A system for building steel framed structures (9,12) wherein a series of slots (2) and tongues (1) are punched in the various components that are required to make a wall (9) or truss (12), the slots (2) to position components precisely and the tongues (1) to secure them. The frames (9) or open web trusses (12) are thus able to be fabricated without the necessity of a jig or additional fastenings, allowing the fabrication to be carried out quickly and on site if desired. Also disclosed is a tongue (3) which is slit to it's base enabling the halves of the tongue to be bent in opposite directions and a securing bracket (Fig.8) for the system. |
