For this reason, even if the membrane panel has a curved shape like the two-sided corner membrane panel M3, the spacer 6 comes into contact with both the pressing part 5f and the two-sided corner membrane panel M3 so as to make surface contact. Thereby, the fall of the sealing performance between 5 f of pressing parts and the two-surface corner membrane panel M3 can be prevented.
- the spacer 6 is interposed between the two-surface corner membrane panel M3 and the contact surface 5f3 having different surface shapes that are difficult to make surface contact, the spacer 6 is installed. You can make the most of the benefits.
- the spacer 6 is formed in an annular shape so as to surround the connection portion between the anchor 5e and the pressing component 5f of the two-sided corner membrane anchor mechanism 5.
- Such a spacer 6 is arranged so as to surround the anchor 5e when viewed from the axial direction of the anchor 5e before screwing the pressing part 5f onto the anchor 5e, and then the pressing part 5f is attached to the anchor 5e. It can be easily interposed between the pressing component 5f and the two-sided corner membrane panel M3.
- the present invention is not limited to this, and between the planar membrane panel M1 and the pressing component 3c of the planar membrane anchor mechanism 3, or between the three-surface corner membrane panel M2 and the pressing component of the three-surface corner membrane anchor mechanism 4. It is also possible to adopt a configuration including a spacer interposed between the two.
- the two-surface corner membrane anchor mechanism 5 can be adjusted in the extending direction of the two-surface corner portion 2B.
- the outer shape of the spacer 6 (the shape of the outer edge 6a) and the shape of the opening 6b are elliptical shapes that are long in the direction in which the position of the anchor 5e can be adjusted (that is, the extending direction of the two-surface corner portion 2B).
- the opening 6b is elliptical, and therefore the position of the two-surface corner membrane anchor mechanism 5 can be adjusted without changing the installation position of the spacer 6.
- the outer shape of the spacer 6 is similarly elliptical, even when the positional relationship between the spacer 6 and the pressing component 5f is changed by adjusting the position of the two-surface corner membrane anchor mechanism 5.
- the contact area between the spacer 6 and the pressing component 5f can be kept sufficiently large, and high sealing performance can be ensured.
- the membrane anchor mechanism when the membrane anchor mechanism includes a pressing component that presses the membrane from the inside of the low-temperature tank, a decrease in sealing performance between the pressing component and the membrane is prevented.
