Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a floating structure for floating structures,

The present invention relates to a foot plate for anti-slip structure and a method of manufacturing the same, and more particularly, to a foot plate for float prevention in a floating cage culture facility, floating cage, In the manufacture of a scaffold for the purpose of movement, a sliding member is coated with a coating member to prevent slippage even if water is deposited on the upper side of a certain width of the polyethylene, thereby preventing a safety accident. And a manufacturing method thereof.

Generally, various types of structures are installed along the freshwater or sea surface or the water side, and they are used for various purposes such as fishing and sightseeing.

These floors are used to prevent slippage on floors in floating flooded cages, floating floors, marine mooring facilities, water pensions, beaches, and construction sites.

The buoyant structure is formed by extruding and molding polyethylene in a longitudinal direction. The buoyant body is connected to the buoyant body by a connecting bracket, and a worker or the like is placed on the buoyant body. A planar footrest is fixed so that it can be moved.

However, since conventional water structures are installed and used for a long period of time in the water or the vicinity thereof, they are exposed to waves or water at the bottom of the footplate, so that they are always wet, or algae or algae are attached.

When the surface of the scaffold is floated in the water as described above, when the worker or the like moves, it is slippery and hinders the walking of the pedestrian, so that it is inconvenient to remove the water from time to time.

Particularly, the molten raw material, which was originally filed by the present applicant, is extruded in the form of a panel in an extruder, and then pressed between the lower support roller and the grooved forming roller on the side of Patent Registration No. 0478720 (registered on Mar. 15, 2005) To form a non-slip protrusion, and to cut a predetermined length to form a hole in the foot plate.

However, since the foot plate prevents slippage through the non-slip projections formed by the molding rollers, the slippage prevention effect can be obtained in a situation where water is not applied since the foot plate is formed only of unevenness by the synthetic resin material. However, There is a drawback that a slippery phenomenon occurs and a safety accident often occurs and a knee is brought into contact when a worker is working for a long time because there is a rugged portion on a foot plate at the time of work, so that it is impossible to work for a long time by pressing.

In addition, it has been disadvantageous in that recycling is not easy since it is manufactured by bonding different plastics to each other.

(Document 1). Patent Registration No. 0478720 (registered on Mar. 15, 2005) (Document 2). Patent Registration No. 1681289 (registered on November 24, 2016) (Document 3). Patent Registration No. 1283664 (Registered on Mar. 07, 02, 2013) (Document 4). Patent Registration No. 0920086 (Registered on September 25, 2009)

Accordingly, it is an object of the present invention to provide a dual structure of an eco-friendly foot plate having excellent mechanical properties and physical properties to prevent slippage in a water structure.

Another object of the present invention is to provide an olefin elastomer which is located on the upper side, so that even when the operator kneels and works for a long time, the press is not applied, thereby facilitating the work.
