Foot bridge structure
The invention relates to a foot bridge structure, and belongs to the technical field of simple suspension bridges in bridge engineering. The Bailey pieces universal in the industry are adopted as the stiffening beams and the handrails, the rigidity of the foot bridge can be improved, and meanwhile the problems that a steel truss is large in machining difficulty and high in cost are solved. The deformation control measure is adopted, the vertical rigidity of the bailey piece stiffening beam can be guaranteed, the pre-camber problem is solved, meanwhile, the nonlinear deformation influence generated by bailey piece pin joint is eliminated, and the calculation workload of the suspension bridge is reduced. The first steel wire rope is adopted as the suspender and connected with the main cable through the steel wire rope inserting and weaving technology, connecting pieces are reduced, and the cost and the construction period are saved. The multiple second steel wire ropes are adopted as the main cable, the steel wire ropes are universal products in the industry, spot goods exist in the market, and ordering and machining are not needed. The cable saddle and the cable clamp assembly are both standard components and can adapt to main cables of different specifications, and the condition of universal products is met.
本发明涉及一种人行桥结构，属于桥梁工程中的简易吊桥技术领域。本发明采用行业通用的贝雷片作为加劲梁同时兼顾栏杆，可以实现提高人行桥刚度，同时避免钢桁架加工难度大及费用高的问题。本发明采用变形控制措施，可以保证贝雷片加劲梁的竖向刚度，解决预拱度问题，同时消除贝雷片销接产生的非线性变形影响，减少了吊桥的计算工作量。本发明采用第一钢丝绳作为吊杆，利用钢丝绳插编技术与主缆连接，减少了连接件，节约了成本和工期。本发明采用的是多根第二钢丝绳作为主缆，钢丝绳为行业通用产品，市场上存在现货，不需要订购加工。本发明中的索鞍和索夹组件均采用标准构件，可以适应不同规格的主缆，达到通用产品的条件。
