Abstract (en)
[origin: WO2020221566A1] The invention relates to a corner piece (2) for constructing a sealing membrane (3) for a vessel, the corner piece (2) comprising a first panel (11) and a second panel (12), which are at an angle α to each other of between 1° and 179° and join at a folding line (13), the corner piece (2) comprising a corrugation (17) intersecting the folding line (13) and extending from one end of the corner piece (2) to the other, the corrugation (17) comprising: - a first portion (18) arranged in the first panel (11); - a second portion (19); - a central portion (20) formed astride the first panel (11) and the second panel (12); - the central portion (20) having, in a section taken in a plane passing through the folding line (13), a profile in the shape of an inverse W having one concave depression (24) and two convex protuberances (22, 23) arranged transversally on either side of the concave depression (24).
