초록

본 논문은 단열갱폼의 공동주택현장 적용을 통해 단열갱폼 동절기 보양우수성을 확인하고, 현장 적용에 따른 경제적 타당성을 분석하고 있다. 실험결과에 따르면 실제 보양투입 비용은 사전계획대비 약 5천 2백만 원을 절감하였으며, 기존 일반갱폼대비 약 1억 6천만 원을 절감하였다.(참고 - 변경전 갱폼 자재비는 2억 6천만 원에서 변경 후 3억 1천만 원으로 약 5천만 원 증가함) 결과적으로 단열갱폼으로 변경하여 약 1.1억 원 가량의 공사비를 절감할 수 있었다. 현장마다 층수, 동수, 면적이 달라짐에 따라 보양공사비가 변경될 수 있으니 단열갱폼 적용 예정인 현장에서는 사전에 충분한 검토가 이루어져야 할 것으로 판단된다.

This paper verifies the superiority of warming work in winter by applying the insulation gang-form to the apartment housing site and analyzes the economic feasibility of the application. According to the experimental results, the actual cost of warming work was about 52 million won less than planned, and 160 million won less than the existing average.(Note - The cost of gang form material increased from 260 million won to 310 million won after the change) As a result, the construction cost could be reduced by about 110 million won. As the costs of warming work can change depending on the number of floors, the building number, and the area of each site, it is deemed necessary to conduct a thorough review in advance at the site where the cost of warming work is to be applied.
