What Should Be Paid Attention To When Using The Inclined Stringers Of Bailey Steel Bridges?

The bearing plates are supported on a common sleeper. Smooth rollers (used to bear the weight of the bridge and reduce resistance at the start of movement) are set every 6 meters. Each smooth roller can bear a load of 60 kg. The height of the smooth roller is 19 cm when placed on the bearing plate, and 21.5 cm when placed on the bridge head plate. The bridge head plate is similar to the longitudinal beam.

The Bailey steel bridge rocking sample and rolling sample: used to stabilize the rollers and increase the ground contact area of the rollers, overcome the roller sinking, and quickly determine the position of the rocking and rolling. The Berthier steel bridge oblique stringer: used to make the reinforced stringer bridge pass smoothly from the rollers during the advance process. It is divided into male and female heads; installed at the ends of the stringer on both sides of the analysis frame, connected to the reinforced stringer with pins and the hook at the end of the oblique stringer. The difference lies in the I-beam steel plate in the bridge head restraint, which is 12 cm higher in the middle and the same height as the longitudinal beam (10 cm) at both ends to maintain the flat bridge surface. Welded arc support is welded under the curved flange. If there is a large difference in the bridge surface and the road surface, two or more bridge plates can be used, with cross beams supported in the middle, and the cross beams placed in the four support plates.
