초록

2017년 6월 30일 국토교통부는 주차단위구획의 최소 크기를 확대하는 것을 입법 예고하였다. 주차단위구획의 확대는 주차장 연면적의 증가를 초래하여 아파트 분양가를 상승시킬 우려가 있다. 그러므로 주차장의 기둥 간격과 개수를 조정하고, 주차효율이 좋은 8-Bay 장스팬 주차모듈을 적용할 필요가 있다. 연구결과, 주차단위구획을 확대한 6-Bay 주차모듈과 8-Bay 주차모듈의 공사비는 거의 비슷한 수준이었으나, 8-Bay 주차모듈의 연면적 감소 효과가 확인되어 8-Bay 주차모듈이 더 경제적인 것으로 나타났다. 8-Bay 주차모듈의 공사비를 분석한 결과, 탈형데크플레이트 RC공법을 적용한 모듈이 가장 경제성이 있는 것으로 나타났다. PC 복합화공법은 부재의 체적 증가로 인해 비교적 공사비가 높게 나타났으나, 프리스트레스를 적용하여 보 춤을 감소시키면 경제성을 확보할 수 있을 것으로 확인되었다. 또한 중공슬래브 공법 모듈은 가장 공사비가 높게 나타났으나, $1m^2$당 공사비가 가장 낮아 비용적 측면에서 아파트 주차장의 구조공법으로 적용 가능성을 확인하였다. 이 연구는 8-Bay 주차모듈의 공사비를 분석하고 비용적 측면에서 경제성을 확인하였다는 점에서 의의를 가지며, 향후에 8-Bay 주차모듈을 적용한 최적의 공법을 도출하는데 기초자료로 활용될 것으로 기대된다.

On 30 June, 2017, the Ministry of Land, Infrastructure, and Transport announced the minimum size of parking section will be expanded in parking lots. The expansion of parking section could lead to increase in apartment prices because of increase in total area of the parking lots. It is necessary to adjust the column spacing and number in the parking lots and to apply the 8-Bay long-span parking module with good parking efficiency. According to the study, the construction cost of the 6-Bay module and 8-Bay module was almost the same. But The 8-Bay module was more economical than the 6-Bay module because of the reduction in total area of 8-Bay multi-moduel. The Result of construction cost of 8-Bay modules, Removal Deck-plate RC system was most economical. While the construction cost of PC system was higher due to increase in volume of the member, it would ensure sufficient economy by reducing the girder height to apply a pre-stress method. Also, the construction cost of hollow slab system was the highest. But it could be used as the underground parking lots for apartment, because it had the lowest cost per square meter. This Study has a academic significance by proving the applicability of the 8-Bay Module to underground parking lot of apartment. And it is expected that this study will be used as basic data to derive optimal construction method that applies 8-Bay Module.
