초록

본 연구에서는 현재 건설신기술로 지정된 복합계방수공법 7개사(A~G)를 대상으로 KS F 2622:멤브레인 방수층 성능평가 시험방법 중 현장 적용조건과 유사성이 큰 평가항목을 선정하여 평가한 결과, 모든 시험체가 기본 물성평가에서 KS 기준을 상회하는 성능을 확보했음에도 불구하고, 내피로(균열 거동) 시험을 제외한 방수성(수밀성) 시험, 처짐 저항성 시험, 부풂 저항성 시험에서 점착 도막 계열로 이루어진 공법의 접합부와 수직부 등 취약부위의 현장품질 성능을 확보하기 어려운 것으로 확인하였다.

In this study, seven companies(A~G) designated as new construction technology selected and evaluated KS F 2622: Method of test for performance evaluation of membrane roofing systems that are similar to field application conditions. As a result of the test, it was confirmed that although all test specimens exceeded KS standards in the basic physical, it was difficult to obtain field quality performance in weak areas such as joints and vertical parts of the adhesive coating method in water-tightness, sagging resistance, swelling resistance tests except for fatigue(crack behavior) tests.
