Hybrid-Flatslab with screw connection

The Hybrid-Flatslab (HYB-FS) with screw connection consists of the concrete level above and the cross laminated timber surface below. This cross laminated timber surface can be produced in a wide range of visual qualities. Depending on the building requirements, a wide variety of cross-layer structures are possible within the cross laminated timber level. This combination allows the flat slab to be stretched up to 8.20 m with a panel width of up to 3.00 m.
