CA 2273139

An I-beam with a main beam body and a head at each end. The heads are symmetrical widthwise laterally of the beam body with each head having an outwardly facing side shaped to define two identical, longitudinally outwardly facing grooves. Each groove is shaped by longitudinally outwardly facing ribs and by transverse ribs at the free ends of the first mentioned ribs to define an opening into an undercut region inside the groove. The heights of the ribs are selected relative to the width of the grooves so that the height of the laterally outer rib of one beam fits into the height of the undercut of the groove of the other beam when the rib of one beam is installed in the groove of the other. The ribs in the grooves are shaped to support the rib of the head of one beam in the groove of the other when the beam bodies are at right angles. In an alternative design, there may be a third groove between the two outer grooves.
