Load Action in The Transverse And Vertical Directions Of The Bailey Bridge

Bailey bridge should be connected before hoisting, Bailey beam support connection commonly used diagonal brace, support frame, wind tie rod, beam fixture, truss bolt, string bolt, diagonal brace bolt, strut bolt and other components. The exact position of each set of Bailey beams should be released on the I-beams on both sides of the Bailey bridge before hoisting, and the artificial auxiliary crane should be accurately in place. The Bailey beam is placed on the transverse distribution beam and connected with the transverse distribution beam by a U-shaped buckle.

Under vertical load, the section of the main beam only has bending moment and shear force, which does not produce axial force, and the support bears the vertical force rather than the horizontal force. The beam jig cannot bear the large upward load, so when the beam is clamped with the jig, it is strictly prohibited to jack up the beam. Arc supports are welded under the curved flange, such as the height difference between the bridge deck and the road surface is large, and two or more sections of the lap plate can be connected.
