METHOD FOR MANUFACTURING INCOMBUSTIBLE FIBER REINFORCED PLASTIC ROD, AND REINFORCING METHOD OF TUNNEL USING THE ROD

摘要

The present invention relates to an incombustible fiber reinforced plastic reinforcement rod that is disposed in a tunnel instead of a rebar to reinforce tunnel strength and is formed of an incombustible material not damaged by fire, a method for manufacturing same, and a repair reinforcement technique for a concrete structure using same. The incombustible fiber reinforced plastic reinforcement rod according to the present invention includes a core rod formed of an inflammable or incombustible resin material in which a long rod-shaped reinforcement wire material which is formed into a solid body by mixing a phenol resin or a melamine resin and glass powder is inserted to extend in one direction therein; and an incombustible outer shell material that is formed by dipping an inflammable fiber into a resin solution which is produced by mixing a methylol melamine resin with an inorganic inflammable material, dispersing through a solvent injection, and then diluting in water and is directly bonded through heating and compression to an outer surface of the core rod at a predetermined temperature and pressure in a state of half-dried prepreg.
