Large-span steel tube arch bridge arch rib segmental splicing structure and construction method thereof
The invention belongs to the field of arch bridges, particularly relates to a large-span steel tube arch bridge arch rib segmental splicing structure and a construction method thereof, and provides the following scheme that the large-span steel tube arch bridge arch rib segmental splicing structure comprises a plurality of arch ribs, each arch rib comprises two upper splicing arches and two lower splicing arches, the two upper splicing arches are located above the two lower splicing arches, the two upper splicing arches are arranged in parallel, and the two lower splicing arches are arranged in parallel; a first clamping block enters a second clamping groove, a second clamping block enters a first clamping groove, positioning between a second vertical supporting plate and a first vertical supporting plate is guaranteed, a pushing block is withdrawn, the braking state of an inserting rod is relieved, the inserting rod moves into a second circular groove, and the inserting rod is pushed to move into the second circular groove. And a sliding plate is pushed to move transversely through the two ends of an inserting rod, a second clamping round rod enters two first clamping round grooves, the inserting rod is braked again, the device is prevented from loosening, then pre-fixing can be achieved, the hoisting precision can be improved, and the workload of workers can be reduced.
本发明属于拱桥领域，尤其是一种大跨度钢管拱桥拱肋分节段拼接结构及其施工方法，现提出如下方案，其包括多个拱肋，拱肋包括两个上拼接拱和两个下拼接拱，两个上拼接拱位于两个下拼接拱上方，两个上拼接拱平行设置，两个下拼接拱平行设置，本发明中通过第一卡块进入第二卡槽的内部，第二卡块进入第一卡槽的内部，保证第二竖撑板和第一竖撑板之间的定位，通过推动块收回，解除对插杆的制动状态，插杆移动至第二圆槽的内部，实现矩形板和第一横撑板连接，通过插杆的两端推动滑动板横向移动，第二卡接圆杆进入两个第一卡接圆槽的内部，对插杆进行再次制动，避免装置松动，进而可以实现预固定，并且可以提升吊装精度，降低工人工作量。
