摘   要：为了验证采用模拟计算的方法研究金属连接件对保温与结构一体化墙体热工性能影响的准确性与可靠性，首先依据(GB/T 13475—2008)《 绝热稳态传热性质的测定标定和防护热箱法》规定的防护热箱法，制作实验墙体，并在实验台上分别对锚入金属连接件数量为 3 、6 和 9 个的保温与结构一体化墙体进行了实验研究 ，获取了墙体的实测传热系数 。随后利用Airpak 计算流体力学软件建立与实验研究相同的三组模型 ，并设置了相同的热室与冷室温度工况 ，分别计算其传热系数 。最后对实测结果与模拟结果进行了对比 。结果表明：锚入金属连接件数量为 3 、6 和 9 个时的保温与结构一体化墙体平均相对误差分别为 4. 92% 、4. 69%和 3 . 96% ,  模拟计算误差均在 5%范围内，满足工程计算要求。

Abstract：In order to verify the accuracy and reliability of using the method of simulation calculation to study the influence of metal connectors on the thermal performance of thermal insulation and structural integration wall, the experimental wall is first made according to the protective hot box method stipulated in "Determination and Calibration of Thermal Insulation Steady State Heat Transfer Properties and Protective hot box Method" (GB/T13475-2008). Experimental study was carried out on three, six and nine insulation and structural integration walls with anchored metal connectors on the experimental platform, and the measured heat transfer coefficients of the walls are obtained.Then Airpak computational fluid dynamics software is used to establish the same three groups of models as the experimental study, and set the same hot chamber and cold chamber temperature conditions, respectively, to calculate their heat transfer coefficients.Finally, the measured results are compared with the simulated ones.The results show that the average relative errors of insulation and structural integration wall are 4.92%, 4.69% and 3.96% respectively when the number of anchored metal connectors is 3, 6 and 9, and the simulation errors are all within 5%, which meet the requirements of engineering calculation.
