Construction Method of Seismic Retrofit and Seismic Retrofit Structures

摘要

The present invention relates to an earthquake-proof reinforcing structure and an earthquake-proof construction method, which are installed on a building having a lightweight wooden structure and are possible to improve earthquake-proof property. The earthquake-proof reinforcing structure includes: a first bracket including a horizontal part having a shape of coming in contact with a floor surface of a building to be extended and a vertical part connected to the horizontal part and having a shape of coming in contact with a wall surface of the building to be extended; a second bracket including a horizontal part having a shape of coming in contact with a ceiling of the building to be extended and a vertical part connected to the horizontal part and having a shape of coming in contact with the wall surface of the building to be extended; and a connecting support rod having a vertically long shape and vertically connecting the horizontal parts of the first bracket and the second bracket. The earthquake-proof reinforcing structure and the earthquake-proof construction method are possible to prevent collapse of the building while a relative position with respect to the whole floor of the building is fixed thereto.
