In the first procedure, while the column connection portion 6 of a PCa horizontal structure 7 is arranged on a downstairs PCa column 3, the grout 10 is injected into column sleeves 26 of the downstairs PCa column. In the second procedure, the grout in a predetermined amount is injected into the lower joint 21 and through holes 29. In the third procedure, before hardening of the injected grout, column connection reinforcements 28 for an upstairs PCa column are inserted into the respective column sleeves 26 formed in the lower-story PCa column 3, and the upper-story and downstairs PCa columns are vertically arranged at the beam-column connection portion 8 via the column connection portion.
