A construction method of PC stairs is provided to minimize the interference between a wall reinforcing bar and an anchor bar embedded in a PC member when carrying a PC member in a staircase, to exclude the formation of a coupling hole in a wall, and to secure a working passage of a worker easily. A construction method of PC stairs comprises the steps of arranging a wall reinforcing bar(10), constructing an outer form(20) facing the outside of a staircase and constructing a lower form(30) to form a wall of a staircase, installing a temporary support(40) for supporting PC stair landing(50) to the inside of the staircase, installing PC stair landing and a PC swash plate(60), and coupling a connector to the side of the PC stair landing to make the PC stair landing support a wall, constructing an upper form(32) forming a portion of an inner form, and placing wall concrete(80) between the outer form and the inner form. |
