PURPOSE: A hollow multi-cell buoy is provided, which has a simple manufacturing process and prevents generation of faults in the manufacture. CONSTITUTION: A hollow multi-cell buoy includes: upper and lower bodies(100,200) which have an empty space; hollow shafts(120,220) which are respectively prepared to the center of the upper and lower bodies; a partition support which is formed in the inner sidewall of the upper and lower bodies; and a partition part(300) which is installed between the upper body and lower body and is punched in the central part. The upper and lower bodies and the partition part of the buoy are combined by the ultrasonic bonding method. The partition support uses several supporting plates. |
