The invention relates to a construction method for a high-rise
reinforced concrete elevator shaft. The construction method comprises the steps: step one, a movable platform is assembled; step two, the movable platform is lifted and installed in position by using a
tower crane after completing construction of a first floor
elevator shaft; step three, the movable platform which is lifted and installed in position is arranged in a tilted mode, a
scaffold is vertically fixedly arranged on the tilted movable platform, an overturning lap beam is arranged on the wall of the
elevator shaft in a
lap joint mode, and the overturning lap beam is clamped by a limiting clamping plate; step four, the
scaffold is fixed firmly; step five, a formwork of the elevator shaft is installed, and the formwork is erected on a horizontal-bar-positional continuous wood beam of the shaft wall; step six, concrete construction is carried out on the elevator shaft; step seven, the formwork of the elevator shaft is removed; step eight, the movable platform is installed in position; step nine, repeating the step four to eight until the construction of the high-rise
reinforced concrete elevator shaft is completed. According to the construction method for the high-rise
reinforced concrete elevator shaft, the construction method can be utilized repeatedly, the usage of the formwork is effectively reduced, the manpower input is lowered, the cross-operation of a formwork worker and a
scaffolder is reduced, and the project cost is lowered.
