When installing the eccentric support on the super-high-rise steel beam, the worker aligns the mounting holes on one of the eccentric supports with the mounting holes on the steel beam horizontally and vertically, inserts screw one, and then screws nut one on screw one to lock and fix the eccentric support. Then, the mounting holes on the other eccentric support and the holes on the mounting plate on the eccentric support installed on the steel beam are horizontally and vertically aligned, screw two is inserted, and nut two is screwed on to lock, and the other end is locked with screw one and nut one, thereby connecting the eccentric support to the super-high-rise steel beam.
