Abstract

Recently, floor impact sound has become a serious social problem in Korea. There is an increasing need to improve floor impact sound performance using floor covering installed on the floor of apartment houses. KS F ISO 717-2 and KS F 2863 require measurement under conditions in which the resilient material is not installed. But most apartment houses in Korea install resilient materials to reduce floor imapct sound. The performance evaluation method of floor covering should provide reduced performance for use by residents of apartment houses with resilient materials. Therefore, this paper proposes a reduction performance evaluation under the conditions in which a resilient material is installed to verify the performance of floor covering.

최근 바닥충격음 사후 성능검사 제도의 시행에 따라 공동주택 바닥 슬래브 상부에 설치되는 바닥 마감재에 대한 바닥충격음 성능 개선의 요구사항은 증가하고 있다. 하지만 현재의 KS F ISO 717-2 및 KS F 2863에서의 바닥 마감재 성능 평가방법은 완충층이 설치되지 않은 조건에서 저감량을 측정하는 것으로 되어 있다. 준공 전 성능측정 의무화로 인해 본인이 거주하는 공동주택 바닥충격음 성능의 확인이 가능한 상황에서 입주민이 거주하는 공동주택의 특성을 반영하는 온돌층이 설치된 구조에서의 성능평가는 마감재의 바닥충격음 성능에서 더 필요한 부분일 것이다. 따라서 본 논문에서는 바닥슬래브 상부 마감구조의 저감량 평가를 위해서 완충층 조건을 포함한 저감성능 평가를 제안하고, 완충층 성능에 따른 저감량의 차이를 확인할 수 있도록 마감재가 설치되지 않은 상태의 바닥충격음 성능을 동시에 표시하는 것을 제안한다.
