Temporary connecting structure for steel pipe arch ring sections
The invention discloses a temporary connecting structure for steel pipe arch ring sections. The temporary connecting structure comprises a plurality of lug plates located outside the arch ring sections, all the lug plates are arranged at intervals in the circumferential direction of the arch ring sections, the lug plates are fixedly connected with the outer walls of the steel pipes of the arch ring sections, a plurality of brackets are further connected between the lug plates and the outer walls of the steel pipes, and the lug plates of every two adjacent arch ring sections are connected through bolts. The lug plates and the brackets are arranged on the outer walls of the steel pipes of the arch ring sections, so the internal structures of the steel pipes are not affected, flowing of concrete is not affected at all when the concrete in the pipes is pressed and injected, and the compactness of the concrete in the pipes is guaranteed; all the lug plates are arranged at intervals in the circumferential direction of the arch ring sections, the installation workload of connecting bolts is reduced, and the lug plates are arranged outside the steel pipe, so alignment installation operation is more convenient, the aerial work time is shortened, and the construction risk is reduced; and after permanent weld joint welding of the arch ring sections is completed, the temporary connecting structure can be directly cut off, steel can be recycled, and energy conservation and environmental protection are better facilitated.
本发明公开了一种钢管拱圈节段临时连接构造，包括多个位于拱圈节段外部的耳板，所有耳板沿着拱圈节段的周向间隔设置，且耳板和拱圈节段的钢管外壁固定连接，在耳板和钢管外壁之间还连接有多个牛腿，相邻两个拱圈节段的耳板之间通过螺栓相连接。本发明将耳板和牛腿均设置在拱圈节段的钢管外壁，不影响钢管内部结构，管内混凝土压注时对混凝土的流动无任何影响，保证了管内混凝土的密实性；所有耳板沿着拱圈节段的周向间隔设置，减少了连接螺栓的安装工作量，耳板布置在钢管的外部，更加便于对位安装操作，缩短了高空作业时间，降低了施工风险；完成拱圈节段的永久焊缝焊接后，临时连接构造可直接切除，钢材可再回收利用，更利于节能环保。
