Steel-concrete composite beam structure formed by connecting steel pipe longitudinal beam and concrete bridge deck slab
The invention provides a steel-concrete composite beam structure formed by connecting steel pipe longitudinal beams and a concrete bridge deck slab, and relates to the field of bridge superstructures, each steel pipe longitudinal beam is composed of a complete hollow circular steel pipe, the number of the steel pipe longitudinal beams is two, and a plurality of cross beams are arranged between the two steel pipe longitudinal beams and are arranged at equal intervals in the length direction of the steel pipe longitudinal beams; the concrete bridge deck internally provided with a steel reinforcement framework is formed by pouring concrete and is connected with the two steel pipe longitudinal beams through the shear nails to form a combined beam structure. The shear nails are evenly welded to the surface, making contact with the concrete bridge deck slab, of the upper semicircle of the steel pipe longitudinal beam. And the fulcrum core filling concrete is a concrete solid section poured in an internal empty bin at the end fulcrum and the middle fulcrum of the steel pipe composite beam. The compressive property of the concrete and the tensile property of the steel structure are perfectly utilized, the steel pipe is filled with the concrete in the hogging moment area to form a double-combination effect, and the stress performance of a traditional steel plate combination structure is improved.
本发明提出了一种钢管纵梁与混凝土桥面板连接形成钢混组合梁结构，涉及桥梁上部结构领域，钢管纵梁由一根完整的空心圆钢管构成，设置有两个，两个所述钢管纵梁之间设有若干个横梁，并沿着所述钢管纵梁长度方向等间距布置；混凝土桥面板内含钢筋骨架由混凝土浇筑而成，通过所述剪力钉与两个所述钢管纵梁连接成组合梁结构；所述剪力钉均匀焊接在所述钢管纵梁的上半圆与所述混凝土桥面板接触的表面；支点填芯混凝土为钢管组合梁的端支点和中支点处内部空仓内浇筑的混凝土实心段。本发明完美的利用了混凝土的抗压性能和钢结构的抗拉性能，在负弯矩区域，钢管内填充混凝土形成双组合作用，改善传统钢板组合结构的受力性能。
