Abstract: Floor boarding is supported on a laminated core which comprises oblong panels of wood boards. The boards extend longitudinally and transversely, in recurrent patterns. The core is strengthened notably where the boards of the panels extend transversely. The strengthening is provided by edge fillets extending longitudinally. Step-like joints are provided for this purpose, between the laminated edge fillets and boards. One of each part of laminated fillets is made of hard-wood.
