타설형 콘크리트 중단열 벽체의 요구성능 분석

Energy load of building affected by insulation performance of building's exterior. and insulation system can be classify interior insulation, exterior insulation, sandwich insulation according to install place of insulation. but within interior insulation system, corner wall and the cross outer wall-slab insulation part may occur thermal bridges. And then, within exterior insulation system is more superior insulation performance than interior insulation, but it has difficult to apply, easily broken at high building because of strong wind load. And also difficult to maintenance exterior insulation system. So, in this study, to found requirement performance of cast-in-place sandwich insulation system that is superior insulation performance and easy construction and maintenance. requirement performance of cast-in-place sandwich insulation system is 1) To avoid thermal bridges in the insulation performance, 2) Both sides concrete wall can be composite action in the structural performance. Because of this study, can develops cast-in-place sandwich insulation system and this insulation system contribute to improve insulation performance of apartment-house and high building.
