马来西亚吉隆坡标志塔的钢连梁施工技术

Construction Technology for Steel Coupling Beam of Kuala Lumpur Landmark Tower in Malaysia

马来西亚吉隆坡标志塔在主楼5~33层的核心筒处采用了钢连梁的设计。该钢连梁通过埋板和锚杆与两侧的墙肢相连,具有较大的侧向刚度,与传统形式的连梁相比,设计上更加合理,但核心筒处墙体钢筋较密,导致锚杆安装难度大。针对钢连梁安装的施工难点,引入了Tekla三维建模来预测钢连梁锚杆与混凝土墙钢筋的碰撞情况,继而提出处理方案,最终顺利地完成了钢连梁的安装,对类似项目具有指导作用。

The steel coupling beam design has been used for the core-tube from 5th floor to 33rd floor in main building of Kuala Lumpur Landmark Tower in Malaysia. Such steel coupling beam was connected to either side of the wall column by pre-buried boards and bolts, with larger lateral rigidity. Compared with traditional form of coupling beam, this design scheme is more reasonable. However, the arrangement of reinforcing steel bars in the wall is rather dense, and very hard to install bolts. Focusing on this construction difficulty of steel coupling beam installation, Tekla 3D modeling has been introduced to predict whether there are collisions or not between bolts of steel coupling beam and rebars of concrete wall. And then a solution has been put forward and finally the steel coupling beam installation was smoothly completed, which has a guiding role for similar projects in the future.
