Abstract

Sealed and thermally insulating tank incorporated into a polyhedral bearing structure, a first bearing wall and a second bearing wall forming an edge corner, the tank having a first tank wall, a thermally insulating barrier and a sealed membrane, the tank further has an angle bracket with a first flange and a second flange in such a way that the angle bracket connects in a sealed manner. The sealed membrane of the first tank wall and the sealed membrane of the second tank wall in line with the edge corner, in which the angle bracket has a pair of first tabs and a pair of second tabs, the tank has a pair of first anchor rods coupled to a respective first tab and a pair of second anchor rods coupled to a respective second tab in such a way as to transmit a tensile load between the angle bracket.

First claim

The invention claimed is:

1. A sealed and thermally insulating tank incorporated into a polyhedral bearing structure, a first bearing wall ( 2 ) of the bearing structure and a second bearing wall ( 3 ) of the bearing structure forming an edge corner ( 1 ) of the bearing structure, the tank comprising a first tank wall anchored on the first bearing wall and a second tank wall anchored on the second bearing wall, the tank walls comprising a thermally insulating barrier anchored on the corresponding bearing wall and a sealed membrane borne by said thermally insulating barrier,
the tank further comprising an angle bracket ( 9 ), the angle bracket ( 9 ) comprising a first flange ( 10 ) borne by the thermally insulating barrier of the first tank wall and a second flange ( 11 ) borne by the thermally insulating barrier of the second tank wall, an end portion of the sealed membrane of the first tank wall turned towards closest to the edge corner ( 1 ) being fixed in a sealed manner to the first flange ( 10 ) of the angle bracket ( 9 ) and an end portion of the sealed membrane of the second tank wall turned towards closest to the edge corner ( 1 ) being fixed in a sealed manner to the second flange ( 11 ) of the angle bracket ( 9 ) in such a way that the angle bracket ( 9 ) connects in a sealed manner the sealed membrane of the first tank wall and the sealed membrane of the second tank wall in line with the edge corner ( 1 ),
in which the angle bracket ( 9 ) comprises a pair of first tabs ( 33 ) each projecting from a respective end portion of the first flange ( 10 ) in the direction of toward the first bearing wall ( 2 ) and a pair of second tabs ( 33 ) each projecting from a respective end portion of the second flange ( 11 ) in the direction of toward the second bearing wall ( 3 ),
the tank comprising a pair of first anchor rods ( 12 ) each comprising a first end and a second end opposite the first end, said first end being anchored to the second bearing wall ( 3 ) and said second end being coupled to a respective first tab ( 33 ) of the pair of first tabs ( 33 ), one said first anchor rod ( 12 ) extending from the second bearing wall ( 3 ) in the direction of toward the corresponding first tab ( 33 ) in order to transmit a tensile load between the angle bracket ( 9 ) and the second bearing wall ( 3 ) and retain the angle bracket ( 9 ) on the thermally insulating barrier,
the tank further comprising a pair of second anchor rods ( 12 ) each comprising a first end and a second end opposite the first end, said first end being anchored on the first bearing wall ( 2 ) and said second end being coupled to a respective second tab ( 33 ) of the pair of second tabs ( 33 ), one said second anchor rod ( 12 ) extending from the first bearing wall ( 2 ) in the direction of toward the corresponding respective second tab ( 33 ) in order to transmit a tensile load between the angle bracket ( 9 ) and the first bearing wall ( 2 ) and retain the angle bracket ( 9 ) on the thermally insulating barrier,
wherein the flanges and the tabs of the angle bracket are assembled by welding or formed from a single element in such a way that the angle bracket (9) is one-piece, and wherein each tab of the pair of first tabs is coplanar with a corresponding tab of the pair of second tabs.

2. The sealed and thermally insulating tank according to claim 1 , in which the flanges ( 10 , 11 ) and the tabs ( 33 ) of the angle bracket ( 9 ) are formed from a single element in such a way that the angle bracket ( 9 ) is one-piece.

3. The sealed and thermally insulating tank according to claim 1 , in which one said first tab ( 33 ) projects from a lower face of the first flange ( 10 ) facing the first bearing wall ( 2 ) at a distance from a lateral edge of the first flange ( 10 ) of the angle bracket ( 9 ) forming one end of the first flange ( 9 ), and in which one said second tab ( 33 ) projects from a lower face of the second flange ( 11 ) facing the second bearing wall ( 3 ) at a distance from a lateral edge of the second flange ( 11 ) of the angle bracket ( 9 ) forming one end of the second flange ( 11 ).

4. The sealed and thermally insulating tank according to claim 1 , in which a longitudinal edge of the first flange ( 10 ) parallel to the edge corner ( 1 ) projects beyond the first tabs ( 33 ) in a direction perpendicular to the second bearing wall ( 3 ) in such a way that said longitudinal edge of the first flange ( 10 ) is further from the second bearing wall ( 3 ) than said first tabs ( 33 ) in said direction perpendicular to the second bearing wall ( 3 ), and in which a longitudinal edge of the second flange ( 11 ) parallel to the edge corner ( 1 ) projects beyond the second tabs ( 33 ) in a direction perpendicular to the first bearing wall ( 2 ) in such a way that said longitudinal edge of the second flange ( 11 ) is further from the first bearing wall ( 2 ) than said second tabs ( 33 ) in said direction perpendicular to the first bearing wall ( 2 ).

5. The sealed and thermally insulating tank according to claim 1 , A sealed and thermally insulating tank incorporated into a bearing structure, a first bearing wall (2) of the bearing structure and a second bearing wall (3) of the bearing structure forming an edge corner (1) of the bearing structure, the tank comprising a first tank wall anchored on the first bearing wall and a second tank wall anchored on the second bearing wall, the tank walls comprising a thermally insulating barrier anchored on the corresponding bearing wall and a sealed membrane borne by said thermally insulating barrier,
