(Manufacture of floating multipurpose float body 100)
Next, the manufacturing process of the floating multipurpose float body 100 will be described with reference to FIG. An operator who manufactures the floating multipurpose float body 100 first manufactures the small float body 101 as a first step (see FIG. 1). Specifically, the operator prepares a skin 103 formed in a bag shape in advance, and then injects a urethane resin raw material, which is a raw material of the hard urethane foam 102, into the skin 103 to form the small float body 101. Mold. In this case, the operator injects a liquid urethane resin material into the outer skin 103 from one of the two inlets 104 in the outer skin 103 using a urethane injection device (not shown).

  The liquid urethane resin raw material injected into the outer skin 103 is charged while spreading the outer skin 103 from the inner side, and immediately begins to cure. As a result, the urethane resin raw material injected into the outer skin 103 becomes a hard urethane foam 102 which is foamed and hardened to a size and shape corresponding to the size and shape of the inner region of the outer skin 103, and is a small float body. 101 is configured.

  In this case, the four side surfaces of the outer skin 103 swell outward in an arc shape by the urethane resin raw material introduced into the outer skin 103 to form the curved side portion 106. On the other hand, the upper surface and the lower surface of the small float body 101 are formed in a flat shape without being inflated into a spherical shape by a resin or glass thread provided in the outer skin 103.

  Next, the operator closes the inlet 104 with a sheet material after the urethane resin raw material in the outer skin 103 is cured. Production of the small float bodies 101 in this first step is carried out by the number of small float bodies 101 necessary for constructing the floating multipurpose float body 100 (five in this embodiment).

  In addition, this 1st process can be performed also in the outdoors which uses the water multi-purpose float body 100 besides the factory with a urethane injection apparatus. Specifically, the operator can prepare the urethane resin raw material in a container such as a bucket or a bottle, and can inject it into the outer skin 103 directly from the inlet 104 in the outer skin 103 or via a funnel. . That is, the floating multipurpose float body 100 according to the present invention can be completed on-site when the floating multipurpose float body 100 is used.

  Next, the worker connects the small float bodies 101 to each other as the second step. Specifically, the operator prepares at least two (five in the present embodiment) small float bodies 101 and arranges them in a direction in which they are connected to each other. In this case, the worker arranges the small float bodies 101 in a state where the curved side portions 106 between the two small float bodies 101 connected to each other face each other.

  As a result, as shown in FIG. 3, concave gaps 107 are respectively formed on both sides of the two curved side portions 106 that face each other. In this case, the operator can more firmly connect the two small float bodies 101 by applying an adhesive to the butted portions of the curved side portions 106 butted against each other.

  Next, the operator places the urethane resin raw material in one of the two concave gaps 107 formed on both sides of the curved side portion 106 butting each other, specifically, in the concave gap 107 on the side opening upward. Pour. As a result, the liquid urethane resin raw material injected into the curved side portion 106 immediately starts to cure. In this case, the worker has such an amount that the adhesive portion 108 made of the hard urethane foam solidified in the concave gap 107 reaches the surface of the two small float bodies 101 arranged adjacent to each other through the concave gap 107. Pour urethane resin raw material.

  Thereby, in the concave gap 107, an adhesive portion made of a hard urethane foam that is foamed and solidified to a level substantially flush with the surfaces of the two small float bodies 101 arranged adjacent to each other via the concave gap 107. 108 is formed. Next, the operator attaches the connecting portion cover 109 to the exposed surface of the bonded portion 108 formed by solidification using an adhesive (not shown). In this case, the operator may attach the connecting portion cover 109 only to the surface of the adhesive portion 108 exposed between the two small float bodies 101 arranged adjacent to each other, but between the two small float bodies 101. The two small float bodies 101 can be more firmly connected by sticking the connecting portion cover 109 in a state of being installed.

  The adhesive portion 108 and the connecting portion cover 109 are formed in the one concave gap 107 in the same manner with respect to the four concave gaps 107 formed between the five small float bodies 101 in this embodiment.

  Next, the operator also applies the adhesive portion 108 and the connecting portion cover 109 to the other concave gap 107 of the two concave gaps 107 formed on both sides of the curved side portion 106 that abut each other. Perform forming operations. In this case, the operator turns the top and bottom of the small float body 101 to be connected upside down so that the other concave gap 107 faces upward, and then pours the urethane resin material.

  Regarding the formation of the adhesive portion 108 and the connecting portion cover 109 in the other concave gap 107, the four concave gaps 107 formed between the five small float bodies 101 in the present embodiment are the same as described above. Repeat for each. Thereby, the water multipurpose float body 100 in which the five small float bodies 101 are connected is integrally completed.
