Abstract (en)
The beam comprises right-angled cuboids (4) which are glued together, and which are each formed from two right angled triangular segments which are also glued together. The segments are formed be making radial cuts into a tree trunk. The cuboids are glued together so that the growth rings in the grain of the wood extend in a roughly longitudinal direction of the beam. The trunk may first be moulded into the shape of an octagon, before the radial cuts are made. Both longitudinal sides of the triangular segments may also be in the radial direction.
