- FIG. 5 is a diagram illustrating a modified example of the third example of the connecting structure between the inner tank side plate and the tank foundation by the first anchor strap.
- FIG. 6 is a diagram illustrating a fourth example of a structure in which the inner tank side plate and the tank foundation are connected by the first anchor strap.
- FIG. 7 is a diagram illustrating a fifth example of a structure in which the inner tank side plate and the tank foundation are connected by the first anchor strap.
- FIG. 8 is a diagram illustrating a sixth example of a structure in which the inner tank side plate and the tank foundation are connected by the first anchor strap.
