DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing corrosion of a pipeline or a steel structure of a bridge as a complex structure near a coast.

[0002]

2. Description of the Related Art Conventionally, as a method of corrosion protection of a pipeline near a coast or a structure in a zone contaminated with air or a steel frame, as shown in FIG.
The method of coating the paste tape 4 after applying the paste 3 to the surface of the steel pipe has been widely adopted for preventing salt damage or acid rain, and is well known. An anticorrosion material is applied, and the top is covered with anticorrosion tape, and as a protective cover, a flat sheet made of polyolefin resin reinforced with a long fiber glass mat and provided with resin angles at both ends, bolts and nuts It is also possible to cover by attaching with
It is disclosed in the official gazette of the Japanese Patent Application Laid-Open Publication No. HEI 10-203, and is known.

[0003]

SUMMARY OF THE INVENTION The inventor of the present invention does not merely cover the corrosion-resistant base material with a paste tape whose effects such as corrosion protection, heat retention, and heat insulation of the corrosion-resistant base material decrease over time. Even if a corrosion-resistant / reinforcement coating is provided on the paste tape coating, a corrosion-resistant construction method that can easily coat steel frames such as bridges or corrosion-resistant base materials such as pipes of pipe pipelines without using bolts and nuts in the pipe body As a result of studying the above, the present invention was achieved.

[0004]

According to the present invention, a paste is applied to the outer surface of a corrosion-resistant base material after the outer surface of the anti-corrosion base material is prepared by preparing a base material, and a paste tape is densely applied to the surface to which the paste application is applied. And a water-based paint is applied to the surface to be applied, and then a reinforcing material impregnated with the water-based paint is applied, and a water- and oil-based paint for coloring is further applied. This is a coating method using paste tape.

[0005] The corrosion-resistant base material in the present invention means a steel material requiring rust prevention, such as a steel frame of a bridge or a pipe of a pipeline.

[0006] The reinforcing cloth according to the present invention includes synthetic fibers,
It means cotton cloth, linen cloth, non-woven fabric, felt, glass wool, etc., and is preferably a felt or glass wool mat which can be impregnated with an aqueous paint.

[0007] In pasting the reinforcing cloth in the present invention, pasting a paste tape to the surface to which the paste is applied is as follows.
This is because when the paste tape is closely adhered to the anticorrosion base material, it also has a rust preventing effect. Further, after applying the water-based paint on the paste tape application surface, coating the coated surface with a reinforcing material impregnated with the water-based paint,
This is because the reinforcing material can be stuck more strongly.

[0008] Colored water-based or oil-based paint is applied because not only can the obtained pipeline or bridge be beautiful, but also the pipeline can be identified.

In addition, without applying a coloring paint,
The coloring paint can be impregnated into a reinforcing cloth, or can be adhered onto the reinforcing material while being impregnated with aqueous penite.

[0010]

Example 1 The outer surface of a corrosion-resistant base material was subjected to a base treatment, if necessary, with a target of international standard ASa3, and then a paste was applied to the surface to a sufficient thickness, and the surface was coated with the paste. , Immediately paste the paste tape in close contact, apply the aqueous paint on the application surface, and then apply a reinforcing material made of glass wool felt impregnated with the aqueous paint, and then apply the colored oil-based paint. , Where appropriate.

[0011]

According to the present invention, the paste tape, the water-based paint, and the reinforcing material are integrated to keep the surface of the anticorrosion base material covered for a long period of time, and to provide effects such as anticorrosion, heat retention, heat insulation, and color retention. Thus, a corrosion-resistant construction method capable of maintaining the above was obtained.
