Product introduction
Bailey Bridge Curb are generally used in 200-type steel bridges and GW D-type steel bridges to mark the edges of lanes. In order to ensure the safety of construction vehicles, a full-length I28 steel I-beam is set along the railing and along the bridge direction as a curb protection to prevent vehicles from falling.
The 200-Type Bailey bridge is similar to the 321-Type Bailey bridge from their appearance. The difference is its increased panel height to 2.134m. For some bridge with longer spans, It employed the method of alternating joints between Reinforcement Chords 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 Bailey bridges. Wind resistant brace is made to be composite type and is connected to transom/girders to improve overall stability of Bailey bridges. The part between braced frame and panels is fixed through bridging so as to prevent the whole bridge from side bending. After the erection, there will be a pre-arched degree over the span of the bridge. Besides it can be assembled into single-lane bridges. The compact 200 panel bridge can also be assembled into double lane bridge, hence it broadens its application range. It is suitable for the load designs of HS-15, HS-20, HS-25 ,HL-93 and pedrail-50 etc.
