One of the faces of these Vs preferably parallel to the plane of the panels, thus effectively and in a leaktight manner, holding the panels in the event of horizontal stresses. The fastening pieces come into contact with the external section pieces in order to prevent them from moving away from the support. <IMAGE>

Description

La présente invention est relative à un ensemble à panneaux sandwich destiné principalement au bardage de bâtiments, pouvant servir aussi à la constitution de toitures ou de cloisons intérieures.The present invention relates to a set of sandwich panels intended mainly for cladding of buildings, which can also be used for the constitution of roofs or interior partitions.

De tels panneaux sont formés d'une âme en matière isolante, thermique et/ou phonique, placée entre deux profilés métalliques, les panneaux sont destinés à être montés sur un support de telle façon qu'ils soient jointifs le long des bords des profilés. Le montage est fait à l'aide de moyens de fixation qui sont, par exemple, vissés dans le support.Such panels are formed of a core of insulating, thermal and / or sound material, placed between two metal profiles, the panels are intended to be mounted on a support so that they are joined along the edges of the profiles. The mounting is done using fixing means which are, for example, screwed into the support.

La conception d'un panneau sandwich doit répondre à des exigences multiples, concernant la sécurité, l'aspect esthétique et le prix de revient. Notamment :

  • le profilé extérieur, c'est-à-dire celui qui est à l'opposé du support, doit être accroché physiquement aux moyens de fixation, pour éviter qu'une séparation entre ce profilé et l'âme n'entraîne un départ du profilé, qui peut être dangereux,
  • la fixation doit permettre une libre dilatation des panneaux, pour éviter une fatigue alternée des moyens de fixation et/ou des déformations disgracieuses des panneaux. Ceci implique de prévoir des moyens de fixation qui ne traversent pas les profilés, mais sont insérés dans le joint entre panneaux adjacents,
  • les surfaces extérieures de deux panneaux adjacents doivent, si possible, être maintenues dans le même plan, même si un panneau est sollicité différemment de ses voisins, pour éviter des effets de gradins, inesthétiques, surtout en éclairage rasant.
  • les joints entre éléments adjacents doivent présenter un emboîtement continu sur toute leur longueur, pour réduire les pertes thermiques et les risques de passage d'air,
  • la mise en place de panneaux à joints à emboîtement doit se faire sans qu'il en résulte des forces transversales susceptibles de déformer le bord des profilés,
  • dans le cas d'une âme constituée de mousse formée en place, la forme des bords des profilés, notamment pour des joints à emboîtement, doit permettre d'éviter tout défaut de remplissage,
  • les caches recouvrant les joints entre panneaux doivent être évités si possible, pour minimiser les prix de revient,
  • en l'absence de caches, les joints apparents doivent suffisamment être larges pour que les petites variations de la largeur de ces joints, dues à des différences de température ou à des tolérances de fabrication, soient peu visibles,
  • avantageusement, des panneaux d'épaisseur différente pourront être réalisés avec les mêmes profilé&s extérieurs et intérieurs, en changeant seulement l'épaisseur de l'âme isolante, et ces profilés seront calculés pour permettre l'obtention de panneaux d'épaisseur faible, et donc de faible coût, là où une isolation plus faible est acceptée,
  • les moyens de fixation doivent être de prix de revient peu élevé, faciles à poser, et de préférence empilables.
The design of a sandwich panel must meet multiple requirements, concerning security, aesthetic appearance and cost price. Especially :
  • the outer profile, that is to say the one which is opposite the support, must be physically attached to the fixing means, to prevent a separation between this profile and the core does not cause a departure of the profile , which can be dangerous,
  • the fixing must allow free expansion of the panels, to avoid alternating fatigue of the fixing means and / or unsightly deformations of the panels. This implies providing fixing means which do not pass through the profiles, but are inserted in the joint between adjacent panels,
  • the exterior surfaces of two adjacent panels should, if possible, be kept in the same plane, even if a panel is stressed differently from its neighbors, to avoid unattractive, tiered effects, especially in low-angle lighting.
  • the joints between adjacent elements must have a continuous interlocking over their entire length, to reduce heat loss and the risk of air passage,
  • the installation of panels with interlocking joints must be done without resulting transverse forces liable to deform the edge of the profiles,
  • in the case of a core made of foam formed in place, the shape of the edges of the profiles, in particular for interlocking joints, must make it possible to avoid any filling defect,
  • the covers covering the joints between panels should be avoided if possible, to minimize cost prices,
  • in the absence of covers, the visible joints must be large enough so that small variations in the width of these joints, due to temperature differences or to manufacturing tolerances, are hardly visible,
  • advantageously, panels of different thickness may be produced with the same external and internal profiles, by only changing the thickness of the insulating core, and these profiles will be calculated to allow obtaining panels of small thickness, and therefore low cost, where lower insulation is accepted,
  • the fastening means must be of low cost price, easy to install, and preferably stackable.

Les panneaux qui sont actuellement proposés ne permettent pas de répondre de façon satisfaisante à la totalité de ces exigences pour un prix de revient modéré.The panels which are currently offered do not make it possible to satisfactorily meet all of these requirements for a moderate cost price.

Par exemple, FR-A-2.398.855, EP-A-522.992 et FR-A-2.449.917 décrivent des types de panneaux qui sont fixés par des rivets, des pointes ou des vis traversant des rebords des profilés, et qui sont dépourvues de moyen pour aligner avec précision des panneaux voisins.For example, FR-A-2,398,855, EP-A-522,992 and FR-A-2,449,917 describe types of panels which are fixed by rivets, points or screws passing through edges of the profiles, and which are lacking means to precisely align neighboring panels.

Dans le document DE-A-2.155.117, qui est en dehors du domaine des panneaux sandwich, on décrit des panneaux de bois, de contreplaqué, ou de particules agglomérées pourvus sur leur face extérieure d'un revêtement protecteur, de préférence métallique. Un des bords du revêtement passe du côté de la face intérieure du panneau pour y être cloué sur une charpente porteuse. Ce bord présente un saillant et un rentrant, à section en V, qui coopèrent avec un rentrant et un saillant de forme adaptée du bord du panneau adjacent, de façon à assurer à la fois l'étanchéité et le maintien dans un même plan des panneaux adjacents.Document DE-A-2,155,117, which is outside the field of sandwich panels, describes panels of wood, plywood, or agglomerated particles provided on their outer face with a protective coating, preferably metallic. One of the edges of the covering passes to the side of the interior face of the panel to be nailed to a load-bearing structure. This edge has a protrusion and a reentrant, V-section, which cooperate with a reentrant and a protruding shape adapted from the edge of the adjacent panel, so as to ensure both the sealing and the maintenance in the same plane of the panels adjacent.

FR-A-2.550.260 décrit des panneaux dont les deux profilés extérieurs sont retenus physiquement par des moyens de fixation insérés dans le joint entre panneaux adjacents, mais où le moyen de fixation, serré avec force dans une rainure d'un profilé extérieur et sur une saille de l'autre, ne garantit pas avec certitude une libre dilatation.FR-A-2,550,260 describes panels, the two external profiles of which are physically retained by fixing means inserted in the joint between adjacent panels, but where the fixing means, tightened forcefully in a groove of an external profile and on one side of the other, does not guarantee with certainty a free expansion.

WO-A-89.12149 décrit des panneaux dont un profilé extérieur est retenu directement par le moyen de fixation, et le profilé extérieur du panneau adjacent est retenu par le premier, la libre dilatation étant cependant possible, mais rien n'est prévu pour maintenir efficacement les panneaux dans un même plan.WO-A-89.12149 describes panels of which an external profile is retained directly by the fixing means, and the external profile of the adjacent panel is retained by the first, free expansion being however possible, but nothing is provided to maintain it effectively the panels in the same plane.

La présente invention a pour but de fournir un ensemble à panneaux sandwich qui réponde au mieux à toutes les exigences indiquées plus haut, et qui soit cependant simple,d'un coût peu élevé et d'une mise en place facile.The object of the present invention is to provide a sandwich panel assembly which best meets all the requirements indicated above, and which is however simple, of low cost and of easy installation.

Pour obtenir ce résultat, l'invention fournit un ensemble destiné à constituer une paroi de bâtiment, comprenant au moins deux panneaux sandwich ayant des faces principales extérieure et intérieure de forme générale plane, allongée, un premier panneau ayant un bord longitudinal supérieur et le deuxième panneau ayant un bord longitudinal inférieur, et ces deux bords coopérant pour former un joint sensiblement étanche lorsque les panneaux sont superposés avec leurs faces principales verticales,
   ledit bord inférieur présentant un premier saillant, dont une première face se raccorde à la face principale extérieure du panneau et une deuxième face, opposée à la première, et plus proche de la face principale intérieure du panneau, est parallèle à ladite face principale extérieure, ce premier saillant étant suivi directement, en direction de l'intérieur, par un premier rentrant,
   ledit bord supérieur présentant un renfoncement, dans lequel peut avancer le premier saillant du bord inférieur, suivi, en direction de la face longitudinale intérieure, d'un premier saillant qui pénètre dans le premier rentrant du bord inférieur du panneau associé, et dont une face est tournée vers l'extérieur,
   chaque panneau sandwich étant formé d'une âme en matière d'isolation sur laquelle est fixé, pour former la face extérieure principale extérieure, un profilé métallique extérieur dont un bord inférieur constitue au moins ledit premier saillant et le premier rentrant du bord inférieur et le renfoncement et le premier saillant du bord supérieur, un profilé métallique intérieur étant fixé sur l'âme pour former la face principale intérieure,
   l'ensemble comprenant en outre une pièce de fixation apte à être fixée sur un support et à être insérée dans le joint entre les panneaux quand ceux-ci sont superposés, et
   la face du premier rentrant du bord inférieur qui est opposée au premier saillant comportant une partie d'appui sur laquelle vient en contact une partie, d'orientation analogue, de la pièce de fixation, ces parties étant orientées pour s'opposer à un déplacement du panneau par rapport à la pièce de fixation et au support en direction de l'extérieur,
   cet ensemble présentant pour particularités que le premier rentrant du bord inférieur de panneau fait est à section en V, avec une face opposée au premier saillant qui fait avec la direction des faces extérieures un angle compris entre 10 et 80° environ,
   que le premier saillant du bord supérieur du panneau est à section en V, à faces parallèles à celle dudit premier rentrant, et est apte à venir en contact, par ses deux faces, avec les deux faces dudit premier rentrant,
   et que ladite partie d'appui est portée par un renfoncement du profilé inférieur, et/ou fait face à un renfoncement du bord supérieur, la position et la forme de ce renfoncement étant calculées pour que la pièce de fixation n'empêche pas le contact des faces obliques de la rainure et du saillant en V.To obtain this result, the invention provides an assembly intended to constitute a building wall, comprising at least two sandwich panels having main exterior and interior faces of generally planar, elongated shape, a first panel having an upper longitudinal edge and the second panel having a lower longitudinal edge, and these two edges cooperating to form a substantially leaktight seal when the panels are superimposed with their main vertical faces,
said lower edge having a first projection, a first face of which is connected to the main external face of the panel and a second face, opposite the first, and closer to the face main interior of the panel, is parallel to said main exterior face, this first projection being followed directly, in the direction of the interior, by a first re-entrant,
said upper edge having a recess, in which the first projection of the lower edge can advance, followed, in the direction of the inner longitudinal face, by a first projection which penetrates into the first reentrant of the lower edge of the associated panel, and one face of which is facing outwards,
each sandwich panel being formed from a core of insulating material to which is fixed, to form the outer main exterior face, an exterior metal profile, a lower edge of which constitutes at least said first protrusion and the first re-entrant from the lower edge and the recess and the first projection of the upper edge, an inner metal profile being fixed on the core to form the inner main face,
the assembly further comprising a fixing part capable of being fixed on a support and of being inserted into the joint between the panels when the latter are superimposed, and
the face of the first re-entrant from the lower edge which is opposite to the first projection comprising a bearing part on which a part, of similar orientation, comes into contact with the fixing part, these parts being oriented to oppose a displacement of the panel in relation to the fixing part and to the support towards the outside,
this assembly having the peculiarities that the first re-entrant from the lower edge of the panel made has a V-section, with a face opposite to the first projection which forms an angle of between 10 and 80 ° with the direction of the external faces,
that the first projection of the upper edge of the panel has a V-section, with faces parallel to that of said first re-entrant, and is capable of coming into contact, by its two faces, with the two faces of said first reentrant,
and that said bearing portion is carried by a recess in the lower profile, and / or faces a recess in the upper edge, the position and the shape of this recess being calculated so that the fixing piece does not prevent contact oblique faces of the groove and the V-shaped projection

Par "extérieur" ou "intérieur", on se réfère à la position du panneau par rapport à l'environnement du bâtiment, lorsque le panneau est utilisé en bardage, et par "supérieur" et "inférieur" on se réfère à la position des bords du panneau lorsque les panneaux sont superposés, avec leurs bords longitudinaux horizontaux. Dans d'autres situations, les mots ci-dessus sont arbitraires.By "exterior" or "interior", we refer to the position of the panel relative to the environment of the building, when the panel is used in cladding, and by "upper" and "lower" we refer to the position of the edges of the panel when the panels are superimposed, with their horizontal longitudinal edges. In other situations, the above words are arbitrary.

Selon l'invention, le bord supérieur du panneau présente un saillant à section en V dont une face est parallèle au plan des profilés et l'autre est oblique sur ce plan, et le bord inférieur du panneau présente un rentrant de forme adaptée.According to the invention, the upper edge of the panel has a protrusion with a V section, one face of which is parallel to the plane of the sections and the other is oblique on this plane, and the lower edge of the panel has a reentrant of suitable shape.

La coopération des surfaces parallèles au plan des profilés de deux panneaux adjacents procure un maintien efficace de la position du profilé extérieur d'un panneau par rapport à celui du panneau adjacent.The cooperation of the surfaces parallel to the plane of the profiles of two adjacent panels provides effective maintenance of the position of the outer profile of a panel relative to that of the adjacent panel.

La coopération des surfaces obliques parallèles pousse les surfaces parallèles au plan des faces principales à rester en contact l'une avec l'autre lorsque les panneaux sont poussés l'un sur l'autre par exemple sous l'effet du poids du profilé supérieur. L'angle au sommet du V ne doit pas être trop faible, afin d'éviter un risque de coincement du saillant dans le rentrant, et d'assurer un bon remplissage du saillant, notamment au cas où l'âme est en mousse formée sur place. L'angle au sommet de V ne doit pas être trop proche de 90°, pour que le frottement n'empêche pas le glissement des surfaces obliques l'une sur l'autre sous l'effet du poids des panneaux. En outre, un angle au sommet trop grand augmente inutilement l'épaisseur du panneau. A l'intérieur d'une fourchette de 10 à 80°, des valeurs de 20 à 35° sont préférées.The cooperation of the parallel oblique surfaces pushes the surfaces parallel to the plane of the main faces to remain in contact with each other when the panels are pushed one on the other for example under the effect of the weight of the upper profile. The angle at the top of the V must not be too small, in order to avoid a risk of jamming of the salient in the reentrant, and to ensure a good filling of the salient, in particular in the case where the core is made of foam formed on square. The angle at the top of V must not be too close to 90 °, so that friction does not prevent the sliding of the oblique surfaces one on the other under the effect of the weight of the panels. In addition, too large an angle at the apex unnecessarily increases the thickness of the panel. Within a range of 10 to 80 °, values of 20 to 35 ° are preferred.

La position particulière de la partie d'appui procure un contact à la fois coulissant et étanche entre panneaux adjacents sans nuire au bon maintien de ceux-ci, et sans risquer de déformations locales inesthétiques au voisinage des pièces de fixation.The particular position of the support part provides both sliding and sealed contact between adjacent panels without adversely affecting the proper maintenance thereof, and without risking unsightly local deformations in the vicinity of the fasteners.

Avantageusement, la face du premier rentrant du bord inférieur qui est opposée au premier saillant comporte une partie d'appui à peu près parallèle au plan des faces principales prévues sur le profilé extérieur, et sur laquelle vient en contact une partie d'orientation analogue de la pièce de fixation.Advantageously, the face of the first re-entrant from the lower edge which is opposite to the first projection has a support part roughly parallel to the plane of the main faces provided on the external profile, and on which comes a part of similar orientation of the fixing part.

Avantageusement aussi, la courbure d'ensemble du fond du premier rentrant du bord inférieur est plus forte que celle du sommet du premier saillant du bord supérieur, si bien que, lorsque les faces dudit saillant et dudit rentrant sont en contact, il existe un espace de décompression entre ledit fond et ledit sommet.Advantageously also, the overall curvature of the bottom of the first reentrant of the lower edge is greater than that of the top of the first protrusion of the upper edge, so that, when the faces of said protruding and said reentrant are in contact, there is a space decompression between said bottom and said top.

Un tel espace de décompression est utile pour limiter les infiltrations d'eau à travers le joint, ainsi que cela est bien connu des spécialistes.Such a decompression space is useful for limiting the infiltration of water through the joint, as is well known to specialists.

L'invention va maintenant être décrite de façon plus détaillée à l'aide d'un exemple pratique illustré à l'aide des dessins parmi lesquels :The invention will now be described in more detail with the aid of a practical example illustrated with the aid of the drawings among which:

Figure 1 est une coupe verticale de la zone de la jonction entre deux panneaux sandwich conformes à l'invention, superposés pour constituer une paroi verticale, la coupe étant faite en dehors d'une pièce de fixation.Figure 1 is a vertical section of the area of the junction between two sandwich panels according to the invention, superimposed to form a vertical wall, the section being made outside of a fixing piece.

Figure 2 est une vue partielle montrant une variante de la figure 1, la coupe traversant une pièce de fixationFigure 2 is a partial view showing a variant of Figure 1, the section through a fastener

La figure 1 montre, en coupe, le bord longitudinal supérieur 1 d'un panneau sandwich 2, associé au bord longitudinal inférieur 3 d'un second panneau sandwich 4 placé au-dessus du premier panneau sandwich. Les deux panneaux sont en appui contre un support vertical 5, de telle façon que les faces principales intérieures 6, 6' des panneaux 2 et 4 sont en appui sur la face avant 7 du support 5 et se trouvent donc dans le même plan. Les deux panneaux sandwich étant de même épaisseur, les faces principales extérieures 8, 8' des panneaux 2 et 4 sont également sensiblement dans le même plan vertical.FIG. 1 shows, in section, the upper longitudinal edge 1 of a sandwich panel 2, associated with the lower longitudinal edge 3 of a second sandwich panel 4 placed above the first sandwich panel. Both panels are in abutment against a vertical support 5, such that the main interior faces 6, 6 ′ of the panels 2 and 4 are in abutment on the front face 7 of the support 5 and are therefore in the same plane. The two sandwich panels being of the same thickness, the main external faces 8, 8 ′ of the panels 2 and 4 are also substantially in the same vertical plane.

L'homme de métier comprendra que la même figure est utilisable au cas où l'invention est appliquée à une paroi non verticale, en particulier une toiture, ou dans le cas où les supports 5 ne sont pas verticaux.Those skilled in the art will understand that the same figure can be used in the case where the invention is applied to a non-vertical wall, in particular a roof, or in the case where the supports 5 are not vertical.

Chacun des panneaux est constitué par un profilé 9, 10, qui constitue la face principale intérieure, 6, 6', par un profilé extérieur 11, 12, qui constitue la face extérieure 8, 8', et une âme en mousse 13 qui relie et maintient ensemble les profilés extérieurs et intérieurs de chaque panneau sandwich. Un garnissage en une matière autre qu'une mousse peut, bien entendu, être utilisé.Each of the panels is constituted by a profile 9, 10, which constitutes the main internal face, 6, 6 ', by an external profile 11, 12, which constitutes the external face 8, 8', and a foam core 13 which connects and holds together the exterior and interior profiles of each sandwich panel. A filling of a material other than a foam can, of course, be used.

Le bord longitudinal inférieur 3 présente un premier saillant 14, à faces parallèles, dont une première face est le prolongement de la face principale extérieure 8', et une deuxième face 15 est plus proche de l'intérieur, c'est-à-dire de la face principale intérieure 6' du panneau.The lower longitudinal edge 3 has a first projection 14, with parallel faces, a first face of which is an extension of the main external face 8 ', and a second face 15 is closer to the inside, that is to say of the interior main face 6 ′ of the panel.

La forme du saillant 14, à faces parallèles, lui assure une bonne robustesse et réduit les risques de défauts de remplissage par la mousse. Pour des raisons esthétiques, on peut préférer que la première face de ce saillant soit oblique sur la face principale extérieure, et/ou se raccorde avec cette dernière par un arrondi ou un décrochement, sans sortir de l'invention.The shape of the protrusion 14, with parallel faces, provides it with good robustness and reduces the risks of foam filling faults. For aesthetic reasons, it may be preferable for the first face of this projection to be oblique on the outer main face, and / or to be connected with the latter by a rounding or a recess, without departing from the invention.

Le premier saillant 14 est suivi directement, en direction de l'intérieur, par un premier rentrant 16.The first projection 14 is followed directly, towards the interior, by a first re-entrant 16.

Sur le bord supérieur 1, en face de la partie du bord inférieur 3 qu'on vient de décrire, se trouve un renfoncement 17, suivi immédiatement d'un premier saillant 18. Le premier saillant 14 du bord inférieur 3 avance dans le renfoncement 17 du bord supérieur 1, alors que le premier saillant 18 du bord supérieur 1 pénètre dans le premier rentrant 16 du bord inférieur 3. Le bord supérieur 1 présente une surface 19, plane et parallèle à la face extérieure 8, et qui délimite à la fois le renfoncement 17 et le saillant 18. La distance d entre le plan de la surface 19 et celui de la face extérieure 8 est égale à l'épaisseur du saillant 14. Il en résulte que, quand cette face 19 est en contact avec la face intérieure 15 du saillant 14, les faces extérieures 8 et 8' des deux panneaux sandwich sont maintenues rigoureusement dans le même plan vertical au voisinage de la jonction, ce qui est avantageux du point de vue de l'aspect de l'ensemble.On the upper edge 1, opposite the part of the lower edge 3 that has just been described, is a recess 17, immediately followed by a first projection 18. The first projection 14 of the lower edge 3 advances in the recess 17 of the upper edge 1, while the first projection 18 of the upper edge 1 enters the first reentrant 16 of the lower edge 3. The upper edge 1 has a surface 19, flat and parallel to the outer face 8, and which delimits both the recess 17 and the projection 18. The distance d between the plane of the surface 19 and that of the outer face 8 is equal to the thickness of the projection 14. As a result, when this face 19 is in contact with the inner face 15 of the projection 14, the outer faces 8 and 8 ′ of the two sandwich panels are held strictly in the same vertical plane in the vicinity of the junction, which is advantageous from the point of view of the appearance of the assembly .

L'épaisseur d du saillant 14 est choisie assez grande pour éviter le risque d'un mauvais remplissage de ce résultat par la mousse.The thickness d of the projection 14 is chosen to be large enough to avoid the risk of improper filling of this result with the foam.

Le rentrant 16 a une section en V. Il est limité d'un côté par le bord 15 du saillant 14, et de l'autre côté par une surface oblique 20, qui fait avec le plan de la face 15 un angle A d'environ 25°. Le saillant correspondant 18 a une section correspondante en V, il est limité d'une part par la face 19, comme il a été dit plus tôt, et de l'autre côté par une surface oblique 21 qui fait le même angle A avec la face 19.The reentrant 16 has a V-shaped section. It is limited on one side by the edge 15 of the protrusion 14, and on the other side by an oblique surface 20, which forms with the plane of the face 15 an angle A of about 25 °. The corresponding projection 18 has a corresponding V-shaped section, it is limited on the one hand by the face 19, as it was said earlier, and on the other hand by an oblique surface 21 which makes the same angle A with the face 19.

Le fond 22 du rentrant 16 est, en coupe, en arc de cercle, avec un rayon de courbure inférieur à celui de l'extrémité 23 de l'extrémité du saillant 18. Il en résulte que ce saillant peut pénétrer librement à l'intérieur du rentrant, et être en contact avec lui par ses deux faces 19, 21. On observera que les formes du fond du rentrant 16 et de l'extrémité du saillant 18 pourraient être différentes, par exemple polygonales, l'essentiel étant que le saillant puisse s'enfoncer librement dans le rentrant jusqu'à venir en contact avec lui par ses deux faces. On assure ainsi un contact étanche entre les deux bords 1 et 3 des profilés. De plus, le vide existant entre le fond du rentrant et l'extrémité du saillant constitue un espace de décompression qui s'oppose efficacement au passage d'humidité par capillarité, ainsi que cela est connu des hommes du métier.The bottom 22 of the reentrant 16 is, in section, in an arc of a circle, with a radius of curvature less than that of the end 23 of the end of the projection 18. As a result, this projection can penetrate freely inside of the reentrant, and being in contact with it by its two faces 19, 21. It will be observed that the shapes of the bottom of the reentrant 16 and of the end of the projection 18 could be different, for example polygonal, the main thing being that the projection can sink freely into the reentrant until it comes into contact with it by its two faces. This ensures a tight contact between the two edges 1 and 3 of the profiles. In addition, the vacuum existing between the bottom of the reentrant and the end of the projection constitutes a decompression space which effectively opposes the passage of moisture by capillary action, as is known to those skilled in the art.

Selon une variante un peu moins satisfaisante du point de vue de l'étanchéité, mais plus facile à réaliser, la surface 21 fait avec la surface 19 un angle qui est un peu inférieur à A. Le contact entre les panneaux se fait alors selon une ligne, génératrice ou arête, située au niveau de l'extrémité 23.According to a variant which is a little less satisfactory from the point of view of sealing, but easier to produce, the surface 21 makes an angle with the surface 19 which is a little less than A. The contact between the panels is then made according to a line, generator or edge, located at the end 23.

La valeur de l'angle A peut varier dans certaines limites. Cependant, si l'angle A est trop petit, on risque un coincement du saillant 18 dans le rentrant 16, ce qui serait de nature à entraîner l'apparition de contraintes, engendrant des déformations, sous l'effet de sollicitations extérieures telles que les variations de température ou l'action du vent. D'un autre côté, si l'angle A est trop proche de 90°, le frottement entre les surfaces obliques 20, 21 risque d'être trop fort pour que le poids du panneau sandwich supérieur amène, par glissement, les surfaces parallèles 19 et 15 du renfoncement et du saillant à être toujours en contact. Cela réduirait l'étanchéité, et aboutirait à un écart disgracieux entre les plans des faces extérieures 8 et 8'. Les limites de 10 et 80°, et de 20 et 35° indiquées plus haut pour l'angle A doivent évidemment varier selon la nature du matériau, et plus précisément les coefficients de frottement qui résultent, après un certain usage, de l'environnement et des conditions climatiques.The value of the angle A can vary within certain limits. However, if the angle A is too small, there is a risk of jamming of the protrusion 18 in the reentrant 16, which would be likely to cause the appearance of stresses, causing deformations, under the effect of external stresses such as temperature variations or wind action. On the other hand, if the angle A is too close to 90 °, the friction between the oblique surfaces 20, 21 risks being too strong for the weight of the upper sandwich panel to bring, by sliding, the parallel surfaces 19 and 15 of the recess and the salient to be always in contact. This would reduce the seal, and lead to an unsightly gap between the planes of the outer faces 8 and 8 '. The limits of 10 and 80 °, and of 20 and 35 ° indicated above for the angle A must obviously vary according to the nature of the material, and more precisely the coefficients of friction which result, after a certain use, from the environment and climatic conditions.

La surface oblique 20 se raccorde, en allant vers l'intérieur et vers le bas, à un deuxième renfoncement 24, délimité par une deuxième surface oblique 25, qui fait avec le plan des faces extérieures un angle supérieur à l'angle A, et une deuxième face 26, à peu près parallèle au plan desdites faces extérieures. Vis-à-vis du renfoncement 24, la paroi oblique 21 du saillant 18 se prolonge sans changer de direction. Il en résulte la formation d'un espace 27 entre les deux surfaces. Cet espace 27 a deux fonctions : il constitue un deuxième espace de décompression, mais surtout, il sert de logement à l'extrémité 28 d'une ferrure de maintien 29. Cette ferrure de maintien 29 est fixée au support 5 par l'intermédiaire d'un boulon 30, comme on le décrira plus loin. L'extrémité 28 comprend une partie sensiblement verticale, qui vient en appui contre la paroi à peu près verticale 26 du renfoncement 24. Comme cette face 26 est formée par pliage du profilé extérieur 8', on voit que, au cas où une force extérieure, par exemple celle du vent, tendrait à pousser le panneau sandwich 4 vers l'extérieur, en l'écartant du support 5, ce panneau serait maintenu par la ferrure de maintien agissant sur le profilé extérieur, sans risque de voir celui-ci se séparer de l'âme 13, comme cela se produirait si la ferrure de maintien 29 agissait sur le profilé intérieur.The oblique surface 20 is connected, going inwards and downwards, to a second recess 24, delimited by a second oblique surface 25, which forms with the plane of the external faces an angle greater than the angle A, and a second face 26, roughly parallel to the plane of said outer faces. Opposite the recess 24, the oblique wall 21 of the projection 18 extends without changing direction. This results in the formation of a space 27 between the two surfaces. This space 27 has two functions: it constitutes a second decompression space, but above all, it serves as a housing at the end 28 of a retaining fitting 29. This retaining fitting 29 is fixed to the support 5 by means of a bolt 30, as will be described later. The end 28 comprises a substantially vertical part, which abuts against the roughly vertical wall 26 of the recess 24. As this face 26 is formed by folding the external profile 8 ', it can be seen that, in the event that an external force , for example that of the wind, would tend to push the sandwich panel 4 outwards, away from the support 5, this panel would be held by the retaining fitting acting on the external profile, without the risk of seeing it separate from the core 13, as would happen if the retaining fitting 29 acted on the inner profile.

Sur la figure 1, les surfaces 26 et 28 sont à peu près verticales. L'homme de métier comprendra que, pour que le résultat favorable ci-dessus soit obtenu, il suffit que ces surfaces fassent avec la verticale un angle supérieur à leur angle de frottement. En particulier, si l'angle A est inférieur à cet angle de frottement, la surface 26 pourra être parallèle à la surface 20 ou prolongée, comme cela est montré à la figure 2.In FIG. 1, the surfaces 26 and 28 are approximately vertical. Those skilled in the art will understand that, for the above favorable result to be obtained, it is sufficient for these surfaces to make an angle with the vertical greater than their friction angle. In particular, if the angle A is less than this friction angle, the surface 26 may be parallel to the surface 20 or extended, as shown in FIG. 2.

La face 26 du renfoncement 24 n'est pas nécessairement exactement verticale, de même que l'extrémité 28 de la ferrure de maintien 29. Il est cependant nécessaire qu'elle fasse avec la verticale un angle suffisamment faible pour que, sous l'influence d'une sollicitation horizontale, le panneau sandwich 4 n'ait pas tendance à se soulever. Là encore, il est nécessaire de considérer les coefficients de frottement du matériau de la surface 26 et de la ferrure de maintien 29.The face 26 of the recess 24 is not necessarily exactly vertical, as is the end 28 of the retaining fitting 29. It is however necessary for it to make a sufficiently small angle with the vertical so that, under the influence from a horizontal stress, the sandwich panel 4 does not tend to lift. Here again, it is necessary to consider the coefficients of friction of the material of the surface 26 and of the retaining fitting 29.

On peut aussi prévoir que la face 26, et l'extrémité 28, sont légèrement obliques descendant vers l'extérieur de façon assez faible pour ne pas risquer de défauts de remplissage par la mousse.One can also provide that the face 26, and the end 28, are slightly oblique descending towards the outside in a sufficiently small way so as not to risk filling faults with the foam.

Les dimensions du renfoncement 24 doivent, bien évidemment, être telles que la ferrure de maintien 29 puisse passer dans le joint entre les deux panneaux sandwich 2 et 4.The dimensions of the recess 24 must, of course, be such that the retaining fitting 29 can pass through the joint between the two sandwich panels 2 and 4.

Au-delà de l'espace 27, l'extrémité du profilé 8' présente une partie sensiblement horizontale 31, suivie d'une partie 32 repliée vers l'intérieur du panneau sandwich, et qui est destinée à assurer un bon ancrage du profilé 3 dans la mousse 13. La surface oblique 21 du bord supérieur 1 se raccorde, quant à elle, à une surface horizontale 33, prolongée par un repli 34, dirigé vers l'intérieur du panneau sandwich 2, et destiné lui-aussi à assurer un bon ancrage dans la mousse qui forme l'âme de ce profilé. Entre les parties horizontales 31 et 33 est intercalé un joint d'étanchéité en élastomère 35. A l'endroit des ferrures de maintien 29, celles-ci déforment légèrement le joint 35 pour atteindre l'espace 27. La légère perte d'étanchéité qui en résulte est acceptable, étant donné qu'une étanchéité convenable est déjà assurée par la coopération du saillant 18 avec le rentrant 16.Beyond the space 27, the end of the profile 8 'has a substantially horizontal part 31, followed by a part 32 folded inwards from the sandwich panel, and which is intended to ensure good anchoring of the profile 3 in the foam 13. The oblique surface 21 of the upper edge 1 is connected, for its part, to a horizontal surface 33, extended by a fold 34, directed towards the inside of the sandwich panel 2, and also intended to ensure a good anchoring in the foam which forms the core of this profile. Between the horizontal parts 31 and 33 is interposed an elastomeric seal 35. At the location of the retaining fittings 29, these slightly deform the seal 35 to reach the space 27. The slight loss of seal which the result is acceptable, given that a suitable seal is already ensured by the cooperation of the projection 18 with the reentrant 16.

Une amélioration complémentaire peut être obtenue avec un joint de matière souple posé ou collé sur la ferrure de maintien 29.A further improvement can be obtained with a flexible material seal placed or glued to the retaining fitting 29.

On va maintenant décrire les bords des profilés intérieurs 9 et 10. Le bord supérieur du profilé 9 comporte, d'abord, en partant de sa face interne 6, en contact avec le support 5, un saillant 36, dirigé vers le haut, et sur lequel vient en appui une surface horizontale 37 de la ferrure de maintien 29. L'intérêt de cette disposition réside dans le fait que le panneau sandwich 2 ne peut se soulever sous l'effet d'une force extérieure. Le saillant 36 est limité, sur son bord opposé à la face intérieure 6 par une surface oblique 38, qui fait, avec le plan vertical, un angle B de l'ordre de 25°. A la surface 38 fait suite une face 39 horizontale, qui se trouve dans le même plan que la face horizontale 33 du profilé extérieur 11, et qui supporte avec cette dernière le joint d'étanchéité en élastomère 35. Le bord du profilé 9 se prolonge par un rentrant 40 qui pénètre dans la masse de mousse 13, afin d'assurer son ancrage.We will now describe the edges of the internal sections 9 and 10. The upper edge of the section 9 comprises, first, starting from its internal face 6, in contact with the support 5, a projection 36, directed upwards, and on which bears a horizontal surface 37 of the retaining fitting 29. The advantage of this arrangement lies in the fact that the sandwich panel 2 cannot be lifted under the effect of an external force. The projection 36 is limited, on its edge opposite to the inner face 6 by an oblique surface 38, which makes, with the vertical plane, an angle B of the order of 25 °. On the surface 38 follows a horizontal face 39, which lies in the same plane as the horizontal face 33 of the external profile 11, and which supports with the latter the joint sealing elastomer 35. The edge of the profile 9 is extended by a re-entrant 40 which penetrates into the mass of foam 13, to ensure its anchoring.

On notera que le saillant 36 s'étend vers le haut à peu près à la même hauteur que le saillant 18. Cela assure une forme compacte aux bords des panneaux. Il est important que le saillant 18 ne s'étende pas vers le haut au-delà du niveau du boulon 30, mais s'arrête plus bas, de façon à permettre un passage facile d'un outil de serrage de ce boulon 30.It will be noted that the projection 36 extends upwards at approximately the same height as the projection 18. This ensures a compact shape at the edges of the panels. It is important that the projection 18 does not extend upwards beyond the level of the bolt 30, but stops lower, so as to allow easy passage of a tool for tightening this bolt 30.

Le bord inférieur du profilé 10 présente d'abord, en partant de sa face intérieure 6', un troisième renfoncement 41, dont la seule fonction est de servir de logement à la tête du boulon 30. A ce renfoncement fait suite une surface oblique 42, qui fait avec la verticale un angle sensiblement égal à l'angle B, et qui se raccorde à un rentrant 43, qui pénètre, comme le rentrant 32, dans la masse de mousse 13 afin d'assurer son ancrage.The lower edge of the profile 10 first presents, starting from its inner face 6 ′, a third recess 41, the sole function of which is to serve as a housing for the head of the bolt 30. This recess is followed by an oblique surface 42 , which makes an angle with the vertical substantially equal to the angle B, and which is connected to a reentrant 43, which penetrates, like reentrant 32, into the mass of foam 13 in order to ensure its anchoring.

La ferrure de maintien 29 présente, à partir du boulon 30, une partie plane verticale 44, en appui sur le support 5, suivie de la partie horizontale 37 mentionnée plus haut, puis d'une partie oblique 45, qui fait avec la verticale le même angle B que les faces 38 et 42 prévues sur les profilés 9 et 10, et est située entre ces deux faces. La ferrure de maintien se prolonge ensuite par une partie horizontale 46, qui vient déformer le joint d'étanchéité 35, pour se raccorder à la partie verticale 28 décrite plus haut.The retaining fitting 29 has, from the bolt 30, a vertical flat part 44, bearing on the support 5, followed by the horizontal part 37 mentioned above, then by an oblique part 45, which makes the vertical with the same angle B as the faces 38 and 42 provided on the sections 9 and 10, and is located between these two faces. The retaining fitting is then extended by a horizontal part 46, which deforms the seal 35, to be connected to the vertical part 28 described above.

On peut constater que le panneau sandwich supérieur 4 repose sur le panneau sandwich inférieur 2 directement par l'intermédiaire du rentrant 16 et du saillant 18.It can be seen that the upper sandwich panel 4 rests on the lower sandwich panel 2 directly by means of the re-entrant 16 and the projection 18.

Les surfaces obliques 38, 42, 45 coopèrent pour constituer, avec les surfaces obliques 20-21, dirigées en sens opposé, une liaison par saillant et rentrant complémentaire. Cette liaison complémentaire ne se présente qu'à l'endroit des ferrures de maintien 29. Entre deux ferrures de maintien, les surfaces obliques 38, 42 des deux panneaux 2 et 4 sont séparées par un intervalle égal à l'épaisseur d'une ferrure de maintien 29.The oblique surfaces 38, 42, 45 cooperate to constitute, with the oblique surfaces 20-21, directed in opposite directions, a complementary projecting and re-entrant connection. This complementary connection only occurs at the location of the holding fittings 29. Between two holding fittings, the oblique surfaces 38, 42 of the two panels 2 and 4 are separated by an interval equal to the thickness of a retaining fitting 29.

Les profilés intérieurs 9, 10 sont retenus sur le support 5 par coopération de leurs saillants 36 avec les surfaces horizontales 37 des ferrures de maintien 29. Ils peuvent donc subir une déformation par dilatation en cas de températures élevées. Toutefois, ces déformations éventuelles sont absorbées par la mousse 13, et ne sont pas transmises aux profilés extérieurs 11, 12 qui peuvent se dilater librement.The internal sections 9, 10 are retained on the support 5 by cooperation of their projections 36 with the horizontal surfaces 37 of the retaining fittings 29. They can therefore undergo deformation by expansion in the event of high temperatures. However, these possible deformations are absorbed by the foam 13, and are not transmitted to the external sections 11, 12 which can expand freely.

Une feuille d'étanchéité 47 adhérente aux extrémités des profilés extérieur 12 et intérieur 10 du bord inférieur empêche toute pénétration d'humidité dans la masse de mousse 13. En ce qui concerne le bord supérieur, cette fonction est assurée par le joint d'étanchéité en caoutchouc 35, qui assure donc une double fonction, d'empêcher la pénétration de l'air et de l'humidité entre l'intérieur et l'extérieur du bâtiment, et empêcher la pénétration de ces mêmes corps à l'intérieur de la masse de mousse 13.A sealing sheet 47 adhering to the ends of the outer 12 and inner 10 profiles of the lower edge prevents any penetration of moisture into the foam mass 13. As regards the upper edge, this function is provided by the seal made of rubber 35, which therefore performs a dual function, of preventing the penetration of air and moisture between the interior and exterior of the building, and preventing the penetration of these same bodies inside the foam mass 13.

On observera que si on désire changer l'épaisseur des panneaux sandwich, il suffit de changer la quantité de mousse 13 qu'ils contiennent, ainsi que la largeur du joint 35 et de la feuille 47, les profilés métalliques restant les mêmes.It will be observed that if it is desired to change the thickness of the sandwich panels, it suffices to change the quantity of foam 13 which they contain, as well as the width of the joint 35 and of the sheet 47, the metal profiles remaining the same.

La figure 2 montre une autre configuration de l'espace 27 et de l'extrémité 28 de la ferrure de maintien 29, avec deux particularités qui ne sont pas forcément liées entre elles.FIG. 2 shows another configuration of the space 27 and of the end 28 of the retaining fitting 29, with two particular features which are not necessarily linked together.

La surface 26 d'appui contre la partie 28 d'extrémité de la ferrure de maintien 29 est directement en prolongement de la surface oblique 20, l'angle A étant inférieur à l'angle de frottement des matériaux dont sont faits le profilé 9 et la ferrure 29. La partie 28 est évidemment parallèle à la surface 20. Cette disposition a l'avantage de la rapprocher du plan de la face extérieure 8'. L'espace 27, destiné à servir de logement à la partie 28 d'extrémité de la ferrure de maintien 29, est obtenu en prévoyant un renfoncement 50 entre la surface oblique 21 du bord supérieur et la partie horizontale 33.The surface 26 bearing against the end portion 28 of the retaining fitting 29 is directly in extension of the oblique surface 20, the angle A being less than the friction angle of the materials from which the profile 9 is made and the fitting 29. The part 28 is obviously parallel to the surface 20. This arrangement has the advantage of bringing it closer to the plane of the external face 8 '. Space 27, intended to serve as accommodation for the party 28 at the end of the retaining fitting 29 is obtained by providing a recess 50 between the oblique surface 21 of the upper edge and the horizontal part 33.

Le fond 51 du renfoncement 50 est à peu près parallèle à la partie d'extrémité 28, mais ne coopère pas nécessairement avec elle. Il se raccorde à la surface oblique 21 par un raccordement 52, oblique sur la verticale et dirigé vers l'intérieur et vers le haut. L'extrémité 53 de la ferrure de maintien 28 vient en appui sur le raccordement 52. Elle est légèrement poussée contre lui par la force élastique du joint 35, comprimé par la ferrure 29 comme cela a été dit plus haut.The bottom 51 of the recess 50 is approximately parallel to the end portion 28, but does not necessarily cooperate with it. It is connected to the oblique surface 21 by a connection 52, oblique on the vertical and directed inwards and upwards. The end 53 of the retaining fitting 28 bears on the connection 52. It is slightly pushed against it by the elastic force of the seal 35, compressed by the fitting 29 as has been said above.

Lors du montage, après avoir mis en place le premier panneau sandwich 2 contre le support 5, on place la ferrure de maintien 29 en engageant son extrémité 53 contre le raccordement 52, puis en la faisant pivoter autour du point de contact jusqu'à ce que sa partie 45 repose sur la partie 38 du panneau 2. La position de la ferrure de maintien est alors sa position finale, et il n'y a plus de difficulté pour sa fixation précise à l'aide du boulon 30. Le panneau sandwich suivant 4 est alors placé sur le panneau sandwich 2 et les ferrures 29 et se trouve immédiatement dans la position convenable.During assembly, after having put in place the first sandwich panel 2 against the support 5, the retaining fitting 29 is placed by engaging its end 53 against the connection 52, then by pivoting it around the point of contact until that its part 45 rests on part 38 of the panel 2. The position of the retaining fitting is then its final position, and there is no longer any difficulty in fixing it precisely using the bolt 30. The sandwich panel next 4 is then placed on the sandwich panel 2 and the fittings 29 and is immediately in the suitable position.

Dans le cas d'une disposition conforme à la figure 1 le renfoncement 50 et le raccordement 52 n'existent pas, mais, pour pouvoir faire le montage de manière analogue, il suffit de prévoir, dans la surface 21, une rainure dont le bord supérieur remplira le même rôle que le raccordement 52.In the case of an arrangement in accordance with FIG. 1, the recess 50 and the connection 52 do not exist, but, in order to be able to assemble in a similar manner, it suffices to provide, in the surface 21, a groove whose edge higher will fulfill the same role as connection 52.

On notera que ce mode de montage n'engendre aucune contrainte sur les profilés, qui ne sont donc pas déformés.It will be noted that this mounting method does not generate any constraint on the profiles, which are therefore not deformed.

Un avantage de l'ensemble selon l'invention réside dans le fait que sa mise en place ne comporte aucune liaison par enclenchement élastique, si bien que les panneaux, et surtout leurs profilés extérieures, ne subissent aucune déformation ou contrainte susceptible d'altérer leur planéité, et donc leur aspect.An advantage of the assembly according to the invention lies in the fact that its installation does not include any connection by elastic engagement, so that the panels, and especially their external profiles, do not undergo no deformation or stress liable to alter their flatness, and therefore their appearance.

Il en résulte des surfaces particulièrement satisfaisantes du point de vue esthétique, sans diminution des propriétés d'isolation et de la robustesse.This results in particularly satisfactory surfaces from an aesthetic point of view, without reducing the insulation properties and the robustness.
