Abstract: A support structure for forming eave corners on a hipped roof of a steel framed structure comprises a rectangular frame having two triangular sub frames tiltable along their adjacent diagonal sides. The inner corner of the rectangular sub frame is supported above the outer diagonal corner to form triangular planes coplanar with adjacent roof planes on each side of a hip line, the rectangular frame being cantilevered over the corner walls of the building to form an eave corner. The support structure may also be used to form internal or external corners on a verandah roof. A method for constructing hipped roofs on steel frame buildings is also provided.
