摘 要:对四块预制混凝土夹心墙板的热工性能进行了试验研究,通过改变拉结件的种类,探索其对墙板热工性能的影响,并采用有限元软件对其进行了模拟分析。结果表明:金属拉结件的热桥效应明显,与无拉结件的预制墙板相比,采用纤维拉结件的墙板的传热系数提高8%,而采用不同金属拉结件的墙板分别提高20.9%与14.3%;建议在实际工程应用中,对墙板的传热系数进行相应的放大,单位面积墙板的放大系数范围为0.71%~2.52%。Abstract: The thermal performance of four prefabricated concrete sandwich wall panels were tested, the effects of the shear connectors on the thermal performance of the wall panels were explored by changing the types of connectors, and the simulation analysis of the performance of these wall panels was carried out by using the finite element software. The results show that the thermal bridge effect caused by shear connectors is obviously. Compared with the wall panel without connectors, the heat transfer coefficient of the wall panel with fiber connectors is increased by 8%, while the heat transfer coefficient of the wall panels with different metal connectors are increased by 20.9% and 14.3%, respectively. It is suggested that the relevant thermal performance parameters of the sandwich panels should be enlarged accordingly in practical engineering applications, and the amplification factor of per unit area should be taken from 0.71% to 2.25%.
