Tank including a corner anchor element

A sealed and thermally-insulating tank intended to be installed in a supporting structure to store liquefied gas, comprising:

• a first tank wall and a second tank wall joining at a level of an edge and respectively extending in a first median plane and a second median plane inclined relative to one another so as to form at a level of a junction between the first tank wall and the second tank wall a corner zone,
• the first tank wall including in a first direction of thickness of the first tank wall from an exterior to an interior of the sealed and thermally-insulating tank:
• a first underlying thermally-insulating barrier and a first underlying sealed membrane supported by the first underlying thermally-insulating barrier, and
• a first thermally-insulating barrier and first sealed membrane supported by the first thermally-insulating barrier
• the second tank wall including in a second direction of thickness of the second tank wall, from the exterior to the interior of the sealed and thermally-insulating tank:
• a second underlying thermally-insulating barrier and a second underlying sealed membrane supported by the second underlying thermally-insulating barrier, and
• a second thermally-insulating barrier and a second sealed membrane supported by the second thermally-insulating barrier,
• the first sealed membrane and the second sealed membrane being fixed in a sealed manner to a corner anchor strip along the edge
• a corner anchor rod extending in a direction that crosses a direction of the edge formed between the first tank wall and the second tank wall in an extension plane passing through the edge inclined at a non-zero angle relative to each of the first tank wall and the second tank wall,
• an anchor bar extending in a plane perpendicular to a direction of the corner anchor rod and anchored to a support, the support being an element of the underlying sealed membrane,
• a first end of the corner anchor rod cooperating with the anchor bar and a second end of the corner anchor rod cooperating with the corner anchor strip to transmit a traction force between the corner anchor strip and the support.
