Important results from the project
The project showed that birch plywood can replace steel in frame corner joints, reducing environmental impact and simplifying prefabrication and assembly. Full-scale tests showed that glued joints were 27% stronger than mechanically screwed joints. Other important results include improved analytical models and optimized gluing processes that can be used in other construction-related projects. A variant of the new solution has also been tested in a first-of-its-kind construction project.
Expected long term effects
The project has shown the participating parties that it is possible to develop new wood-based joint solutions that can also work on a commercial scale. In terms of materials and construction, it is a success and also in the current production setup a simplification compared to the current setup. The staff at the company that tested the solution in a sharp project believe that the system is lighter and easier to assemble than the corresponding available system.
Approach and implementation
The project design has worked well in most of the work packages. Most of these could be carried out as planned. The plan with small lab experiments as a basis for larger tests has proven to be successful. The work package on production technology has been partially delayed due to high production workloads at the companies. A larger experiment with a demonstrator has been started but will not be completed during the project period.
