How many aspects are included in the bridge deck system of Bailey

Bailey deck system includes beam, longitudinal beam, bridge panel, flange and so on.

Cross beam: The cross beam is equipped with 4 groups of buckle to limit the longitudinal beam part, both sides are welded with short columns to connect the throwing brace, and both sides have 3 concave eyes on the bottom edge. When installing the beam, insert the concave eye into the shear nails on the beam pad block of the belly rod of the column, so that the beam is in place on the column. The interval of the concave eye is the same as the spacing of the analysis frame, and after the beam is in place, the interval of the analysis frame is relatively fixed.

Beam fixture: composed of support rod, suspension beam and support rod; To hold a stationary beam. There is a convex head at the top of the support rod, and the convex head of the support rod is buckled into the vacancy of the beam pad during installation. The end of the suspension beam is hooked on the square hole circle of the column vertical rod, and then the rod (or spanner) is used to rotate the support rod so that it is locked and fixed. The beam jig can not bear a large upward load, so when the beam jig is clamped, it is strictly prohibited to use hydraulic jacks to lift up under the beam, and the beam is fixed.

Longitudinal beam: Longitudinal beam is divided into buckle longitudinal beam and no buckle longitudinal beam two kinds. Buttons are welded on the buckle longitudinal beams, built on both sides of the bridge floor, and the bridge panel mortises are placed in the middle of the buttons. Four of the buttons are provided with sealing holes, which are used to connect the edge materials and the bridge panel with the buckle longitudinal beams according to the holes. The unfastened longitudinal beam is built in the middle of the bridge without distinguishing the two sides.
