ABSTRACT:
A beam having flanges composed of wood pieces and a web consisting of a wire member bent alternately back and forth to extend between and being attached to the flanges at the bends. Each flange comprises at least two wood pieces which extend longitudinally of the beam and are joined together by gluing, at least one of the wood pieces having recesses in the surface joined with the other wood piece, which recesses are adapted to receive the bends of the wire member. The beam is manufactured in that recesses are arranged at regular intervals in a long wood piece, whereupon two such wood pieces provided with recesses are placed at a distance from one another corresponding to the distance between the flanges of the beam to be made, with the recesses in one wood piece exactly opposite to points situated halfway between the recesses in the other wood piece. Then the wire member bent alternately back and forth is placed with its bends alternately in the first and the second wood piece, whereupon an additional wood piece is glued on to the recessed side of each of the wood pieces.
