Abstract

PURPOSE:To protect an inner hollow body by an outer hollow body and the space between both the inner and outer hollow bodies, and semipermanently ensure the function as a float even when a part of a hollow float is broken by arranging the inner hollow body in the inner part of the outer hollow body with a space to constitute the hollow float. CONSTITUTION:A hollow float is applied to a floating workshop on water. The hollow float has an inner hollow body 13 arranged in the inner part of an outer hollow body 11 with a space. The outer hollow body 11 has a recessed reinforcing part 12, for example, on the circumferential side wall, and is formed into a cube from plastics. On the other hand, the inner hollow body 13 has a recessed reinforcing part 14 on the circumferential side wall and a square projection 15 for space holding on the central part of both upper and lower walls, and is formed into a cube from plastics. Thus, the inner hollow body 13 is protected by the outer hollow body 11 and the space between both the inner and outer hollow bodies 13, 11. Thus, even when a part of the hollow float is broken, the function as the float can be semipermanently ensured.

（浮力体）の改良に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a hollow float (buoyant body) used for a floating work place on the water, a floating platform, a floating bridge and the like.

【０００２】[0002]

【従来の技術】周知のように従来の中空フロートは一重
の中空構造からなっている。As is well known, a conventional hollow float has a single hollow structure.

【発明が解決しようとする課題】従って従来の中空フロ

【０００４】この発明は上記のような問題に鑑み、中空

機能が失われないようにすることを目的としている。In view of the above problems, an object of the present invention is to prevent the function of the float from being substantially lost even if a part of the hollow float is damaged.

的に維持される。In the hollow float of the present invention, the outer hollow body and the space between the outer hollow body and the inner hollow body function as a guard for the inner hollow body due to the hollow double structure. Therefore, in particular, if the wall thickness of the outer and inner hollow bodies and the distance between the outer and inner hollow bodies are appropriately selected and a reinforcing portion is provided if necessary, the outer hollow body will not be substantially damaged by the impact. It does not extend to the hollow body, and the function as a float is maintained almost semipermanently.
