Longitudinal stiffening rib connecting structure of closed steel box composite beam bridge
The invention relates to a longitudinal stiffening rib connecting structure of a closed steel box composite beam bridge, which comprises a composite beam, a stiffening rib, a concrete bridge deck and bottom plate concrete, the closed steel box girder is composed of a top plate, a web, a bottom plate, web longitudinal stiffening ribs, top plate longitudinal stiffening ribs, bottom plate longitudinal stiffening ribs and a truss type diaphragm system, and the longitudinal stiffening ribs are arranged on the upper surface of the top plate of the closed steel box girder and serve as shear connectors of the steel girder and the concrete bridge deck; longitudinal stiffening ribs with high rigidity and small sectional area are arranged on the lower surfaces of the top and bottom plates of the steel box girder in the sagging moment area; longitudinal stiffening ribs with large sections are arranged on the lower surface of the steel box girder top plate in the hogging moment area; a hogging moment area steel box beam bottom plate adopts longitudinal stiffening ribs penetrating through reinforcing steel bars and cast-in-place concrete, and is also used as a steel beam and bottom plate concrete shearing force connecting piece; the transverse partition system is in a truss type and is longitudinally arranged at equal intervals.
本发明涉及一种闭口钢箱组合梁桥纵向加劲肋连接构造，包括：组合梁、加劲肋、混凝土桥面板和底板混凝土，其中：组合梁的钢梁采用闭口钢箱梁，闭口钢箱梁由顶板、腹板、底板、腹板纵向加劲肋、顶板纵向加劲肋、底板纵向加劲肋和桁架式横隔系组成，闭口钢箱梁的顶板上表面布置纵向加劲肋，兼作钢梁与混凝土桥面板剪力连接件；正弯矩区钢箱梁顶底板下表面采用刚度大、截面积小的纵向加劲肋；负弯矩区钢箱梁顶板下表面采用截面大的纵向加劲肋；负弯矩区钢箱梁底板采用贯穿钢筋和现浇混凝土的纵向加劲肋，兼作钢梁与底板混凝土剪力连接件；横隔系采用桁架式，纵向等间距布置。
