Segmented construction method for large-span simply-supported string steel truss bridge
The invention relates to the field of steel structure construction, in particular to a large-span simply-supported string steel truss bridge segmented construction method which comprises the steps that bailey trusses are assembled in a segmented mode on the two sides of a river bank at the same time, and the bailey trusses crossing a river channel are erected on temporary buttresses; cranes are arranged on the two sides of the river bank to be matched with stabilizing devices to hoist rod pieces so as to manufacture the middle section of the truss bridge at the same time; the truss bridge middle sections on the two sides of the river bank are simultaneously pushed in place and connected after being manufactured; manufacturing a truss bridge shoreside section on two sides of a river bank by using a crane matched with a stabilizing device; connecting a shoreside section and a middle section of the truss bridge, and arranging an inhaul cable rod on a lower chord of the middle section of the truss bridge; a plurality of steel cables passing through the bottom ends of the inhaul cable rods are arranged on the two shoreside sections of the truss bridge, construction of the whole truss bridge is completed, and the effect that long rod pieces can be stably hoisted is achieved.
本申请涉及钢结构施工的领域，尤其是涉及一种大跨度简支张弦钢桁架桥梁分段施工方法，包括在河岸两边同时进行贝雷架的分段组装，并在临时支墩上进行跨河道的贝雷架的架设；在河岸两边各设置吊车搭配稳固装置进行杆件的起吊以同时进行桁架桥中间段的制造；河岸两边的桁架桥中间段制造完成后同时进行顶推到位并进行连接；使用吊车搭配稳固装置在河岸两边进行桁架桥岸边段的制造；将桁架桥岸边段和中间段进行连接，并在桁架桥种中间段的下弦杆上设置拉索杆；在桁架桥两个岸边段设置数根经过拉索杆底端的钢索，完成整个桁架桥的施工，具备能对较长杆件进行稳定起吊的效果。
