And 5 were permanently attached (see the two-dot chain line portion), the side plates 1 and 2 were temporarily attached, and the main welding was performed. According to this method, a problem occurs in that the lower surface of the tank A is deformed as shown in FIG. 3 due to welding distortion, and it is necessary to tighten the bolt after adjusting the shim when mounting the tank A. For this reason, there is a possibility that the mounting workability is deteriorated, the bolt is loosened, and the fatigue life is shortened due to stress strain generated at the time of mounting.

Reference numeral 4 denotes a plate attached to the bottom of the side plate 2. The plate 4 has an inverted hat shape in vertical section as shown in FIG. 6B, and is attached by straddling welding from the bottom 2a to both sides 2b of the side plate 2 as shown in FIG. With this configuration, the rigidity of the plate 4 is further improved, the welding distortion generated when the side plates 1 and 2 are fully welded can be further reduced, and the flatness of the plate 4 can be improved. . As described above, the mounting workability can be improved, and at the same time, loosening of the bolt and reduction in fatigue life can be prevented.

することができる。[Effect] In an oil tank formed by welding side plates 1 and 2 formed in a U-shape, a plate 4 attached to the bottom 2a of one of the side plates 2 has an inverted hat shape in cross section, and the bottom 2a of the side plate 2 And the lower part of the side part 2b. With this configuration, the rigidity of the plate at the bottom of the side plate is further improved, and welding distortion generated when the two side plates are fully welded can be reduced. For this reason, the flatness of the plate is further improved, so that not only the mounting workability is improved compared to the conventional one but also the loosening of the bolt and the shortening of the service life due to the distortion can be prevented.
