초록

The purpose of this study is to develop a exterior insulation wall construction method with fire safety. As a first step, domestic and aborad regulations were investigated, and three development factors were drawn: use of a non combustible insulation and a metal fixing material, application of a vertical fire spread prevention structure, and a vertical void block structure. First, dry type and wet type exterior insulation system were developed using the non combustible mineral insulation and the metal "L" type angle, which was adhered on the wall without void. Then a fire performance of the systems was evaluated by ISO 13785-2 large scale fire test. As results, mineral insulation occurred some cracks, but there was none of melting, falling and exfoliation during 25 min. Dry type aluminum panels were almost burned and fallen down, whereas wet type coat finish was only burned out on the face and there was none of falling and exfoliation. The highest temperature value was $755{\sim}891^{\circ}C$ at the upper part after 20 min and $287{\sim}497^{\circ}C$ at the lower part after 7 min. The highest heat flux value was 68 kw/m2 at the right point of bottom part, which was caused by crack of mineral insulation. It is need to study exterior fire test more and accumulate data and establish a fire performance standard by ISO 12785-2.
