초록

본 연구는 최근 고층 건축물의 외장 마감으로 사용되는 커튼월 중, 유니트 커튼월 방식의 양중 문제 해결을 위하여 커튼월의 수직부재인 멀리온을 레일로 활용하고자 하였다. 커튼월 멀리온의 레일 적용에 따른 양중 가능 여부는 Mock-Up Test의 진행을 통해 20m/sec의 풍속에도 양중이 가능한 것으로 나타났으며, 비교를 위해 선정된 현장 기준으로 공사 기간은 약 20% 단축이 가능하며 투입 인원은 약 33%를 줄일 수 있을 것으로 분석되었으며, 10,000㎡의 설치를 가정하면 80% 이상의 시공비용 절감이 가능한 공법으로 판단된다.

This study was to solve the lift problem of the existing unit curtain wall type by using the vertical material mullion as a rail in curtain wall, which is recently used as an external finishing material for high-rise buildings. It has been shown that the application of the curtain wall mullion's rail can be quantified even at 20m/sec wind speed through the Mock-Up test. Based on the sites selected for comparison of construction methods, it was analyzed that the construction period could be shortened by 48 days, or about 20 percent. It was analyzed that the number of construction workers could be reduced by about 33 percent from the previous nine to six. Based on these results, assuming the installation of curtain wall units of 10,000㎡, it is judged that construction cost can be reduced by 80% or more.
