Patent ID: 7464658

Claim:
Sealed, thermally insulated tank including at least one tank wall fixed to the load-bearing structure ( 1 ) of a floating structure, said tank wall having, in succession, in the direction of the thickness from the inside to the outside of said tank, a primary sealing barrier ( 8 ), a primary insulating barrier ( 6 ), a secondary sealing barrier ( 5 ) and a secondary insulating barrier ( 2 ), at least one of said insulating barriers consisting essentially of juxtaposed non-conducting elements ( 3 , 7 ), each non-conducting element including a thermal insulation liner arranged in the form of a layer parallel to said tank wall, at least one panel ( 10 , 11 ) extending parallel to said tank wall over at least one side of said thermal insulation liner and load-bearing partitions projecting from a face of said at least one panel facing said thermal insulation liner, said load-bearing partitions rising through the thickness of said thermal insulation liner in order to take up compression forces, characterized in that said load-bearing partitions include at least one anti-buckle partition ( 14 , 114 , 214 , 314 , 414 , 514 , 614 , 714 , 814 ) that, seen in cross section in a plane parallel to said at least one panel, has a general longitudinal direction (A) and includes a plurality of anti-buckle wall elements ( 25 , 125 , 225 a - b , 325 a , 425 c - d , 566 , 666 , 766 , 866 , 825 ) that have a respective orientation forming an angle relative to said general longitudinal direction (A) of the anti-buckle partition.
