PROBLEM TO BE SOLVED: To provide an RC construction column capable of accomplishing the further rationalization and labor saving of construction work by making three stories of a building as one unit, a beam frame, its construction method and a tandem PCa beam unit. SOLUTION: One layer column section and one column-beam joint section are made as one story, in order to construct a column making three stories as one unit composed of the first class (α), the second story (β) and the third story (γ) toward above, a three layer column unit 1 and a shell PCa column member 2 for one layer alternately provided in the direction of the height of a frame, and in order to construct a beam, a tandem PCa beam unit 30 and PCa beam members 4and 5 connected to column-beam joint sections 3a to 3c are included, and the RC construction column and the beam frame are formed by integrating these three layer column unit 1, the shell PCa column member 2 for one layer, the tandem PCa beam unit 30 and the PCa beam members 4 and 5 with cast-in-place concrete.
