摘要
临沂机场新航站楼结构形式为平面钢管桁架,通过大跨度平面钢管桁架中相贯线切割小、钢管冷弯控制和桁架组拼完成了钢管构件加工。通过方案比选,采用了设置临时支架、起重机换位吊装法,保证了吊装质量及进度。
New terminal building of Linyi Airport adopts plane steel pipe truss structure and the process of steel pipe component is successfully completed through intersecting line cutting in wide-span plane steel pipe truss, cold bending control of steel pipe and truss assembly. After comparison and selection among different schemes, temporary support and crane transposition lifting are adopted to guarantee the lifting quality and construction schedule.
