PURPOSE:To facilitate mounting of a corrosion-resisting plate material by pre- arranging a mounting lug piece that is used to mount the corrosion-resisting plate on the outside plating of a ship in a tile shape, on a virtual circular gap formed by the corner notches of adjacent four plate materials. CONSTITUTION:To mount a pollutionproof of plate material 3 on the outside plating 2 of a hull S under the water level, notched sections 3a are provided at their own corner of each plate material 3 and a lug piece 5 with a larger outer diameter (d) than a gap (s) that is formed by the corner of the adjacent four plate materials 3 are pre-arranged and sealed temporarily. Then based on these lug pieces 5, each plate material 3 is sealed effectively in a tile shape. As a result, joints 4 are automatically formed in good order between these adjacent four plate materials 3. Besides, each of the lug pieces 5 is hit by a hammer or the like and removed after the plate material 3 is sealed. |
