Abstract
L'invention concerne un système de mise en tension et de détension de câbles de précontrainte pour la fabrication de poutrelles ou produits analogues. Ce système comprend un bâti mobile agencé dans une fosse délimitée par un massif à une extrémité des pistes, des moyens de guidage du bâti en translation longitudinale dans la fosse, des peignes de rétention des câbles, fixés sur le bâti mobile, des moyens d'entraînement du bâti mobile en translation longitudinale tels que vérin hydraulique, et une cale de blocage mobile verticalement, située l'avant de la fosse. Le système conforme à l'invention bénéficie d'un encombrement réduit, et ne dépasse pas du niveau des pistes ; il permet de réaliser simultanément la détension de tous les câbles de précontrainte.
