摘要
木质建筑结构相较于其他结构建筑而言,其荷载承受能力较差,为此,以提升装配式轻型木结构工程质量为目的,研究了考虑装饰特性的装配式轻型木结构施工技术优化方法。将装配式轻型木结构施工技术划分为部品设计、地基开挖、墙体制作安装、楼盖施工等流程。从图形、外观、物理与热量4个方面分析装配式轻型木结构装饰特性;基于装饰特性,构建轻型木结构部品BIM模型。基于部品BIM模型,通过部品部件分类和编码、BIM模型信息定义与扩展、BIM模型入库管理等环节生成BIM模型库。基于BIM模型库,利用模数化网格构建方式对墙体、楼盖等进行功能布局,通过与所构建的部品BIM模型库配套的装配式建筑构建方法,完成轻型木结构变型设计,以此优化装配式轻型木结构施工技术。实例分析结果表明,该方法可提升装配式轻型木结构连接点的能耗性能,提升建筑整体的荷载承受能力与抗震能力。
Compared with other structural buildings,the load bearing capacity of wooden building structure is poor.For this reason,with the purpose of improving the quality of the fabricated light wooden structure project, Optimization method of the construction technology of the fabricated light wooden structure considering the decorative characteristics is studied.The construction technology of prefabricated light wood structure is divided into parts design,foundation excavation,wall production and installation,floor construction and other processes.From the four aspects of graphics,appearance,physics and heat analysis,the decorative characteristics of the fabricated light wood structure are analyzed;based on the decorative characteristics,a BIM model of the light wood structure parts is constructed. Based on the part BIM model,the BIM model library is generated through parts and components classification and coding,BIM model information definition and expansion,and BIM model warehousing management. Based on the BIM model library,the modular grid construction method is used to carry out the functional layout of walls,floors,etc,and the light wood structure variant design is completed by the construction method of the assembled building matching the BIM model library of the constructed parts,so as to optimize construction technology of fabricated light wood structure.The results of the case analysis show that the method can improve the energy consumption performance of the connection points of the fabricated light wood structure,and improve the overall load bearing capacity and earthquake resistance of the building.
