ASEISMATIC REINFORCING METHOD FOR EXISTING BUILDING

PROBLEM TO BE SOLVED: To provide an aseismatic reinforcing method which has no adverse effect on the usability of a building and an interior design in an existing building having an external wall and furthermore dispenses with removal and restoration work of an interior material. SOLUTION: In the existing building with the external wall 6 attached to the outside of an existing steel column 2, an earthquake-resisting wall 10 made of precast concrete is prepared separately from the external wall 6, and a connecting projection 11 is integrally and protrusively provided on the back face side of the upper part of the earthquake-resisting wall 10. A fitting hole 7 for fitting the connecting projection 11 of the earthquake-resisting wall 10 is formed in the external wall 6, penetrating the front and rear of the external wall 6 at a part where the steel column 2 is located. The earthquake-resisting wall 10 is disposed on the outside of the external wall 6, with the connecting projection 11 fitted into the fitting hole 7 of the external wall 6. The connecting projection 11 of the earthquake-resisting wall 10 is connected to the steel column 2 from the outside of the earthquake-resisting wall 10, and the lower part of the earthquake-resisting wall 10 is connected to the foundation side.
