The present invention relates to a buoyancy assembly, which comprises: an upper casing which has a cylindrical-shaped body, and is formed in a shape whose cross-sectional area becomes narrower toward the upper side, while being provided with a hollow inside; a lower casing which, in order to correspond to the upper casing, has a cylindrical-shaped body, and is formed in a shape whose cross-sectional area becomes narrower toward the lower side, while being provided with a hollow inside; an upper flange which is formed while being horizontally extended from the edge of the lower end of the upper casing; a lower flange which is formed while being horizontally extended from the edge of the upper end of the lower casing; a fastening unit which is coupled while penetrating the upper flange and the lower flange; an upper coupling unit which is formed at the upper end of the upper casing; and a lower coupling unit which is formed at the lower end of the lower casing. Here, polyurethane foam is inserted into the upper casing and the lower casing. Therefore, durability can be increased.

    본 발명은 부력 조립체에 관한 것으로, 그 구성은, 원기둥형상의 몸체에 상방으로 갈수록 횡단면적이 좁아지는 형상으로 형성되고 내부가 중공되는 상부케이싱과, 상기 상부케이싱에 대응되도록, 원기등형상이 몸체에 하방으로 갈수록 횡단면적이 좁아지는 형상으로 형성되고 내부가 중공되는 하부케이싱과, 상기 상부케이싱의 하단의 가장자리에 수평으로 연장되어 형성되는 상부플랜지와, 상기 하부케이싱의 상단의 가장자리에 수평으로 연장되어 형성되는 하부플랜지와, 상기 상부플랜지와 상기 하부플랜지를 관통하여 결합되는 체결부와, 상기 상부케이싱의 상단에 형성되는 상부결합부와, 상기 하부케이싱의 하단에 형성되는 하부결합부를 포함하고, 상기 상부케이싱과 상기 하부케이싱의 내부에는 폴리우레탄폼이 삽입되는 것을 특징으로 한다.
