摘要
装配式钢结构施工速度快、应用场景广的特性,在特殊造型要求的公共建筑项目中多有应用。而相较于传统框架钢结构形式,大跨度悬挑装配式钢结构在施工过程中则需结合其施工过程中各阶段结构受力变化特性细化施工方案。本文以厦门某公共建筑装配式钢结构为例,通过分析该项目的施工过程重难点,对地下室、地上两阶段的吊装顺序及临时支撑设置控制要点进行了阐述,最后探究BIM技术在大跨度悬挑装配式钢结构施工的具体应用,以期为此后类似工程提供参考。
The characteristics of fast construction speed and wide application scenarios of prefabricated steel structures are widely used in public building projects with special shape requirements.Compared to traditional frame steel structures,large-span cantilever prefabricated steel structures need to refine the construction plan during the construction process,taking into account the structural stress changes at each stage of the construction process.This article takes the prefabricated steel structure of a public building in Xiamen as an example,analyzes the key and difficult points of the construction process of the project,elaborates on the lifting sequence and temporary support setting control points of the basement and above ground stages,and finally explores the specific application of BIM technology in the construction of large-span cantilever prefabricated steel structures,in order to provide reference for similar projects in the future.
