Abstract

La présente invention concerne la structure constructive finale d'une poutre porteuse pour train à sustentation magnétique. Cette poutre porteuse comprend une structure porteuse principale (1) et une structure fonctionnelle plane en couche supérieure (2) posée sur la structure porteuse principale (1). La structure fonctionnelle plane en couche supérieure (2) comprend une structure de poutres transversales (40) reliant entre elles les poutres porteuses adjacentes, une plateforme montée sur rails (20) posée sur la structure porteuse principale (1), et une poutre porteuse en plaque (30) posée sur la plateforme montée sur rails (20). La structure comporte également des supports réglables (11) placés en dessous de l'extrémité de poutre de la structure porteuse principale (1). Ces supports réglables permettent un transfert de force et un réglage en hauteur conférant à l'ensemble constituant la poutre des bonnes qualités d'adaptation et de coordination. Le recours à la structure de poutre transversale permet d'être moins exigeant quant à la précision, et de faciliter la construction de la structure porteuse, tout en augmentant les possibilités d'adaptation aux irrégularités d'implantation du pilier.
