A joint member or fishplate intended to join together two lengths of I-Section beams at an angle one to the other. The fishplate comprising two arms including a predetermined angle and joined by a central portion having an outwardly projecting block, the sides of which extend outwardly perpendicular to the axes of the respective arms. This enables the mating ends of the two beams to be cut perpendicular to their axes and when joined together by a fishplate, the bottom flanges of the two beams abut or nearly abut and the top flanges are separated by a distance, depending upon the angle at which the beams are being joined, and which corresponds to the length of the outwardly projecting block. The ends of the top flanges of the beams then contact the sides of the outwardly extending block to form a strong joint. |
