Abstract

La présente invention concerne un système de précontrainte au moyen d'un assemblage à vis, comprenant: une poutre (100) installée dans une structure dans une direction où elle subira un moment de flexion; des unités de fixation (200), dont chacune comporte une partie terminale articulée (210) et qui sont formées respectivement aux deux extrémités de la poutre (100); une pluralité d'éléments en saillie (300) dont chacun comporte une partie centrale articulée (310) et saille vers l'extérieur depuis la poutre (100); une pluralité d'éléments de charnière (400), dont chacun comporte une extrémité reliée par articulation à un côté de la partie terminale articulée (210) et reliée par articulation aux deux côtés de la partie centrale articulée (310); et une pluralité d'éléments d'assemblage (500) assemblés par vis aux autres extrémités des éléments de charnière (400). Le système de précontrainte selon la présente invention est installé de telle manière que la ligne formée en reliant les éléments de charnière (400) et les éléments d'assemblage (500) est courbe ou courbée pour permettre à la partie médiane de la liaison de faire saillie le plus loin de la poutre (100) et la force de précontrainte est appliquée à la poutre (100) par l'assemblage à vis des éléments d'assemblage (500). Le système selon la présente invention permet la remise en tension et la réutilisation de composants et permet d'effectuer facilement la mise en œuvre et l'installation des extrémités des éléments de mise sous tension.
