Large-span concrete-filled steel tube arch bridge supporting structure
The invention relates to the technical field of large-span arch bridge structures, solves the problem that in the prior art, the structure is unstable in the long-term using process, and discloses a large-span concrete-filled steel tube arch bridge supporting structure which comprises an arch rib, base bodies and a plurality of suspenders. The suspenders are arranged on the arch rib at intervals, extend downwards and are connected with the bridge deck slab, the arch rib and the suspenders are of hollow structures and are used for pouring concrete, the arch rib and the suspenders are communicated with each other, the arch rib comprises a plurality of subsection bodies, the suspenders are connected to the joints of the subsection bodies, and the subsection bodies abut against each other. The segmented bodies are connected through first connecting pieces and the suspenders, and every two adjacent segmented bodies are connected through a second connecting piece. The concrete can be poured into the steel structure, so that the stress strength of the supporting structure is improved, and the stability of the supporting structure is enhanced.
本申请涉及大跨径拱桥结构的技术领域，改善了现有技术在长期使用过程中会存在结构不稳定的问题，公开了一种大跨径钢管混凝土拱桥支撑结构，其包括拱肋、座体和若干吊杆，座体设置于土体中，座体设置于拱肋两个端，若干吊杆间隔设置于拱肋上，吊杆向下延伸并连接桥面板，拱肋和吊杆均为中空结构用于浇筑混凝土，拱肋和若干吊杆均相互连通，拱肋包括若干分段体，吊杆连接于若干分段体的连接处，分段体之间相互抵接，且分段体之间通过第一连接件与吊杆连接，相邻两个分段体之间通过第二连接件连接。本申请能够通过向钢结构内灌注混凝土，增加支撑结构的受力强度，增强支撑结构的稳定性。
