为了定量分析热桥位置对墙体热工性能检测结果的影响，试验选择南京地区常用墙体，选用基于控温箱－热流计法原理的检测设备，系统研究了柱、窗等热桥位置对不同测点的墙体热工性能检测结果的影响规律。结果表明：控温箱－热流计法现场测点选择时，应考虑控温箱与热桥的距离；当控温箱的边缘距离窗220 mm，距离热桥柱大于500 mm时的测试结果基本稳定，可以忽略热桥柱和热桥窗对检测结果的影响。

In order to quantitative analysis the effects of thermal bridge location on thermal performance of external wall,a commonly wall from Nanjing was chosen,and an experimental study about the effects of thermal bridge location such as column and window on the thermal performance of external wall was conducted by means of the measurement of temperature controlled box-heat flow meter. The results showed that the distance of the box and thermal bridge in-situ inspection should be consider when choosing the measuring spots;when the distance of the window and the edge of the temperature controlling box is 220 mm,and the distance of the thermal bridge column is greater than 500 mm,test results are basically stable, the influence of the thermal bridge column and window on the test results can be ignored.
