구조재-건축물의 골격(조)을 구성하는 목재 * 목재의 일반적인 성질 &nbsp;① 열전도율이 낮고 절연, 흡음 물질 &nbsp;② 향기나는 휘발성, 아름답고 따뜻한 느낌(심리 치료) &nbsp;③ 함수율 : (결합수+자유수)-자유수=섬유포화점(30%) &nbsp;④ 친환경적이며 생산 및 폐기 비용이 저렴하다. &nbsp;⑤ 색깔 : 변재는 담황색, 흰색에 가깝고, 심재는 짙은 갈색, 붉은색 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 청변은 곰팡이로 구조적 영향은 없고, 전염성도 극히 적다. <img class="txc-image" id="tx_entry_3460" alt="이미지를 클릭하면 원본을 보실 수 있습니다." src="https://t1.daumcdn.net/cafefile/pds36/45_cafe_2007_05_31_09_40_465e1975a45bd" border="0">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
