The present invention relates to a buoy used in fish farms, etc. The buoy includes a pair of outer shells (10, 10') and a pair of inner shells (20, 20') located between the outer shells (10, 10'). The pair of outer shells (10, 10') each include an outer skin (12) having a mating surface (11) that is ultrasonically or thermally welded to a corresponding outer shell and a grid reinforcing rib (14) formed in an inner space of the outer skin (12) to open toward the mating surface (11) and to be relatively shallower than the mating surface (11). The pair of inner shells (20, 20') each include an inner skin (22) having a mating surface (21) that is ultrasonically or thermally welded to the corresponding inner shell, a grid reinforcing rib (24) formed in an inner space of the inner skin (22) and opening toward the mating surface (21), and a closing surface (26) formed opposite to the mating surface (21), to which the grid reinforcing rib (14) formed in the inner space of the outer skin (12) is ultrasonically or thermally welded. Therefore, the inner shells (20, 20') are accommodated inside the outer shells (10, 10') and the inner and outer shells are joined together in an integral structure to create a plurality of compartments (C, C'). According to the present invention, the buoy can maintain buoyancy despite being partially damaged by external forces such as waves or ships, and has improved structural strength due to a double-layered structure of the inner and outer shells.

    본 발명은 양식장 등에 사용되는 부표에 관한 것으로, 1쌍의 외부 쉘(10,10')과, 상기 외부 쉘(10,10') 사이의 내측에 위치하는 1쌍의 내부 쉘(20,20')로 이루어지고, 상기 1쌍의 외부 쉘(10,10')은 대응하는 외부 쉘과 초음파 또는 열융착되는 접합면(11)을 갖는 외피(12)와, 상기 외피(12)의 내부 공간에 접합면(11) 쪽으로 개방되고 접합면(11)보다 상대적으로 얕게 형성된 격자형 보강리브(14)로 이루어지며, 상기 1쌍의 내부 쉘(20,20')은 대응하는 내부 쉘과 초음파 또는 열융착되는 접합면(21)을 갖는 내피(22)와, 상기 내피(22)의 내부 공간에 접합면(21) 쪽으로 개방된 격자형 보강리브(24) 및 상기 접합면(21)의 반대쪽에 형성되어 상기 외피(12)의 내부 공간에 형성된 격자형 보강리브(14)가 초음파 또는 열융착되는 폐쇄면(26)으로 이루어져 상기 외부 쉘(10,10') 내부에 내부 쉘(20,20')이 수용되면서 상호 일체가 되도록 접합되는 것에 의해 복수의 격실(C,C')을 갖도록 되어 있다.
