German bridge of concrete and wood composites

As part of the safety expansion of the expressway between St Veit South and North in Germany, new bridges had to be built. One of these is a combination of wood and concrete composites. Source: Timberbiz

The Hasslacher group, together with Asfinag, is developing an innovative solution for the Klagenfurt expressway. One of these bridges will be a wood-concrete composite bridge.

The wooden component is 21 m long, 1 m thick and has a width of almost 4 m.

The width is made of 15 individual glued laminated timber elements, a so-called composite component according to EN 14080. It contains a total volume of 82m³ of glued laminated timber and stores about 70 tons of CO2.

In order to be able to monitor the wood moisture, a network of sensors was woven across the entire timber structure, the data of which can be read out online at any time via a monitoring system.

The Hasslacher group specializes in special glued laminated timber components. Elements up to 52 m long and weighing up to 60 tons have already been produced.

The Hasslacher group is an innovation leader in the field of intelligent and integrated system solutions for modern timber construction.
