摘要
南昌东站高架层候车厅外侧28个幕墙铝板开花柱造型,是南昌东站标志性建筑造型结构,全部由双曲异型铝板拼接组合而成,加工及施工难度高.针对该结构造型的龙骨、饰面及细部做法进行详细拆解剖析,通过全流程要点控制,最终实现高品质的外观效果.该工程在既有BIM技术支持下,充分挖掘提升联合下单潜力,有效指导双曲铝板加工、安装,以实现设计效果.同时,通过预焊接、装配式等措施方法,显著提升标准化模块复制施工效率,并保障施工效果整齐划一.预组装龙骨、插接离缝式铝板插接工艺、全异型石材柱脚等工艺做法均可为类似工程提供参考.
Abstract
The 28 aluminum floral columns adorning the curtain wall outside the elevated waiting hall at Nanchangdong Railway Station stand out as the station's iconic architectural feature.These structures are crafted using double-curved special-shaped aluminum panels,posing challenges in assembly and construction.A comprehensive breakdown and analysis of the joist,cladding,and detailed construction techniques have been conducted and a high-quality aesthetic outcome has been achieved by controlling key aspects throughout the process.Leveraging the current BIM technology,the project fully harnessed and enhanced the potential of joint ordering,offering effective guidance for machining and installing the double-curved aluminum panels to achieve the design effect.Furthermore,pre-welding,prefabrication,and other methods notably boosted the construction efficiency of standardized module replication,ensuring a consistent and uniform construction effect.Technological practices like pre-assembled joists,the splicing process of open-joint aluminum panels,and fully special-shaped stone column bases offer valuable insights for similar projects.
