ABSTRACT:
There is disclosed a beam structure for supporting a floor or roof. The beam is of V-shape cross-section, defining a lower apex and two upstanding side wings formed of wafer boards joined together at the apex by a coating of resin, in which is embedded, between the panels, a continuous tension-resisting cable. Compression-resisting strips are secured to the outside of the panels along their top edges. These strips are also made of wafer boards and serve to receive screws for securing the beam to the underside of the floor or roof.
