Description

Technology Field

[0001] The present invention relates to a prefabricated modular buoyancy body, and more specifically, to a prefabricated modular buoyancy body that can be utilized for various purposes, such as small barges, small pontoons, and rafts, by being manufactured by continuously assembling several unit buoyancy bodies. Background Technology

[0003] Generally, buoyancy bodies are devices that float by buoyancy in coastal aquaculture facilities, connected to nets or growth plates, or function as buoys; they take on various shapes and forms, such as spherical, cylindrical, or rectangular.

[0004] These buoyancy devices are primarily manufactured by foam molding of rubber or synthetic resin materials; representative examples include expanded polyethylene (PEP), expanded polypropylene (EPP), and expanded polystyrene (EPS).

[0005] The above materials have the characteristic of being able to obtain high buoyancy because they are very light relative to their volume, as small air holes formed by porous bubbles are formed inside during foam molding.

[0006] However, since conventional foamed buoyancy devices are mostly organic compounds based on various plastic materials such as rubber or polymer compounds, damage caused by corrosion and deterioration due to strong ultraviolet rays from sunlight on the water surface progresses relatively quickly. Furthermore, in the ocean, corrosion caused by the salt in seawater is compounded, resulting in a short service life as a buoyancy device. In particular, environmental pollution problems arise, such as microplastics, which are environmental pollutants, leaching out and dispersing into the water due to deterioration and corrosion.

[0007] In addition, the foamed buoyancy bodies mentioned above have weak surface strength and are easily deformed or damaged by external impacts like sponges. Furthermore, there were particularly many difficulties in the process of connecting and combining multiple foamed buoyancy bodies in succession when manufacturing floating structures for various purposes, such as small pontoons, rafts, and small barges that float on the surface of the sea.

[0008] In addition, when connecting unit buoyancy bodies in series, connecting members are required to ensure a rigid connection between them; however, if the connecting members protrude outward from the unit buoyancy bodies, there is a possibility that they may be damaged by external collisions, which could lead to the problem of the connection between the unit buoyancy bodies becoming loose.

[0009] Meanwhile, the following prior art documents disclose only the contents regarding an eco-friendly buoy for foam molding and a method for manufacturing the same, but do not disclose the technical essence of the present invention. Prior art literature

Specific details for implementing the invention

[0029] Preferred embodiments according to the present invention will be described in detail with reference to the attached drawings, provided that identical or similar components are given the same reference number regardless of the drawing symbols, and redundant descriptions thereof will be omitted.

[0030] Furthermore, in describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such descriptions could obscure the essence of the invention. Additionally, it should be noted that the attached drawings are intended only to facilitate an understanding of the concept of the present invention and should not be interpreted as limiting the concept of the present invention.

[0032] The prefabricated modular buoyancy body according to the present invention will be described below with reference to FIGS. 1 to 6.

[0033] The prefabricated modular buoyancy body according to the present invention is basically configured to include a plurality of unit buoyancy bodies (100) and prefabricated wires (200) as shown in FIG. 1.

[0034] The unit buoyancy body (100) is formed of a material that floats on water because its weight per unit volume is lighter than that of water, and, for example, can be made of a foamed buoyancy body formed by foaming a synthetic resin material into a predetermined shape. Preferably, the surface strength of the unit buoyancy body (100) can be increased by spraying a predetermined composition onto the surface of the foamed buoyancy body to form a coating layer of a predetermined thickness. At this time, the coating layer may be composed of at least one of a mixture containing inorganic cement and a predetermined organic compound.

[0035] In particular, a shotcrete coating layer can be considered as a coating layer. This shotcrete coating layer is formed by spraying a shotcrete composition mixed with 10 to 30 weight percent of fiber reinforcement at high pressure. The shotcrete composition sprayed at this time may be any one of a cement milk or cement paste having a basic mixture of water and cement, a cement mortar having sand additionally mixed into the basic composition, or a cement concrete having sand and gravel mixed into the basic composition. Since this shotcrete composition is a technology used in ordinary construction sites, a description of the specific composition and mixing ratio will be omitted.

[0036] Meanwhile, the fiber reinforcement mixed into the shotcrete composition of the present invention is thin with a diameter of 0.5 to 1 mm and a length of 3 to 50 mm, and it is preferable to use any one of steel fibers, nylon fibers, polypropylene fibers, PET fibers, PVA (polyvinyl alcohol) fibers, cellulose fibers, glass fibers, and carbon fibers.

[0037] When such high-pressure shotcrete spraying is performed, the shotcrete composition penetrates into the foam pores on the surface of the foamed buoyancy body due to the spraying pressure, thereby achieving efficient surface adhesion. It is preferable that the shotcrete spraying be carried out using the wet method among the dry and wet methods.

[0038] In addition, to improve the functionality of the shotcrete, it is desirable to add carbonitride and metallocene polyethylene components in an amount of 5 to 10 weight percent each relative to the total weight. Due to the mixing of these functional components, the curing time of the coating layer can be shortened and durability can be strengthened. In particular, metallocene polyethylene can exhibit the advantage of improving the bonding strength and density between paste particles through the catalytic function of the cement paste.

[0039] Furthermore, depending on the circumstances, a shotcrete composition mixed with fiber reinforcement as described above may be applied as a plaster to the outer surface of the foamed buoyancy body.

[0040] Meanwhile, a horizontal through hole (110) may be formed with a preset size to penetrate horizontally in each direction, horizontally and vertically, in a predetermined part of the unit buoyancy body (100). It is preferable that the horizontal through hole (110) penetrating in the horizontal direction and the horizontal through hole (110) penetrating in the vertical direction be formed with a height difference so that they do not come into contact with each other and intersect.

[0041] The assembly line (200) performs the function of forming a single assembly buoyancy body by inserting the assembly line (200) collectively into the horizontal through holes (110) of a plurality of unit buoyancy bodies (100) and combining the plurality of unit buoyancy bodies (100) in the horizontal or vertical direction.

[0042] That is, two or more unit buoyancy bodies (100) are provided so as to be connected and in contact with each other in one direction or both directions, horizontally, vertically, or vertically, and at the part where the unit buoyancy bodies (100) are in contact with each other, the ends of each horizontal through hole (110) of each unit buoyancy body (100) are arranged so as to be in contact with each other and in a continuous manner, and two or more unit buoyancy bodies (100) are connected by inserting the assembly wire (200) into each through hole (110) continuously without interruption.

[0043] At this time, it is preferable that both ends of the assembly member (200) be formed with a predetermined length so that they can protrude by a predetermined length to the outside of the assembly buoyancy body, that is, to the outside of the unit buoyancy body (100a) placed at the outermost edge.

[0044] Meanwhile, the assembly wire (200) can be formed into a long, slender shape made of flexible fiber-reinforced plastic (GFRP, CFRP, AFRP) material, and in particular, the assembly wire (200) made of fiber-reinforced plastic material prevents corrosion even when in contact with water, especially seawater, has very high tensile strength, and due to its excellent flexibility, it can stably maintain a modular assembly state between multiple unit buoyancy bodies (100).

[0045] Hereinafter, a prefabricated modular buoyancy body according to one embodiment of the present invention will be described with reference to FIG. 2 and FIG. 3.

[0046] A receiving space (120) is formed on the outer side of a unit buoyancy body (100a) placed at the outermost edge of a prefabricated buoyancy body formed by combining multiple prefabricated buoyancy bodies, by cutting out a predetermined size and a predetermined depth as shown in FIG. 2.

[0047] A tightening device (300) is placed within the receiving space (120) as shown in FIG. 3, and the tightening device (300) is configured in the form of a nut or a wedge, and is coupled to both ends of the assembly line (200) to ensure a strong connection between multiple unit buoyancy bodies (100).

[0048] That is, by tightening the tightening device (300), a tightening force is applied to the assembly line (200), and a state of close contact is achieved between each unit buoyancy body (100). Since the tightening device (300) is placed within the receiving space (120) without protruding from the assembly buoyancy body, the possibility of damage caused by collision with the outside can be minimized.

[0049] Hereinafter, a prefabricated modular buoyancy body according to a second embodiment of the present invention will be described with reference to FIGS. 4 and FIGS. 5.

[0050] The prefabricated modular buoyancy body according to the second embodiment of the present invention is configured to further include a mooring ring member (400) shown in FIGS. 4 and FIGS. 5.

[0051] The mooring ring member (400) is formed to allow a rope or the like to be attached so that the prefabricated modular buoyancy body can be moored in a specific area of ​​the coast or water surface.

[0052] Specifically, one end of the rope is connected to a mooring ring member (400), and the other end of the rope is configured to be connected to a fixed member, such as an anchor placed on the coast or underwater, thereby preventing the prefabricated modular buoyancy body from floating away from a specific area.

[0053] These mooring ring members (400) are placed on a unit buoyancy body (100a) positioned at the outermost edge of the prefabricated buoyancy body as shown in FIG. 4, and are configured to include a mooring plate (410), a protrusion (420), and a mooring ring (430).

[0054] The mooring plate (410) is formed as a flat plate of a predetermined shape having a predetermined thickness and width, and a hole (410) of a predetermined size is formed in the middle area.

[0055] The protrusion (420) has a predetermined thickness and a predetermined width and is made of the same material as the mooring plate (410), and is configured to protrude from both the left and right sides of the mooring plate (410) by a predetermined length in a direction perpendicular to the plane of the mooring plate (410).

[0056] At this time, as shown in FIG. 5, it is preferable to insert the end of the assembly line (200) into the hole (411) of the mooring plate (410) so that the protrusion (420) faces outwardly toward the assembly buoyancy body, and then fasten the tightening device (300) to the end of the assembly line (200) to fix the mooring plate (410) inside the receiving space (120).

[0057] The mooring ring (430) is configured to include a semicircular portion (431) formed of a predetermined material and thickness, and a bent portion (432) bent to a predetermined length at both ends of the semicircular portion (431).

[0058] In particular, a protrusion hole (421) formed with a preset size is formed at a predetermined portion of the end of the protrusion (420) that protrudes outward from the receiving space (120), and the bent portion (432) of the mooring ring (430) described above is configured to be inserted through the protrusion hole (421).

[0059] Hereinafter, a prefabricated modular buoyancy body according to a third embodiment of the present invention will be described with reference to FIG. 6.

[0060] As shown in FIG. 6, the prefabricated modular buoyancy body according to the third embodiment of the present invention is configured to fill the remaining part of the receiving space (120) with a material (500) made of a preset material, while at least one of a tightening device (300) and a mooring plate (410) is present inside the receiving space (120) of the outermost unit buoyancy body (100a).

[0061] Through this, the clamping device (300) or mooring ring member (400) can be firmly fixed to the prefabricated buoyancy body, and through this, a sturdy and stable prefabricated buoyancy body can be manufactured.

[0063] Although the present invention has been described in detail using preferred embodiments, the scope of the invention is not limited to specific embodiments and should be interpreted by the appended claims. Furthermore, those skilled in the art will understand that many modifications and variations are possible without departing from the scope of the invention. Explanation of the symbols
