Deck Steel Box Girder Bridge Fabion Between Urban High Rise Modular Connecting Corridor Skyway

High Strength Segmental Box Girder Structural Formwork Bridges For Highway And Railway Projects

Description

The 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. A Bailey bridge has the advantages of requiring no special tools or

heavy equipment to assemble.

A steel box girder bridge is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises either prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section.

Specification

Steel box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although normally the steel box girder bridge is a form of beam bridge, box girders may also be used on cable-stayed bridges and other forms.

Construction
For steel box girders, the girders are normally fabricated off site and lifted into place by crane, with sections connected by bolting or welding. If a composite concrete bridge deck is used, it is often cast in-place using temporary falsework supported by the steel girder.

Either form of bridge may also be installed using the technique of incremental launching. Under this method, gantry cranes are often used to place new segments onto the completed portions of the bridge until the bridge superstructure is completed.

Application

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

Competitive Advantage
Reduces the slab thickness and self-weight of bridge
Cost effective
Greater strength per unit area of concrete
Quality assurance, as precast girders are made off-site

Our company

Our experienced team is focused on your steel bridge project's success, from start to finish. Our proven ability to identify and overcome design inconsistencies, potential problems with erection, and shipping obstacles results in the fabrication of structural steel that is right the first time, helping you avoid costly construction delays.

Proper project coordination and efficient delivery of the structural steel to your bridge project is a key factor in its ultimate success. This is what gives us the leading edge.

From material purchase and tracing, planning compilation, drawing detailing, production arrangement, quality inspection, to on-going painting, packing and delivering, we have separated department to strictly control process, quality and traceability, so that the perfect Bailey/Belay/Baley Bridge can be made.

Finally we would like to emphasize that not like other companies, nearly all machining parts and mechanical accessories are manufactured in our own shop as we have so many wonderful machines and workers inside. In this way, the quality, cost and delivery time can be ensured which eliminates other exterior factors’ influence.
