Novel steel truss-concrete double-layer combined continuous beam bridge and construction method
The invention relates to a novel steel truss-concrete double-layer combined continuous beam bridge and a construction method. The novel steel truss-concrete double-layer combined continuous beam bridge comprises equal-height section truss piece sets, middle fulcrum bracket truss piece sets, upper-layer steel cross beams, lower-layer steel cross beams, bracket cross beams, cross beam middle web members, cross beam cantilever web members, bracket cantilever web members, shear nail groups, UHPC bridge deck slabs and orthotropic steel combined bridge deck slabs. The equal-height section steel truss girder is a space truss structure system composed of an equal-height section truss piece set, an upper layer steel cross beam, a lower layer steel cross beam, a cross beam middle web member and a cross beam cantilever web member. And the equal-height section steel truss girder is connected with a bracket steel truss girder consisting of a middle fulcrum bracket truss piece group, a bracket cross beam and a bracket cantilever web member through welding. The upper deck of the double-layer combined continuous beam bridge is connected with the UHPC bridge deck and the equal-height section steel truss girder through shear nail groups, and the lower deck of the double-layer combined continuous beam bridge and the equal-height section steel truss girder form a space plate-truss combined system. The structural system is clear in stress, simple in appearance, excellent in anti-seismic performance and high in assembly degree, and has a wide prospect of large-scale application.
本发明涉及一种新型钢桁‑混凝土双层组合连续梁桥及施工方法，包括等高段桁片组、中支点托架桁片组、上层钢横梁、下层钢横梁、托架横梁、横梁中腹杆、横梁悬臂腹杆、托架悬臂腹杆、剪力钉群、UHPC桥面板以及正交异性钢组合桥面板，等高段钢桁梁为等高段桁片组与上层、下层钢横梁及横梁中腹杆和横梁悬臂腹杆组成的空间桁架结构体系。等高段钢桁梁通过焊接与由中支点托架桁片组、托架横梁、托架悬臂腹杆组成托架钢桁梁连接。双层组合连续梁桥上层桥面通过剪力钉群连接UHPC桥面板和等高段钢桁梁，下层桥面与等高段钢桁梁形成空间板桁结合体系。本发明结构体系受力明确，外观简捷，抗震性能优越，装配化程度高，具有规模化应用的广阔前景。
