ABSTRACT:
This invention relates to a wooden beam built up of two chord members separated by two web members forming a rectangle with the chord members. 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.
