Description

La présente invention a pour objet une paroi intérieure de bardage ou de couverture métallique réalisée à partir de profilés métalliques enserrant une couche en matériau isolant pour la réalisation de bâtiments du type industriels, commerciaux ou publics.The present invention relates to an interior wall of cladding or metal cover made from metal profiles enclosing a layer of insulating material for the production of buildings of the industrial, commercial or public type.

La présente invention a également pour objet un profil de renfort d'une telle paroi intérieure de bardage ou de couverture métallique.The present invention also relates to a reinforcing profile of such an interior wall of cladding or metal cover.

Généralement, les bardages ou les couvertures métalliques comportent une paroi intérieure formée d'un assemblage de profilés fixés sur les éléments d'une charpente constituant l'ossature du bâtiment, une couche de matériau isolant et une paroi extérieure.Generally, metal cladding or roofing comprises an interior wall formed by an assembly of profiles fixed to the elements of a frame constituting the framework of the building, a layer of insulating material and an exterior wall.

Cette paroi extérieure est également formée d'un assemblage de profilés fixés directement sur les profilés formant la paroi intérieure dans le cas des bardages dits à trame croisée ou fixés aux profilés formant la paroi intérieure par l'intermédiaire d'éléments secondaires intermédiaires dans le cas des bardages dits à trame parallèle.This outer wall is also formed by an assembly of profiles fixed directly to the profiles forming the inner wall in the case of so-called cross-frame cladding or fixed to the profiles forming the inner wall by means of intermediate secondary elements in the case so-called parallel weft cladding.

Habituellement, les profilés utilisés pour former la paroi intérieure sont des profilés métalliques, nervurés à section générale en forme de U, comportant une âme encadrée par des ailes bordées par des rives rabattues vers l'extérieur et terminées par des rebords.Usually, the profiles used to form the interior wall are metal profiles, ribbed in general U-shaped section, having a core framed by wings bordered by edges folded outwards and terminated by flanges.

Ces profilés sont juxtaposés et assemblés les uns avec les autres par emboîtement de leurs ailes respectives pour former la paroi intérieure du bardage métallique.These profiles are juxtaposed and assembled with each other by fitting their respective wings to form the inner wall of the metal cladding.

La paroi intérieure du bardage métallique a pour fonction de fermer le bâtiment et de transmettre à la charpente dudit bâtiment les efforts dus au vent.The inner wall of the metal cladding has the function of closing the building and transmitting to the frame of said building the forces due to the wind.

Dans le cas des couvertures, la paroi intérieure a également pour fonction de transmettre les efforts dus à la neige et dus à la circulation des personnes par exemple pour l'entretien.In the case of blankets, the wall interior also has the function of transmitting the forces due to snow and due to the movement of people for example for maintenance.

Dans le cas des bardages ou couvertures dits à trame croisée, les efforts subis par la paroi extérieure sont transmis à la paroi intérieure directement et, dans le cas des bardages ou couvertures à trame parallèle, les efforts sont transmis à la paroi intérieure par les éléments secondaires intermédiaires.In the case of cladding or roofing known as cross-weaving, the forces undergone by the external wall are transmitted to the internal wall directly and, in the case of cladding or roofing with parallel grid, the forces are transmitted to the internal wall by the elements secondary secondary.

Pour des raisons évidentes d'esthétique, les profilés utilisés pour réaliser la paroi intérieure ont une âme plane ou faiblement nervurée pour donner à ladite paroi intérieure un aspect plan.For obvious aesthetic reasons, the profiles used to make the interior wall have a flat or slightly ribbed core to give said interior wall a planar appearance.

Cette configuration plane a des conséquences dans le domaine de la résistance des matériaux.This planar configuration has consequences in the field of the resistance of materials.

En effet, les parties planes sont larges et ont une faible capacité à résister à des efforts de compression situés dans leur plan ce qui reporte les efforts sur les nervures.In fact, the flat parts are wide and have a low capacity to withstand compression forces located in their plane, which transfers the forces to the ribs.

De plus, les nervures sont hautes et présentent une faible épaisseur si bien qu'elles sont sensibles au flambement.In addition, the ribs are high and have a small thickness so that they are sensitive to buckling.

Ainsi, dans le cas d'une paroi intérieure réalisée par emboîtement de profilés nervurés, présentant une section générale en forme de U, et fixée sur trois éléments de la charpente du bâtiment, un élément central et deux éléments latéraux servant également à fixer la rangée adjacente de profilés, cette paroi intérieure présente un voilement lorsque les profilés sont soumis aux efforts dus au vent.Thus, in the case of an interior wall produced by interlocking ribbed profiles, having a general U-shaped section, and fixed on three elements of the building frame, a central element and two lateral elements also serving to fix the row adjacent profiles, this inner wall has a buckling when the profiles are subjected to the forces due to the wind.

Par ailleurs, au niveau de l'appui central, la paroi intérieure est soumise à une flexion et à une compression ce qui se traduit, dès que les efforts deviennent importants par une modification de la forme des profilés par l'écrasement et la diminution de la hauteur des nervures.Furthermore, at the level of the central support, the inner wall is subjected to a bending and a compression which results, as soon as the forces become significant by a modification of the shape of the profiles by the crushing and the reduction of the rib height.

Cet écrasement des nervures entraine une diminution des performances mécaniques de la paroi intérieure provoquant ainsi une ruine rapide de cette paroi intérieure et une flèche de déformation importante.This crushing of the ribs causes a reduction in the mechanical performance of the inner wall, thus causing rapid ruin of this inner wall and a significant deflection deflection.

Or, les règlements en matière de bardage métallique de bâtiment imposent une flèche maximale et des coefficients de sécurité à la ruine.However, the regulations for metallic cladding of buildings impose a maximum deflection and safety factors for failure.

L'invention a pour but de proposer une paroi intérieure de bardage ou de couverture métallique de bâtiment permettant de retarder l'écrasement des nervures au niveau des appuis et principalement au niveau de l'appui central dans le cas des structures à double portée.The object of the invention is to propose an interior wall of cladding or metal covering of a building making it possible to delay the crushing of the ribs at the level of the supports and mainly at the level of the central support in the case of double-span structures.

L'invention a donc pour objet une paroi intérieure de bardage ou de couverture métallique de bâtiment comportant une charpente, ladite paroi étant formée par des profilés nervurés et juxtaposés à section générale en forme de U comprenant chacun une âme munie sur deux de ses bords longitudinaux parallèles d'une aile bordée par une rive rabattue et formant avec l'aile et la rive du profilé adjacent un assemblage par emboîtement, lesdits profilés étant maintenus sur les éléments de la charpente par des moyens de fixation, caractérisée en ce qu'elle comporte au niveau d'au moins un assemblage par emboîtement au moins un profil de renfort formé, d'une part, de deux semelles parallèles, une première semelle étant appliquée contre l'âme de l'un des profilés nervurés et une seconde semelle étant appliquée contre la rive rabattue dudit profilé et, d'autre part, d'une âme réunissant lesdites semelles.The invention therefore relates to an interior wall of cladding or metal roofing of a building comprising a frame, said wall being formed by ribbed and juxtaposed sections of general U-shaped section each comprising a core provided on two of its longitudinal edges. parallels of a wing bordered by a folded edge and forming with the wing and the edge of the adjacent profile an interlocking assembly, said profiles being held on the elements of the frame by fixing means, characterized in that it comprises at at least one interlocking assembly at least one reinforcing profile formed, on the one hand, of two parallel flanges, a first flange being applied against the core of one of the ribbed profiles and a second flange being applied against the folded edge of said profile and, on the other hand, of a core joining said soles.

Chaque profilé 10 a une section générale en forme de U comportant une âme 11 munie, d'une part, au niveau de son bord longitudinal supérieur 11a, d'une aile 12a bordée par une rive 13a rabattue vers l'intérieur du profilé 10 et terminée par un rebord 14a et, d'autre part, au niveau de son bord longitudinal inférieur 11b d'une aile 12b bordée par une rive 13b rabattue vers l'extérieur du profilé 10 et terminée par un rebord 14b.Each profile 10 has a general U-shaped section comprising a core 11 provided, on the one hand, at its upper longitudinal edge 11a, of a wing 12a bordered by an edge 13a folded inwardly of the profile 10 and terminated by a rim 14a and, on the other hand, at its lower longitudinal edge 11b of a wing 12b bordered by an edge 13b folded outwards from the profile 10 and terminated by a rim 14b.

Les ailes 12a et 12b et les rives 13a et 13b des profilés 10 adjacents sont emboîtées les unes dans les autres comme représentées sur les Figs. 1 à 3.The wings 12a and 12b and the edges 13a and 13b of the adjacent sections 10 are nested one inside the other as shown in FIGS. 1 to 3.

L'âme 11 des profilés 10 est sensiblement plane et est munie de nervures 15 en saillie vers l'intérieur du U et parallèles entre elles et aux bords longitudinaux 11a et 11b de ladite âme 11.The core 11 of the profiles 10 is substantially planar and is provided with ribs 15 projecting towards the inside of the U and parallel to each other and to the longitudinal edges 11a and 11b of said core 11.

Les profilés 10 sont fixés sur les éléments 4 de la charpente par des moyens de fixation 5 appropriés (Fig. 3).The sections 10 are fixed to the elements 4 of the frame by appropriate fixing means 5 (Fig. 3).

Dans le cas de bardages à trame croisée tels que représentés à la Fig. 1, la paroi extérieure 2 est formée de profilés disposés verticalement d'un autre type que ceux constituant la paroi intérieure 1 et fixés aux profilés 10 de ladite paroi intérieure 1 par des moyens de fixation non représentés, du type par exemple vis taraudeuses, vis écrou, clous, rivets...In the case of cross-grid cladding as shown in FIG. 1, the outer wall 2 is formed of profiles arranged vertically of another type than those constituting the inner wall 1 and fixed to the profiles 10 of said inner wall 1 by fixing means not shown, of the type for example tapping screws, screws nut, nails, rivets ...

Dans le cas de bardages à trame parallèle tels que représenté à la Fig. 2, la paroi extérieure 2 est formée de profilés d'un autre type que ceux constituant la paroi intérieure 1 et disposés également horizontalement. Les profilés de la paroi extérieure 2 sont fixés aux profilés 10 de la paroi intérieure 1 par l'intermédiaire d'éléments secondaires 6 parallèles aux éléments 4 de la charpente.In the case of cladding with a parallel grid as shown in FIG. 2, the outer wall 2 is formed of profiles of another type than those constituting the inner wall 1 and also arranged horizontally. The profiles of the outer wall 2 are fixed to the profiles 10 of the inner wall 1 by means of secondary elements 6 parallel to the elements 4 of the frame.

Comme représenté à la Fig. 3, la paroi intérieure 1 du bardage métallique comporte, au niveau de chaque assemblage par emboîtement des profilés 10, au moins un profil de renfort 20.As shown in Fig. 3, the internal wall 1 of the metal cladding comprises, at the level of each assembly by interlocking of the profiles 10, at least one reinforcing profile 20.

Chaque profil de renfort 20 comporte, d'une part, deux semelles parallèles, une première semelle 21 appliquée contre l'âme 11 de l'un des profilés 10 et une seconde semelle 22 appliquée contre la rive rabattue 13a dudit profilé 10 et, d'autre part, une âme 23 réunissant les deux semelles 21 et 22.Each reinforcement profile 20 comprises, on the one hand, two parallel flanges, a first sole 21 applied against the core 11 of one of the profiles 10 and a second sole 22 applied against the folded edge 13a of said profile 10 and, d on the other hand, a core 23 joining the two soles 21 and 22.

La première semelle 21 du profil de renfort 20 est fixée à l'âme 11 de l'un des profilés 10 par les moyens de fixation 5 dudit profilé 10 aux éléments 4 de la charpente.The first sole 21 of the reinforcing profile 20 is fixed to the core 11 of one of the profiles 10 by the means 5 for fixing said profile 10 to the elements 4 of the frame.

Préférentiellement, dans le cas où la paroi intérieure 1 est formée par l'assemblage de profilés 10 fixés sur trois éléments 4, un élément central et deux éléments latéraux, le profil de renfort 20 est fixé sur le profilé 10 au niveau de l'élément central.Preferably, in the case where the inner wall 1 is formed by the assembly of profiles 10 fixed on three elements 4, a central element and two lateral elements, the reinforcement profile 20 is fixed on the profile 10 at the level of the element central.

Mais, il est évident qu'un profil de renfort 20 peut être fixé dans les assemblages par emboîtement des profilés 10 au niveau de tous les éléments de la charpente sur lesquels sont fixés les profilés 10.However, it is obvious that a reinforcing profile 20 can be fixed in the assemblies by interlocking the profiles 10 at the level of all the elements of the frame on which the profiles 10 are fixed.

La longueur du profil de renfort 20 est supérieure à la largeur de l'élément 4 de la charpente sur lequel il est fixé.The length of the reinforcement profile 20 is greater than the width of the element 4 of the frame on which it is fixed.

Comme représenté sur la Fig. 3, le profil de renfort 20 a une section générale en forme de C, l'âme 23 dudit profil de renfort 20 étant en contact avec l'aile 12a du profilé 10 sur lequel est fixé ledit profil de renfort 20.As shown in Fig. 3, the reinforcement profile 20 has a general C-shaped section, the core 23 of said reinforcement profile 20 being in contact with the wing 12a of the profile 10 on which said reinforcement profile 20 is fixed.

Dans ce cas, la première semelle 21 est plus large que la seconde semelle 22, ladite seconde semelle 22 ayant une largeur sensiblement égale à la largeur de la rive 13a dudit profilé 10.In this case, the first sole 21 is wider than the second sole 22, said second sole 22 having a width substantially equal to the width of the edge 13a of said profile 10.

De préférence, la largeur de la première semelle 21 est égale au double de la largeur de la seconde semelle 22.Preferably, the width of the first sole 21 is equal to twice the width of the second sole 22.

Dans les variantes de réalisation représentées aux Figs. 4 et 5, le profil de renfort 20 a une section générale en forme de Z.In the variant embodiments shown in Figs. 4 and 5, the reinforcement profile 20 has a general Z-shaped section.

L'âme 23 du profil de renfort 20 peut être orthogonale aux semelles 21 et 22 (Fig. 5) ou non (Fig. 4).The core 23 of the reinforcement profile 20 can be orthogonal to the flanges 21 and 22 (Fig. 5) or not (Fig. 4).

Dans ces variantes, la largeur de la première semelle 21 est également supérieure à la largeur de la seconde semelle 22.In these variants, the width of the first sole 21 is also greater than the width of the second sole 22.

Selon une autre variante de réalisation représentée à la Fig. 6, le profil de renfort 20 a une section générale en forme de C, mais l'âme 23 dudit profil de renfort 20 n'est pas orthogonale aux semelles 21 et 22 si bien que ladite âme 23 n'est pas en contact avec l'aile 12a du profilé 10 sur lequel est fixé ledit profil de renfort 20.According to another alternative embodiment shown in FIG. 6, the reinforcement profile 20 has a general C-shaped section, but the core 23 of said reinforcement profile 20 is not orthogonal to the flanges 21 and 22 so that said core 23 is not in contact with the wing 12a of the section 10 on which said reinforcing profile 20 is fixed.

La Fig. 7 représente un autre mode de réalisation de paroi intérieure 1 dans laquelle chaque rive 13a et 13b des profilés 10 sont en saillie vers l'extérieur du U par rapport aux bords 11a et 11b de l'âme 11 dudit profilé 10 et dans laquelle la partie adjacente des ailes 12a et 12b avec les rives 13a et 13b sont en saillie vers l'intérieur du U par rapport aux bords longitudinaux 11a et 11b de l'âme 11 desdits profilés 10.Fig. 7 shows another embodiment of the inner wall 1 in which each bank 13a and 13b of the profiles 10 project outwards from the U relative to the edges 11a and 11b of the core 11 of the said profile 10 and in which the part adjacent wings 12a and 12b with the edges 13a and 13b protrude towards the inside of the U with respect to the longitudinal edges 11a and 11b of the core 11 of said sections 10.

Ainsi, lors de l'assemblage de deux profilés 10 juxtaposés, les ailes 12a et 12b, adjacentes desdits profilés 10 forment un caisson 16 par emboîtement réciproque des rives 13a et 13b et des rebords 14a et 14b de ces profilés 10.Thus, during the assembly of two juxtaposed sections 10, the flanges 12a and 12b, adjacent to said sections 10 form a box 16 by reciprocal fitting of the edges 13a and 13b and the flanges 14a and 14b of these sections 10.

Dans ce cas, le profil de renfort 20 a la forme générale d'un Z dans lequel la seconde semelle 22 est prisonnière entre les rives 13a et 13b de chaque profilé 10 adjacent et la première semelle 21 est appliquée contre l'âme 11 de l'un des profilés 10.In this case, the reinforcing profile 20 has the general shape of a Z in which the second sole 22 is trapped between the edges 13a and 13b of each adjacent profile 10 and the first sole 21 is applied against the core 11 of the 'one of the profiles 10.

Cette première semelle 21 est de préférence fixée à ce profilé 10 par l'intermédiaire des moyens de fixation dudit profilé aux éléments de la charpente.This first sole 21 is preferably fixed to this profile 10 by means of the fixing of said profile to the elements of the frame.

L'âme 23 est orthogonale aux semelles 21 et 22.The core 23 is orthogonal to the soles 21 and 22.

Le bord libre longitudinal de chaque semelle 21 et 22 du profil de renfort 20 peut comporter un rebord rabattu.The longitudinal free edge of each sole 21 and 22 of the reinforcement profile 20 may have a folded rim.

Les essais réalisés avec des parois intérieures selon l'invention ont montré que de telles parois peuvent reprendre 20% de charge en plus, tout en satisfaisant au règlement quant à la flèche et à la ruine.The tests carried out with interior walls according to the invention have shown that such walls can take up 20% more load, while satisfying the regulations regarding deflection and failure.

Ce résultat est d'autant plus significatif qu'il est obtenu par l'adjonction aux parois intérieures utilisées jusqu'à présent, de profils de renfort ne représentant qu'une augmentation de poids de lesdites parois intérieures de l'ordre de 2%.This result is all the more significant since it is obtained by adding to the interior walls used until now, reinforcement profiles representing only an increase in weight of said interior walls of the order of 2%.

Outre l'augmentation des performances mécaniques des parois intérieures de bardage métallique, lesdites parois intérieures présentent l'avantage de ne pas se différencier des parois intérieures utilisées jusqu'à présent car les profils de renfort sont invisibles lorsqu'ils sont installés.In addition to increasing the mechanical performance of the interior walls of metal cladding, said interior walls have the advantage of not being different from the interior walls used until now because the reinforcement profiles are invisible when installed.

Enfin, le profil de renfort peut se combiner avec la fonction "éclisse". Dans ce cas, il sert d'élément de renfort pour relier les deux extrémités de deux parois successives et permet de transmettre tout ou partie de contraintes d'une paroi à l'autre.Finally, the reinforcement profile can be combined with the "splint" function. In this case, it serves as a reinforcing element for connecting the two ends of two successive walls and makes it possible to transmit all or part of the stresses from one wall to the other.

Un autre avantage du profil de renfort selon l'invention réside dans sa simplicité de mise en oeuvre et son faible coût, car la pose s'effectue sans aucune fixation supplémentaire.Another advantage of the reinforcement profile according to the invention lies in its simplicity of implementation and its low cost, since the installation is carried out without any additional fixing.
