Abstract

To figure out the problems of flame retardant treatment (FRT) on wooden buildings, field investigation and analysis of statistical data are performed. After FRT on historical wooden building, efflorescence and exfoliation showed most often. These problems appeared especially on column, rafter and Ga-gu (Ingredients for supporting structure of a roof) which are liberally spreaded. To compare before and after FRT, analyzed 20 elements using P-XRF. In this process, found sulfur which informs FRT. This helped set up nondestructive assay. Through this process, confirmed field application by analysis residue component of Songgwang-sa Temple.

방염제 도포 후 나타나는 목조건축물의 문제점을 파악하기 위해 통계자료 분석 및 현장조사를 수행하였다. 방염제 도포 후 백화현상과 단청 박락현상이 목조건축물에서 가장 빈번히 나타났다. 이러한 문제점은 기둥, 연목, 가구부재 등 방염제의 도포가 상대적으로 많이 이루어지는 건축물의 상부에서 가장 높게 나타났다. 현장에서 방염제를 도포한 건물과 도포하지 않은 건물을 파악하기 위해 P-XRF를 이용하여 총 20개 종의 원소를 분석하였다. 이 중 현장의 모든 방염제 처리구에서 황 원소(S)가 나타났기 때문에 이를 방염제 도포의 탐지자로 설정하였다. 이를 통해 현장에서 방염제의 도포를 확인할 수 있는 비파괴분석을 방법을 정립할 수 있었다. 실제 송광사(전남 순천)의 목조건축물을 대상으로 한 잔류성분분석을 통해 실제 현장적용이 가능함을 확인하였다.
