Steel-concrete composite structure bridge and construction method
The invention discloses a steel-concrete composite structure bridge and a construction method, the steel-concrete composite structure bridge comprises an upright composite beam section and a cantilever type inverted composite beam section, and the cantilever type inverted composite beam section is connected with the upright composite beam section through an upright and inverted beam joint connecting section; the cantilever type inverted combination beam section is arranged to be of an upper steel box beam structure and a lower concrete layer structure. The upper layer structure of the upright composite beam is arranged to be an upper concrete layer structure and a lower steel box beam structure, or the upright composite beam is of an all-steel box beam structure. According to the steel-concrete composite structure bridge and the construction method, the upright composite beam sections are used for bearing sagging moment, the inverted composite beams are used for bearing hogging moment, different structures are adopted for specific stress areas of the bridge to bear external force, the deformation resistance of the composite beams is improved, and the service life of the composite beams is prolonged. The problem that a traditional steel-concrete composite beam is limited by cracking of a bridge deck slab in a hogging moment area is solved, prestress does not need to be tensioned in the cantilever type inverted composite beam section suspension splicing process, temporary piers do not need to be erected during construction, and construction is convenient.
本发明公开了一种钢混组合结构桥梁及施工方法，该钢混组合结构桥梁包括正置组合梁段和悬臂式倒置组合梁段，悬臂式倒置组合梁段与正置组合梁段通过正倒梁接缝连接段连接，悬臂式倒置组合梁段设置为上钢箱梁结构和下混凝土层结构；正置组合梁的上层结构设置为上混凝土层结构和下钢箱梁结构，或者，正置组合梁为全钢箱梁结构。本发明公开的钢混组合结构桥梁及施工方法，正置组合梁段用于承受正弯矩，倒置组合梁用于承受负弯矩，针对桥梁的特定受力区域采用不同的结构来承受外力，增加了组合梁的抗变形能力，解决了传统的钢混组合梁受限于负弯矩区桥面板开裂的问题，悬臂式倒置组合梁段悬拼过程无需张拉预应力，施工不需要搭设临时墩，施工方便。
