Definitions
- the invention relates to a frame for prefabricated and removable partitions.
- the invention aims to simplify the mounting of these partitions by limiting to two the number of types of profiles necessary for the construction of the partitioning. It has for its object, for this purpose, a reinforcement system for partitioning in which the partition panels, the glazed panels, the frames, the glazing beads and the like cooperate, not only with the vertical and horizontal metallic profiles serving as reinforcement for the partitioning, but also with profiles of which the dorsal face has four wings delimiting three housings of which any one receives the head of a clip allowing its fixing to at least one of the two ends of the reinforcement profile, so that '' depending on its housing engaged with the clips, the same profile is used either as a symmetrical vertical joint cover on either side of a frame profile between two vertical panels or between a vertical panel and a frame, either as an asymmetrical horizontal joint cover in relation to the reinforcement profile between the floor or the ceiling and any panel or glazing bead.
- each profile serving as a joint cover comprises, on its dorsal face, four wings which have returns directed opposite one another, in order to form three slides extending over the entire length of the profile and one or the other of which serves as a housing for the heads of metal clips whose branches cooperate with an armature profile.
- a reinforcing profile consists of a rectilinear core comprising four longitudinal wings which are perpendicular thereto and which, thanks to returns provided at their ends, delimit on the two faces of the profile of the housings intended to cooperate with fasteners, the lateral longitudinal wings further having returns directed first outwards, then facing one another, to delimit housings with which the fastening clips cooperate profiles used as joint covers.
- Figure 1 shows a profile intended to serve as a joint cover.
- This profile consists of a core 1 having, on its dorsal face, four wings 2 which extend each by a return 3 directed opposite the neighboring wing; and each return 3 has an inclined plane 4.
- the profile thus formed has, on its rear face, three housings designated by 5 and in each of which the entry is facilitated by the cut sides 4.
- Each profile therefore has, on its rear face, three slides capable of receiving the heads of the clips 6; but it is important to note that each profile receives clips 6 only in one or the other of its slides 5.
- FIG. 2 shows a profile intended to serve as a reinforcement for partitioning.
- This profile consists of a core 7 of which four wings 8 are integral which extend perpendicularly on its two faces. These four wings, parallel to each other, end in returns 9 which delimit housings or slides 10 extending continuously over the entire length of the profile.
- the two lateral wings 8 have external returns 11 which delimit two other slides 12 extending over the entire length of the profile, on either side of its core 7. It is precisely these slides 12 which are intended to cooperate with the branches of the clips 6 to allow the fixing of the profiles 1 serving as joint covers on the profiles Z serving as reinforcement.
- FIGS. 3 to 5 illustrate some possible uses of the reinforcement profile 7 and the joint cover profile 1 respectively.
- FIG. 3 In the case of Figure 3 is shown in vertical section a solid partition placed between the floor 13 and the ceiling 14, this partition consisting of two external panels 15 made of any material, but placed on either side a central panel 16 of insulating material, for example glass wool, rock wool or basalt.
- two horizontal reinforcement sections Z are fixed respectively to the floor 13 and to the ceiling 14, this fixing being made for example by screwing.
- the partition consisting of elements 15 and 16 is fixed to two reinforcing profiles 7 by seals 17 made for example of neoprene and bearing, on the one hand, in the slides 10 of the members 7 and, on the other hand, in the space delimited by the outer panels 16 and by the inner panel 15.
- each of the four profiles 1, placed at the base and at the top of the partition, is in fact linked to the two reinforcing profiles 7 by clips 6 whose heads are supported in one of the lateral slides 5 of the profiles 1 and whose the legs are supported in the slides 12 of the profiles 7.
- the profiles 1 serve well, as shown in the drawing, as joint covers between the partition and the floor 13 or the ceiling 14; it should also be noted that a good junction is made between the profile 1 and the partition, as well as between the profile 1 and the profile 7, thanks to seals 18 provided on the two longitudinal wings 2 of the profile 1.
- FIG 4 illustrates the use of frame profiles 7 and joint cover profiles 1 in the case of a frame and a transom window seen in vertical section under a ceiling.
- 14 designates this ceiling
- 19 designates the transom
- 20 designates a door.
- a frame profile 7 is fixed by screwing under the ceiling 14 and another frame profile 7 is placed horizontally on the frame 21 of the frame with which the door 20 cooperates.
- Two glazing beads 22 and 23, made of metal or plastic material, are fixed to the two reinforcing profiles 7, and this by hooking to the returns 9 of their wings 8. These glazing beads are fitted with seals, respectively 24 and 25, on which the glass panel 19 of the transom rests, the fixing of which is carried out by two profiles 1.
- the profiles 1 are indeed subject to the profiles 7, while applying with tightness by their seals 18, respectively against a return of a wing profile 7 and against the glass panel 19, either against this panel and against the frame 21. It is in any case important to note that at the upper part, that is to say under the ceiling, the fixing clips are supported in the upper slide 5 of the profile 1, while at the connection between the glass panel 19 and the frame 21, the connection clips are supported in the middle slide 2 of the profile 1.
- Figure 5 finally illustrates, in horizontal section, the connection between two solid partitions and a door frame.
- the two solid partitions are constituted, as in the case of FIG. 1, by two external panels 15 and by an intermediate panel 16; the frame is designated by 27 and the door by 28.
- the two reinforcement sections 7 are placed vertically and orthogonally relative to each other, on either side of a rigid panel 29 crossed by a screw 30 which provides the connection between the two profiles.
- the connection between the solid partitions and the reinforcing profiles 7 is produced by seals 17 and by the profiles of joint cover 1; and it is clearly visible that these sections 1 are linked to the reinforcing sections 7 by clips 6 bearing on their middle slides 5 and that these sections 1 bear against the panels by means of their longitudinal joints 18.
- reinforcement sections 7 and joint cover sections 1 are not limited to the only cases which have been indicated above as examples; and the invention is not limited moreover to only the embodiments which have been indicated above, also by way of examples for these two types of profiles; on the contrary, it embraces all of its variant embodiments.

Description
L'invention a pour objet une armature pour cloisons préfabriquées et démontables.The invention relates to a frame for prefabricated and removable partitions.
Dans la construction immobilière, il est connu de réaliser des cloisonnements amovibles en matériau préfabriqué en utilisant comme éléments de base des profilés métalliques, généralement en aluminium, auxquels sont associés d'autres profilés servant de couvre-joint et assurant l'immobilisation simultanée des panneaux, des vitrages, des parcloses, des huisseries et autres éléments pouvant entrer dans la constitution d'un cloisonnement.In building construction, it is known to produce removable partitions in prefabricated material using as basic elements metal profiles, generally aluminum, with which are associated other profiles serving as joint cover and ensuring the simultaneous immobilization of the panels. , glazing, glazing beads, doorframes and other elements that can be used to create a partition.
L'invention vise à simplifier le montage de ces cloisonnements en limitant à deux le nombre des types de profilés nécessaires à la construction du cloisonnement. Elle a pour objet, à cet effet, un système d'armature pour cloisonnement dans lequel les panneaux de cloison, les panneaux vitrés, les huisseries, les parcloses et similaires coopèrent, non seulement avec les profilés métalliques verticaux et horizontaux servant d'armature au cloisonnement, mais aussi avec des profilés dont la face dorsale présente quatre ailes délimitant trois logements dont l'un quelconque reçoit la tête d'un clipspermettant sa fixation à au moins l'une des deux extrémités du profilé d'armature, de telle sorte qu'en fonction de son logement en prise avec le clips, le même profilé est utilisé soit comme couvre-joint vertical symétrique de part et d'autre d'un profilé d'armature entre deux panneaux verticaux ou entre un panneau vertical et une huisserie, soit comme couvre-joint horizontal dissymétrique par rapport au profilé d'armature entre le sol ou le plafond et un panneau quelconque ou une parclose.The invention aims to simplify the mounting of these partitions by limiting to two the number of types of profiles necessary for the construction of the partitioning. It has for its object, for this purpose, a reinforcement system for partitioning in which the partition panels, the glazed panels, the frames, the glazing beads and the like cooperate, not only with the vertical and horizontal metallic profiles serving as reinforcement for the partitioning, but also with profiles of which the dorsal face has four wings delimiting three housings of which any one receives the head of a clip allowing its fixing to at least one of the two ends of the reinforcement profile, so that '' depending on its housing engaged with the clips, the same profile is used either as a symmetrical vertical joint cover on either side of a frame profile between two vertical panels or between a vertical panel and a frame, either as an asymmetrical horizontal joint cover in relation to the reinforcement profile between the floor or the ceiling and any panel or glazing bead.
Suivant une forme d'exécution, chaque profilé servant de couvre-joint comporte, sur sa face dorsale, quatre ailes qui présentent des retours dirigés en regard les uns des autres, afin de former trois glissières s'étendant sur toute la longueur du profilé et dont l'une ou l'autre desquelles sert de logement aux têtes de clips métalliques dont les branches coopèrent avec un profilé d'armature.According to one embodiment, each profile serving as a joint cover comprises, on its dorsal face, four wings which have returns directed opposite one another, in order to form three slides extending over the entire length of the profile and one or the other of which serves as a housing for the heads of metal clips whose branches cooperate with an armature profile.
Les profilés d'armature peuvent avoir diverses formes, et c'est ainsi que; suivant un mode avantageux de réalisation de l'invention, un profilé d'armature consiste en une âme rectiligne comportant quatre ailes longitudinales qui lui sont perpendiculaires et qui, grâce à des retours prévus à leurs extrémités, délimitent sur les deux faces du profilé des logements destinés à coopérer avec des organes de fixation, les ailes longitudinales latérales présentant en outre des retours dirigés d'abord vers l'extérieur, puis en regard l'un de l'autre, pour délimiter des logements avec lesquels coopèrent les clips de fixation des profilés servant de couvre-joints.The reinforcement profiles can have various shapes, and that is how; according to an advantageous embodiment of the invention, a reinforcing profile consists of a rectilinear core comprising four longitudinal wings which are perpendicular thereto and which, thanks to returns provided at their ends, delimit on the two faces of the profile of the housings intended to cooperate with fasteners, the lateral longitudinal wings further having returns directed first outwards, then facing one another, to delimit housings with which the fastening clips cooperate profiles used as joint covers.
L'invention sera bien comprise d'ailleurs à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de ce système d'armature pour cloisons préfabriquées et démontables :
- Figures 1 et 2 sont des vues en perspective, respectivement d'un profilé servant de couvre-joint et d'un profilé servant d'armature;
- Figure 3 est une vue en coupe verticale d'une cloison en panneaux pleins reliés à un plancher et à un plafond par de tels profilés;
- Figure 4 est une vue en coupe verticale identique, au niveau d'une huisserie et d'une imposte vitrée;
- Figure 5 est une vue en coupe horizontale au niveau de la jonction de deux cloisons en panneaux pleins et d'un panneau vitré.
- Figures 1 and 2 are perspective views, respectively of a profile serving as a joint cover and a profile serving as a reinforcement;
- Figure 3 is a vertical sectional view of a partition made of solid panels connected to a floor and a ceiling by such profiles;
- Figure 4 is an identical vertical sectional view, at a frame and a transom window;
- Figure 5 is a horizontal sectional view at the junction of two partitions in solid panels and a glass panel.
Qu'il s'agisse de panneaux pleins, de panneaux vitrés, d'huisseries, de parcloses ou autres éléments, le montage d'un cloisonnement préfabriqué conforme à l'invention nécessite l'utilisation des deux types de profilés métalliques, avantageusement en aluminium, représentés respectivement aux figures 1 et 2.Whether they are solid panels, glazed panels, window frames, glazing beads or other elements, the mounting of a prefabricated partitioning according to the invention requires the use of two types of metal profiles, advantageously aluminum , shown respectively in Figures 1 and 2.
La figure 1 montre un profilé destiné à servir de couvre-joint. Ce profilé consiste en une âme 1 présentant, sur sa face dorsale, quatre ailes 2 qui se prolongent chacune par un retour 3 dirigé en regard de l'aile voisine; et chaque retour 3 présente un plan incliné 4. Le profilé ainsi constitué présente, sur sa face arrière, trois logements désignés par 5 et dans chacun desquels l'entrée est facilitée par les pans coupés 4.Figure 1 shows a profile intended to serve as a joint cover. This profile consists of a
Ces logements 5 sont destinés à recevoir les clips 6 dont la tête pénètre facilement de façon élastique à leur intérieur. Chaque profilé présente donc, sur sa face arrière, trois glissières susceptibles de recevoir les têtes des clips 6; mais il est important de noter que chaque profilé ne reçoit de clips 6 que dans l'une ou l'autre de ses glissières 5.These
La figure 2 représente un profilé destiné à servir d'armature au cloisonnement. Ce profilé consiste en une âme 7 dont sont solidaires quatre ailes 8 qui s'étendent perpendiculairement sur ses deux faces. Ces quatre ailes, parallèles entre elles, se terminent par des retours 9 qui délimitent des logements ou glissières 10 s'étendant de façon continue sur toute la longueur du profilé. Il est en outre à noter que les deux ailes latérales 8 possèdent des retours extérieurs 11 qui délimitent deux autres glissières 12 s'étendant sur toute la longueur du profilé, de part et d'autre de son âme 7. Ce sont précisément ces glissières 12 qui sont destinées à coopérer avec les branches des clips 6 pour permettre la fixation des profilés 1 servant de couvre-joints sur les profilés Z servant d'armature.Figure 2 shows a profile intended to serve as a reinforcement for partitioning. This profile consists of a core 7 of which four
Les figures 3 à 5 illustrent quelques utilisations possibles respectivement du profilé d'armature 7 et du profilé de couvre-joint 1.FIGS. 3 to 5 illustrate some possible uses of the reinforcement profile 7 and the
Dans le cas de la figure 3 est représentée en coupe verticale une cloison pleine mise en place entre le plancher 13 et le plafond 14, cette cloison étant constituée de deux panneaux extérieurs 15 constitués en un matériau quelconque, mais placés de part et d'autre d'un panneau central 16 en matériau isolant, par exemple en laine de verre, de roche ou de basalte. Conformément à l'invention, deux profilés d'armature horizontaux Z sont fixés respectivement au sol 13 et au plafond 14, cette fixation étant faite par exemple par vissage. La cloison constituée des éléments 15 et 16 est fixée à deux profilés d'armature 7 par des joints 17 constitués par exemple en néoprène et prenant appui, d'une part, dans les glissières 10 des profiiés 7 et, d'autre part, dans l'espace délimité par les panneaux extérieurs 16 et par le panneau intérieur 15. Il est cependant important de noter que cette fixation est renforcée par les profilés 1 qui jouent simultanément le rôle de couvre-joints. Chacun des quatre profilés 1, placés à la base et au sommet de la cloison, est en effet lié aux deux profilés d'armature 7 par des clips 6 dont les têtes prennent appui dans l'une des glissières latérales 5 des profilés 1 et dont les jambes prennent appui dans les glissières 12 des profilés 7. Tout en contribuant à la fixation de la cloison, les profilés 1 servent bien, comme le montre le dessin, de couvre-joints entre la cloison et le plancher 13 ou le plafond 14; il est d'ailleurs à noter qu'une bonne jonction est réalisée entre le profilé 1 et la cloison, ainsi qu'entre le profilé 1 et le profilé 7, grâce à des joints 18 prévus sur les deux ailes longitudinales 2 du profilé 1.In the case of Figure 3 is shown in vertical section a solid partition placed between the
La figure 4 illustre l'utilisation des profilés d'armature 7 et des profilés de couvre-joints 1 dans le cas d'une huisserie et d'une imposte vitrée vues en coupe verticale sous un plafond . 14 désigne ce plafond, 19 désigne l'imposte vitrée et 20 désigne une porte. Un profilé d'armature 7 est fixé par vissage sous le plafond 14 et un autre profilé d'armature 7 est placé horizontalement sur le cadre 21 de l'huisserie avec laquelle coopère la porte 20. Deux parcloses 22 et 23, en métal ou en matière plastique, sont fixées aux deux profilés d'armature 7, et ce par accrochage aux retours 9 de leurs ailes 8. Ces parcloses sont équipées de joints, respectivement 24 et 25, sur lesquels prend appui le panneau vitré 19 de l'imposte, dont la fixation est réalisée par deux profilés 1. Grâce à des clips 6 prenant appui par leurs têtes dans une glissière 5 du profilé 1 et par leurs jambes dans une glissière 12 du profilé 7, les profilés 1 se trouvent en effet assujettis aux profilés 7, tout en s'appliquant avec étanchéité par leurs joints 18, respectivement soit contre un retour d'une aile du profilé 7 et contre le panneau vitré 19, soit contre ce panneau et contre le cadre 21. Il est en tout cas important de noter qu'à la partie supérieure, c'est-à-dire sous le plafond, les clips de fixation prennent appui dans la glissière supérieure 5 du profilé 1, alors qu'au niveau de la liaison entre le panneau vitré 19 et le cadre 21, les clips de liaison prennent appui dans la glissière médiane 2 du profilé 1.Figure 4 illustrates the use of frame profiles 7 and
La figure 5 illustre enfin, en coupe horizontale, la liaison entre deux cloisons pleines et une huisserie de porte. Les deux cloisons pleines sont constituées, comme dans le cas de la figure 1, par deux panneaux extérieurs 15 et par un panneau intermédiaire 16; l'huisserie est désignée par 27 et la porte par 28. Les deux profilés d'armature 7 sont placés verticalement et orthogonalement l'un par rapport à l'autre, de part et d'autre d'un panneau rigide 29 traversé par une vis 30 qui réalise la liaison entre les deux profilés. Comme dans le cas de la figure 1, la liaison entre les cloisons pleines et les profilés d'armature 7 est réalisée par des joints 17 et par les profilés de couvre-joints 1; et il est bien visible que ces profilés 1 sont liés aux profilés d'armature 7 par des clips 6 prenant appui dans leurs glissières médianes 5 et que ces profilés 1 prennent appui contre les panneaux par l'intermédiaire de leurs joints longitudinaux 18.Figure 5 finally illustrates, in horizontal section, the connection between two solid partitions and a door frame. The two solid partitions are constituted, as in the case of FIG. 1, by two
Il est évident que l'utilisation combinée des profilés d'armature 7 et des profilés de couvre-joints 1 n'est pas limitée aux seuls cas qui ont été ci-dessus indiqués à titre d'exemples; et l'invention ne se limite pas d'ailleurs aux seules formes d'exécution qui ont été ci-dessus indiquées, également à titre d'exemples pour ces deux types de profilés; elle en embrasse, au contraire, toutes les variantes de réalisation.It is obvious that the combined use of reinforcement sections 7 and
