Steel box stacked arch for multi-line operation
The invention discloses a steel box stacked arch for multi-line operation. The steel box stacked arch comprises a straining beam, arch rib structures on the two sides are arranged on the straining beam, and the upper portions of the arch rib structures on the two sides are connected through a transverse support; the straining beam between the arch rib structures provides a driving foundation for an inner driving unit; the straining beam stretches out of the arch rib structures to form a straining beam overhanging part; and the straining beam overhanging part provides a driving foundation for an outer driving unit. And a hanging rod is arranged between a lower arch rib and the straining beam. And an inter-arch connecting rod is arranged between the upper arch rib and the lower arch rib. Thesteel box stacked arch is suitable for operating multiple lines and has the advantages of being good in integrity, high in rigidity, uniform in arch rib stress and the like. By the adoption of rigidsuspenders and the inter-arch connecting rods, the bearing capacity is high and the anti-fatigue performance is good; the axial force and bending moment can be effectively transmitted between arch ribs and between the arch ribs and the straining beam, the straining beam overhanging part can provide a basis for the outer driving unit to travel outside the arch rib structure, and a problem of single-side unbalance loading of the arch rib structure is solved.
本发明公开了一种多条线路运行的钢箱叠拱，包括系梁，所述系梁上设置有两侧的拱肋结构，两侧的拱肋结构上部通过横撑相连，所述拱肋结构之间的系梁为内行驶单元提供行驶基础，所述系梁探出拱肋结构形成系梁悬挑部，所述系梁悬挑部为外行驶单元提供行驶基础。所述下拱肋与系梁之间设置有设置有吊杆。所述上拱肋、下拱肋之间设置有拱间连杆。本发明适用于运行多条线路的钢箱叠拱，具有整体性好，刚度大、拱肋受力均匀等优点。采用刚性吊杆、拱间连杆具有承载能力强、抗疲劳性能好，能有效的在拱肋间及拱肋与系梁间传递轴力和弯矩，系梁悬挑部能够为外行驶单元在拱肋结构外行驶提供基础，解决了拱肋结构单侧偏载的问题。
