Description

Objet de l'inventionObject of the invention

La présente invention se rapporte au domaine de la construction, en particulier à celui de la réalisation de dispositifs et accessoires destinés à assurer l'isolation en cas de ruptures thermiques principalement en cas d'interruption dans l'isolation des bâtiments en général.The present invention relates to the field of construction, in particular to the realization of devices and accessories intended to provide insulation in the event of thermal breaks mainly in case of interruption in the insulation of buildings in general.

Etat de la techniqueState of the art

Les problèmes liés aux ponts thermiques provoqués principalement par l'interruption de l'isolant au droit des jonctions de structures extérieures (par exemple éléments en porte-à-faux) sont bien connus dans le domaine de la construction. Les dispositifs destinés à réduire ces déperditions calorifiques consistent en général à assurer la continuité de l'isolation thermique par interposition d'un isolant traversé seulement par des éléments ponctuels de structure métallique qui assurent la transmission des efforts (effort tranchant et moment fléchissant).The problems related to thermal bridges caused mainly by the interruption of the insulation at the junctions of external structures (for example cantilevered elements) are well known in the field of construction. The devices intended to reduce these heat losses generally consist in ensuring the continuity of the thermal insulation by interposition of an insulation traversed only by point elements of metal structure which ensure the transmission of the forces (shearing force and bending moment).

Généralement l'élément d'isolation comprend une plaque d'isolant rigide ou quasi-rigide traversée par des barres d'armature, de préférence protégées contre la corrosion, au moins au droit du passage dans l'élément isolant. Les barres sont ancrées dans les éléments de structure de part et d'autre de l'élément isolant. L'élément est posé de telle sorte que la plaque d'isolant soit dans le prolongement de l'isolation courante du bâtiment, qu'elle soit extérieure ou intérieure à la structure porteuse.Generally the insulation element comprises a rigid or quasi-rigid insulating plate traversed by reinforcing bars, preferably protected against corrosion, at least to the right of the passage in the insulating element. The bars are anchored in the structural elements on either side of the insulating element. The element is laid in such a way that the insulation board either in the extension of the current insulation of the building, whether external or internal to the supporting structure.

Habituellement, cette plaque relativement rigide est constituée d'un matériau qui présente des caractéristiques assurant non seulement les performances d'isolation thermique, anti-feu et acoustique requises et correspondant au cahier des charges mais sert également de support aux barres d'armature.Usually, this relatively rigid plate is made of a material that has characteristics that not only provide the required thermal, fireproof and acoustic insulation performance and correspond to the specifications but also serves as support for the reinforcing bars.

Par barres d'armature, on entend des barres de renforcement destinées à être coulées dans le béton adjacent à l'élément isolant. De ce fait, on appelle également ces barres des barres à béton. Elles sont habituellement réalisées en acier, si possible en acier inoxydable, mais il est bien entendu possible d'envisager d'utiliser de nouveaux matériaux particulièrement résistants, tels que des barres en matériau polymérique en fibre ou en résine.Reinforcing bars are reinforcement bars intended to be poured into the concrete adjacent to the insulating element. As a result, these bars are also called concrete bars. They are usually made of steel, if possible stainless steel, but it is of course possible to consider using new particularly resistant materials, such as rods of polymeric material fiber or resin.

Il est admis de proposer des barres rectilignes s'étendant transversalement de part et d'autre de l'épaisseur de la plaque d'isolant. De plus, il est habituel de disposer au moins une barre en diagonale ou oblique traversant la hauteur de la plaque d'isolant. Ces barres sont généralement continues et traversent de part en part le matériau isolant mais utilisent sa rigidité pour un positionnement adéquat. En outre, dans le cas de barres disposées en diagonale sur la hauteur de la plaque d'isolant, il convient de préférence de la disposer de telle sorte que les rayons de courbure correspondant aux coudes ne soient pas noyés dans le matériau isolant, ce qui bien entendu impose des contraintes supplémentaires au choix de l'épaisseur de la plaque isolante.It is permissible to propose rectilinear bars extending transversely on both sides of the thickness of the insulating plate. In addition, it is usual to have at least one bar diagonally or oblique through the height of the insulating plate. These bars are generally continuous and pass right through the insulating material but use its rigidity for proper positioning. Furthermore, in the case of bars arranged diagonally over the height of the insulating plate, it is preferable to arrange it so that the radii of curvature corresponding to the elbows are not embedded in the insulating material, which of course imposes additional constraints on the choice of the thickness of the insulating plate.

Dans l'épaisseur de l'élément isolant, en l'absence de béton, les barres sont disposées et sont dimensionnées pour reprendre le moment fléchissant par un couple traction-compression dans les barres horizontales supérieures et inférieures qui équipent le dispositif. Une difficulté consiste à maintenir la juste distance entre ces barres pour ne pas modifier les efforts dans les barres par modification du bras de levier. Ecarter les barres conduit à réduire l'enrobage, les rapprocher augmente sensiblement les efforts dans les barres.In the thickness of the insulating element, in the absence of concrete, the bars are arranged and are dimensioned to take the bending moment by a pull-compression torque in the upper and lower horizontal bars that equip the device. A difficulty is to maintain the right distance between these bars not to change the forces in the bars by changing the lever arm. Spreading the bars leads to reduce the coating, bringing them together increases the efforts in the bars.

Dans certains cas, ce matériau isolant n'étant pas suffisamment résistant, le positionnement des barres nécessite de rajouter des barres de montage ou d'autres dispositifs compliqués qui peuvent aussi gêner la mise en oeuvre lorsque les éléments sont destinés à s'intégrer dans un ferraillage plus dense (poutres par exemple).In some cases, this insulating material is not strong enough, the positioning of the bars requires adding mounting bars or other complicated devices that can also hinder the implementation when the elements are intended to integrate into a denser reinforcement (beams for example).

Enfin, le matériau isolant constituant la plaque est relativement fragile, il peut s'effriter en particulier sur son pourtour comme aux arêtes par exemple, ce qui se produira d'autant plus souvent que le dispositif est en réalité préfabriqué en atelier et doit être transporté sur chantier où il peut subir des dommages.Finally, the insulating material constituting the plate is relatively fragile, it can crumble especially around its periphery as the edges, for example, which will occur more often than the device is actually prefabricated in the workshop and must be transported on site where he may suffer damage.

Un autre problème provient du fait que les barres d'armature qui sont généralement réalisées en acier inoxydable présentent un coût élevé pour la réalisation de ce dispositif.Another problem stems from the fact that rebars, which are generally made of stainless steel, have a high cost for producing this device.

Une solution possible est de ne prévoir l'acier inoxydable que sur une longueur réduite de chaque côté de l'élément isolant et d'y souder un complément de barre en acier traditionnel au carbone. Ce dispositif avantageux au niveau du coût de production est toutefois tributaire de la qualité de la soudure, précisément parce qu'elle est disposée dans la zone où l'effort est maximum. Ce dispositif présente donc un risque de corrosion lié à la formation d'oxydes lors de la soudure. Les conséquences d'une soudure défectueuse ou de la corrosion peuvent être dramatiques dans le cas d'accrochage d'un balcon par exemple, puisque la rupture d'une barre va provoquer une surcharge sur la barre voisine qui risque de ne pas résister.One possible solution is to provide the stainless steel only for a reduced length on each side of the insulating element and to weld a complement of traditional carbon steel bar. This advantageous device in terms of production cost is however dependent on the quality of the weld, precisely because it is located in the zone where the effort is maximum. This device therefore has a risk of corrosion related to the formation of oxides during welding. The results defective welding or corrosion can be dramatic in the case of hanging a balcony for example, since breaking a bar will cause an overload on the next bar that may not resist.

Buts de l'inventionGoals of the invention

La présente invention vise avantageusement à trouver une solution au problème de l'état de la technique et en particulier à surmonter les différents inconvénients décrits ci-dessus.The present invention is advantageously aimed at finding a solution to the problem of the state of the art and in particular to overcome the various disadvantages described above.

La présente invention a également pour but de réaliser un élément qui limite la longueur des barres d'armature protégées contre la corrosion par exemple pour garder l'avantage du coût réduit, en réalisant un assemblage mécanique avec les barres courantes pour supprimer le risque lié à la soudure tout en permettant de réduire le nombre de pièces à assembler et donc le coût du montage.Another object of the present invention is to provide an element which limits the length of the corrosion-protected reinforcing bars, for example to keep the advantage of the reduced cost, by mechanically joining the current bars to eliminate the risk associated with welding while reducing the number of parts to be assembled and therefore the cost of assembly.

A titre accessoire, la présente invention vise à proposer une solution qui n'utilise pas la résistance mécanique de la plaque d'isolant comme support pour le placement adéquat des barres d'armature.As an accessory, the present invention aims to provide a solution that does not use the strength of the insulating plate as a support for the proper placement of rebar.

De ce fait, la présente invention vise également à proposer une solution qui permet de choisir l'isolant adéquat uniquement en fonction de ses caractéristiques thermiques, anti-feu et/ou acoustique sans devoir vérifier les caractéristiques de stabilité de ladite plaque.Therefore, the present invention also aims to provide a solution that allows to choose the appropriate insulation only according to its thermal, fire and / or acoustic characteristics without having to check the stability characteristics of said plate.

Principaux éléments caractéristiques de l'inventionMain characteristic elements of the invention

La présente invention se rapporte à un dispositif destiné à effectuer la jonction au sein d'un élément d'isolation entre deux barres ou parties de barres d'armature, caractérisé en ce qu'il se présente sous la forme d'un manchon ou pièce intercalaire permettant d'assembler les deux ou les deux parties de barres d'armature par un assemblage mécanique.The present invention relates to a device for effecting the junction within an insulation element between two bars or parts of bars reinforcement, characterized in that it is in the form of a sleeve or insert to assemble the two or both parts of reinforcing bars by a mechanical assembly.

De préférence, la longueur du manchon est supérieure à l'épaisseur de l'élément d'isolation.Preferably, the length of the sleeve is greater than the thickness of the insulation member.

De préférence, ledit manchon présente en sa partie centrale une réduction de section par rapport à la section de ses deux extrémités.Preferably, said sleeve has in its central part a section reduction with respect to the section of its two ends.

Par caisson ou cage, on entend un élément rigide indéformable qui définit l'espace dans lequel le matériau isolant est enfermé. Cela signifie également que selon au moins une vue en coupe, le profil du caisson ou de la cage peut/doit présenter un pourtour complètement fermé.Box or cage means a rigid non-deformable element which defines the space in which the insulating material is enclosed. This also means that in at least one sectional view, the profile of the box or the cage can / must have a completely closed periphery.

La présente invention se rapporte donc également à un dispositif destiné à assurer l'isolation en cas de rupture thermique se présentant sous la forme d'un élément de construction, comprenant un matériau isolant à disposer selon une direction essentiellement longitudinale entre deux parties de bâtiment, et des barres d'armature qui traversent le matériau isolant, caractérisé en ce que le dispositif comprend un profil se présentant sous la forme d'un caisson ou d'une cage ouvert ou fermé et qui définit un espace intérieur dans lequel est disposé ledit matériau isolant, les barres d'armature étant reliées entre elles au sein même du matériau isolant par l'intermédiaire d'un dispositif tel que décrit ci-dessus.The present invention therefore also relates to a device for insulating in case of thermal break in the form of a construction element, comprising an insulating material to be arranged in a substantially longitudinal direction between two building parts, and reinforcing bars which pass through the insulating material, characterized in that the device comprises a profile in the form of a box or an open or closed cage and which defines an interior space in which said material is disposed insulation, the reinforcing bars being interconnected within the same insulating material via a device as described above.

Les figures 6 et 7 décrivent des formes d'exécution particulière de l'invention pour l'utilisation d'un caisson ou d'une cage constituant l'élément d'isolation.The figures 6 and 7 describe particular embodiments of the invention for the use of a box or a cage constituting the insulation element.

Description détaillée de plusieurs formes d'exécution préférée de l'inventionDetailed description of several preferred embodiments of the invention

Les figures 1a et 1b décrivent de manière schématique une vue en coupe d'un dispositif d'isolation qui met en oeuvre le principe selon la présente invention.The Figures 1a and 1b schematically describe a sectional view of an isolation device which implements the principle according to the present invention.

Selon la figure 1a, un élément d'isolation 7 rigide ou semi-rigide est équipé de barres d'armature 20, 30 ou autres pièces permettant d'assurer la stabilité des ouvrages.According to figure 1a , a rigid or semi-rigid insulation element 7 is equipped with reinforcing bars 20, 30 or other parts to ensure the stability of the structures.

Selon 1a figure 1b, un caisson ou une cage rigide essentiellement indéformable 10 est présent et est équipé de barres d'armature 20, 30 ou autres pièces permettant d'assurer la stabilité desdits ouvrages, ledit caisson ou ladite cage pouvant être rempli d'un matériau isolant 107 de quelque nature que ce soit selon les exigences de chaque application particulière.According to 1a figure 1b a box or a rigid cage essentially indeformable 10 is present and is equipped with reinforcing bars 20, 30 or other parts to ensure the stability of said structures, said box or said cage being filled with an insulating material 107 of whatever it may be according to the requirements of each particular application.

Selon une caractéristique essentielle de la présente invention, les barres d'armature extérieures au matériau isolant sont reliées entre elles par un manchon 10 qui traverse l'épaisseur de l'isolant rigide, semi-rigide ou non rigide sur toute cette épaisseur. De manière particulièrement avantageuse, l'assemblage des barres d'armature avec le manchon s'effectue par un assemblage mécanique.According to an essential characteristic of the present invention, the reinforcing bars external to the insulating material are interconnected by a sleeve 10 which passes through the thickness of the rigid, semi-rigid or non-rigid insulation throughout this thickness. In a particularly advantageous manner, the assembly of the reinforcing bars with the sleeve is carried out by a mechanical assembly.

Par assemblage mécanique, on entend un assemblage qui ne nécessite pas l'utilisation d'un adhésif ou d'un traitement spécifique, seule la forme des extrémités est adaptée pour permettre la solidarisation. Un assemblage mécanique, doit être opposé à un assemblage chimique ou thermique qui nécessite la présence d'un agent chimique tel que de la colle ou un adhésif ou le traitement thermique tel qu'une soudure. L'assemblage mécanique offre l'avantage de pouvoir permettre si nécessaire la désolidarisation permettant de faciliter le transport et la mise en place mais surtout réduit les risques de corrosion.Mechanical assembly means an assembly that does not require the use of an adhesive or a specific treatment, only the shape of the ends is adapted to allow the joining. A mechanical assembly must be opposed to a chemical or thermal assembly which requires the presence of a chemical agent such as glue or adhesive or heat treatment such as welding. The mechanical assembly offers the advantage of being able to allow, if necessary, the separation to facilitate transport and installation but especially reduces the risk of corrosion.

Selon une première forme d'exécution, cet assemblage mécanique peut s'effectuer par filetage. Une autre forme d'exécution permet d'envisager un clipsage de différents éléments et en particulier d'une extrémité d'un manchon avec une extrémité d'une barre d'armature.According to a first embodiment, this mechanical assembly can be made by threading. Another embodiment makes it possible to envisage clipping of different elements and in particular of one end of a sleeve with one end of a reinforcing bar.

Selon une autre forme d'exécution, on peut envisager un emboitement d'éléments mâles avec des éléments femelles chacun présent respectivement sur une extrémité du manchon et une extrémité de barre d'armature ou inversement.According to another embodiment, it is possible to envisage a fitting of male elements with female elements each respectively present on one end of the sleeve and one end of rebar or vice versa.

Ce manchon 10 se présente donc de manière avantageuse sous la forme d'une pièce intermédiaire ou intercalaire qui sert de jonction entre deux barres d'armature successives 20, 30 réalisées de manière classique. La nature du manchon est telle qu'il est protégé contre la corrosion et il sera avantageusement réalisé en acier inoxydable ou en un matériau polymérique, par exemple en fibre ou en résine. Selon une autre alternative, il sera enrobé d'un revêtement anticorrosion.This sleeve 10 is therefore advantageously in the form of an intermediate piece or interlayer which serves as a junction between two successive reinforcing bars 20, 30 made in a conventional manner. The nature of the sleeve is such that it is protected against corrosion and it will advantageously be made of stainless steel or of a polymeric material, for example fiber or resin. According to another alternative, it will be coated with an anticorrosive coating.

Une autre caractéristique intéressante de la présente invention est que le manchon présente dans sa partie centrale une section réduite par rapport à ses extrémités. Avantageusement, cette section réduite permet également de réduire les flux thermiques et donc permettre une meilleure isolation en réduisant les déperditions thermiques.Another interesting feature of the present invention is that the sleeve has in its central portion a reduced section relative to its ends. Advantageously, this reduced section also makes it possible to reduce heat flows and thus allow better insulation by reducing heat losses.

Une autre caractéristique intéressante de la présente invention réside dans le fait que ledit manchon présente sur sa surface externe un relief. Ce relief peut avoir toute forme et est prévu essentiellement pour arrêter un cheminement éventuel d'eau qui favoriserait donc une certaine corrosion.Another interesting feature of the present invention lies in the fact that said sleeve has on its outer surface a relief. This relief may have any shape and is intended essentially to stop a possible path of water that would promote some corrosion.

Selon une forme d'exécution préférée, ce relief est réalisé par la présence de rainures sur la surface extérieure dudit manchon.According to a preferred embodiment, this relief is achieved by the presence of grooves on the outer surface of said sleeve.

La figure 2 montre un exemple de manchon 10 selon une forme préférentielle de l'invention. Les extrémités 11, 12 sont travaillées pour y fixer mécaniquement des barres à béton courantes 20, 30. A titre d'exemple, un filetage, un clipsage ou un emboitement d'éléments complémentaires peut être envisagé. La zone centrale 14 présente avantageusement une réduction de section pour réduire les flux thermiques. De manière avantageuse un certain relief 15 peut être prévu pour arrêter un éventuel cheminement d'eau.The figure 2 shows an example of sleeve 10 according to a preferred form of the invention. The ends 11, 12 are worked to mechanically fasten concrete concrete bars 20, 30. For example, threading, clipping or interlocking complementary elements may be considered. The central zone 14 advantageously has a section reduction to reduce the heat flows. Advantageously, a certain relief 15 may be provided to stop a possible flow of water.

Par réduction de section, on entend tout simplement que la section est plus faible au centre du manchon qu'aux extrémités. Selon une première forme d'exécution classique, il suffit que le diamètre du manchon soit sensiblement de l'ordre du diamètre des barres adjacentes tandis que les extrémités présentent bien entendu un diamètre plus important permettant la solidarisation aux dites barres.Reduction of section simply means that the section is weaker in the center of the sleeve than at the ends. According to a first conventional embodiment, it is sufficient that the diameter of the sleeve is substantially of the order of the diameter of the adjacent bars while the ends of course have a larger diameter for securing to said bars.

La figure 3 montre de façon explicite un exemple de réalisation utilisant un manchon selon l'invention. Un élément isolant 7 ou 107, de préférence rigide ou semi-rigide ou encore éventuellement enfermé dans une cage indéformable 10, est traversé par un manchon 10. Ce manchon est de préférence réalisé en acier et est protégé contre la corrosion. Il présente une réduction de section 14 dans la traversée du matériau isolant 100 ou 107 pour réduire les déperditions thermiques. Des barres 20, 30 viennent se fixer mécaniquement aux extrémités du manchon. Le manchon peut en outre être avantageusement muni d'un relief 15, par exemple sous forme de rainures, destiné à empêcher la progression éventuelle de l'eau vers les barres adjacentes 20, 30 qui ne sont pas protégées contre la corrosion.The figure 3 shows explicitly an embodiment using a sleeve according to the invention. An insulating element 7 or 107, preferably rigid or semi-rigid or possibly enclosed in an indeformable cage 10, is traversed by a sleeve 10. This sleeve is preferably made of steel and is protected against corrosion. It presents a reduction of section 14 in the passage of the insulating material 100 or 107 to reduce heat loss. Bars 20, 30 are mechanically attached to the ends of the sleeve. The sleeve may also be advantageously provided with a relief 15, for example in the form of grooves, intended to prevent the possible progression of water to the adjacent bars 20, 30 which are not protected against corrosion.

Les figures 4 et 5 décrivent des formes d'exécution préférées d'un manchon 10 selon l'invention.The figures 4 and 5 describe preferred embodiments of a sleeve 10 according to the invention.

La figure 4 en particulier montre un exemple de manchon 10 selon l'invention. Dans cette forme d'exécution, la jonction mécanique est faite par un filetage 21, 31 sur chacune des barres 20, 30 qui assureront un contact avec les extrémités du manchon 10, extrémités qui présentent un filetage intérieur 17, 18 compatible avec celui 21, 31 réalisé sur les barres 20, 30. Le relief extérieur 15 est également représenté selon une forme préférentielle, mais pourrait avoir toute autre forme selon l'invention.The figure 4 in particular shows an example of sleeve 10 according to the invention. In this embodiment, the mechanical joint is made by a thread 21, 31 on each of the bars 20, 30 which will ensure contact with the ends of the sleeve 10, ends which have an internal thread 17, 18 compatible with that 21, 31 on the bars 20, 30. The outer relief 15 is also shown in a preferred form, but could have any other form according to the invention.

Les figures 5a et 5b montrent deux formes d'exécution selon l'invention lorsque les barres ne sont pas dans un même alignement, par exemple en oblique ou diagonal. Les manchons 19a et 19b peuvent avoir un profil quelconque, par exemple un pli ou un coude 13 pour relier les deux barres 20 et 30 en formant un angle.The Figures 5a and 5b show two embodiments of the invention when the bars are not in the same alignment, for example oblique or diagonal. The sleeves 19a and 19b may have any profile, for example a fold or a bend 13 for connecting the two bars 20 and 30 at an angle.

A titre accessoire, une caractéristique supplémentaire de l'invention réside dans la conception même du produit et en particulier de l'élément isolant en ce sens qu'il est réalisé sous la forme d'un caisson ou d'une cage essentiellement indéformable qui sert de support aux barres d'armature nécessaires à la stabilité et qui peut être rempli par un isolant de n'importe quel type pour répondre aux exigences en matière d'isolation thermique, acoustique et/ou de résistance au feu.As an accessory, an additional characteristic of the invention lies in the actual design of the product and in particular of the insulating element in that it is embodied in the form of a box or an essentially indeformable cage which serves of rebar support necessary for stability and which can be filled with any type of insulation for meet the requirements for thermal, acoustic and / or fire resistance.

Selon une forme d'exécution préférée, le caisson ou la cage présente dans au moins les deux directions perpendiculaires à la direction longitudinale des parois complètement fermées à l'exception des ouvertures destinées au passage des barres d'armature et/ou de leurs accessoires. Dans ce cas de figure, si ledit caisson ou ladite cage est fermé, il est en outre fermé sur ses deux dernières faces c'est-à-dire sur les six faces de manière à réaliser un espace clos sous la forme d'un parallélépipède, on pourrait même envisager l'utilisation de matériau isolant sous forme granuleuse, fibreuse ou même sous forme de gel ou de mousse qui pourrait être injectée ou même coulée dans l'espace clos.According to a preferred embodiment, the box or the cage has in at least both directions perpendicular to the longitudinal direction of the walls completely closed with the exception of openings for the passage of reinforcing bars and / or their accessories. In this case, if said box or said cage is closed, it is further closed on its last two faces, that is to say on the six faces so as to create a closed space in the form of a parallelepiped it could even be envisaged to use insulating material in granular, fibrous form or even in the form of a gel or foam that could be injected or even poured into the enclosed space.

Selon une autre forme d'exécution, le caisson ou la cage peut être partiellement ouvert ou présenter des parois partiellement ajourées.According to another embodiment, the box or the cage may be partially open or have partially perforated walls.

Selon la forme d'exécution décrite à la figure 6, le caisson ou cage 100 comprend deux profils continus, le premier est un profil supérieur 101 et le second est un profil inférieur 102 qui sont maintenus à distance par des écarteurs 103 de préférence ponctuels ou des parois latérales 104 pour former un caisson ou une cage relativement rigide et indéformable où sont fixées les barres d'armature (supérieure, inférieure ou en diagonale). L'espace libre 107 à l'intérieur du caisson ou de la cage peut être rempli d'un matériau isolant adéquat, même sans grande rigidité, qui réponde au mieux aux exigences de chaque situation particulière.According to the embodiment described in figure 6 , the box or cage 100 comprises two continuous profiles, the first is an upper profile 101 and the second is a lower profile 102 which are held at a distance by spacers 103 preferably point or side walls 104 to form a box or a cage relatively rigid and indeformable where the rebar is fixed (upper, lower or diagonally). The free space 107 inside the box or cage can be filled with a suitable insulating material, even without great rigidity, which best meets the requirements of each particular situation.

De nombreuses variantes sont possibles, en ce sens que les pièces supérieures et inférieures pourraient ne pas être continues et laisser des ouvertures, de même que les écarteurs latéraux pourraient être continus pour former des parois pleines de chaque côté de l'isolant. Toutes les combinaisons sont possibles et les exemples donnés aux figures 1 et 7 ne sont pas des limitations de l'invention. A l'extrême, le caisson pourrait être complètement fermé sur son pourtour ou largement ajouré sur toutes ses faces. Enfin, les barres 20, 30 représentées ne constituent pas une limitation, ce sont des éléments de stabilité et leur présence ou leur forme dépend des efforts à transmettre. De même le matériau constitutif du manchon et des barres n'est pas une limitation, les termes « barre d'armature en « acier » » sont utilisés pour une forme préférée de l'invention, mais tout autre matériau permettant de transmettre les efforts peut être envisagé.Many variants are possible, in that the upper and lower parts may not be continuous and leave openings, as the lateral spacers could be continuous for form solid walls on each side of the insulation. All combinations are possible and the examples given to figures 1 and 7 are not limitations of the invention. At the extreme, the box could be completely closed on its periphery or widely open on all sides. Finally, the bars 20, 30 shown do not constitute a limitation, they are stability elements and their presence or shape depends on the forces to be transmitted. Similarly, the material constituting the sleeve and bars is not a limitation, the terms "steel reinforcing bar" are used for a preferred form of the invention, but any other material for transmitting the forces can to be considered.

Un avantage important de la présente invention vise à proposer un profil de préférence métallique complètement équipé et qui peut être transporté sur chantier. On peut même envisager d'inclure le matériau isolant et les manchons déjà correctement disposés sur chantier et non en atelier comme c'est actuellement le cas. Ceci sera particulièrement avantageux dans le cas d'un élément isolant se présentant sous forme de matériau granuleux, fibreux ou même sous forme de gel ou mousse. De même si un tel dispositif est équipé d'un caisson ou cage de préférence métallique et des divers manchons directement fixés à ladite cage ou caisson, son transport en sera grandement facilité. Le montage s'effectuant ensuite sur chantier et visant à fixer les barres d'armature sur les extrémités des manchons et à introduire si cela n'a pas déjà été fait le matériau isolant au sein de la cage ou caisson. Ceci permet de proposer un dispositif qui est simple, peu coûteux à réaliser, qui est solide et qui permet de dissocier les fonctions de stabilité des exigences concernant les performances thermiques, acoustiques ou coupe-feu et de ce fait de proposer un dispositif qui au point de vue du dimensionnement est parfaitement apte à remplir ces performances. De manière particulièrement avantageuse, on choisira le matériau isolant de manière à s'assurer que l'épaisseur du caisson ou cage ne soit pas trop élevée et permette de préférence que les rayons de courbure des coudes des barres obliques ou disposées diagonalement selon ledit caisson ou cage soient situés en dehors de celui-ci.An important advantage of the present invention is to provide a fully equipped metal preferring profile that can be transported to the job site. It may even be considered to include the insulating material and sleeves already properly arranged on site and not in the workshop as is currently the case. This will be particularly advantageous in the case of an insulating element in the form of granular material, fibrous or even in the form of gel or foam. Similarly, if such a device is equipped with a box or preferably metal cage and various sleeves directly attached to said cage or box, its transport will be greatly facilitated. The assembly is then carried out on site and aimed at fixing the reinforcing bars on the ends of the sleeves and to introduce if it has not already been made the insulating material within the cage or box. This makes it possible to propose a device which is simple, inexpensive to produce, which is solid and which makes it possible to dissociate the stability functions from the requirements relating to thermal, acoustic or fireproof performance and thus to propose a device which from the dimensioning point of view is perfectly capable of fulfilling these performances. In a particularly advantageous manner, the insulating material will be chosen so as to ensure that the thickness of the box or cage is not too high and preferably allows the radii of curvature of the elbows of the oblique bars or diagonally arranged according to said box or cage are located outside of it.
