Definitions
- 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 .
- 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.
- FIG. 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.

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.

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
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
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
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
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
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

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
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
