Large cantilever steel box girder
The invention discloses a large cantilever steel box girder, which comprises a top plate, a bottom plate, an inner side web plate, an outer side web plate, a main box chamber diaphragm plate, an inclined bottom plate, a cantilever web plate, a cantilever box chamber diaphragm plate, a top plate longitudinal stiffening rib, a bottom plate longitudinal stiffening rib, an inner side web plate longitudinal stiffening rib, an outer side web plate first longitudinal stiffening rib and an outer side web plate second longitudinal stiffening rib, wherein one outer side web plate second longitudinal stiffening rib is arranged on the inner side surface of the outer side web plate, and is arranged corresponding to the inner side edge of the inclined bottom plate; the cantilever box chamber diaphragm plate comprises a diaphragm plate web, a diaphragm plate flange plate, an inclined strut and a gusset plate. The main box chamber is a main longitudinal stress component, the diaphragm plate of the cantilever box chamber adopts a structure combining a solid-web diaphragm plate and an open-web truss, and the requirements for beam width and transverse stress are met. The structure is clear in stressform, enough transverse rigidity is provided, the structure is light, cantilevers of the whole bridge are unified, factory construction is facilitated, and the structure is suitable for equal-height steel box girder bridges and variable-height and variable-width steel box girder bridges.
一种大挑臂钢箱梁，包括顶板、底板、内侧腹板、外侧腹板、主箱室横隔板、斜底板、挑臂腹板、挑臂箱室横隔板、顶板纵向加劲肋、底板纵向加劲肋、内侧腹板纵向加劲肋、外侧腹板第一纵向加劲肋、外侧腹板第二纵向加劲肋；外侧腹板的内侧面上设有一根外侧腹板第二纵向加劲肋，外侧腹板第二纵向加劲肋对应斜底板的内侧边设置；挑臂箱室横隔板包括横隔板腹板、横隔板翼缘板、斜撑、节点板。主箱室为主要纵向受力构件，挑臂箱室的横隔板采用实腹式横隔板和空腹式桁架相结合的结构，满足了梁宽和横向受力要求，该构造受力形式明确，提供足够的横向刚度且结构轻盈，全桥挑臂统一，便于工厂化施工，既适用于等高钢箱梁桥，又适用于变高变宽钢箱梁桥。
