초록

외단열시스템에서 준불연 성능을 확보한 부착식 탄산칼슘계 복합단열판은 효과적인 단열성능과 화재안전성을 강화한 것으로, 본 연구에서는 준불연 복합단열판을 대상으로 부착식 준불연 외단열시스템의 구조설계 기초데이터를 확보하기 위하여 복합단열판 및 구성재의 역학적 시험을 수행하였다. 국내외 시험규격을 참조하여 시험체를 제작하였으며, 인장강도, 압축강도, 굴곡강도, 전단강도를 시험 평가하였다. 시험결과로부터 준불연 복합단열판의 강도특성치를 도출하였고, 현행 KS M ISO 4898에서 제시하는 최소 요구물성을 확보하고 있는 것을 검증하였다. 또한, 본 연구에서 사용한 준불연 외단열시스템은 지속적 중량 하중을 받지 않는 벽체의 외단열시스템으로 사용이 가능한 것을 확인하였다.

The application of an adhesive calcium carbonate-based hybrid insulation board with quasi-combustibility in the external thermal insulation composite system(ETICS) ensures effective thermal performance and fire safety. This study aimed to conduct a mechanical test of the quasi-non-combustible hybrid insulation board as well as its constituent materials to obtain the basic data for the structural design of the adhesive ETICS. Test specimens were fabricated based on domestic and foreign test standards to examine and evaluate their tensile, compressive, flexural, and shear strengths. The strength characteristics of the quasi-non-combustible hybrid insulation board were identified from the test results, which verified that the minimum required physical properties suggested by the current KS M ISO 4898 were met. Furthermore, the quasi-non-combustible ETICS used in this study was found to be suitable for use as an external insulation system for walls unless subjected to continuous gravity load, such as a heavy exterior finish.
