With has installed a new joinery system. The timber construction company Flück commissioned Timbatec and TS3 to construct a wooden working platform for the processing of the cut timber elements.

The Project

The new working platform of Flück Holzbau AG in Wangen near Dübendorf is 15 meters long, 7.5 meters wide, 36 centimeters thick, weighs 18 tons - and consists mainly of wood. It is used for processing the wooden elements from the newly installed TW-Agil 3000 joinery machine, which has an inlet width of 3000 millimeters.


The challenge 

The enormous spans combined with the high payloads posed a great challenge for the timber construction. The platform consists of three cross laminated timber panels, which have been glued together using TS3 technology to form a large panel. In order to relieve the adhesive pull side and minimize deflection and vibration, the panel was eccentrically pre-tensioned with tie rods.  


The enormous spans combined with the high payloads posed a great challenge for the timber construction. The platform consists of three cross laminated timber panels, which have been glued together using TS3 technology to form a large panel. In order to relieve the adhesive pull side and minimize deflection and vibration, the panel was eccentrically pre-tensioned with tie rods.  

The height of the platform beam, which is stretched over the entire 15 meters, was limited. The reason: on the lower side the feeder for the panel processing system should be located, on the upper side the beam should not protrude too high above the platform so that the stacker can remove the packages with the wood.


The height had to be limited to 700 millimeters. For this reason, a high-performance beam made of beech veneer plywood was used. However, the deformations were too high. For this reason, two steel tie rods were inserted into the beam in the shape of a fish gutter and pretensioned. Thus, on the one hand the girder could be raised, on the other hand the girder became stiffer and the deformation smaller.

- TS3 cross laminated timber panel 40 m³

- Construction beech veneer laminated wood 3 m³

- Prestressing steel Swiss Gewi 800 kg

- Platform area 110 m²
