V-shaped rigid frame single steel box arch rib combination bridge
The invention discloses a V-shaped rigid frame single steel box arch rib combination bridge which comprises a main beam, an upper chord arch, a lower chord arch and diagonal web members are arranged above the main beam, the two ends of the upper chord arch and the lower chord arch and the lower ends of the diagonal web members are all connected with the main beam, two sets of V-shaped inclined legs are fixedly arranged below the main beam, and the V-shaped inclined legs are located below the ends of the upper chord arch and the lower chord arch. Piers are arranged at the bottoms of the V-shaped inclined legs; the arch rib sections of the upper chord arch and the lower chord arch are steel box sections and are different from steel tube concrete arch ribs and reinforced concrete arch ribs; arch ribs of the upper chord arch and the lower chord arch are connected with the main beam through arch foot steel boxes; the lower ends of the diagonal web members are connected with the main beam through finish-rolled deformed steel bars. Compared with the prior art, the method has the advantages that the structure is clear, construction is convenient, structural stress is reasonable, and the design concept is advanced; the design is novel, and the V-shaped structure is large, strong and powerful in rigidity; truss arch ribs are simple, clear, vigorous and modern; a suspender is light, elegant, rigid and soft as a whole, elegant and harmonious, and fully embodies perfect fusion of industry and culture.
本发明公开了一种V形刚构单幅钢箱拱肋组合桥，包括主梁，主梁上方设有上弦拱和下弦拱和斜腹杆，上弦拱与下弦拱两端和斜腹杆下端均与主梁相连接，主梁下方固定设有两组V形斜腿，V形斜腿位于上弦拱、下弦拱的端部下方，V形斜腿底部设有桥墩；上弦拱和下弦拱的拱肋截面为钢箱截面，区别于钢管混凝土拱肋和钢筋混凝土拱肋；上弦拱、下弦拱的拱肋通过拱脚钢箱与主梁连接；斜腹杆下端通过精轧螺纹钢与主梁连接。本发明与现有技术相比的优点在于：结构明确，施工方便，结构受力合理、设计理念先进；造型新颖，V构刚度大遒劲有力；桁架拱肋简洁明快，富于活力及现代感；吊杆轻盈优雅，整体刚柔并济、优雅协调，充分体现工业与文化两者的完美融合。
