The compact 200 panel bridge: The compact 200 panel bridge is
similar to the compact 100 panel bridge from their
appearance. The difference is its increased panel height to 2.134m.
It adopted the method of alternating joints
between Chords Reinforcement and the joints between panels. This
method can decrease inelastic deformation
caused by the oversized pinholes. Pre-arch method is used to
additionally cut down mid-span and vertical deflection to
a larger degree. Bolt-connected components use the orienting
sleeve- fixing method to increase accuracy of
connections. Shear is created in orienting sleeves and tension is
developed in bolts, which increase the usage life of
the bolts and ensure the safety of panel bridges. Wind resistant
brace is made to be composite type and is connected
to transom/girders to improve overall stability of panel bridges.
The part between supporting frame and panels is fixed through
bridging in order to prevent the whole bridge from side
bending. After the erection, there will be a pre-arched degree over
the span of the bridge. The compact 200 panel
bridge can be assembled into both single and double lane bridge, so
it broadens its application range. It is suitable for
the load designs of HS-15, HS-20, HS-25 and pedrail-50 etc.
It's consists of bailey panel (normal ,high shearing force),
transom (single lane, double lane), chord reinforcement, 1050 mm
steel deck and other components.
