摘　　要：介绍了深圳星河雅宝高科创新园三地块项目超高层塔楼内爬塔吊附着装置方案的优化。原方案中内爬塔吊通过传统形式的牛腿附着在核心筒墙体上,承重梁与牛腿焊接,使得塔吊荷载造成的墙体的面外弯矩较大、墙体钢筋用量较高。同时,由于焊接和切割工作量大,承重梁安装和拆除效率也较低。为解决这一问题,对几个不同附着装置方案进行了对比。通过有限元计算得到了各方案的墙体面外弯矩,并计算了墙体钢筋用量。结果表明,采用销轴连接和滑动牛腿的方案,可以有效地减小墙体的面外弯矩,减少墙体钢筋用量。同时由于省去了焊接和切割工作,安装和拆除承重梁的时间大幅减少,减少了塔吊爬升操作占用的工期。The optimization on the attached device scheme of climbing tower crane in the super high-rise tower of Shenzhen Xinghe Yabao High-tech Innovation Park Plot 3 Project is introduced.In the original plan,the internal climbing tower crane is attached to the core cylinder wall through the traditional corbel,and the bearing beam is welded with the corbel,which makes the outer bending moment of the wall plane caused by the tower crane load larger and the amount of wall reinforcement higher.At the same time,due to the heavy workload of welding and cutting,the installation and removal efficiency of bearing beam is also low.To solve this problem,several different attached device schemes are compared.The outer bending moment of the wall plane of each scheme is obtained through finite element calculation,and the amount of wall reinforcement is calculated.The results show that the outer bending moment of the wall plane can be effectively reduced and the amount of wall reinforcement can be reduced by adopting the scheme of pin connection and sliding corbel.At the same time,because the welding and cutting work are omitted,the time for installing and removing the bearing beam is greatly reduced,and the construction period for tower crane climbing operation is reduced.
