外墙外保温干挂系统典型构造的热桥分析

Analysis onThermal Bridge of Typical Structure of Dry Hanging Exterior Insulation System

对建筑物外墙外保温干挂系统典型构造中存在的"热桥"对系统热工性能的影响进行了分析。通过典型构造中"热桥"对系统传热系数影响的计算比较,指出外墙外保温装饰一体化板材构造中"热桥"所造成的热量损失很小,与示范工程实测数据分析结果相吻合,并提出了降低"热桥"影响的构造措施。

In this paper, we analyzes the effect on the system＇s thermal performance of the ＂thermal bridge＂, which existing in the typical structure of the building exterior insulation dry hanging system. Through the calculation and comparison of the ＂thermal bridge＂ in the typical structure influence on the system＇s heat transfer coefficient, point out that the heat loss caused by the ＂thermal bridge＂ in the integration of exterior insulation decorative plank structure is quite small, which coincide with the analytical results of measured data of demonstration project, also puts forward structural measures to reducing the influence of ＂thermal bridge＂.
