天津滨海国际机场T2航站楼主楼屋盖钢网架施工分析

摘要
天津滨海国际机场T2航站楼主楼屋盖工程结构复杂,跨度大,钢构件种类及数量多。采用了提升和吊装联合施工方法,其中吊装区布置在建筑物外侧,分为吊装1区、2区和悬挑区3部分,采用地面拼装,设置临时支撑和分块吊装等施工步骤。为有效地控制网架变形,提高安装精度,施工前对分块吊装和支撑卸载过程进行了仿真分析,结果表明:该网架结构在施工各阶段,内力和变形值均在合理范围内。
The main building roof has complex structure and large span and kinds of steel members in Tianjin Binhai International Airport Terminal 2. The roof truss is constructed by lifting and hoisting. The hoisting area is around the building and is divided into section 1,section 2 and cantilever section. The roof truss is installed on ground and set temporary supports and partition hoisted. In order to control the deformation of truss and improve precision,the course of hoisting and unloading is simulated,the results show that the internal force and deformation are within reasonable bounds.
