正放四角锥网架结构在大型钢结构场馆中的设计与施工要点

大跨度空间建筑形式在当下越来越被设计所需要,而网架结构因具有设计灵活、轻巧美观等特点而深受青睐。以安顺娄湖生态湿地公园整体开发PPP项目中的水上艺术中心钢结构场馆屋盖施工为案例,从设计参数、计算分析、工况控制等方面出发,梳理了该工程网架结构形式选择的设计思路与过程。同时,针对正放四角锥网架结构的安装施工,提出了相应的注意事项。所总结的设计与施工技术可以为今后类似项目的大跨度结构设计与施工提供借鉴思路。

Design and Construction Points of Rectangular Square Pyramid Space Truss Structure in Large Steel Structure Venue

At present,the architectural form of large-span space is more and more needed by the design,and the space truss structure is highly appreciated due to its flexible design,light weight and beautiful appearance.Taking the steel structure roof construction of the Aquatic Art Center in the PPP project of the Louhu Ecological Wetland Park in Anshun as an example,starting from the design parameters,calculation analysis,working condition control,etc.,the design ideas and processes of the space truss structure selection is arranged.At the same time,corresponding precautions are put forward for the installation construction of the rectangular square pyramid space truss structure.The summarized design and construction technology can provide reference ideas for the design and construction of large-span structures of similar projects in the future.
