Mounting device and method for wall bracket of AP1000 steam generator

The invention belongs to the field of nuclear power equipment mounting and particularly relates to a mounting device and method for a wall bracket of an AP1000 steam generator. According to the novel mounting device for the wall bracket of the AP1000 steam generator, the problems that when the wall bracket of the AP1000 steam generator is welded and fixed to an equipment compartment wall, the position relationship between two bracket plates is uncontrollable, and mounting precision is not high are solved. The mounting device comprises a positioning piece, a connecting assembly, a supporting assembly and a limiting clamp. The two bracket plates are fixed to be a whole through the positioning piece. The mounting position of the wall bracket is adjusted and fixed through the supporting assembly. Accordingly in the welding process, the wall bracket can be adjusted precisely in height and angle at any time, the precision of the fixed position of the wall bracket is guaranteed, and the positions of the two bracket
