Repairing method of concrete structure, segment of repair structure and shielding method

摘要

PROBLEM TO BE SOLVED: To solve the problem in which when an explosion-proof fireproof concrete structure having organic fiber mixed is repaired with an explosion-proof fireproof repair material having organic fiber mixed, a fire with large force may cause peeling and explosion in spite of the explosion-proof fire proof properties.SOLUTION: An explosion-proof, fire-proof concrete structure is prevented from peeling and exploding by a repair method etc., including the processes of: (a) installing a fitting member at a damage part; (b) coating the damage part with an explosion-proof, fire-proof repair material having organic fiber mixed; (c) arranging a reinforcing material on the explosion-proof, fire-proof repair material; (d) expanding the explosion-proof, fire-proof repair material from a gap of the reinforcing material by pressing the reinforcing material against the applied explosion-proof, fire-proof repair material, and thereby fixing the reinforcing material through the fitting member; and (e) covering the top of the reinforcing material with an explosion-proof, fire-proof repair material.
