Line

In the courtyard of the Bern University of Applied Sciences in Biel there is an endurance test stand with the new TS3 technology and the world's first frontally glued balcony. This clearly demonstrates the new possibilities for timber construction.

The Project

The new Timber Structures 3.0 technology (TS3) bonds timber components made of solid wood, glulam or cross laminated timber on the front side. This means that point-supported, multi-axis load-bearing panels or tiled slabs can be created in any shape and size. This opens up constructive and design worlds that were previously inaccessible to timber construction.


As part of a CTI project in collaboration with the Bern University of Applied Sciences and the ETH Zurich, the endurance test stand was erected using TS3 technology. The endurance test stand is an important step in the process of the approval test for the European and American markets.


The Design

The 7.5 x 7.5 m, point-supported, two-axis load-bearing floor slab consists of eight 2.5 m wide and 3.8 m or 1.8 m long, 24 cm thick cross laminated timber panels, which were joined together by adhesive casting. The 6.0 x 6.0 m grid is supported by four 5.0 or 6.5 m long screw foundations. Together with the two 24 cm thick pendulum columns, this is shown by the TS3 system: columns, slabs, finish!.


The challenges

The greatest challenge was the precise bonding of the load-bearing floor slab, the cantilevered balcony and the folding supporting structure in the roof in pouring rain. With stone blocks weighing twelve tons or a continuous surface load of 3.3 kN/m2 , the construction is now being put through its paces. 

Building data: 

- Cross laminated timber 112m²

- Round wood supports 24 cm diameter 2 pieces  

- Screw foundations 4 pieces 

- roof sealing  

- Stone blocks 36 pieces or 12 tons 


Services Timbatec/TS3:

- Feasibility study and preliminary project  

- Grouting of joints with TS3 technology
