Pi-shaped truss web steel box-concrete composite beam bridge
The invention relates to a pi-shaped truss web steel box-concrete composite beam bridge. The bridge comprises box-type structure truss piece groups, a steel cross beam, an upper parallel connection, alower parallel connection, a shear nail group, a bridge deck slab and a wet joint bridge deck slab; each box-type structure truss piece group is formed by connecting a main truss web member with a main truss upper chord member, a pi-shaped main truss lower chord member and a connecting truss piece through a gusset plate; the truss piece groups are connected through steel cross beams, and inclinedweb members of the steel cross beams are connected with pi-shaped cross beam upper chords and pi-shaped cross beam lower chords through gusset plates. The pi-shaped cross beam upper chords and the pi-shaped cross beam lower chords are sequentially connected through the upper parallel connection and the lower parallel connection. According to the pi-shaped truss web steel box-concrete composite beam bridge, the structural strength, rigidity and stability are improved, design and construction are facilitated, and structural stress is more reasonable.
本发明涉及一种π型桁腹钢箱‑混凝土组合梁桥；包括箱式结构桁片组、钢横梁、上平联、下平联、剪力钉群、桥面板和湿接缝桥面板，箱式结构桁片组由主桁梁腹杆通过节点板连接主桁上弦杆、π型的主桁下弦杆，连接桁片形成桁片组；桁片组之间通过钢横梁连接，钢横梁斜腹杆通过节点板连接π型的横梁上弦杆、π型的横梁下弦杆；多片π型的横梁上弦杆、π型的横梁下弦杆通过上平联、下平联依次连接。本装置提高了结构强度、刚度和稳定性，便于设计与施工，使结构受力更加合理的π型桁腹钢箱‑混凝土组合梁桥。
