A method of constructing simultaneous constructing-type prefabricated stairs by using PC forms is provided to speed up the constructing work and minimize the installation area of the mold without stair inner molds by using the stair wall half PC panel. A method of constructing simultaneous constructing-type prefabricated stairs by using PC forms comprises the steps of: installing a stair wall half PC panel(210) on the lower slab; installing a stair landing PC panel at the center of the stair wall half PC panel; mounting a support rod(350) for supporting the half PC panel; distributing reinforcing bars to the stair wall half PC panel and the stair inlet wall half PC panel; assembling an upper stair PC member between the stair landing PC panel and the half PC panel; installing a stair wall outer mold(230) and a stair inlet wall outer mold(240) and mounting an upper slab mold(100); pouring and hardening the unset concrete; and removing the upper slab mold, the stair wall outer mold, the stair inlet wall outer mold, and the support rod. |
