What Are The Main Requirements For Installing The Bridge Deck Of The Bailey Bridge?

When installing the bridge deck of the Bailey bridge, the four hollow sleeves at both ends are inserted into the support bracket holes of the two rows of trusses, and then secured with support bracket bolts. Connection plates: Connection plates are used to connect the second and third rows of trusses. When there are three rows of double-deck, a connection plate should be installed at each end of the upper trusses; when there are three rows of single-deck, only one connection plate should be installed on each truss of the same side at each end, and the connection plates at the head and tail sections should be installed on the end columns. Bailey bridge diagonal brace bolts and diagonal brace bolts: Diagonal brace bolts are used to connect the diagonal braces; the support bracket bolts are used to connect the support bracket and the connection plate. These two bolts have similar shapes, but the diagonal brace bolts are slightly longer than the support bracket bolts. One end of the bolts is welded with a stop plate, which is used to clamp the eccentric stop plate against the component edge when tightening the bolt to prevent the bolt from rotating with the nut.
