Abstract

Unlike reinforced concrete(RC) construction, the primary determinant of construction schedule for precast concrete(PC) apartment buildings is the lifting equipment. To establish a dry process-centric construction schedule, this study analyzes the lifting unit process for core, internal, and external PC wall components, which differ from traditional PC components. By examining the assembly process of these wall types, the study aims to determine the construction cycle for a standard floor frame of a PC apartment building. The findings will serve as foundational data for developing construction schedules for PC apartment buildings utilizing PC walls.

PC공동주택은 RC공사와 달리 양중장비에 의한 작업이 주공정으로 공기가 산정되기 때문에 PC벽체를 포함한 양중 단위공정분석이 선행되어야 한다. 본 연구는 Core, 내부, 외부 PC벽체의 조립공정을 분석하여 PC공동주택 기준층 공사 Cycle 분석하는 것이다. 각 PC벽체의 양중과정 및 시간을 도출하였고, 그 결과를 사례에 적용하여 기준층 골조공사의 양중 사이클을 분석하였다. 순수 부재설치 기간은 5일로 분석되었고, PC부재별 작업시간 비중은 Core PC벽체는 약 16%, 내부 PC벽체는 약 8%, 외부 PC벽체는 약 18%로 분석되었다. 본 연구의 결과는 PC벽체가 적용된 PC공동주택 골조공사 시공계획 시, 핵심자료로 활용될 것이다.
