Abstract

L'invention concerne une poutre en bois (1) constituée de deux éléments de poutre (3 et 5) lesquels sont préférentiellement formés par deux pièces en bois (4 et 6) juxtaposés dans le sens longitudinal. Les éléments (3 et 5) de la poutre en bois (1) sont reliés entre eux par des vis (7 et 14), le partie centrale A de la poutre en bois (1) étant dotée de vis (7) qui présentent une orientation perpendiculaire à l'étendue longitudinale de la poutre en bois (1) et les parties terminales (B, C) de la poutre en bois (1) étant dotées de vis (14) qui présentent une orientation inclinée par rapport à l'étendue longitudinale de le poutre en bois (1). Dans lesdites parties (B, C) de la poutre en bois (1), les vis (14) à orientation inclinée sont orientées de telle manière que leurs extrémités supérieures sont plus éloignées du plan transversal central (15) de la poutre en bois (1) que leurs extrémités inférieures lorsque la poutre en bois (1) est placée dans sa position d'utilisation.
