(C) shows a single-body cylindrical liquefied gas tank 2 that is independently mounted inside the liquefied gas carrier 1, and the liquefied gas tank 2 has a cylindrical tank body 3 whose both ends are closed by end plates 4. In addition, a required portion of the inner side surface of the tank body 3 is reinforced by a support ring 5, and when it is supported on a tank support base 6 installed in a ship, a circle is formed on the tank support base 6. The tank block 3 of the portion reinforced by the support ring 5 is placed on the support block 7 formed in an arc shape so as to be positioned horizontally.

ているのが一般的である。A supporting block 7 for directly supporting the tank shell 3 of the liquefied gas tank 2 absorbs elastic deformation of the hull and the tank shell 3 itself and is a material suitable for keeping cold, such as a plywood block made of wood. It is common to use materials with a low rate.

いう問題がある。However, in the support block 7, the end portion 7a is caused by the elastic deformation of the tank body 3 itself as shown in the portion a of the reaction force distribution diagram in FIG. 3C. Since a remarkable reaction force concentration is observed, the width of the support block 7 is increased or the support block 7 is made of a material having high strength (for example, impregnated plywood) so as to have sufficient strength for the reaction force concentration. It was necessary to take measures such as adopting
Incidentally, when the width is increased only at the end 7a of the support block 7 or when the impregnated plywood having high strength is used, the spring constant is increased only at the end 7a, so that the reaction force is rather exerted on the end 7a. There is a problem that it causes the result of concentration.

ヤング率の小さい材料にて製作してなる構成とする。FIG. 1 shows an embodiment of the present invention. An example of application to a single-body cylindrical liquefied gas tank 2 having the same structure as shown in (a), (b) and (c) of FIG. Show. That is, a support block 8 for supporting the liquefied gas tank 2 having a cylindrical tank body 3 and arranged laterally from below is provided with a required length corresponding to the outer peripheral surface of the lower half of the tank body 3. Is formed in an arc shape and the supporting block 8
The thickness d 1 of both end portions 8a is thicker than the thickness d 0 of the other portion 8b, and the whole is made of a material having a small Young's modulus such as wood such as a plywood block.

示すように緩和され、反力分布が一様になる。In the case of the support block 8 configured as described above, the thickness of the end portion 8a is made thicker than the thickness of the other portion 8b. However, if there is a slight difference in this thickness, the end portion 8a will be localized. The apparent spring constant can be lowered. Therefore, as shown in FIG. 1, when the liquefied gas tank 2 is supported on the tank support base 6 which is a part of the hull structure by using the support block 8 in which the thickness of the end portion 8a is thicker than the thickness of the other portion 8b. Since the amount of deformation of the end portion 8a with respect to the unit load becomes large, the reaction force concentration that originally occurs at the end portion 8a is shown in FIG.
(C) is relaxed from the state of part a, as shown in part a'in FIG. 1, and the reaction force distribution becomes uniform.

可能となる。As described above, since the concentration of the reaction force when supporting the liquefied gas tank 2 can be relaxed and made uniform, the total amount of the support block 8 can be reduced as compared with the conventional support block 7. Or it can be made of a material of relatively low strength. Further, with respect to the stress generated in the support ring 5 (see (b) of FIG. 3) attached to the inner side surface portion of the tank body 3, the concentrated stress at the corresponding position is similarly mitigated, so that the support ring 5 has The size can be reduced. Further, also in the tank support base 6 on the hull side, the stress concentration is similarly relaxed, so that the size can be reduced.
