Description

La présente invention concerne essentiellement un procédé et un joint d'étanchéité à lèvre d'étanchéité à sens de courbure inversé.The present invention essentially relates to a method and a seal with a sealing lip with reverse direction of curvature.

Plus particulièrement, l'invention concerne un procédé et un joint pour assurer l'étanchéité notamment au centre d'une croix formée par quatre châssis de menuiserie, par exemple de fenêtres ou de panneaux, notamment d'isolation extérieure de bâtiment.More particularly, the invention relates to a method and a seal for sealing in particular at the center of a cross formed by four carpentry frames, for example of windows or panels, in particular of exterior building insulation.

On sait que dans le bâtiment on est souvent confronté avec des problèmes d'étanchéité entre des châssis de menuiserie, de fenêtres ou de panneaux. On tente généralement de résoudre ces problèmes d'étanchéité grâce à l'emploi d'un joint courant à lèvre d'étanchéité fixé par un pied dans un organe de réception du châssis, tel qu'une gorge ou rainure. La mise en place de ces joints est en général peu aisée. On peut trouver ces joints d'étanchéité du côté extérieur du châssis ou même du côté intérieur, pour renforcer l'étanchéité, mais au niveau de la croix on a un empilage de quatre lèvres simples incurvées ou non créant un noeud d'étanchéité imparfaite.We know that in the building industry we often face sealing problems between frames of carpentry, windows or panels. Attempts are generally made to resolve these sealing problems by using a common seal with a sealing lip fixed by a foot in a body for receiving the chassis, such as a groove or groove. The installation of these seals is generally not easy. These seals can be found on the outside of the chassis or even on the inside, to strengthen the seal, but at the cross there is a stack of four simple lips, curved or not, creating an imperfect seal node.

Il a déjà été proposé dans la technique antérieure d'utiliser des joints d'étanchéité tubulaires. Cependant, les parties tubulaires de ces joints se déforment dans les angles en raison de l'angle du châssis, habituellement à 90°, ce qui conduit à la formation d'un jour ou espace entre les parties tubulaires des joints. Ce jour ou cet espace est plus important lorsqu'on se trouve à la croix formée par quatre châssis.It has already been proposed in the prior art to use tubular seals. However, the tubular parts of these joints deform in the corners due to the angle of the frame, usually 90 °, which leads to the formation of a day or space between the tubular parts of the joints. This day or this space is more important when we are at the cross formed by four frames.

On a déjà proposé par le document FR-A-2 533 001 de résoudre ce problème d'étanchéité entre les châssis, et en particulier au niveau de la croix formée par quatre châssis à l'aide d'un joint d'étanchéité du type tubulaire ayant une section droite sensiblement triangulaire et aplatie, la base étroite du triangle étant du côté du pied du joint de sorte que le joint présente deux faces sensiblement planes à angle aigu, ce joint tubulaire comportant dans les angles une seule face par suppression de l'autre face dans chacun des quatre joints adjacents au niveau des angles, ceci afin d'éviter un empilement excessif de faces (au nombre total de 8) au centre de la croix définie au niveau des angles.Document FR-A-2 533 001 has already proposed to solve this sealing problem between the frames, and in particular at the cross formed by four frames using a seal of the type tubular having a substantially triangular and flattened cross section, the narrow base of the triangle being on the side of the foot of the joint so that the joint has two substantially planar faces at an acute angle, this tubular joint comprising in the corners only one face by removing the 'other face in each of the four adjacent joints at the corners, this in order to avoid excessive stacking of faces (total number of 8) at the center of the cross defined at the corners.

Cette solution présente cependant l'inconvénient de ne pas assurer une étanchéité en toute circonstance en raison de l'espace libre existant entre la partie tubulaire du joint et la partie à une seule lèvre; on retrouve, en outre, la solution antérieure de l'empilage de quatre lèvres, généralement planes, ce qui ne résoud pas le problème technique de l'étanchéité au niveau de la croix.This solution however has the drawback of not ensuring a seal under all circumstances due to the free space existing between the tubular part of the seal and the part with a single lip; there is, in addition, the anterior solution of the stacking of four lips, generally flat, which does not solve the technical problem of sealing at the level of the cross.

La présente invention a donc pour but de résoudre le nouveau problème technique consistant en la fourniture d'une solution permettant d'assurer l'étanchéité entre châssis de menuiserie adjacents, et notamment au centre d'une croix formée par quatre châssis de menuiserie, évitant l'emploi de joints tubulaires grâce à l'emploi de joints à lèvre simple d'étanchéité, de faible coût, tout en assurant une étanchéité parfaite, en particulier au niveau de ladite croix.The present invention therefore aims to solve the new technical problem of providing a solution for sealing between adjacent carpentry frames, and in particular at the center of a cross formed by four carpentry frames, avoiding the use of tubular seals thanks to the use of simple sealing lip seals, of low cost, while ensuring perfect sealing, in particular at the level of said cross.

La présente invention a encore pour but de résoudre le nouveau problème technique ci-dessus d'une manière extrêmement simple, permettant un montage aisé des châssis de menuiserie.The present invention also aims to solve the new technical problem above in an extremely simple manner, allowing easy mounting of the carpentry frames.

Ces problèmes techniques sont résolus pour la première fois d'une manière particulièrement simple, sûre, peu coûteuse, utilisable à l'échelle industrielle.These technical problems are solved for the first time in a particularly simple, safe, inexpensive manner, usable on an industrial scale.

Ainsi, selon un premier aspect, la présente invention fournit un procédé pour assurer l'étanchéité entre châssis de menuiserie adjacents, notamment au centre d'une croix formée par quatre châssis de menuiserie, par exemple de fenêtre ou de panneaux, dans lequel on utilise un joint courant à lèvre simple d'étanchéité montable sur le pourtour de chacun des châssis, caractérisé en ce qu'on prévoit un joint courant à lèvre simple d'étanchéité incurvée comprenant une inversion de sens de courbure dans les parties du joint destinées à être positionnées sensiblement verticalement dans les parties verticales dudit châssis de menuiserie, ledit joint comprenant ainsi une partie de lèvre verticale incurvée vers l'extérieur et une partie de lèvre verticale incurvée vers l'intérieur, relativement au châssis; on dispose chaque joint sur son châssis associé de telle sorte que la partie de lèvre incurvée vers l'extérieur soit au-dessus de la partie de lèvre incurvée vers l'intérieur; et on pose le châssis de sorte à réaliser un tuilage desdites lèvres incurvées, en particulier dans la zone de la croix formée par quatre châssis, en obtenant ainsi une étanchéité parfaite en particulier au niveau de la croix définie entre plusieurs châssis.Thus, according to a first aspect, the present invention provides a method for sealing between adjacent carpentry frames, in particular at the center of a cross formed by four carpentry frames, for example window or panels, in which one uses a common seal with a simple sealing lip which can be mounted on the periphery of each of the chassis, characterized in that a common seal with a simple curved sealing lip is provided comprising an inversion of the direction of curvature in the parts of the seal intended to be positioned substantially vertically in the vertical parts of said carpentry frame, said seal thus comprising a vertical lip part curved outwards and a vertical lip part curved inwards, relative to the frame; we have each joint on its associated frame so that the outwardly curved lip portion is above the inwardly curved lip portion; and the frame is placed so as to produce a curling of said curved lips, in particular in the area of the cross formed by four frames, thereby obtaining perfect sealing in particular at the cross defined between several frames.

Selon une caractéristique particulièrement avantageuse du procédé selon l'invention, celui-ci est caractérisé en ce qu'on prévoit l'inversion du sens de courbure de la lèvre d'étanchéité en un point sensiblement médian de la lèvre verticale. Ce point sensiblement médian correspond généralement sensiblement à un plan de symétrie du joint d'étanchéité.According to a particularly advantageous characteristic of the method according to the invention, it is characterized in that provision is made for reversing the direction of curvature of the sealing lip at a substantially mid-point of the vertical lip. This substantially median point generally corresponds substantially to a plane of symmetry of the seal.

Selon un mode de réalisation particulièrement avantageux du procédé selon l'invention, on prévoit l'inversion du sens de courbure de la lèvre d'étanchéité en un point supérieur de ladite lèvre. Selon une autre variante de réalisation, on prévoit cette inversion du sens de courbure de la lèvre d'étanchéité en un point inférieur de ladite lèvre.According to a particularly advantageous embodiment of the method according to the invention, provision is made for reversing the direction of curvature of the sealing lip at an upper point of said lip. According to another alternative embodiment, this reversal of the direction of curvature of the sealing lip is provided at a lower point of said lip.

Selon une autre caractéristique avantageuse du procédé selon l'invention, on réalise l'inversion de courbure de la lèvre par moulage approprié du joint d'étanchéité. Une variante de réalisation consiste à réaliser une solidarisation de deux demi-lèvres à sens de courbure inversé par tout moyen approprié, tel que collage ou vulcanisation des bords des deux demi-lèvres adjacentes.According to another advantageous characteristic of the method according to the invention, the curvature of the lip is reversed by appropriate molding of the seal. An alternative embodiment consists in securing two half-lips with reverse curvature by any suitable means, such as bonding or vulcanization of the edges of the two adjacent half-lips.

Selon une autre caractéristique avantageuse de l'invention, la courbure de la lèvre d'étanchéité est telle que lors du tuilage on réalise une compression des lèvres, ce qui favorise grandement l'étanchéité.According to another advantageous characteristic of the invention, the curvature of the sealing lip is such that during curling compression of the lips is carried out, which greatly promotes sealing.

Selon une autre caractéristique avantageuse de l'invention, les lèvres horizontales du joint ont le même sens de courbure que la partie de lèvre verticale adjacente, ce qui favorise le tuilage et l'obtention d'une étanchéité parfaite.According to another advantageous characteristic of the invention, the horizontal lips of the joint have the same direction of curvature as the adjacent vertical lip part, which promotes curling and obtaining a perfect seal.

Naturellement, la section de la lèvre du joint d'étanchéité peut varier en fonction du jeu existant entre les châssis. Ces lèvres peuvent être réalisées en élastomère vulcanisé ou en matériau thermoplastique.Naturally, the section of the lip of the seal can vary depending on the clearance existing between the frames. These lips can be made of vulcanized elastomer or of thermoplastic material.

Selon un deuxième aspect, la présente invention concerne également un joint d'étanchéité assurant une étanchéité notamment au centre d'une croix formée par quatre châssis de menuiserie adjacents, comprenant un joint courant à lèvre simple d'étanchéité montable sur le pourtour de chacun des châssis grâce à un pied insérable dans un organe de réception du châssis, tel qu'une rainure, caractérisé en ce que ladite lèvre d'étanchéité est une lèvre simple incurvée comprenant une inversion de sens de courbure dans les parties de joint destinées à être positionnées sensiblement verticalement dans les parties verticales dudit châssis de menuiserie, ledit joint comprenant ainsi une partie de lèvre verticale incurvée vers l'extérieur et une partie de lèvre verticale incurvée vers l'intérieur relativement au châssis; ladite partie de lèvre incurvée vers l'extérieur étant située au-dessus de la partie de lèvre incurvée vers l'intérieur.According to a second aspect, the present invention also relates to a seal ensuring a seal in particular at the center of a cross formed by four adjacent carpentry frames, comprising a common seal with simple sealing lip mountable on the periphery of each of the frame by means of a foot insertable into a frame receiving member, such as a groove, characterized in that said sealing lip is a simple curved lip comprising a reversal of direction of curvature in the joint parts intended to be positioned substantially vertically in the vertical parts of said carpentry frame, said seal thus comprising a vertical lip part curved outwards and a vertical lip part curved inwards relative to the frame; said outwardly curved lip portion being located above the inwardly curved lip portion.

Ainsi, l'écoulement éventuel de l'eau a lieu dans la rigole définie par la partie de lèvre incurvée vers l'extérieur située dans la partie supérieure du joint d'étanchéité et se poursuit ensuite sur la partie de lèvre incurvée vers l'intérieur pour être encore guidé dans la rigole définie par la partie de lèvre incurvée vers l'extérieur du joint du châssis suivant situé au-dessous du châssis en question. Naturellement, les modes ou variantes de réalisation de ce joint peuvent être tels que définis précédemment en relation avec le procédé.Thus, the possible flow of water takes place in the channel defined by the outwardly curved lip portion located in the upper part of the seal and then continues on the inwardly curved lip portion. to be further guided in the channel defined by the lip part curved towards the outside of the seal of the following chassis located below the chassis in question. Naturally, the embodiments or variants of this joint can be as defined above in relation to the process.

On comprend ainsi que ce joint d'étanchéité soit simplifié, soit d'un faible coût de fabrication, d'un montage aisé, utilisable à l'échelle industrielle.It is thus understood that this seal is simplified, that is to say a low manufacturing cost, an easy assembly, usable on an industrial scale.

D'autres buts, caractéristiques et avantages de l'invention apparaîtront clairement à la lumière de la description explicative qui va suivre faite en référence aux dessins annexés représentant plusieurs modes de réalisation d'un joint d'étanchéité selon l'invention, donnés simplement à titre d'illustration et qui ne sauraient donc en aucune façon limiter la portée de l'invention.Other objects, characteristics and advantages of the invention will appear clearly in the light of the explanatory description which will follow made with reference to the appended drawings representing several embodiments of a seal according to the invention, given simply by title of illustration and which could not in any way limit the scope of the invention.

Ce pied 14 peut présenter diverses formes adaptables aux différentes rainures ou gorges des châssis pouvant se trouver sur le marché.With particular reference to FIGS. 1 and 2, a seal according to the invention, represented by the general reference number 10, is a common seal with a simple lip 12 seal mountable on the periphery of a carpentry frame (not shown) by means of a foot 14 which can be inserted into a body for receiving the chassis, such as a groove. This foot 14 may have various shapes adaptable to the different grooves or grooves of the frames which may be on the market.

Selon l'invention, la lèvre d'étanchéité 12 est une lèvre simple incurvée comprenant une inversion 16 du sens de courbure dans les parties du joint 10 destinées à être positionnées sensiblement verticalement dans les parties verticales dudit châssis de menuiserie.According to the invention, the sealing lip 12 is a simple curved lip comprising an inversion 16 of the direction of curvature in the parts of the joint 10 intended to be positioned substantially vertically in the vertical parts of said carpentry frame.

Ce joint comprend ainsi deux lèvres verticales référencées 12V1, 12V2 et deux lèvres horizontales 12H1, 12H2, respectivement. En outre, chaque lèvre verticale 12V1, 12V2 se subdivise en pratique en une partie de lèvre verticale incurvée vers l'extérieur référencée 12V1A, 12V2A, respectivement, et une partie de lèvre verticale incurvée vers l'intérieur 12V1B, 12V2B, respectivement, relativement au châssis, en position montée, en considérant que le châssis comprend un bord intérieur dirigé vers l'intérieur de la construction du bâtiment et un bord extérieur apparent de l'extérieur ou en contact avec l'extérieur.This joint thus comprises two vertical lips referenced 12V1, 12V2 and two horizontal lips 12H1, 12H2, respectively. In addition, each vertical lip 12V1, 12V2 is subdivided in practice into a part of an outwardly curved vertical lip referenced 12V1A, 12V2A, respectively, and a part of an inwardly curved vertical lip 12V1B, 12V2B, respectively, relative to the chassis, in the assembled position, considering that the chassis comprises an interior edge directed towards the interior of the building construction and an exterior edge apparent from the exterior or in contact with the exterior.

Selon l'invention, la partie de lèvre incurvée vers l'extérieur, c'est-à-dire la partie 12V1A, 12V2A, est disposée au-dessus de la partie de lèvre incurvée vers l'intérieur, à savoir la partie 12V1B, 12V2B. Les parties de lèvre 12V2A, 12V2B de part et d'autre du point d'inversion 16 sont clairement visibles à la figure 2 ainsi qu'à la figure 5.According to the invention, the outwardly curved lip part, that is to say the 12V1A, 12V2A part, is arranged above the inwardly curved lip part, namely the 12V1B part, 12V2B. The lip parts 12V2A, 12V2B on either side of the reversal point 16 are clearly visible in FIG. 2 as well as in FIG. 5.

Selon un mode de réalisation avantageux de l'invention, le point d'inversion 16 du sens de courbure de la lèvre verticale 12V1, 12V2 est disposé en un point sensiblement médian de la lèvre verticale, selon le mode de réalisation représenté aux figures 1, 2 et 5 à 9. Cependant, selon une variante de réalisation (figure 3), le point d'inversion 116 du sens de courbure de la lèvre 112 est disposé en un point inférieur de la lèvre 112, c'est-à-dire que la dimension ou la longueur de la partie de lèvre 112V1A occupe pratiquement toute la dimension ou la longueur de la lèvre 112, tandis que la dimension ou la longueur de la partie de lèvre inversée 112V1B est réduite ou presque inexistante, comme clairement visible à la figure 3.According to an advantageous embodiment of the invention, the point of inversion 16 of the direction of curvature of the vertical lip 12V1, 12V2 is arranged at a substantially median point of the vertical lip, according to the embodiment shown in FIGS. 1, 2 and 5 to 9. However, according to an alternative embodiment (FIG. 3), the point of reversal 116 of the direction of curvature of the lip 112 is arranged at a lower point of the lip 112, that is to say that the dimension or the length of the lip part 112V1A occupies practically the whole dimension or the length of the lip 112, while the dimension or the length of the inverted lip part 112V1B is reduced or almost nonexistent, as clearly visible on the figure 3.

Selon une autre variante de réalisation représentée à la figure 4, le point d'inversion 216 du sens de courbure de la lèvre est disposé en un point supérieur de la lèvre 212. On observera que dans ce cas c'est au contraire la partie supérieure 212V1A de la lèvre verticale qui est de dimension ou longueur extrêmement réduite alors que la partie inférieure de la lèvre verticale 212V1B occupe pratiquement toute la dimension ou la longueur de la lèvre verticale 212V1 ou V2.According to another alternative embodiment shown in FIG. 4, the point of reversal 216 of the direction of curvature of the lip is arranged at an upper point of the lip 212. It will be observed that in this case it is on the contrary the upper part 212V1A of the vertical lip which is of dimension or length extremely reduced whereas the lower part of the vertical lip 212V1B occupies practically all the dimension or the length of the vertical lip 212V1 or V2.

Dans tous les cas, il est préféré que les lèvres horizontales telles que 12H1, 12H2 présentent le même sens de courbure que la partie de lèvre verticale adjacente, telle que 12V1A, 12V2A; 12V1B, 12V2B, respectivement.In all cases, it is preferred that the horizontal lips such as 12H1, 12H2 have the same direction of curvature as the adjacent vertical lip portion, such as 12V1A, 12V2A; 12V1B, 12V2B, respectively.

Selon un mode de réalisation particulier, la section de la lèvre peut varier en fonction du jeu existant entre les châssis. Ceci s'applique également aux lèvres verticales 12V1, 12V2 et aux lèvres horizontales 12H1, 12H2.According to a particular embodiment, the section of the lip can vary as a function of the clearance existing between the frames. This also applies to the vertical lips 12V1, 12V2 and to the horizontal lips 12H1, 12H2.

Ces lèvres peuvent être réalisées en tout matériau approprié, notamment en élastomère vulcanisé ou en matériau thermoplastique.These lips can be made of any suitable material, in particular of vulcanized elastomer or of thermoplastic material.

Selon une autre caractéristique avantageuse du joint selon l'invention, la courbure des lèvres 12V1, 12V2, 12H1, 12H2 est telle que lors du tuilage réalisé lors de la pose des châssis, notamment lorsqu'il s'agit de châssis de menuiserie de panneaux d'isolation extérieure, on réalise une compression des lèvres 12V1, 12V2, 12H1, 12H2.According to another advantageous characteristic of the seal according to the invention, the curvature of the lips 12V1, 12V2, 12H1, 12H2 is such that during the curling carried out during the installation of the frames, in particular when it is a frame of frames for panels external insulation, lips 12V1, 12V2, 12H1, 12H2 are compressed.

Selon une caractéristique particulièrement avantageuse, la courbure des lèvres verticales 12V1, 12V2 est identique à la courbure des lèvres horizontales 12H1, 12H2. Cependant, selon certaines variantes, on peut prévoir des courbures différentes entre les lèvres verticales 12V1, 12V2 et les lèvres horizontales 12H1, 12H2. Il en est de même des dimensions des lèvres elles-mêmes, pour tenir compte des jeux existants entre les châssis, notamment en fonction de l'aspect esthétique recherché sur l'apparence extérieure des façades.According to a particularly advantageous characteristic, the curvature of the vertical lips 12V1, 12V2 is identical to the curvature of the horizontal lips 12H1, 12H2. However, according to certain variants, it is possible to provide different curvatures between the vertical lips 12V1, 12V2 and the horizontal lips 12H1, 12H2. The same applies to the dimensions of the lips themselves, to take account of the play existing between the frames, in particular as a function of the desired aesthetic appearance on the external appearance of the facades.

Selon une autre caractéristique particulièrement avantageuse de l'invention, le joint d'étanchéité selon l'invention est destiné à être plus particulièrement placé à l'intérieur des châssis, c'est-à-dire vers le bord intérieur ou arrière, non apparent des châssis.According to another particularly advantageous characteristic of the invention, the seal according to the invention is intended to be more particularly placed inside the frames, that is to say towards the inner or rear edge, not visible chassis.

Il peut cependant être également utilisé vers le bord extérieur, avant ou apparent des châssis.However, it can also be used towards the outer, front or visible edge of the chassis.

Le joint d'étanchéité selon l'invention peut être fabriqué par tous procédés de fabrication classique des joints que l'homme de l'art connaît bien. Par exemple, il peut être fabriqué sans problème, malgré le point d'inversion, par coulage ou moulage, ou encore par solidarisation de deux demi-lèvres telles que 12V1A, 12V1B de la lèvre verticale 12V1, à sens de courbure inverse, par tous moyens appropriés de solidarisation, tels que collage ou vulcanisation. Cependant, la technique de coulage ou moulage est préférée, en raison de sa simplicité.The seal according to the invention can be manufactured by any conventional manufacturing process for seals which those skilled in the art are well aware of. For example, it can be manufactured without problem, despite the reversal point, by pouring or molding, or even by joining two half-lips such as 12V1A, 12V1B of the vertical lip 12V1, in the opposite direction of curvature, by all appropriate means of joining, such as bonding or vulcanization. However, the casting or molding technique is preferred, because of its simplicity.

On comprend ainsi que grâce au joint d'étanchéité selon l'invention, on puisse aboutir à tous les avantages techniques précédemment énoncés de simplicité, de faible coût de fabrication, de rapidité de montage, et d'étanchéité parfaite, en particulier au niveau de la croix définie entre les angles de panneaux adjacents.It is thus understood that, thanks to the seal according to the invention, it is possible to achieve all of the previously stated technical advantages of simplicity, low manufacturing cost, speed of assembly, and perfect sealing, in particular in terms of the cross defined between the angles of adjacent panels.

Ce joint d'étanchéité permet ainsi la mise en oeuvre du procédé précédemment énoncé, et qui est décrit en détail en référence avec les figures 5 à 9.This seal thus allows the implementation of the method previously stated, and which is described in detail with reference to FIGS. 5 to 9.

Ce procédé, après avoir prévu le joint tel que précédemment défini, comprend l'étape de disposer chaque joint 10, 10′, 10˝ ou 10‴ sur son châssis associé (non représenté par simplification) de telle sorte que la partie de lèvre incurvée vers l'extérieur telle que 12V1A, 12V2A, soit disposée au-dessus de la partie de lèvre incurvée vers l'intérieur, telle que 12V1B, 12V2B. Il en est de même des joints adjacents 10′, 10˝ et 10‴.This method, after having provided the joint as defined above, comprises the step of placing each joint 10, 10 ′, 10˝ or 10 ‴ on its associated frame (not shown for simplification) so that the lip part curved outward such as 12V1A, 12V2A, is disposed above the inwardly curved lip portion, such as 12V1B, 12V2B. The same applies to the adjacent joints 10 ′, 10˝ and 10 ‴.

Ensuite, on pose les châssis de sorte à réaliser un tuilage des lèvres incurvées. Ainsi, par exemple, le joint 10 a sa lèvre verticale 12V2 qui vient se positionner sur la lèvre verticale 12V1 du joint 10′ de telle sorte que la partie supérieure de lèvre 12V2A vient se positionner sur la partie supérieure de lèvre 12V1A′ et de même pour la partie inférieure de lèvre 12V2B sur la partie inférieure de lèvre 12V1B′.Then, the frames are placed so as to produce a curling of the curved lips. Thus, for example, the seal 10 has its vertical lip 12V2 which is positioned on the vertical lip 12V1 of the seal 10 ′ so that the upper lip part 12V2A is positioned on the upper lip part 12V1A ′ and likewise for the lower lip 12V2B on the lower lip 12V1B ′.

En outre, le joint 10˝ du châssis supérieur de menuiserie par exemple de fenêtres, ou de panneaux d'isolation extérieure a sa lèvre horizontale inférieure 12H2˝, dont on doit remarquer que le sens de courbure, qui est identique à celui des parties inférieures 12V1B et 12V2B des lèvres verticales 12V1, 12V2, avec un sens inverse de courbure par rapport à la lèvre horizontale supérieure 12H1 du joint d'étanchéité 10. La lèvre horizontale supérieure 12H1 a un sens de courbure qui est tourné vers l'extérieur, au contraire de la lèvre horizontale inférieure 12H2 qui a un sens de courbure tourné vers l'intérieur. De cette manière, la lèvre horizontale inférieure 12H2˝ du joint 10˝ vient se positionner au-dessus de la lèvre horizontale supérieure 12H1 du joint 10. Il en est de même par analogie avec les joints 10 et 10‴. Ces positionnements, après tuilage, sont clairement visibles sur les coupes des figures 6 à 9.In addition, the seal 10˝ of the upper frame of carpentry, for example of windows, or of external insulation panels has its lower horizontal lip 12H2˝, of which it should be noted that the direction of curvature, which is identical to that of the lower parts 12V1B and 12V2B of the vertical lips 12V1, 12V2, with an opposite direction of curvature with respect to the upper horizontal lip 12H1 of the seal 10. The upper horizontal lip 12H1 has a direction of curvature which is turned outwards, opposite of the lower horizontal lip 12H2 which has a direction of curvature turned inward. In this way, the lip lower horizontal 12H2˝ of the seal 10˝ is positioned above the upper horizontal lip 12H1 of the seal 10. It is the same by analogy with the seals 10 and 10 ‴. These positions, after curling, are clearly visible in the sections of Figures 6 to 9.

On comprend ainsi que ce tuilage assure une étanchéité parfaite et permet à l'eau d'infiltration ou de condensation de s'écouler dans les rigoles verticales 12V1A, 12V2A ou 12V1′A, 12V2A pour passer ensuite sur les parties de lèvres inférieures 12V1B, 12V2B avant de s'écouler ensuite dans les rigoles des lèvres verticales des joints 10‴ disposés en-dessous des parties verticales inférieures précédentes.It is thus understood that this tiling provides a perfect seal and allows the infiltration or condensation water to flow into the vertical channels 12V1A, 12V2A or 12V1′A, 12V2A and then pass over the lower lip parts 12V1B, 12V2B before then flowing into the channels of the vertical lips of the seals 10 ‴ arranged below the previous lower vertical parts.

Cette étanchéité parfaite est en particulier obtenue dans la zone de croix 20 définie par les angles de quatre châssis adjacents.This perfect seal is in particular obtained in the cross region 20 defined by the angles of four adjacent frames.

Il est bien entendu que diverses variantes de réalisation de l'invention sont possibles. En particulier, lorsque la section de la lèvre est relativement grande, on peut prévoir que le profil de la lèvre du côté du pied du joint soit sensiblement rectiligne, alors que le profil de la lèvre présente la courbure précitée du côté libre (opposé au pied) de la lèvre.It is understood that various alternative embodiments of the invention are possible. In particular, when the section of the lip is relatively large, provision may be made for the profile of the lip on the side of the foot of the joint to be substantially straight, while the profile of the lip has the aforementioned curvature on the free side (opposite the foot ) of the lip.

On comprend ainsi que l'on obtient tous les avantages techniques déterminants précédemment énoncés de manière particulièrement simple, inattendue pour un homme de l'art.It is thus understood that one obtains all the determining technical advantages previously stated in a particularly simple manner, unexpected for a person skilled in the art.
