Abstract

L'unité de production consiste en une série de barres multi-fonctions mobiles enjambant transversalement le banc, lequel est constitué de moules ayant une ouverture, ainsi qu'en un dispositif d'ancrage situé dans un plan de cote supérieure à celle du plan des moules. The production unit consists of a series of bars multi-function mobile transversely spanning the bench, which consists of molds having an opening, as well as an anchoring device located in a dimension plan greater than that of the mold plan.

Les barres multi-fonctions comportent sur leur longueur une série de crochets correspondant à la série de moules. Sa commande hydraulique permet une automatisation du cycle de production : enchaínement séquential de la descente des crochets, du positionnement des aciers, du coffrage des extrémités des poutrelles ; de même, levage, retournement des poutrelles ; de même, dépose, retour en position haute de départ. Multi-function bars have along their length a series of hooks corresponding to the series of molds. Her hydraulic control allows cycle automation of production: sequential sequence of the descent of hooks, positioning of steels, formwork ends of beams; similarly, lifting, turning beams; similarly, removal, return to high position of departure.

Outre l'automatisation, le procédé présente un démou­ lage qui utilise la détention des aciers par suppression du tendeur qui appuie sur leur tronçons hors-moule. Les poutrelles produites peuvent présenter une dépouille néga­ tive grâce à l'ouverture des moules dont les flancs sont articulés à leur base. In addition to automation, the process presents a demou lage which uses the detention of steels by removing the tensioner which presses their out-of-mold sections. The beams produced can present a negative draft thanks to the opening of the molds whose sides are articulated at their base.
