The support 110 is provided on the bottom surface of the hull 20 to support the storage tank 10. The support 110 is provided between the foundation 30 contacting the bottom surface of the hull 20 and the storage tank 10, and supports the load of the storage tank 10 and transmits the load of the storage tank 10 to the bottom surface of the hull 20.
The supporting portion 110 may be made of wood, but the material of the supporting portion 110 is not limited to wood. The support portion 110 may be formed in a rectangular parallelepiped shape, but may also be formed in a cylindrical shape.
The heat insulating material 120 is closely attached to both side surfaces of the support part 110, and the heat insulating material 120 may be formed of a material such as urethane foam. The support portion 110 is provided with a groove 111 at a predetermined height, and the end of the plate portion 140 is fastened to the groove 111.
The groove 111 may be provided at a predetermined height of the support 110, and may be provided at a middle portion of the height of the support 110, but the groove 111 may be formed at a portion other than the middle portion in order to prevent leakage of the liquefied natural gas.
When the groove 111 is positioned at the upper portion of the support 110, a moving path of the leaked natural liquefied gas can be shortened.

And (4) shaping.
In this case, in order to insert and fix the jig 180, the groove portion 111 is cut at a preset length and a preset height perpendicular to the height direction of the support portion 110.
Referring to fig. 2, the plate part 140 extends a predetermined length along the longitudinal direction of the groove part 111, and is provided to prevent leakage and further progress of the lng.
One end of the plate portion 140 is inserted into the groove portion 111 and is fastened to the inner surface of the groove portion 111 by a fastening means 143. The plate portion 140 may be formed in a straight line or T-shape in cross section, but may be formed in a cross section as shown in FIG. 2
Figure BDA0002127347810000041
And (4) shape. However, the section of the plate portion 140 is not limited to the "T" shape or
Figure BDA0002127347810000042

Since the plate portion 140 has
Figure BDA0002127347810000044
The shape of the plate portion 140 increases the coupling rigidity when the plate portion is fastened to the groove portion 111, and the plate portion is stably fixed to the inner surface of the groove portion 111, and since the other end portion maintains a straight shape, the thickness thereof can be reduced, and leakage of the liquefied natural gas and further leakage thereof can be prevented.
The groove 111 is filled with an adhesive 145. That is, a portion other than the plate portion 140 in the inside of the groove portion 111 may be filled with the adhesive portion 145. The adhesive portion 145 may be formed of a low-temperature adhesive or the like.
The thermal insulator 130 is disposed between the side surface of the support part 110 and the thermal insulator 120, and serves as a passage for transferring ultra-low-temperature goods (liquefied natural gas) loaded in the storage tank 10 when the ultra-low-temperature goods leak.
The flame-proof member 130 is formed to be porous, and one end of the flame-proof member 130 is connected to the plate 141 of the plate portion 140.
An auxiliary plate 150 is provided below the heat insulator 120, and the auxiliary plate 150 is fastened to a predetermined position by a fastener 151.
The auxiliary plate 150 stably supports the lower portion of the heat insulator 120 and prevents leakage of the lng leaking along another path in advance.
The auxiliary plate 150 may be formed longer than the plate part 140.
In the past, some of the heat insulators are formed to correspond to the thickness of the groove portions, and therefore, additional operations are required to seal the side surfaces of the support portions and the heat insulators and the flame insulators.
According to the present invention, since the plate portion is provided at the groove portion, the installation operation can be easily performed, and it is not necessary to perform an additional operation for sealing the gap between the support portion, the heat insulator, and the flame insulator, and the leakage of the liquefied natural gas can be stably prevented.
