Abstract

Recently, the structure system for apartment buildings in Korea has been changing from wall to post-beam structure. This study examines the fire resistance and sound insulation of light-weight dried wall, a component of post-beam structure. For the fire resistance and sound insulation in Korea, the Compartment wall of apartment house in the case of building regulation has regulations specify the detailed requirement of fire compartment walls in apartment, but do not specify that of interior walls. This study proposes the fire resisting rate of the interior wall into three grades in which the highest grade requires fire resistance of 30 minutes and also proposes the requirement of sound insulation performance into three grades in which the lowest grade requires 35dB.

본 연구에서는 국내 공동주택의 건축 형식이 벽식 구조에서 기둥식 구조로 변화하면서 기둥식 구조에서 사용되는 건식 경량벽체에 대한 내화성능과 차음성능 기준을 제시하고자 하였으며, 공동주택 세대간 벽체의 경우는 국내 건축법에서 이미 의무화되어 있는 기준이 있어, 국내에 기준이 없는 세대내 벽체를 대상으로 내화성능은 30분의 내화성능을 1등급으로 하여 3개 성능등급으로 구분하였으며, 차음성능은 Rw+C값이 최소 35dB를 최소등급으로 3개 성능 등급을 기준을 제시하였다.
