Large-span steel grid structure and construction technology thereof
The large-span steel grid structure comprises a grid frame and supporting columns, the supporting columns are located on the two sides of the bottom of the grid frame correspondingly, supporting mechanisms are arranged on the inner sides of the supporting columns, and each supporting mechanism comprises a sliding column, a sliding block, a buffer spring, a movable rod, a movable plate, a supporting plate, a limiting block, a limiting groove, a hanging column, a transverse rod and an inhaul cable. Sliding columns are fixedly connected to the lower half portions of the inner sides of the supporting columns through bolts, sliding blocks are slidably connected to the two sides of the surfaces of the sliding columns, integrally-formed fixing bases are arranged on the tops of the supporting columns, and the fixing bases are attached to the bottom of the net rack frame. The net rack frame is supported through the supporting plates, so that the stability of the net rack frame is improved, and the problem that a large-span steel net rack structure is large in space structure span, consequently, the self weight of the structure is too large, and consequently the stability is poor is solved; and meanwhile, stress of the transverse rod and the hanging columns can be dispersed through the inhaul cables, and the overall stability can be further enhanced.
本发明公开了一种大跨度钢网架结构及其施工工艺，包括网架框和支柱，所述支柱分别位于网架框底部的两侧，所述支柱的内侧设置有支撑机构，所述支撑机构包括滑柱、滑块、缓冲弹簧、活动杆、活动板、支撑板、限位块、限位槽、吊柱、横杆和拉索，所述支柱内侧的下半部均通过螺栓固定连接有滑柱，所述滑柱表面的两侧均滑动连接有滑块，所述支柱的顶部均设置有一体成型的固定座，所述固定座贴合于网架框的底部。通过支撑板对网架框进行支撑，从而提高了网架框的稳定性，克服了大跨度钢网架结构存在空间结构跨度大，导致其结构本身自重过大，从而导致稳定性欠佳的问题发生；同时利用拉索使横杆和吊柱能够分散受力，有助于进一步增强整体稳定性。
