Triangular assembly type highway steel bridge
The invention discloses a triangular assembly type highway steel bridge which is formed by assembling trusses, a bridge deck system and flat longitudinal joints. Each basic truss piece is formed by connecting a single standard truss piece or two standard truss pieces through bolts, each standard truss piece is a basic unit composed of chord members, vertical web members and diagonal web members, the chord members are made of double-channel steel, and the vertical web members and the diagonal web members are made of rectangular steel pipes or I-shaped steel. The basic truss pieces are connected through bolts to form the truss. The horizontal supports are connected with the chord member gusset plates through bolts, the vertical supports are fixed on the vertical web members through bolts to form a stable whole, and the horizontal supports and the vertical supports are made of channel steel. The cross beams are transversely located on cross beam base plates at the tops of chord members, the cross beams are longitudinally fixed to vertical web members through bolts, wind-resistant pull rods are connected with the ends of the cross beams through bolts, a plurality of bridge deck slabs are flatly laid at the tops of the cross beams and fixed to the cross beams through bolts, and finally the trusses, the bridge deck system and the longitudinal beams form a whole and are jointly stressed. The standard truss piece is light in weight and fast in assembly and combination, and can effectively solve the problem of emergency traffic protection of highway bridges with different spans.
本发明公开了一种三角形装配式公路钢桥，由桁架、桥面系和平纵联组装。基本桁架片由单片或者两片标准桁架片通过插销连接而成，标准桁架片由弦杆、竖腹杆、斜腹杆组成的基本单元，弦杆采用双槽钢，竖腹杆和斜腹杆采用矩形钢管或工字钢。基本桁架片之间通过插销连接构成桁架。水平支撑与弦杆节点板通过螺栓连接，竖向支撑通过螺栓固定于竖腹杆上，组成稳定整体，水平支撑和竖向支撑均采用槽钢。横梁横向座于弦杆顶部的横梁垫板，纵向通过螺栓将固定于竖腹杆，抗风拉杆与横梁端部通过螺栓连接，多片桥面板平铺于横梁顶部，通过螺栓固定于横梁，最终桁架、桥面系和平纵联形成整体并共同受力。该标准桁架片重量轻，拼装组合快，能有效解决不同跨径公路桥梁的应急保通问题。
