To provide a bridge bearing exchange method capable of easily connecting and fixing an existing concrete beam and a new bearing and improving an aseismatic performance, and an attaching member for bearing exchange to be used at the time.
The bridge bearing exchange method includes: a process of removing an existing bearing 6 on a lower structure 4; a process of exposing reinforcing bars 14 by chipping work at a part of the side face and lower surface of the existing concrete beam 1 which is an upper structure; a process of disposing the attaching member for the bearing exchange including a steel bottom plate part and reinforcing and fixing parts, which are arranged on both sides of the bottom plate part at a predetermined interval in a bridge axial direction and which are projecting to the inner side of the exposed reinforcing bars 14, on the outer side of the concrete beam; a process of arranging a mold between the concrete beam and the attaching member for the bearing exchange, filling a solidifying filler and integrating the concrete beam and the attaching member for the bearing exchange; and a process of fixing the new bearing arranged at the lower structure to the bottom plate part of the attaching member for the bearing exchange.
