외단열 동시타설 공법에서 단열재 부착강도에 관한 연구

Abstract

In Korea, there have been recently many studies to overcome weaknesses of exterior insulation in terms of workability and safety at high-rise building. And, the exterior insulation board in cast-in-place concrete form system was developed such as permanent insulation form system or integrated system for exterior insulation and wall. We utilized modified method for KS F 2762 to obtain test result for insulation bond strength in this study. Based on this method, we had measurements of bond strength for 12 cases and analyzed the result value of insulation bond strength test. In result, bond strength of EPS(expanded poly styrene, ‘B’ company) in E/F case is nearly 0.08 N/mm2(reference value of EOTA). Considering strong wind load by typhoon in Korea, it is necessary to use connection elements or to improve the bond strength of insulation by ribbed surface.
