The invention discloses a space truss light steel walking bridge connected through disc nodes and a construction method thereof. The space truss light steel walking bridge comprises a footpath structure and handrail structures. The handrail structures are arranged on the two sides of the upper portion of the footpath structure, and the footpath structure is formed by arranging a plurality of trussstructures. Each truss structure is a cubic or cuboid structure composed of twelve rod pieces, eight vertexes are each connected with an inclined rod, and the eight inclined rods are connected at thecenter of the truss structure. And the rod pieces, the rod pieces and the inclined rods, and the inclined rods are connected through the disc nodes. By the adoption of the space truss structure, vertical and lateral bidirectional overall rigidity is improved, a problem of instability outside a pressed surface of each handrail structure is solved, the rod pieces are evenly stressed, the rod piecesare connected through the disc nodes, and the strength of the nodes is effectively improved. The invention relates to the technical field of bridge construction.
本发明公开了通过圆盘节点连接的空间网架轻钢步行桥及其施工方法，包括步道结构和扶手结构；所述扶手结构设置在步道结构的上部两侧，所述步道结构由多个网架结构排列而成；所述网架结构是由十二根杆件组成的立方体或长方体结构，在八个顶点处分别连接一根斜杆，八根斜杆在网架结构中心处连接；所述杆件之间、杆件与斜杆之间以及斜杆之间都通过圆盘节点连接。本发明采用空间网架结构，提高了竖向、侧向的双向整体刚度，解决了扶手结构受压面外失稳的问题，使杆件受力均匀，并且通过圆盘节点连接杆件，有效提高节点的强度。本发明涉及桥梁建筑技术领域。
