Installation of various support frames of Bailey Bridge

Bailey steel Bridge plays an irreplaceable role in the construction of traffic and flood fighting. The main structure of the bridge is composed of truss units, truss dowel, reinforcement chord, truss bolt, chord bolt, etc. The main structure is connected by a 3-meter-long truss with a pin, located on both sides of the driveway, and the truss is connected with the beam, and each truss is equipped with two beams; The bridge deck is laid at both ends of the bridge, and the end columns are arranged at both ends of the bridge. The main truss is supported on the bridge and the supporting plate by the end column, and the bridge and the embankment can be connected by the approach bridge. The whole bridge is equipped with inclined support, wind tie rod, support frame, connecting plate and other connecting parts, so that the bridge forms a stable spatial structure.

The trusses of Bailey Bridge were assembled at the time of installation, with one end of the trusses placed on the rock and the other end on the temporary cushion wood. The yin-yang head of the truss piece is consistent, put the first beam behind the front vertical rod, put the two rows of holes on the bottom surface of the beam into the bolt nails on the lower string beam backing plate of the two truss pieces, and clamp the beam fixture, do not tighten it temporarily. Install the diagonal support on the beam and tighten it again. The Beret bridge should install a diagonal bracket on the front part of the truss beam, and install a beam behind the front end of the second part of the truss vertical rod, which should be gently clamped with a beam clamp and not tightened temporarily.
