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.

Description

Detailed Description of the Invention

[0001]

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]

As is well known, a conventional hollow float has a single hollow structure.

[0003]

Therefore, the conventional hollow float has a problem that even if a part of the hollow float is damaged by an impact from the outside, it is flooded to the inside and all or most of the function as the float is lost.

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.

[0005]

According to the present invention, in order to achieve the above object, a hollow float has a hollow double structure in which an inner hollow body is installed inside an outer hollow body with a space therebetween. .

[0006]

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.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show the outline of the structure of an embodiment of the hollow float according to the present invention. A cubic inner hollow body 13 made of plastic, which is one size smaller than the outer hollow body 11, and has a concave reinforcing portion 14 and an angular protrusion 15 for maintaining a gap in the central portion of the upper wall and the lower wall, It has a concentric structure.

The hollow float of this illustrated example has an inner hollow body 1
3 is protected by the outer hollow body 11 and the space between the outer hollow body 11 and the inner hollow body 13, and there is almost no risk of being affected by breakage of the outer hollow body 11.

The present invention can be implemented in various forms other than the above, and is not limited to the illustrated example.

[0010]

As is apparent from the above description, according to the hollow float of the present invention, it can be used semipermanently in spite of the relatively simple structure of the double hollow structure. A useful effect is produced.
