Abstract

The method involves forming a profiled insulating bar (1), and inserting a transversal end (3) of the bar into a profiled metal bar (2) by respectively embedding a back draft structure of a profile (4) and a rib (6) of the end into a housing (5) and a groove (7) of the metal bar. The bar (1) is crimped on the bar (2) to form a complete link between the bars such that an active part (11) partially forming the housing is deformed during crimping so as to make the bar (2) to exert a transversal reaction on the bar (1) via the groove and an additional support surface (12) of the metal bar. An independent claim is also included for a construction bar comprising a profiled insulating bar associated to a profiled metal bar.

Description

La présente invention se rapporte à un procédé de fabrication d'une barre de construction par sertissage, à partir d'au moins une barre isolante du type profilé et d'au moins une barre métallique du type profilé, liées entre elles par une liaison complète.The present invention relates to a method of manufacturing a crimping construction bar, from at least one insulating bar of the profiled type and at least one metal bar of the profiled type, linked together by a complete connection .

La présente invention se rapporte en outre à une barre de construction comportant une barre isolante et une barre métallique au moins, ainsi associées par une liaison complète.The present invention furthermore relates to a construction bar comprising at least one insulating bar and at least one metal bar, thus associated by a complete connection.

L'art antérieur enseigne une telle barre de construction, un exemple de cette dernière étant représenté sur la figure 1 ou la figure 2.The prior art teaches such a construction bar, an example of the latter being represented on the figure 1 or the figure 2 .

Sur ces figures, les éléments similaires assurant la même fonction portent les mêmes références, séparées du nombre 100.In these figures, the similar elements providing the same function carry the same references, separated from the number 100.

En considération de la figure 1, qui représente une barre de construction conventionnelle formant une traverse basse pour dormant, les barres métalliques 502 et 522 sont associées ensemble par l'intermédiaire de deux barres isolantes 501, dans l'exemple identiques. Une barre isolante comporte deux extrémités 503 et 523 respectivement serties dans les barres métalliques 502 et 522. Ces extrémités 503 et 523 sont, dans l'exemple, identiques, et constituées chacune par une tête triangulaire encastrée dont la base du triangle constitue la face d'extrémité de la barre isolante. Chaque logement d'encastrement 505, 525 dans chaque barre métallique 502, 522 pour chaque tête triangulaire d'une barre isolante 501 est de section transversale sensiblement triangulaire dont une paroi 511, 531, métallique, ou tête métallique de sertissage, accessible au moyen de sertissage, est apte à se déformer afin d'exercer une force de pression sur un côté de la tête triangulaire. Cette force de pression a comme effet de plaquer le côté opposé et la base de la tête triangulaire contre les faces d'appui correspondantes de la rainure triangulaire de la barre métallique constituant le logement de la tête triangulaire de la barre isolante.In consideration of figure 1 , which represents a conventional construction bar forming a low sleeper crossbar, the metal bars 502 and 522 are associated together through two insulating bars 501, in the same example. An insulating bar has two ends 503 and 523 respectively crimped into the metal bars 502 and 522. These ends 503 and 523 are, in the example, identical, and each constituted by a recessed triangular head whose base of the triangle constitutes the face d end of the insulating bar. Each recess housing 505, 525 in each metal bar 502, 522 for each triangular head of an insulating bar 501 is of substantially triangular cross-section, including a wall 511, 531, metal, or crimping metal head, accessible by means of crimping, is able to deform in order to exert a pressing force on one side of the triangular head. This pressure force has the effect of pressing the opposite side and the base of the triangular head against the corresponding bearing faces of the triangular groove of the metal bar constituting the housing of the triangular head of the insulating bar.

Sur la figure 2, qui représente une barre de construction conventionnelle formant un montant pour ouvrant, les éléments similaires à ceux de la figure 1 portent les mêmes références numériques additionnées du nombre 100.On the figure 2 , which represents a conventional construction bar forming an amount for opening, the elements similar to those of the figure 1 bear the same numerical references plus the number 100.

Une telle configuration présente des inconvénients.Such a configuration has disadvantages.

Un premier inconvénient réside dans le fait que l'assemblage d'une barre isolante avec un profilé métallique, en particulier par sertissage, entraîne des défauts géométriques susceptibles de modifier le dimensionnement des barres de construction obtenues, en sorte de ne pas respecter les tolérances de fabrication.A first disadvantage lies in the fact that the assembly of an insulating bar with a metal section, in particular by crimping, causes geometrical defects likely to modify the dimensioning of the bars of construction obtained, so as not to respect the tolerances of manufacturing.

En outre, un autre inconvénient réside dans le fait que la conception de la tête d'encastrement confère une résistance mécanique impliquant la nécessité d'avoir une tête d'encastrement par extrémité transversale de barre isolante et deux têtes d'encastrement par barre isolante, soit quatre têtes d'encastrement pour une barre de construction comportant deux barres isolantes, comme représenté sur les figures 1 et 2.In addition, another disadvantage lies in the fact that the design of the embedding head confers a mechanical strength implying the need to have a recessing head per transverse end of insulating bar and two insulating bar embedding heads, four mounting heads for a construction bar having two insulating bars, as shown in Figures 1 and 2 .

En outre, un autre inconvénient réside dans le fait de telles barres isolantes nécessitent, pour l'exemple de la figure 1 comme pour l'exemple de la figure 2, quatre sertissages et donc quatre têtes de sertissage métallique, et quatre accès libres à ces têtes ou parois métalliques, pour l'outil de sertissage. Ceci limite les capacités de conception des barres de construction, car il est impossible de placer une tête métallique de sertissage dans un endroit inaccessible à l'outil de sertissage. Par exemple, la figure 2 montre la nécessité d'étendre les parois de sertissage métallique 611 et 631 vers le plan médian de la barre de construction, uniquement afin de permettre l'action de l'outil de sertissage, autrement gêné par les rainures 637 et 638 de joint situées aux extrémités des profilés métalliques 622 et 602 respectivement.In addition, another disadvantage lies in the fact of such insulating bars require, for the example of the figure 1 as for the example of the figure 2 , four crimps and thus four metal crimping heads, and four free access to these metal heads or walls, for the crimping tool. This limits the design capabilities of the building bars because it is impossible to place a metal crimping head in a place inaccessible to the crimping tool. For example, the figure 2 shows the need to extend the metal crimping walls 611 and 631 towards the median plane of the construction bar, only to allow the action of the crimping tool, otherwise impeded by the grooves 637 and 638 of the seal located at ends of the metal profiles 622 and 602 respectively.

On connaît en outre les documents EP 0 235 493 et EP 0 943 775 qui permettent de pallier, en partie seulement, certains des inconvénients ci-dessus. Le document EP 0 235 493 se rapporte à une barre de construction assemblée par enlèvement de matière et sertissage, présentant un profilé composite thermiquement isolant pour fenêtres, portes, etc. comportant deux barrettes profilées isolantes serties suivant leurs deux extrémités transversales respectives dans deux profilés métalliques. Une extrémité transversale d'un profilé isolant, emboîtée dans un profilé métallique, présente une tête de sertissage longitudinale prolongée par une nervure elle-même longitudinale ; la tête de sertissage du profilé isolant est agencée pour être usinée par des dents formées dans le profilé métallique, lors de sa mise en place en force dans ce dernier ; la tête de sertissage du profilé isolant forme un angle droit avec le plan du profilé isolant lui-même reliant les deux profilés métalliques. Une telle technique d'assemblage demande un effort important pour l'opération de sertissage.In addition, the documents are known EP 0 235 493 and EP 0 943 775 which make it possible to overcome, in part only, some of the above disadvantages. The document EP 0 235 493 refers to a construction bar assembled by material removal and crimping, having a thermally insulating composite profile for windows, doors, etc. comprising two insulating profiled bars crimped along their two respective transverse ends in two metal sections. A transverse end of an insulating section, nested in a metal section, has a longitudinal crimping head extended by a rib itself longitudinal; the crimping head of the insulating section is arranged to be machined by teeth formed in the metal section, when it is placed in force in the latter; the crimping head of the insulating profile forms a right angle with the plane of the insulating profile itself connecting the two metal profiles. Such an assembly technique requires a significant effort for the crimping operation.

La présente invention se propose essentiellement de pallier ces inconvénients et d'apporter d'autres avantages. Plus précisément, elle consiste en un procédé de fabrication d'une barre de construction comprenant les étapes suivantes :

  • réaliser au moins une barre isolante, de type profilé, apte à être associée à une première barre métallique au moins, de type profilé, par une liaison complète, comportant une section transversale dont une première extrémité au moins est prévue pour être liée à ladite première barre métallique,
    • ladite première extrémité comportant :
      • un premier profil doté d'une forme à contre dépouille apte à être en prise dans un logement de ladite première barre métallique,
      • une première nervure prolongeant, au-delà dudit premier profil doté d'une forme à contre dépouille, ladite section transversale de ladite barre isolante apte à être disposée dans une rainure formée dans ladite première barre métallique,
      • un premier moyen longitudinal d'appui, situé en deçà dudit premier profil doté d'une forme à contre dépouille, apte à entrer en contact avec au moins une surface d'appui supplémentaire de ladite première barre métallique, située en deçà du logement pour le premier profil doté d'une forme à contre dépouille,
    • ladite première nervure possédant une section transversale complémentaire de la section transversale de ladite rainure en sorte de former une première liaison de ladite barre isolante et de ladite première barre métallique, par encastrement de ladite forme à contre dépouille et de ladite première nervure respectivement dans ledit logement et dans ladite rainure,
  • insérer ladite première extrémité de la barre isolante dans ladite première barre métallique, par encastrement de ladite forme à contre dépouille et de ladite première nervure respectivement dans ledit logement et dans ladite rainure de la première barre métallique,
  • sertir ladite barre isolante sur ladite première barre métallique au moins, afin de réaliser ladite liaison complète, en sorte que :
    • une partie, dite partie active, formant partiellement ledit logement de ladite première barre métallique soit déformée lors du sertissage, afin que ladite partie active exerce une force de sertissage sur ledit premier profil doté d'une forme à contre dépouille, de telle sorte que ladite première barre métallique exerce sur ladite barre isolante une réaction, considérée selon une section transversale desdites barres, au moins par l'intermédiaire :
      • de la rainure dans laquelle est logée ladite première nervure de la barre isolante formée au-delà du logement pour le premier profil doté d'une forme à contre dépouille, et
      • de la surface d'appui supplémentaire de ladite première barre métallique, opposée à ladite partie active et située en deçà du logement pour le premier profil doté d'une forme à contre dépouille.
The present invention essentially proposes to overcome these disadvantages and to provide other advantages. More specifically, it consists of a method of manufacturing a construction bar comprising the following steps:
  • to produce at least one insulating bar, of profiled type, suitable for being associated with at least one first metal bar, of the profiled type, by a complete connection, comprising a cross-section of which at least one first end is intended to be connected to said first metal bar,
    • said first end comprising:
      • a first profile having a form against undercut able to be engaged in a housing of said first metal bar,
      • a first rib extending beyond said first profile with an undercut shape, said cross section of said insulating bar adapted to be disposed in a groove formed in said first metal bar,
      • a first longitudinal support means, located below said first profile having a shape against undercut, adapted to come into contact with at least one additional bearing surface of said first metal bar, located below the housing for the first profile with an undercut shape,
    • said first rib having a cross-section complementary to the cross section of said groove so as to form a first connection of said insulating bar and said first metal bar, by embedding said undercut shape and said first rib respectively in said housing; and in said groove,
  • inserting said first end of the insulating bar into said first metal bar, by embedding said undercut shape and said first rib respectively in said housing and in said groove of the first metal bar,
  • crimping said insulating bar on said at least one first metal bar, in order to make said complete connection, so that:
    • a portion, said active portion, partially forming said housing of said first metal bar is deformed during crimping, so that said active portion exerts a crimping force on said first profile with a form against stripping, such that said first metal bar exerts on said insulating bar a reaction, considered in a cross section of said bars, at least through:
      • the groove in which is housed said first rib of the insulating bar formed beyond the housing for the first profile with an undercut shape, and
      • the additional support surface of said first metal bar, opposite said active portion and located below the housing for the first profile having a shape against undercut.

La première nervure de la barre isolante, apte à être associée à la rainure dans la barre métallique, combinée au profil doté d'une forme à contre dépouille apte à être associé au logement, forme une nouvelle tête d'encastrement homogène et compacte qui confère à la liaison complète entre la barre isolante et la barre métallique, une grande résistance mécanique induite par la synergie des formes, et une meilleure stabilité dimensionnelle lors de l'assemblage des barres, par exemple par sertissage, ainsi qu'une fabrication facilitée par la compacité de la tête d'encastrement. La nouvelle tête d'encastrement d'une barre isolante dans une barre métallique permet de créer de nouvelles barres de constructions dont quelques exemples de mode de réalisation seront décrits plus loin. L'appui supplémentaire entre la barre isolante et le profilé métallique, réparti en sorte d'augmenter la résistance mécanique de l'encastrement, renforce la liaison conférée par la tête d'encastrement comportant le profil à forme à contre dépouille et la nervure. L'agencement de liaison entre la barre isolante et la barre métallique permet de procéder au sertissage de la barre de construction selon l'invention au moyen d'un outil de sertissage conventionnel, par exemple une molette de sertissage, sans autre effort supplémentaire. En outre, un tel agencement offre des possibilités supplémentaires de constructions de barres comme cela sera développé plus loin avec l'aide d'exemples de modes de réalisation.The first rib of the insulating bar, adapted to be associated with the groove in the metal bar, combined with the profile having a form against undercut suitable for being associated with the housing, forms a new homogeneous and compact embedding head which confers the complete connection between the insulating bar and the metal bar, a great mechanical strength induced by the synergy of the shapes, and a better dimensional stability during the assembly of the bars, for example by crimping, and a manufacture facilitated by the compactness of the embedding head. The new embedding head of an insulating bar in a metal bar makes it possible to create new construction bars, some examples of embodiments of which will be described later. The additional support between the insulating bar and the metal section, distributed so as to increase the mechanical strength of the recess, reinforces the connection conferred by the recess head having the profile undercut shape and the rib. The connection arrangement between the insulating bar and the metal bar makes it possible to crimp the construction bar according to the invention by means of a conventional crimping tool, for example a crimping wheel, without any additional effort. In addition, such an arrangement provides additional possibilities for bar constructions as will be further developed with the aid of exemplary embodiments.

La barre de construction 10 représentée sur les figures 3 à 5, comprend une barre isolante 1, de type profilé, apte à être associée à une barre métallique 2, de type profilé, par une liaison complète, comportant une section transversale dont une première extrémité 3 est prévue pour être liée par sertissage à la barre métallique 2.The construction bar 10 shown on the Figures 3 to 5 , comprises an insulating bar 1, of profiled type, adapted to be associated with a metal bar 2, of the profiled type, by a complete connection, having a cross section whose one end 3 is intended to be crimped to the metal bar 2.

La première extrémité 3 de la barre isolante 1 comporte un profil 4 doté d'une forme à contre dépouille apte à être en prise dans un logement 5 de la barre métallique.The first end 3 of the insulating bar 1 comprises a profile 4 with a form against undercut able to be engaged in a housing 5 of the metal bar.

Selon l'invention, la section transversale de la barre isolante 1 est prolongée, au delà du profil 4 doté d'une forme à contre dépouille, par une 6 nervure apte à être disposée dans une rainure 7 de la barre métallique 2.According to the invention, the cross section of the insulating bar 1 is extended, beyond the profile 4 having a shape against undercut, by a rib adapted to be disposed in a groove 7 of the metal bar 2.

La nervure 6 possède une section transversale complémentaire de la section transversale de la rainure 7, en sorte de former une liaison de la barre isolante 1 et de la barre métallique 2, par encastrement de la forme à contre dépouille et de la 6 nervure respectivement dans le logement 5 et dans la rainure 7 de la barre métallique 2.The rib 6 has a cross section complementary to the cross section of the groove 7, so as to form a connection of the insulating bar 1 and the metal bar 2, by embedding the undercut form and the rib respectively in the housing 5 and in the groove 7 of the metal bar 2.

La première extrémité 3 de la barre isolante 1 comporte en outre un moyen 50 longitudinal d'appui, situé en deçà du profil 4 doté d'une forme à contre dépouille, apte à entrer en contact avec une surface d'appui 12 supplémentaire de la barre métallique 2, située en deçà du logement 5 pour le profil 4 doté d'une forme à contre dépouille.The first end 3 of the insulating bar 1 further comprises a longitudinal support means 50, located below the profile 4 having a form against undercut, adapted to come into contact with an additional bearing surface 12 of the metal bar 2, located below the housing 5 for the profile 4 with a shape against undercut.

La barre de construction 10 rigide obtenue après assemblage, par sertissage comme cela sera détaillé plus loin avec un exemple de mode de réalisation d'un procédé de fabrication de la barre de construction 10, de la barre isolante 1 et de la barre métallique 2, comme représenté sur la figure 5, est dans l'exemple, une barre de construction 10 dont la section transversale adopte une forme en H, une 15 des branches du H étant isolante, les trois autres, dont celle 16 en face de la branche 15 isolante, étant métalliques, la branche centrale de liaison étant également métallique. Cette forme en H comprend, comme cela apparaît sur les dessins, une forme en U définie par deux des branches du H (isolante 15 et métallique 16) pour les deux branches du U, et par la branche centrale transversale du H pour la base du U. Une utilisation d'une telle barre de construction est, par exemple, après une coupe à longueur, un montant d'ouvrant coulissant.The rigid construction bar 10 obtained after assembly, by crimping as will be detailed below with an exemplary embodiment of a method of manufacturing the construction bar 10, the insulating bar 1 and the metal bar 2, as shown on the figure 5 is, in the example, a construction bar 10 whose cross-section adopts an H-shaped shape, one of the branches of the H being insulating, the other three, including the one 16 facing the insulating branch, being metallic, the central connecting branch being also metallic. This H-shape comprises, as shown in the drawings, a U-shaped shape defined by two of the branches of the H (insulating 15 and metal 16) for the two branches of the U, and by the transverse central branch of the H for the base of the A use of such a construction bar is, for example, after a cut to length, a sash amount.

Les formes extérieures de la barre de construction 10 sont représentées à titre d'exemple sur les figures et sont par ailleurs connues ; elles ne seront donc pas décrites plus en détail ici. La zone de liaison entre la barre isolante 1 et la barre métallique, selon l'invention, va maintenant être décrite, selon l'exemple des figures 3 à 5.The outer shapes of the building bar 10 are shown by way of example in the figures and are otherwise known; they will not be described in more detail here. The connection zone between the insulating bar 1 and the metal bar, according to the invention, will now be described, according to the example of the Figures 3 to 5 .

La forme à contre dépouille adopte avantageusement une section triangulaire 40 ou sensiblement triangulaire, et le logement 5 de la barre métallique 2 adopte une section triangulaire complémentaire de la section triangulaire de la barre isolante 1, comme représenté sur la figure 4. La branche 39 de la barre isolante 1 formant la branche isolante 15 du H de la barre de construction 10, est rattachée à la section triangulaire 40 par le sommet du triangle, et la nervure 6 est rattachée à la base du triangle 40, opposée au sommet, en s'étendant avantageusement perpendiculairement à cette base, dans l'alignement ou sensiblement dans l'alignement avec la branche 39 du H, comme représenté sur la figure 3.The form undercut advantageously adopts a triangular section 40 or substantially triangular, and the housing 5 of the metal bar 2 adopts a triangular section complementary to the triangular section of the insulating bar 1, as shown in FIG. figure 4 . The branch 39 of the insulating bar 1 forming the insulating branch 15 of the H of the construction bar 10, is attached to the triangular section 40 by the vertex of the triangle, and the rib 6 is attached to the base of the triangle 40, opposite to the vertex, advantageously extending perpendicularly to this base, in alignment or substantially in alignment with the branch 39 of the H, as shown in FIG. figure 3 .

La nervure 6 de la barre isolante 1 et la rainure 7 de la barre métallique 2 adoptent avantageusement des sections respectivement complémentaires à bords droits 8, 9 parallèles.The rib 6 of the insulating bar 1 and the groove 7 of the metal bar 2 advantageously adopt respectively complementary sections with straight edges 8, 9 parallel.

La section transversale de la barre isolante 1 telle que représenté sur la figure 3 par exemple, est avantageusement constante sur la longueur de la barre, en sorte que le profil d'encastrement composé de la forme triangulaire à contre dépouille et de la nervure droite 6 est avantageusement continu sur la longueur de la barre et donc du sertissage.The cross section of the insulating bar 1 as represented on the figure 3 for example, is advantageously constant over the length of the bar, so that the embedding profile composed of the triangular shape against undercut and the right rib 6 is advantageously continuous over the length of the bar and thus the crimping.

De préférence, dans le cas de l'exemple des figures 3 à 5, la nervure 6 adopte une longueur d'extension transversale au-delà de la forme à contre dépouille, soit une longueur prise entre la base du triangle 40 et l'extrémité libre de la nervure 6, sensiblement deux fois plus grande que l'épaisseur de la nervure 6.Preferably, in the case of the example of Figures 3 to 5 , the rib 6 adopts a length of transverse extension beyond the form against undercut, ie a length taken between the base of the triangle 40 and the free end of the rib 6, substantially twice as large as the thickness of the rib 6.

L'épaisseur de la nervure 6 sera avantageusement inférieure à la base du triangle 40 en sorte que deux surfaces d'appui 41, 42 de la base de la forme triangulaire 40, de part et d'autre de la nervure 6, puissent exercer une force de pression contre des surfaces correspondantes 43, 44 de réaction sur la barre métallique 2, lors de l'opération de sertissage.The thickness of the rib 6 is advantageously less than the base of the triangle 40 so that two bearing surfaces 41, 42 of the base of the triangular shape 40, on either side of the rib 6, can exert a pressing force against corresponding surfaces 43, 44 of reaction on the metal bar 2, during the crimping operation.

L'extrémité 3 d'encastrement de la barre isolante 1 est insérée dans ses logements 5 et 7 correspondants réalisés dans la barre métallique 2, par l'extrémité longitudinale de la barre et glissement de l'une dans l'autre jusqu'à alignement des extrémités respectives des barres. L'opération de sertissage est alors effectuée par déformation de la paroi 11 longitudinale de la barre métallique 2 formant le côté extérieur du logement triangulaire 5, comme représenté sur les figures 3 et 4, au moyen d'un outil de sertissage conventionnel, par exemple à molette. La figure 4 représente la paroi 11 déformée après sertissage. Cette paroi comprend avantageusement une tête de pression en forme d'arête longitudinale qui pénètre dans le côté extérieur de la base triangulaire de la barre isolante 1, comme représenté sur la figure 4.The embedding end 3 of the insulating bar 1 is inserted in its corresponding recesses 5 and 7 made in the metal bar 2, by the longitudinal end of the bar and sliding from one to the other until alignment is achieved. respective ends of the bars. The crimping operation is then performed by deformation of the longitudinal wall 11 of the metal bar 2 forming the outer side of the triangular housing 5, as shown in FIGS. Figures 3 and 4 by means of a conventional crimping tool, for example by wheel. The figure 4 represents the wall 11 deformed after crimping. This wall advantageously comprises a pressure head in the form of a longitudinal edge which penetrates into the outer side of the triangular base of the insulating bar 1, as shown in FIG. figure 4 .

L'opération de sertissage permet de plaquer la barre isolante 1 contre la barre métallique 2, suivant deux directions d'appui perpendiculaires, définies comme suit :

  • une première direction 45 parallèle à la direction transversale définie par la branche isolante du H de la barre de construction, elle-même formée par la barre isolante 1, et
  • une deuxième direction 46 perpendiculaire à la première, et perpendiculaire au plan longitudinal défini par la branche isolante du H de la barre de construction 10, elle-même formée par la barre isolante 1.
The crimping operation makes it possible to press the insulating bar 1 against the metal bar 2, along two perpendicular bearing directions defined as follows:
  • a first direction 45 parallel to the transverse direction defined by the insulating branch of the H of the construction bar, itself formed by the insulating bar 1, and
  • a second direction perpendicular to the first and perpendicular to the longitudinal plane defined by the insulating branch of the H of the building bar 10, itself formed by the insulating bar 1.

Concernant la première force d'appui selon la première direction 45, celle-ci est assurée par les deux faces 41 et 42 de la base du triangle 40, de part et d'autre de la nervure 6, appuyant contre les surfaces 43 et 44 correspondantes, respectivement, de la barre métallique 2, qui exerce une réaction à cette première force d'appui.Regarding the first support force in the first direction 45, it is provided by the two faces 41 and 42 of the base of the triangle 40, on either side of the rib 6, pressing against the surfaces 43 and 44 corresponding, respectively, of the metal bar 2, which exerts a reaction to this first support force.

Concernant la deuxième force d'appui selon la deuxième direction 46, celle-ci est assurée par la face longitudinale 9 de la nervure 6, opposée au côté du triangle 40 sur lequel est exercée la pression de sertissage, appuyant contre la surface 47 de la rainure 7 de la barre métallique, qui exerce une réaction à cette deuxième force d'appui.Regarding the second support force in the second direction 46, it is provided by the longitudinal face 9 of the rib 6, opposite the side of the triangle 40 on which is exerted the crimping pressure, pressing against the surface 47 of the groove 7 of the metal bar, which exerts a reaction to this second support force.

Comme expliqué ci-dessus, le sertissage, grâce à l'encastrement de la barre isolante 1 dans la barre métallique 2 tel que défini selon l'invention, permet de conférer à la barre de construction 10 une grande résistance mécanique.As explained above, the crimping, thanks to the embedding of the insulating bar 1 in the metal bar 2 as defined according to the invention, makes it possible to give the construction bar 10 a high mechanical strength.

Le sertissage de la barre isolante sur la barre métallique 2, sera en outre tel que la paroi 11, dite partie active 11, formant un côté du logement 5 de la barre métallique 2 soit déformée lors du sertissage, afin que cette partie active exerce une force de sertissage sur le profil 4 doté d'une forme à contre dépouille, dans l'exemple triangulaire, de telle sorte que la barre métallique 2 exerce sur la barre isolante 1 une réaction, considérée dans le plan d'une section transversale des barres 1, 2, au moins par l'intermédiaire :

  • de la rainure 7 dans laquelle est logée la nervure 6 de la barre isolante 1 formée au-delà du logement 5 pour le premier 4 profil doté de la forme à contre dépouille avantageusement triangulaire, et plus particulièrement de la surface 47 de cette rainure 7, opposée à la partie active 11, et
  • de la surface d'appui 12 supplémentaire de la barre métallique 2, avantageusement longitudinale, située en deçà du logement 5 pour le premier 4 doté de la forme à contre dépouille, avantageusement triangulaire.
The crimping of the insulating bar on the metal bar 2, will be further such that the wall 11, said active portion 11, forming a side of the housing 5 of the metal bar 2 is deformed during crimping, so that this active part exerts a crimping force on the profile 4 having a form against undercut, in the triangular example, so that the metal bar 2 exerts on the insulating bar 1 a reaction, considered in the plane of a cross section of the bars 1, 2, at least through:
  • the groove 7 in which is housed the rib 6 of the insulating bar 1 formed beyond the housing 5 for the first 4 profile with the advantageously triangular undercut shape, and more particularly of the surface 47 of this groove 7, opposed to the active part 11, and
  • the additional bearing surface 12 of the metal bar 2, advantageously longitudinal, located below the housing 5 for the first 4 having the shape against undercut, preferably triangular.

Ces appuis sont de préférence assurés sur la longueur des barres 1 et 2.These supports are preferably provided along the length of bars 1 and 2.

Comme représenté sur la figure 4, l'arête de sertissage sur la paroi 11 exerce une force comprise entre la réaction de la rainure 7 et de la surface d'appui complémentaire 12 opposée à la paroi 11, la surface d'appui complémentaire 12 pouvant par exemple être sensiblement alignée dans le plan de la face 47 de la rainure 7. Ainsi, le moyen d'appui longitudinal 50 de la barre isolante peut être par exemple, comme représenté, constitué par une surface plane d'appui qui peut être de préférence alignée ou sensiblement alignée avec la face longitudinale 9 de la nervure 6, mais également parallèle à celle-ci. Cette répartition de l'action de sertissage et des réactions, réparties de part et d'autre de la force d'action, opposées par la barre métallique permet de renforcer la stabilité de la liaison dans le plan de la barre isolante, d'où de renforcer la stabilité de la forme géométrique en H de la barre de construction.As shown on the figure 4 , the crimping edge on the wall 11 exerts a force between the reaction of the groove 7 and the complementary bearing surface 12 opposite the wall 11, the complementary bearing surface 12 may for example be substantially aligned in the plane of the face 47 of the groove 7. Thus, the longitudinal bearing means 50 of the insulating bar may be, for example, as shown, constituted by a flat bearing surface which may preferably be aligned or substantially aligned with the longitudinal face 9 of the rib 6, but also parallel thereto. This distribution of the crimping action and the reactions, distributed on either side of the action force, opposed by the metal bar makes it possible to reinforce the stability of the connection in the plane of the insulating bar, hence to reinforce the stability of the geometric shape in H of the construction bar.

Cette surface d'appui supplémentaire 12 peut être avantageusement formée sur la barre métallique 2, longitudinalement, par une surface plane ou sensiblement plane, directement dans une zone voisine du logement 5, comme représenté sur la figure 4.This additional bearing surface 12 may advantageously be formed on the metal bar 2, longitudinally, by a flat or substantially flat surface, directly in an area close to the housing 5, as shown in FIG. figure 4 .

Bien entendu, la barre isolante 1 comportera un dégagement 48 approprié afin de permettre le déplacement de la paroi 11 au cours du sertissage, comme représenté sur la figure 4.Of course, the insulating bar 1 will have a clearance 48 appropriate to allow the displacement of the wall 11 during crimping, as shown in the figure 4 .

Un deuxième exemple de barre de construction 100 et de barre isolante 101 va maintenant être décrit à l'aide de la figure 6.A second example of construction bar 100 and insulating bar 101 will now be described using the figure 6 .

Sur cet exemple, les éléments similaires à ceux du premier exemple, assurant des fonctions similaires, sont affectés de la même référence additionnée du nombre 100. Pour ces éléments de ce deuxième exemple, il sera ainsi possible de se référer à la description du premier exemple de mode de réalisation à l'aide des figures 3 à 5.In this example, the elements similar to those of the first example, providing similar functions, are assigned the same reference plus the number 100. For these elements of this second example, it will thus be possible to refer to the description of the first example of embodiment using the Figures 3 to 5 .

La barre de construction 100 comporte une première 102 et une deuxième 122 barres métalliques connectées par une barre isolante 101 à une première 103 et une deuxième 123 extrémités de la section transversale de celle-ci, respectivement.The construction bar 100 has a first 102 and a second 122 metal bars connected by an insulating bar 101 to a first 103 and a second 123 ends of the cross-section thereof, respectively.

Les barres métalliques 102 et 122 peuvent chacune définir tout aspect extérieur approprié en fonction des besoins, et ne seront donc pas décrites plus en détail ici. Seules les interfaces de liaison avec la barre isolante 101, selon l'invention, seront détaillées.The metal bars 102 and 122 may each define any external appearance appropriate to the needs, and will not be described in more detail here. Only the connection interfaces with the insulating bar 101, according to the invention, will be detailed.

La première extrémité transversale 103 de la barre isolante est liée à la première barre métallique 102 par un encastrement similaire à celui qui est décrit dans le premier exemple, soit un encastrement comportant un profil 105 à contre dépouille avantageusement triangulaire, et une nervure 106 dans le prolongement du profil 105. Une différence avec le premier exemple, réside dans le fait que la barre métallique 101, par exemple, comprend avantageusement une première nervure supplémentaire 113 associée à une première rainure supplémentaire 114 formée dans la barre isolante 101, la première nervure supplémentaire 113 possédant une section transversale complémentaire de la section transversale de la première rainure supplémentaire 114 en sorte de former une deuxième liaison de la barre isolante 101 et de la première 102 barre métallique, par insertion ou encastrement de la première nervure supplémentaire 113 dans la première rainure supplémentaire 114.The first transverse end 103 of the insulating bar is connected to the first metal bar 102 by a recess similar to that described in the first example, that is to say a recess comprising a profile 105 advantageously triangular against undercut, and a rib 106 in the extension of the profile 105. A difference with the first example lies in the fact that the metal bar 101, for example, advantageously comprises a first additional rib 113 associated with a first additional groove 114 formed in the insulating bar 101, the first additional rib 113 having a cross section complementary to the cross section of the first additional groove 114 so as to form a second connection of the insulating bar 101 and the first metal bar 102, by insertion or embedding of the first additional rib 113 in the first groove additional 114.

De manière avantageuse, la première nervure supplémentaire 113 et la première rainure supplémentaire 114 sont formées dans une zone voisine de la première extrémité 103 de la barre isolante 101, et de préférence à proximité du profil 105 comme représenté sur la figure 6. En outre, la première nervure supplémentaire 113 et la première rainure supplémentaire 114 sont formées du côté opposé à la paroi de sertissage 111 par rapport au profil 105. Ainsi, la surface d'appui supplémentaire 112 de la première barre métallique 102 sur la barre isolante 101, située en deçà du premier profil doté d'une forme à contre dépouille, est portée par la première nervure supplémentaire 113, et plus précisément définie par la face 112 de cette nervure 113 en vis-à-vis de la paroi 111 de sertissage, comme représenté sur la figure 6.Advantageously, the first additional rib 113 and the first additional groove 114 are formed in an area close to the first end 103 of the insulating bar 101, and preferably close to the profile 105 as shown in FIG. figure 6 . In addition, the first extra rib 113 and the first additional groove 114 are formed on the opposite side to the crimping wall 111 relative to the profile 105. Thus, the additional bearing surface 112 of the first metal bar 102 on the insulating bar 101, located below the first profile provided with of a form against undercut, is carried by the first additional rib 113, and more precisely defined by the face 112 of the rib 113 vis-à-vis the crimping wall 111, as shown in the figure 6 .

Ainsi, à l'instar du premier exemple, l'arête de sertissage sur la paroi 111 exerce une force comprise entre la réaction de la rainure 107 et de la surface d'appui complémentaire 112 opposée à la paroi 111, la surface d'appui complémentaire 112 pouvant par exemple être sensiblement alignée dans le plan de la face d'appui de la rainure 107. Ainsi, le moyen d'appui longitudinal 150 de la barre isolante 101 peut être par exemple, comme représenté, constitué par la surface plane d'appui de la première rainure supplémentaire 114, qui peut être de préférence alignée ou sensiblement alignée avec la face longitudinale 109 de la nervure 106, mais également parallèle à celle-ci. Cette répartition de l'action de sertissage et des réactions, réparties de part et d'autre de la force d'action, opposées par la barre métallique, permet de renforcer la stabilité de la liaison dans le plan de la barre isolante, d'où de renforcer la stabilité de la barre de construction.Thus, like the first example, the crimping edge on the wall 111 exerts a force between the reaction of the groove 107 and the complementary bearing surface 112 opposite the wall 111, the bearing surface complementary device 112 may for example be substantially aligned in the plane of the bearing face of the groove 107. Thus, the longitudinal support means 150 of the insulating bar 101 may be, for example, as shown, constituted by the flat surface of supporting the first additional groove 114, which may preferably be aligned or substantially aligned with the longitudinal face 109 of the rib 106, but also parallel thereto. This distribution of the crimping action and the reactions, distributed on either side of the action force, opposed by the metal bar, makes it possible to reinforce the stability of the connection in the plane of the insulating bar. where to strengthen the stability of the construction bar.

Dans le cas de la figure 6, la barre isolante 101 comporte par exemple un profilé alvéolaire définissant deux parois 135, 136 de liaison entre les première 102 et deuxième 122 barres métalliques, ce qui constitue une autre différence avec le premier exemple. La barre de liaison 101 comporte ainsi une première extrémité 103 reliant ces deux parois 135 et 135, par l'intermédiaire d'un voile perpendiculaire aux parois 135 et 136, dans lequel sont formés la rainure 114 et le profil 105 à contre dépouille muni de la nervure de prolongement 106, et dont une partie peut être en appui contre la première barre métallique. Les nervures 106 et 113 sont avantageusement parallèles afin de définir des faces d'appui parallèles lors du sertissage.In the case of figure 6 , the insulating bar 101 comprises for example a cellular section defining two walls 135, 136 connecting between the first 102 and second 122 metal bars, which is another difference with the first example. The connecting bar 101 thus has a first end 103 connecting these two walls 135 and 135, via a web perpendicular to the walls 135 and 136, in which are formed the groove 114 and the profile 105 against undercut provided with the extension rib 106, and a part of which may bear against the first metal bar. The ribs 106 and 113 are advantageously parallel so as to define parallel bearing faces during crimping.

Dans le cas de la figure 6, ce qui constitue une autre différence avec le premier exemple, il est possible d'envisager que la nervure 106 puisse être réduite à une longueur nulle, ses effets étant alors remplacés par ceux de la nervure 113 associée à la rainure 114. Cependant, une telle configuration est moins résistante que lorsque la nervure 106 est présente et possède par exemple, comme représenté, une longueur sensiblement égale à son épaisseur.In the case of figure 6 , which is another difference with the first example, it is possible to envisage that the rib 106 can be reduced to zero length, its effects then being replaced by those of the rib 113 associated with the groove 114. However, a such a configuration is less resistant than when the rib 106 is present and has for example, as shown, a length substantially equal to its thickness.

Sur la deuxième extrémité 123 de la barre isolante 101, la liaison complète avec la deuxième barre métallique 122 est assurée de manière conventionnelle, à titre d'exemple comparatif, grâce à deux têtes triangulaires de sertissage conventionnelles telles que décrites plus haut relativement à la description de l'art antérieur, avec l'aide des figures 1 et 2.On the second end 123 of the insulating bar 101, the complete connection with the second metal bar 122 is provided in a conventional manner, by way of a comparative example, by means of two conventional triangular crimping heads as described above with respect to the description. of the prior art, with the help of Figures 1 and 2 .

Il y a lieu de noter que, de manière avantageuse, la liaison complète par sertissage, selon l'invention, entre la première extrémité 103 de la barre isolante 101 et le premier profilé métallique 102, comporte une seule paroi de sertissage 111, alors que la liaison complète par sertissage, conventionnelle, entre la deuxième extrémité 123 de la barre isolante 101 et le deuxième profilé métallique 122, comporte deux parois de sertissage, une pour chaque tête conventionnelle. La liaison selon l'invention permet ainsi de diminuer avantageusement le nombre de sertissages pour associer une barre isolante alvéolaire à une barre métallique, tout en obtenant une résistance mécanique et un dimensionnement géométrique de la barre de construction ainsi obtenue, au moins égaux, et même supérieur en ce qui concerne le dimensionnement géométrique du fait de la réduction des sertissages donc des déformations induites.It should be noted that, advantageously, the complete connection by crimping, according to the invention, between the first end 103 of the insulating bar 101 and the first metal profile 102, comprises a single crimping wall 111, whereas the complete connection by crimping, conventional, between the second end 123 of the insulating bar 101 and the second metal section 122, has two crimping walls, one for each conventional head. The connection according to the invention thus makes it possible to advantageously reduce the number of crimps to associate a cellular insulating bar with a metal bar, while obtaining a mechanical strength and a geometric dimensioning of the construction bar thus obtained, at least equal, and even superior in geometrical dimensioning due to the reduction of crimps and induced deformations.
