<p>PURPOSE:To prevent breakings by specifying the shapes and the fixing method of said walls, the bottom corner part of an inner pool. CONSTITUTION:An outward convex curved part 7 is set to the bottom corner part of an inner pool 6, and to the curved part 7 are set loose folds 10 of approximately semi-circular section in intensified intervals toward the inner periphery direction, continuing from the side wall to the bottom. Also, folds 11 continuing vertically with suitable intervals toward the periphery direction are set to the side wall of the inner pool 6. And, the part around the border between the side wall and the curved part 7 of the inner pool 6 is anchored along the periphery with suitable interals, and also, the part near the border between the curved part 7 and the bottom is anchored 9 in the same manner. Under this structure, the bottom of the inner pool 6 ceases its movement against adiabatic material 4, and also, the peripheral thermo-distortion of the bottom corner is absorbed by folds 10 and the peripheral thermo-distortion of the side wall is absorbed by folds 11, thus achieving the desired goal.</p> |
