摘要

According to the present invention, to install a precast concrete (PC) beam (300) in an upper column (100) which is vertically installed by lifting the PC beam, a column steel frame (130) of which a column lower plate (160) is bonded to a lower end is installed on a lower end of column concrete (110) of the upper column (100). Moreover, a column bracket (140) is installed on a side surface of the column steel frame (130), and a connection plate (150) is installed in the column bracket (140).
