摘　　要：本文基于螺栓连接装配式墙板体系,以西藏某地区环境特点为前提,采用有限元模拟方法,对不同构造的墙板热工性能进行分析,结果表明,螺栓连接节点部位实心混凝土构造的热桥效应最为明显,其次为穿过夹心保温层的拉筋,该部分的热桥不可忽视;增设100mm厚岩棉保温板,可解决上述热损失,并可满足超低能耗标准。Based on the bolted prefabricated wall panel system and the environmental characteristics of a certain area in Xizang,this paper uses finite element simulation method to analyze the thermal performance of different structures of wall panels.The results show that the thermal bridge effect is the most obvious at the bolted joints of solid concrete structure,followed by the tensile reinforcement passing through the sandwich insulation layer,where the thermal bridge in this section can not be ignored.The addition of 100mm thick rock wool insulation board.
