Claims (6)

The main body of a polygonal column body having buoyancy; and A male fastening portion formed protruding outwardly on one or more of the side surfaces of the main body portion; and It includes a female fastening part formed by being inwardly recessed on one or more of the side surfaces of the main body that do not overlap with the side surface where the male fastening part is formed, A unit floating structure for constructing an offshore city, wherein the male connecting part and the female connecting part are formed to have corresponding shapes and sizes.
In paragraph 1, An insertion hole is formed in the above main body portion, extending from the upper surface of the main body portion to the inner space of the female fastening portion, and is formed by penetrating in a vertical direction. In the above-mentioned male fastening part, a fastening groove of a predetermined depth is formed in the vertical direction, A unit floating structure for constructing an offshore city, wherein the male connecting part of another unit floating structure located adjacently in the lateral direction is inserted into the inner space of the female connecting part of the unit floating structure, and when the insertion hole and the connecting groove are positioned in the vertical direction, a fixing pin inserted through the insertion hole is inserted together into the insertion hole and the connecting groove, thereby fixing the lateral connection state between the unit floating structure and the other unit floating structure.
In paragraph 1 or 2, A unit floating structure for constructing an offshore city, wherein the protruding end region of the above-mentioned male connecting part is formed in a tapered shape that becomes relatively narrower as it progresses outward.
In paragraph 1, If the main body has a polygonal shape with an even number of sides when viewed from above, the side surfaces on which the male fastening part or the female fastening part is formed alternate with each other, and the unit floating structure is manufactured such that the number of side surfaces on which the male fastening part and the female fastening part are formed is the same. A unit floating structure for constructing an ocean city, wherein if the main body has a polygonal shape having an odd number of sides when viewed from above, the side surfaces on which the male fastening part or the female fastening part is formed alternate with each other, and each is manufactured into two types of unit floating structures in which the number of side surfaces on which either the male fastening part or the female fastening part is formed is greater.
In paragraph 1, A unit floating structure for constructing an ocean city, wherein the main body has a hollow area formed inside or a recessed area formed at the bottom, and the hollow area or the recessed area is filled with a buoyancy body.
In paragraph 1, The above main body is moored at sea as a fixed offshore structure using a pile assembly, The above pile assembly is a unit floating structure for constructing an offshore city, comprising a fixed structure fixed to the seabed and a column-shaped pile connecting the fixed structure and the main body.

Description

Unit floating structure for building a marine city The present invention relates to a unit floating structure for constructing an offshore city. The risk of coastal flooding is increasing due to rising sea levels caused by global warming, and in the case of some island nations, the threat of submersion is even being raised. As a way to respond to these risks of climate change while simultaneously creating new residential spaces for population growth, interest in constructing marine cities is growing. Research on the construction of artificial islands for the construction of marine cities has been conducted for a long time, and the methods of constructing artificial islands are diverse, including the reclamation type, which creates land by pouring soil; the construction type, which creates land by pouring concrete onto reefs or the seabed; and the floating type, which fixes structures in the form of barges or platforms in the sea. However, conventional methods of constructing artificial islands at sea to build marine cities not only require massive construction costs, but also had the problem that adjusting the area was not easy after construction, even if it was necessary to expand or reduce the size of the artificial island. The matters described in the technical background section of this invention are for the purpose of understanding the background of the invention and cannot be concluded as prior art already known to a person with ordinary knowledge in the field to which this technology belongs. FIG. 1 is a drawing illustrating the shape of a unit floating structure according to one embodiment of the present invention. FIG. 2 is a drawing illustrating a lateral connection form of a unit floating structure according to one embodiment of the present invention. FIG. 3 is a diagram showing the process of fastening unit floating structures according to one embodiment of the present invention. FIG. 4 is a drawing illustrating the shape of a unit floating structure according to another embodiment of the present invention. The present invention is capable of various modifications and may have various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

In the accompanying drawings, identical components are given the same reference numerals, and in the description of the embodiments, identical or corresponding components may be briefly described or redundant descriptions may be omitted. In the description of the embodiments, terms such as "first," "second," etc., are used merely to distinguish identical or similar components and are not intended to limit each component to a specific purpose. In the drawings, each component may be depicted in an exaggerated size for convenience of explanation and understanding, and it is obvious that the present invention is not limited to the size and proportion of the components depicted in the drawings. FIG. 1 is a drawing illustrating the shape of a unit floating structure according to one embodiment of the present invention, FIG. 2 is a drawing illustrating the lateral connection form of a unit floating structure according to one embodiment of the present invention, FIG. 3 is a drawing showing the fastening process of unit floating structures according to one embodiment of the present invention, and FIG. 4 is a drawing illustrating the shape of a unit floating structure according to another embodiment of the present invention. Referring to FIG. 1, the unit floating structure (100) includes a main body (110) of a polygonal column body having a predetermined volume. The main body (110) may be formed in a polygonal shape, for example, a square, triangle, hexagon, etc., when viewed from above. The polygonal shape of the main body (110) may be a regular polygon, for example, and the corners may be formed as pointed or rounded corners. The main body (110) may be made of a rigid material such as steel or concrete. Here, a hollow area may be formed inside the main body (110) or a concave depression may be formed in the lower part of the main body (110) so that the upper area protrudes above the water surface and floats, and a buoyancy material such as styrofoam may be filled into the formed hollow area or depression. Alternatively, a ballast system may be provided in the main body (110), and a ballast area may be formed as a space where seawater flows in or out inside the main body (110).
