Abstract (en)

[origin: WO2020012084A1] The invention concerns a tank wall (1) comprising a thermally insulating barrier (2) and a sealing membrane (3) resting on the thermally insulating barrier (2), the sealing membrane (3) comprising a corrugation having a curvilinear portion (36) developing in a curvilinear direction (d1) and at least one curvilinear reinforcement device (37) arranged inside the curvilinear portion (36), between the sealing membrane (3) and the thermally insulating barrier (2), in such a way as to reinforce said curvilinear portion (36), said curvilinear reinforcement device (37) comprising a plurality of reinforcement sections (42, 43, 44) that each have a profiled shape developing in a straight direction (d2, d3, d4), the curvilinear reinforcement device (37) further comprising a connection member (45) connecting said reinforcement sections (42, 43, 44) in such a way as to keep them in a position in which the straight direction (d2, d3, d4) of each of the reinforcement sections (42, 43, 44) is oriented tangentially to the curvilinear direction (d1).
