Abstract
(EN)
Disclosed is a heat insulation structure for corner parts of a liquefied natural gas storage tank. According to the present invention, in a liquefied natural gas storage tank having sequentially stacked therein a second heat insulation wall arranged on each of the inner walls of a ship body and comprising a plurality of second heat insulation panels, a second sealing wall installed on the second heat insulation wall, a first heat insulation wall arranged on the second sealing wall and comprising a plurality of first heat insulation panels, and a first sealing wall installed on the first heat insulation wall, the liquefied natural gas storage tank comprises a corner part assembly which finishes the edges of the first sealing walls at corner parts of the storage tank, thereby completing sealing of the storage tank. The corner part assembly comprises an end cap sheet which finishes and seals the four edges of the first sealing walls installed on the respective surfaces of the storage tank, wherein, in the end cap sheet, there are formed end cap wrinkles, which finish wrinkles formed in the first sealing walls and have an end cap shape, and long wrinkles extending in a direction perpendicular to the direction in which the end cap wrinkles extend.

L'invention concerne une structure d'isolation thermique pour des parties d'angle d'un réservoir de stockage de gaz naturel liquéfié. Selon la présente invention, dans un réservoir de stockage de gaz naturel liquéfié dans lequel sont empilées séquentiellement une seconde paroi d'isolation thermique agencée sur chacune des parois internes d'un corps de navire et comprenant une pluralité de seconds panneaux d'isolation thermique, une seconde paroi d'étanchéité installée sur la seconde paroi d'isolation thermique, une première paroi d'isolation thermique disposée sur la seconde paroi d'étanchéité et comprenant une pluralité de premiers panneaux d'isolation thermique, et une première paroi d'étanchéité installée sur la première paroi d'isolation thermique, le réservoir de stockage de gaz naturel liquéfié comprend un ensemble partie d'angle qui termine les bords des premières parois d'étanchéité au niveau de parties d'angle du réservoir de stockage, réalisant ainsi l'étanchéité du réservoir de stockage. L'ensemble partie d'angle comprend une feuille de bouchon d'extrémité qui termine et scelle les quatre bords des premières parois d'étanchéité installées sur les surfaces respectives du réservoir de stockage. Dans la feuille de bouchon d'extrémité sont formés des plis de bouchon d'extrémité, qui terminent les plis formés dans les premières parois d'étanchéité et ont une forme de bouchon d'extrémité, et de longs plis s'étendant dans une direction perpendiculaire à la direction dans laquelle s'étendent les plis de bouchon d'extrémité.
