Patent ID: 8444803

Claim:
A method for the creation of a wall for a heat-insulated tank for the containment of a fluid product incorporated into the bearing structure ( 50 ) of a ship, where the wall includes a primary sealing membrane ( 10 ) to contact the product contained in the tank, a primary thermal insulation barrier ( 20 ), a secondary sealing membrane ( 30 ) and a secondary thermal insulation barrier ( 40 ) connected to the bearing structure ( 50 ), where the secondary sealing membrane ( 30 ) and the secondary thermal insulation barrier ( 40 ) are formed by the assembly of prefabricated panels placed side-by-side, with an empty space ( 45 ) between two adjacent panels and a flexible sheet strip ( 35 ) being glued in a channel ( 24 ) above the empty space ( 45 ) between two adjacent panels in order to ensure the continuity of the secondary seal ( 30 ), where the primary thermal insulation barrier ( 20 ) is formed by the assembly of prefabricated panels placed onto panels to form a channel ( 24 ) above each empty space ( 45 ), whereby a generally rectangular prefabricated baseplate ( 25 ) is assembled in each channel ( 24 ) above each flexible sheet strip ( 35 ), characterised in that the assembly of the baseplate ( 25 ) includes the following: a. application of two parallel longitudinal adhesive strips ( 26 , 26 ′) onto the bottom surface of the baseplate ( 25 ), the strips ( 26 , 26 ′) being separated by a longitudinal central space ( 28 ) with no adhesive, and b. gluing the glue-treated baseplate ( 25 ) in a channel ( 24 ) onto a flexible sheet strip ( 35 ), by pressure of the said baseplate ( 25 ) onto the flexible sheet strip ( 35 ), so that after gluing, the longitudinal central space ( 28 ) is at least partially filled with adhesive, thereby forming a substantially continuous adhesive layer on the bottom surface of the baseplate ( 25 ), which reinforces the gluing of the flexible sheet strip ( 35 ) in order to effect the seal of the secondary sealing membrane ( 30 ).
