Inventor: SUMINO MASAHIRO
IPC: E04B1/64
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To conduct reinforcement by a steel plate for reinforcement surely even without scraping treatment. SOLUTION: In the reinforcing method of the steel structure, a rust layer 2 existing on the surface of a substrate steel material 1 is coated with an epoxy resin first (a). It is preferable that ketimine is used as the curing agent of the epoxy resin at that time. Since amine formed by a reaction with water contribute to the curing of the epoxy resin in ketimine, the formation of amine, the curing of the epoxy resin, is delayed and fluidity is maintained for a prolonged time when the rust layer 2 having little moisture is coated with the epoxy resin using ketimine as the curing agent, and the epoxy resin can be permeated deeply into the rust layer 2. The rust layer 2 on the surface of the foundation steel material 1 is coated with the epoxy resin 3 (b).  A steel plate 5 for reinforcement is superposed on the coated surface 4 of the epoxy resin while bolts 6 are inserted into through-holes 7 formed to the steel plate 5 for reinforcement and screwed into the holes 8 of the foundation steel material 1, and the steel plate 5 and the foundation steel material 1 are joined.
