Alternating V-truss roof system and method of erection

摘要

A roof supporting structure and method of erecting such structure, the structure comprising a series of spaced apart rafters lying in parallel relation with a series of V-truss units extending between the rafters in parallel relation at spaced apart intervals to define rows of V-truss units supported at their opposite ends on the rafters, the V-truss units in a given row lying in alternating relation with respect to the V-truss units in the next adjacent row, the ends of the V-truss units in one row being interconnected with the adjoining ends of the V-truss units in the next adjacent row so that horizontal forces will be transmitted jointly by the V-truss units in adjacent rows. Modified V-truss units may be provided at the ends of alternate rows to further enhance the horizontal load supporting capability of the structure, the modified V-truss units additionally serving to mount the wall panels of a building utilizing the roof supporting structure. Girt members may be provided at the ends of the rows between the rows containing the modified V-truss units to provide continuity of support for the wall panels.
