论文摘要
[摘要]广州新电视塔钢结构外筒由钢管混凝土立柱、钢管环梁和钢管斜撑组成。其外框筒大型倾斜脚是钢结构外框筒定位和安装的基础,由于柱脚安装与混凝土施工穿插进行,需消除混凝土施工造成的安装偏差;倾斜柱脚采用锚栓群固定连接,定位困难且要求高。柱脚预埋锚栓均采用定位支架、定位环板控制其安装精度。通过采取标高调整,二次埋设等技术措施,消除了混凝土施工造成的安装偏差,达到了锚栓孔无一扩孔,一次安装到位的要求。

Construction Technology of Large Inclined Column Bases
in Guangzhou New TV Tower

Abstract:External steel tube of  Guangzhou New TV Tower is composed of concrete filled steel tube columns, steel tube circle beams and steel tube inclined bracings. As the foundation of external steel frame tube location and installation, the  construction of large inclined column bases is inserted with concrete construction, so installation deviation caused by concrete construction should be eliminated. Furthermore, the inclined column bases are fixed by anchor bolts group with high requirements, so it is difficult to locate them. Location bracings and annular plates are adopted for embedded anchor bolts to control installation precision. Through elevation adjustment and the second embedding,  installation deviations induced by concrete construction are eliminated, and the requirement that all anchor bolts are installed for one time without expanded hole is satisfied.
