What is the structure of the beret?

The Bailey piece is welded by upper chord, lower chord, vertical chord and oblique chord. The ends of the upper chord and the lower chord are provided with male and female connectors, and the connectors are provided with pestle connecting pin holes. The chord () of the Bailey piece consists of two 10 channel steels (back to back). On the lower chord, there are many steel plates welded with round holes. There are bolt holes in the upper chord and the lower chord, which are used to connect the reinforced chord and the double-layer truss. There are also four bolt holes on the upper chord for connecting the support frame, and the two holes in the middle are used for connecting the same double-row or multi-row truss. Two holes near both ends are used for the connection between nodes. When multiple rows of berets are used as beams or columns, the joint between the upper and lower berets must be reinforced with support frames.

There are four beam pads on the lower chord with tenons to fix the position of the beam on the plane, and there are also two oval holes on the channel steel web at the end of the lower chord for connecting the wind-resistant tie rods. The vertical rods of berets are all made of 8# I-steel, and there is a square hole on the side of the vertical rod near the lower chord for the beam clamp to fix the beam. Bailey material is 16Mn, and each frame weighs 270kg.

"32 1" steel bridge is an assembled highway steel bridge, which is characterized by light weight, convenient disassembly, strong adaptability, rapid construction and simple tools and manpower. It is suitable for five kinds of loads such as automobile-10, automobile-15, automobile -20, crawler -50 and trailer -80. The clear width of the bridge deck carriageway is 3.7m, which can be combined into a variety of span simply supported beam bridges ranging from 9m to 63m, and can be used to build a continuous beam bridge.
