Arched beam and beam string structure combined large-span beam structure
The invention relates to an arched beam and beam string structure combined large-span beam structure, which adopts an inner-arched outer-chord structural form, and mainly comprises an upper chord rigid member, a flexible inhaul cable, an arch ring, an arch foot connecting piece, a supporting rod, a hinged support, an anti-sliding connecting piece and a locking device. The upper chord rigid component, the flexible inhaul cable and the supporting rod form a conventional beam string structure. The arch rings are arranged between every two adjacent supporting rods and connected with the supporting rods in an assembled mode through the arch foot connecting pieces. The arch ring is additionally arranged in a conventional beam string structure, the arch ring and the upper chord rigid component form a space truss, the rigidity and stability of the beam string structure are enhanced, and the risk of out-of-plane instability is reduced. Meanwhile, the arch structure is adopted inside, so that the internal span of the upper chord rigid component can be increased, the number of the supporting rods is reduced, the length of the supporting rods is reduced, the large-span beam structure has smaller beam height and height-span ratio, and more use space is provided for engineering.
本发明涉及一种拱形梁与张弦梁结合的大跨度梁结构，采用内拱外弦的结构形式，大跨度梁结构主要包括：上弦刚性构件、柔性拉索、拱圈、拱脚连接件、撑杆、铰支座、抗滑连接件、锁紧装置。上弦刚性构件、柔性拉索以及撑杆组成常规的张弦梁。拱圈布置于相邻两撑杆之间，通过拱脚连接件与撑杆进行装配式连接。本发明在常规的张弦梁结构内部增加了拱圈，与上弦刚性构件组成空间桁架，使张弦梁结构的刚度和稳定性得以加强，降低了平面外失稳的风险。同时，内部采用拱结构能够增加上弦刚性构件的内部跨度，减少撑杆的数量，降低撑杆的长度，采用本发明的大跨度梁结构具有更小梁高与高跨比，为工程提供更多的使用空间。
