Abstract

The present invention is concerned with the anticorrosive coating structure of JETTYPILE for supporting concrete structures of network facilities.

Conventionally, the upper surface of the jetty pile in contact with the concrete structure is laminated with anticorrosive paste, anticorrosive tape, and synthetic resin sheet in sequence, and covered with FRP cover to prevent oxidative corrosion due to exposure to repetition. In addition, the FRP cover is moved downward by the weight of the shells, which are fastened to the surface of the FRP cover by fastening the metal band with bolts and nuts, and welding them to the jetty file. The utility model is a marine jetty anticorrosive coating structure that prevents the shellfish and shellfish from entering the gap between the anticorrosive tape, synthetic resin sheet and the bottom of the FRP cover and shorten the life of the anticorrosive coating. It is known as the registered heading 0151960. However, it is possible to directly attach the top surface of the jetty pile to the concrete surface of the structure. Since the catalyst by doemeuro be sea water from entering the interior of the jetties file via the Push convex surface of the concrete due to the problem was to follow the inside of the jetty files quickly oxidation corrosion.

The present invention is coated with a water-soluble epoxy (SUB EPOXY) 14 to a certain thickness (about 20mm) on the concrete surface of the concrete structure 13 is in contact with the jetty pile 1 to solve the above problems and jetty pile The upper part of (1) is coated with a water-soluble epoxy (14 ') at a predetermined thickness (about 30 mm) to provide a perfect waterproof treatment to prevent the ingress of seawater into the jetty pile (1). The purpose is to provide an anticorrosive coating structure.

Description

COVERING STRUCTURE OF THE SEA JETTYPILE}

The present invention relates to the anticorrosive coating structure of JETTYPILE for supporting concrete structures of port network facilities.

It is a further improvement of the applicant's registered utility model No. 0151960.

The characteristics of the applicant's registration proposal is that the upper surface of the jetty pile in contact with the concrete structure is laminated with anticorrosive paste, anticorrosive tape and synthetic resin sheet in sequence, and covered with FRP cover and immersed in seawater due to the difference between tidal acid and corrosion. In addition, the metal band is fastened to the bottom of the coating coated on the surface of the jetty pile by bolts and nuts, and fixed by welding to the jetty pile. It prevents the FRP cover from moving downward and also prevents the inflow of shellfish and shellfish into the gap between the anticorrosive tape, the synthetic sheet and the bottom of the FRP cover to shorten the life of the anticorrosive coating.

Since the upper surface of the jetty pile is in direct contact with the concrete surface of the structure, the seawater flows into the interior of the jetty pile through the uneven portion of the concrete surface, thereby causing the problem of rapid oxidation of the interior of the jetty pile.

In order to solve the above problems, the present invention has coated a water-soluble epoxy (SUBEPOXY) 14 with a certain thickness (about 20 mm) on the concrete surface of the concrete structure 13 to which the jetty file 1 is in contact. The upper part of 1) is coated with a water-soluble epoxy (14 ') at a certain thickness (about 30mm) to provide a perfect waterproof treatment to prevent the ingress of seawater into the jetty pile (1) The purpose is to provide a covering structure.

As shown in FIGS. 1 to 2

A pair of FRP covers 5 and 5 having flanges 501 and 502 formed on the outer surface of the jetty pile 1, the anticorrosive paste 2, the anticorrosive tape 3, and the synthetic resin sheet 4, which are laminated in this order. ') With a bolt (6) and a nut (7) and a pair of metal bands (8) (8') formed with a piece of stone (8A) under the FRP cover (5) (5 ') bolt (9) And the nut 10, the protrusion 8A is fixed with the FRP cover 5, 5 ', the bolt 11, and the nut 12, and the metal bands 8, 8' are jetty piles 1. By welding to the concrete surface of the concrete structure 13, the water-soluble epoxy 14 is coated with a thickness of 20 mm, and the water-soluble epoxy 14 'is coated with an upper portion of the jetty file 1 with a thickness of 30 mm. It is characterized in that to prevent the inflow of seawater into the jetty file (1).

Reference numeral 15 is a weld.

The present invention is prevented from being oxidized by the anticorrosive paste 2, the anticorrosive tape 3, and the synthetic resin sheet 4 coated on the outer surface of the jetty pile 1 and the FRP cover 5, 5 ′. FRP cover (5) (5 ') due to the difference in tidal waves and waves by the metal bands (8) (8') fixed below, and the weight of fish and shellfish stuck to the FRP cover (5) (5 '). ) Is prevented from flowing downward, and foreign matter or shellfish and the like are prevented from entering the gap between the anticorrosive tape 3, the synthetic resin sheet 4, and the FRP cover 5, 5 '.

The above operation is the same as the conventional jetty file structure.

In the above, the present invention is coated with a water-soluble epoxy (14, 14 ') on the concrete surface of the concrete structure 13 and the surface of the jetty (1) to prevent the introduction of seawater into the interior of the jetty (1) Can be. Accordingly, since the inside of the jetty file 1 is oxidized and corroded, the service life can be prevented from being shortened.

The present invention has a water-soluble epoxy 14 having a thickness of 20 mm on the concrete surface of the concrete structure 13 to which the jetty pile 1 is in contact, and a water-soluble epoxy having a thickness of 30 mm on the surface of the jetty pile 1. 14 ') by coating a perfect waterproof treatment to prevent the inflow of seawater into the interior of the jetty pile (1) it is possible to prevent the oxidation corrosion to maintain the long life of the jetty file (1).
