PROBLEM TO BE SOLVED: To provide an existing building reinforcing method which is implemented by setting a peripheral frame on the periphery of a beam-column frame, and arranging braces in the peripheral frame, wherein the method facilitates adjustment of a dimensional error of an existing skeleton even if it has one. SOLUTION: The reinforcing structure 10 is formed of: the peripheral frame 20 which is mounted at least on upper and lower surfaces out of internal peripheral surfaces of a rectangular opening 5 formed in a post-beam frame 1 enclosing the opening 5 of the existing building; and brace members 30 which are arranged so as to connect between sections of the peripheral frame 20 mounted on the upper and lower portions of the opening 5. According to the reinforcing structure, steel pipes 21, 31 are arranged at locations corresponding to the peripheral frame 20 and the brace members 30, and mortar grout 22 is placed in a manner forming a unitary body with the steel pipes 21, 31. The steel pipe 21 is bonded at least to the upper and lower surfaces out of the internal peripheral surfaces of the opening 5 by an adhesive 25. Further the steel pipes 21, 31 are each divided into two or more sections, and joint reinforcements 23 and stress transmitting reinforcements 40 are arranged between the divided steel pipes 21, 31, respectively.
