PROBLEM TO BE SOLVED: To provide an external frame reinforcing construction method which can be installed even in a place having no site and no positional room from the adjacent building and does not block sunshine, can usefully use the site. SOLUTION: A new foundation 2 for an external frame 5 is constructed between columns 47 of the existing building 1 at a position where it does not interfere with the existing foundation 19 and a foundation beam 3 is constructed on the new foundation 2 in site operation, a precast concrete reinforcing column unit 6 is arranged on the foundation beam 3, on the new foundation 2 to tie upwards, the precast concrete reinforcing beam unit 7 is supported at a specified level, the upper and lower reinforcing units 6 are integrated by the vertical PC steel member, the space between the horizontal reinforcing column unit 6 and reinforcing beam unit 7 is integrated by the horizontal PC steel member to construct the external frame 5. The space between the external frame 5 and the existing building 1 is connected by a connection slub so as to transmit a shearing force. COPYRIGHT: (C)2005,JPO&NCIPI
