摘要
河南省体育场网架跨度273m,总高度为51 5m。施工中采用网架从跨中开始安装保证网架支座的准确定位,利用网架外环局部支承在看台外圈钢筋混凝土环梁上的有利条件平衡水平推力的影响,网架节点采用全站仪确定安装位置,脚手架均匀卸除网架荷载等措施,圆满完成施工任务。
The grid frame of He'nan Stadium is 273 meters wide and 51.5 meters high.In construction,engineers adopted many measures to complete construction successfully,including installing this grid frame from mid-span to ensure precise location of supports of the grid frame,utilizing the advantage of some parts of the external ring of the grid frame supported by the external reinforcement concrete ring beam of stadium stands to balance the influence of horizontal pushing forces,using total stations to determine correct installation positions of nodes of the grid frame,and removing evenly scaffolding to unload loading of the grid frame and so forth.
