钢筋混凝土簿板屋面架空隔热层以其造价低廉,不需维修之优点,在全国各地尤其在南方酷热地区被广泛采用。 我通过大量的调查和研究,发现隔热效果并不理想。其原因如下:①全国各省的屋面架空板的标准图集对架空板的架空高度均规定为200mm(三皮砖高)。架空高度偏低,不利于架空板下空气层形成气流。②很多建筑在屋面四周设计了女儿墙或较高的檐沟板,挡住了隔热板下的空气流动,影响了隔热效果。 The overhead insulation layer of reinforced concrete book panels is widely used throughout the country, especially in the hot regions of the South, because of its low cost and no need for maintenance. I have found through a lot of investigation and research that the insulation effect is not ideal. The reasons are as follows: 1 The standard atlas of roof panels in all provinces of the country is provided with an overhead height of 200 mm (three brick heights). The low overhead height is not conducive to the air flow formed by the air layer under the aerial board. 2 Many buildings have designed a parapet wall or a tall sulcus board around the roof to block the air flow under the insulation board and affect the insulation effect.
