摘要
指出了常规钢结构屋面中,由于钢板对水蒸气的零渗透,致使结构层内各界面形成较高的水蒸气分压力是结构内产生结露的根本原因。研究表明.带通风层钢结构屋面结构内各界面水蒸气分压力较低,具有不易结露、自重轻、隔热效果好、节能和降低初投资等显著优点,具有较高的市场推广价值。
Due to moisture infinite resistance of steel sheet, vapor pressure is high which is natural reason of condensation in familiar steel structure roof. The interracial vapor pressure is rapid attenuation after setting ventilation layer, and it has many advantages such as no condensation, light, good effect of heat insulation, energy saving, invest saving and so on, which makes steel structure roof with ventilation layer have good market prospect.
