Fabricated urban large box chamber steel box girder bridge structure and construction method
The invention relates to a fabricated urban large-box-chamber steel box girder bridge structure which comprises a steel box girder bottom plate, a steel box girder bridge panel, a steel box girder web plate, a steel box girder transverse partition plate and a steel box girder longitudinal partition plate, the steel box girder transverse partition plate and the steel box girder longitudinal partition plate are of a truss structure, and the large-box-chamber steel box girder bridge structure is composed of a plurality of box girder sections in the longitudinal bridge direction. Each box girder section is composed of a steel box girder left section block body, a steel box girder middle section block body and a steel box girder right section block body in the transverse bridge direction, the adjacent section block bodies are connected through ultra-high performance concrete wet joints, and the adjacent box girder sections are connected through ultra-high performance concrete wet joints; the steel box girder middle segment block body comprises a middle block top plate unit and a middle block bottom plate unit which are independent. The problems of welding seam staggering, ultra-wide welding seams and the like encountered by splicing and welding on a construction site after the steel box girders are transported in blocks are solved, the error tolerance rate of on-site splicing after the steel box girders are transported in blocks can be improved, and structural damage caused by welding seam defects of the steel box girders is reduced.
本发明涉及一种装配式城市大箱室钢箱梁桥结构，包括钢箱梁底板、钢箱梁桥面板、钢箱梁腹板、钢箱梁横隔板、钢箱梁纵隔板，所述的钢箱梁横、纵隔板为桁式结构，所述的大箱室钢箱梁桥结构纵桥向由若干箱梁节段组成，所述的箱梁节段横桥向由钢箱梁左节段块体、钢箱梁中节段块体、钢箱梁右节段块体组成，相邻节段块体间和相邻箱梁节段间通过超高性能混凝土湿接缝进行连接；所述钢箱梁中节段块体包括独立的中块顶板单元和中块底板单元。避免了钢箱梁分块运输后在施工现场拼装焊接会遇到的焊缝错台、超宽等问题，有利于提高钢箱梁分块运输后现场拼装的容误差率，减少钢箱梁因为焊缝缺陷所导致的结构损坏。
