In Austria a timber construction is currently being built with a massive 650m2 cross laminated timber panel, which is a world record. TS3 technology makes it possible, this is a development by Timbatec together with the ETH Zurich and the Bern University of Applied Sciences. Source: Timberbiz
TS3 technology is a quantum leap: it frees timber construction from its small structures and makes it a real alternative to conventional reinforced concrete. TS3 is a process that can generate large areas from wood without the previously used beams. These large surfaces can replace reinforced concrete in most areas.
After 10 years of research by Timbatec with the ETH Zurich and the Bern University of Applied Sciences the process was developed using a two-component polyurethane casting resin. This resin joins the wooden elements rigidly together.
In the Handl project in Vorarlberg, Austria, the panel faces were pre-treated with the TS3 special primer at Binder’s CLT plant in Unternberg and immediately afterwards provided with sealing and segmenting strips.
The 3.5-metre-wide slabs, some of which weighed more than five tonnes, were loaded just in time and driven directly to the construction site in Pians in an escort vehicle.
The cross laminated timber boards are placed on the wooden supports with a grid of 7 x 7 metres. For the assembly, an additional empty scaffolding was also created.
An application technician can seal the joints with the two-component adhesive, which was specially developed for TS3. After only a few days, the scaffolding can be removed.
The result is the largest CLT panel in the world.
