A kind of truss-like beam-arch composite bridge of double deck full steel structure is the utility model is related to, as shown in figure 1, it is wrapped
Include the arch rib wind brace between truss-like girder 10, the truss type arc rib being erected on girder 10 20, two truss type arc ribs 20 of setting
30 and the double deck 40 that is arranged between girder 10.
Wherein, the girder 10 includes girder top boom 11, girder lower boom 12 and is arranged on girder top boom 11, master
Girder web member 13 between beam lower boom 12, the tiled serpentine of girder web member 13 is set, with girder top boom 11, girder lower edge
Bar 12 forms truss structure.The girder 10 uses truss-like, undertakes part deadweight and bridge floor mobile load, remaining is by suspension rod by bridge floor
Load passes to arch rib 20, and the horizontal thrust of arch rib 20 is then balanced by the pulling force of girder 10, and the girder 10 is in the group
Main bearing member is used as in zoarium system, takes full advantage of the deck-molding advantage of double deck 40.
The arch rib 20 includes arch rib top boom 21, arch rib lower boom 22 and is arranged under arch rib top boom 21, arch rib
Arch rib web member 23 between chord member 22, the both ends of the arch rib top boom 21 are extended respectively to 101 at the abutment pier bearing of both sides, institute
The both ends for stating arch rib lower boom 22 are extended respectively to 102 at the main pier bearing of both sides, and 102 are located at two at the two main pier bearings
101 inner side at abutment pier bearing；The tiled serpentine of arch rib web member 23 is set, with arch rib top boom 21, the structure of arch rib lower boom 22
