Single Lane Prefabricated Single Span Truss Bridge High Strength Q345b Material

Single Span Single Lane Prefabricated Steel Truss Bridge With High Strength Q345b Material

Description
Steel Bailey bridge is a type of portable, pre-fabricated, truss bridge. It was developed by the British during World War II for military use and saw extensive use by British, Canadian and US military engineering units. The steel truss girder bridge is composed of truss members. Although the steel truss girder bridge is mainly bent and sheared, the truss members are mainly subjected to axial forces.

Specification

A Bailey bridge had the advantages of requiring no special tools or heavy equipment to assemble. The wood and steel bridge elements were small and light enough to be carried in trucks and lifted into place by hand, without requiring the use of a crane.

Application

Our Steel Bailey Bridges have been shipped and erected world-wide and are designed to suit a range of applications and come in a variety of types dependent upon your specific bridge requirements.

Generally used for urban bridges or highway viaducts and overpasses with small spans

Reinforced concrete: medium and small span

Prestressed reinforced concrete: large span

Straight leg frame (door type) and slant leg frame: medium and small span

T-shaped rigid frame, continuous rigid frame: large span

Parts of the bridge
The basic Bailey bridge is made up of three main parts, the floor, the stringers and the side panels. The floor of the bridge is made up of a number of 19-foot-wide transoms (5.8 m) that run across the bridge. Across the bottom of these, forming a square, are 10-foot-long stringers (3.0 m). The bridge's strength is provided by the panels on the sides. The panels are 10-foot-long (3.0 m), 5-foot-high (1.5 m), cross-braced rectangles. Each weighs 570 pounds (260 kg), and can be lifted by six men.
