An inflatable building is made up of a framework which consists of a plurality of arches (61) interconnected by purlins such as eave purlins (62) and ridge purlins (63), the lower ends of the arch (61) being secured to ground or floor fitments (64). Each arch (61) can have two wall portions (67) and two roof portions (68) (although obviously a greater or lesser number of such portions can be provided). Junctions, such as eave junctions (65) and ridge junctions (66) can be made by manufacturing each tubular arch of individual tube lengths and joining them with connectors, but desirably each arch (61) is continuous and has an angle formed by shaping the material of the arch (61) during construction thereof, the arch (61) being secured to the purlin (62, 63) at the junction by tension means such as strapping, the whole framework composed of the arches (61) and the purlins (62, 63) and supporting a membrane on the inside or outside thereof. |
