Abstract

PURPOSE:To prevent slippage of an inner shell of a double shell type cold tank, by cancelling the horizontal force acted to the inner shell at the time of an earthquake by the reaction force of restriction plates which are interposed between the inner shell and a low-temperature insulating material disposed at the bottom of the tank in the manner that it is not continuous in the circumferential direction of the tank. CONSTITUTION:The horizontal force acted to an inner shell 14 of a double-shell type cold tank is supported by the frictional force acted between the bottom plate of the inner shell 14 and a low-temperature insulating material 16 disposed at the bottom of the tank. At the same time, the horizontal force is transmitted to the low-temperature are welded at one ends thereof the inner shell 14 and buried in the low-temperature insulating material 16 at the other ends thereof. Here, since the material 16 is extended to the side plate of an outer tank 11, the horizontal force transmitted to the material 16 is transmitted further to the side plate of the outer shell 11. The horizontal force thus transmitted to the side wall of the outer shell 11 is supported by the frictional force acted between the bottom plate of the outer shell l1 and a foundation 13, so that the horizontal movement of the inner shell 14 is restricted by the restriction plates 17.
