Steel box girder sling bridge
The invention discloses a steel box girder sling bridge, and relates to the field of bridge engineering. The steel box girder suspension belt bridge comprises a steel box girder used as a girder body, an anchoring structure, bridge abutments, pile foundations and handrails, and is characterized in that the steel box girder is in a suspension belt shape and is fixed between the bridge abutments at the two ends through the anchoring structure, the bridge abutments are fixed on the pile foundations, and the handrails are fixedly installed on the steel box girder body. The overall welding type steel box girder is adopted to replace a traditional steel cable, an iron chain or a fiber board to serve as a main stress structure of a girder body, a bearing component of the girder body is combined with a passage slab bridge deck to ensure that the structure of the girder body is stable, the shape of a sling can reduce the vertical bending moment of the girder body and increase the vertical rigidity of the girder body, and therefore vertical deformation is reduced; the steel box girder is formed by welding a plurality of box chambers in the transverse direction, the transverse rigidity of a girder body can be improved, and the transverse amplitude is reduced; the use comfort is good, the processing and the installation are easy, and the cost is relatively low.
本发明公开了一种钢箱梁悬带桥，涉及桥梁工程领域。本发明的钢箱梁悬带桥包括用作梁体的钢箱梁、锚固结构、桥台、桩基和栏杆，其特征在于：所述钢箱梁呈悬带状，并通过锚固结构固定在两端的桥台之间，所述桥台固定在桩基之上，所述栏杆固定安装在钢箱梁梁体上。本发明采用整体焊接式钢箱梁代替传统的钢索、铁链或纤维板作为梁体主要受力结构，把梁体的承重构件与通行道板桥面结合在一起，以保证梁体结构稳定，悬带形状可减小梁体竖向弯矩，增加梁体竖向刚度，从而减小竖向变形；钢箱梁横向由多个箱室焊接而成，可增加梁体的横向刚度，降低横向振幅；使用舒适性好，加工安装容易，成本相对较低。
