福州海峡奥体中心体育馆四边形环索弦支-张弦组合结构施工技术

Construction Technology of Quadrilateral Strops Suspension-string Composite Structures in the Strait Olympic Sports Center Gymnasium of Fuzhou

福州海峡奥林匹克体育中心体育馆屋盖采用四边形环索弦支-张弦组合结构,其预应力施工难度极大。分别从拉索张拉顺序和张拉力的施工仿真计算、节点形式设计、钢结构安装流程、张拉工装设计、拉索安装方法、预应力张拉流程以及施工监控量测等方面,详细论述了四边形环索弦支-张弦预应力组合结构的施工技术和特点。

Quadrilateral strops suspension-string composite structures is adopted in Strait Olympic Sports Center Gymnasium of Fuzhou,with a certain degree of difficulty of prestressing construction. In this paper,quadrilateral strops suspension-string prestressed composite structure construction technology and features are discussed in detail,respectively from the construction simulation calculation of cable tension order and tension,joints form design,steel structure installation process,tensioning tooling design,cable installation methods,processes of prestressed tension and construction monitoring and measurement.
