Steel-concrete plate truss combined bridge deck structure
The invention belongs to the technical field of steel truss girders, and particularly relates to a steel-concrete plate truss combined bridge deck structure. Comprising a main truss lower chord and a steel-concrete combined bridge deck structure, wherein the main truss lower chord comprises a side truss lower chord and a middle truss lower chord; the steel-concrete combined bridge deck structure comprises an integral steel plate, PBL shear keys, longitudinal perforated steel bars, common longitudinal steel bars, common transverse steel bars and cast-in-place concrete. The integral steel plates are lapped between every two middle girder lower chords or between the middle girder lower chords and the side girder lower chords; the PBL shear keys are welded on the top surface of the integral steel plate; the longitudinal perforated steel bars penetrate through the circular holes of the PBL shear keys to be overlapped on the PBL shear keys; the common longitudinal steel bars are lapped on the top surfaces of the PBL shear keys; the common transverse steel bars are lapped on the common longitudinal steel bars; cast-in-place concrete is poured on the top surface of the integral steel plate; the steel truss girder bridge is simple in structure, reasonable in design, convenient to construct, excellent in mechanical property, good in using effect and capable of being applied to a through type steel truss girder bridge and a semi-penetrating type steel truss girder bridge.
本发明属于钢桁梁桥技术领域，具体涉及一种钢混板桁组合桥面结构；包括主桁下弦杆和钢混组合桥面结构，主桁下弦杆包括边桁下弦杆和中桁下弦杆；钢混组合桥面结构包括整体钢板、PBL剪力键、纵向穿孔钢筋、普通纵向钢筋、普通横向钢筋以及现浇混凝土；整体钢板搭接于中桁下弦杆两两之间或中桁下弦杆与边桁下弦杆之间；PBL剪力键焊接于整体钢板顶面；纵向穿孔钢筋穿过PBL剪力键的圆形开孔搭置在PBL剪力键上；普通纵向钢筋搭置在PBL剪力键顶面；普通横向钢筋搭置在普通纵向钢筋上；现浇混凝土浇筑在整体钢板顶面；其结构简单、设计合理、施工方便且力学性能优良、使用效果好，能应用于下承式钢桁梁桥以及半穿式钢桁梁桥。
