Description

La présente invention concerne un dispositif d'entretoisement pour le maintien à écartement réglable d'un rail, support d'élément de parement, tel que plaque de plâtre, par rapport à une surface de référence, telle que mur ou plafond, à revêtir dudit parement.The present invention relates to a bracing device for maintaining an adjustable spacing of a rail, facing element support, such as plasterboard, with respect to a reference surface, such as a wall or a ceiling, to be coated with said facing.

Elle concerne plus particulièrement un dispositif d'entretoisement comprenant un support du genre plot, sur lequel le rail est apte à s'encliqueter, et une base de fixation du support à la surface de référence, ladite base comprenant un corps tubulaire muni à l'une de ses extrémités, dite extrémité d'appui, d'une surface d'appui sur la surface de référence, ladite surface d'appui s'étendant perpendiculairement à l'axe longitudinal dudit corps, ledit support du genre plot étant muni d'un passage axial traversant pour pouvoir être enfilé et monté sur le corps tubulaire de la base, à écartement réglable par rapport à la surface d'appui dudit corps, le dispositif comportant en outre une vis apte à être introduite axialement dans le corps de la base jusqu'à faire saillie de la surface d'appui pour solidariser par vissage la base à la surface de référence.It relates more particularly to a bracing device comprising a support of the kind stud, on which the rail is adapted to snap, and a base for fixing the support to the reference surface, said base comprising a tubular body provided with the one of its ends, said support end, of a bearing surface on the reference surface, said bearing surface extending perpendicular to the longitudinal axis of said body, said support of the genus pad being provided with an axial through passage to be threaded and mounted on the tubular body of the base, adjustable spacing relative to the bearing surface of said body, the device further comprising a screw adapted to be introduced axially into the body of the base until protruding from the bearing surface for fastening by screwing the base to the reference surface.

On connaît également, à travers le brevet allemand DE-3045474 , un dispositif d'entretoisement du type précité. Dans un tel dispositif d'entretoisement, soit on considère que le support du genre plot intègre le siège de la vis de fixation de la base de fixation à la surface de référence ou, en d'autres termes, que les parties, représentées en 5, 6, 7, 8, 9 et 14, sont ré alisées d'une seule pièce. Dans ce cas, lors d'un déplacement axial du support le long du corps tubulaire de la base, le siège d'appui de la vis intégré au support se déplace également de sorte qu'il est nécessaire de déplacer la vis pour la ramener en appui contre son siège pour assurer une étanchéité entre vis et siège de la vis. Ainsi, à chaque nouveau réglage du support pour modifier l'écartement du rail par rapport à la surface de référence, il faut également visser ou dévisser la vis. On pourrait également considérer que le siège de la vis est solidaire du corps tubulaire de la base de fixation. Dans ce cas, le siège tel qu'il est réalisé forme une butée de retenue du support sur le corps de la base et empêche une extraction du support par cette même extrémité du corps de la base. Il est alors nécessaire que l'autre extrémité du corps de la base soit réalisée démontable, ce qui rend plus complexe la garantie d'une étanchéité à ce niveau.We also know, through the German patent DE-3045474 , a bracing device of the aforementioned type. In such a bracing device, it is considered that the support of the genus stud integrates the seat of the fastening screw of the fastening base to the reference surface or, in other words, that the parts, represented in FIG. , 6, 7, 8, 9 and 14 are made in one piece. In this case, during an axial displacement of the support along the tubular body of the base, the support seat of the screw integrated in the support also moves so that it is necessary to move the screw to bring it back into position. support against its seat to ensure a seal between screw and seat of the screw. Thus, with each new setting of the support to change the spacing of the rail relative to the reference surface, it is also necessary to screw or unscrew the screw. We could also consider that the seat of the screw is integral with the body tubular of the fixation base. In this case, the seat as it is formed forms a support retaining stop on the body of the base and prevents extraction of the support by the same end of the body of the base. It is then necessary that the other end of the body of the base is made removable, which makes more complex the guarantee of a seal at this level.

Un autre exemple d'un dispositif d'entretoisement est fourni dans le brevet européen EP-0.236.224 . Dans un tel dispositif d'entretoisement, la base est formée d'un croisillon au droit de la zone centrale duquel est prévu un élément d'entretoisement constitué par un tube creux. La fixation de la base à la surface de référence s'opère par vissage. A cet effet, chaque branche du croisillon comporte un trou traversant pour sa fixation à la surface de référence. Or, de plus en plus souvent, les surfaces de référence à équiper d'un parement sont étanchéifiées à l'aide d'un film pare-vapeur. La fixation d'un croisillon, tel que mentionné ci-dessus, génère donc une multiplication des perçages nuisant à l'étanchéité devant être assurée par le pare-vapeur. Un même inconvénient peut être souligné avec le dispositif d'entretoisement du brevet FR-2.649.740 . On est donc à la recherche de solutions limitant le nombre d'organes de fixation sans nuire aux possibilités de réglage en écartement d'un tel dispositif d'entretoisement et sans nuire à l'étanchéité de l'ensemble.Another example of a bracing device is provided in the European patent EP-0236224 . In such a bracing device, the base is formed of a spider to the right of the central zone of which is provided a bracing member constituted by a hollow tube. Fixing the base to the reference surface is made by screwing. For this purpose, each branch of the cross comprises a through hole for its attachment to the reference surface. However, more and more often, the reference surfaces to be equipped with a facing are sealed with a vapor barrier film. The attachment of a cross, as mentioned above, therefore generates a multiplication of holes impairing the seal to be provided by the vapor barrier. The same drawback can be emphasized with the patent bracing device FR-2649740 . We are therefore looking for solutions limiting the number of fasteners without interfering with the possibilities of adjusting spacing of such a spacer device and without impairing the tightness of the assembly.

Un but de la présente invention est donc de proposer un dispositif d'entretoisement du type précité dont la conception permet de fixer le dispositif d'entretoisement à la surface de référence à l'aide d'un seul organe de fixation en garantissant l'efficacité du pare-vapeur et sans nuire à la possibilité de réglage de l'écartement du rail par rapport à la surface de référence.An object of the present invention is therefore to provide a bracing device of the aforementioned type whose design allows to fix the bracing device to the reference surface with a single fastener ensuring efficiency of the vapor barrier and without affecting the possibility of adjusting the distance of the rail relative to the reference surface.

Un autre but de la présente invention est de proposer un dispositif d'entretoisement dont la conception permet, de manière simple, d'empêcher toute désolidarisation du support dudit corps lors du réglage en écartement dudit support.Another object of the present invention is to provide a bracing device whose design allows, in a simple manner, to prevent any separation of the support of said body when adjusting spaced said support.

Un autre but de la présente invention est de proposer un dispositif d'entretoisement dont la conception permet, de manière simple, de fixer de manière étanche, le dispositif d'entretoisement à la surface de référence.Another object of the present invention is to provide a bracing device whose design allows, in a simple manner, to fix tightly, the bracing device to the reference surface.

Grâce à cette conception du dispositif d'entretoisement, dans laquelle le siège de la vis est formé par l'extrémité du corps de la base opposée à l'extrémité d'appui dudit corps et la tête de vis forme la butée de retenue du support sur le corps de la base, il est possible de maintenir une étanchéité entre tête de vis et siège, y compris pendant les phases de réglage de l'écartement du support par rapport à la surface de référence sans nuire au montage/démontage du support du corps tubulaire de la base, ce montage/démontage pouvant s'effectuer par l'extrémité opposée à l'extrémité d'appui dudit corps tubulaire.Thanks to this design of the bracing device, in which the seat of the screw is formed by the end of the body of the base opposite the bearing end of said body and the screw head forms the retaining stop of the support on the body of the base, it is possible to maintain a seal between screw head and seat, including during the adjustment phase of the spacing of the support relative to the reference surface without affecting the assembly / disassembly of the support of the tubular body of the base, this assembly / disassembly being effected by the end opposite to the bearing end of said tubular body.

Grâce à cette conception, le dispositif permet en outre, à l'aide d'un seul organe de fixation, la fixation de la base à la surface de référence et le maintien du support sur la base tout en empêchant toute désolidarisation du support du corps de la base lors du réglage en écartement dudit support.With this design, the device also allows, with the aid of a single fastener, fixing the base to the reference surface and maintaining the support on the base while preventing any separation of the support body of the base when adjusting the spacing of said support.

Selon une forme de réalisation préférée de l'invention, la butée de retenue du support sur le corps réalisée d'une seule pièce avec la tête de vis est formée par au moins une partie de la tête de vis en saillie radiale par rapport au corps de la base à l'état introduit de la vis dans le corps de la base et en position de fin de course d'introduction de la vis dans ledit corps.According to a preferred embodiment of the invention, the support retaining stop on the body made in one piece with the screw head is formed by at least a portion of the screw head projecting radially from the body from the base to the inserted state of the screw in the body of the base and in the end position of insertion of the screw into said body.

De préférence, la tête de vis est équipée de moyens qui, en position d'appui de la tête de vis sur l'extrémité du corps de la base, sont configurés pour permettre un contact d'appui étanche avec ladite extrémité du corps de la base.Preferably, the screw head is equipped with means which, in the support position of the screw head on the end of the body of the base, are configured to allow a sealing contact with said end of the body of the body. based.

L'extrémité du corps de la base opposée à l'extrémité d'appui dudit corps est chanfreinée dans l'épaisseur de la paroi dudit corps pour conférer au corps une forme extérieure parfaitement circulaire au niveau de ladite extrémité du corps de la base. Cette extrémité du corps de la base, opposée à l'extrémité d'appui dudit corps, présente un diamètre périphérique interne inférieur au diamètre du passage axial traversant du support pour permettre un montage/démontage aisé du support du corps de la base par l'extrémité dudit corps opposée à l'extrémité d'appui dudit corps.The end of the body of the base opposite the bearing end of said body is chamfered in the thickness of the wall of said body to give the body a perfectly circular outer shape at said end of the body of the base. This end of the body of the base, opposite to the bearing end of said body, has an inner peripheral diameter smaller than the diameter of the axial passage through the support to allow a easy assembly / disassembly of the base body support by the end of said body opposite to the support end of said body.

Grâce à ces dispositions, il devient aisé d'obtenir une liaison étanche entre vis et base garantissant une efficacité maximale du pare-vapeur susceptible d'équiper la surface de référence à revêtir d'un parement.With these provisions, it becomes easy to obtain a tight connection between screw and base ensuring maximum efficiency of the vapor barrier may equip the reference surface to be covered with a facing.

Comme mentionné ci-dessus, le dispositif d'entretoisement, objet de l'invention, est destiné à permettre le maintien à écartement réglable d'un rail 6, généralement métallique, en forme de U, par rapport à une surface 1 de référence. Dans la plupart des cas, il est en effet nécessaire de maintenir un vide appelé vide technique entre le rail 6 et la surface 1 de référence pour permettre notamment le passage de gaine. Le dispositif d'entretoisement a donc pour fonction de maintenir le rail 6 écarté d'une distance réglable de la surface 1 de référence à l'état assujetti du rail 6 à la surface 1 de référence. Cette surface 1 de référence peut être constituée par un mur, un plafond, un plancher ou toute autre surface devant être revêtue d'un parement 7. Sur cette surface 1 de référence, il est généralement positionné une série de dispositifs d'entretoisement, de préférence sous forme de lignes parallèles, chaque ligne servant à la réception d'au moins un rail 6 fixé à la ligne de dispositif d'entretoisement par encliquetage. Le parement 7, se présentant par exemple sous forme de lame ou de panneau, tel qu'une plaque de plâtre, est alors fixé généralement par vissage à l'aide d'une vis représentée en 8 aux figures à la surface du rail 6. On note que dans les exemples représentés ci-dessous, l'élément de parement est une plaque de plâtre et le rail 6 est un rail profilé en U à double retour interne.As mentioned above, the bracing device, object of the invention, is intended to allow the maintenance of adjustable spacing of a rail, 6 generally U-shaped metal, relative to a reference surface 1. In most cases, it is indeed necessary to maintain a empty called technical gap between the rail 6 and the reference surface 1 to allow in particular the passage of sheath. The bracing device therefore has the function of keeping the rail 6 spaced from an adjustable distance from the reference surface 1 to the secured state of the rail 6 to the reference surface 1. This reference surface 1 may be constituted by a wall, a ceiling, a floor or any other surface to be coated with a facing 7. On this reference surface 1, it is generally positioned a series of bracing devices, preferably in the form of parallel lines, each line serving to receive at least one rail 6 fixed to the line of snap-fastening device. The facing 7, for example in the form of a blade or panel, such as a plasterboard, is then fixed generally by screwing with a screw shown at 8 to the figures on the surface of the rail 6. It is noted that in the examples shown below, the facing element is a gypsum board and the rail 6 is an internal double-return U-profile rail.

Comme mentionné ci-dessus, la surface 1 de référence à revêtir du parement 7 est généralement étanchéifiée à l'aide d'un film pare-vapeur représenté en 2 aux figures. Le but de la présente invention est donc de limiter le nombre de perçages dans ce pare-vapeur 2 et de maintenir l'étanchéité. Le dispositif d'entretoisement comprend donc un support 5 du genre plot sur lequel le rail 6 est apte à s'encliqueter et une base 3 de fixation du support 5 à la surface 1 de référence. La base 3 comprend un corps 9 tubulaire muni à l'une de ses extrémités, représentée en 9B aux figures et dite extrémité d'appui, d'une surface 17 d'appui sur la surface 1 de référence. Cette surface 17 d'appui s'étend perpendiculairement à l'axe longitudinal dudit corps 9 qui est ici représenté sous forme d'un corps creux cylindrique taraudé ouvert à chacune de ses extrémités, le taraudage dudit corps étant représenté en 10 aux figures. Ledit support 5 du genre plot est quant à lui muni d'un passage 13 axial traversant pour pouvoir être enfilé et monté sur le corps 9 tubulaire de la base 3 à écartement réglable par rapport à la surface 17 d'appui dudit corps.As mentioned above, the reference surface 1 to be coated with the facing 7 is generally sealed with a vapor barrier film shown at 2 in the figures. The purpose of the present invention is therefore to limit the number of holes in the vapor barrier 2 and maintain the seal. The bracing device thus comprises a support 5 of the kind of pad on which the rail 6 is adapted to snap and a base 3 for fixing the support 5 to the reference surface 1. The base 3 comprises a tubular body 9 provided at one of its ends, shown at 9B in the figures and said support end, with a bearing surface 17 on the reference surface 1. This bearing surface 17 extends perpendicularly to the longitudinal axis of said body 9 which is here shown in the form of a tapped cylindrical hollow body open at each of its ends, the tapping of said body being shown at 10 in the figures. Said support 5 of the kind of pad is itself provided with a passage 13 through axial to be threaded and mounted on the tubular body 9 of the base 3 spacing adjustable relative to the bearing surface 17 of said body.

Du fait de la configuration de l'extrémité 9A du corps 9 tubulaire opposée à l'extrémité 9B dudit corps, en particulier du fait que l'extrémité du corps de la base, opposée à l'extrémité d'appui dudit corps, présente un diamètre périphérique interne inférieur au diamètre du passage axial traversant du support, un montage/démontage aisé du support du corps de la base par l'extrémité dudit corps opposée à l'extrémité d'appui dudit corps est possible.Due to the configuration of the end 9A of the tubular body 9 opposite the end 9B of said body, in particular because the end of the body of the base, opposite to the bearing end of said body, has a internal peripheral diameter less than the diameter of the axial passage passing through the support, easy mounting / dismounting of the support of the body of the base by the end of said body opposite the bearing end of said body is possible.

Le dispositif comporte en outre une vis 4 apte à être vissée dans le corps 9 de la base jusqu'à faire saillie de la surface 17 d'appui pour solidariser la base 3 à la surface 1 de référence.The device further comprises a screw 4 adapted to be screwed into the body 9 of the base until protruding from the bearing surface 17 to secure the base 3 to the reference surface 1.

De manière caractéristique à l'invention, la vis 4 de solidarisation de la base 3 à la surface 1 de référence, de longueur supérieure à la longueur du corps 9 de la base, présente une tête 4A de vis qui, à l'état monté du support 5 sur le corps 9 de la base et, en position de fin de course d'introduction de la vis dans ledit corps 9 est en appui contre l'extrémité 9A du corps de la base 3 opposée à l'extrémité 9B d'appui dudit corps et obture au moins partiellement, de préférence ferme de manière étanche, ladite extrémité 9A du corps de la base. Dans ladite position d'appui de la tête 4A de vis sur l'extrémité 9A du corps de la base, la tête de vis forme la butée 18 de retenue du support 5 sur le corps 9 de la base, ce support 5 étant monté mobile axialement le long dudit corps 9 de la base entre une position d'écartement minimal de la surface 17 d'appui et une position d'écartement maximal de la surface 17 d'appui dans laquelle il est directement en appui contre la tête de vis. Par ailleurs, la surface 17 d'appui du corps 9 perpendiculaire à l'axe longitudinal du corps 9 s'étend en affleurement de l'extrémité d'appui dudit corps 9. Cette disposition permet à nouveau de garantir l'étanchéité au niveau du pare-vapeur.In a manner characteristic of the invention, the screw 4 for securing the base 3 to the reference surface 1, which is longer than the length of the body 9 of the base, has a screw head 4A which, in the assembled state of the support 5 on the body 9 of the base and, in end of insertion insertion position of the screw in said body 9 bears against the end 9A of the body of the base 3 opposite the end 9B of support of said body and at least partially closes, preferably tightly closed, said end 9A of the body of the base. In said support position of the screw head 4A on the end 9A of the body of the base, the screw head forms the abutment 18 for retaining the support 5 on the body 9 of the base, this support 5 being mounted movably axially along said body 9 of the base between a position of minimum separation of the bearing surface 17 and a position of maximum separation of the bearing surface 17 in which it is directly in abutment against the screw head. Furthermore, the support surface 17 of the body 9 perpendicular to the longitudinal axis of the body 9 extends flush with the bearing end of said body 9. This provision again makes it possible to guarantee the seal at the level of the vapor barrier.

Dans les exemples représentés, la butée 18 de retenue du support 5 sur le corps 9 de la base, réalisée d'une seule pièce avec la tête 4A de vis, est formée par au moins une partie 4B de la tête 4A de vis en saillie radiale par rapport au corps 9 de la base à l'état vissé de ladite vis 4 dans ledit corps 9 de la base. Cette solution se caractérise par sa simplicité et permet un montage/démontage aisé du support 5 du genre plot du corps 9 tubulaire de la base.In the examples shown, the abutment 18 for retaining the support 5 on the body 9 of the base, made in one piece with the screw head 4A, is formed by at least a portion 4B of the projecting screw head 4A. radial to the body 9 of the base in the screwed state of said screw 4 in said body 9 of the base. This solution is characterized by its simplicity and allows easy assembly / disassembly of the support 5 of the kind stud of the tubular body 9 of the base.

La vis 4 de solidarisation de la base 3 à la surface 1 de référence, de longueur supérieure à la longueur du corps 9 de la base, présente, à l'état introduit dans le corps 9 de la base, au moins une position de fin de course dans laquelle la tête 4A de vis est en appui contre une extrémité 9A du corps de la base et obture au moins partiellement ladite extrémité 9A, la partie du corps 4C de vis servant à la fixation de la base à la surface de référence faisant saillie de l'extrémité 9B opposée, dite d'appui, du corps 9 de la base.The screw 4 for securing the base 3 to the reference surface 1, which is longer than the length of the body 9 of the base, has, in the state introduced into the body 9 of the base, at least one end position in which the head 4A of the screw bears against one end 9A of the body of the base and at least partially closes off said end 9A, the portion of the body 4C of screws serving for fixing the base to the reference surface forming projection of the opposite end 9B, said support, the body 9 of the base.

De préférence, la tête 4A de vis est, en position d'appui sur l'extrémité 9A du corps 9 de la base, en contact d'appui étanche avec ladite extrémité 9A dudit corps 9.Preferably, the screw head 4A is, in a bearing position on the end 9A of the body 9 of the base, in sealing contact with said end 9A of said body 9.

Ainsi, la vis 4 qui ferme de manière étanche l'extrémité 9A du corps 9 tubulaire empêche tout passage d'air depuis le perçage effectué dans la surface 1 de référence en direction de l'extérieur. L'efficacité du pare-vapeur 2 est donc maintenue.Thus, the screw 4 sealingly closing the end 9A of the tubular body 9 prevents any passage of air from the drilling performed in the reference surface 1 towards the outside. The effectiveness of the vapor barrier 2 is therefore maintained.

Pour assurer une telle étanchéité, les surfaces de la tête 4A de vis et de l'extrémité 9A du corps 9 de la base aptes à venir en contact, en position d'appui de la tête 4A de vis sur l'extrémité 9A dudit corps 9, sont des surfaces de forme complémentaire.To ensure such a seal, the surfaces of the screw head 4A and the end 9A of the body 9 of the base adapted to come into contact, in the support position of the screw head 4A on the end 9A of said body 9, are surfaces of complementary shape.

Dans les exemples représentés, l'extrémité 9A du corps de la base, apte à venir en contact avec la tête 4A de la vis, est chanfreinée dans l'épaisseur dudit corps 9 et la tête 4A de la vis est une tête conique. Le corps 4C de la vis est quant à lui un corps cylindrique.In the examples shown, the end 9A of the body of the base, adapted to come into contact with the head 4A of the screw, is chamfered in the thickness of said body 9 and the head 4A of the screw is a conical head. The body 4C of the screw is a cylindrical body.

Pour permettre un réglage en écartement du support 5 par rapport à la surface 17 d'appui du corps 9, le support 5 est réalisé de manière à pouvoir être déplacé le long dudit corps 9. Dans les exemples représentés, le corps 9 tubulaire de la base 3 est fileté, le filetage étant représenté en 11 et le passage 13 axial traversant du support 5 est taraudé, le taraudage étant représenté en 14 pour permettre, par entraînement en rotation du support 5 par rapport audit corps 9 de la base, le réglage en écartement du support 5 par rapport à la surface 17 d'appui dudit corps 9. Le corps 9 tubulaire et le support 5 taraudé sont ainsi assimilables à un ensemble vis/écrou, le support 5 du genre plot constituant l'équivalent d'une bague écrou. Le corps 9 tubulaire de la base 3 peut être quant à lui taraudé ou non.To allow adjustment in spacing of the support 5 with respect to the surface 17 of support of the body 9, the support 5 is made to be movable along said body 9. In the examples shown, the tubular body 9 of the base 3 is threaded, the thread being shown at 11 and the passage 13 axial through the support 5 is threaded, the tapping being shown at 14 to allow, by rotating the support 5 relative to the body 9 of the base, the spacing adjustment of the support 5 relative to the support surface 17 9. The tubular body 9 and the threaded support 5 are thus comparable to a screw / nut assembly, the support 5 of the stud type constituting the equivalent of a nut ring. The tubular body 9 of the base 3 may be threaded or not.

La figure 1 représente la position d'écartement minimale du support 5 par rapport à la surface 17 d'appui et, par suite, à la surface 1 de référence, et la figure 2, la position d'écartement maximale du support 5 par rapport à la surface 17 d'appui et, par suite, à la surface 1 de référence, la tête de vis formant, dans cette position, une butée de fin de course du support 5.The figure 1 represents the minimum distance position of the support 5 with respect to the support surface 17 and, consequently, to the reference surface 1, and the figure 2 , the position of maximum spacing of the support 5 relative to the bearing surface 17 and, consequently, to the reference surface 1, the screw head forming, in this position, an end stop of the support 5 .

Dans les exemples représentés, le corps 9 tubulaire, qui est un corps creux cylindrique ouvert à chacune de ses extrémités, n'est fileté que sur une partie de sa longueur représentée en A à la figure 2 limitant la course de réglage du support à ladite longueur. Ce filetage aurait pu, de manière équivalente, s'étendre sur la totalité du corps 9 de la base. Ce filetage aurait pu être remplacé par une surface crantée, le support étant apte, à l'état enfilé sur le corps, à passer d'un cran à un autre, chaque cran correspondant à une position de réglage dudit support.In the examples shown, the tubular body 9, which is a cylindrical hollow body open at each of its ends, is threaded only over part of its length, represented at figure 2 limiting the adjustment stroke of the support to said length. This thread could have, in an equivalent manner, extend over the entire body 9 of the base. This thread could have been replaced by a toothed surface, the support being adapted, in the state threaded on the body, to pass from one notch to another, each notch corresponding to a setting position of said support.

Indépendamment du mode de réalisation, le corps 9 de la base présente une longueur telle, qu'en position d'appui de la tête 4A de vis sur l'extrémité 9A, opposée à l'extrémité 9B d'appui, du corps 9 de la base et à l'état enfilé du support 5 sur ledit corps 9 de base, le support 5 monté mobile axialement le long du corps 9 de base entre une position d'écartement maximal de la surface 17 d'appui du corps 9 de base et une position de rapprochement maximal de ladite surface présente une course de déplacement au moins égale à 1/4, de préférence à au moins 1/3, de la longueur totale du corps 9 de la base.Independently of the embodiment, the body 9 of the base has a length such that in the support position of the head 4A of the screw on the end 9A, opposite the end 9B support, the body 9 of the base and the threaded state of the support 5 on said base body 9, the support 5 mounted axially movable along the base body 9 between a position of maximum separation of the bearing surface 17 of the base body 9 and a position of maximum approximation of said surface has a displacement path of at least 1/4, preferably at least 1/3, of the total length of the body 9 of the base.

Dans les exemples représentés, le support 5 se présente sous forme d'un plot inscrit dans un cercle, ce plot comprenant une tête 15 tronconique prolongée d'un pied 16, pied 16 et tête 15 étant traversés par le passage 13 traversant apte à recevoir la vis 4 de fixation de la base 3 à la surface 1 de référence, ladite tête 15 étant coaxiale audit passage 13 pour pouvoir occuper une position angulaire quelconque autour de la vis 4 de fixation en autorisant un encliquetage du rail 6 dans l'une quelconque desdites positions. A l'état vissé de la vis 4 dans le corps 9, la tête 15 du plot s'étend au moins partiellement au-delà de la tête de vis. Cette partie en saillie du support 5 par rapport au reste du dispositif permet un encliquetage aisé du rail 6 sur ledit support 5, en particulier la tête 15 du plot constitutif du support.In the examples shown, the support 5 is in the form of a stud inscribed in a circle, this stud comprising a prolonged frustoconical head 15 of a foot 16, foot 16 and head 15 being traversed by the through passage 13 adapted to receive the screw 4 for fixing the base 3 to the reference surface 1, said head 15 being coaxial with said passage 13 so as to occupy any angular position around the fastening screw 4 by allowing the rail 6 to snap into any one of said positions. In the screwed state of the screw 4 in the body 9, the head 15 of the stud extends at least partially beyond the screw head. This projecting portion of the support 5 relative to the rest of the device allows easy snapping of the rail 6 on said support 5, in particular the head 15 of the constituent block of the support.

En particulier, le passage 13 axial traversant du support 5 est un passage taraudé cylindrique dans le pied 16 dudit plot qui se prolonge en s'élargissant, en particulier en s'évasant, dans la tête 15 dudit plot pour former un passage, généralement lisse, de préférence conique dans ladite tête 15. Le taraudage dudit passage 13 est représenté en 14 aux figures.In particular, the axial passage 13 passing through the support 5 is a cylindrical threaded passage in the foot 16 of said stud which extends in widening, in particular flaring, in the head 15 of said stud to form a passage, generally smooth , preferably conical in said head 15. The tapping of said passage 13 is shown at 14 in the figures.

La surface 17 d'appui de la base 3 de fixation sur la surface 1 de référence est formée par l'une des faces d'une platine évidée, ledit évidement formant le débouché du corps 9 tubulaire porté par la face opposée de ladite platine 17.The bearing surface 17 of the fixing base 3 on the reference surface 1 is formed by one of the faces of a recessed plate, said recess forming the outlet of the tubular body 9 carried by the opposite face of said plate 17 .

Dans les exemples représentés, la platine est une platine circulaire, évidée centralement.In the examples shown, the plate is a circular plate, hollowed out centrally.

De préférence encore, le corps 9 tubulaire et la surface 17 d'appui de la base 3 de fixation sur la surface 1 de référence sont réalisés d'un seul tenant.More preferably, the tubular body 9 and the bearing surface 17 of the fixing base 3 on the reference surface 1 are made in one piece.

Toutefois, de manière équivalente, la base aurait pu être formée d'un corps tubulaire rapporté sur la surface d'appui formée d'une platine, par exemple circulaire, évidée centralement sur laquelle le corps 9 tubulaire viendrait se verrouiller par exemple par un montage baïonnette. Cette solution n'est pas préférée.However, equivalently, the base could have been formed of a body tubular attached to the support surface formed of a plate, for example circular, recessed centrally on which the tubular body 9 would be locked for example by bayonet mounting. This solution is not preferred.

Le procédé de pose d'un tel dispositif d'entretoisement s'opère de la manière suivante. La base 3, le support 5 et la vis 4 sont pré-assemblés. A cet effet, le support 5 est enfilé côté extrémité 9A du corps 9 tubulaire sur la base 3 par son pied 16 et vissé sur le corps par coopération du taraudage 14 du pied 16 avec le filetage 11 dudit corps 9. La vis 4 est ensuite introduite dans le corps 9 tubulaire en passant à travers le support 5. Cette vis 4 est vissée à la surface 1 de référence. Les positions de la base 3 sur la surface 1 de référence ont été repérées par l'opérateur. L'ensemble base, support, vis peut être fixé à la surface 1 de référence par vissage à l'aide de la vis 4. La vis 4 traverse le pare-vapeur 2 pour venir se fixer dans le reste de la surface 1 de référence. Après vissage complet, la tête 4A de la vis 4 est en appui sur l'extrémité 9A du corps 9 de la base qui comprime, via la platine 17, le pare-vapeur 2 sur la surface 1 de référence. La tête 4A de la vis 4 obstrue l'extrémité 9A du corps de la base qui a été chanfreinée à l'identique de la tête 4A de la vis assurant ainsi l'étanchéité de l'ensemble. La tête de la vis 4 présente un diamètre supérieur au diamètre du passage taraudé ménagé dans le pied 16 du plot du support 5. Le support 5 ne peut donc pas être séparé de la base. Une partie du plot, en particulier la zone de transition pied/tête de plot, vient donc en butée contre la tête 4A de vis en position de réglage d'écartement maximal du support 5 par rapport à la surface 17 d'appui de la base. L'amplitude du réglage du support 5 le long du corps représenté en L est déterminée par la différence entre la longueur du filetage 11 du corps 9 de la base 3 et la longueur du taraudage 14 du support 5. Après réglage à la bonne distance du support 5 par rapport à la surface 17 d'appui et par suite de la surface 1 de référence, le rail 6, encore appelé fourrure, est encliqueté sur le support 5. Les plaques de plâtre 7 sont ensuite fixées de manière traditionnelle sur le rail 6 à l'aide de vis représentées en 8.The method of laying such a bracing device operates in the following manner. The base 3, the support 5 and the screw 4 are pre-assembled. For this purpose, the support 5 is threaded end-side 9A of the tubular body 9 on the base 3 by its foot 16 and screwed onto the body by cooperation of the tapping 14 of the foot 16 with the thread 11 of said body 9. The screw 4 is then introduced into the tubular body 9 passing through the support 5. This screw 4 is screwed to the reference surface 1. The positions of the base 3 on the reference surface 1 have been identified by the operator. The base assembly, support, screw can be fixed to the reference surface 1 by screwing with the screw 4. The screw 4 passes through the vapor barrier 2 to be fixed in the rest of the reference surface 1 . After complete screwing, the head 4A of the screw 4 bears on the end 9A of the body 9 of the base which compresses, via the plate 17, the vapor barrier 2 on the reference surface 1. The head 4A of the screw 4 obstructs the end 9A of the body of the base which has been chamfered identical to the head 4A of the screw thereby sealing the assembly. The head of the screw 4 has a diameter greater than the diameter of the threaded passage in the foot 16 of the support pad 5. The support 5 can not be separated from the base. Part of the stud, in particular the transition zone foot / pad head, therefore abuts against the screw head 4A in the position of setting the maximum spacing of the support 5 with respect to the bearing surface 17 of the base . The amplitude of the adjustment of the support 5 along the body shown in L is determined by the difference between the length of the thread 11 of the body 9 of the base 3 and the length of the tapping 14 of the support 5. After adjustment at the proper distance from the support 5 relative to the bearing surface 17 and as a result of the reference surface 1, the rail 6, also called fur, is snapped onto the support 5. The plasterboard 7 are then conventionally fixed to the rail 6 with screws shown at 8.

La base et le support peuvent être réalisés en tout type de matériau métallique, composite ou de synthèse. Le dispositif d'entretoisement tel que décrit ci-dessus se caractérise par sa simplicité de pose sans nuire à l'étanchéité du pare-vapeur, ni aux possibilités de réglage en écartement du rail par rapport à la surface de référence.The base and the support may be made of any type of metallic, composite or synthetic material. The bracing device as described above is characterized by its simplicity of installation without impairing the sealing of the vapor barrier, nor the adjustment possibilities in spacing of the rail relative to the reference surface.
