Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating structure for floating on water such as an ocean or lake to obtain a living space on the ocean or lake.

[0002]

2. Description of the Related Art Today, the conservation of the global environment is regarded as an international issue, and a large-scale survey on water quality and weather is being demanded. It is desirable to perform a detailed inspection for this environmental survey over a long period of time, and for this purpose, a large living space that floats in the ocean or lakes is required instead of the survey ship whose maintenance cost is extremely high. As a floating structure of this type, there is a structure in which a skeleton including a roof is constructed on an upper side of a floating ring-shaped floating body, as disclosed in Japanese Patent Application Laid-Open No. 4-357209 (E02D 17/00). .

[0003]

However, in such a conventional floating structure on the water, since the entire buoyancy is obtained by the floating body from the viewpoint of the ship, the skeleton constructed on the upper side of the floating body. In order to support the above load, the floating body must be remarkably increased in size, and its structural strength must be significantly increased. Therefore, there is a problem that the structure of the floating structure becomes complicated, it takes a long time to construct, and the floating structure becomes extremely expensive.

In view of the conventional problems, it is therefore an object of the present invention to provide a floating structure on the water which can easily and inexpensively obtain a large living space.

[0005]

In order to achieve such an object, the present invention provides a ring-shaped annular base body provided with buoyancy adjusting means, and an airtight structure attached to the annular base body so as to cover the central space portion thereof. The roof membrane is submerged to raise the internal pressure, and the roof membrane is expanded and supported in a dome shape to be constructed on water.

Further, it is desirable that a plurality of cables are radially and laterally attached to the roof membrane, if necessary, and the ends of the respective cables are fixed to the annular base body.

Further, it is desirable to attach a radial structure to the inner circumference of the annular base body.

Furthermore, the inside of at least one of the annular base body and the radial structure can be hollowed, and this hollow portion can be used as a living space.

Further, the annular base body is provided with an access route defined by an internal pressure adjusting zone, and the access is made through this access route.

Furthermore, a fish reef to be submerged may be provided below the annular base body.

Further, a capsule that is submerged in water is provided below the annular base body, and the capsule is connected to the annular base body or the radial structure through a passage.

Further, it is desirable that the radial structure is provided with an annular transportation path concentric with the annular substrate.

Furthermore, the annular base is constructed as a combination of a plurality of small-diameter circular arcs so as to form a pleat-shaped ring as a whole, and a roof membrane attached to the annular base is radially provided corresponding to the connecting portion of the small-diameter circular arcs. It is desirable to form the concave grooves and to swell the roof membrane in a petal shape between the concave grooves.

[0014]

In the floating structure above water according to the present invention having the above-mentioned structure, the annular base body is present in an airtight state between the central space of the annular base body and the roof membrane by sinking the annular base body by the buoyancy adjusting means. By pressurizing air to raise the internal pressure, the roof membrane is inflated and supported, and is floated on water by the air buoyancy of the roof membrane. Therefore, it is not necessary to provide the annular substrate itself with buoyancy for supporting the entire floating structure, and the strength of the annular substrate can be significantly reduced. Therefore, the structure of the floating structure itself can be remarkably simplified in combination with the use of the roof membrane. By the way, since the pressure expansion of the roof membrane is obtained by the subsidence of the annular substrate, it is not necessary to provide a special means for pressurizing the roof membrane, and the structure can be simplified also from this point.

Further, a plurality of cables are radially attached to the roof membrane, and if necessary, are laterally attached, and the ends of the radial cables are fixed to the annular base body so that the tension acting on the roof membrane is supported by the cables. Therefore, even if the roof membrane is remarkably enlarged, it is not necessary to thicken the roof membrane to obtain strength, which in turn reduces the weight of the roof membrane and simplifies the laying work. Can be planned.

Further, by mounting the radial structure on the inner circumference of the annular base body, even when a large load in the radial direction acts on the annular base body when the roof membrane is expanded, this load is applied to the radial base structure. Since it can be supported by the body, the strength of the annular base can be significantly increased, and the structural simplification and weight saving of the annular base can be achieved.

Furthermore, by making the inside of the annular base body hollow and making this hollow portion a living space, the annular base body can be effectively utilized as a living space.

Further, by hollowing the inside of the radial structure and making this hollow portion a living space, the radial structure can be made lighter and can be effectively used for a living space.

Further, by providing an access route defined by the internal pressure adjusting zone in the annular base body and entering and exiting through the access route, it is possible to easily enter and exit the inside of the annular base body from the outside. .

Furthermore, by providing a fish reef to be submerged below the annular substrate, it is possible to easily observe the aquatic ecosystem and culture the fish.

Further, a capsule that is submerged in water is provided below the annular base body, and the capsule is communicated with the annular base body or the radial structure through a passage to facilitate observation in water through the capsule. In addition, it is possible to easily enter and exit the capsule through the passage without going out into the water.

Further, by providing the radial structure with an annular transportation path that is concentric with the annular base body, it is possible to facilitate the comings and goings to and from each living space.

Furthermore, the annular base body is constructed as a combined body of a plurality of small-diameter circular arcs so as to form a pleat-shaped ring as a whole, and the roof membrane attached to the annular base body is radially formed so as to correspond to the connected portions of the small-diameter circular arcs. , The roof membrane is bulged in a petal-like manner between the recessed grooves so that the enlarging roof membrane divides the strength at the petal-shaped bulged portion and takes charge. Can increase the restraint force of the roof membrane.
