摘要
采用控温箱-热流计方法测试了3层正交胶合木(CLT)墙体的热阻,分析了不同缝隙宽度(0、2、6 mm)和缝隙数量(0、1、2、3)对CLT墙体热阻的影响。结果表明:3层CLT墙体热阻平均实测值为0.84(m2·K)/W,包含6 mm宽缝隙的CLT墙体热阻值比无缝隙CLT墙体热阻值高23.75%;墙体热阻随着缝隙宽度和缝隙数量增加而增大。
The thermal resistance of 3-ply cross-laminated timber （CLT） wall was measured using the measurement of temperature controlled box-heat flow meter. And the effects of gap width （0,2 and 6mm） and gap number （0,1,2 and 3） on thermal resistance of CLT wall were analyzed also in this study. The resuhs showed that the average value of the thermal resistance of 3-ply CLT wall is 0.84 （m2·K）/W. The thermal resistance of CLT wall specimen wit/2 6mm-wide gaps was 23.75% higher than that of CLT wall specimen without gap. And the thermal resistance of 3-ply CLT .wall increased with the increasing of gap width and gap number.
