Description

La présente invention concerne les panneaux à âme isolante prise en sandwich entre deux plaques. De tels panneaux dits « de type sandwich » sont utiles dans le domaine de la construction ou du bâtiment, notamment pour constituer des ouvrants de porte ou encore comme panneaux d'habillage de façade, ces derniers pouvant être des panneaux rapportés pour construire une façade ou sur une façade existante pour rénover celle-ci. Un panneau selon le préambule de la revendication 1 est décrit dans le document US 3 000 144 A .The present invention relates to insulating core panels sandwiched between two plates. Such panels called "sandwich type" are useful in the field of construction or building, including for constituting door openings or as facade cladding panels, the latter can be reported panels to build a facade or on an existing facade to renovate it. A sign according to the preamble of claim 1 is described in the document US 3,000 144 A .

De tels panneaux, notamment lorsqu'ils sont exposés à l'extérieur - ce qui est le cas des panneaux de portes d'entrée extérieures (pavillons ou immeubles) et des panneaux d'habillage de façade - sont soumis à des différences de dilatation entre au moins la plaque extérieure et l'âme isolante. Un tel effet, dit « effet bilame », conduit à des déformations et cintrages des panneaux, à la fois inesthétiques et source d'un mauvais fonctionnement, gênant ou même pouvant aller jusqu'à exiger un remplacement du panneau, par exemple si la fermeture d'une porte est empêchée.Such signs, especially when exposed outdoors - such as external entrance door panels (pavilions or buildings) and facade cladding panels - are subject to differences in expansion between at least the outer plate and the insulating core. Such an effect, called "bimetallic effect", leads to deformations and bending of the panels, both unsightly and source of a malfunction, annoying or even up to require replacement of the panel, for example if the closure a door is prevented.

Le problème posé est résolu selon l'invention par la modification de la surface de l'âme en contact avec au moins la plaque pour laquelle se pose le problème de l'effet bilame, à savoir au moins la face de la plaque extérieure dans le cas d'un ouvrant ou d'un panneau d'habillage de façade.The problem is solved according to the invention by modifying the surface of the core in contact with at least the plate for which there is the problem of the bimetallic effect, namely at least the face of the outer plate in the case of an opening or facade cladding panel.

Cette modification de surface consiste, selon l'invention, en la formation de sillons ou entailles généralement perpendiculaires au plan de la surface de l'âme qui viendra en application contre la face interne de la plaque en question, créant ainsi des plots de matière aptes à subir de légers déplacements latéraux devant compenser l'effet bilame par régions individualisées.This surface modification consists, according to the invention, in the formation of grooves or notches generally perpendicular to the plane of the surface of the core which will come into application against the internal face of the plate in question, thus creating pads of material able to undergo slight lateral movements to compensate the bimetallic effect in individualized regions.

L'idée est en effet de diviser la région globale sur laquelle se produit l'effet bilame en une succession de petites régions séparées les unes des autres sur chacune desquelles l'effet pourra avoir lieu dans une toute petite mesure, ce petit effet ayant un impact - non perceptible, voire nul - seulement sur la toute petite région en question au lieu d'un effet global et donc visible sur l'ensemble.The idea is in fact to divide the global region on which the bimetallic effect occurs into a succession of small regions separated from each other on each of which the effect can take place in a very small measure, this small effect having a impact - not noticeable or even nil - only on the very small area in question instead of a global effect and therefore visible on the whole.

L'invention a pour objet un panneau de type sandwich utile en particulier dans le domaine de la construction et du bâtiment, consistant en une âme en matériau isolant prise en sandwich entre deux plaques d'un matériau rigide avec lesquelles ladite âme est rendue solidaire, les matériaux desdites plaques présentant un comportement de dilatation différent de celui de ladite âme, caractérisé par le fait que, sur au moins une partie d'au moins une surface de ladite âme en contact avec une plaque sont pratiqués des évidements de types sillons ou rainures créant des régions d'âme séparées les unes des autres, aptes à subir, sous l'effet de la dilatation, de légers déplacements latéraux indépendants, le matériau d'âme étant choisi pour autoriser de tels déplacements, la solidarisation de l'âme avec la plaque voisine au niveau desdites régions étant effectuée sur au moins une partie de celles-ci et étant agencée pour ne pas faire obstacle aux déplacements précités.The invention relates to a sandwich type panel useful in particular in the field of construction and building, consisting of a core of insulating material sandwiched between two plates of a rigid material with which said core is made integral, the materials of said plates having a behavior of expansion different from that of said core, characterized in that, on at least a part of at least one surface of said core in contact with a plate, groove or groove-type recesses are made; creating core regions separated from each other, able to undergo, under the effect of the expansion, slight independent lateral movements, the core material being chosen to allow such displacements, the joining of the soul with the neighboring plate at said regions being made on at least a portion thereof and being arranged not to hinder the movements cited.

L'âme peut notamment être une âme en mousse, telle qu'une mousse dure, par exemple de polyuréthane ou de polystyrène. Les plaques peuvent notamment être des plaques métalliques, par exemple en acier ou en aluminium, ou en matière plastique telle que le PVC, ou en bois.The core may especially be a foam core, such as a hard foam, for example polyurethane or polystyrene. The plates may in particular be metal plates, for example steel or aluminum, or plastic material such as PVC, or wood.

Des régions d'âme séparées peuvent être créées sur au moins une partie de la surface de l'âme en contact avec la plaque destinée à être tournée vers l'extérieur en position d'utilisation.Separate core regions may be created on at least a portion of the web surface in contact with the plate to be turned outward in the use position.

La solidarisation de l'âme avec la plaque voisine au niveau desdites régions peut être effectuée par des points ou zones de collage régulièrement ou sensiblement régulièrement répartis sur tout ou partie desdites régions, la colle étant choisie pour autoriser les déplacements sous l'effet de la dilatation tout en assurant la tenue dudit panneau, la solidarisation de l'âme avec la plaque voisine dans les parties d'âme ne comportant pas les régions indépendantes pouvant être avantageusement effectuée par une couche de colle continue.The solidarization of the core with the adjacent plate at said regions may be effected by points or bonding regions regularly or substantially regularly distributed over all or part of said regions, the adhesive being chosen to allow displacements under the effect of the dilation while ensuring the holding of said panel, the joining of the core with the adjacent plate in the core portions not comprising the independent regions can be advantageously performed by a continuous adhesive layer.

Les points ou zones de collage peuvent être formés par des pastilles de colle appliquées sur les surfaces desdites régions indépendantes, ou peuvent être obtenus par de la colle introduite dans des trous borgnes ou traversants pratiqués dans l'âme.The points or bonding areas may be formed by adhesive pellets applied to the surfaces of said independent regions, or may be obtained by glue introduced into blind or through holes made in the core.

On peut ainsi mentionner des trous borgnes d'une profondeur d'environ 10 mm pour une âme d'environ 70 mm d'épaisseur.We can thus mention blind holes with a depth of about 10 mm for a core of about 70 mm thick.

Les sillons ou rainures peuvent être perpendiculaires à la surface de l'âme dans laquelle ils sont pratiqués et de profondeur suffisante pour autoriser les déplacements latéraux indépendants sans nuire aux résistances mécanique et thermique de l'âme.The grooves or grooves may be perpendicular to the surface of the core in which they are made and of sufficient depth to allow independent lateral movements without harming the mechanical and thermal resistance of the core.

Les régions indépendantes peuvent être formées par un quadrillage de la surface de l'âme par les sillons, ménageant des régions en forme de plots de section carrée ou rectangulaire, les sillons étant constitués par des sillons longitudinaux disposés selon la longueur de la plaque et par des sillons transversaux disposés selon la largeur de la plaque, les zones de collage étant prévues dans la zone centrale de surface d'au moins une partie des plots.The independent regions can be formed by a grid of the surface of the soul by the grooves, leaving regions in the form of square section studs or rectangular, the grooves being formed by longitudinal grooves arranged along the length of the plate and by transverse grooves arranged along the width of the plate, the bonding areas being provided in the central surface area of at least a portion of the pads.

On prévoit avantageusement que chaque plot présente une zone de collage. Dans le cas où seule une partie des plots présente une zone de collage, ces zones de collage sont avantageusement réparties sur l'ensemble des plots.Advantageously, each stud has a bonding zone. In the case where only a portion of the pads has a bonding area, these bonding areas are advantageously distributed over all the pads.

En variante, les régions indépendantes peuvent être formées par un réseau d'évidements ménageant des régions en forme de plots de section cylindrique, les zones de collage étant prévues dans la zone centrale de surface d'au moins une partie des plots.Alternatively, the independent regions may be formed by a network of recesses forming regions in the form of pads of cylindrical section, the bonding areas being provided in the central surface area of at least a portion of the pads.

De très nombreuses possibilités existent pour la forme de ces plots et leur disposition pour obtenir l'effet attendu selon la forme générale et la structure du panneau final, sachant que la dilatation est généralement la plus grande suivant la plus grande dimension d'une plaque, notamment d'une plaque métallique. Ainsi, la forme des plots n'est pas limitée à celles indiquées ci-dessus ; on pourra former des plots en forme de losange ou en tout autre forme particulière.Numerous possibilities exist for the shape of these studs and their arrangement to obtain the expected effect according to the general shape and the structure of the final panel, knowing that the expansion is generally the largest in the largest dimension of a plate, in particular a metal plate. Thus, the shape of the studs is not limited to those indicated above; diamond-shaped studs or any other particular shape may be formed.

Le panneau peut se présenter sous la forme d'une nappe dans laquelle seront découpés les panneaux sandwich individuels destinés à être posés, le cas échéant après façonnage d'au moins un chant de l'âme pour l'adaptation à la pièce particulière à poser et/ou modification d'au moins une bordure d'au moins une plaque par découpe et/ou pliage pour l'adaptation à la pièce particulière à poser, ou encore se présente sous la forme du panneau de type sandwich individuel destiné à être posé, le cas échéant après façonnage d'au moins un chant de l'âme et/ou modification d'au moins une bordure d'au moins une plaque par découpe et/ou pliage.The panel may be in the form of a sheet in which will be cut the individual sandwich panels to be laid, if necessary after shaping at least one edge of the core for adaptation to the particular room to ask and / or modification of at least one edge of at least one plate by cutting and / or folding to adapt to the particular part to be laid, or is in the form of a panel of the type individual sandwich intended to be laid, if appropriate after forming at least one edge of the core and / or modification of at least one edge of at least one plate by cutting and / or folding.

L'invention a également pour objet un panneau de bâtiment, tel que panneau d'habillage de façade ou ouvrant de menuiserie, constitué à partir d'un panneau de type sandwich tel que défini ci-dessus.The invention also relates to a building panel, such as facade cladding panel or carpentry door, formed from a sandwich panel as defined above.

Les plaques du panneau de type sandwich, disposées en regard avec interposition de l'âme en matériau isolant, peuvent être agencées à leur périphérie pour former une bordure dudit panneau de bâtiment ou pour coopérer avec un cadre périphérique interposé entre elles, notamment pour un ouvrant de menuiserie tel qu'une porte, les régions séparées de l'âme étant tournées vers la plaque extérieure, des moyens étant prévus pour ne pas empêcher des mouvements de déplacement de ladite plaque extérieure dans son plan ou sensiblement dans son plan, et, dans le cas où un cadre est prévu, pour permettre de manière indépendante les mouvements de déplacement du cadre suivant un plan parallèle ou sensiblement parallèle au précédent si les coefficients de dilatation de la plaque extérieure et du cadre sont différents.The plates of the sandwich-type panel, disposed facing the interposition of the core of insulating material, can be arranged at their periphery to form a border of said building panel or to cooperate with a peripheral frame interposed between them, in particular for an opening carpentry such as a door, the separated regions of the core being turned towards the outer plate, means being provided not to prevent movement movements of said outer plate in its plane or substantially in its plane, and, in the case where a frame is provided, to independently allow movement movements of the frame in a plane parallel or substantially parallel to the previous if the expansion coefficients of the outer plate and the frame are different.

Conformément à un premier mode de réalisation du panneau de bâtiment selon l'invention, le cadre est solidarisé par collage avec la plaque intérieure et n'est pas solidaire de la plaque extérieure, la plaque extérieure pouvant être repliée à sa périphérie pour former un retour venant en appui contre le cadre, une masse de remplissage isolante pouvant être disposée entre le cadre et la plaque extérieure.According to a first embodiment of the building panel according to the invention, the frame is secured by bonding with the inner plate and is not integral with the outer plate, the outer plate can be folded around its periphery to form a return bearing against the frame, an insulating filling mass that can be arranged between the frame and the outer plate.

Conformément à un deuxième mode de réalisation du panneau de bâtiment selon l'invention, le cadre est solidarisé par collage avec la plaque intérieure, un système à chevrons étant interposé entre le cadre et la plaque extérieure pour permettre les déplacements relatifs du cadre et de la plaque extérieure, la plaque extérieure pouvant être repliée le long de ses bords verticaux pour former un retour, fixé au chevron voisin par des goujons ou rivets aptes à se déplacer dans des trous oblongs du chevron afin de permettre le coulissement vertical de la plaque extérieure.According to a second embodiment of the building panel according to the invention, the frame is bonded by bonding with the inner plate, a chevron system being interposed between the frame and the outer plate to allow relative movement of the frame and the outer plate, the outer plate can be folded along its vertical edges to form a return attached to the neighboring chevron by studs or rivets able to move in oblong holes of the chevron to allow vertical sliding of the outer plate.

Conformément à un troisième mode de réalisation du panneau de bâtiment selon l'invention, le cadre est solidarisé par collage avec la plaque intérieure, et que la plaque extérieure est repliée d'équerre pour venir en appui contre le cadre, le retour d'équerre étant fixé à une pièce intérieure, telle qu'une cornière ou une masse de remplissage dure isolante, par des goujons ou rivets aptes à se déplacer dans des trous oblongs de la pièce intérieure, laquelle est solidaire du cadre, afin de permettre le coulissement vertical de la plaque extérieure (103), les trous oblongs pouvant faire partie des boutonnières facilitant la pose de la plaque extérieure (103).According to a third embodiment of the building panel according to the invention, the frame is secured by gluing with the inner plate, and the outer plate is folded square to bear against the frame, the return of squared being attached to an inner part, such as an angle iron or an insulating hard filler, by studs or rivets adapted to move in oblong holes of the inner part, which is secured to the frame, to allow vertical sliding the outer plate (103), the oblong holes being part of the buttonholes facilitating the installation of the outer plate (103).

L'espace entre la plaque, la cornière et le cadre peut être rempli par une mousse, une extension de l'âme ou une mousse en matière plastique rigide isolante.The space between the plate, the angle and the frame can be filled with a foam, an extension of the core or a rigid insulating plastic foam.

On pourra se reporter aux demandes de brevets français 2 927 113 et 2 927 114 pour des exemples de systèmes à chevrons pour de tels dispositifs de compensation des différences de dilatation entre le cadre et les plaques.We can refer to French patent applications 2,927,113 and 2,927,114 for examples of herringbone systems for such devices for compensating for differences in expansion between the frame and the plates.

Si l'on se réfère à la Figure 1, on peut voir que l'on a représenté un morceau d'un panneau sandwich 1 pour le bâtiment constitué par deux plaques de parement 2 et 3 - ou plaque interne 2 et plaque externe 3 si l'on considère le panneau final à l'état monté - entre lesquelles est disposé un bloc central ou âme centrale de matériau isolant 27, très légèrement déformable, tel qu'une mousse dure de polyuréthane. Ces plaques ont généralement la forme de bandes ou nappes rectangulaires allongées qui seront ensuite redécoupées à la demande pour constituer des ouvrants de porte et des panneaux d'habillage de façade. On peut aussi envisager qu'ils soient directement formés dans les dimensions requises pour constituer l'ouvrant de porte ou le panneau d'habillage de façade.If we refer to the Figure 1 it can be seen that there is shown a piece of a sandwich panel 1 for the building consisting of two facing plates 2 and 3 - or inner plate 2 and outer plate 3 if we consider the final panel to the mounted state - between which is disposed a central block or central core of insulating material 27, very slightly deformable, such as a rigid polyurethane foam. These plates are generally in the form of elongated rectangular strips or sheets which will then be cut on demand to form door openings and facade cladding panels. It can also be envisaged that they are directly formed into the dimensions required to constitute the door opening or the facade cladding panel.

Les plaques de parement 2 et 3 sont par exemple en tôle d'aluminium de 1,5 mm d'épaisseur, distants de 80 mm dans l'exemple représenté. Les plaques 2 et 3 pourraient tout aussi bien être en acier, en PVC ou matière plastique similaire ou même en bois.The facing plates 2 and 3 are for example made of aluminum sheet 1.5 mm thick, 80 mm apart in the example shown. Plates 2 and 3 could equally well be steel, PVC or similar plastic material or even wood.

La plaque de parement 3 est destinée à être placée côté extérieur en position d'utilisation, par exemple dans le cas où le panneau sandwich est destiné à former un ouvrant de porte d'entrée ou un panneau d'habillage de façade.The facing plate 3 is intended to be placed on the outside in the position of use, for example in the case where the sandwich panel is intended to form an entrance door opening or facade cladding panel.

Compte tenu de cette disposition de la plaque de parement 3 tournée vers l'extérieur, il se présentera en cours d'utilisation, des différences de dilatation entre ladite plaque de parement 3 et l'âme centrale isolante 27 formée d'un seul bloc, un tel effet étant connu comme étant l'effet bilame.In view of this arrangement of the cladding plate 3 facing outwards, it will present in use, differences in expansion between said cladding plate 3 and the insulating central core 27 formed in one piece, such an effect being known as the bimetallic effect.

Pour résoudre ce problème, des entailles ou sillons 27a sont formés dans la face de l'âme isolante 27 qui est destinée à venir en contact avec la face interne de la plaque de parement 3, perpendiculairement à ladite face et sur une hauteur de l'ordre d'environ un quart à un tiers de l'épaisseur de ladite âme 27.To solve this problem, nicks or grooves 27a are formed in the face of the insulating core 27 which is intended to come into contact with the inner face of the facing plate 3, perpendicular to said face and on a height of about one quarter to one third of the thickness of said core 27.

Ces sillons 27a sont disposés suivant un quadrillage, étant formés par des sillons longitudinaux et des sillons transversaux, parallèles aux bords respectivement longitudinal et transversal de la bande de panneau sandwich 1. On peut, à titre d'exemple, mentionner un quadrillage avec des carreaux de 30 mm de côté.These grooves 27a are arranged in a grid, being formed by longitudinal grooves and transverse grooves, parallel to the longitudinal and transverse edges respectively of the sandwich panel strip 1. It is possible, by way of example, to mention a grid with tiles. 30 mm side.

Sont ainsi constitués sur cette surface de l'âme isolante 27 des "plots" carrés 27b qui, compte tenu de la légère possibilité de déformation de la matière composant l'âme 27, seront aptes à subir de légers déplacements latéraux aussi bien dans le sens de la longueur que dans le sens de la largeur. En effet, la profondeur des sillons 27a sera choisie pour autoriser les déplacements précités sans pour autant nuire aux résistances mécanique et thermique recherchées.Are thus formed on this surface of the insulating core 27 square "pads" 27b which, given the slight possibility of deformation of the material component of the core 27, will be able to undergo slight lateral movements both in the sense of the length only in the sense of the width. Indeed, the depth of the grooves 27a will be chosen to allow the aforementioned displacements without adversely affecting the mechanical and thermal resistance sought.

La plaque de parement externe 3 et l'âme en mousse 27 sont fixées par des points ou pastilles de colle 26a placées au centre d'une partie seulement des plots carrés, ces points ou pastilles de colle étant globalement répartis sur toute la surface. La colle 26a est choisie suffisamment souple pour ne pas empêcher les mouvements recherchés desdits plots 27b.The outer facing plate 3 and the foam core 27 are fixed by dots or glue pellets 26a placed at the center of only a portion of the square studs, these points or glue pellets being generally distributed over the entire surface. The glue 26a is chosen flexible enough not to prevent the desired movements of said pads 27b.

La plaque de parement interne 2 est fixée à l'âme en mousse 27 par une couche de colle continue, comme cela sera décrit dans ce qui suit en référence à la description de l'ouvrant de porte. Cette couche de colle n'est pas visible sur les Figures 1 à 4.The inner cladding plate 2 is fixed to the foam core 27 by a layer of continuous glue, as will be described in the following with reference to the description of the door leaf. This layer of glue is not visible on Figures 1 to 4 .

La Figure 2 représente une variante de réalisation du panneau sandwich de la Figure 1 suivant laquelle des trous traversants 26b ont été pratiqués dans la hauteur de l'âme en mousse 27, ces trous 26b étant pratiqués perpendiculairement aux grandes faces de ladite âme en mousse 27 et débouchant au centre de chaque plot carré 27b. Ces trous 26b, qui sont de relativement petit diamètre, sont destinés à recevoir de la colle. Les plots carrés 27b conserveront leur aptitude à se déplacer légèrement individuellement, compensant l'effet bilame, et une bonne fixation de l'âme en mousse 27 à la plaque de parement intérieure 2 sera réalisée par la colle traversant totalement l'âme en mousse 27.The Figure 2 represents an alternative embodiment of the sandwich panel of the Figure 1 according to which through holes 26b have been made in the height of the foam core 27, these holes 26b being made perpendicularly to the large faces of said foam core 27 and opening at the center of each square stud 27b. These holes 26b, which are of relatively small diameter, are intended to receive glue. The square studs 27b will retain their ability to move slightly individually, compensating for the bimetallic effect, and a good attachment of the foam core 27 to the inner facing plate 2 will be achieved by the glue completely passing through the foam core. .

Si l'on se réfère aux Figures 3 et 4, pour lesquelles les mêmes chiffres de référence ont été utilisés, on peut voir que celles-ci correspondants aux Figures respectivement 1 et 2, à la différence que les plots 27b ne sont plus carrés mais cylindriques, étant formés par enlèvement de matière en 27a à la surface de l'âme 27 destinée à venir en contact avec la plaque de parement extérieure 3. De tels plots cylindriques 27b sont susceptibles de se déplacer dans toutes les directions sous l'effet bilame.If we refer to Figures 3 and 4 , for which the same reference numerals were used, it can be seen that these corresponding to Figures 1 and 2 respectively, with the difference that the pads 27b are no longer square but cylindrical, being formed by removal of material in 27a to the surface of the core 27 intended to come into contact with the outer facing plate 3. Such cylindrical studs 27b are capable of moving in all directions under the bimetallic effect.

Si l'on se réfère maintenant aux Figures 5, 6 et 7, on peut voir que l'on a désigné par 101 dans son ensemble un ouvrant d'une porte d'entrée, lequel sera décrit dans ce qui suit avec référence à sa position montée verticale, et qui est constitué par une plaque de parement intérieure 102, une plaque de parement extérieure 103 et un cadre d'ouvrant 104 disposé entre les deux en périphérie et collé aux parois internes respectives des plaques intérieure et extérieure 102 et 103 afin de maintenir celles-ci solidaires. Le cadre 104 se compose de deux montants 105 et deux traverses 106.If we now turn to Figures 5 , 6 and 7 it can be seen that 101 has been designated as a whole an opening of an entry door, which will be described in the following with reference to its vertical mounting position, and which is constituted by an inner facing plate 102, an outer facing plate 103 and an opening frame 104 disposed between the two peripherally and glued to the respective inner walls of the inner and outer plates 102 and 103 to maintain them integral. The frame 104 consists of two uprights 105 and two crosspieces 106.

Les plaques 102 et 103 sont par exemple en tôle d'aluminium de 1,5 mm d'épaisseur, distants de 80 mm dans l'exemple représenté (cf plaques 2 et 3 décrites avec référence aux Figures 1 à 4), et les montants 105 et traverses 106, en PVC. Les plaques 102 et 103 pourraient tout aussi bien être en PVC ou matière plastique similaire ou en bois.The plates 102 and 103 are for example made of aluminum sheet 1.5 mm thick, 80 mm apart in the example shown (see plates 2 and 3 described with reference to Figures 1 to 4 ), and the amounts 105 and crosspieces 106, PVC. The plates 102 and 103 could equally well be PVC or similar plastic material or wood.

La plaque de parement intérieure 102 présente, le long de ses bordures verticales latérales, un retour d'équerre vers l'intérieur 118 (Figure 7).The inner cladding plate 102 has, along its lateral vertical edges, a right-angled return towards the inside 118 ( Figure 7 ).

La plaque de parement extérieure 103 présente, le long de ses bordures verticales latérales, un retour d'équerre vers l'intérieur 21 (Figure 7).The outer facing plate 103 has, along its lateral vertical edges, a right angle of return 21 ( Figure 7 ).

Comme on peut le voir sur la Figure 5, la plaque de parement intérieure 102 est plus longue que la plaque de parement extérieure 103 compte tenu de la présence du dispositif de rejet d'eau 125 de seuil fixé à la plaque 103 par des rivets 125a.As can be seen on the Figure 5 , the inner facing plate 102 is longer than the outer facing plate 103 given the presence of the threshold water discharge device 125 fixed to the plate 103 by rivets 125a.

Contre la face interne de la plaque de parement 102, est disposée une couche 126 de colle qui sert au collage des montants 105 et des traverses 106 du cadre d'ouvrant 104. La colle 126 s'applique à l'état liquide et durcit à l'air.Against the inner face of the facing plate 102, there is disposed a layer 126 of glue which serves to bond the uprights 105 and the crosspieces 106 of the sash frame 104. The glue 126 is applied in the liquid state and cures at the air.

Un bloc central de matériau isolant 127, tel qu'une mousse de polyuréthane (cf bloc 27 décrit avec référence aux Figures 1 à 4), remplit des espaces entre les plaques de parement 102 et 103.A central block of insulating material 127, such as a polyurethane foam (see block 27 described with reference to Figures 1 to 4 ), fills spaces between the facing plates 102 and 103.

Si l'on se réfère maintenant aux Figures 5 à 7, on peut voir que les montants 105 et traverses 106 du cadre d'ouvrant 104 sont formés à partir d'un même profilé de forme générale classique comportant une paroi interne 140 destinée à venir en appui contre le bloc 127 de matière isolante, une paroi 141 perpendiculaire à la paroi 140 destinée à venir s'appliquer contre la couche 126 doublant la plaque de parement 102, et une paroi 142, également perpendiculaire à la précédente, destinée à venir s'appliquer contre une couche 126c doublant la plaque de parement 103 dans la région périphérique.If we now turn to Figures 5 to 7 it can be seen that the uprights 105 and crosspieces 106 of the sash frame 104 are formed from the same profile of conventional general shape having an internal wall 140 intended to bear against the block 127 of insulating material, a wall 141 perpendicular to the wall 140 intended to be applied against the layer 126 doubling the facing plate 102, and a wall 142, also perpendicular to the previous one, intended to be applied against a layer 126c doubling the facing plate 103 in the peripheral region.

Les parois 141 et 142 sont, à l'opposé de la paroi 140, réunies par une paroi externe 143 comportant un décrochement d'équerre 144 car les panneaux de parement 102 et 103 ne sont pas de même hauteur (Figure 5) ni de même largeur (Figure 7). Le décrochement 144 forme une glissière 145 de réception d'un joint 146 dont le rôle est indiqué plus loin.The walls 141 and 142 are, opposite the wall 140, joined by an outer wall 143 having a setback 144 because the facing panels 102 and 103 are not the same height ( Figure 5 ) nor of the same width ( Figure 7 ). The recess 144 forms a slide 145 for receiving a seal 146 whose role is indicated below.

Dans le cas de la traverse 106, la partie de joint 146 extérieure à la glissière 143 est destinée à venir s'appliquer par évasement contre la butée 147a du seuil 147 de la porte, que l'on peut voir sur la Figure 5, avec sa semelle 147b s'étendant à la fois sur le rejingot de maçonnerie 148, côté extérieur et sur le sol fini 149, côté intérieur.In the case of the crossmember 106, the joint portion 146 external to the slideway 143 is intended to be applied by flaring against the abutment 147a of the threshold 147 of the door, which can be seen on the Figure 5 , with its sole 147b extending both on the masonry rejingot 148, on the outside and on the finished floor 149, on the inside.

Dans le cas du montant 105, la partie du joint 146 extérieure à la glissière 145, vient s'appliquer par écrasement contre le dormant 150 de la porte comme on peut le voir sur la Figure 7. Le dormant comporte une aile externe 152 entourée par un habillage 153 venant s'appliquer extérieurement contre une isolation (non représentée) et une tapée 154, qui s'étend contre l'isolation jusqu'au tableau fini, étant fixée par vis 156 au dormant 150. Les paumelles 157 sont fixées à la fois contre l'habillage 153 et contre le retour d'équerre 118 de la plaque de parement 102. Un joint 158 porté par le dormant 150 vient s'appliquer contre la plaque de parement 103. Un tel montage ne sera pas expliqué plus en détail car il est classique.In the case of the amount 105, the portion of the seal 146 outside the slide 145, is applied by crushing against the frame 150 of the door as can be seen on the Figure 7 . The frame comprises an outer flange 152 surrounded by a casing 153 which is applied externally against an insulation (not shown) and a tap 154, which extends against the insulation to the finished panel, being fixed by screws 156 to the frame 150. The hinges 157 are fixed both against the cladding 153 and against the right-angle return 118 of the facing plate 102. A seal 158 carried by the frame 150 is pressed against the cladding plate 103. such editing will not be explained in more detail because it is traditional.

La traverse supérieure du dormant de la porte, que l'on peut voir sur la Figure 6, n'a pas été décrite plus en détail car elle est classique.The upper sleeper of the door frame, which can be seen on the Figure 6 , has not been described in more detail because it is traditional.

Le profilé formant les montants 105 et les traverses 106 présente intérieurement différentes parois, les unes parallèles à la paroi 140, et les autres, parallèles aux parois 141 et 142. Cette structure est connue en soi et ne sera pas décrite plus en détail.The profile forming the uprights 105 and crosspieces 106 has internally different walls, some parallel to the wall 140, and the others, parallel to the walls 141 and 142. This structure is known per se and will not be described in more detail.

On peut prévoir, dans les faces externes des parois 141 et 142, lesquelles sont destinées à venir s'appliquer contre une couche 126 ou 126c de colle, des rainures 159 parallèles au plan de la paroi 140, régulièrement espacées, ayant pour but de recevoir la colle de la couche 126 lors du collage et de consolider ainsi la fixation des montants 105 et des traverses 106 aux plaques de parement 102 et 103. Une telle consolidation est prévue par sécurité car l'expérience a montré que la solidité de la fixation est obtenue sans la présence de ces rainures.In the outer faces of the walls 141 and 142, which are intended to be applied against a layer 126 or 126c of glue, grooves 159 are provided which are parallel to the plane of the wall 140, regularly spaced, intended to receive the glue of the layer 126 during bonding and thereby consolidate the attachment of the uprights 105 and crosspieces 106 to the facing plates 102 and 103. Such consolidation is provided for safety because experience has shown that the strength of the attachment is obtained without the presence of these grooves.

Également selon l'invention, est prévu un dispositif destiné à autoriser la différence de dilatation entre la tôle d'aluminium du panneau de parement externe 103 et le PVC composant les montants 105 et traverses 106. A cet effet, la paroi 142 à la structure particulière suivante :

  • Elle est doublée extérieurement par une paroi plus mince ou aile ou lame 142a réunie à la paroi 142 du profilé par des ponts 142b qui s'étendent parallèlement à la paroi 140 et dont la forme est choisie pour pouvoir suivre les mouvements différents du parement 103 et des montants 105/traverses 106 afin de pouvoir autoriser les différences de dilatation indiquées ci-dessus. Ces ponts, régulièrement espacés, ont pour cela une forme en coupe de chevrons dans l'exemple représenté.
Also according to the invention, there is provided a device for allowing the difference in expansion between the aluminum sheet of the outer facing panel 103 and the PVC component amounts 105 and cross 106. For this purpose, the wall 142 to the structure particular following:
  • It is lined externally by a thinner wall or wing or blade 142a joined to the wall 142 of the section by bridges 142b which extend parallel to the wall 140 and whose shape is chosen to be able to follow the different movements of the facing 103 and amounts 105 / cross 106 in order to allow the differences in expansion indicated above. These bridges, regularly spaced, have for this a form in section of chevrons in the example shown.

Dans ces cas, c'est bien entendu la paroi 142a qui porte les rainures 159.In these cases, it is of course the wall 142a which carries the grooves 159.

Par ailleurs, ce dispositif dit "anti-dilatation", destiné à résoudre les problèmes de déformation de la porte dans sa partie extérieure, formé de la paroi externe 142a et des ponts 142b, n'est pas appliqué dans les parties d'angle aux jonctions des montants 105 et des traverses 106, afin de permettre le déplacement relatif nécessaire entre la partie 142a solidaire du panneau de parement 103 et la partie 142 proprement dite en cas de différence de dilatation.Moreover, this so-called "anti-dilatation" device, intended to solve the problems of deformation of the door in its outer part, formed of the external wall 142a and the bridges 142b, is not applied in the corner portions to the junctures amounts 105 and cross members 106, to allow the necessary relative movement between the portion 142a integral with the cladding panel 103 and the portion 142 itself in case of expansion difference.

Également, l'aile 142a et les ponts 142b sont formés dans un profilé indépendant, les ponts 142b étant reliés à une aile 142c, opposée à la précédente et parallèle à celle-ci. Ce profilé indépendant sera alors appliqué contre la face en regard d'un profilé classique formant les montants 105 et les traverses 106, en y étant fixé par des vis ou rivets 142d introduits chacun par un trou traversant 142e formé dans l'aile 142a. Cette variante permet l'utilisation de profilés classiques aussi bien en PVC qu'en aluminium.Also, the wing 142a and the bridges 142b are formed in an independent section, the bridges 142b being connected to a wing 142c, opposite to the previous one and parallel thereto. This independent profile will then be applied against the opposite side of a conventional profile forming the uprights 105 and crosspieces 106, being fixed by screws or rivets 142d each introduced by a through hole 142e formed in the flange 142a. This variant allows the use of conventional profiles in both PVC and aluminum.

Sur les Figures 5 à 8, on peut voir que le bloc 127 est réalisé comme le bloc 27 de la Figure 1, comportant les sillons 127a ménageant les plots 127b. On a également représenté les pastilles de collage 126a.On the Figures 5 to 8 , we can see that block 127 is realized as block 27 of the Figure 1 , including the grooves 127a sparing the pads 127b. The glue pads 126a are also shown.

Sur les Figures 5 à 7, la coopération entre le cadre 104 et la plaque 103, soumise à l'effet bilame, est telle que décrite précédemment. Sur la Figure 8, on a représenté une variante de réalisation, suivant laquelle le bloc 142 à chevrons n'est pas appliqué, l'espace occupé par celui-ci étant remplacé par une extension 127c du bloc de mousse 127. Ceci montre que l'on pourra partir d'un bloc 1 tel que représenté sur les Figures 1 à 4 et adapter ses chants (aussi bien des plaques que de l'âme) pour la mise en place du panneau complet (ouvrant ou panneau d'habillage).On the Figures 5 to 7 , the cooperation between the frame 104 and the plate 103, subjected to the bimetallic effect, is as previously described. On the Figure 8 there is shown an alternative embodiment, according to which the herringbone block 142 is not applied, the space occupied by it being replaced by an extension 127c of the foam block 127. This shows that it will be possible to leave of a block 1 as represented on the Figures 1 to 4 and adapt its songs (both plates and soul) for the installation of the complete panel (opening or panel dressing).

On peut également utiliser, à la place d'une extension proprement dite du bloc de mousse, une plaque rapportée de matériau isolant, par exemple de cette même mousse, ou de matière plastique rigide isolante comme une plaque de polyester obtenue par pultrusion d'une résine de polyester chargée de fibres de verre, ou encore deux plaques adjacentes par leurs chants verticaux de mousse et de matière plastique rigide isolante.It is also possible to use, in place of an actual extension of the foam block, an insert plate of insulating material, for example of this same foam, or of insulating rigid plastic material such as a polyester plate obtained by pultrusion of a polyester resin filled with glass fibers, or two adjacent plates by their vertical edges of foam and insulating rigid plastic material.

Également, on peut voir sur les Figures 7 et 8 que l'on a prévu une fixation du retour 121 respectivement sur le bloc 142 ou sur l'extension 127c (ou sur l'extension formée de plaque(s) rapportée(s)) de l'âme 127 par des rivets 160 traversant le retour 121 en plusieurs emplacements répartis généralement régulièrement sur toute la hauteur du retour 121. Dans ce dernier cas, une cornière 121a est prévue, dont une aile est appliquée contre la traverse 105 et l'autre, contre le retour 121 ; cette cornière 121a assure le guidage vertical de la plaque 103 en cas de dilatation ainsi que le maintien de la mousse 127, des trous oblongs 161 (orientés verticalement en position de montage) étant pratiqués à cet effet dans la partie de la cornière 121a appliquée contre le retour 121, chacun pour le passage d'un rivet 160. Ceci permet d'autoriser la dilatation et de conserver l'effet du quadrillage prévu selon l'invention.Also, we can see on Figures 7 and 8 that a fixing of the return 121 is provided respectively on the block 142 or on the extension 127c (or on the extension formed of plate (s) reported (s)) of the core 127 by rivets 160 traversing the 121 in several locations distributed regularly evenly over the entire height of the return 121. In the latter case, an angle 121a is provided, one wing is applied against the cross 105 and the other against the return 121; this angle 121a ensures the vertical guidance of the plate 103 in case of expansion and the maintenance of the foam 127, oblong holes 161 (oriented vertically in the mounting position) being made for this purpose in the part of the bracket 121a applied against the return 121, each for the passage of a rivet 160. This allows to allow expansion and maintain the effect of the grid provided according to the invention.

Une variante de réalisation de la cornière 121 est représentée sur la Figure 9. Les trous oblongs 161 sont chacun ouverts en partie haute dans la position de montage suivant une ouverture 161a débouchant horizontalement dans la bordure libre de la cornière 121a. Sont ainsi constituées ce que l'on appelle des boutonnières qui facilitent le montage de la plaque 103. A cet effet, on vient mettre en place des rivets ou goujons à sertir 160 dans le retour 121 aux différentes hauteurs voulues, ces rivets ou goujons 160 étant avantageusement choisis pour que leurs têtes soient noyées dans la tôle du retour 121, leurs tiges faisant saillie vers l'intérieur. Au moment du montage, on fixe la cornière 121a avec ses boutonnières dans la position de la Figure 9, et on vient rapporter la plaque extérieure 103 sur l'âme 121 en faisant entrer horizontalement les tiges des rivets ou goujons 160 dans les ouvertures correspondantes 161a des boutonnières, puis on fait descendre la plaque 103, les rivets ou goujons 160 descendant les parties oblongues 161 jusqu'à mi-hauteur de celles-ci.An alternative embodiment of the bracket 121 is shown on the Figure 9 . The oblong holes 161 are each open at the top in the mounting position according to an opening 161a opening horizontally in the free edge of the angle 121a. Thus are formed so-called buttonholes that facilitate the mounting of the plate 103. For this purpose, it comes to set up rivets or studs to crimp 160 in the return 121 to the different heights desired, these rivets or studs 160 being advantageously chosen so that their heads are embedded in the sheet metal of the return 121, their rods projecting inwards. At the time of assembly, the angle 121a is fixed with its buttonholes in the position of the Figure 9 and the outer plate 103 is brought back to the core 121 by horizontally inserting the rods of the rivets or studs 160 into the corresponding apertures 161a of the buttonholes, then the plate 103 is lowered, the rivets or studs 160 descending the oblong parts 161 up to half height of these.

Dans le cas où l'on prévoit une plaque rapportée en matière plastique dure isolante, on peut former les boutonnières directement dans le chant vertical de cette plaque, sans avoir recours à une cornière.In the case where an insulating hard plastic insert is provided, the buttonholes can be formed directly in the vertical edge of this plate, without having to use an angle iron.

Des essais conduits par le Demandeur ont monté l'absence de gondolage de panneaux soumis à des températures élevées par comparaison à des mêmes panneaux ne comportant pas les modifications de surface de l'âme du panneau sandwich. Les plots formés en surface de l'âme ont ainsi permis une dilatation sous des effets bilame individuels, réduits, n'affectant pas l'ensemble du panneau.Tests conducted by the Applicant have mounted the absence of curling panels subjected to high temperatures compared to the same panels not having the surface modifications of the core of the sandwich panel. The pads formed on the surface of the core have thus allowed expansion under reduced individual bimetallic effects, not affecting the entire panel.

Il est du reste bien entendu que les modes de réalisation qui viennent d'être décrits ont été donnés à titre indicatif et non limitatif et que des modifications peuvent être apportées sans que l'on s'écarte pour autant du cadre de la présente invention.It is, of course, understood that the embodiments which have just been described have been given as an indication and not a limitation and that modifications can be made without departing from the scope of the present invention.
