在南方,室内地面受潮的主要原因是室外气象条件的不良影响和地下水份因毛细管作用上升至地板外表面。门窗设置和间歇通风为了防止室外气象因素对室内地面的不良影响,应该设置能便于调节和开启的门窗,以便进行间歇性通风。在门和窗的上部设置通风小窗,在民居建筑中设置半截腰门和门槛,则可使从室外进入室内的热、湿空气和地面保持有一定距离,让它暂时浮在室内上部,不使它与温度较低的地面立即接触,这对于防止地面受潮有一定的控制作用。
In the south, the main cause of indoor floor dampness is the adverse effects of outdoor weather conditions and the rise of groundwater to the outer surface of the floor due to capillary action. Door and Window Setup and Intermittent Ventilation To prevent the adverse effects of outdoor meteorological factors on the indoor floor, doors and windows that can be easily adjusted and opened should be provided for intermittent ventilation. A small ventilation window is set in the upper part of the door and the window, and a half waist door and a door lintel are installed in the dwelling house, so that the hot and humid air entering the room from the outside can be kept at a certain distance from the ground, so that it temporarily floats in the upper part of the room. It is in immediate contact with the lower temperature ground, which has a certain control over the prevention of moisture on the ground.
