Uncoupling of the corrugations of an impervious barrier

摘要

The invention relates to a sealed, thermally insulated vessel comprising a vessel wall on a bearing structure (2), the vessel wall including an insulating barrier (1), an impervious barrier (4) and an anchoring member (3), the impervious barrier comprising: a first corrugated metal membrane (5) arranged on a first portion of the insulating barrier, a second corrugated metal membrane (6) arranged on a second portion of the insulating barrier, located on either side of the anchoring member, along an assembly edge arranged parallel to a longitudinal direction of the anchoring member (3), the first and second membranes being corrugated with a first series of corrugations intersecting the edge for assembling the end corrugation portions associated with the first series of corrugations of the first membrane extending in a direction transverse to the assembly edge in the direction of the second membrane, beyond the end corrugation portions associated with the first series of corrugations of the second membrane.
