大型体育馆屋盖钢结构累积滑移+散拼施工技术

Construction Technology of Accumulated Sliding and Assembling Separately for Steel Structure of Large Stadium Roof

以东安湖体育公园三馆项目多功能体育馆屋盖钢结构施工为例,介绍双向正交桁架结构累积滑移+散拼施工技术,解决大跨度屋盖钢结构采用整体提升或散拼安装方式占用场馆场地,造成施工场地使用效率低的问题,此方法实现屋盖钢结构同下部预制看台板结构专业的交叉施工,缩短整体施工工期。

Taking the steel structure construction of the multi-functional stadium roof of Dongan Lake Sports Park Third Hall project as an example,this paper introduces the construction technology of twoway orthogonal truss structure cumulative sliding+assembly,which solves the problem that the large-span roof steel structure uses integral lifting or assembly to occupy the site,resulting in low use efficiency of the construction site.This method realizes the professional cross construction of the roof steel structure and the lower prefabricated observation board structure,and speeds up the overall construction period.
