A kind of novel steel truss bridge inspection device
Technical field
The utility model relates to bridge inspection vehicle technical field, specifically a kind of novel steel truss bridge inspection device.
Background technique
Steel truss bridge refers to the bridge using truss as the main supporting member of superstructure.Steel truss bridge is generally by main bridge
Frame, upper and lower horizontal lateral bracing, portal frame and intermediate cross frame and bridge deck composition.In truss, chord member is composition purlin
The rod piece of frame periphery, including top boom and lower boom, connect the rod piece of upper and lower chord member web member, by web member direction difference again
Divide into brace and vertical bar.Plane where chord member and web member is just main truss plane.The bridge height of large span gantry is along across footpath direction
Variation forms curved-chord truss;Middle or small span is high using constant purlin, i.e., so-called flat string truss or straight string truss.
