摘　　要：国家会展中心(天津)一期工程中央大厅复杂树形分杈钢结构的安装施工多为高空作业,且倾斜构件不易设置防护措施。针对十字箱形柱、树形分杈结构、顶部圈梁施工,设计专用的操作平台,并确定安装方法,有效解决树形结构的安全防护问题,为作业人员提供良好的作业平台及安全保障,保证顺利施工的同时能及时周转利用材料,节约成本。In the installation and construction of the phase I of the National Convention and Exhibition Center(Tianjin) project,the complex tree-shaped steel structures in the central hall are mostly carried out at height,and the inclined members are not easily set up for protective measures.The special operation platform is designed for the construction of cross box columns,tree-shaped branch structures and top ring beams.The method of installation is also determined to effectively solve the problem of safe protection concerning tree-shaped structures,to offer operators a good working platform and the measures for their safety,ensure a successful construction,a timely utilization in circulation of materials,and save the cost.
