What is Unibridge® ?
Unibridge® is a pre-designed and prefabricated modular steel bridge system. It is a simple, robust and durable structure suitable for use in emergency situations and as a permanent bridge. Unibridge® is a modular predesigned and prefabricated steel bridge system. It has been designed for international load classes and can be built in single lane or multi-lane road width. It uses either a steel deck system with anti-skid coating or concrete deck. All structural members are underneath deck level thereby avoiding the possibility of vehicle collisions with the structural members.
Unibridge® is constructed from prefabricated girders either 11.4m or 6m length. They are pinned end to end and connected transversely with spacers which allows for the installation of a steel deck with anti-skid coating or a concrete deck in-situ. The prefabricated girders are provided in three different heights (1m, 1.25m and 1.6m) and the span of the bridge dictates which girder to use:
|Bridge length||Span between bearings||Depth of box girder|
Multi-span bridges can be built to achieve bridge lengths >45.6m. As with single span bridges, Unibridge® multi-span bridges can be cantilever launched from the home bank to the far bank.
