative humidity.
On entend par le terme « embrochée » que la tige traverse le plan de la membrane, avec ou sans perçage préalable de ladite membrane. La membrane peut donc être percée préalablement à l'embrochement, la tige passant alors dans l'ouverture réalisée par ce perçage préalable. Alternativement, la membrane peut ne pas être percée préalablement à l'embrochement, l'ouverture étant alors réalisée par la tige elle-même au moment de l'embrochement. Dans tous les cas, l'ouverture par laquelle passe la tige sera appelée dans la suite du texte « ouverture d'embrochement », qu'elle soit créée par l'embrochement ou préalablement à ce dernier.The term "skewered" means that the rod passes through the plane of the membrane, with or without prior drilling of said membrane. The membrane can be pierced before the skewer, the rod then passing into the opening made by this prior drilling. Alternatively, the membrane may not be pierced prior to skew, the opening being then performed by the rod itself at the time of skewering. In all cases, the opening through which the stem passes will be called in the following text "opening skew", whether created by the skewer or prior to the latter.
Selon un exemple, le dispositif d'entretoisement comprend en outre des moyens de blocage en rotation de la base de fixation et de la tige, dans la deuxième position angulaire.In one example, the bracing device further comprises means for locking in rotation of the fixing base and the rod, in the second angular position.
Selon un exemple, les moyens de blocage comprennent des moyens de clipsage.In one example, the locking means comprise clipping means.
Selon un exemple, la base de fixation comporte une partie de réglage adaptée pour recevoir la tige et munie d'une pluralité de crans espacés axialement du pas grossier P, et la tige comporte des ergots ménagés à sa périphérie et adaptés pour coopérer avec lesdits crans.According to one example, the fixing base comprises a setting portion adapted to receive the rod and provided with a plurality of notches spaced axially from the coarse pitch P, and the rod comprises lugs formed at its periphery and adapted to cooperate with said notches .
Selon un exemple, les moyens de clipsage comprennent une languette de clipsage délimitant un cran de la partie de réglage dit cran de blocage, adaptée pour se déplacer en coopérant avec un ergot de la tige lors d'une rotation de la première à la deuxième position angulaire et pour empêcher le retour de l'ergot, une fois la deuxième position angulaire atteinte.According to one example, the clipping means comprise a clipping tab delimiting a notch of the adjusting portion, said locking notch, adapted to move cooperatively with a lug of the rod during a rotation of the first to the second position. angular and to prevent the return of the pin, once the second angular position reached.
De préférence, le dispositif comprend des moyens permettant le retour dans la première position angulaire sous l'effet d'un mouvement de rotation relatif de la tige et de la base de fixation, ou de l'effet combiné d'une translation et d'une rotation relatives de la tige et de la base de fixation.Preferably, the device comprises means allowing the return to the first angular position under the effect of a relative rotational movement of the rod and the base of attachment, or the combined effect of a translation and of a relative rotation of the rod and the fixing base.
Selon un exemple, la tige présente au moins une rainure axiale et la partie de réglage présente au moins une surépaisseur interne située au voisinage de son extrémité avant, et adaptée pour coulisser dans ladite rainure lorsque la tige et la partie de réglage sont dans la première position angulaire. Ces dispositions permettent à l'opérateur d'identifier aisément la première position angulaire, dans laquelle la longueur du corps peut être réglée par coulissement relatif de la tige et de la base de fixation.According to one example, the rod has at least one axial groove and the adjustment portion has at least one internal extra thickness located in the vicinity of its front end, and adapted to slide in said groove when the rod and the adjustment part are in the first angular position. These arrangements allow the operator to easily identify the first angular position, in which the length of the body can be adjusted by relative sliding of the rod and the fixing base.
Selon un exemple avantageux, la tige présente en outre une pluralité de rainures circonférentielles s'étendant depuis la rainure axiale et parallèles entre elles, la surépaisseur interne de la partie de réglage étant adaptée pour pénétrer dans l'une desdites rainures circonférentielles lors du passage de la première à la deuxième position angulaire. Ces dispositions permettent à l'opérateur d'accéder plus facilement aux positions de réglage du dispositif.According to an advantageous example, the rod furthermore has a plurality of circumferential grooves extending from the axial groove and parallel to each other, the internal excess thickness of the adjusting portion being adapted to penetrate into one of said circumferential grooves during the passage of the groove. the first to the second angular position. These provisions allow the operator easier access to the setting positions of the device.
Selon un exemple, la tige présente un tronçon supérieur de sécurité dépourvu de rainures circonférentielles. Grâce à ces dispositions, l'opérateur est empêché de réaliser un montage dans lequel la tige et la partie de réglage ne coopéreraient que sur une très faible longueur, insuffisante pour reprendre les efforts de flexion.In one example, the rod has an upper safety section without circumferential grooves. Thanks to these provisions, the operator is prevented from making an assembly in which the rod and the adjustment part cooperate only over a very short length, insufficient to take up the bending forces.
De préférence, pour assurer une résistance à la flexion suffisante, le tronçon supérieur de sécurité s'étend sur une longueur correspondant à au moins trois fois le pas de réglage grossier.Preferably, to ensure sufficient bending resistance, the upper safety section extends over a length corresponding to at least three times the coarse pitch.
Selon un exemple, la base de fixation comporte une platine de fixation munie de trous pour sa fixation à la structure à doubler.In one example, the fixing base comprises a fixing plate provided with holes for fixing it to the structure to be doubled.
Selon un exemple, les moyens de fixation à l'ossature de doublage comprennent des moyens de liaison clippée à glissière de la pièce de raccord avec un profilé, notamment une encoche formée sur la pièce de raccord et adaptée pour recevoir des rebords rentrants du profilé à la façon d'un clip.According to one example, the fixing means to the backing frame comprise clipping means zipper of the connecting piece with a profile, in particular a notch formed on the connecting piece and adapted to receive re-entrant edges of the profile to the way of a clip.
Selon un exemple, le dispositif d'entretoisement comprend une première et une deuxième mâchoire à la périphérie de la tige, et des moyens de verrouillage avec serrage axial des deux mâchoires l'une contre l'autre, de sorte que celle-ci pincent entre elles, après verrouillage, la membrane à la périphérie de son ouverture d'embrochement sur la tige. La fonction d'étanchéité à l'air assurée par la membrane est ainsi rétablie et/ou pérennisée.According to an example, the spacer device comprises a first and a second jaw at the periphery of the rod, and locking means with axial clamping of the two jaws against each other, so that it clamps between they, after locking, the membrane at the periphery of its skewer opening on the rod. The function of airtightness ensured by the membrane is thus restored and / or perpetuated.
Selon un exemple, les mâchoires présentent, après verrouillage, une zone de contact mutuel continue et refermée sur elle-même.In one example, the jaws have, after locking, a zone of continuous mutual contact and closed on itself.
Selon un exemple, le dispositif d'entretoisement comprend des moyens d'immobilisation de la deuxième mâchoire en translation au moins dans la direction de la structure à doubler.According to one example, the spacer device comprises means for immobilizing the second jaw in translation at least in the direction of the structure to be doubled.
Ces moyens d'immobilisation peuvent par exemple comprendre une butée axiale agencée sur la tige pour s'opposer à l'enfoncement de la deuxième mâchoire en direction de de la structure à doubler.These immobilizing means may for example comprise an axial abutment arranged on the rod to oppose the depression of the second jaw towards the structure to be doubled.
Selon un exemple, la première mâchoire est formée par la pièce de raccord.In one example, the first jaw is formed by the connecting piece.
Selon un exemple, la deuxième mâchoire est formée par une rondelle disposée à la périphérie de la tige. La rondelle peut par exemple être montée à la périphérie de la tige ou être d'un seul tenant avec la tige.In one example, the second jaw is formed by a washer disposed at the periphery of the rod. The washer can for example be mounted on the periphery of the rod or be in one piece with the rod.
Selon un exemple, la pièce de raccord coopère avec l'extrémité avant de la tige au moyen d'un système d'assemblage par rotation quart de tour du type à baïonnette.In one example, the connecting piece cooperates with the front end of the rod by means of a bayonet-type quarter-turn rotation connection system.
Selon un exemple, la pièce de raccord présente au moins une nervure d'assemblage, et la tige comporte à son extrémité avant au moins une rainure d'assemblage comprenant un tronçon d'engagement s'étendant axialement et un tronçon circonférentiel s'étendant depuis ledit tronçon d'engagement, et adapté pour coopérer avec la nervure d'assemblage lors de la rotation quart de tour, le tronçon circonférentiel présentant un rétrécissement de largeur en éloignement du tronçon d'engagement, ce par quoi la nervure d'assemblage est progressivement serrée dans la rainure d'assemblage au fur et à mesure de la rotation quart de tour. Au fur et à mesure de la rotation, l'opérateur sent une résistance croissante qui lui indique la progression de l'assemblage.According to one example, the connecting piece has at least one connecting rib, and the rod comprises at its front end at least one assembly groove comprising an axially extending engagement section and a circumferential section extending from said engagement section, and adapted to cooperate with the connecting rib during the quarter-turn rotation, the circumferential section having a narrowing of width away from the engagement section, whereby the assembly rib is progressively tightened in the assembly groove as it rotates quarter turn. As the rotation progresses, the operator feels increasing resistance indicating the progress of the assembly.
Selon un exemple, le tronçon circonférentiel comprend une butée de fin de course avec laquelle la nervure de la pièce de raccord peut venir en contact à l'issue de la rotation. Le contact entre la nervure et cette butée de fin de course identifie la fin de l'assemblage.In one example, the circumferential section comprises an end stop with which the rib of the coupling piece can come into contact at the end of the rotation. The contact between the rib and this limit stop identifies the end of the assembly.
Selon un exemple, la pièce de raccord présente une ouverture centrale par laquelle elle est adaptée pour être assemblée sur la tige et au moins une ailette souple en saillie dans ladite ouverture, ladite ailette étant adaptée pour s'encliqueter dans une rainure de la tige, notamment en produisant un son, lorsque la pièce de raccord est assemblée sur la tige. L'encliquetage de l'ailette dans la rainure de la tige est pour l'opérateur un témoin du bon assemblage de la pièce de raccord sur la tige.According to one example, the coupling piece has a central opening by which it is adapted to be assembled on the rod and at least one flexible fin projecting into said opening, said fin being adapted to snap into a groove of the rod, in particular by producing a sound, when the connecting piece is assembled on the rod. The snap of the fin in the groove of the rod is for the operator a witness of the proper assembly of the connecting piece on the rod.
Selon un exemple, le dispositif d'entretoisement comprend en outre un mécanisme de réglage fin du positionnement de la pièce de raccord sur la tige, dans la direction axiale.In one example, the bracing device further comprises a mechanism for fine adjustment of the positioning of the coupling piece on the rod, in the axial direction.
Selon un exemple, le mécanisme de réglage fin est échelonné selon un pas fin p inférieur au pas grossier P, notamment selon un pas fin p compris entre 0,1 et 5 mm, notamment entre 0,2 et 2 mm, et plus particulièrement entre 0,5 et 1,5 mm.According to an example, the fine adjustment mechanism is staggered according to a fine pitch p less than the coarse pitch P, in particular according to a fine pitch p between 0.1 and 5 mm, in particular between 0.2 and 2 mm, and more particularly between 0.5 and 1.5 mm.
Selon un exemple, la tige est munie, à son extrémité avant, d'un tronçon de réglage fin muni à sa périphérie d'une pluralité de nervures primaires, et la pièce de raccord est munie d'au moins une nervure secondaire adaptée pour coopérer avec les nervures primaires de la tige pour le blocage en translation de la pièce de raccord par rapport à la tige.According to one example, the rod is provided, at its front end, with a fine adjustment section provided at its periphery with a plurality of primary ribs, and the connecting piece is provided with at least one secondary rib adapted to cooperate. with the primary ribs of the rod for locking in translation of the connecting piece relative to the rod.
Selon un exemple, l'extrémité distale de la tige est adaptée pour embrocher une membrane. Elle présente avantageusement une forme de pointe, utile notamment lorsque la membrane n'est pas percée préalablement à l'embrochement.In one example, the distal end of the rod is adapted to skewer a membrane. It advantageously has a tip shape, useful especially when the membrane is not pierced prior to skewering.
Selon un exemple, la pièce de raccord est pourvue de moyens d'agrippement à sa périphérie, notamment d'une pluralité d'encoches, par exemple semi-circulaires, réparties régulièrement dans la direction circonférentielle.According to one example, the connecting piece is provided with gripping means at its periphery, in particular a plurality of notches, for example semi-circular, regularly distributed in the circumferential direction.
Le présent exposé concerne également un doublage d'une structure, comprenant
- une pluralité de dispositifs d'entretoisement tels que définis précédemment,
- au moins une couche d'isolant thermique et/ou acoustique embrochée sur ou intercalée entre les éléments d'entretoisement, et
- au moins une membrane embrochée sur les dispositifs d'entretoisement.
- a plurality of spacer devices as defined above,
- at least one layer of thermal and / or acoustic insulation skewed on or interposed between the bracing elements, and
- at least one membrane plugged on the bracing devices.
La membrane est avantageusement une membrane d'étanchéité à l'air et/ou de gestion de la vapeur d'eau, de préférence une membrane assurant à la fois ces deux fonctions. La membrane de gestion de la vapeur d'eau est avantageusement une membrane pare-vapeur ou une membrane hygrorégulante, c'est-à-dire dont la perméance à la vapeur d'eau varie en fonction de l'humidité relative ambiante.The membrane is advantageously an airtightness membrane and / or water vapor management, preferably a membrane ensuring both these functions. The water vapor management membrane is advantageously a vapor barrier membrane or a hygroregulating membrane, that is to say whose permeance to water vapor varies as a function of the ambient relative humidity.

Un dispositif d'entretoisement 100 selon l'invention est destiné à être utilisé notamment pour le doublage d'une charpente C, comme représenté sur la
De manière connue, le doublage d'une charpente C comprend une pluralité de dispositifs d'entretoisement 100 fixés sur les chevrons CH de la charpente C, une garniture d'isolation G embrochée sur les dispositifs d'entretoisement ou intercalée entre les dispositifs d'entretoisement, au moins une membrane M, et une ossature de doublage sous forme de profilés de fixation F pour plaques de parement R. La membrane M est généralement une membrane d'étanchéité à l'air et/ou de gestion de la vapeur d'eau. Il peut notamment s'agir d'une membrane pare-vapeur ou d'une membrane hygrorégulante, c'est-à-dire dont la perméance à la vapeur d'eau varie en fonction de l'humidité relative ambiante.In known manner, the doubling of a frame C comprises a plurality of bracing
Dans l'exemple particulier illustré sur la
Sur toute la largeur du rampant, le doublage est ici réalisé avec des dispositifs d'entretoisement 100 selon la présente invention, réglés chacun à une longueur différente adaptée, comme il sera décrit plus en détail dans la suite.Over the entire width of the rampant, the doubling is here carried out with bracing

La tige 20 est ici munie d'une extrémité avant 20a pointue permettant le percement de la membrane M lors de son embrochement sur la tige 20. Dans cet exemple particulier, la membrane M n'est en effet pas percée préalablement à l'embrochement.The
Dans le présent exposé, on désigne l'arrière d'une pièce comme son côté le plus proche de la structure à doubler, et l'avant de la même pièce, comme son côté le plus proche de l'ossature de doublage, en position assemblée.In this presentation, the back of a room is designated as its nearest side of the structure to be doubled, and the front of the same room, as its nearest side of the doubling frame, in position Assembly.
Selon l'invention, le dispositif d'entretoisement 100 comprend un mécanisme de réglage par échelons de la longueur L du corps 10, permettant d'adapter cette longueur L et donc dans le même temps l'espacement entre les moyens de fixation de la base de fixation 40 et la pièce de raccord 60, à la hauteur prévue du doublage. Par exemple, la longueur L du corps 10 peut varier grâce au mécanisme de réglage d'une valeur comprise entre 5 et 20 cm.According to the invention, the bracing
Le réglage de longueur est effectué par coulissement relatif de la base de fixation 40 et de la tige 20 dans la direction axiale X1, puis blocage en translation axiale par rotation relative des deux pièces 20, 40. Le blocage en translation se fait dans une parmi plusieurs positions de réglage possibles, échelonnées selon un pas grossier P compris entre 0,5 et 5 cm, de préférence entre 0,5 et 2 cm, encore plus préférentiellement entre 0,8 et 1,3 cm, par exemple égal à 1 cm, comme décrit plus en détail dans la suite.The length adjustment is made by relative sliding of the fixing
La tige 20 présente typiquement une longueur totale L1 comprise entre 20 et 40 cm. Elle est par exemple réalisée dans un matériau polymère, par exemple du polyamide, éventuellement renforcé intérieurement par une âme métallique.The
Sur la majeure partie de sa longueur L1, et en particulier sur sa portion arrière, la tige 20 présente une partie centrale 22 de section circulaire à diamètre constant.Over most of its length L1, and in particular on its rear portion, the
Sur sa portion arrière, la tige 20 est munie, à la périphérie de cette partie centrale, d'une pluralité d'ergots 24 régulièrement espacés du pas P.On its rear portion, the
Dans l'exemple particulier représenté, la tige comporte en réalité deux rangées diamétralement opposées d'ergots 24 identiques ou similaires, alignés axialement et régulièrement espacés du pas P (ici dix pour chaque rangée).In the particular example shown, the rod actually comprises two diametrically opposed rows of
Entre ces deux rangées d'ergots 24, la tige 20 présente en outre deux rainures 26 diamétralement opposées, chacune d'elles étant rectiligne et continue jusqu'à l'extrémité arrière de la tige, et s'étendant dans la direction axiale X1. Seule l'une de ces rainures 26 est visible sur la
Comme illustré sur la
A noter que par rainure/tronçon de rainure circonférentiel(le), on entend dans le présent exposé une rainure ou un tronçon de rainure s'étendant sur toute ou partie seulement de la circonférence de l'élément portant ladite rainure.Note that by groove / section of circumferential groove (1c), is meant in the present description a groove or a groove section extending over all or only part of the circumference of the element carrying said groove.
La base de fixation 40 comporte, dans l'exemple, une platine de fixation 42 pourvue de trous 44 pour sa fixation par vissage à la structure à doubler. La platine de fixation présente une longueur L2 par exemple comprise entre 5 et 15cm.The fixing
Avantageusement, elle peut présenter au moins un trou oblong 44a tel qu'illustré sur les
L'exemple de la platine de vissage 42 n'est cependant pas limitatif, les moyens de fixation à la structure à doubler pouvant prendre d'autres formes, par exemple des moyens adaptés à une fixation par clouage, ou encore des encoches adaptées pour coopérer par clipsage avec un profilé préalablement fixé sur la structure à doubler, notamment adaptées pour recevoir des rebords rentrant dudit profilé. Il peut s'agir de profilés métalliques, de préférence en C, appliqués sur la structure à doubler (mur maçonné ou éléments de charpente) avec le fond du C tourné vers la structure à doubler et l'ouverture du C tournée vers le doublage à recevoir. Les moyens de fixations à la structure peuvent aussi prendre une autre forme emboitable ou encliquetable avec une forme correspondante sur une latte ou autre profil rapporté sur la structure à doubler.The example of the screwing
La base de fixation 40 est en outre munie d'une partie de réglage 46 de forme tubulaire s'étendant selon un deuxième axe X2 et solidaire des moyens de fixation à la structure à doubler, ici la platine de fixation 42. La partie de réglage 46 forme ici un tube creux adapté pour recevoir intérieurement la tige 20, les axes X1 et X2 étant alors confondus. Elle comporte pour cela une partie centrale 48 de section interne circulaire, de diamètre légèrement supérieur à celui de la tige, et deux logements diamétralement opposés 50a, 50b s'ouvrant sur ladite partie centrale 48 et s'étendant axialement, destinés à recevoir les ergots 24 de la tige 20 dans une première position angulaire.The fixing

Plus particulièrement, la partie de réglage 46 comporte ici deux rangées de respectivement douze crans 52, diamétralement opposées.More particularly, the
Dans l'exemple, les crans 52 sont des trous débouchants, ce qui permet au poseur de visualiser le réglage. Selon une variante toutefois, les crans 52 pourraient être formés par des évidements non traversants pratiqués sur la paroi interne de la partie de réglage 46.In the example, the
Dans le même temps, la partie de réglage 46 présente (voir
Dans la première position, la tige 20 est adaptée pour coulisser axialement dans la partie de réglage 46, de façon à régler la longueur totale L du corps 10.In the first position, the
Une rotation relative de la tige 20 et de la base de fixation 40 est permise lorsque chaque ergot 24 de la tige 20 situé à l'intérieur de la partie de réglage 46 est positionné axialement en regard d'un cran 52 de cette même partie 46, et que chaque surépaisseur interne 54 de la partie de réglage 46 est positionnée axialement en regard de l'une des rainures circonférentielles 28 de la tige 20. Les positions correspondantes sont appelées, dans la suite, positions de réglage.Relative rotation of the
Dans ces positions de réglage, la tige 20 et la base de fixation 40 peuvent pivoter, dans un sens de rotation, de façon à faire pénétrer les ergots 24 de la tige 20 dans les crans 52 de la partie de réglage 46.In these adjustment positions, the
On comprend que dans toute autre position axiale relative des deux pièces, une rotation est impossible, les surépaisseurs 54 de la partie de réglage 46 venant buter contre les parois des rainures axiales 26, et les ergots 24 étant retenus dans les logements 50a, 50b de la partie de réglage 46.It is understood that in any other relative axial position of the two parts, a rotation is impossible, the
La tige 20 présente de préférence un tronçon supérieur de sécurité 30 dépourvu de rainures circonférentielles 28, s'étendant avantageusement sur une longueur L3 correspondant à au moins trois fois le pas de réglage grossier P. Dans l'exemple illustré sur la
La base de fixation 40 et la tige 20 sont maintenues en position après réglage de la longueur L du corps 10 grâce à des moyens de blocage en rotation des deux éléments dans la deuxième position angulaire.The fixing
Ces moyens de blocage comportent ici des moyens mécaniques avec butée, et plus particulièrement des moyens de clipsage, qui seront décrits plus en détail dans la suite.These locking means here comprise mechanical means with stop, and more particularly clipping means, which will be described in more detail below.
Dans la suite du présent exposé, on désigne par crans de blocage 52a les crans ayant une fonction de blocage en rotation et par crans intermédiaires 52b les crans assurant exclusivement une fonction de blocage en translation.In the remainder of the present description, locking
De façon générale, tout cran forme un logement s'étendant dans une direction circonférentielle, et présentant, dans cette direction, une première extrémité 31a par laquelle un ergot 24 de la tige 20 s'écartant de la première position angulaire pénètre dans le cran, et une deuxième extrémité 31b vers laquelle le même ergot 24 se dirige au cours de la rotation de la première à la deuxième position angulaire.In general, any notch forms a housing extending in a circumferential direction, and having, in this direction, a

Un espace libre 35 situé du côté de la languette 34 opposée au cran permet à la languette de se déplacer vers ledit côté sous la pression exercée par l'ergot 24 déplacé dans le cran lors d'une rotation de la première à la deuxième position angulaire.A
La languette 34 présente en outre des propriétés d'élasticité lui permettant de revenir automatiquement dans sa position initiale où elle forme une butée anti-retour pour l'ergot, une fois la deuxième position angulaire atteinte.The
Comme illustré sur la
Au-delà de cet étranglement 36a, le tronçon d'engagement 36 est prolongé par un tronçon de blocage 37 adapté pour recevoir l'ergot 24 une fois la deuxième position angulaire atteinte.Beyond this
Dans l'exemple, le dispositif 100 comprend en outre des moyens permettant le retour dans la première position angulaire sous l'effet d'un mouvement de rotation relatif de la tige 20 et de la base de fixation 40, ou de l'effet combiné d'une translation et d'une rotation relatives de la tige 20 et de la base de fixation 40, comme expliqué ci-après.In the example, the
Pour cela, comme illustré sur la figure, la languette 34 comporte dans le tronçon de blocage 37 une rampe de déblocage 34d, et la paroi opposée 33 présente de la même manière une rampe de déblocage 33d, les deux rampes 33d, 34d convergeant l'une vers l'autre en direction du tronçon d'engagement 36. Alternativement, la languette 34 peut ne comporter qu'une rampe de déblocage 33d ou 34d.For this, as illustrated in the figure, the

La pièce de raccord 60 est rapportée sur l'extrémité avant 20a de la tige 20 et présente pour cela une ouverture centrale d'emmanchement 62. Avantageusement, elle coopère avec l'extrémité avant 20a de la tige 20 au moyen d'un système d'assemblage par rotation quart de tour, du type à baïonnette.The connecting

La pièce de raccord 60 remplit une première fonction d'assemblage d'un profilé de l'ossature de doublage avec l'accessoire d'entretoisement, pour la fixation du parement de doublage.The connecting
Comme il est bien connu, un tel profilé (aussi appelé latte ou fourrure), est généralement métallique et présente une section en C avec des rebords rentrants pointant l'un vers l'autre.As is well known, such a profile (also called batten or fur), is generally metallic and has a C-section with re-entrant edges pointing towards each other.
La pièce de raccord 60 est avantageusement munie d'au moins une encoche 67 adaptée pour recevoir ces rebords et coopérer avec eux selon une liaison à glissière.The connecting
Dans l'exemple illustré, l'encoche 67 est circonférentielle continue et refermée sur elle-même. Pour faciliter l'encliquetage, la pièce de raccord 60 possède une face avant convexe 68 agissant à la façon d'une rampe pour forcer l'écartement élastique des branches du profilé.In the example illustrated, the
La membrane M est, du fait de son embrochement sur la tige 20, ajourée autour du dispositif d'entretoisement 100. Comme expliqué précédemment, une ouverture d'embrochement par laquelle passe la tige 20 est en effet créée, soit par l'embrochement, comme dans l'exemple illustré ici, soit préalablement à l'embrochement. Cette ouverture étant susceptible de compromettre la fonction d'étanchéité à l'air de la membrane M, des moyens peuvent toutefois être prévus pour rétablir et/ou pérenniser l'intégrité de la fonction d'étanchéité de cette membrane M.The membrane M is, because of its skewering on the
Ces moyens comprennent ici deux mâchoires annulaires entourant la tige 20 et des moyens de verrouillage avec serrage axial de ces deux mâchoires l'une contre l'autre, les deux mâchoires pinçant entre elles, après verrouillage, la membrane M à la périphérie de son ouverture d'embrochement concernée. Un système similaire est déjà décrit en détail dans la demande
L'une de ces deux mâchoires est en l'espèce constituée par la pièce de raccord 60.One of these two jaws is in this case constituted by the connecting
L'autre mâchoire est constituée par la rondelle 70, illustrée plus en détail sur la
Une gorge annulaire 90 est ménagée sur l'extrémité avant 20a de la tige 20. Dans l'exemple illustré, la gorge annulaire 90 est l'espace délimité par deux collerettes parallèles, l'une avant 92, l'autre arrière 94, ménagées à la périphérie de la tige 20.An
La rondelle 70 possède une ouverture centrale d'emmanchement 72 bordée de deux languettes de clipsage 74 adaptées pour coopérer avec la collerette avant 92 de la tige 20.The
La collerette arrière 94 forme une butée axiale s'opposant à l'enfoncement de la rondelle 70 en direction de la charpente C. La collerette avant 92 forme une contrebutée s'opposant à l'extraction de la rondelle par l'extrémité avant de la tige.The
Au montage, la rondelle 70 est emmanchée sur la tige 20 après que la couche isolante a été embrochée sur la tige. La rondelle 70 est emmanchée à force pour franchir la collerette avant 92 de la tige, le bord de son ouverture centrale d'emmanchement 72 prenant appui contre la collerette arrière 94.On assembly, the
La membrane M est ensuite embrochée sur l'extrémité de la tige 20 et plaquée contre la rondelle 70 et la couche d'isolant.The membrane M is then plugged onto the end of the
La pièce de raccord 60 est à son tour emmanchée sur l'extrémité de la tige 20 et comprime la membrane M contre la rondelle 70. Lorsque la pièce de raccord 60 est dûment assemblée sur l'extrémité de la tige, la membrane M est pincée par la rondelle 70 et la pièce de raccord 60.The connecting
Ce pincement s'opère ici 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.This pinching takes place here 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.
La membrane M est alors maintenue derrière le profilé, à distance du parement de doublage. Un espace libre est ainsi ménagé entre le parement 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 membrane M is then held behind the profile, away from the cladding face. A free space is thus provided between the lining and the membrane and it is then possible to install in this space cabling, pipes or equipment without damaging the membrane.
Selon une variante non représentée, la garniture d'isolation peut être munie d'un pare-vapeur intégré, qui est percé lors de l'embrochement de la garniture. Afin de rétablir la fonction d'étanchéité à l'air, une membrane pré-percée, de dimensions latérales sensiblement inférieures à celles de la garniture, peut être fixée, notamment adhésivement, au pare-vapeur. La membrane est pré-percée et présente donc une ouverture d'embrochement permettant le passage de la tige sans déchirement de la membrane. La membrane est ensuite pincée à la périphérie de l'ouverture d'embrochement entre deux mâchoires. Avantageusement, l'une des mâchoires est constituée par la pièce de raccord 60, tandis que l'autre mâchoire est constituée par une rondelle entourant la tige et formée de préférence d'un seul tenant avec la tige, les dimensions latérales de la rondelle étant supérieures à celles de l'ouverture d'embrochement de la membrane.According to a variant not shown, the filling Insulation can be provided with a built-in vapor barrier, which is pierced when seaming the gasket. In order to restore the airtightness function, a pre-drilled membrane, with lateral dimensions substantially smaller than those of the lining, can be fixed, in particular adhesively, to the vapor barrier. The membrane is pre-drilled and thus has a skew opening for the passage of the rod without tearing of the membrane. The membrane is then pinched at the periphery of the skewer opening between two jaws. Advantageously, one of the jaws is constituted by the connecting
