Sealed and thermally insulating tank

A sealed and thermally insulating tank incorporated into a polyhedral bearing structure, the tank comprising a plurality of tank walls, the tank walls comprising a thermally insulating barrier anchored on first and second bearing walls of the bearing structure and a sealed membrane borne by said thermally insulating barrier, wherein the first bearing wall (2) and the second bearing wall (3) form an edge corner (1) of the bearing structure,

• the thermally insulating barrier of a first tank wall comprising a row of edging blocks (5) anchored on the first bearing wall (2) and juxtaposed along the edge corner (1) in such a way as to form a first support surface parallel to the first bearing wall (2),
• the tank comprising a row of anchor strips (45) extending parallel to the edge corner (1), said anchor strips (45) being borne by the first support surface and anchored to the second bearing wall (3) by a row of anchor rods (12), an end portion of the sealed membrane of the first tank wall turned towards the edge corner (1) being fixed on said row of anchor strips,
• a first and a second of said edging blocks (5) each comprising a groove (32) formed in a thickness of said edging block (5) from an upper face of said edging block (5) in such a way as to form a space accessible from the second bearing wall (3) in the edging block, a first one and a second one of said anchor rods (12) being housed respectively in the groove (32) of the first and second edging blocks (5), said first and second anchor rods extending from the second bearing wall (3) across a thickness of the thermally insulating barrier of the second tank wall, said first and second anchor rods each comprising a first end anchored to the second bearing wall (3) and a second end opposite the first end and coupled to the row of anchor strips (45) in order to transmit a tensile load between the row of anchor strips (45) and the second bearing wall (3),
• wherein the first end of each of the first and second anchor rods is housed in a first hollow cylindrical base, wherein the first hollow cylindrical base is welded to the second bearing wall,
• wherein an anchor strip (45) of the row of anchor strips (45) is overlapping the first edging block (5) and the second edging block (5), said anchor strip (45) comprising a first tab and a second tab projecting respectively from two opposite end portions of the anchor strip (45) towards the first bearing wall (2), the first and second tabs being engaged respectively in the groove (32) of the first edging block (5) and of the second edging block (5) and being respectively coupled to the first anchor rod (12) and to the second anchor rod (12).
