Prestressed steel-concrete combined box girder suspension splicing construction device
The invention discloses a prestressed steel-concrete combined box girder suspension splicing construction device which comprises a support, the support is provided with a first girder section, a second girder section and a second girder end which are symmetrically hoisted, the second girder end adopts a finish rolling deformed steel bar anchoring device, and two steel boxes are welded and spliced to enable the first girder section and the second girder section to form a cantilever structure. A first connecting hole and a second connecting hole are formed in a finish rolling deformed steel bar. The finish rolling deformed steel bar is used as a prestressed steel bar in the sectional suspended splicing construction stage of the steel box girder. The second girder ends are symmetrically hoisted and accurately positioned. According to the construction method, the finish-rolled deformed steel bars are adopted as prestressing force to conduct cantilever assembly construction on the open steel box girders, and the construction difficulty is small; the cantilever construction without traffic blocking is convenient; and the device has the advantages of saving construction temporary facilities and saving construction cost.
本发明公开了一种预应力钢混组合箱梁悬拼施工装置，包括支座，支座上设置有第一梁段、第二梁段，第二梁端对称吊装而成，第二梁端采用精轧螺纹钢锚固装置，焊接拼装两钢箱使第一梁段与第二梁段形成悬臂结构。精轧螺纹钢上设置有第一连接孔和第二连接孔。精轧螺纹钢作为钢箱梁分段悬拼施工阶段的预应力钢筋。第二梁端对称吊装并精准定位。本发明采用精轧螺纹钢作为预应力先对开口钢箱梁进行悬臂拼装施工装置，具有施工难度小的优点；具有无需阻断交通的悬臂施工便利的优点；具有节省施工临时设施，节约施工成本的优点。
