PROBLEM TO BE SOLVED: To provide an aseismatic reinforcing structure for an existing building, capable of suppressing decrease in light entering inside the existing building even when the aseismatic reinforcing structure is installed on an outer surface of the existing building.SOLUTION: An aseismatic reinforcing structure 1 includes: an extension beam 30 formed on a column-beam connection part of an existing building; a pin 40 fixed to the extension beam 30; and an outer shell reinforcing frame 20 installed on an outer surface of the existing building and having an outer shell column 21 and an outer shell beam 22 joined in a lattice form. A pin hole to be connected with the pin 40 is formed on the outer shell reinforcing frame 20, and the pin hole is positioned lower than a joining position 50 of the outer shell column 21 and the outer shell beam 22. The extension beam 30 is formed along the lower side of a protruded part 13 protruded from the existing building to the outer side, and a lower end of the outer shell beam 22 is positioned in the same position with a lower end of the protruded part 13 or is positioned higher than that of the protruded part 13. |
