Large-span overweight special-shaped arch truss steel body structure
The invention discloses a large-span overweight special-shaped arch truss steel body structure which comprises a trapezoid arch steel body, the trapezoid arch steel body is connected with a curve-shaped arch truss through a catenary linear arch connecting piece, a space grid net is arranged on a cable-stayed arch steel body, structural stress is optimized by adopting the space grid net, the material consumption is reduced, and the construction cost is reduced. And by arranging the detachable arch truss, the structure is convenient to detach, and the installation difficulty and cost are reduced. The prestressed arch-shaped connecting frame and the reinforcing ribs of the arch-shaped structure are arranged at the splicing welding plates, so that the structural strength is enhanced. Reinforcing steel plates are welded and connected to the hoisting joints, hoisting safety is improved, prestress is applied to the arch structure by arranging the cable-stayed arch steel bodies and the prestress arch connecting frames, the rigidity and stability of the structure are enhanced, and the bearing capacity of the structure is improved. By connecting the trapezoidal arched steel body and the curved arch truss with the catenary linear arched connecting piece, the flexible connection of the special-shaped arch truss steel body is realized, and the construction requirements under complex terrains are met.
本发明公开了一种大跨超重异形拱桁架钢体结构，包括梯形拱形钢体，梯形拱形钢体通过悬链线形拱形连接件与曲线形拱桁架相连接，斜拉式拱形钢体上设置有空间网格网，通过采用空间网格网优化结构受力，减少材料用量，通过设置拆卸式拱桁架，方便进行结构拆卸，降低安装难度和成本。通过在拼接焊板处设置预应力拱形衔架与拱形结构的加强肋，增强结构强度。在吊装节点处焊接连接加固钢板，提高吊装安全性通过设置斜拉式拱形钢体和预应力拱形衔架，对拱形结构施加预应力，增强结构的刚性和稳定性，提高结构承载能力。通过将梯形拱形钢体和曲线形拱桁架与悬链线形拱形连接件相连接，实现异形拱桁架钢体的灵活连接，满足复杂地形下的施工需求。
