Cryogenic tank
A cryogenic tank includes a heat insulating material layer which is disposed between a concrete wall and a membrane and includes a secondary barrier layer in an inner portion of the heating insulating material, and a membrane anchor mechanism which penetrates the secondary barrier layer, is fixed to the concrete wall, and presses the membrane. The membrane anchor mechanism includes a seal portion which covers a through portion penetrating the secondary barrier layer.
1. A cryogenic tank comprising:
a heat insulating material layer which is disposed between a concrete wall and a membrane and includes a secondary barrier layer in an inner portion of the heating insulating material; and
a membrane anchor mechanism which penetrates the secondary barrier layer, is fixed to the concrete wall, and presses the membrane,
wherein the membrane anchor mechanism includes a seal portion which covers a through portion penetrating the secondary barrier layer, and
wherein the seal portion is an adhesive layer including a glass cloth.
2. A cryogenic tank according to claim 1 ,
wherein the membrane anchor mechanism includes a leg portion which penetrates the secondary barrier layer, and
wherein the seal portion is provided to cover the leg portion when viewed in a direction in which the leg portion penetrates the secondary barrier layer.
