Steel plate beam sling bridge
The invention discloses a steel plate beam sling bridge, and relates to the field of bridge engineering. The steel plate beam sling bridge comprises a steel plate beam used as a beam body, an anchoring structure, bridge abutments, pile foundations and handrails, and is characterized in that the steel plate beam is in a sling 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 plate beam body. The overall welding type steel plate beam is adopted to replace a traditional steel cable, an iron chain or a fiber plate to serve as a main stress structure of a beam body, a bearing component of the beam body is combined with a passage slab bridge deck to ensure that the structure of the beam body is stable, and the shape of a sling can reduce the vertical bending moment of the beam body, increase the vertical rigidity of the beam body and reduce vertical deformation; the steel plate beam is formed by welding a top plate serving as a bridge floor, a plurality of transverse inverted-T-shaped longitudinal beams and a plurality of longitudinal diaphragm plates, the transverse rigidity of a beam body can be improved, and the transverse amplitude can be 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板梁悬带桥，涉及桥梁工程领域。本发明的钢板梁悬带桥包括用作梁体的钢板梁、锚固结构、桥台、桩基和栏杆，其特征在于：所述钢板梁呈悬带状，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板梁梁体上。本发明采用整体焊接式钢板梁代替传统的钢索、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，减小竖向变形；钢板梁由作为桥面的顶板、横向多个倒T型纵梁和纵向多个横隔板焊接而成，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。
