Description
The present invention relates to a floating structure which is floated on the surface of fresh water or seawater, such as a floating structure such as a floating bridge, a barge, a cage farm, a ship mooring facility, a water pension, .
Currently, a variety of floating aquifer structures are installed along the freshwater or sea level or along the waterfront. Such a water structure is known as a mooring facility disclosed in Patent Document 1, for example.
In the marine structure disclosed in Patent Document 1 below, a buoyant body made by joining a buoyant pipe having a certain length formed by extrusion molding with polyethylene in a longitudinal direction by a plurality of heat fusion bonding is used. The buoyant pipe is inserted into a lower hole of the connection bracket And is supported by a connection bracket. A plurality of foot plates made of a generally square pipe are continuously arranged on the upper surface of the connection bracket in a transverse direction and fixed to the connection bracket by fastening means such as a bolt or the like.
However, the above-described conventional water structure has various problems in the environment where it is installed to be floated on the water surface at all times. In the case of buoyant pipes, they come into contact with water for a long time on the water surface, so that crustaceans and shellfish are attached to the surface as well as adherent algae. When such surface-adhered creatures adhere to the surface of the buoyancy tube, corrosion of the structure is promoted, thereby decreasing durability and increasing the weight of the structure, thereby gradually reducing the buoyancy. In order to solve these problems, most of them have been coated with antifouling paints on the flooded areas of the water structures. However, the coated antifouling paints need to be repaired periodically due to the fact that they are peeled off from the water structure over time. However, in the water-borne structure, the portion requiring the repair work of the antifouling paint is flooded, so that the repair work is not easy.
Further, in the case of the foot member, there is a disadvantage that it is difficult to walk on the foot member due to being slippery since the surface is always wet with water. In order to solve such a problem, conventionally, when forming a foot member, anti-slip irregularities are formed on the surface. However, since the unevenness of the surface of the foot member is made of the same material as that of the foot member, that is, made of polyethylene resin, there is a problem that abrasion is easily occurred and the life span is short and the slip prevention function can not be sufficiently exhibited after a lapse of time.
Accordingly, the present invention has been devised to solve the disadvantages of the conventional water structure, and it has an improved anti-fouling performance without using an antifouling paint on a component that is always immersed in water, and a slip prevention function The purpose is to provide a water structure together.
To achieve the above object, the present invention provides a water-
And a plurality of aquaplane units arranged continuously in the transverse direction and joined or joined to each other so as to adjoin each other,
A buoyancy pipe formed by extruding a resin composition containing polyethylene and having at least one rotation preventive protrusion formed by extrusion in the longitudinal direction on an outer circumferential surface thereof; The buoyancy pipe is provided on the outer periphery of the buoyancy pipe so that the anti-rotation protrusions of the buoyancy pipe are fitted in the coupling grooves in a shape-fit manner. The upper end of the buoyancy pipe has a plurality of stepped member mounting grooves each having a constant width. At least one supporting bracket provided with a plurality of coupling projections and having opposite engaging holes corresponding to the coupling projections adjacent in the lateral direction on the opposite side walls; And a plurality of foot members which are mounted on the foot member mounting grooves of the support bracket and fixed to the support bracket by a fixing bolt.
In order to impart an antifouling function to the buoyancy pipe, the present invention is molded by extruding a resin composition obtained by mixing an antifouling agent with polyethylene. The resin composition for buoyancy tube comprises 45 to 80% by weight of polyethylene as a base resin; 1 to 10% by weight of a formaldehyde-based copolymer as an antifouling agent; 10 to 40% by weight of an inorganic filler; 1 to 10% by weight of a silicone polymer for promoting the self-polishing function of the antifouling agent to impart a stable wear rate to the antifouling agent; 1 to 5% by weight of an antioxidant; And 1 to 5% by weight of a UV stabilizer are extruded and molded.
Here, the formaldehyde copolymer used as the antifouling agent is mixed with polyethylene, which is a base resin, as a material for preventing adhesion and growth of adherent organisms such as barnacles, shellfishes, seaweeds and the like on the outer surface of the finally formed buoyancy tube .
The silicone polymer is a polymer material that promotes the self-polishing function of the antifouling agent mixed with polyethylene and provides a stable wear rate of the antifouling agent.
Antioxidants and UV stabilizers are extrudable polymers and serve to minimize the loss of compatibility with the antifouling agent and loss of function.
In the case of the present invention, since the antifouling agent is contained in the active ingredient polyethylene in the raw material blending step before the buoyancy tube is formed by extrusion, The antifouling performance is given to the buoyancy pipe semi-permanently without peeling of the antifouling paint from the surface of the buoyancy pipe.
The foot plate member may have a rectangular cross-sectional shape having a predetermined width and height, and may include a hollow square pipe formed by extruding polyethylene so as to have a plurality of hollows along its length in the longitudinal direction for weight reduction, a thermoplastic rubber, TPR ') as an active ingredient, and a non-slip layer laminated on the surface of the hollow square pipe. A plurality of anti-slip protrusions are formed on the surface of the anti-slip layer in a predetermined pattern.
The thermoplastic rubber of the anti-slip layer may include 45 to 60 parts by weight of low density polyethylene (LPDE); 20 to 40 parts by weight of styrene-ethylene-butylene-styrene block copolymer (SEBS); 13 to 25 parts by weight of oil; 5 to 10 parts by weight of calcium carbonate; And 35 to 40 parts by weight of a phosphorus flame retardant.
The phosphorus flame retardant is preferably a mixture of at least one selected from the group consisting of magnesium hydroxide, aluminum hydroxide and magnesium carbonate.
According to the present invention, since the buoyant pipe which is floated on the water surface and is always in contact with the water surface is formed by including the antifouling agent, it has an antifouling function and, furthermore, the antifouling agent, It is possible to provide the antifouling performance to the buoyant pipe semi-permanently without peeling off the antifouling paint on the surface of the buoyancy pipe after a lapse of a predetermined time as in the case of coating the antifouling paint on the surface after forming the buoyancy pipe. .
In addition, the slip prevention layer formed of the thermoplastic rubber is provided on the foot member of the water structure, which is always exposed to the aquatic environment, so that the operator or the walker can safely walk and work on the water structure.
The thermoplastic rubber used as the material of the anti-slip layer is excellent in adhesiveness only by extrusion molding into the base pipe of the foot member without the vulcanization step, and wear resistance or durability is ensured even for a long time of use. Further, since the thermoplastic rubber can be bonded to the surface of the hollow square pipe of the PE material which is the base pipe by secondary extrusion, the production process is simple and the production cost can be reduced.
Particularly, the foot member having the slip prevention function of the present invention is excellent as a slip prevention function in comparison with the case where embossed protrusions are formed on a square pipe of a PE material, so that it is suitable as a foot member for a water structure that contacts water for a long time.
