Construction method of ground jacking assembly space curved surface grid structure
The invention provides a construction method for assembling a spatial curved surface grid structure through ground jacking. The construction method comprises the following steps: firstly, arranging a circular tube support at a lower chord ball position of a starting unit module, and selecting a midspan sequence of grids to assemble the starting unit module; then, jacking devices are symmetrically and sequentially installed at the jacking point positions selected through calculation and analysis of the starting unit module; then the starting unit modules are synchronously jacked to a proper height at which an operator can conveniently assemble the starting unit modules, and the starting unit modules continue to be assembled towards the two sides in sequence; and when the net distance between the lowest point of the assembled grid and the ground is not enough to continue to assemble the grid, the steps are repeated, the assembled grid units continue to be jacked upwards, and the assembled units are expanded on the two sides at the same time till the whole grid is assembled. The splicing height of the net rack on the ground can be reduced, the construction difficulty is reduced, the construction efficiency is improved, and meanwhile a large number of measure materials are saved.
本申请提供了一种地面顶升拼装空间曲面网架结构的施工方法。所述施工方法首先在起步单元模块下弦球位置设置圆管支撑，选择跨中数列网格拼装成起步单元模块；然后，在起步单元模块计算分析选定的顶升点位置对称依次安装顶升设备；再将起步单元模块同步顶升到方便作业人员拼装的合适高度，依次向两侧继续拼装起步单元模块；当拼装好的网格最低点和地面的净距离不足以继续拼装网格时，重复上述步骤，将拼装完成的网架单元继续向上顶升，两侧同时进行扩大拼装单元，直到网架整体拼装完成。本发明能够降低网架在地面拼装高度，减小施工难度，提高施工效率，同时节约了大量措施材料。
