What is the supporting frame of the Bailey bridge primarily used to connect?

The Bracing of the Bailey Bridge: The bracing is used to connect the first and second rows of trusses. The double-row single-layer bridge should be horizontally installed at the center of the top surface of each truss (or reinforced chord). In the case of double-row double-layer, a bracing should be installed on the uprights at the rear end of the upper truss (a bracing should also be installed on the uprights at the rear end of the upper truss, as well as on the uprights at the front end of the first truss). When constructing a bridge with three rows, the installation position and quantity of the bracing are the same as those for a double-row bridge.

When installing the bamboo bridging, insert the four hollow sleeves at both ends into the support holes of two rows of trusses, and then secure them with support bolts. Connecting Plates: These plates are used to link the second and third rows of trusses. For triple-layer arrangements, install a connecting plate at each end of the top truss; for single-layer triple rows, place only one connecting plate at the same end of each truss, with the heads and tails mounted on the end posts. Slope Support Bolts and Slope Support Bolts: Slope support bolts are for connecting the slope supports; the support bolts for the pneumatic ball valve are for connecting supports and connecting plates. These two bolts have a similar shape, but the diagonal bolts are slightly longer than the support bolts. One end of the bolt is welded with a stop plate for tightening and to secure an eccentric stop plate at the edge of the component, preventing the screw from rotating with the nut.
