Abstract
Abstract There is disclosed a system of fixtures for use with standard dimension lumber for constructing pitched roofs for residential or commercial wood frame structures including gabled roofs, hip roofs and more complex roof structures. One form of sheet metal fixture takes the uncut ends of a pair of two inch (nominal) thickness lengths of lumber and is so shaped that the two lengths of lumber are joined with the fixture and common nails at a selected angle corresponding to the desired angle between rafters at the peak of a gabled roof. Other disclosed fixtures are shaped to join a hip rafter with one or more common rafters or jack rafters. Similar fixtures are used to join valley rafters with jack rafters. Further plate fixtures secure the lower ends of rafters to the plate on top of the exterior wall frame without the necessity for an angle cut or bird's mouth cut in the rafter. The fixtures are shaped of sheet metal to join respective rafters at the proper simple angle or compound angle for a predetermined roof pitch; some fixtures such as the common rafter peak fixture are adjustable for several different pitches by slight bending of the top portion of the sheet metal fixture.
