Abstract

L'invention concerne un dispositif de mise sous tension et de verrouillage automatique de mêmes groupes de barres uniques comprenant une poutre de mise sous tension et une pluralité de modules de mise sous tension agencés en parallèle, chaque module de mise sous tension comprenant un vérin et une tige de mise sous tension, le vérin étant monté à l'intérieur de la poutre de mise sous tension, la partie inférieure du vérin étant fixée à la poutre de mise sous tension, la partie supérieure du vérin étant raccordée à une extrémité de la tige de mise sous tension, l'autre extrémité de la tige de mise sous tension s'étendant hors de la poutre de mise sous tension, le module de mise sous tension étant également doté d'un capteur de mesure de force. Les effets bénéfiques de la présente invention sont les suivants : la solution technique réalise simultanément une mise sous tension synchrone de barres d'acier précontraint uniques, des capteurs indépendants de barre unique commandent une force de mise sous tension et la force de mise sous tension est automatiquement verrouillée une fois qu'une mise sous tension automatique a été réalisée de sorte qu'une valeur de force de mise sous tension soit uniforme, stable et à erreur réduite, une machinerie automatique remplace des opérations manuelles, la précision du travail et le rendement de production sont augmentés et les coûts de production sont réduits.
