Continuous steel box girder structure suitable for bridge widening section and construction method of continuous steel box girder structure
The invention discloses a continuous steel box girder structure suitable for a bridge widening section and a construction method of the continuous steel box girder structure. The construction method comprises the steps that a multi-box single-chamber structure is adopted, the width of a single box chamber is controlled to be kept unchanged, a plurality of equal-width box chambers are prefabricated in a factory respectively, longitudinal segmental automobile hoisting is adopted on site, or the continuous steel box girder structure is gradually pushed forwards in the longitudinal direction for construction; longitudinal connection construction of a plurality of box chambers is achieved; middle widening top plate connecting sections are connected among the plurality of equal-width box chambers, and the middle widening top plate connecting sections among the box chambers are adjusted to adapt to the width change of the bridge floor; solid-web type transverse partition plates between the box chambers are installed at equal intervals in the longitudinal direction of the bridge, and a frame type transverse partition plate is densely arranged in the middle of the solid-web type transverse partition plates so as to achieve connection between the multiple box chambers in the transverse direction. By the adoption of the multi-box single-chamber variable-width steel box girder scheme, the construction and installation difficulty of the whole steel box girder is small, stress is clear and definite, and the construction quality can also be guaranteed.
本发明公开了一种适用于桥梁变宽段的连续钢箱梁结构及其施工方法，所述方法包括：采用多箱单室结构，控制单个箱室宽度保持不变，多个等宽箱室分别采用工厂预制，现场采用纵向分节段汽车吊装，或采用沿纵向逐步顶推前进施工，实现多个箱室纵向连接施工；多个等宽箱室之间连接中部变宽顶板连接段，通过调整箱室之间的中部变宽顶板连接段来适应桥面宽度变化；沿桥梁纵向等间隔再安装箱室之间的实腹式横隔板，在实腹式横隔板中间加密布置一道框架式横隔板，以实现横向多个箱室之间的连接。采用本发明多箱单室的变宽钢箱梁方案，整联钢箱梁施工安装难度较小，受力较为清晰明确，施工质量也能得到保证。
