摘　　要：为了消除装配式混凝土结构的安装湿作业,提升建筑节能性能,研发一种适用于村镇低层超低能耗房屋建造的装配式混凝土格栅复合墙体结构,提出经过优化的六边形洞口格栅复合墙体、条形夹芯保温楼板、螺栓连接的企口接缝以及构件间的连接方式。通过对墙构件的数值模拟,研究了格栅复合墙体结构与连接节点的传力特点与破坏模式。为了提高计算效率,提出了一种基于壳单元的格栅复合墙简化模型,该模型将格栅墙体精简为无洞口的匀质壳单元墙体,将螺栓进行非实体简化。通过参数分析发现,格栅墙体六边形洞口采用保温材料填充后,实现了结构自重轻、用材少、经济环保的目的,可满足村镇低层住宅结构的承载力要求,为村镇住宅的建造提供了一种新型结构体系。A prefabricated concrete grid composite wall structure has been developed to address the need for energy-efficient and easy-to-install construction methods for low-rise ultra-low-energy houses in villages and towns.The optimized hexagonal opening grid composite wall,strip sandwich insulation floor,bolted rabbet joints,and connection modes between components are proposed.Through numerical simulation of wall components,the force transfer characteristics and failure modes of the grid composite wall structure and connection joints are studied.In order to improve computational efficiency,a simplified model of the grid composite wall based on shell elements is proposed.In the model,the grid wall is simplified into a homogeneous shell element wall without openings,and the bolts are also simplified non substantively.Parameter analysis has shown that filling the hexagonal openings of the grid wall with thermal insulation materials can achieve the objectives of light weight,material efficiency,cost-effectiveness,and environmental friendliness,while also meeting the bearing capacity requirements of low-rise residential structures in villages and towns.The structural system provides a new option for constructing houses in rural areas.
