Abstract
PURPOSE: To make it possible to effectively perform additional installation of block in such a way that gelid chambers are provided on the upper surface of the block, with use of volumetric expansion due to gelation of water in the gelid chambers, insertion and deaw-out of a spacer plate can be readily done.
CONSTITUTION: Ship's bottom 1 is supported through wooden sleeper materials 2, 3 and an ice making basin 8 by concrete block 9, when block is additionally installed, water is filled in gelid chambers 6 in an ice making basin, after refeigerant is flowed into refrigerant pipes 7, water in the gelid chambers is frozen. A pressured steel plate 4 is somewhat lifted by volumetric espansion due to this gelation. In this condition, insertion of a spacer plate into the interstice between the lower surface of the pressured steel plate 4 and the ice making basin 8 makes it possible to securely supported even though refrigerant in the refrigerant pipe 7 is drawn out. Also at the time of taking out the block, with the refrigerant pipe 7 flowed refrigerant in, water in the gelid chambers 6 is frozen, with use of its volumetric expansion, the pressured steel plate 4 is somewhat lifted, and the spacer plate is taken out.
