A membrane anchor mechanism which fixes a membrane provided on an inner wall surface side of a concrete wall via a heating insulating material to the concrete wall in a cryogenic tank, comprising:
- a rod-shaped leg portion which is erected on the concrete wall;
- an anchor which is supported by the leg portion, wherein the anchor is supported by the leg portion at a position such that the anchor is separated from the concrete wall, and wherein the anchor is inserted into a through-hole passing through the heat insulating material and the membrane, and wherein the anchor includes a tip which extends outside of the through-hole such that the tip is exposed to an inside of the cryogenic tank;
- and
- a pressing part which is fixed to the tip of the anchor at a position of the tip exposed to inside of the cryogenic tank, and wherein the pressing part presses the membrane.
