Repair structure and repair method for corrosion joint of steel civil engineering structure

摘要

PROBLEM TO BE SOLVED: To provide a repair structure for a corroding junction in a steel civil engineering structure which eliminates the risk that a constituent member of the steel civil engineering structure is damaged by fusion cutting or the like of a bolt or an object attached to the steel civil engineering structure falls down, and a repair method.SOLUTION: The present invention relates to a repair structure 1 for a corroding junction in a steel civil engineering structure D1. The repair structure includes: a corroding junction 2 which is joined by a corroding joint member B' that is corroding and deteriorated; and a coupling steel material 3 which is abutted over multiple constituent members joined by the corroding junction 2. The coupling steel material 3 includes: a separation space RS which detours and separates from a surface of the constituent members (D3, D51, and D52) joined by the corroding junction 2 for as long as or longer than a predetermined distance; and a pair of linear protruding ends 31d and 32d which are provided at positions interposing the separation space RS therebetween. In the coupling steel material 3, the protruding ends 31d and 32d are abutted to the surface of the constituent members joined by the corroding junction 2 for as long as or longer than the predetermined distance, and both sides of the abutted protruding ends 31d and 32d are welded to the constituent members.SELECTED DRAWING: Figure 5
