PURPOSE: A vertical jacking method of a steel mold form using a kicker block is provided to reduce the building time of mold forms, to improve work precision, to decrease a term of works, and to save construction costs. CONSTITUTION: First, concrete is cast into a mold form of a kicker block(2) after installing the kicker block on the bottom side of concrete for forming a wall. Second, a retaining wall reinforcing bars(4) are planted in a forming part of the wall, and extra reinforcing bars are arranged. Third, a steel wall mold form(6) is fixed on the kicker block on both sides of the arranged retaining wall reinforcing bars. Fourth, the mold form of the kicker block(8) is installed on the upper end part of the wall mold form. Fifth, concrete is cast into the wall mold form and the kicker block mold form. Sixth, concrete is cured during a certain period. Seventh, retaining wall reinforcing bars and extra reinforcing bars of the next upper story are arranged on the cured wall concrete. Eighth, the wall mold form is separated from the wall concrete and dismantled from the assembled state. Ninth, the dismantled wall mold form is vertically lifted by a crane and assembled to a kicker block(2a). Tenth, a slab mold form is installed.
