What Should Be Paid Attention To When Using Reinforcing String For Bailey Bridge Support Frame

Bailey Bridge supports: Supports are used to connect the first and second row trusses. Double row single deck Bridges with horizontal supports mounted at the center of the top surface of each truss (or stiffening string). In the case of double rows and double layers, in addition to bailey frame installed on the top surface, a support frame shall be installed on the rear end of the upper truss (and one support frame shall be installed on the front end of the first truss). When erecting a three-row bridge, the installation position and number of bailey frames should be the same as that of a two-row bridge.

To install bailey plate, the four hollow sleeves at both ends are inserted into the support frame holes of the two rows of trusses, and then fixed with the support frame bolts. Connecting plates: Connecting plates are used to connect the second and third row trusses. When there are three rows of double layers, a connecting plate shall be installed on each end pole of the upper truss; When there are three rows of single layers, only one connecting plate shall be installed on the vertical rod at the same end of each truss, and the head and tail segments shall be installed on the end column. Berley bridge diagonal bolts and diagonal bolts: Diagonal bolts are used to connect diagonal bolts; Pneumatic ball valve bracket bolts are used to connect bracket and connecting plate. The two bolts are roughly the same shape, but the diagonal bolts are slightly longer than the support bolts. A baffle welded to one end of the bolt is used to fasten the eccentric baffle to the edge of the member when tightening the bolt so that the bolt does not turn with the nut.
