Description

L'invention se rapporte principalement à des plaques pour plafonds suspendus et leur procédé de mise en oeuvre.The invention relates mainly to plates for suspended ceilings and their implementation process.

Il est connu de réaliser des faux plafonds dits plafonds en staff, en utilisant des plaques de plâtre, généralement armées de fibres, telles que des fibres de verre. Ces plaques de plâtre sont fixées au plafond. L'ajustage n'étant pas parfait, il apparaît frequemment des fissures au niveau de jonction de deux plaques. Ces fissures se propagent dans la couche de peinture et finissent par donner un plafond inesthétique.It is known to produce false ceilings called staff ceilings, using plasterboard, generally reinforced with fibers, such as glass fibers. These plasterboards are fixed to the ceiling. Since the fit is not perfect, cracks frequently appear at the junction of two plates. These cracks propagate in the paint layer and eventually give an unsightly ceiling.

Les plaques, selon la présente invention, remédient à l'inconvénient des plaques de types connus en utilisant le collage de plaques successives, par exemple avec une colle pour carreaux de plâtre.The plates according to the present invention overcome the drawback of plates of known types by using the bonding of successive plates, for example with an adhesive for plaster tiles.

Le collage de plaques pour faux plafonds semblait impossible du fait que la surépaisseur de colle entre les plaques provoque des décalages en hauteur entre celles-ci, ce qui ne permet pas d'obtenir un plafond plan.The gluing of plates for false ceilings seemed impossible because the excess thickness of glue between the plates causes height shifts between them, which does not allow a flat ceiling to be obtained.

Les plaques selon la présente invention comportent des moyens pour réaliser des mises à niveau. Ces moyens ne sont pas perturbés par la présence de la colle. Ainsi, on obtient un niveau constant et donc un plafond plat.The plates according to the present invention include means for performing upgrades. These means are not disturbed by the presence of the adhesive. Thus, we obtain a constant level and therefore a flat ceiling.

Avantageusement, les moyens de mise à niveau des plaques selon la présente invention, sont réalisés sous forme d'espaceurs créant un espace entre les plaques susceptible d'être rempli par la colle. Il suffit qu'il n'y ait pas de colle au niveau des espaceurs pour qu'ils assurent la mise à niveau précise des plaques selon la présente invention.Advantageously, the means for leveling the plates according to the present invention are produced in the form of spacers creating a space between the plates capable of being filled with adhesive. It suffices that there is no glue at the spacers so that they ensure the precise leveling of the plates according to the present invention.

Avantageusement, les espaceurs d'une plaque ont une surface de contact négligeable avec la plaque adjacente. Dans ce cas, la plaque comportant ces espaceurs, ou mise en place sur les espaceurs d'une plaque adjacente, chassera par son poids lors de sa mise en place la colle qui risquerait de perturber la mise à niveau de deux plaques successives lors du collage.Advantageously, the spacers of a plate have a negligible contact surface with the adjacent plate. In this case, the plate comprising these spacers, or placed on the spacers of an adjacent plate, will expel by its weight when it is put in place the adhesive which would risk disturbing the leveling of two successive plates during bonding. .

Avantageusement, les espaceurs ont une forme d'une partie de cylindre. Cette forme présente une grande facilité de réalisation et une bonne résistance à l'usure et aux chocs. Cette forme permet en outre de repousser progressivement et complètement la colle lors de la mise en place de la plaque.Advantageously, the spacers have the shape of a cylinder part. This form has great ease of production and good resistance to wear and impact. This shape also makes it possible to gradually and completely repel the glue when the plate is put in place.

Avantageusement, deux plaques successives sont réunies par une feuillure. Avantageusement, les espaceurs sont placés dans la partie supérieure de la feuillure, en étant dirigés vers le bas.Advantageously, two successive plates are joined by a rebate. Advantageously, the spacers are placed in the upper part of the rebate, while being directed downwards.

On entend par feuillure, une jonction comportant une corniche ou une saillie inférieure et une corniche ou une saillie supérieure reposant sur la corniche ou sur la faillie inférieure. Bien que cela ne soit pas impératif, il est avantageux d'utiliser des corniches horizontales. Il est très important qu'un déplacement horizontal limité d'une plaque par rapport à une autre ne provoque pas de variation de la hauteur relative de ces deux plaques. Par exemple, la corniche inférieure (respectivement supérieure) comporte une saillie de surface de contact négligeable, venant en contact avec la corniche supérieure (respectivement inférieure) horizontale.Rebate means a junction comprising a cornice or a lower projection and a cornice or an upper projection resting on the cornice or on the lower bank. Although it is not imperative, it is advantageous to use horizontal cornices. It is very important that a limited horizontal movement of one plate with respect to another does not cause the relative height of these two plates to vary. For example, the lower (respectively upper) cornice has a negligible contact surface projection, coming into contact with the upper (respectively lower) horizontal cornice.

L'invention a principalement pour objet une plaque pour plafond suspendu comportant un fond et un raccord en forme de feillure destinée à être collée par assemblage avec une plaque adjacente, caractérisée par le fait que ledit raccord en forme de feuillure comporte des moyens de mise à niveau de deux plaques successives indépendamment d'un écart éventuel de deux plaques et de la présence de la colle.The main object of the invention is a plate for a suspended ceiling comprising a bottom and a groove-shaped connector intended to be glued by assembly with an adjacent plate, characterized in that said rebate-shaped connector comprises means for setting level of two successive plates independently of a possible deviation of two plates and the presence of the glue.

L'invention a également pour objet une plaque, caractérisée par le fait que les moyens de mise à niveau comportent des espaceurs placés dans les parties horizontales de la feuillure destinés à laisser un espace à la colle entre les deux plaques, ces espaceurs ayant une surface d'extrémité suffisamment limitée pour que le poids de la plaque lors de sa mise en place chasse la colle au niveau du contact de l'espaceur avec la plaque adjacente.The invention also relates to a plate, characterized in that the leveling means comprise spacers placed in the horizontal parts of the rebate intended to leave a space for the adhesive between the two plates, these spacers having a surface end enough limited so that the weight of the plate when it is put in place expels the glue at the contact of the spacer with the adjacent plate.

L'invention a également pour objet une plaque, caractérisée par le fait que les espaceurs sont disposés dans la partie supérieure de la feuillure.The invention also relates to a plate, characterized in that the spacers are arranged in the upper part of the rebate.

La plaque selon l'invention est de préférence constituée de plâtre, de préférence armé de fibres de verre.The plate according to the invention is preferably made of plaster, preferably reinforced with glass fibers.

L'invention a également pour objet une telle plaque, caractérisée par le fait qu'elle est réalisée d'un seul tenant par moulage.The invention also relates to such a plate, characterized in that it is made in one piece by molding.

L'invention a également pour objet une plaque, caractérisée par le fait que les espaceurs sont constitués par des parties de cylindre, dont une génératrice entre en contact avec la feuillure de la plaque avec laquelle elle doit être assemblée.The invention also relates to a plate, characterized in that the spacers are constituted by cylinder parts, one of which generatrix comes into contact with the rebate of the plate with which it is to be assembled.

L'invention a également pour objet une plaque, caractérisée par le fait qu'elle est rectangulaire et qu'elle comporte, sur deux côtés opposés des raccords d'assemblage, un de ces raccords étant équipé de moyens de mise à niveau.The invention also relates to a plate, characterized in that it is rectangular and that it has, on two sides opposite of the assembly fittings, one of these fittings being equipped with leveling means.

L'invention a également pour objet une plaque, caractérisée par le fait que son épaisseur au bord est égale à la somme de l'épaisseur des corniches inférieures, des corniches supérieures constituant la feuillure ainsi que de l'épaisseur des espaceurs.The invention also relates to a plate, characterized in that its thickness at the edge is equal to the sum of the thickness of the lower cornices, upper cornices constituting the rebate as well as the thickness of the spacers.

L'invention a également pour objet une plaque, caractérisée par le fait qu'elle comporte un fond dont l'épaisseur est inférieure à celle des raccords.The invention also relates to a plate, characterized in that it comprises a bottom whose thickness is less than that of the fittings.

L'invention a également pour objet un procédé de pose de faux plafonds, caractérisé par le fait qu'il comporte les étapes de:

  • mise en place de moyens de soutien;
  • mise en place, contre un mur de premières plaques, avec leur fixation au plafond;
  • collage de nouvelles plaques sur la plaque déjà fixée et la fixation de ces plaques au plafond;
  • réalisation de finitions.
The invention also relates to a method of installing false ceilings, characterized in that it comprises the steps of:
  • establishment of support means;
  • installation, against a wall of the first plates, with their attachment to the ceiling;
  • bonding of new plates on the plate already fixed and the fixing of these plates to the ceiling;

L'invention a également pour objet un procédé de pose de faux plafonds caractérisé par le fait qu'il comporte les étapes de:

  • enduction avec de la colle d'une corniche ou saillie inférieure de la plaque mise en place;
  • collage de la plaque suivante en faisant reposer les espaceurs de la corniche ou saillie supérieure sur la corniche inférieure de la plaque précédente enduite avec de la colle.
The invention also relates to a method of installing false ceilings characterized in that it comprises the steps of:
  • coating with glue a cornice or lower projection of the plate placed;
  • bonding of the next plate by resting the spacers of the cornice or upper projection on the lower cornice of the previous plate coated with glue.

L'invention a également pour objet un procédé de pose de faux plafonds, caractérisé par le fait qu'il comporte les étapes de:

  • mise en place d'une surface d'appui supérieure en un point de contact d'au moins deux plaques;
  • collage des plaques au niveau du raccord;

  • dépose de la surface d'appui inférieure après la solidification de la colle.
The invention also relates to a method of installing false ceilings, characterized in that it comprises the steps of:
  • placement of an upper bearing surface at a point of contact of at least two plates;
  • bonding of the plates at the connection;
  • establishment of a lower support surface at said point of contact of the plates to force the leveling of the plates;
  • removing the lower support surface after the glue has solidified.

L'invention sera mieux comprise au moyen de la description ci-après et des figures annexées données comme des exemples non limitatifs parmi lesquels:

  • la figure 1 est une vue en coupe d'un faux plafond comportant des plaques selon la présente invention;

The invention will be better understood by means of the description below and the appended figures given as nonlimiting examples among which:
  • Figure 1 is a sectional view of a false ceiling having plates according to the present invention;
  • Figure 2 is a sectional view of the joint of two successive plates;
  • Figure 3 is a perspective view of the end of a plate according to the present invention;
  • Figure 4 is a sectional view of an alternative embodiment of the junction of two successive plates;
  • Figure 5 is a sectional view of a junction of a plurality of plates using a plate leveling device.

Sur les figures 1 à 5 on a utilisé les mêmes références pour désigner les mêmes éléments.In FIGS. 1 to 5, the same references have been used to designate the same elements.

Sur la figure 1, on peut voir la pose d'un faux plafond composé d'une succession de plaques 2 selon la présente invention, avantageusement identiques. Le faux plafond est ancré dans le plafond 1. On part du mur 13. On fixe au plafond 1 la plaque 2 selon la présente invention, avec des polochons de scellement 5 constitués de manière conventionnelle de fibres, notamment de sisal enduites de plâtre. A ses extrémités, chaque plaque 2 comporte des raccords 20 permettant l'assemblage avec la plaque 2 suivante. Dans l'exemple illustré sur les figures, le raccord 20 permet de réaliser une feuillure. Un premier bord de la plaque 2 comporte une corniche ou saillie supérieure 4. Un second bord de la plaque 2 comporte une corniche ou saillie inférieure 3. Les corniches ou saillies 3 et 4 sont collées l'une sur l'autre avec une colle à carreaux de plâtre, par exemple celle vendue sous la marque "FUSCO". Des moyens particuliers selon la présente invention empêchent que l'épaisseur de la colle 6 ne fasse une surépaisseur au niveau du raccord 20. Des moyens de mise à niveau 61, 62, 63, 64 réalisent le contact entre les plaques 2 successives en laissant un espace pour la colle 6. Même au niveau de contact de deux plaques par les moyens de mise à niveau 61, 62, 63, 64, il n'existe pas de surépaisseur de colle 6. La jonction par collage est illustrée sur la figure 2. La colle 6 pénètre entre les deux plaques 2. Sur la plaque 2, de droite dans le cas illustré sur la figure 2, sont disposés des espaceurs 61 reposant sur la saillie inférieure 3 de la plaque 2 de gauche. On obtient ainsi un assemblage solide sans que la colle provoque une surépaisseur. Au niveau des espaceurs 61 il n'y a pas de colle entre les deux plaques 2. Cela provient avantageusement du fait que la surface de contact de l'espaceur 61 avec la corniche ou saillie inférieure 3 est négligeable ou nulle. Ainsi, la pression exercée par le poids de la plaque 2 de droite chasse la colle 6 au niveau de l'espaceur 61.In Figure 1, we can see the installation of a false ceiling composed of a succession of plates 2 according to the present invention, advantageously identical. The false ceiling is anchored in the ceiling 1. We start from the wall 13. The plate 2 according to the present invention is fixed to the ceiling 1, with sealing bolsters 5 conventionally made of fibers, in particular sisal coated with plaster. At its ends, each plate 2 has connections 20 allowing assembly with the following plate 2. In the example illustrated in the figures, the connector 20 makes it possible to produce a rebate. A first edge of the plate 2 has a top cornice or protrusion 4. A second edge of the plate 2 has a bottom cornice or protrusion 3. The cornices or protrusions 3 and 4 are glued to each other with a glue plaster tiles, for example that sold under the brand "FUSCO". Particular means according to the present invention prevent the thickness of the glue 6 from making an additional thickness at the connection 20. Leveling means 61, 62, 63, 64 make contact between the successive plates 2 leaving a space for glue 6. Even at the level of contact of two plates by the leveling means 61, 62, 63, 64, there is no excess thickness of glue 6. The bonding joint is illustrated in FIG. 2 The glue 6 enters between the two plates 2. On the plate 2, on the right in the case illustrated in FIG. 2, are arranged spacers 61 resting on the lower projection 3 of the plate 2 on the left. A solid assembly is thus obtained without the glue causing excess thickness. At the spacers 61 there is no glue between the two plates 2. This advantageously comes from the fact that the contact surface of the spacer 61 with the cornice or lower projection 3 is negligible or zero. Thus, the pressure exerted by the weight of the right plate 2 drives the glue 6 away from the spacer 61.

Le fait de disposer des espaceurs 61, 62, 63, 64 sur la plaque supérieure est avantageux dans la mesure où, selon les habitudes existant sur les chantiers, la colle 6 sera déposée sur la plaque 2 de gauche, déjà en place. Ainsi on risque moins que la colle 6 ne sèche sur les espaceurs 61, 62, 63, 64. Toutefois, il est bien entendu que les plaques 2 comportant des espaceurs 61, 62, 63, 64 sur leur partie inférieure ne sortent pas du cadre de la présente invention.The fact of having spacers 61, 62, 63, 64 on the upper plate is advantageous insofar as, according to the habits existing on building sites, the glue 6 will be deposited on the plate 2 on the left, already in place. Thus there is less risk that the glue 6 dries on the spacers 61, 62, 63, 64. However, it is understood that the plates 2 having spacers 61, 62, 63, 64 on their lower part do not leave the frame of the present invention.

Sur la figure 3, on peut voir divers exemples d'espaceurs susceptibles d'être mis en oeuvre dans les plaques selon la présente invention. L'espaceur 61 de type semi-cylindrique présente l'avantage d'être facilement réalisable et de présenter une grande résistance. Il risque moins d'être endommagé durant le transport et les manipulations sur un chantier. Dans l'exemple de réalisation, l'espaceur 61 a une largeur de 9 mm et une épaisseur de 3 mm. Les espaceurs 61 sont par exemple distants de 146 mm.In Figure 3, we can see various examples of spacers that can be used in the plates according to the present invention. The spacer 61 of semi-cylindrical type has the advantage of being easily achievable and of exhibiting great resistance. It is less likely to be damaged during transport and handling on site. In the exemplary embodiment, the spacer 61 has a width of 9 mm and a thickness of 3 mm. The spacers 61 are for example 146 mm apart.

La présente invention n'est pas limitée à l'utilisation d'espaceurs ayant une forme semi-cylindrique. A titre d'exemples non limitatifs, on. a illustré des espaceurs coniques 63 et un espaceur de section triangulaire 62. L'invention n'est pas limitée à des espaceurs dont la surface est négligeable. Elle dépend notamment du poids des plaques 2 réalisées. Si le poids de la plaque est plus important, les espaceurs ayant une surface de contact supérieure, arrivent à chasser la colle au niveau du contact entre les deux plaques 2. On peut par exemple utiliser des espaceurs ayant une section trapézoïdale 64, éventuellement dont les bords sont arrondis, ou une section carrée, (non représenté sur la figure). Sur la figure 3 les quatre types d'espaceurs sont illustrés sur une plaque 2 unique. Il est bien entendu qu'il peut s'avérer avantageux d'utiliser un seul type d'espaceur par plaque 2 selon la présente invention. Dans l'exemple illustré sur la figure 3, la plaque 2 a une épaisseur D, la corniche 4 a une épaisseur d3, les espaceurs ont une épaisseur d1, la distance entre l'espaceur 61, 62, 63, 64 et le bord inférieur de la plaque est égale à d2. d2 est aussi égale à l'épaisseur de la corniche ou saillie inférieure 3 située sur l'autre extrémité de la plaque (non représenté sur la figure 3). La colle 6 doit remplir un espace d'une épaisseur égale à d1. D = d1 + d2 = d3, il n'existe aucune surépaisseur due à la colle au niveau du raccord 20 de deux plaques 2 selon la présente invention.The present invention is not limited to the use of spacers having a semi-cylindrical shape. By way of nonlimiting examples, we. illustrated conical spacers 63 and a triangular section spacer 62. The invention is not limited to spacers whose surface is negligible. It depends in particular on the weight of the plates 2 produced. If the weight of the plate is greater, the spacers having a greater contact surface, manage to expel the glue at the contact between the two plates 2. One can for example use spacers having a trapezoidal section 64, possibly the edges are rounded, or a square section, (not shown in the figure). In Figure 3 the four types of spacers are illustrated on a single plate 2. It is understood that it may prove advantageous to use a single type of spacer per plate 2 according to the present invention. In the example illustrated in FIG. 3, the plate 2 has a thickness D, the cornice 4 has a thickness d3, the spacers have a thickness d1, the distance between the spacer 61, 62, 63, 64 and the lower edge of the plate is equal to d2. d2 is also equal to the thickness of the cornice or lower projection 3 located on the other end of the plate (not shown in Figure 3). The glue 6 must fill a space with a thickness equal to d1. D = d1 + d2 = d3, there is no excess thickness due to the adhesive at the connection 20 of two plates 2 according to the present invention.

Avantageusement, les plaques 2 selon la présente invention comportent un fond 21 dont l'épaisseur est inférieure à l'épaisseur des raccords 20. Par exemple, l'épaisseur D au niveau des raccords 20 est égale à 22 mm et l'épaisseur d du fond 21 des plaques 2 selon la présente invention est égale à 10 mm.. Avantageusement, la plaque 2 selon la présente invention comporte des nervures, par exemple parallèles aux bords, d'épaisseur sensiblement égale à celle des raccords 20.Advantageously, the plates 2 according to the present invention comprise a bottom 21 the thickness of which is less than the thickness of the fittings 20. For example, the thickness D at the fittings 20 is equal to 22 mm and the thickness d of the bottom 21 of the plates 2 according to the present invention is equal to 10 mm. Advantageously, the plate 2 according to the present invention comprises ribs, for example parallel to the edges, of thickness substantially equal to that of the fittings 20.

Il est avantageux de disposer les raccords 20 sur les grandes longueurs des plaques selon la présente invention. Toutefois, les plaques 2 comportant des joints sur les quatre côtés ou sur les petites longueurs, ne sortent pas du cadre de la présente invention.It is advantageous to arrange the fittings 20 over the long lengths of the plates according to the present invention. However, the plates 2 having seals on the four sides or on the short lengths, do not depart from the scope of the present invention.

Sur la figure 4, on peut voir une variante de réalisation des plaques selon la présente invention.In Figure 4, we can see an alternative embodiment of the plates according to the present invention.

Dans la variante de la figure 4, la corniche inférieure 3 comporte un plan incliné dont la pente s'élève au fur et à mesure que l'on se rapproche de la plaque suivante.In the variant of FIG. 4, the lower cornice 3 comprises an inclined plane whose slope rises as one approaches the next plate.

Le point culminant 65 constitue une saillie sur laquelle prend appui, soit directement la corniche supérieure 4 de la plaque suivante, soit, comme illustré sur l'exemple de la figure 4 par l'intermédiaire d'un espaceur 61. La corniche supérieure 4 s'appuie uniquement sur le point 65. Ainsi, un déplacement relatif limité, en tout cas inférieur à la largeur de la corniche supérieure 4, ne compromet pas la mise à niveau relative de deux plaques 2 successives. De plus, la pente de la corniche inférieure 3 permet la constitution d'un espace 7 susceptible de recevoir la colle 6 sans former de surépaisseur.The highest point 65 constitutes a projection on which is supported, either directly the upper cornice 4 of the following plate, or, as illustrated in the example of FIG. 4 via a spacer 61. The upper cornice 4 s 'presses only on point 65. Thus, a limited relative displacement, in any case less than the width of the upper ledge 4, does not compromise the relative leveling of two successive plates 2. In addition, the slope of the lower cornice 3 allows the constitution of a space 7 capable of receiving the glue 6 without forming any additional thickness.

La solidarisation des plaques 2 peut encore améliorer en créant un espace 7 supplémentaire pour la colle 6.The joining of the plates 2 can further improve by creating an additional space 7 for the glue 6.

Dans l'exemple illustré, dans la paroi verticale du raccord 20 on a formé des espaces en queue d'aronde 7. Les espaces 7 sont remplis de colle au moment de la pose des plaques 2. Ils améliorent la tenue du faux plafond.In the example illustrated, in the vertical wall of the connector 20, dovetail spaces 7 have been formed. The spaces 7 are filled with glue when the plates are installed 2. They improve the strength of the false ceiling.

Avantageusement, l'espace 7 en forme de queue d'aronde réalisé horizontalement effectue le tour de chaque plaque 2.Advantageously, the space 7 in the form of a dovetail formed horizontally circles each plate 2.

Une variante de réalisation non représentée des espaces en forme de queue d'arronde sont disposées verticalement au niveau de la jonction des plaques.An alternative embodiment, not shown, in the form of a dovetail is arranged vertically at the junction of the plates.

Les plaques selon la présente invertion permettent, si on ne commet pas une erreur grossière lors de la pose, d'obtenir un plafond plan et plat. Une erreur grossière peut provenir par exemple de l'utilisation d'une main d'oeuvre non qualifiée sur un chantier de construction, soit par la mise en oeuvre de plaques par un bricoleur.The plates according to this insertion allow, if one does not make a gross error during installation, to obtain a flat and flat ceiling. A gross error can come for example from the use of unskilled labor on a construction site, or by the implementation of plates by a handyman.

Sur la figure 5, on peut voir un dispositif pour forcer la mise à niveau d'une pluralité de plaques, même en présence d'une mise en oeuvre peu soignée. Le dispositif de la figure 5 comporte une surface d'appui supérieure 8 et une surface d'appui inférieure 9 assurant la mise à niveau d'une pluralité de plaques 2 pendant les opérations de pose. Quand les opérations de pose sont terminées, la colle qui s'est solidifiée assure la stabilité du plafond dans la position qui a été fixée par le dispositif de la figure 5.In FIG. 5, one can see a device for forcing the leveling of a plurality of plates, even in the presence of a careless implementation. The device of FIG. 5 comprises an upper bearing surface 8 and a lower bearing surface 9 ensuring the leveling of a plurality of plates 2 during the laying operations. When the laying operations are finished, the adhesive which has solidified ensures the stability of the ceiling in the position which has been fixed by the device of FIG. 5.

Le dispositif selon la présente invention comporte avantageusement une pièce en matière plastique comportant un plateau circulaire 8 et une tige filetée 18. Le plateau 8 et la tige 18 sont mis en place à la jonction d'une pluralité de plaques, avantageusement de trois plaques 2.The device according to the present invention advantageously comprises a plastic part comprising a circular plate 8 and a threaded rod 18. The plate 8 and the rod 18 are placed at the junction of a plurality of plates, advantageously three plates 2 .

La tige 18 est avantageusement disposée sur le côté des plaques 2 ne comportant pas de feuillure. Toutefois, les plaques 2 peuvent comporter une ouverture destinée à laisser passer la tige 18 sans sortir du cadre de la présente invention.The rod 18 is advantageously arranged on the side of the plates 2 not having a rebate. However, the plates 2 may have an opening intended to allow the rod 18 to pass without departing from the scope of the present invention.

Une fois les plaques encollées, on met en place un plateau inférieur 9 constituant la surface d'appui inférieure. Un écrou 10 est vissé sur la tige 18 de façon à appliquer le plateau 9 contre les plaques 2.Once the plates have been glued, a lower plate 9 is put in place constituting the lower support surface. A nut 10 is screwed onto the rod 18 so as to apply the plate 9 against the plates 2.

On réalise ainsi la mise à niveau forcée, au moins de la face inférieure de deux plaques 2. L'écrou 10 peut comporter des moyens de serrage intégrés comme par exemple des papillons.The forced leveling is thus carried out, at least on the underside of two plates 2. The nut 10 may have integrated tightening means such as, for example, butterflies.

Après solidification de la colle, on divisse l'écrou 10, on retire le plateau 9 et on procède à l'ablation de la partie de la tige 18 dépassant du faux plafond. Cette ablation est avantageusement facilitée par une faiblesse de la tige 18 à une longueur correspondant à l'épaisseur des plaques 2 au niveau de raccords 20.After the glue has solidified, the nut 10 is divided, the plate 9 is removed and the part of the rod 18 projecting from the false ceiling is removed. This ablation is advantageously facilitated by a weakness of the rod 18 at a length corresponding to the thickness of the plates 2 at the level of fittings 20.

Le plateau 9 est réutilisable sur un autre chantier tandis que le plateau 8 et une partie de la tige 18 restent en place dans le plafond.The plate 9 is reusable on another site while the plate 8 and part of the rod 18 remain in place in the ceiling.

Il est bien entendu que la réalisation des plateaux 8, 9 de la tige 18 et/ou de l'écrou 10 en métal ne sortent pas du cadre de la présente invention.It is understood that the production of the plates 8, 9 of the rod 18 and / or of the nut 10 made of metal does not depart from the scope of the present invention.

L'espace 7 en forme de queue d'aronde, la figure 4 ainsi que les dispositifs pour forcer la mise à niveau des plaques de la figure 5 peuvent être mis en oeuvre avec toute plaque en staff pour faux plafond et notamment avec la plaque illustrée sur les figures 1 à 3, ou avec des plaques de type connu, sans sortir du cadre de la présente invention.The space 7 in the form of a dovetail, FIG. 4 as well as the devices for forcing the leveling of the plates of FIG. 5 can be implemented with any staff plate for false ceilings and in particular with the plate illustrated. in Figures 1 to 3, or with plates of known type, without departing from the scope of the present invention.

L'invention s'applique principalement à la réalisation de plafonds et de faux plafonds.The invention mainly applies to the production of ceilings and false ceilings.
