The present invention relates to a building construction method using a precast concrete (PC) column with a rigidity reinforcement means disposed on a progressive collapse prevention part in the direction of gravity. The building construction method using a PC column with a rigidity reinforcement means disposed on a progressive collapse prevention part in the direction of gravity comprises: (a) a lower layer PC column forming step of stacking lower layer PC columns which correspond to a height of a building and are positioned below a floor; (b) an upper layer PC column forming step of forming a structure forming a progressive collapse prevention part in the direction of gravity on an upper side of the lower layer PC column separated from the upper side of the lower layer PC column to integrate an upper layer PC column into the lower layer PC column; (c) a step of installing the integrated lower layer PC column and upper layer PC column by lifting at a corresponding construction site, and installing a slab having a spacer disposed on a side of the progressive collapse prevention part in the direction of gravity; (d) a step of installing a rigidity reinforcement means on the side of the progressive collapse prevention part in the direction of gravity in step (c) to expose an end of the rigidity reinforcement means to the outside of outer circumferences of the lower layer PC column and the upper layer PC column to be positioned on the inside of the slab; and (e) a step of depositing and curing concrete on the progressive collapse prevention part in the direction of gravity and a side of the slab. Rigidity of an end side of the slab positioned on the progressive collapse prevention part in the direction of gravity is reinforced, and a crack in a joint of the PC column and the slab is prevented to improve durability. |
