PURPOSE:To prevent damage due to the contact of a chock with a bracket when an upper deck is mounted, by previously mounting then bracket, which forms a required clearance for a cushion block further provides an upper part guide frame in the upper part position from the cushion block, to a bottom surface of the upper deck. CONSTITUTION:A tank 2 is completed, and after it is mounted into a ship, an upper deck 3 is mounted. Here a bracket 5 is left as fixedly provided in a bottom surface of the upper deck 3, further an L-shaped upper guide frame 9 is left as secured to an adapted surface of the bracket 5. Further the upper guide frame 9 is set to a height position where it is not brought into contact with a cushion block 6 in the side of a chock 4, still further the bracket 5 is designed in the arrangement such that a required clearance C is formed in one side between the bracket and the cushion block 6. Accordingly, when the upper deck 3 is mounted, possibility of the bracket 5 coming into contact with the cushion block 6 is eliminated, and the both bracket and cushion block are prevented from damage.
