Abstract
A readily erectable and/or demountable (and re-erectable) building structure comprising a plurality of arch frames in vertical planes extending transversely of and spaced apart longitudinally of the building structure, each frame being provided with retainer means retaining the longitudinal beaded edges of flexible strip roofing material. The retainer means are of groove-like or channel-like form to receive the longitudinal beaded edges slidingly therein. Preferably two strips are provided between each pair of neighbouring arch frames such that when in position they each extend across the space between the two arch frames of each pair with the strip's width and length dimensions directed respectively longitudinally and transversely of the building structure (and such that a gap is provided between the adjacent strip ends in the structure's roof), the strips being tensioned in the direction of their length dimensions (i.e. transversely of the building structure). Preferably each strip has a shape in its unstressed state such that when tensioned in the direction of its length dimension it adopts a configuration that is concave to the exterior of the building structure.
