背景技术 Background technique
大跨度钢网架在安装过程中由于网架自重原因，随着网架拼装数量的增加而下挠，为防止网架下挠需要在网架部分下弦球下方支设临时支撑。传统临时支撑采用预先制作的钢管桁架柱或由钢管和扣件搭设的脚手架支撑，支撑架与网架下弦球之间的距离通过放置方木、钢板、砖块等来补足。采用传统临时支撑存在以下两点不足：1. 支撑架与网架下弦球之间的距离通过放置方木、钢板、砖块等来补足，导致支撑不稳定；2. 钢网架就位后需要拆除临时支撑，传统临时支撑拆除时施工难度大，操作方法不当会导致网架局部杆件荷载转换、传递过快从而使网架杆件受力不均，易出现网架局部变形或局部网格变形。 During the installation process, due to the weight of the grid, the large-span steel grid will deflect as the number of grids assembled increases. To prevent the deflection of the grid, it is necessary to set up a temporary support under the lower string ball of the grid. The traditional temporary support is supported by prefabricated steel pipe truss columns or scaffolding erected by steel pipes and fasteners. The distance between the support frame and the lower string ball of the grid frame is made up by placing square wood, steel plates, bricks, etc. The use of traditional temporary supports has the following two disadvantages: 1. The distance between the support frame and the lower string ball of the grid frame is made up by placing square wood, steel plates, bricks, etc., resulting in unstable support; 2. After the steel grid frame is in place, it needs to Remove the temporary support. The construction is difficult when the traditional temporary support is removed. Improper operation methods will lead to the transformation of the load on the local members of the grid, and the transmission will be too fast, which will cause uneven force on the members of the grid, and local deformation or local meshing of the grid will easily occur. out of shape.
