Ultra-low building height railway bridge simply supported beam structure
The ultra-low building height railway bridge simply supported beam structure comprises a bridge deck slab and two side main beams, the side main beams are arranged at the two ends of the bridge deck slab respectively, the bridge deck slab comprises a shell with an opening in the top and a concrete slab poured in the shell, and the concrete slab is arranged in the shell. A plurality of longitudinal stiffening rib plates and transverse stiffening rib plates are arranged in the shell, a plurality of concrete communicating holes are formed in the longitudinal stiffening rib plates and the transverse stiffening rib plates, a plurality of force transfer welding studs are further fixedly arranged on the inner surface of the shell, and the force transfer welding studs are used for fixedly connecting the concrete slab with the shell. According to the structure, through the combination form of the shell with the open top and the concrete plate, the multiple longitudinal stiffening rib plates and the multiple transverse stiffening rib plates are arranged in the structure, the concrete plate and the steel shell are fixedly connected through the multiple force transmission welding studs, the ultra-low building height is achieved, meanwhile, the bearing capacity and the overall rigidity are greatly improved, and the bending resistance of the structure is remarkably improved.
本发明公开了一种超低建筑高度铁路桥简支梁结构，包括桥面板和两个边主梁，所述边主梁分别设置于所述桥面板的两端，所述桥面板包括顶部敞口的壳体和浇筑于所述壳体内的混凝土板，所述壳体内部设置有多个纵向加劲肋板和横向加劲肋板，所述纵向加劲肋板和所述横向加劲肋板均开设多个混凝土连通孔，所述壳体的内表面还固定设置有多个传力焊钉，所述传力焊钉用于将所述混凝土板与所述壳体固定连接。该结构通过顶部敞口的壳体与混凝土板的组合形式，配以内部多个纵向和横向加劲肋板，采用多个传力焊钉实现混凝土板与钢壳体的固定连接，实现了建筑高度超低化的同时大幅提升了承载能力和整体刚度，显著增强了结构的抗弯性能。
