Nordbro are the sole distributor of the Unibridge system in the Nordic and Baltic region. Unibridge is designed and manufactured by Matière SAS, a leading supplier of steel and concrete constructions. Unibridge is a modern pre-designed modular steel bridge system. It is a simple, robust, and durable structure suitable for use in emergency situations and as a permanent bridge. Comprising of a minimum number of components the Unibridge can be deployed quickly to site and rapidly erected.
Bridges for one lane or more can be built as single or multi-span bridges in clear spans of up to 45m for Eurocode loadings. The bridge is constructed from prefabricated box girders units being 11.4m or 6.1m in length. The box units are pinned together. The girders are connected transversely with spacers which allows for the installation of a steel deck with anti-skid coating or a concrete deck casted in in-situ. The box girders come in three different heights (1m, 1.25m and 1.6m). Span and loading dictates which size of girder to use.
UNIBRIDGE IN THE NORDIC COUNTRIES
Nordbro have supplied Unibridge in a developed version to Trafikverket in Sweden and Statens Vegvesen in Norway. The main feature is a new type of decking which can be mounted from above resulting in shorter building time and safer work environment.
The Unibridge procured by Trafikverket has a certified H2 barrier system and a 2m wide external footwalk. The system has undergone bearing capacity surveys according to the Swedish TDOK 2013:0267.
All bridge connections are made with either pins or bolts. There is no need for on-site welding.
Unibridge can be either craned in position or launched across the gap.
Unibridge is designed to the Eurocodes.
The bridge is designed for 100 year design life with a fatigue life of 1,000,000 cycles of the appropriate Eurocode vehicle.
Unibridge can be supplied with barriers approved for class H2 according to EN1317.
The bridge can be built with an anti-skid coated steel deck or with a concrete deck casted in-situ.
Unibridge can be supplied with a footwalk on one or both sides.
Unibridge shows great flexibility and can be used in several applications. In addition to road bridges, Unibridge is ideal for railway bridges and pedestrian bridges.
