Description

DOMAINE TECHNIQUETECHNICAL AREA

Le présent exposé concerne le domaine du doublage de structures, en particulier le doublage de plafonds ou d'intérieurs de toitures, à des fins d'isolation thermique et/acoustique ou esthétiques, au moyen de dispositifs d'entretoisement pour rapporter à distance de la structure à doubler, un parement de doublage.This presentation relates to the field of the lining of structures, in particular the lining of ceilings or roof interiors, for thermal and / acoustic or aesthetic insulation purposes, by means of bracing devices to bring back at a distance from the roof. structure to be doubled, a lining facing.

ARRIERE-PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

De manière connue, le doublage d'un plafond 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 dite 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 lining of a ceiling makes use of a covering system which usually comprises a thermal and / or acoustic insulation lining such as mineral wool, most often a so-called vapor barrier membrane which is added. against the insulation trim, and facing panels such as plasterboard or false ceiling panels which constitute the lining facing. To fix the facing plates, a metal frame made of profiles is attached at a distance from the structure to be lined, the insulation lining being interposed between the structure to be lined, 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 d'étanchéité.In order to facilitate the installation of the insulation lining and the fixing of the profiles, it is known to use spacer devices which serve both to remotely attach the profiles, and to hold the lining in place. insulation and waterproofing membrane.

La demande de brevet WO 2009/103911 , déposée par le demandeur, décrit un dispositif d'entretoisement de ce type comportant une tige munie à son extrémité proximale d'une platine de fixation percée de trous adaptés à recevoir des vis de fixation à la structure à doubler, et, à son extrémité distale, d'une pointe pour l'embrochement de la membrane d'étanchéité, autour de laquelle est rapportée une tête amovible de capotage, prenant en sandwich la membrane à la périphérie de son ouverture d'embrochement, la tête étant en outre dédiée à l'assemblage de la tige avec un profilé.The patent application WO 2009/103911 , filed by the applicant, describes a spacer device of this type comprising a rod provided at its proximal end with a fixing plate pierced with holes adapted to receive screws for fixing to the structure to be doubled, and, at its end distal, of a tip for the plugging-in of the sealing membrane, around which is attached a removable cowling head, sandwiching the membrane at the periphery of its plug-in opening, the head also being dedicated to assembly of the rod with a profile.

Un tel dispositif d'entretoisement présente de nombreux avantages. Il est facile et rapide à mettre en œuvre, permet de préserver l'étanchéité à la périphérie de l'ouverture d'embrochement de la membrane, et permet également de ménager un espace technique entre la membrane et les profilés. Avec un tel dispositif, cependant, il est nécessaire de régler très précisément la position de chaque tige avant de visser la platine de fixation sur la structure à doubler. Tout ajustement ultérieur de la position de la tige nécessite le dévissage et le revissage de la platine, qui sont des opérations longues et fastidieuses. Par ailleurs, la liberté de réglage de l'espacement entre la tige et la structure à doubler est forcément liée à la longueur de la tige.Such a spacer device has many advantages. It is easy and quick to use, makes it possible to preserve the seal at the periphery of the membrane plug-in opening, and also makes it possible to provide a technical space between the membrane and the profiles. With such a device, however, it is It is necessary to adjust the position of each rod very precisely before screwing the fixing plate on the structure to be doubled. Any subsequent adjustment of the position of the rod requires the unscrewing and screwing of the plate, which are long and tedious operations. Furthermore, the freedom to adjust the spacing between the rod and the structure to be doubled is necessarily linked to the length of the rod.

L'un des objectifs de la présente invention est de fournir un dispositif d'entretoisement plus facile à monter et plus polyvalent que celui de l'art antérieur, et pouvant néanmoins conserver les mêmes avantages.One of the objectives of the present invention is to provide a spacer device that is easier to assemble and more versatile than that of the prior art, and which can nevertheless retain the same advantages.

Dans le présent exposé, sauf précision contraire, la direction axiale correspond à la direction de l'axe longitudinal, et une direction radiale est une direction perpendiculaire à cet axe et coupant cet axe. De même, un plan axial est un plan contenant l'axe longitudinal de la tige et un plan radial est un plan perpendiculaire à cet axe. Sauf précision contraire, les adjectifs et adverbes axial, radial, axialement et radialement sont utilisés en référence aux directions axiale et radiale précitées.In the present description, unless otherwise specified, the axial direction corresponds to the direction of the longitudinal axis, and a radial direction is a direction perpendicular to this axis and intersecting this axis. Likewise, an axial plane is a plane containing the longitudinal axis of the rod and a radial plane is a plane perpendicular to this axis. Unless otherwise specified, the adjectives and adverbs axial, radial, axially and radially are used with reference to the aforementioned axial and radial directions.

Par ailleurs, les adjectifs proximal et distal, de même que les expressions amont et aval, sont utilisés en référence à la direction axiale, le deuxième système de fixation du dispositif étant disposé en aval du premier système de fixation.Furthermore, the adjectives proximal and distal, as well as the expressions upstream and downstream, are used with reference to the axial direction, the second fixing system of the device being arranged downstream of the first fixing system.

L'axe longitudinal de la tige correspond par exemple à son axe de symétrie.The longitudinal axis of the rod corresponds for example to its axis of symmetry.

Le dispositif d'entretoisement selon l'invention forme un embout de suspente adapté pour être fixé de façon réglable sur l'extrémité d'un axe fileté, en particulier un axe fileté préalablement fixé sur la structure à doubler.The spacer device according to the invention forms a hanger end piece adapted to be fixed in an adjustable manner on the end of a threaded pin, in particular a threaded pin previously fixed on the structure to be doubled.

Le positionnement exact du dispositif d'entretoisement peut être réglé de façon simple et précise après son montage sur l'axe fileté, et même après que l'ensemble des dispositifs d'entretoisement nécessaires pour le doublage a été monté sur la structure à doubler.The exact positioning of the bracing device can be easily and precisely adjusted after it has been mounted on the threaded axle, and even after all the bracing devices required for the liner have been mounted on the structure to be doubled.

Par ailleurs, le dispositif d'entretoisement selon l'invention peut coopérer avec des axes filetés de longueurs différentes. Ainsi, il est possible de rapporter un plafond plat sur une charpente inclinée en récupérant un niveau au moyen d'axes filetés de longueurs différentes coopérant chacun avec un dispositif d'entretoisement selon l'invention.Furthermore, the spacer device according to the invention can cooperate with threaded pins of different lengths. Thus, it is possible to attach a flat ceiling to an inclined frame by recovering a level by means of threaded pins of different lengths each cooperating with a spacer device according to the invention.

L'extrémité distale de la tige peut être configurée pour l'embrochement d'une membrane d'étanchéité du type pare-vapeur. Elle peut notamment former une extrémité d'embrochement pointue.The distal end of the rod can be configured for plugging in a vapor barrier type waterproofing membrane. It can in particular form a pointed plug-in end.

La tige peut aussi être adaptée pour recevoir à sa périphérie des moyens destinés à prendre en sandwich la membrane d'étanchéité en périphérie de son ouverture d'embrochement.The rod can also be adapted to receive at its periphery means intended to sandwich the waterproofing membrane at the periphery of its socket opening.

Selon l'invention, les moyens de fixation réglable du dispositif à un axe fileté comprennent un écrou adapté pour coopérer (par vissage) avec cet axe.According to the invention, the means for adjustable fixing of the device to a threaded axis comprise a nut adapted to cooperate (by screwing) with this axis.

L'axe de l'écrou est généralement parallèle à l'axe longitudinal de la tige, et de préférence confondu avec cet axe.The axis of the nut is generally parallel to the longitudinal axis of the rod, and preferably coincides with this axis.

Selon un exemple, l'écrou peut être formé par une pièce d'écrou distincte de la tige. La tige est alors munie d'un logement de réception adapté pour recevoir ladite pièce d'écrou et débouchant axialement pour le passage de l'axe fileté.According to one example, the nut may be formed by a separate nut part from the rod. The rod is then provided with a receiving housing adapted to receive said nut part and opening axially for the passage of the threaded shaft.

Typiquement, la tige est une pièce obtenue par moulage par injection d'un matériau polymère, notamment du polyamide.Typically, the rod is a part obtained by injection molding of a polymer material, in particular polyamide.

Elle peut éventuellement être renforcée en partie par une âme métallique.It may optionally be reinforced in part by a metal core.

La pièce d'écrou est par exemple réalisée dans un matériau métallique.The nut part is for example made of a metallic material.

Selon un exemple, la tige comporte au moins une ouverture de montage débouchant radialement, pour le montage de la pièce d'écrou dans le logement de réception.According to one example, the rod comprises at least one mounting opening opening out radially, for mounting the nut part in the receiving housing.

Selon un exemple, le dispositif comporte des moyens de blocage de la pièce d'écrou par rapport à la tige, en rotation autour de l'axe longitudinal. Par exemple, la pièce d'écrou et le logement de réception coopèrent par complémentarité de forme pour assurer ce blocage.According to one example, the device comprises means for locking the nut part with respect to the rod, in rotation about the longitudinal axis. For example, the nut part and the housing of reception cooperate by complementarity of form to ensure this blocking.

Les moyens de blocage pourraient également, comme variante, comporter un système de clavette.The locking means could also, as a variant, include a key system.

Selon un exemple, le dispositif d'entretoisement comprend des moyens pour le clipsage de la pièce d'écrou sur la tige.According to one example, the spacer device comprises means for clipping the nut part on the rod.

Par exemple, la tige comporte au moins une languette anti-retour élastiquement déformable (notamment disposée en périphérie de l'ouverture radiale de montage), adaptée pour se déformer lors de l'introduction de la pièce d'écrou à l'intérieur du logement de réception, et pour revenir après montage dans une position stable dans laquelle elle forme une butée s'opposant à la sortie de la pièce d'écrou hors du logement de réception.For example, the rod comprises at least one elastically deformable non-return tab (in particular disposed at the periphery of the radial mounting opening), adapted to deform during the introduction of the nut part inside the housing. reception, and to return after assembly to a stable position in which it forms a stop opposing the exit of the nut part from the reception housing.

Selon un autre exemple, la pièce d'écrou forme un clip adapté à venir pincer une paroi de la tigeAccording to another example, the nut piece forms a clip suitable for clamping a wall of the rod

Dans ce cas, elle comprend typiquement une partie principale portant une portion filetée configurée pour coopérer avec l'axe fileté et une partie d'attache reliée à la partie principale par une portion intermédiaire élastiquement déformable, la partie principale et la partie d'attache étant adaptées pour être écartées l'une de l'autre et montées de part et d'autre d'une paroi de la tige dans une position instable dans laquelle elles sont sollicitées élastiquement l'une vers l'autre, serrant entre elles ladite paroi. Dans cet exemple, une partie seulement de la pièce d'écrou est logée dans le logement de réception, après montage.In this case, it typically comprises a main part carrying a threaded portion configured to cooperate with the threaded axis and an attachment part connected to the main part by an elastically deformable intermediate portion, the main part and the attachment part being adapted to be separated from one another and mounted on either side of a wall of the rod in an unstable position in which they are resiliently urged towards each other, clamping said wall together. In this example, only part of the nut part is housed in the receiving housing, after assembly.

Selon un exemple, la portion intermédiaire comprend au moins une lame ressort.According to one example, the intermediate portion comprises at least one leaf spring.

La pièce d'écrou peut notamment venir se clipser autour d'une paroi de la tige s'étendant dans un plan radial, notamment la paroi d'extrémité proximale de la tige.The nut piece can in particular come to be clipped around a wall of the rod extending in a radial plane, in particular the proximal end wall of the rod.

Dans ce cas, pour améliorer la fixation de la pièce d'écrou, la partie d'attache de la pièce d'écrou peut également être munie d'une ouverture, notamment un trou généralement non taraudé, adaptée pour recevoir l'axe fileté.In this case, to improve the fixing of the nut part, the attachment part of the nut part can also be provided with an opening, in particular a generally unthreaded hole, adapted to receive the threaded axis.

Lorsque les moyens de fixation réglable sont formés par un écrou, la position du dispositif par rapport à l'axe fileté, dans la direction axiale, peut être modifiée facilement par simple vissage/dévissage.When the adjustable fixing means are formed by a nut, the position of the device with respect to the threaded axis, in the axial direction, can be easily changed by simple screwing / unscrewing.

Selon l'invention, le dispositif comporte un espace libre de réglage adapté pour recevoir l'axe fileté, en aval de l'écrou.According to the invention, the device comprises a free adjustment space suitable for receiving the threaded axis, downstream of the nut.

On comprend que l'espace libre de réglage est alors situé, le long de l'axe longitudinal, entre l'écrou et l'extrémité distale de la tige. On définit la longueur de réglage du dispositif comme la longueur, mesurée dans la direction axiale, sur laquelle l'axe fileté peut être déplacé en aval de l'écrou.It will be understood that the free adjustment space is then situated, along the longitudinal axis, between the nut and the distal end of the rod. The adjustment length of the device is defined as the length, measured in the axial direction, over which the threaded axis can be moved downstream of the nut.

Il est souhaitable, pour assurer une accroche et une bonne tenue à la traction que l'axe fileté coopère avec l'écrou sur une longueur suffisante de filetage, et de préférence sur toute la longueur de l'écrou.In order to ensure grip and good tensile strength, it is desirable for the threaded pin to cooperate with the nut over a sufficient length of thread, and preferably over the entire length of the nut.

Pour permettre à l'utilisateur de vérifier que l'axe fileté a bien traversé l'écrou de part en part, la tige comporte au moins une ouverture radiale de visualisation de l'espace libre de réglage.To allow the user to check that the threaded pin has passed right through the nut right through, the rod has at least one radial opening for viewing the free adjustment space.

De façon avantageuse, l'ouverture radiale de visualisation est située en regard de l'extrémité aval de l'écrou. Elle s'étend par exemple sur une longueur axiale d'au moins deux millimètres à partir de l'extrémité aval de l'écrou. Elle peut s'étendre sous une partie ou sur toute la longueur de l'espace de réglage.Advantageously, the radial viewing opening is located opposite the downstream end of the nut. It extends for example over an axial length of at least two millimeters from the downstream end of the nut. It may extend under part or over the entire length of the adjustment space.

Pour permettre à l'utilisateur de vérifier facilement le montage quelle que soit sa position, le dispositif peut, selon une disposition, être configuré de sorte que l'espace de réglage soit visible depuis deux côtés radialement opposés de la tige. Une ouverture de visualisation traverse avantageusement la tige de part en part, dans une direction radiale.To allow the user to easily check the fitment regardless of its position, the device may, in one arrangement, be configured so that the adjustment space is visible from two radially opposite sides of the rod. A viewing opening advantageously passes right through the rod in a radial direction.

Selon un exemple, la tige comporte une cavité formant réservoir adaptée pour recevoir l'axe fileté en aval de l'écrou.According to one example, the rod comprises a cavity forming a reservoir adapted to receive the threaded axis downstream of the nut.

Typiquement, le réservoir présente, au moins sur une portion de sa longueur, une section circulaire sensiblement complémentaire de celle de l'axe fileté. La coopération entre l'axe fileté et les parois internes du réservoir améliore la rigidité de l'ensemble.Typically, the reservoir has, at least over a portion of its length, a circular section substantially complementary to that of the threaded axis. The cooperation between the threaded axis and the internal walls of the tank improves the rigidity of the assembly.

DESCRIPTION DETAILLEE D'EXEMPLES DE REALISATIONDETAILED DESCRIPTION OF EXAMPLES OF IMPLEMENTATION

Les figure 1 à 5 illustrent un dispositif d'entretoisement 100 selon un premier mode de réalisation de l'invention, destiné à être utilisé dans le cadre du doublage d'une structure S notamment d'un plafond, par exemple un plafond plat en bois, comme représenté sur la figure 8 et décrit plus en détail dans la suite.The figure 1 to 5 illustrate a spacer device 100 according to a first embodiment of the invention, intended to be used in the context of the lining of a structure S in particular of a ceiling, for example a flat wooden ceiling, as shown in FIG. figure 8 and described in more detail below.

Le doublage consiste à installer de manière connue des dispositifs d'entretoisement 100, une garniture d'isolation G, une membrane d'étanchéité M, et des profilés de fixation F pour plaques de parement P, les profilés F étant portés à l'extrémité des dispositifs d'entretoisement 100.The lining consists in installing in a known manner spacer devices 100, an insulation lining G, a waterproofing membrane M, and fixing profiles F for facing plates P, the profiles F being carried at the end bracing devices 100.

Selon l'invention, le dispositif d'entretoisement 100 est destiné à être fixé à l'extrémité d'un axe fileté A, fixé lui-même sur la structure à doubler S par tout moyen adapté. L'axe fileté peut par exemple être engagé dans un tube taraudé noyé dans le matériau de la structure (par exemple si la structure est en béton), ou dans un tube taraudé lui-même fixé à un support solidaire de la surface de la structure.According to the invention, the spacer device 100 is intended to be fixed to the end of a threaded pin A, itself fixed to the structure to be doubled S by any suitable means. The threaded axis can for example be engaged in a threaded tube embedded in the material of the structure (for example if the structure is concrete), or in a threaded tube itself fixed to a support integral with the surface of the structure .

Le dispositif d'entretoisement 100 comporte une tige 10 s'étendant selon un axe longitudinal X (dans la suite, on appelle aussi direction axiale X la direction de cet axe).The spacer device 100 comprises a rod 10 extending along a longitudinal axis X (hereinafter, the direction of this axis is also called the axial direction X).

La tige 10 est par exemple une pièce moulée par injection, réalisée en polyamide.The rod 10 is for example an injection-molded part, made of polyamide.

Elle a par exemple une longueur L comprise entre 7 et 10 cm.It has for example a length L of between 7 and 10 cm.

L'extrémité distale 10a de la tige (son extrémité la plus éloignée de la structure à doubler en position montée) est configurée pour permettre le percement de la membrane d'étanchéité M, et présente pour cela une terminaison en pointe 70.The distal end 10a of the rod (its end furthest from the structure to be doubled in the mounted position) is configured to allow the piercing of the sealing membrane M, and for this has a pointed termination 70.

Comme illustré plus particulièrement sur les figures 2 et 3, le dispositif d'entretoisement comporte en outre, à l'extrémité distale de la tige, des moyens destinés à prendre en sandwich la membrane d'étanchéité M.As illustrated more particularly on figures 2 and 3 , the spacer device further comprises, at the distal end of the rod, means intended to sandwich the sealing membrane M.

Ces moyens comprennent par exemple deux mâchoires annulaires 82, 84 entourant la tige 10 et des moyens de verrouillage avec serrage axial de ces deux mâchoires l'une contre l'autre, les deux mâchoires étant adaptées pour pincer entre elles, après verrouillage, la membrane M à la périphérie de son ouverture d'embrochement concernée. Les mâchoires 82, 84 sont ici agencées pour présenter, après verrouillage, une zone de contact mutuel continue et refermée sur elle-même.These means comprise for example two annular jaws 82, 84 surrounding the rod 10 and locking means with axial clamping of these two jaws against each other, the two jaws being adapted to clamp between them, after locking, the membrane. M at the periphery of its relevant branching opening. The jaws 82, 84 are here arranged to present, after locking, a zone of continuous mutual contact which is closed on itself.

Les deux mâchoires forment ensemble une tête de capotage 80 dont une partie est dédiée, comme il sera décrit ci-après, à l'assemblage de la tige 10 avec un profilé F.The two jaws together form a cowling head 80, a part of which is dedicated, as will be described below, to the assembly of the rod 10 with a section F.

Un tel système est décrit plus en détail dans la demande WO 2009/103911 .Such a system is described in more detail in the application. WO 2009/103911 .

Selon l'exemple (non limitatif) illustré sur les figures 2 et 3, les deux mâchoires sont des pièces distinctes de la tige.According to the example (non-limiting) illustrated on the figures 2 and 3 , the two jaws are separate parts of the rod.

L'une des mâchoires est ici constituée par une rondelle 82 ayant une ouverture centrale 83 pour son montage sur la tige 10. Cette rondelle 82 est de forme conique et est apte à se déformer.One of the jaws is here constituted by a washer 82 having a central opening 83 for its mounting on the rod 10. This washer 82 is of conical shape and is able to deform.

L'autre mâchoire est constituée par un chapeau 84 clippé sur l'extrémité distale 10a de la tige 10.The other jaw consists of a cap 84 clipped onto the distal end 10a of the rod 10.

Pour coopérer avec ces mâchoires, la tige 10 comporte ici, à son extrémité distale 10a, en amont de sa pointe 70, une gorge de verrouillage 60 dont le flanc amont forme une butée axiale 62 destinée à s'opposer à l'enfoncement de la rondelle 82 en direction de la structure à doubler et dont le flanc aval forme une contre-butée axiale 64 avec laquelle le chapeau 84 est engageable.To cooperate with these jaws, the rod 10 comprises here, at its distal end 10a, upstream of its tip 70, a locking groove 60, the upstream side of which forms an axial stop 62 intended to oppose the depression of the washer 82 in the direction of the structure to be doubled and whose downstream side forms an axial counter-stop 64 with which the cap 84 can be engaged.

Lorsque la rondelle 82 est engagée sur la tige et que le chapeau 84 est clippé, la rondelle 82 est déformée contre le chapeau 84, et la membrane M se retrouve pincée ou « prise en sandwich » entre les deux mâchoires, qui obturent alors son ouverture d'embrochement.When the washer 82 is engaged on the rod and the cap 84 is clipped, the washer 82 is deformed against the cap 84, and the membrane M is found pinched or “sandwiched” between the two jaws, which then close its opening. plug-in.

Outre sa fonction de pincement ou "prise en sandwich" de la membrane M, le chapeau 84 forme également une pièce de raccord permettant l'assemblage au dispositif d'un profilé F (grâce à une rainure 85 formée à sa périphérie et adaptée à recevoir les extrémités des bras recourbés du profilé).In addition to its function of pinching or "sandwiching" the membrane M, the cap 84 also forms a connecting piece allowing the assembly to the device of a section F (thanks to a groove 85 formed at its periphery and adapted to receive the ends of the curved arms of the profile).

L'exemple décrit ci-dessus n'est toutefois pas limitatif.The example described above is not, however, limiting.

Selon une autre variante, une première mâchoire est formée par une collerette en saillie à la périphérie de la tige, et d'un seul tenant avec celle-ci.According to another variant, a first jaw is formed by a collar projecting from the periphery of the rod, and in one piece therewith.

Selon encore une autre variante, l'une parmi la première et la seconde mâchoire comporte un joint compressible, adapté à venir se comprimer contre la membrane une fois les deux mâchoires serrées l'une contre l'autre.According to yet another variant, one of the first and the second jaw comprises a compressible seal, adapted to come to be compressed against the membrane once the two jaws are clamped against each other.

Le montage de la membrane M et son verrouillage par la tête de capotage 80 seront décrits plus en détail dans la suite de la description.The mounting of the membrane M and its locking by the cowling head 80 will be described in more detail in the remainder of the description.

A l'extrémité proximale 10b de la tige (son extrémité la plus proche de la structure à doubler S en position montée, opposée à l'extrémité distale 10a), le dispositif 100 comporte un système pour sa fixation à la structure S et plus particulièrement, des moyens pour sa fixation réglable à l'axe fileté A solidaire de cette structure S.At the proximal end 10b of the rod (its end closest to the structure to be doubled S in the mounted position, opposite the distal end 10a), the device 100 comprises a system for its attachment to the structure S and more particularly , means for its adjustable attachment to the threaded axis A integral with this structure S.

Ces moyens comprennent ici une pièce d'écrou 20, distincte de la tige 10, adaptée pour être montée sur la tige 10 de façon à être bloquée par rapport à celle-ci en rotation autour de l'axe longitudinal X.These means here comprise a nut part 20, separate from the rod 10, adapted to be mounted on the rod 10 so as to be blocked with respect to the latter in rotation about the longitudinal axis X.

La pièce d'écrou est représentée plus en détail sur la figure 4.The nut part is shown in more detail on the figure 4 .

Dans l'exemple, elle se présente sous la forme d'un bloc métallique traversé de part en part par un trou taraudé 22 adapté pour coopérer par vissage avec l'axe fileté A, et dont l'axe X1 s'étend ici orthogonalement à deux faces principales 20a, 20b de la pièce.In the example, it is in the form of a metal block crossed right through by a threaded hole 22 adapted to cooperate by screwing with the threaded axis A, and whose axis X1 here extends orthogonally to two main faces 20a, 20b of the part.

Comme illustré sur la figure 3, la pièce d'écrou comporte en outre quatre faces latérales 20c, 20d, 20e, 20f parallèles deux à deux, et orthogonales aux faces principales 20a, 20b.As shown on the figure 3 , the nut piece further comprises four side faces 20c, 20d, 20e, 20f parallel two by two, and orthogonal to the main faces 20a, 20b.

Dans l'exemple, la pièce est centrée sur l'axe X1 et présente, dans un plan orthogonal à cet axe, une section carrée.In the example, the part is centered on the X1 axis and has, in a plane orthogonal to this axis, a square section.

Pour des raisons décrites dans la suite de la présente description, la pièce d'écrou 20 présente avantageusement au moins un coin tronqué. Par coin, on entend ici le sommet formé par une face latérale 20c, 20d, 20e, 20f et une face principale 20a, 20b de la pièce et s'étendant sur toute une largeur commune des dites faces. Le coin est généralement tronqué sur toute cette largeur. Un coin tronqué peut notamment être chanfreiné ou arrondi.For reasons described in the remainder of the present description, the nut part 20 advantageously has at least one truncated wedge. By corner is meant here the apex formed by a side face 20c, 20d, 20e, 20f and a main face 20a, 20b of the part and extending over a whole common width of said faces. The wedge is usually truncated across this width. A truncated corner can in particular be chamfered or rounded.

Dans l'exemple représenté, plus particulièrement, la pièce d'écrou 20 est tronquée sur tout le pourtour de sa face principale 20b (chanfrein 24 illustré sur la figure 3).In the example shown, more particularly, the nut part 20 is truncated over the entire periphery of its main face 20b (chamfer 24 shown on figure 3 ).

La pièce d'écrou 20 est montée dans un logement de réception formé sur la tige 10 et configuré pour son maintien en position dans les directions axiale et radiale, après montage, comme il sera décrit dans la suite.The nut part 20 is mounted in a receiving housing formed on the rod 10 and configured to hold it in position in the axial and radial directions, after assembly, as will be described below.

Dans l'exemple, le logement de réception 12 est formé par une cavité à section en T traversant la tige de part en part dans une direction radiale Y1.In the example, the receiving housing 12 is formed by a T-section cavity passing right through the rod in a radial direction Y1.

La pièce d'écrou est destinée à être insérée dans la partie principale 13 de la cavité, qui correspond à la partie haute du T. Elle est délimitée dans la direction axiale X par une surface supérieure 30 et ici deux surfaces inférieures coplanaires 32, 32' et dans une direction radiale Y2 orthogonale à Y1, par deux surfaces sensiblement parallèles 34, 36. Sa section dans un plan orthogonal à Y1 est complémentaire de celle de la pièce d'écrou 20.The nut piece is intended to be inserted into the main part 13 of the cavity, which corresponds to the upper part of the T. It is delimited in the axial direction X by an upper surface 30 and here two coplanar lower surfaces 32, 32 'and in a radial direction Y2 orthogonal to Y1, by two substantially parallel surfaces 34, 36. Its section in a plane orthogonal to Y1 is complementary to that of the nut part 20.

Ainsi, une fois montée dans le logement de réception 12, la pièce d'écrou 20 est bloquée en translation dans la direction axiale par les faces supérieure et inférieures 30, 32, 32', et dans la direction radiale Y2, par les faces latérales 34, 36.Thus, once mounted in the receiving housing 12, the nut piece 20 is blocked in translation in the axial direction by the upper and lower faces 30, 32, 32 ', and in the radial direction Y2, by the side faces 34, 36.

La coopération entre les faces du logement de réception 12 et les faces latérales 20c, 20d, 20e, 20f de la pièce d'écrou 20 bloque en outre toute rotation relative entre les deux pièces autour de l'axe longitudinal X.The cooperation between the faces of the receiving housing 12 and the side faces 20c, 20d, 20e, 20f of the nut piece 20 furthermore blocks any relative rotation between the two pieces around the longitudinal axis X.

La tige 10 est également pourvue de moyens de blocage en translation de la pièce d'écrou à l'intérieur du logement de réception 12, dans la direction radiale Y1.The rod 10 is also provided with means for locking the nut part in translation inside the receiving housing 12, in the radial direction Y1.

A une extrémité, la cavité 12 est obturée partiellement par une portion de paroi 16.At one end, the cavity 12 is partially closed by a portion of the wall 16.

L'autre extrémité de la cavité 12 forme une ouverture de montage par laquelle doit être insérée la pièce d'écrou 20 lors du montage.The other end of the cavity 12 forms a mounting opening through which the nut piece 20 must be inserted during mounting.

En bordure de cette ouverture, la tige 10 est pourvue de moyens de clipsage de la pièce d'écrou à l'intérieur du logement de réception 12, ici au moins une languette anti-retour élastiquement déformable 18.At the edge of this opening, the rod 10 is provided with means for clipping the nut part inside the housing of reception 12, here at least one elastically deformable non-return tab 18.

La languette 18 est adaptée pour prendre lors du montage une position déformée dans laquelle elle laisse passer la pièce d'écrou 20 ;The tongue 18 is adapted to take during assembly a deformed position in which it allows the nut part 20 to pass;

Dans l'exemple, la languette 18 glisse sur le coin tronqué de la pièce d'écrou 20 au moment de son insertion dans le logement de réception 12, et est ainsi rabattue progressivement vers la face supérieure 30.In the example, the tongue 18 slides over the truncated corner of the nut piece 20 when it is inserted into the receiving housing 12, and is thus gradually folded down towards the upper face 30.

Après montage, la languette 18 retrouve sa position initiale, stable, dans laquelle elle forme une butée s'opposant à la sortie de la pièce d'écrou 20 hors du logement de réception 12.After assembly, the tongue 18 returns to its initial, stable position, in which it forms a stop opposing the exit of the nut piece 20 from the receiving housing 12.

L'exemple illustré n'est cependant pas limitatif. Le logement de réception peut être formé par une cavité dont la section présente toute autre forme adaptée permettant l'insertion de la pièce d'écrou, la tige étant pourvue de moyens pour le blocage en translation de ladite pièce à l'intérieur dudit logement dans les directions axiale et radiale.The example illustrated is not, however, limiting. The receiving housing may be formed by a cavity, the section of which has any other suitable shape allowing the insertion of the nut piece, the rod being provided with means for locking said piece in translation inside said housing in the axial and radial directions.

Bien évidemment, comme illustré sur la figure 2, le logement de réception 12 est également ouvert dans la direction axiale X pour permettre l'introduction de l'axe fileté A et son vissage sur la pièce d'écrou 20.Obviously, as illustrated on figure 2 , the receiving housing 12 is also open in the axial direction X to allow the introduction of the threaded axis A and its screwing on the nut part 20.

Dans l'exemple, la paroi d'extrémité proximale 31 de la tige 10 est ainsi percée d'un orifice 33 à section circulaire centré sur l'axe longitudinal X de la tige 10.In the example, the proximal end wall 31 of the rod 10 is thus pierced with an orifice 33 of circular section centered on the longitudinal axis X of the rod 10.

Comme illustré sur la figure 2, un espace libre de réglage 40 est conservé en aval de la pièce d'écrou 20.As shown on the figure 2 , a free adjustment space 40 is kept downstream of the nut part 20.

Cet espace libre 40 est adapté pour recevoir l'extrémité de l'axe fileté A.This free space 40 is adapted to receive the end of the threaded shaft A.

La longueur L1 de l'espace libre de réglage (voir figure 2) est donc la longueur de réglage du dispositif. Elle est comprise typiquement entre 20mm et 60mm, de préférence entre 35mm et 45mm.The length L1 of the free adjustment space (see figure 2 ) is therefore the adjustment length of the device. It is typically between 20mm and 60mm, preferably between 35mm and 45mm.

Une partie de cet espace libre 40, située directement en aval de la pièce d'écrou 20, peut avantageusement être visualisée par une ouverture radiale de la tige 10.Part of this free space 40, located directly downstream of the nut part 20, can advantageously be viewed by a radial opening of the rod 10.

Dans l'exemple, cette ouverture radiale correspond à la partie secondaire 14 de la cavité à section en T traversant la tige de part en part dans une direction radiale Y1 (correspondant au pied du T).In the example, this radial opening corresponds to the secondary part 14 of the T-section cavity passing right through the rod in a radial direction Y1 (corresponding to the foot of the T).

L'ouverture traversant la tige 10 sur toute son épaisseur, l'utilisateur est en mesure de visualiser le dépassement de l'axe fileté A au-delà de l'écrou indifféremment d'un côté ou de l'autre du dispositif.The opening passing through the rod 10 over its entire thickness, the user is able to visualize the protrusion of the threaded axis A beyond the nut either side of the device.

L'espace libre de réglage 40 est en outre formé par une partie creuse 42 de la tige 10, formant réservoir pour l'extrémité de l'axe fileté A.The free adjustment space 40 is further formed by a hollow portion 42 of the rod 10, forming a reservoir for the end of the threaded shaft A.

La partie creuse s'étend donc en direction axiale.The hollow part therefore extends in the axial direction.

Elle présente, au moins sur une partie de sa longueur, une section interne circulaire correspondant à celle de l'axe fileté A. Elle peut aussi, comme illustré sur la figure 2, comporter une portion supérieure évasée, formant guide pour l'axe fileté.It has, at least over part of its length, a circular internal section corresponding to that of the threaded axis A. It can also, as illustrated on figure 2 , have a flared upper portion, forming a guide for the threaded shaft.

La figure 8 illustre un doublage de plafond réalisé à l'aide de dispositifs d'entretoisement selon l'invention.The figure 8 illustrates a ceiling lining produced using bracing devices according to the invention.

Un tel doublage est réalisé de la façon suivante :
Les axes filetés A sont préalablement fixés à la structure à doubler S, ici, par exemple par vissage dans des supports taraudés solidaires des solives.Such dubbing is carried out as follows:
The threaded pins A are previously fixed to the structure to be doubled S, here, for example by screwing in threaded supports integral with the joists.

Un contre-écrou 50 est vissé sur chaque axe fileté A.A lock nut 50 is screwed onto each threaded axis A.

Une tige 10, préassemblée avec une pièce d'écrou 20, est ensuite montée sur chaque axe fileté A, par vissage.A rod 10, pre-assembled with a piece of nut 20, is then mounted on each threaded shaft A, by screwing.

On admet généralement qu'une accroche et une tenue à la traction suffisantes sont obtenues lorsque l'axe fileté A dépasse de l'écrou d'environ 2mm.It is generally accepted that sufficient grip and tensile strength are obtained when the threaded axis A protrudes from the nut by about 2mm.

L'opérateur contrôle, par l'ouverture de visualisation 14, que l'extrémité de l'axe fileté A dépasse bien en aval de la pièce d'écrou 20.The operator checks, through the viewing opening 14, that the end of the threaded shaft A protrudes well downstream from the nut part 20.

Le positionnement exact de chaque tige est réglé par vissage.The exact positioning of each rod is adjusted by screwing.

Une fois la position de la tige 10 définie, le contre-écrou 50 est amené en butée contre la paroi d'extrémité proximale 31 de la tige 10.Once the position of the rod 10 is defined, the lock nut 50 is brought into abutment against the proximal end wall 31 of the rod 10.

Une garniture d'isolation thermique et/ou acoustique est insérée entre le plafond à doubler et la cloison de doublage. Cette garniture comporte au moins une couche épaisse de matériau isolant fibreux tel que de la laine minérale, de la laine d'origine animale ou de la laine végétale. Elle est constituée d'une succession de panneaux ou de lés de feutre isolants.A thermal and / or acoustic insulation trim is inserted between the ceiling to be lined and the lining partition. This lining comprises at least one thick layer of fibrous insulating material such as mineral wool, wool of animal origin or vegetable wool. It is made up of a succession of insulating felt panels or strips.

Les lés de matériau isolant sont par exemple coincés entre les solives du plafond et/ou embrochés sur la tige ou autre.The strips of insulating material are for example wedged between the joists of the ceiling and / or plugged into the rod or the like.

La rondelle 82 est ensuite emmanchée sur la tige, le bord de son ouverture centrale 83 prenant appui contre le flanc arrière 62 de la gorge de verrouillage 60.The washer 82 is then fitted onto the rod, the edge of its central opening 83 resting against the rear side 62 of the locking groove 60.

La membrane M est ensuite embrochée sur l'extrémité distale 10a de la tige 10 et plaquée contre la rondelle 82.The membrane M is then plugged into the distal end 10a of the rod 10 and pressed against the washer 82.

Le chapeau 84 est à son tour emmanché à force sur l'extrémité de la tige 10 et comprime la membrane M contre la rondelle 82. La rondelle 82, qui est initialement conique et dont la périphérie est repoussée par la face arrière plane du chapeau 84, se déforme pour s'aplatir et pincer, avec le chapeau 84, la membrane M autour de son ouverture d'embrochement.The cap 84 is in turn force-fitted onto the end of the rod 10 and compresses the membrane M against the washer 82. The washer 82, which is initially conical and the periphery of which is pushed back by the flat rear face of the cap 84 , is deformed to flatten and pinch, with the cap 84, the membrane M around its socket opening.

Les profilés F sont ensuite encliquetés dans les gorges 85 des chapeaux 84, puis les plaques de parement P sont vissées sur lesdits profilés.The profiles F are then snapped into the grooves 85 of the caps 84, then the facing plates P are screwed onto said profiles.

La membrane M est finalement maintenue par le chapeau 84 et la rondelle 82 derrière les profilés F, à distance de la cloison de doublage 30. Un espace technique 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 membrane M is finally held by the cap 84 and the washer 82 behind the profiles F, at a distance from the lining partition 30. A technical space is thus provided between the lining partition and the membrane and it is then possible to install cables, pipes or equipment in this space without damaging the membrane.

Les figures 6 et 7 illustrent un dispositif d'entretoisement 200 selon un deuxième mode de réalisation de l'invention. Les éléments identiques ou similaires à ceux décrits en liaison avec le premier mode de réalisation sont désignés par les mêmes références numériques que sur les figures 1 et 2, incrémentées de 100, et ne sont pas décrits une nouvelle fois.The figures 6 and 7 illustrate a spacer device 200 according to a second embodiment of the invention. The elements identical or similar to those described in connection with the first embodiment are designated by the same reference numerals as on the figures 1 and 2 , incremented by 100, and are not described again.

Comme dans le premier mode de réalisation, la tige comporte un logement de réception 112 pour une pièce d'écrou 120, sous la forme d'une cavité traversante s'étendant radialement.As in the first embodiment, the rod has a receiving housing 112 for a nut piece 120, in the form of a through cavity extending radially.

Dans ce mode de réalisation, la pièce d'écrou se présente sous la forme d'une pince, clipsable sur une paroi de la tige.In this embodiment, the nut piece is in the form of a clamp, which can be clipped onto a wall of the rod.

Plus particulièrement, la pièce d'écrou est clipsée sur la paroi d'extrémité proximale 131 de la tige 110, laquelle s'étend radialement et présente une ouverture de passage pour l'axe fileté jusque dans le logement de réception.More particularly, the nut piece is clipped onto the proximal end wall 131 of the rod 110, which extends radially and has a passage opening for the threaded axis into the receiving housing.

Comme illustré plus en détail sur la figure 7, la pièce d'écrou comprend

  • une partie principale 190 destinée à être insérée dans le logement de réception 112 et portant une ouverture taraudée 192 d'axe X2, configurée pour coopérer avec l'axe fileté, et
  • une partie d'attache 194, munie d'un trou (non représenté) adapté pour venir en regard de l'ouverture de la paroi proximale 131 pour le passage de l'axe fileté A.
As illustrated in more detail on figure 7 , the nut part includes
  • a main part 190 intended to be inserted into the receiving housing 112 and carrying a threaded opening 192 of axis X2, configured to cooperate with the threaded axis, and
  • an attachment part 194, provided with a hole (not shown) adapted to come opposite the opening of the proximal wall 131 for the passage of the threaded axis A.

La partie principale 190 et la partie d'attache 194 sont globalement superposées dans la direction de l'axe X2.The main part 190 and the attachment part 194 are generally superimposed in the direction of the axis X2.

Elles sont par ailleurs reliées par des moyens élastiquement déformable, formant ressort.They are also connected by elastically deformable means, forming a spring.

Pour leur montage sur la paroi, la partie principale 190 et la partie d'attache 194 sont écartées l'une de l'autre à l'encontre de la force de rappel de ces moyens ressort. La pièce d'écrou 120, une fois montée, est ainsi dans une position instable dans laquelle les parties principale 190 et d'attache 194 sont sollicitées élastiquement l'une vers l'autre, serrant entre elles ladite paroi 131.For their mounting on the wall, the main part 190 and the attachment part 194 are spaced from each other against the restoring force of these spring means. The nut part 120, once mounted, is thus in an unstable position in which the main 190 and attachment 194 parts are resiliently biased towards each other, clamping said wall 131 together.

Dans l'exemple, les moyens ressort comprennent deux lames ressort 196, 198, s'étendant dans une direction Z dite direction principale de la pièce.In the example, the spring means comprise two leaf spring 196, 198, extending in a direction Z called the main direction of the part.

Dans l'exemple, la partie d'attache 194 est fixée aux premières extrémités 196a, 198a des deux lames ressort 196, 198 et la partie de fixation 190 est fixée aux deuxièmes extrémités 196b, 198b des deux lames ressort.In the example, the attachment part 194 is fixed to the first ends 196a, 198a of the two leaf springs 196, 198 and the fixing part 190 is fixed to the second ends 196b, 198b of the two leaf springs.

Plus particulièrement, les deux lames ressort 196, 198 sont reliées entre elles au niveau de leur deuxièmes extrémités 196b, 198b par une barre transversale 199, et la partie principale 194 est formée par un retour s'étendant depuis ladite barre transversale 199, entre les deux lames ressort 196, 198, et en direction des premières extrémités 196a, 198a.More particularly, the two leaf springs 196, 198 are interconnected at their second ends 196b, 198b by a transverse bar 199, and the main part 194 is formed by a return extending from said transverse bar 199, between the two leaves spring 196, 198, and in the direction of the first ends 196a, 198a.
