The tank as claimed in claim 1, wherein the first and second panels each comprise an inner plywood sheet and an outer plywood sheet, forming the inner surface and the outer surface, respectively, of said first and second panels, and a layer of insulating polymer foam sandwiched between said inner and outer plywood sheets. 3. The tank as claimed in claim 2, wherein the lateral edge of the first panel, resting against the second wall, is provided with a plywood sheet. 4. The tank as claimed in claim 3, wherein the thermal insulating barrier is a secondary thermal insulating barrier, and the sealing membrane is a secondary sealing membrane, the tank further comprising a primary thermal insulating barrier and a primary sealing membrane. 5. The sealed tank as claimed in claim 4, wherein the primary thermal insulating barrier comprises, at the intersection between the first and the second wall of the support structure, a corner structure comprising a first and a second primary thermal insulating panel, each having an outer surface positioned facing the secondary sealing membrane, an inner surface provided with a member for securing the primary sealing membrane, and lateral edges, the first primary thermal insulating panel having a lateral edge resting against the second sealing membrane, and the second primary thermal insulating panel having a lateral edge resting against the inner surface of the first primary thermal insulating panel. 6. The tank as claimed in claim 2, wherein the thermal insulating barrier is a secondary thermal insulating barrier, and the sealing membrane is a secondary sealing membrane, the tank further comprising a primary thermal insulating barrier and a primary sealing membrane. 7. The tank as claimed in claim 6, wherein the pins for fastening the primary thermal insulating barrier extend in the axis of one of the metal connecting strips, and the edges of the metal plates welded to the metal connecting strips and/or to the angle piece and the edges of the angle piece welded to the metal connecting strips and/or to edges of the metal plates welded to said metal connecting strips are provided with cut-outs for the passage of the pins for fastening the primary thermal insulating barrier. 8. The sealed tank as claimed in claim 6, wherein the primary thermal insulating barrier comprises, at the intersection between the first and the second wall of the support structure, a corner structure comprising a first and a second primary thermal insulating panel, each having an outer surface positioned facing the secondary sealing membrane, an inner surface provided with a member for securing the primary sealing membrane, and lateral edges, the first primary thermal insulating panel having a lateral edge resting against the second sealing membrane, and the second primary thermal insulating panel having a lateral edge resting against the inner surface of the first primary thermal insulating panel. 9. The tank as claimed in claim 1, wherein the outer surface of the first panel resting against the first wall, the lateral edge of the first panel resting against the second wall, and the outer surface of the second panel resting against the second wall are glued to the support structure. 10. The tank as claimed in claim 9, wherein the thermal insulating barrier is a secondary thermal insulating barrier, and the sealing membrane is a secondary sealing membrane, the tank further comprising a primary thermal insulating barrier and a primary sealing membrane. 11. The tank as claimed in claim 1, wherein a metal connecting strip is retained in a recess formed on the inner surface of the first or second panel, and is fitted in said recess with a sliding clearance j in a direction transverse to the direction of said metal connecting strip, so as to allow the metal connecting strip to move in the plane of the first or the second panel respectively. 12. The tank as claimed in claim 11, wherein the thermal insulating barrier is a secondary thermal insulating barrier, and the sealing membrane is a secondary sealing membrane, the tank further comprising a primary thermal insulating barrier and a primary sealing membrane. 13. The tank as claimed in claim 1, wherein the thermal insulating barrier is a secondary thermal insulating barrier, and the sealing membrane is a secondary sealing membrane, the tank further comprising a primary thermal insulating barrier and a primary sealing membrane. 14. The tank as claimed in claim 13, wherein the first and second panels are fitted with pins for fastening the primary thermal insulating barrier, these pins projecting inward from the inner surfaces of said first and second panels. 15. The tank as claimed in claim 13, wherein the pins for fastening the primary thermal insulating barrier extend in the axis of one of the metal connecting strips, and the edges of the metal plates welded to the metal connecting strips and/or to the angle piece and the edges of the angle piece welded to the metal connecting strips and/or to edges of the metal plates welded to said metal connecting strips are provided with cut-outs for the passage of the pins for fastening the primary thermal insulating barrier. 16.
