More durable steel construction with new connection technology
The carbon footprint of the construction sector can be reduced by reusing building materials, but the reuse of welded steel assemblies in particular can be difficult. At HAMK, we address this challenge by developing innovative connection solutions for steel trusses.
The carbon footprint of the construction sector can be reduced through the circular economy by reusing building materials. Keeping materials and products in circulation for as long as possible maximises the use of existing resources. However, in steel construction, the use of trusses and especially their welded joints, for buildings, masts, road bridges and signposts, makes it difficult to reuse parts.
In MechJoint research project, we develop truss connection solutions and their manufacturing methods that allow the connections to be made without welding, enabling quick dismantling and reuse of steel truss structures. The solutions that promote circular economy will provide more environmentally sustainable alternatives to existing technologies. In addition, the transport in parts and the efficient assembly method made possible by the connection technology improve competitiveness and reduce construction costs.
We carry out the research in collaboration with LUT University, University of Coimbra and Fraunhofer Institute of Laser Technology. The project also involves a large number of companies – SSAB Europe, Stalatube, Weckman Steel, Ukko Works, Suomen Putkilaser, Würth, Linjateräs, Next Inox and Aerial, and Finnish Constructional Steelwork Association.
MechJoint project will run from 1.3.2025 to 31.8.2027. It gets funding from Business Finland.
