Description

La présente invention concerne un système à joint destiné à la décoration, la réalisation de motifs ou l'arrêt de couleurs sur des enduits appliqués sur une façade ou un autre mur extérieur ou intérieur.The present invention relates to a joint system intended for decoration, the production of patterns or the stopping of colors on coatings applied to a facade or another exterior or interior wall.

Plus particulièrement, l'invention vise un système à joint comportant une baguette creuse décorative affleurant par l'extrémité de ses bords la surface extérieure d'un enduit appliqué contre un mur, la baguette étant ouverte du côté opposé au mur. Un dispositif de fixation, par rapport auquel la baguette est montée coulissante, assure une liaison entre le mur et la baguette.More particularly, the invention relates to a joint system comprising a decorative hollow strip flush with the end of its edges the external surface of a coating applied against a wall, the strip being open on the side opposite the wall. A fixing device, relative to which the rod is slidably mounted, ensures a connection between the wall and the rod.

Ce type de système à joint est décrit par le brevet FR 2 097 089. De tels systèmes à joints connus comportent une baguette directement appliquée contre le mur et présentent généralement des problèmes d'étanchéité à la jonction de la baguette et de l'enduit, de sorte que l'humidité peut s'infiltrer à cet endroit jusqu'au mur. Ce défaut d'étanchéité est dû, au moins partiellement, à la différence des coefficients de dilatation des matières constituant l'enduit d'une part et la baguette d'autre part.This type of joint system is described by patent FR 2 097 089. Such known joint systems comprise a rod directly applied against the wall and generally have sealing problems at the junction of the rod and the coating, so that moisture can infiltrate there up to the wall. This leak is due, at least partially, to the difference in the expansion coefficients of the materials making up the coating on the one hand and the strip on the other.

De plus, dans la mesure où la baguette creuse de ces systèmes à joints connus est directement appliquée contre le mur, son réglage latéral est rendu malaisé du fait des irrégularités du mur.In addition, since the hollow rod of these known joint systems is applied directly against the wall, its lateral adjustment is made difficult because of irregularities in the wall.

En outre, la liaison coulissante entre la baguette et le dispositif de fixation rend indispensable une conformation particulière du fond ouvert de la baguette, ce qui nécessite de donner une surépaisseur au moins à certains endroits du fond.In addition, the sliding connection between the rod and the fixing device makes it necessary to have a particular conformation of the open bottom of the rod, which requires giving an extra thickness at least in certain places of the bottom.

La présente invention a pour but de supprimer ces inconvénients et tout au moins de les atténuer, et propose un système à joint du type susmentionné qui, tout en étant fixé sur le mur de façon initialement réglable, permet l'application d'une couche d'enduit entre la face arrière de la baguette et le mur empêchant ainsi toute infiltration d'humidité. Ainsi, le mur est recouvert d'une couche d'enduit généralement continue, éventuellement interrompue sur une zone de très faible étendue par le dispositif de fixation si celui-ci est ancré dans le mur.The present invention aims to eliminate these drawbacks and at least to reduce them, and proposes a joint system of the aforementioned type which, while being fixed to the wall in an initially adjustable manner, allows the application of a layer of coating between the rear side of the strip and the wall thus preventing any ingress of moisture. Thus, the wall is covered with a layer of generally continuous plaster, possibly interrupted over an area of very small extent by the fixing device if the latter is anchored in the wall.

Ce but est atteint du fait que le système à joint comporte au moins un coulisseau qui coiffe la partie arrière de la baguette et la guide librement en translation, et que le dispositif de fixation est agencé de façon à supporter chaque coulisseau et à le maintenir dans l'enduit, mais écarté du mur d'une distance prédéterminée.This object is achieved by the fact that the joint system comprises at least one slide which covers the rear part of the rod and guides it freely in translation, and that the fixing device is arranged so as to support each slide and keep it in the plaster, but away from the wall by a predetermined distance.

Ainsi, le dispositif de fixation ne coopère pas directement avec la baguette et empêche que les différences des coefficients de dilatation de la baguette et de l'enduit conduisent à des contraintes susceptibles d'être à l'origine de fissures capables de se propager dans l'enduit jusqu'au mur.Thus, the fixing device does not cooperate directly with the strip and prevents the differences in the expansion coefficients of the strip and the coating from leading to stresses liable to be the source of cracks capable of propagating in the plaster to the wall.

La pose terminée, la baguette creuse affleure par l'extrémité de ses bords la surface extérieure de l'enduit et les coulisseaux sont finalement noyés dans l'enduit, de telle sorte que le dispositif est capable de se dilater sans détruire l'étanchéité de l'enduit.Once the installation is complete, the hollow strip is flush with the end of its edges on the exterior surface of the plaster and the slides are finally embedded in the plaster, so that the device is able to expand without destroying the sealing of the coating.

L'invention prévoit, suivant un mode de réalisation particulier, l'utilisation d'un dispositif de fixation qui ne nécessite pas un ancrage dans le mur.The invention provides, according to a particular embodiment, the use of a fixing device which does not require anchoring in the wall.

En effet, les coulisseaux peuvent être maintenus fixés dans l'enduit et écartés du mur d'une distance voulue par une couche de ciment colle ou de mastic colle appliquée sur le mur sur une épaisseur désirée. Il est procédé au réglage de l'écartement des coulisseaux par rapport au mur à l'aide d'une cale ou d'une jauge amovible.In fact, the sliders can be kept fixed in the plaster and separated from the wall by a desired distance by a layer of adhesive cement or adhesive sealant applied to the wall to a desired thickness. The spacing of the slides is adjusted to the wall using a shim or a removable gauge.

Ce type de dispositif de fixation n'interrompt pas la couche d'enduit qui recouvre le mur de façon continue.This type of fixing device does not interrupt the coating layer which covers the wall continuously.

Il est également possible d'utiliser un dispositif de fixation ancré dans le mur. Dans ce cas, il est avantageux que le coulisseau comporte une partie médiane plane, dans laquelle une ouverture circulaire est pratiquée pour permettre le passage du dispositif de fixation.It is also possible to use a fixing device anchored in the wall. In this case, it is advantageous for the slide to have a flat central part, in which a circular opening is made to allow the passage of the fixing device.

Ce dispositif de fixation se présente avantageusement comme un organe de forme générale cylindrique. Une partie de tige dotée de nervures est destinée à être enfoncée dans un trou foré dans le mur. Les nervures qui servent à renforcer l'ancrage dans le mur sont éventuellement circulaires et peuvent être remplacées par un dispositif équivalent.This fixing device is advantageously presented as a generally cylindrical member. A part of the rod with ribs is intended to be inserted into a hole drilled in the wall. The ribs which serve to reinforce the anchoring in the wall are possibly circular and can be replaced by an equivalent device.

Cet organe de fixation comporte également une tête plate ou bride servant de retenue contre le bord de l'ouverture pratiquée dans la partie médiane du coulisseau.This fixing member also comprises a flat head or flange serving to retain against the edge of the opening made in the middle part of the slide.

Suivant un mode préfére de réalisation, la partie de l'organe de fixation située entre la tête et la tige nervurée a un diamètre supérieur à celui du trou foré dans le mur et tel que l'organe de fixation puisse être enfoncé à force dans l'ouverture du coulisseau. Cette partie, de longueur prédéterminée, assure ainsi une distance choisie d'écartement entre le coulisseau et le mur.According to a preferred embodiment, the part of the fixing member situated between the head and the ribbed rod has a diameter greater than that of the hole drilled in the wall and such that the fixing member can be forced into the opening of the slide. This part, of length predetermined, thus ensures a chosen distance of spacing between the slide and the wall.

Il est préférable que le diamètre de cette partie d'écartement reste suffisamment petit pour que l'étendue de la zone d'interruption de l'enduit soit faible.It is preferable that the diameter of this spacer part remains small enough so that the extent of the coating interruption zone is small.

Un organe de fixation de ce type simplifie et accélère considérablement la pose du système à joint. En effet, après la mise en position du système prémonté, avec un enfoncement partiel de l'organe de fixation dans les trous forés dans le mur, une première couche d'enduit est appliquée, il est ensuite procédé à l'enfoncement complet et au réglage de l'alignement. Enfin, une deuxième couche d'enduit est projetée. Il n'est pas nécessaire d'attendre le séchage de la première couche d'enduit pour appliquer la deuxième, dans la mesure où le dispositif de fixation maintient le système en position, même si l'enduit est humide. De plus, lors de l'enfoncement complet, la tige nervurée de l'organe de fixation est susceptible d'entraîner une partie de la première couche d'enduit dans les trous forés dans le mur, ce qui améliore la qualité de l'étanchéité.A fastener of this type considerably simplifies and accelerates the installation of the joint system. Indeed, after the positioning of the pre-assembled system, with a partial depression of the fixing member in the holes drilled in the wall, a first layer of plaster is applied, it is then proceeded to the full depression and the alignment adjustment. Finally, a second layer of plaster is sprayed. It is not necessary to wait for the first coating to dry before applying the second, since the fixing device keeps the system in position, even if the coating is wet. In addition, when fully inserted, the ribbed rod of the fixing member is capable of entraining part of the first layer of plaster in the holes drilled in the wall, which improves the quality of the seal. .

Pour éviter que la tête de l'organe de fixation ne nuise au guidage en translation de la baguette dans le coulisseau, celui-ci peut être muni d'épaulements ménageant un logement adapté à la dimension de cette tête et la plaçant en retrait par rapport à la face arrière de la baguette.To prevent the head of the fixing member from interfering with the guide in translation of the rod in the slide, the latter can be provided with shoulders providing a housing adapted to the size of this head and placing it in withdrawal with respect to on the back of the stick.

Suivant un mode particulier de réalisation de l'invention, les bords de la baguette creuse présentent en coupe la forme d'un crochet. Ces bords sont repliés vers l'intérieur de l'enduit et montrent une nervure avec une gorge intérieure tournée vers le mur. Cette conformation permet d'améliorer l'ancrage dans l'enduit qui arase le sommet de ces nervures, c'est-à-dire la partie de la baguette située à la plus grande distance du mur. Les nervures sont telles que leur extrémité tournée vers le mur, la pointe du crochet vu en coupe, est séparée de la face du coulisseau tournée vers la baguette, d'une distance permettant l'interposition de l'enduit même à cet endroit.According to a particular embodiment of the invention, the edges of the hollow rod have in section the shape of a hook. These edges are folded towards the inside of the plaster and show a rib with an interior groove facing the wall. This conformation makes it possible to improve the anchoring in the coating which level the top of these ribs, that is to say the part of the strip situated at the greatest distance from the wall. The ribs are such that their end facing the wall, the point of the hook seen in section, is separated from the face of the slide facing the rod, by a distance allowing the interposition of the coating even at this location.

Suivant un autre mode de réalisation, la baguette est adaptée à la protection de fissures.According to another embodiment, the rod is suitable for protecting cracks.

En effet, dans le cas d'une habitation ou d'un immeuble à un ou plusieurs étages, il arrive souvent que des fissures horizontales se forment dans le mur extérieur, le long de la ligne où le plancher et le mur se rejoignent. De telles fissures peuvent se propager dans l'épaisseur du mur jusqu'à la façade et constituer une zone d'infiltration d'eau nuisible à l'édifice.Indeed, in the case of a dwelling or a building with one or more floors, it often happens that horizontal cracks form in the exterior wall, along the line where the floor and the wall meet. Such cracks can spread in the thickness of the wall to the facade and constitute a zone of infiltration of water harmful to the building.

L'invention propose de remédier à ces inconvénients en disposant horizontalement une baguette creuse d'une forme particulière le long de la fissure.The invention proposes to remedy these drawbacks by horizontally arranging a hollow rod of a particular shape along the crack.

Une telle baguette posée présente vue en coupe un fond vertical dont la partie arrière est coiffée par un coulisseau. Ce fond est avantageusement positionné légèrement au-dessus de la ligne de fissuration à protéger. La paroi supérieure de la baguette est légèrement inclinée vers le haut par rapport à l'horizontale, et son extrémité arase la surface extérieure de l'enduit. La paroi inférieure de la baguette est plus fortement inclinée par rapport à l'horizontale, c'est-à-dire qu'elle présente, par rapport à la verticale, un profil en pente douce dirigée vers le bas. Cette paroi inférieure se termine par un tablier vertical recouvrant l'enduit. Ce tablier recouvre donc la partie inférieure du coulisseau noyé dans l'enduit et s'étend vers le bas, au-delà de la ligne de fissuration. A l'extrémité de ce tablier, l'enduit est disposé de façon arasante et de niveau.Such a laid strip has a sectional view of a vertical bottom, the rear part of which is capped by a slide. This bottom is advantageously positioned slightly above the crack line to be protected. The upper wall of the strip is slightly inclined upwards relative to the horizontal, and its end level the outside surface of the plaster. The lower wall of the rod is more strongly inclined relative to the horizontal, that is to say that it has, relative to the vertical, a gently sloping profile directed downwards. This lower wall ends with a vertical deck covering the plaster. This deck therefore covers the lower part of the slide embedded in the coating and extends downwards, beyond the crack line. At the end of this deck, the plaster is leveled and level.

Finalement le tablier recouvre la ligne de fissuration et l'enduit est disposé le long du mur en une couche généralement continue, éventuellement localement interrompue au voisinage du coulisseau dans la zone d'ancrage du dispositif de fixation, si celui-ci est ancré dans le mur. Cette zone d'interruption a une étendue extrêmement faible, même en regard de l'étendue du coulisseau.Finally the deck covers the crack line and the plaster is placed along the wall in a generally continuous layer, possibly locally interrupted in the vicinity of the slide in the anchoring zone of the fixing device, if it is anchored in the Wall. This interruption zone has an extremely small extent, even opposite the extent of the slide.

Le profilé suivant ce mode de réalisation sert à la fois de rejet d'eau et de protège-fissure.The profile according to this embodiment serves both as a water discharge and as a crack guard.

Chaque coulisseau est finalement noyé dans l'enduit et est avantageusement doté de parties protubérantes dépassant de la partie médiane, pouvant, par exemple être formées sur des nervures et dont la forme et la disposition leur permet de renforcer la prise et l'ancrage du coulisseau dans l'enduit. Ces parties protubérantes peuvent être placées sur la face du coulisseau dirigée vers le mur.Each slider is finally embedded in the coating and is advantageously provided with protruding parts protruding from the middle part, which can, for example, be formed on ribs and whose shape and arrangement allows them to strengthen the grip and anchoring of the slider in the coating. These protruding parts can be placed on the face of the slide facing the wall.

Le guidage en translation de la baguette dans le coulisseau peut être assuré par deux rainures parallèles recevant les bords latéraux de la face arrière de la baguette. Ces rainures sont avantageusement formées dans deux nervures parallèles dépassant de la bande médiane du coulisseau.The guiding in translation of the rod in the slide can be ensured by two parallel grooves receiving the lateral edges of the rear face of the rod. These grooves are advantageously formed in two parallel ribs protruding from the middle band of the slide.

Suivant l'épaisseur désirée de l'enduit appliqué sur le mur, il est parfois nécessaire de disposer d'un système à joint réglable en épaisseur. Pour ce faire, il est utile que les coulisseaux soient emboîtables. Ainsi, les nervures formées sur une des faces peuvent présenter des contours adaptés au profil intérieur des nervures formées sur l'autre face et peuvent par exemple s'insérer et être guidées en translation dans des rainures formées sur ces nervures.Depending on the desired thickness of the coating applied to the wall, it is sometimes necessary to have a thickness adjustable joint system. To do this, it is useful that the slides are nestable. Thus, the ribs formed on one of the faces can have contours adapted to the internal profile of the ribs formed on the other face and can for example be inserted and be guided in translation in grooves formed on these ribs.

Il est également possible de doter une des faces, de deux rainures dont l'écartement permet le guidage de baguettes d'une largeur déterminée et de doter l'autre face, de deux rainures dont l'écartement est plus important afin de guider des baguettes plus larges.It is also possible to provide one of the faces with two grooves, the spacing of which allows the guiding of rods of a determined width, and to provide the other face, with two grooves, the spacing of which is greater in order to guide the rods. wider.

Sur la face tournée vers le mur et qui n'est donc pas utilisée pour le guidage de la baguette creuse, les rainures peuvent contribuer à former les profils d'ancrage.On the side facing the wall, which is therefore not used for guiding the hollow rod, the grooves can help to form the anchoring profiles.

Outre la partie médiane, le coulisseau peut comporter deux parties latérales généralement planes qui augmentent la surface de prise dans l'enduit.In addition to the middle part, the slider may have two generally flat side parts which increase the grip surface in the plaster.

Dans le cas d'un système à joint servant de protège-fissures, on peut positionner le coulisseau de manière que la fissure soit alignée avec le milieu de la partie latérale du coulisseau s'étendant vers le bas. Ainsi, on est certain que le tablier de la baguette creuse utilisée recouvre la ligne de fissuration.In the case of a joint system serving as crack protectors, the slide can be positioned so that the crack is aligned with the middle of the lateral part of the slide extending downwards. Thus, one is certain that the apron of the hollow rod used covers the line of cracking.

Des ouvertures suffisantes pour permettre le passage de l'enduit peuvent être réparties sur la surface du coulisseau de façon à améliorer la répartition de l'enduit lors de la pose.Sufficient openings to allow the plaster to pass can be distributed over the surface of the slider so as to improve the distribution of the plaster during installation.

Le système à joint est avantageusement fabriqué en matière plastique, PVC ou autres matériaux équivalents.The joint system is advantageously made of plastic, PVC or other equivalent materials.

Divers autres caractéristiques et avantages ressortent de la description détaillée qui suit.Various other features and advantages will emerge from the detailed description which follows.

  • FIG. 1 is a perspective view of the installed joint system,
  • FIG. 2 is a sectional view of a preferred embodiment,

  • FIG. 4 represents, seen from the side, two sliders nested in superposition,
  • FIG. 5 is a perspective view of a slide,
  • Figure 6 schematically shows three successive phases of a preferred method of fixing the joint system.

Comme on peut le voir sur les figures, notamment sur la figure 1, le système à joint 1 est posé sur un mur 2 couvert d'enduit 3.As can be seen in the figures, in particular in FIG. 1, the joint system 1 is placed on a wall 2 covered with plaster 3.

Le mur peut être une façade ou un mur quelconque extérieur ou intérieur, contre lequel une couche d'enduit est appliquée.The wall can be any facade or any exterior or interior wall, against which a layer of plaster is applied.

Le système à joint 1 comporte une baguette creuse ouverte décorative 4, posée dans l'enduit 3, dont elle affleure la surface extérieure par l'extrémité 5 de ses bords ; le système à joint est utilisé pour la décoration de l'enduit.The joint system 1 comprises a decorative open hollow rod 4, placed in the coating 3, of which it is flush with the outer surface by the end 5 of its edges; the joint system is used for the decoration of the plaster.

La baguette creuse est ouverte du côté opposé au mur.The hollow rod is open on the side opposite the wall.

Le système à joint peut être posé horizontalement, comme le montre la figure 1 ou dans un sens quelconque, de manière à réaliser des motifs de décoration.The joint system can be installed horizontally, as shown in Figure 1 or in any direction, so as to produce decoration patterns.

Un dispositif de fixation ancré dans le mur suivant un mode préféré de réalisation est visible, sous la référence 6, sur la figure 2 et assure une liaison entre le mur et la baguette.A fixing device anchored in the wall according to a preferred embodiment is visible, under the reference 6, in Figure 2 and provides a connection between the wall and the strip.

La baguette est montée coulissante par rapport au dispositif de fixation et parallèlement au mur.The strip is slidably mounted relative to the fixing device and parallel to the wall.

Pour faciliter la compréhension, une partie de l'enduit est arrachée sur la figure 1 afin de montrer le mur 2 et un coulisseau 7 noyé dans l'enduit.To facilitate understanding, part of the coating is torn off in Figure 1 to show the wall 2 and a slide 7 embedded in the coating.

Ce coulisseau 7 représenté plus en détail sur les figures 2 à 5, coiffe la partie arrière de la baguette creuse 4 et guide librement cette dernière en translation.This slide 7 shown in more detail in Figures 2 to 5, covers the rear part of the hollow rod 4 and freely guides the latter in translation.

Il est possible de prévoir plusieurs coulisseaux répartis sur la longueur de la baguette. Les coulisseaux sont alors avantageusement écartés de 40 à 50 cm les uns des autres. Le dispositif de fixation supporte les coulisseaux, au moins un par un et les maintient dans l'enduit, mais écartés du mur d'une distance prédéterminée.It is possible to provide several slides distributed over the length of the rod. The slides are then advantageously spaced 40 to 50 cm from each other. The fixing device supports the slides, at least one by one and keeps them in the plaster, but spaced from the wall by a predetermined distance.

Sur la figure 2, une baguette creuse 4 suivant un mode particulier de réalisation est montée sur un coulisseau 7.In FIG. 2, a hollow rod 4 according to a particular embodiment is mounted on a slide 7.

Cette baguette présente une face arrière dont les bords latéraux 8 sont insérés dans des rainures 9 du coulisseau.This rod has a rear face, the lateral edges 8 of which are inserted into grooves 9 of the slide.

La baguette creuse est ouverte vers l'extérieur et montre un fond 10 bordé de deux parois obliques 11. Ces parois obliques se terminent par un profil en forme de nez 12, replié vers l'intérieur de l'enduit, c'est-à-dire vers le mur et formant une gorge intérieure tournée vers le mur. La distance a entre l'extrémité de ces nez et la partie la plus proche du coulisseau est suffisante pour permettre le passage de l'enduit. La surface extérieure de l'enduit 3 affleure la partie des parois obliques 11 située à la plus grande distance du fond 10 de la baguette 4.The hollow rod is open towards the outside and shows a bottom 10 bordered by two oblique walls 11. These oblique walls end in a nose-shaped profile 12, folded towards the inside of the coating, that is to say - say towards the wall and forming an interior groove facing the wall. The distance a between the end of these noses and the part closest to the slide is sufficient to allow the coating to pass. The outer surface of the coating 3 is flush with the part of the oblique walls 11 located at the greatest distance from the bottom 10 of the strip 4.

Une autre forme de réalisation de la baguette creuse est illustrée par la figure 3.Another embodiment of the hollow rod is illustrated in FIG. 3.

A l'instar de la précédente, la baguette creuse 13 présentée est ouverte vers l'extérieur et montre une face arrière dont les bords latéraux 14 sont insérés dans des rainures 9 du coulisseau. Cette baguette est destinée à être disposée horizontalement le long d'un mur et présente un fond 15 vertical parallèle au mur, bordé de deux parois. La paroi supérieure 16 est légèrement inclinée par rapport à l'horizontale et dirigée vers le haut. La surface extérieure de l'enduit 3 affleure l'extrémité de cette paroi.Like the previous one, the hollow rod 13 presented is open towards the outside and shows a rear face, the lateral edges 14 of which are inserted into grooves 9 of the slide. This rod is intended to be arranged horizontally along a wall and has a vertical bottom 15 parallel to the wall, bordered by two walls. The upper wall 16 is slightly inclined relative to the horizontal and directed upwards. The outer surface of the coating 3 is flush with the end of this wall.

La paroi inférieure 17 montre une partie plus fortement inclinée par rapport à l'horizontale et dirigée vers le bas et dont la pente par rapport au fond de la baguette 13 est donc plus faible que celle de l'autre paroi. Cette paroi 17 se termine par un tablier plan vertical 18 s'étendant sur l'enduit, au-delà du coulisseau et au delà de la ligne de fissuration 19. Ce tablier est ainsi parallèle au mur et l'épaisseur d'enduit est ajustée à niveau à son extrémité.The lower wall 17 shows a part which is more inclined with respect to the horizontal and directed downwards and whose slope relative to the bottom of the strip 13 is therefore lower than that of the other wall. This wall 17 ends with a vertical plane deck 18 extending over the plaster, beyond the slide and beyond the crack line 19. This deck is thus parallel to the wall and the thickness of plaster is adjusted. level at its end.

La figure 2 permet de détailler le dispositif de fixation 6.FIG. 2 makes it possible to detail the fixing device 6.

Cette figure montre que le coulisseau 7 comporte une partie médiane plane 20, dans laquelle une ouverture 21 est pratiquée afin de permettre l'engagement du dispositif de fixation 6.This figure shows that the slide 7 has a flat central part 20, in which an opening 21 is made in order to allow the engagement of the fixing device 6.

Le dispositif de fixation 6 comprend une partie nervurée 22 destinée à être ancrée dans le mur 2. Les nervures 23 formées sur cette partie servent à renforcer l'ancrage dans le mur. Ce dispositif 6 comporte également une partie d'écartement 24, raccordée par un épaulement 25 à la partie nervurée 22 et une bride de retenue 26 solidaire de l'extrémité libre de la partie d'écartement.The fixing device 6 comprises a ribbed part 22 intended to be anchored in the wall 2. The ribs 23 formed on this part serve to reinforce the anchoring in the wall. This device 6 also includes a spacer part 24, connected by a shoulder 25 to the ribbed part 22 and a retaining flange 26 secured to the free end of the spacer part.

Le diamètre de la partie d'écartement 24 est supérieur à celui de la partie nervurée 22 et tel que l'épaulement 25 vienne en butée contre le mur.2 Ce diamètre est également adapté au passage en force dans l'ouverture 21 du coulisseau.The diameter of the spacing part 24 is greater than that of the ribbed part 22 and such that the shoulder 25 abuts against the wall. 2 This diameter is also adapted to the passage in force in the opening 21 of the slide.

La bride de retenue 26 porte contre le bord de l'ouverture 21 du côté du coulisseau tourné vers la baguette creuse. Afin que la translation de la baguette sur le coulisseau ne soit pas gênée par cette bride de retenue, deux épaulements 27 sont pratiqués sur la partie médiane du coulisseau, de manière à assurer un espace adapté à l'épaisseur de la bride 26. Il est avantageux que cet espace soit tel que la distance entre la partie arrière de la baguette creuse et la bride soit minimale, de façon à limiter ou à empêcher un mouvement de recul du dispositif de fixation lors de l'ancrage dans le mur.The retaining flange 26 bears against the edge of the opening 21 on the side of the slide facing the hollow rod. So that the translation of the rod on the slide is not hampered by this retaining flange, two shoulders 27 are formed on the middle part of the slide, so as to provide a space adapted to the thickness of the flange 26. It is advantageous that this space is such that the distance between the rear part of the hollow strip and the flange is minimum, so as to limit or prevent a backward movement of the fixing device when anchoring in the wall.

L'interstice résiduel entre les épaulements 27, la bride 26 et la partie arrière de la baguette peut être rempli d'enduit.The residual gap between the shoulders 27, the flange 26 and the rear part of the strip can be filled with plaster.

Sur cette figure, les distances b, c et d indiquent des minima théoriques d'épaisseur. La distance b, entre le mur 2 et la partie arrière de la baguette creuse 4 correspond de préférence à une épaisseur d'enduit au moins égale à 8 mm. Le dispositif de fixation maintient le coulisseau dans l'enduit écarté du mur d'une distance c prédéterminée, au moins égale à 2mm. L'épaisseur d totale d'enduit, c'est-à-dire la distance entre le mur 2 et la surface extérieure de l'enduit est au moins égale à 14 mm.In this figure, the distances b, c and d indicate theoretical minima in thickness. The distance b between the wall 2 and the rear part of the hollow strip 4 preferably corresponds to a coating thickness at least equal to 8 mm. The fixing device keeps the slide in the plaster spaced from the wall by a predetermined distance c, at least equal to 2mm. The total thickness d of the plaster, that is to say the distance between the wall 2 and the exterior surface of the plaster is at least equal to 14 mm.

Sur la figure 3, le dispositif de fixation assurant la liaison entre la baguette creuse et le mur n'est pas ancré dans le mur.In FIG. 3, the fixing device ensuring the connection between the hollow rod and the wall is not anchored in the wall.

Ce dispositif de fixation est par exemple constitué de ciment colle ou de mastic colle 28 appliqué contre le mur sur une épaisseur suffisante pour maintenir le coulisseau fixé dans l'enduit, mais écarté du mur d'une distance prédéterminée. Cet écartement est assuré par une cale ou une jauge amovible non représentée.This fixing device is for example made up of adhesive cement or adhesive mastic 28 applied against the wall over a thickness sufficient to keep the slide fixed in the coating, but spaced from the wall by a predetermined distance. This spacing is provided by a shim or a removable gauge not shown.

La baguette suivant un mode quelconque de réalisation est montée initialement coulissante par rapport à ce dispositif de fixation.The rod according to any embodiment is initially slidably mounted relative to this fixing device.

Les figures 2 à 5 montrent que le coulisseau 7 est muni de profils d'ancrage 29 assurant une meilleure prise dans l'enduit. Ces profils d'ancrage sont formés sur la face du coulisseau tournée vers le mur, tandis que deux rainures 9 sont formées sur l'autre face et guident la baguette creuse 4 en translation.Figures 2 to 5 show that the slide 7 is provided with anchoring profiles 29 ensuring a better grip in the coating. These anchoring profiles are formed on the face of the slide facing the wall, while two grooves 9 are formed on the other face and guide the hollow rod 4 in translation.

Suivant un mode préféré de réalisation, comme les références de la figure 4 l'indiquent, chacune des deux faces du coulisseau est dotée de deux épaulements 27, 30, de profils d'ancrage 29, 31 et de deux rainures de guidage 9, 32, de sorte que le coulisseau est réversible. Cette conformation présente un intérêt particulier dans le cas où les écartements des rainures 9, 32 de chaque face sont différents, de sorte que le coulisseau est adapté au guidage de deux baguettes de largeurs différentes.According to a preferred embodiment, as the references in FIG. 4 indicate, each of the two faces of the slide is provided with two shoulders 27, 30, anchoring profiles 29, 31 and two guide grooves 9, 32, so that the slide is reversible. This conformation is of particular interest in the case where the spacings of the grooves 9, 32 of each face are different, so that the slide is suitable for guiding two rods of different widths.

La figure 4 représente deux coulisseaux emboîtés en superposition. En effet, suivant un mode de réalisation avantageux, chacune des deux faces du coulisseau comporte deux nervures parallèles bordant la partie médiane 20, dans lequelles sont formées deux rainures 9, 32 et deux profils d'ancrage 29, 31. Chaque nervure de la face dont les rainures 9 ont l'écartement e le moins large présente un profil extérieur en forme de nez 33. La profondeur et l'écartement f des rainures 32 pratiquées dans les nervures de l'autre face du coulisseau sont telles que la base des nez 33 chevauche en projection au moins partiellement la base des rainures 32 et que, également en projection, la partie supérieure de ces nez 33 chevauche au moins partiellement la partie supérieure des rainures 32. En outre, la hauteur des rainures 32 est sensiblement égale à la hauteur des nez 33. Ainsi le coulisseau est emboîtable en superposition avec un coulisseau identique. Cette possibilité de superposer deux ou plusieurs coulisseaux permet d'adapter le système à joint à une épaisseur plus importante d'enduit.FIG. 4 shows two sliders nested in superposition. In fact, according to an advantageous embodiment, each of the two faces of the slide comprises two parallel ribs bordering the middle part 20, in which two grooves 9, 32 and two anchoring profiles 29, 31 are formed. Each rib of the face whose grooves 9 have the smallest spacing e has an external profile in the form of a nose 33. The depth and spacing f of the grooves 32 made in the ribs on the other face of the slide are such that the base of the noses 33 overlaps in projection at least partially the base of the grooves 32 and that, also in projection, the upper part of these noses 33 overlaps at least partially the upper part of the grooves 32. In addition, the height of the grooves 32 is substantially equal to the height of the noses 33. Thus the slide is nestable in superposition with an identical slide. This possibility of superimposing two or more slides makes it possible to adapt the joint system to a greater thickness of plaster.

Suivant un mode particulier de réalisation, le coulisseau 7 peut être muni de deux ailes 34 s'étendant latéralement dans le plan de la bande médiane 20, la surface du coulisseau est ainsi augmentée, ce qui améliore la prise et la solidarisation avec l'enduit.According to a particular embodiment, the slide 7 can be provided with two wings 34 extending laterally in the plane of the median strip 20, the surface of the slide is thus increased, which improves the grip and the connection with the coating. .

La figure 5 est une vue en perspective du coulisseau et montre que des ouvertures 35 peuvent être pratiquées sur la partie plane du coulisseau comprenant la partie médiane et les ailes latérales ; leur dimension doit être suffisante pour laisser passer l'enduit, de sorte que ces ouvertures 35 servent d'abord lors de la pose à réguler l'épaisseur d'enduit entre le mur et le coulisseau, puis à assurer une meilleure prise du coulisseau dans l'enduit posé.Figure 5 is a perspective view of the slider and shows that openings 35 can be made on the flat part of the slider comprising the middle part and the lateral wings; their size must be sufficient to allow the plaster to pass through, so that these openings 35 serve firstly during installation to regulate the thickness of plaster between the wall and the slider, then to ensure better grip of the slider in the applied coating.

Ces ouvertures sont indépendantes de l'ouverture 21 éventuellement pratiquée dans la partie médiane du coulisseau pour permettre le passage de l'organe de fixation 6.These openings are independent of the opening 21 possibly made in the middle part of the slide to allow the passage of the fixing member 6.

La figure 6 montre schématiquement trois phases d'un procédé préféré de fixation du système à joint comportant, suivant un mode préféré de réalisation, un dispositif de fixation 6, ancré dans le mur.FIG. 6 schematically shows three phases of a preferred method of fixing the joint system comprising, according to a preferred embodiment, a fixing device 6, anchored in the wall.

Dans un premier temps, après le forage d'au moins un trou dans le mur 2, puis le montage du dispositif de fixation 6 puis de la baguette creuse 4 sur au moins deux coulisseaux 7, l'ensemble est présenté et mis en position avec un enfoncement partiel du dispositif de fixation dans le trou pratiqué dans le mur.Firstly, after drilling at least one hole in the wall 2, then mounting the fixing device 6 and then the hollow rod 4 on at least two slides 7, the assembly is presented and placed in position with partial insertion of the fixing device into the hole in the wall.

Une première couche 3a d'enduit est alors projetée sur le mur 2, puis il est procédé à l'enfoncement complet de l'ensemble dans la première couche d'enduit 7, jusqu'à ce que l'épaulement de la partie d'écartement bute contre le mur, et au réglage de l'épaisseur et de l'alignement. Les ouvertures 35 de la partie plane du coulisseau permettent à l'enduit de se répartir convenablement lors de cette phase du procédé de fixation.A first layer 3a of plaster is then projected onto the wall 2, then the assembly is completely inserted into the first layer of plaster 7, until the shoulder of the part of spacing abuts against the wall, and to the adjustment of the thickness and alignment. The openings 35 in the flat part of the slide allow the plaster to be distributed properly during this phase of the fixing process.

Enfin, une deuxième couche d'enduit est projetée, noyant les coulisseaux et arasant les bords de la baguette creuse.Finally, a second layer of plaster is sprayed, drowning the slides and leveling the edges of the hollow rod.

Ce procédé est, bien sûr, utilisable lorsque le système à joint comporte la baguette creuse 13 représentée sur la figure 3, ou une autre baguette creuse adaptable sur le coulisseau 7.This method is, of course, usable when the joint system comprises the hollow rod 13 shown in FIG. 3, or another hollow rod adaptable to the slide 7.

Lorsque le dispositif de fixation est constitué de ciment colle ou de mastic colle, on peut utiliser un procédé de fixation suivant lequel la baguette creuse 1 ou 13, ou une autre baguette convenable, est montée sur au moins deux coulisseaux 7, du ciment colle ou du mastic colle est projeté sur les zones du mur 2 destinées à recevoir les coulisseaux 7, puis l'ensemble constitué de la baguette creuse et des coulisseaux est disposé de façon que le ciment colle ou le mastic colle recouvre la partie arrière des coulisseaux, il est ensuite procédé au réglage de l'épaisseur à l'aide d'une cale ou d'une jauge amovible, enfin, après séchage du ciment colle ou du mastic colle, une couche finale d'enduit est projetée de façon à noyer les coulisseaux et à araser les bords extrêmes de la baguette creuse utilisée.When the fixing device is made of adhesive cement or adhesive mastic, one can use a fixing method according to which the hollow rod 1 or 13, or another suitable rod, is mounted on at least two slides 7, adhesive cement or adhesive sealant is sprayed onto the areas of the wall 2 intended to receive the slides 7, then the assembly consisting of the hollow rod and the slides is arranged so that the adhesive cement or the adhesive sealant covers the rear part of the slides, it the thickness is then adjusted using a shim or a removable gauge, finally, after drying of the adhesive cement or the adhesive mastic, a final layer of coating is sprayed so as to drown the slides and to level the extreme edges of the hollow rod used.
