Abstract

Carter combiné pour ligne de production, comprenant des poutres supérieures et inférieures et des colonnes indépendantes les unes des autres, les poutres supérieures et inférieures et les colonnes étant reliées par un dispositif de connexion de manière à former un carter combiné. Le carter combiné pour ligne de production de l'invention facilite la fabrication, le transport et l'installation sur site du carter, réduisant ainsi les coûts de traitement, de fabrication, de transport et d'installation du carter. Dans le carter combiné pour ligne de production de l'invention, les contraintes de compression auxquelles sont soumises les colonnes peuvent être régulées durant le processus d'assemblage, la rigidité globale du carter peut donc être augmentée. Dans un autre aspect de l'invention, le carter combiné est doté de dispositifs d'équilibrage des moments qui appliquent aux parois latérales des poutres des moments de sens opposé à celui des moments auxquels sont soumises les parois latérales correspondantes durant le fonctionnement de la ligne de production.
