Abstract:
The disclosure relates to a corner structure which is suitable for a sealed and thermally insulating tank for storing a fluid comprising a secondary thermal insulation barrier which is retained on a carrier structure, a secondary sealing membrane, a primary thermal insulation barrier and a primary sealing membrane which is intended to be in contact with the fluid contained in the tank, the corner structure comprising: a first panel and a second panel forming a corner of the secondary thermal insulation barrier, and comprising an external face intended to move opposite the carrier structure and an internal face; a corner arrangement of the secondary sealing membrane, which arrangement is fixed to the first and second panels; a first insulating block and a second insulating block of a primary thermal insulation barrier which are fixed to the first and second panels, respectively, and which rest against the corner arrangement of the secondary sealing membrane; and a corner of a primary sealing barrier comprising a first wing and a second wing which are fixed to the first and second insulating blocks, respectively:
Abstract:
A sealed and thermally insulated tank arranged in a bearing structure (1) to contain a fluid, said tank comprising walls fixed to said bearing structure, a tank wall having a primary sealed barrier, a primary insulating barrier, a secondary sealed barrier and a secondary insulating barrier, the tank comprising a through-element arranged through the tank wall, in which tank the tank wall around the through-element comprises: secondary insulating blocks arranged on the wall of the bearing structure around the through-element and being covered by a first sealed layer forming the secondary sealed barrier, a circular plate arranged parallel to the tank wall at the same level as the first sealed layer forming the secondary sealed barrier, a second sealed layer (723a-d) fixed in a sealed manner straddling the first sealed layer and the circular plate all around the circular plate.
