摘要:
装配式预制构件优化设计是建筑产品节能、环保、全生命周期价值最大化的基础. 为使装配式轻质隔墙板在满足力学性能、保温隔热性能、预制简单等条件下获得最优结构,对新型装配式轻质隔墙板进行了数值分析及优化设计. 以标准化隔墙板为基础,将圆形孔洞调整为椭圆形孔洞,通过数值分析比较了两种隔墙板(圆形截面和椭圆形截面)的受力性能和保温隔热性能. 力学性能主要考虑了施工和使用过程可能出现的荷载模式,对隔墙板的整体刚度和薄弱点的应力集中效应进行了分析;保温性能分析则通过设定热参数,比较了这2种隔墙板在密闭空间内的降温时间. 数值分析结果表明,采用椭圆孔隔墙板不仅自重减少5.6%,孔洞应力集中效应也有一定程度的减小,其保温性能比圆孔隔墙板提升了12%.
Abstract:
The optimum design of the prefabricated components is the foundation of energy saving, environmental protection and maximum life of building products. In this paper, the numerical analysis and optimum design of a new type of lightweight partition board are carried out to meet the requirements of mechanical properties, thermal transferring and simple prefabrication. Based on the standard partition board and numerical analysis, the circular cross section type partition board is modified to elliptical cross section type. The numerical analysis is carried out to compare two types of partition plate (circular and elliptical cross section) with respect to the mechanical performance and heat transfer performance. Among them, load modes which may occur in construction and service stage, are used to study the mechanical properties, effect of stress concentration and overall partition board stiffness. And the heat transfer performance analysis is also carried out to compare the cooling time for the two kinds of partition boards in the confined space. The numerical analysis results show that the elliptical partition board not only reduces its weight by 5.6%, but also reduces the stress concentration effect of the hole to a certain extent. Besides, the thermal transferring performance of the elliptical partition board is 12% higher than that of the circular partition wall plate.
