The float structure according to the embodiment of the present invention, the floating structure on the water surface using the float structure, and the mooring berth using the same will be described in detail with reference to Examples 1 to 3.

First, the structure of the float structure 1 according to the first embodiment of the present invention will be described in detail with reference to FIG.
FIG. 1 is a perspective view showing a part of the cover of the float structure according to the first embodiment of the present invention.
As shown in FIG. 1, the float structure 1 according to the first embodiment is a first fixture that binds a plurality of floating bodies 2 made of resin foam and the plurality of floating bodies 2 so as to form a single floating body group 3. 4 and a cover 5 that covers the entire surface of the floating body group 3 of the mass bound by the first fixture 4 are provided.

The floating body 2 in the float structure 1 according to the first embodiment is, for example, a resin foam formed into a thick plate and cut to a desired length. Further, the floating body group 3 in the float structure 1 is a mass formed by assembling a desired number of such floating bodies 2 without gaps.
Generally, when the floating body 2 is used as a float for a cage or a raft while being exposed, or as a float for a mooring berth, the floating body 2 is exposed to ultraviolet rays or heat for a long period of time outdoors (mainly on the water surface such as at sea or lake). Will be. Therefore, when the floating body 2 is used as a float while being exposed, the floating body 2 itself needs to have sufficient weather resistance.
On the other hand, in the float structure 1 according to the first embodiment, the entire surface of the floating body 2 is always covered with the cover 5. Therefore, the floating body 2 constituting the float structure 1 according to the first embodiment does not have to have sufficient weather resistance by itself.
That is, the floating body 2 constituting the float structure 1 according to the first embodiment has strength to the extent that it is not easily deformed or damaged when it is bound by the first fixture 4, and it is easy to come into contact with fresh water or seawater. Any resin foam that does not deteriorate or decompose can be used.
More specifically, as the material of the floating body 2, for example, polystyrene foam, urethane foam, or the like can be used.
Further, for the reason as described above, as the floating body 2 constituting the float structure 1 according to the first embodiment, for example, a plate-shaped resin foam scrap used as a heat insulating material for heat insulation or cold insulation may be used. it can.
In this case, the scraps of the heat insulating material for heat insulation or cold insulation, which have been forced to be discarded in the past, can be effectively used as a part of the float structure 1 according to the first embodiment.

Further, the floating body group 3 in the float structure 1 according to the first embodiment can be easily formed only by bundling a plurality of floating bodies 2 and binding them with the first fixture 4. Further, in such a floating body group, the floating bodies 2 are not joined to each other by an adhesive or the like. Therefore, in the floating body group 3 according to the first embodiment, the individual floating bodies 2 can be easily separated by removing the first fixture 4.
In addition, in the float structure 1 according to the first embodiment, the first fixture 4 is not joined to the floating body group 3 by an adhesive or the like. Therefore, it is easy to separate the first fixture 4 from the floating body group 3.
Therefore, when the floating body group 3 is used as the float structure 1 according to the first embodiment, the first fixture 4 can be easily separated from the floating body group 3 when the float structure 1 is discarded, and the floating body is also used. The individual floating bodies 2 can be separated from the group 3 and separated into individual pieces.
In this case, the work of separating each part constituting the float structure 1 according to the first embodiment becomes easy. Therefore, according to the float structure 1 according to the first embodiment, the environmental load at the time of disposal can be reduced.

Further, the first fixture 4 constituting the float structure 1 according to the first embodiment is also used in a protected state in the cover 5 like the above-mentioned floating body 2. Therefore, the first fixture 4 is not easily cut when the floating body 2 is bundled and bound, or when an external force acts on the first fixture 4 while the floating body 2 is bound, and the first fixture 4 is also fresh water. Alternatively, any material may be used as long as it is made of a material that does not easily decompose or deteriorate due to contact with seawater. Further, in the float structure 1 according to the first embodiment, as a specific form of the first fixture 4, the first fixture 4 is used. String-shaped, band-shaped, or strip-shaped ones can be used.
More specifically, as the material of the first fixture 4, for example, a polypropylene band (PP band), a rope, an adhesive tape, a shrink film, or the like can be used. In particular, a polypropylene band (PP band) is most suitable as the first fixture 4.

In the float structure 1 according to the first embodiment, the floating body group 3 may be bound and fixed using only the first fixture 4, or the end portion of the first fixture 4 may be fixed. The floating body group 3 may be tied up separately by using a fixing tool (not shown) for holding.
In particular, in the latter case, the durability of the fixing tool 4 is such that the fixing state by the first fixing tool 4 is not unintentionally released when the floating body group 3 is used. It is necessary to select a material that is equal to or better than.

On the other hand, in the float structure 1 according to the first embodiment, the cover 5 is provided to cover the above-mentioned floating body 2 and the first fixture 4 to protect them from ultraviolet rays and heat for a long period of time. Therefore, the cover 5 in the float structure 1 according to the first embodiment needs to have sufficient weather resistance and strength, unlike the floating body 2 and the first fixture 4.
Therefore, as the material of the cover 5 constituting the float structure 1 according to the first embodiment, for example, a polyester canvas, a polyethylene UV sheet, a vinyl chloride tarpaulin sheet, or the like is suitable. Further, in order for the cover 5 according to the first embodiment to exhibit sufficient strength, it is desirable that the cover 5 has a sufficient thickness.
The thicker the cover 5, the higher the strength, but the weight of the cover itself causes the buoyancy of the floating body 2 to decrease, or the flexibility of the cover 5 decreases to facilitate the work of wrapping the floating body group 3. Problems such as being unable to do so occur. Therefore, it is desirable that the thickness of the cover 5 is thinner as long as the strength and flexibility of the cover 5 are not impaired.

Further, in the float structure 1 according to the first embodiment, the cover 5 can prevent the fragments from being scattered to the surrounding water environment should the floating body 2 be damaged in the cover 5.
Therefore, according to the float structure 1 according to the first embodiment, it is possible to provide a float structure in which the surrounding water environment is not contaminated by the fragments of the floating body 2 when used.
Further, in the float structure 1 according to the first embodiment, the cover 5 is not joined to the surface of the floating body group 3 by an adhesive or the like. Therefore, in the float structure 1 according to the first embodiment, the work of attaching / detaching the cover 5 to / from the floating body group 3 can be performed extremely easily.
Therefore, according to the float structure 1 according to the first embodiment, when the cover 5 is damaged due to aged deterioration or some accident, the float structure 1 can be continued to be used as it is by simply replacing the cover 5.
Further, in the float structure 1 according to the first embodiment, the cover 5 can be easily separated from the floating body group 3 at the time of disposal. Therefore, each part constituting the float structure 1 can be easily separated. Therefore, according to the float structure 1 according to the first embodiment, the environmental load at the time of disposal can be reduced.

Further, in the float structure 1 according to the first embodiment, as a means for fixing the cover 5 on the surface of the floating body group 3 bound by the first fixture 4, for example, as shown in FIG. 1, a string-shaped second second Fixtures 6 may be used (optional component). In this case, the cover 5 can be fixed on the surface of the floating body group 3 without using an adhesive or the like.
Further, in this case, the cover 5 can be fixed on the surface of the floating body group 3 without joining. This means that the cover 5 can be easily attached to and detached from the floating body group 3 by using the second fixture 6 as the fixing means of the cover 5.
Therefore, in the float structure 1 according to the first embodiment, when the cover 5 is fixed by the first fixture 4, the cover 5 is replaced as necessary, or the cover 5 is covered from the floating body group 3 when the float structure 1 is discarded. It becomes easy to separate 5.
Therefore, when the cover 5 is fixed by using the first fixture 4 in the float structure 1 according to the first embodiment, it is possible to provide a float structure that can be easily repaired or disposed of.

As a specific form of the second fixture 6 in the float structure 1 according to the first embodiment, a string-shaped, band-shaped, or chain-shaped one can be used.
Further, in the float structure 1 according to the first embodiment, by using the second fixture 6 as the fixing structure of the cover 5, the second fixture 6 bound on the cover 5 is attached to the float structure 1. It can be used as a locking tool when fixing to the target frame or the like.
In this case, when fixing the float structure 1 to the frame or the like to which the float structure 1 is attached, a through hole is formed in the float structure 1 itself, or a locking tool is attached to the float structure 1 separately from the second fixing tool 6. There is no need to provide it.
Therefore, by using the string-shaped, band-shaped, or chain-shaped second fixing tool 6 as the fixing structure of the cover 5, the fixing structure of the float structure 1 to the frame body to be attached can be simplified.

Next, a method for manufacturing the float structure 1 according to the first embodiment will be described with reference to FIGS. 2 to 4.
FIG. 2A is a perspective view of a floating body in the float structure according to the first embodiment of the present invention, and FIG. 2B is a perspective view showing a state in which the floating bodies are assembled into a massive floating body group. The same parts as those shown in FIG. 1 are designated by the same reference numerals, and the description of their configurations will be omitted.
The first step in manufacturing the float structure 1 according to the first embodiment is a floating body preparation step (step S01) in which a desired number of floating bodies 2 of a desired size are prepared as shown in FIG. 2A.
Then, the next floating body assembling step (step S02) is a step of assembling the plurality of floating bodies 2 procured in step S01 without gaps to form a massive floating body group 3. Further, as described above, in the float structure 1 according to the first embodiment, in principle, the individual floating bodies 2 are not joined to each other by an adhesive or the like.
However, when a large number of floating bodies 2 are appropriately combined to form a floating body group 3 having a large size or a special shape, it may be necessary to temporarily fix the floating bodies 2 so as not to cause misalignment with each other. .. In such a case, the floating bodies 2 may be joined to each other by using an adhesive or the like having an adhesive force capable of easily separating the floating body group 3 into individual floating bodies 2.
Therefore, in the present invention, the floating bodies 2 are not positively bonded to each other, but the floating bodies 2 are easily separated from each other by an adhesive or the like in order to temporarily maintain the outer shape of the floating body group 3 at the time of manufacturing the floating bodies 2. The case of stopping is also included in the technical scope.

Here, a modified example of the float structure 1 of the first embodiment will be described with reference to FIG.
