摘要
沈阳宝能环球金融中心项目T1塔楼为在建东北第一高楼,其结构形式为巨型外框+伸臂桁架+劲性混凝土核心筒结构,外框巨柱最大截面为5.2m×3.5m,逐渐收缩至1.8m×1.8m。在巨柱安装过程中,其地脚螺栓必须精准定位。本工程为保证地脚螺栓精准定位,在施工过程中提前插入,采用非埋入形式,其柱脚预埋安装采用地脚螺栓进行定位埋设。巨型外框钢柱地脚螺栓埋入筏板基础内,与基础钢筋穿插施工,筏板基础钢柱柱脚通过固定支撑架锚栓定位。
The Tower 1 of Shenyang Baoneng Global Financial Center which is in construction will be the tallest building in the northeast of China, whose structure is composed of mega frame, outrigger and composite steel concrete core. The maximum section dimension of giant column is 5.2m × 3.5m, gradually shrinking to 1.8m × 1.8m. The anchor bolts must be accurately positioned in the installation of giant column. To ensure precise position of anchor bolts and insert them in advance in the construction, the project adopts non-submerged anchor bolts, which are installed by the position of support structure. The giant steel anchor bolts fixed with reinforcing steel bar are embedded in the foundation.
