The chord and web members may be made of solid wood, Oriented Strand Board (OSB) Laminated Veneer Lumber (LVL), Waferboard or Veneer. The wooden beam is made of upper and lower chord members and two planar web members all interconnected by means of mechanical and adhesive secured joints. The overall outline of the section shape of the fabricated wooden beam is similar to standard lumber and can be made to fit the same standard dimensions available on the market or any other dimension, allowing for easy assembly with existing apparels and equipment. Chord members are extended by a finger jointing method; longitudinally extending grooves are provided on each side of a chord member, near an edge. Web members have their ends provided with a tongue shaped as to substantially fit in the chord members grooves.

L'invention porte sur une poutre de bois constituée de deux ailes séparées par deux membrures d'âme formant un rectangle avec les deux ailes. Les ailes et les membrures peuvent être faites de bois massif, de panneaux de copeaux orientés (OSB), de bois de placage lamellé (LVL), de panneaux à grandes particules ou de bois de placage. La poutre de bois est constituée d'une aile supérieure et d'une aile inférieure et de deux membrures d'âme planes interreliées par des moyens d'assemblage mécaniques et collées. Le pourtour général de la forme de section de la poutre de bois assemblée est semblable à celui du bois d'oeuvre standard et peut être configuré pour correspondre aux produits standards disponibles sur le marché ou avoir toute autre dimension voulue, permettant ainsi d'assembler facilement la poutre avec les matériaux existants. Les ailes sont aboutée par entures multiples. Des rainures se prolongent longitudinalement de chaque côté des bords. Les éléments de membrure présentent à leurs extrémités une languette formée de manière à s'emboîter dans les rainures des membrures.
