PURPOSE: A continuation method for a core wall for installing post-assembling precast concrete stairs is provided to promote the unification and continuation of a core wall, to shorten a period of construction and to reduce the construction expenses. CONSTITUTION: The continuation method for a core wall for installing post-assembling precast concrete stairs comprises the steps of: pulling up a system form provided with a projected plate upward from the existing floor(n-1), then setting on a spot where a footpace and a halfpace of precast concrete stairs are fixed to construct a core wall of a new floor(n); installing a temporary ladder to install a slab form of an upper floor of the new floor(n-1) and to arrange reinforcing bars; arranging wall reinforcing bars for the new floor(n), fixing many couplers to the outside of the system form to fix the footpace and the halfpace of the precast concrete stairs, then installing a core outer wall form for the new floor(n), installing a slab form for a floor, then arranging slab reinforcing bars; placing and curing concrete to form a wall for the new floor(n) and a slab for the floor, then stripping a core outer form for the new floor(n) and the slab form for the floor(n+1); after removing a temporary ladder using a tower crane, stripping the system form, then pulling up from the new floor(n) to the floor(n+1).
