Abstract

The purpose of this research is to obtain experimental data for developing a structural design of an external insulation system by evaluating the shear performance of a composite insulation system according to the adhesive type. The shear performance of the composite insulation system was experimentally evaluated by considering a simultaneous placement method, full and spot/edge coverage using adhesive mortar. As a result of the test, the shear strength of simultaneous placement and full coverage method was almost similar, the spot/edge coverage method was about 80% of them. Also, the simultaneous placement method is considered to be constructively advantageous when applied as an external insulation system to a high-rise building compared to using an adhesive mortar.

본 연구의 목적은 부착 유형에 따른 준불연 복합단열판의 전단성능을 평가하여 외단열시스템의 구조설계법을 개발을 위한 기초자료를 확보하고자 한다. 준불연 복합단열판을 콘크리트와 동시 타설한 방법, 접착 모르타르를 활용하여 전면도포방식와 점·테두리 접착방법 등을 적용하여 전단성능을 실험적으로 평가하였다. 전단성능평가 결과, 동시 타설방법과 전면도포방식의 전단내력은 거의 유사하였고 점·테두리 접착방식은 약 80% 정도 수준이었다. 또한, 동시 타설방법은 접착 모르타르를 사용하는 방법에 비하여 외단열 시스템으로 적용할 경우 구조적·시공적으로 유리할 것으로 판단된다.
