摘要
H01号厂房网架工程的主厂房平面尺寸216 m,宽144 m,跨度48 m+48 m+48 m。下弦中心标高14 m,正方四角锥网架结构,焊接球下弦周边支撑,采用焊接球节点网架。施工采用现场地面拼装,分块整体吊装,这样可减少高空作业时间,也就减少了高空作业人员的安全隐患,缩短了安装周期。
The main building of H01 plant grid project has a plane size of 216m,a width of 144m and a span of 48m+48m+48m. The lower chord center has an elevation of 14m,a square pyramid structure,and a welded ball under the string support.The welded ball node grid is used.The construction adopts on-site ground assembly and block hoisting,which can reduce the working time of high altitude,which reduces the safety hazard of high-altitude workers and shortens the installation period.
