河南省体委田径训练馆网架工程复盖面积为4057m~2,于1985年6月25日至7月3日采用双柱升板机整体提升网架成功,节省了施工用钢量,简化了网架提升工艺。经一年多观察证明工程质量优良。此大面积网架用升板机提升及当纵横之比为2.3∶1情况下,采用中部双层网架,解决了挠度问题,在国内尚属不多。 Henan Province Sports Commission Athletics Training Center grid structure covered an area of ​​4057m~2. From June 25 to July 3, 1985, the double-pillar lifting machine was used to lift the grid as a whole, saving the amount of steel used for construction and simplifying Grid lift technology. After more than one year of observation, the quality of the project was excellent. This large-area grid was lifted by a riser and when the aspect ratio was 2.3:1, the central double-layer grid was used to solve the problem of deflection, which was not much in China.
