摘要
某超高层双塔楼核心筒采用混凝土劲性结构,外围采用巨型劲性柱加伸臂桁架结构,楼板为钢筋桁架模板-混凝土组合结构,双塔在标高229.20 m以上为刚接,结构复杂,施工困难。重点介绍了模架支撑、双塔刚接、钢结构吊装、隔振阻尼器的安装等关键技术,为类似工程的施工积累了经验。
The steel reinforced concrete structure is applied to the core tube of one super tall twin towers, with large stiffness column and outrigger on the outside of it. The floor slab is composed of steel bar truss formwork and concrete combined structure. The twin towers are rigidly connected over the elevation of 229.20 m, and the construction is difficult due to its complicated structure. This paper mainly introduces several key technologies including formwork support, rigid connection of twin towers, hoisting of steel structure, and installation of the damping isolator, which accumulate experience for similar engineering construction.
