The invention discloses a quickly-mounted space truss large-span light steel walking bridge and a construction method thereof. The quickly-mounted space truss large-span light steel walking bridge comprises a footpath structure and a handrail structure. The footpath structure comprises a plurality of footpath trusses arranged at intervals. The handrail structure comprises a plurality of handrail trusses, the handrail trusses are arranged on the two sides of every two adjacent footpath trusses, the handrail trusses comprise XZ plane handrail trusses and YZ plane handrail trusses, and the two XZplane handrail trusses are arranged in parallel and are perpendicular to the two YZ plane handrail trusses respectively. By the adoption of a three-dimensional space truss structure, side surface supporting of the handrail trusses is increased, sectional dimensions, perpendicular to a span direction, of the handrail structure and the footpath structure are increased, vertical rigidity and lateralrigidity are improved, and a problem that a pressed surface of the handrail structure is unstable outside is solved. The invention relates to the technical field of bridge construction.
本发明公开了一种快速安装的空间桁架大跨轻钢步行桥及其施工方法，包括步道结构和扶手结构；所述步道结构包括多个间隔设置的步道桁架；所述扶手结构包括多个扶手桁架，扶手桁架设置在相邻两个步道桁架的两侧，所述扶手桁架包括XZ平面扶手桁架和YZ平面扶手桁架，两个XZ平面扶手桁架平行设置，并分别与两个YZ平面扶手桁架垂直。本发明采用三维空间的桁架结构，增加了扶手桁架的侧面支撑，增大了扶手结构和步道结构垂直于跨度方向的截面尺寸，提高了竖向和侧向的刚度，解决了扶手结构受压面外失稳的问题。本发明涉及桥梁建筑技术领域。
