Abstract
A watertight and thermally insulating tank built into a bearing structure includes at least one wall having a variable width and forming oblique solid angles of intersection with the adjacent walls, the tank includes secondary insulating and watertightness barriers and a primary insulating barrier which are formed by panels fixed to the walls and able to hold a primary watertightness barrier. The primary water-tightness barrier includes, at each variable-width wall, one or more central strake(s) (63) arranged longitudinally and each fixed to underlying panels (12), running strakes (66) being held mechanically, by a sliding joint, parallel to the oblique solid angles of intersection, on underlying panels and fixed at the ends to the central strakes, so that the tensile forces (F) experienced by the running strakes in their longitudinal dimension are transmitted to the bearing structure via the central strakes.
