The frame sections comprise at least a quarter circle male section with a continuous projecting tenon and a similarly shaped female section which is of 'U' section and locates on the tenon of the male section. These sections are joined to similar or straight sections. A mechanical connection is provided between sections and screw jacks and base plates are used to wedge the frame between substructural members. A screw fixed floating spigot joins the ends of the sections and the junction between inner and outer sections forms a groove for location of glazed or infill sheets etc.
