Wood technology - joinery and connections
Joint solutions for wooden frames are many: nailed, screwed, mortised, glued… they hold together building parts in both small and large structures. In this area, RISE helps companies and partners to develop new technology and to quality-assure products and productions.
The primary purpose of joints is to hold the construction together and bring loads down to the foundation. Sometimes they are performed in a factory to increase the degree of prefabrication and quality or on a construction site when the parts become too large or require accuracy. If they are visible, their appearance and functionality may be worth paying attention. A complete building is made of many joints and therefore the requirements set for entire buildings must be verified at a detailed level. At RISE, we help to develop and ensure that joint technology for timber structures meets current and future requirements, for example, we work with:
- Quality assurance of fasteners and joint processes for timber structures according to different standards,
- Fire resistance of structures made of LVL, glulam and CLT,
- Development of simple and fast tensile joints for CLT buildings,
- The effect of connections on the transmission of impact sounds and vibrations,
- Robust connections to avoid disproportionate collapse,
- Dismountable for circular buildings,
- Execution standard for adhesive joints performed on the construction site,
- Modeling of joints for better prediction of movements and dynamic properties in taller timber buildings exposed to wind-induced vibrations,
- Creep in glued joints,
- Fatigue strength of composite joints for wind turbine towers.
