ABSTRACT:
A building structure comprising spaced rows of upright frame members formed of metal reinforced uPVC extrustions each joined by an eaves beam, and a plurality of extruded roof bars connecting said rows, selected roof bars being metal reinforced, and means to connect together the frame members and selected roof bars so as to provide a rigid joint at each connection, thus providing a structure such as a conservatory with one or more Portal frames. The joints are preferably bolted with at least two bolts, and the roof bars are of inverted U-shape, and a metal ridge bar interconnecting their apices; preferably projections on the ridge bar extend into the members of the roof bars and are bolted to the metal reinforcement. Preferably, metal eaves brackets are also provided.
