Earthquake damage coupling beam reinforcing device and method

The invention belongs to the technical field of earthquake damage building repairing, and particularly discloses an earthquake damage coupling beam reinforcing device and method.The reinforcing device comprises two first frame sets, a rod set and two second frame sets, the first frame sets are oppositely arranged, and the second frame sets are oppositely arranged; the first frame set and the second frame set form a reinforcing assembly surrounding the exposed side face of the earthquake damage connecting beam, and the rod set is used for connecting the first frame set and the earthquake damage connecting beam. The reinforcing method comprises the steps that mounting grooves are formed in the upper end and the lower end of the earthquake-damaged coupling beam, through grooves penetrating through the earthquake-damaged coupling beam are formed in the non-earthquake-damaged part of the earthquake-damaged coupling beam, first frame sets are arranged on the mounting grooves, rod sets penetrate through the through
