摘　　要：针对大跨度钢-混组合梁桥面板及翼缘板为现浇结构的组合梁桥,存在浇筑支架搭拆复杂且难度大的施工问题。论文提出了一种预应力钢-混组合箱梁悬拼施工装置,采用精轧螺纹钢锚固装置作为锚固措施,对开口钢箱梁进行悬臂拼装施工,给出了无支架施工技术方案与施工步骤。For the composite beam bridge with large span steel reinforce concrete composite beam bridge whose panel and flange plate are cast-in-place structure,there is a complicated and difficult construction problem.In this paper,a suspension construction device of prestressed steel-concrete composite box girder is proposed.The cantilever construction of open steel box girder is carried out by adopting fine rolled rebar anchoring device as anchoring measure.The technical scheme and procedure of construction without support are given.
