摘要：蒸压加气混凝土与岩棉复合的围护墙板是一种新型的建筑围护结构板材，不需要附加保温层就可满足寒冷地区的热工要求。GB 50176—2016《民用建筑热工设计规范》就如何计算围护墙板的热工参数给出了计算方法，但需要相邻部分热阻比值不大于1.5，当热阻比值大于1.5时需要通过传热有限元计算考虑热桥的影响，给传热系数计算带来困难。基于此，提出了一种传热系数的简化计算方法，借助线性变截面的热传导公式，考虑了复合板肋部热桥影响，以综合传热系数最大为条件，得到了综合传热系数和综合热阻。利用所提出的计算方法对某工程外围护墙板进行了传热系数计算，并与有限元计算结果进行了对比，相差仅0.3%，可以满足工程设计要求。 Abstract: The integrated lightweight composite wallboard made of autoclaved aerated concrete and rock wool panel is a new type of building enclosure system, which can meet the thermal requirements of cold areas in China without additional insulation. GB 50176—2016 The Code for Thermal Design of Civil Buildings gives a thermal calculation method, which requires the thermal resistance ratio of adjacent parts to be less than 1.5, or else it needs to consider the influence of heat bridge by heat transfer finite element calculation. The finite element method brings difficulties to thermal design. Therefore a heat transfer calculation method based on the linear variable cross-section considering the thermal bridge effect of the composite ribs is put forward, and the heat transfer coefficient and thermal resistance of the wallboard are obtained under the condition of maximum heat transfer. The heat transfer coefficient of the composite wallboard is calculated using the method in this paper, and the results are compared with the finite element calculation method, the difference is only 0.3%, which can meet the engineering design requirements.

Abstract: The integrated lightweight composite wallboard made of autoclaved aerated concrete and rock wool panel is a new type of building enclosure system, which can meet the thermal requirements of cold areas in China without additional insulation. GB 50176—2016 The Code for Thermal Design of Civil Buildings gives a thermal calculation method, which requires the thermal resistance ratio of adjacent parts to be less than 1.5, or else it needs to consider the influence of heat bridge by heat transfer finite element calculation. The finite element method brings difficulties to thermal design. Therefore a heat transfer calculation method based on the linear variable cross-section considering the thermal bridge effect of the composite ribs is put forward, and the heat transfer coefficient and thermal resistance of the wallboard are obtained under the condition of maximum heat transfer. The heat transfer coefficient of the composite wallboard is calculated using the method in this paper, and the results are compared with the finite element calculation method, the difference is only 0.3%, which can meet the engineering design requirements.
