In the Austrian Tyrol, a 650m2 cross laminated timber panel was created in two days using TS3 technology. This is a world record: it is the largest continuous CLT panel.

The project

Markus Handl Beteiligung GmbH is an Austrian family business based in the Tyrol. With the company's focus on its homeland, it is natural that Handl GmbH relies on wood as a natural building material for the new construction of the large-scale project.

    

For the new production building in Vorarlberg, Austria, the panel faces were pre-treated with the TS3 special primer at Binder's CLT plant in Unternberg and immediately afterwards sealed and segmented. The 3.5-meter-wide slabs, some of which weighed over five tons, were loaded just in time and driven directly to the construction site in Pians by escort vehicle.


The construction

A falsework was created for the assembly. TS3 ensured the flexurally rigid connection of the individual 240 mm cross-laminated timber panels using Henkel's patented potting technology with 2K polyurethane adhesive. The column head reinforcement Spider from Rothoblaas was installed above the columns in a 7 x 7 meter grid. X-Fix from Schilcher Trading & Engineering GmbH were used as assembly aids.


The challenges

Until now, the TS3 joints were formed in parallel. These were each elaborately sealed on the underside of the slab. In this project, a V-shaped joint was formed for the first time. This requires less casting resin and simplifies the process, as sealing can be dispensed with on the underside.
