建筑湿害是建筑物使用功能的常见病和多发病,应当引起我们重视。由于使用环境湿度过大、给排水管道渗漏及地下毛细水上升,以及由于室内空气湿度较室外高而引起的外墙围护结构两侧存在压力差,使得水分子从墙体一侧通过围护结构向较低的一侧扩散所引起的渗透等原因,都会造成建筑湿害。 Building wet damage is a common and frequently used function of buildings, which should arouse our attention. Due to the use of excessive humidity, water supply and drainage pipe leakage and underground capillary water rise, and due to indoor air humidity is higher than the outside caused by the outer wall of the envelope on both sides of the pressure difference, making the water molecules from the side of the wall through the fence Protective structure to the lower side of the proliferation caused by the infiltration and other reasons, will cause the building wet damage.
