Integral steel truss structure platform bridge and construction method thereof
The invention discloses an integral steel truss structure platform bridge. The integral steel truss structure platform bridge comprises a platform bridge main steel box girder, stiffening rib steel plates are fixed in the main steel box girder, flange cantilever steel boxes are fixedly connected with the two sides of the main steel box girder, platform bridge decks are laid on the flange cantilever steel boxes, diagonal web member steel boxes are fixed to the top of the main steel box girder, an upper chord steel box girder is fixed to the tops of the diagonal web member steel boxes, and a platform bridge canopy is fixed to the top of the upper chord steel box girder. According to the integral steel truss structure platform bridge, by arranging diagonal web member steel box trusses, the supporting problem of the platform bridge canopy is effectively solved, meanwhile, the diagonal web member steel box trusses serve as stress components, the size of the main steel box girder of the platform bridge is effectively reduced, and the spanning capacity of the platform bridge is enhanced; the platform bridge can be set as simply supported beams or continuous beams, and can meet the requirements of platform bridges with different lengths; and the platform bridge is of an integral steel box truss structure, pushing construction is adopted in place after integral construction is completed, the construction period is shortened, the appearance is attractive, and construction is rapid.
本发明公开一种整体式钢桁结构站台桥，包括站台桥主钢箱梁，所述主钢箱梁内部固定有加劲肋钢板，两侧固定连接有翼缘悬臂钢箱，所述翼缘悬臂钢箱上铺设有站台桥面板，所述主钢箱梁顶部固定有斜腹杆钢箱，所述斜腹杆钢箱顶部上固定有上弦杆钢箱梁，所述上弦杆钢箱梁上方固定有站台桥雨棚。本发明通过设置斜腹杆钢箱桁架，有效解决了站台桥雨棚的支撑问题，同时作为受力构件，有效减小站台桥主钢箱梁的尺寸，增强了站台桥的跨越能力。站台桥梁型可设置为简支梁或者连续梁，能够适应不同长度的站台桥梁的要求；站台桥本身采用整体式钢箱桁架结构，整体施工完毕后，采用顶推施工就位，节约工期，造型美观，施工快速。
