Long Span Metal Structure Prefabricated Pedestrian Bridges Overcrossing River Footbridge

Long Span Metal Structure Prefabricated Pedestrian Bridges Overcrossing River Footbridge

Description

Pedestrian bridges, like any other bridge, must be long enough to clear the obstacle which is to be crossed and high enough not to interfere with whatever passes beneath the bridge. However, the access route onto the footbridge is often much different from what is familiar to the designer of a highway bridge: there is no necessity for a gentle horizontal alignment (indeed the preferred route may be sharply at right angles to the span). Structural continuity is therefore less common. The principal span is often a simply supported one.

Specification

History
First bridges in history were pedestrian bridges and they were made of wood. Ancient Rome started making stone bridges in the 2nd century BC over the Tiber River. Some of these ancient stone footbridges with arches still stand today. One of them is Ponte Fabricio which was built in 62 BC and it still has some of its original materials. Today, modern footbridges are made of wood, rope, metal and concrete.

Design
Design of pedestrian bridge normally follows the same principles as for other bridges. However, because they are normally significantly lighter than vehicular bridges, they are more vulnerable to vibration and therefore dynamics effects are often given more attention in design.
To ensure pedestrian bridges are accessible to disabled and other mobility-impaired people, careful consideration is nowadays also given to provision of access lifts or ramps, as required by relevant legislation.

Features
The width of a pedestrian bridge is usually quite modest, just sufficient to permit free passage in both directions for pedestrians. Occasionally the bridge will have segregated provision for pedestrians and cyclists, in which case it will need to be wider. Parapets are provided for the safety of both the pedestrians and traffic flow. Pedestrian bridgeS over railway lines are required to have higher parapets and be provided with solid panels directly over the rail tracks.

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.
