Combined box girder structure and construction method thereof
The invention discloses a combined box girder structure and a construction method thereof, the combined box girder structure comprises a box-shaped shell and an inner core, the inner core comprises a thin-wall steel shell, a shearing force connecting piece and a transverse partition plate, and the thin-wall steel shell is fixedly attached to the interior of the box-shaped shell through the shearing force connecting piece. The inner core and the box-shaped shell of the combined box girder structure are jointly stressed, the thickness of a plate can be further reduced, the self weight of the structure is reduced, the effectiveness of the structure for resisting use loads is improved, the spanning capacity of a box girder bridge is improved, the inner core is directly used as an internal formwork of the box-shaped shell, rapid construction of bridge construction is achieved, and the construction cost is reduced. The defects of conventional pouring are avoided, the problems of overlarge transverse local stress, overall stability, section distortion, web shear bearing capacity and the like can be solved, and good durability and wide application prospects are achieved.
本发明公开了一种组合箱梁结构及其施工方法，组合箱梁结构包括箱型外壳和内芯，内芯包括薄壁钢壳、剪力连接件和横隔板，薄壁钢壳通过剪力连接件贴合固定在箱型外壳的内部。本发明中组合箱梁结构的内芯与箱型外壳共同受力，可进一步降低板件厚度，减轻结构自重，提高结构抵抗使用荷载的有效性，增大箱梁桥的跨越能力，且内芯直接作为箱形外壳的内部模板，实现桥梁建设的快速化施工，既避免了常规浇筑缺陷，又可解决横向局部应力过大、整体稳定性、截面畸变和腹板抗剪承载力等问题，具有良好的耐久性和广阔的应用前景。
