Abstract

La présente invention concerne un coupleur de raccordement de barre d'armature et son procédé de fabrication, le coupleur de raccordement de barre d'armature comprenant : un corps qui présente la forme d'un corps creux sur le bord périphérique extérieur duquel un filetage est formé de façon à raccorder une paire de barres d'armature l'une à l'autre sur un chantier de construction ; et des écrous de fixation qui présentent la forme de corps creux, qui sont accouplés par vis aux deux extrémités du corps, respectivement, et qui ont des bords périphériques intérieurs formés de telle sorte que leurs diamètres intérieurs diminuent vers leurs deux extrémités, des éléments de fixation qui présentent la forme de corps creux étant insérés dans les écrous de fixation qui sont accouplés par vis aux deux extrémités du corps, respectivement. Plus particulièrement, la présente invention concerne un coupleur de raccordement de barre d'armature et son procédé de fabrication, caractérisé en ce que les éléments de fixation sont des manchons qui présentent la forme de corps creux, dont les diamètres extérieurs diminuent vers leurs deux extrémités, et qui comportent une pluralité de rainures de guidage formées le long de la direction circonférentielle des manchons et allongées dans la direction longitudinale des manchons ; les rainures de guidage comportent des ouvertures près de l'une des deux extrémités des manchons, qui possède un diamètre plus petit ; des éléments d'entrée en prise sont insérés dans les rainures de guidage, respectivement ; chaque élément d'entrée en prise comprend un élément plaque qui est fait d'un matériau métallique, et sur une surface duquel des rebords d'entrée en prise sont formés sous forme de dents de scie, et des parties de guidage faites d'un matériau en résine synthétique et formées de façon monobloc sur les deux surfaces de l'élément plaque ; et les éléments d'entrée en prise sont fabriqués par injection à pièce rapportée. Le coupleur de raccordement de barre d'armature selon la présente invention est sensiblement avantageux en ce qu'il présente une structure simple et est donc facile à fabriquer, ses coûts de fabrication sont faibles, et le temps de travail de fixation nécessaire pour raccorder les barres d'armature peut être raccourci.
