A cikkben azt a CLT technológiát mutatják be újdonságként, amit mi idehaza már 5 éve több mint 8 projektünkben használtunk már. Jó látni, hogy valamiben mi járunk élen a "fejlet nyugat" előtt.
Researchers at the University of Stuttgart have successfully tested a timber-concrete floor system designed to offer the strength and flexibility of reinforced concrete while dramatically reducing concrete use.
The full-scale UniversalTimberSlab demonstrator measured 9 × 5 meters (29.5 × 16.4 ft) and was just 36 cm (14.2 in) thick—comparable to a reinforced-concrete slab designed for an equivalent span and load.
During a public demonstration in Remscheid, Germany, the team placed 20 metric tons on the slab in addition to its own weight. Maximum deformation measured just 12 mm, while its natural frequency exceeded 8 Hz, satisfying the project’s deflection and vibration targets for multi-story buildings.
The system uses prefabricated glued-laminated timber segments arranged so their fibers follow the structural forces. A patent-pending segmentation method also allows complex or irregular floor shapes without requiring load-bearing partition walls or deep supporting beams.
According to the researchers, it requires approximately two-thirds less concrete than a comparable reinforced-concrete slab. Its compact design can also reduce structural height by 30–70 cm compared with conventional post-and-beam timber floors.
The first planned application is a three-story, 1,400-square-meter mixed-use building in Oberkochen, Germany.
Could timber eventually replace most concrete floors in large buildings?
