深圳宝安国际机场卫星厅仿清水混凝土异形预应力斜柱施工技术
摘要：深圳宝安国际机场卫星厅工程屋盖支撑柱采用预应力斜柱，且施工质量要求高。通过运用预应力斜柱施工工艺解决异形变截面斜柱的施工难题，形成完整的仿清水混凝土异形预应力斜柱施工技术，总结采用BIM技术放样、钢筋及预应力筋施工、模板与支撑施工、柱顶埋件施工、混凝土施工以及预应力张拉与封锚施工等技术措施，在应用过程中获得理想的效果。

Construction Technology of Prestressed Inclined Column Imitation of Fair-faced Concrete of Shenzhen Bao'an International Airport
Abstract: Prestressed inclined column is adopted in the roof support column of the satellite hall of Shenzhen Bao'an International Airport,which requires high construction quality. Through exploring the prestressed inclined column technology and further solving the construction problems of special-shaped variable cross-section inclined column,a comprehensive inclined column construction technology of special-shaped prestressed imitative fair-faced concrete was formed,such techniques and technologies as the BIM technology lofting,reinforcement and prestressed reinforcement construction,formwork and support construction,construction of embedded parts of column top,concrete construction,prestressed tension and anchor sealing construction,etc. were summarized,achieving desirable effect in the process of construction application.
Keywords: airports; satellite hall; roofs; supports; prestressed inclined column; concrete
