Reticulated shell air precise butt joint positioning method
The invention discloses a reticulated shell aerial precise butt joint positioning method. The method comprises the steps that a reticulated shell construction partition A and a reticulated shell construction partition B are hoisted; carrying out rod piece inlaying installation on support areas in the reticulated shell construction subarea A and the reticulated shell construction subarea B, and measuring to obtain an actual deformation value of a spherical joint at the boundary of the reticulated shell construction subarea A and an actual deformation value of a spherical joint at the boundary of the reticulated shell construction subarea B; a pre-stress tensioning method, a pre-loading method or a supporting method is adopted to adjust the spherical joints of the phase net frame so that the heights of the spherical joints at the boundaries of the construction partitions of the two latticed shells can be consistent, then high-altitude inlaying butt joint of rod pieces at the boundaries between the construction partitions is conducted, and then accurate butt joint positioning of the latticed shells in the air is completed. According to the method, a pre-arching/pre-tensioning/pre-loading/jacking method is provided, high-altitude accurate butt joint positioning of the latticed shell is guaranteed, deformation coordination of the net rack in the self-weight state is controlled, the high-altitude butt joint installation precision of the latticed shell is improved, the construction process is safe and reliable, and the application prospect is good.
本发明公开了一种网壳空中精准对接定位方法，步骤：吊起网壳施工分区A和网壳施工分区B；进行网壳施工分区A和网壳施工分区B内支座区域的杆件嵌补安装，测量得到网壳施工分区A边界处球节点的实际变形值和网壳施工分区B边界处球节点的实际变形值；采用预应力张拉法、预加载法或支顶对相网架球节点进行调整使得两网壳施工分区边界处球节点的高度一致，再进行施工分区之间边界处杆件的高空嵌补对接，即完成了网壳空中精准对接定位。本发明的方法，提供了一套预起拱/预张拉/预加载/支顶的方法保证网壳高空精准对接定位，控制了网架自重状态下的变形协调，提高了网壳高空对接安装精度，施工过程安全可靠，应用前景好。
