摘　　要：根据蒸汽渗透理论对两种不同构造形式的腹板开孔轻钢龙骨复合墙体进行了传湿分析.结果表明:远离龙骨处的保温层冷侧更易结露,且该处的保温层采暖期重量湿度增量值较龙骨附近的大.墙体2的构造形式比墙体1的构造形式防潮效果好,墙体1须设防潮层才能满足墙体保温与防潮等热工性能要求.Based on the theory of moisture permeation, moisture transfer of the slotted light steel - framed composite wall is analyzed. The results show that the condensation of moisture is easily occurred in the insulation layer far away from the steel - framed component and its moisture accumulation is also more than that of other places. From the point of moisture-proof view,wall 2 with polystyrene board is better than that of wall 1 with rock wool. The layer of moisture-proof must be placed in wall 1 to meet thermal performances of wall.
