Highway and railway dual-purpose bridge
The invention discloses a highway and railway dual-purpose bridge and relates to the technical field of bridge structures. The bridge comprises a plurality of steel truss girder sections connected ina longitudinal direction of the bridge. Each steel truss girder section comprises two main truss upper chords and two main truss lower chords. The two main truss upper chords are arranged in the transverse direction of the bridge at a preset first width interval, at least two main truss upper cross beams are connected between the two main truss upper chords, and highway bridge decks are laid on the main truss upper cross beams and the main truss upper chords. The two main truss lower chords are vertically arranged corresponding to the two main truss upper chords respectively; a plurality of main vertical rods are connected between each main truss lower chord and the corresponding main truss upper chord; at least two main truss lower cross beams are connected between the two main truss lower chords and vertically correspond to the main truss upper cross beams, two railway longitudinal beams are connected between every two adjacent main truss lower cross beams, the two railway longitudinal beams are spaced by a preset second width, and railway bridge decks are laid on the railway longitudinal beams and the main truss lower cross beams. The bridge is simple in structure, reasonable instress and good in economical efficiency.
本发明公开了一种公路铁路两用桥梁，涉及桥梁结构技术领域，包括多个沿桥梁纵向连接的钢桁梁节段，每个钢桁梁节段均包括：两根主桁上弦杆，其沿桥梁横向间隔预设的第一宽度设置，两根主桁上弦杆之间连接有至少两根主桁上横梁，主桁上横梁和主桁上弦杆上铺设有公路桥面板；两根主桁下弦杆，其分别竖直对应两根主桁上弦杆设置，每根主桁下弦杆与对应的主桁上弦杆之间连接多根主竖杆，两根主桁下弦杆之间且竖直对应主桁上横梁连接有至少两根主桁下横梁，相邻两根主桁下横梁之间连接有两根铁路纵梁，两根铁路纵梁间隔预设的第二宽度，铁路纵梁和主桁下横梁上铺设有铁路桥面板。本发明构造简单，受力合理，经济性好。
