Panel wave of the bottom of the electric transformer immersed, the method of implementation, and its application to the mounting of a vessel.

摘要

P on a panel wave 3 ′ a of the aforementioned type, and provided with an end portion 9 'to constitute a wave - mother 11 ′ for sealed assembly with the end downpour 10 ′ of the panel wave adjacent 3 ′ of the corrugations 8, the invention consists in providing this end portion 9 ′ of secondary waves of rigidity, 16, which may advantageously be formed by folds formed in the same time as the main waveguide 8 on the same tool. / p
