高层双塔楼建筑型钢混凝土组合结构施工技术

Construction Technology of Composite Structure of Steel Reinforced Concrete for Double-Tower High-Rise Building

世博动迁户上海振华港机工业研发大楼的结构为型钢混凝土组合框架柱,大跨度后张法有粘结预应力楼盖框架梁,密肋梁空心楼盖。施工中300t钢连廊需整体提升,施工难度大。通过在钢结构施工中采取合理的施工技术与措施,保证了工程优质高效按期竣工。

Shanghai Zhenhua Port Machinery Industrial RD Building combines the steel reinforced concrete frame columns,the long-span post-tensioned and bonded prestressed floor frame beams,ribbed hollow floor beams and the whole lifting of 300-ton steel corridor,and is extremely difficult to be constructed.Delicacy management and reasonable construction technology and measures were taken to ensure the construction quality and efficiency.
