摘　　要：对于装配式建筑来说,其墙板拼接部位通常存在热桥缺陷,是影响其系统整体热工性能的重要因素,进而造成墙体传热量计算出现偏差。本文针对一种新型的轻质装饰结构一体化墙体单元拼接部位的热工性能进行了系统研究,通过截取有效计算单元,以有拼接缝有无隔热填充、不同勾条材质等为基本参数,利用有限元软件Therm进行了二维稳态热工仿真分析,得到了在不同参数条件下的热工性能变化规律,并提出了后续优化设计建议。For prefabricated buildings,there are usually thermal bridge defects in the splicing parts of the wall panels,which is an important factor affecting the overall thermal performance of the system,and then causes the deviation in the calculation of wall heat transfer.In this paper,the thermal performance of the splicing parts of a new type of lightweight decoration-structure integrated wall unit is systematically studied.By intercepting the effective calculation unit,the two-dimensional steady-state thermal simulation analysis is carried out by using the Therm finite element software with or without thermal insulation filling at the splicing joints and different hook materials as the basic parameters,and the variation laws of thermal performance under different parameters are obtained,so that the subsequent optimization design suggestions are put forward.
