PROBLEM TO BE SOLVED: To provide a method for preventing the contact corrosion of different metals at the time of joining stainless steel members of column and columns, columns and beams, beans and beams, columns and roofs, beams and roofs, etc., of buildings to each other by means of high-strength bolts made of steel. SOLUTION: At the time of fastening the parts consisting of stainless steels 1 by using steel bolts 2, part or the whole of the clearances formed on the outside surfaces of the bolted parts is covered by using the stainless steel and the metal 4 potentially baser than the steel or a layer of such metal is formed in part or the whole within the clearances exposed on the outside surfaces of the bolted parts. At the time of forming the coating film or thermally sprayed film contg. the metal having a sacrificial corrosion preventive effect or the layer of the metal within the clearances in such coating, it is also possible to use washers made of the metal having the sacrificial corrosion preventive effect or to use the washers subjected to plating by such metal or to form the plating layer of such metal in part in the clearances or the entire surface thereof or to form the layer of fats and oils or resins contg. the powder of such metal within the clearances. |
