The invention relates to a method for making the wall of a heat-insulated fluid-confinement tank, such as for a liquefied gas, that is integrated in the carrier structure (50) of a ship, wherein a prefabricated substantially rectangular block (25) is assembled on top of a flexible mat strip (35), th
The invention relates to a method for making the wall of a heat-insulated fluid-confinement tank, such as for a liquefied gas, that is integrated in the carrier structure (50) of a ship, wherein a prefabricated substantially rectangular block (25) is assembled on top of a flexible mat strip (35), the assembling of said block comprising the following steps: applying two longitudinal parallel strips of glue (26, 26′) on the lower surface of said block (25), said strips (26, 26′) being separated by a glue-free central longitudinal space (28); gluing said glued block (25) on a flexible mat strip (35) by pressing said glued block (25) on said flexible mat strip (35) so that after gluing, said longitudinal central space (28) is at least partially filled with glue, thus defining a substantially continuous glue layer on the lower surface of the block (25), said substantially continuous glue layer reinforcing the gluing of said flexible mat strip (35) in order to ensure tightness.

1. 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, andb. 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). 2. A method according to claim 1 in which, during application, the thickness of each longitudinal adhesive strip (26, 26′) is between 3 and 4 mm. 3. A method according to claim 1 in which, during application, the width of each longitudinal adhesive strip (26, 26′) is between 90 and 110 mm. 4. A method according to claim 3, in which said width is about 100 mm. 5. A method according to claim 1 in which, for a standard baseplate (25) whose tank side area is 1000 mm×250 mm, the total quantity of adhesive is between 765 g and 935 g. 6. A method according to claim 1 in which, for a standard baseplate (25) whose tank side area is 720 mm×250 mm, the total quantity of adhesive is between 550 g and 670 g. 7. A method according to claim 1 in which, before the gluing step, the width of the longitudinal central space (28) is between 10 mm and 20 mm. 8. A method according to claim 1 in which, after the gluing step, from at least 50% to, 75% of the initial area of the longitudinal central space (28) is filled with adhesive. 9. A method according to claim 1 in which the adhesive used to glue the baseplates (25) onto the flexible sheet strips (35) is a polymerizable adhesive of the two-component epoxy type. 10. A method according to claim 1, in which said fluid product is a liquefied gas.
