Simple Steel Modular Footbridge With Single Lane Long Life

PB100 Modular footbridge Description:

Modular footbridges are portable steel bridge have been widely used in various fields, its most important feature is to achieve a variety of spans, bear carrying capacity, light and handy components, easy to dismantle and strong adaptability can be quickly completed with simple tools and manpower.The surface protection can be paint or hot-dip galvanized.

Similar to other modular bridges, steel modular footbridges are assembled using pre-engineered components that are manufactured off-site. These components are typically steel trusses, decking panels, handrails, and other necessary structural elements. The prefabrication process allows for efficient manufacturing, quality control, and quick on-site assembly.

The Importance of Bailey Bridge Application on PB100 Modular footbridge

As compared to the general transportation and bridge construction, PB100 Modular footbridge have its uniqueness. PB100 Modular footbridges are characterized by the economical and small-scale to provide connectivity for villagers in remote rural areas. The bridges of PB100 modular bridge are only used as footbridge and has forbidden the use of vehicles and agricultural machinery to cross the bridge. In that respect, the design loading for PB100 Modular footbridges has usually taken as 3kN/m2 and is much smaller than those applied for conventional bridges.

PB100 Modular footbridge Origin:

As the requirement on loading was smaller, the structural members of the bailey panel could be re-designed to a lighter weight, meeting its needs on economic, transportation, construction and other means. With the premise of ensuring safety, PB100 Modular footbridge excels the conventional Bailey bridge limitations as mentioned and it has its unique advantage of application in the PB100 Modular footbridge projects.

Upon years of discussion and collaboration, PB100 Modular footbridge has applied the advantages of Bailey bridge and optimal choice of material in its projects. EVERCROSS team have been entrusted to develop and design a light-weighted PB100 Modular footbridge. The bridge design has been given due considerations to the demand of function, natural environmental condition, technical feasibility, material transportation and cost etc.

PB100 Modular footbridge Introduction

Modular footbridge is a kind of light-weighted footbridge constructed from fabricated steel. It is composed of the load-bearing bailey panels, the minor load carrying transoms (floor beams), decks, other support members. The construction is simple by using standardized prefabricated components under a reasonable budget control.

 




PB100 Modular footbridge Features

1. High strength and big stiffness, relative to the concrete bridge can be reduced trabecular high and self-respect
2. Due to the steel isotropic, quality of a material is uniform and modulus of elasticity, that make steel bridge in the working condition and calculation compared with the assumption
3. Modular footbridge generally prefabricated in factory, site assembled by pins and bolts; the construction period is short, processing convenient and not affected by seasonal effect.
4. Modular footbridge is suitable for industrialized manufacture and very convenient to transport.
5. Modular footbridge is easy to repair and replace, long lifetime, material can be recycled.

Steel Trusses: The main load-bearing elements of a steel modular footbridge are the steel trusses. These trusses are designed to support the weight of pedestrians, cyclists, and other loads while providing structural stability to the bridge.

Lighting: Footbridges can incorporate lighting features to improve visibility and safety, especially during nighttime use. This may include architectural lighting integrated into the bridge structure or dedicated lighting fixtures along the handrails or deck.

Corrosion Resistance: Steel footbridges are typically treated with protective coatings or galvanized to enhance corrosion resistance. This ensures the longevity of the bridge and reduces maintenance requirements.

PB100 Modular footbridge Scope of Application

The erection of the bridge could be carried out in a speedy way as only manual labor and simple machinery are required. It is a versatile design and can be used widely as a footbridge in rural and mountainous areas.

In principle, the footbridge is designed for pedestrians and livestock uses and not for vehicles or agricultural machinery. Two standards of bailey footbridge roadway width, which are 1300mm and 1500mm, measured from the two truss panel centers (also defined as clear width of 1250mm and 1450mm respectively) have built and used as shown in figure. The 1500mm width design is more suitable to places where the need of free passage by livestock is required. The clear width of the bridge should not be larger than 1500mm and this could prevent the abused use by vehicles and agriculture machinery by overloading it.

Mixture form to erect all kinds of PB100 Modular footbridge

Temporary Bridges, Emergency Bridges and Fixed Bridges.
Using the bridge equipment, the suspension bridges of varied span can be erected.
The bridge has the advantages of few components, light weight and low cost.
Modular footbridge requires no special tools or heavy equipment for construction, the bridge elements are small enough to be carried in, and the bridge is strong enough to carry. It is considered a great example of military engineering.

PB100 Modular footbridge Competitive Advantage:

Light Structural Design:

Standard bailey panel structure is the basics of PB100 Modular footbridge. A single bailey panel should have weight less than 120 kg and length 2 meters. The light-weighted design allows its application in PB100 Modular footbridge projects. It also lowers the cost and prevents excessive waste of resources, ensuring the economy and sustainability of PB100 Modular footbridge construction.

Convenient Transportation

PB100 Modular footbridge usually locate in mountainous and rugged terrain. The transportation condition is

often remote and rough while manual labor are employed for conveying building materials and tools to

site. The light-weighted components of PB100 Modular footbridge can be easily handled manually and assembled

on site.

Moderate Construction Difficulty:

The bridge structure and its components of PB100 Modular footbridge are simplified and standardized. Only a small number of simple tools and machinery are required in its construction. As a result, the requisition of a relatively large number of skilled personnel on site is not necessary. In the circumstance, it allows a larger number of participants to involve in the project and the core values of PB100 Modular footbridge activities could be realized.

Good Durability

PB100 Modular footbridge employs steel open sections, preventing the accumulation of rainwater and dust. Combined with the application of zinc galvanization on the overall structure to prevent the steel from rusting, durability can be improved. Besides, this avoids river pollution from the application of traditional anti-rust paint.

Long Span

Bailey bridge has a longer span than the gabion bridge, thus, a smaller number of piers is required. Disturbance on the riverbed by excavation could be minimized and the effective flow of the river will not be hampered to a greater extent.

Simple structure

Standardization of prefabricated components

Controllable cost

Fast construction speed
