Type 200 Bridge Structure

The basic components of type 200 bailey bridge include trusses, reinforcement chord, diagonal brace, support frame, TR connecting beam, cross beam, wind tie rod, vertical wind hook, bridge panel, backlash plate, curb, positive end post, negative end post, support, support plate, truss pin, headless truss pin, safety ring, bridge floor bolt, wind hook bolt, beam bolt, chord bolt, etc. These components are combined in a specific connection to form a stable and strong bridge structure.

For some steel Bridges with longer spans, the method of reinforcing the staggered arrangement between the joints between the strings and the trusses is adopted to effectively reduce the inelastic deformation caused by the clearance of the pin holes. At the same time, the application of the pre-arch method greatly reduces the vertical deflection in the span of the bridge and improves the bearing capacity of the bridge.
