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.
A building structure comprising a plurality of arch frames disposed in vertical planes extending transversely of the building structure and spaced apart longitudinally of the building structure, each frame being provided with retainer means for longitudinal beaded edges of flexible roofing material in the form of strips, characterized in that the lengths of two of said strips are in aggregate less than that required to extend continuously along a said arch frame, said two strips are slidingly received in said retainer means of a pair of neighbouring ones of said frames such that said two strips extend with their width dimensions directed longitudinally of the building structure across space between said pair of neighbouring frames and with their length dimensions directed transversely of the building structure in opposite directions away from a gap in the roof of the building structure between adjacent upper ends of said two strips, the bottom edges of said two strips remote from said gap are positionally fixed, and said two strips are tensioned in the direction of their length dimensions by adjustable tensioning means interconnecting the upper ends of said two strips and acting between said two strips in the general direction of their said length dimensions.
A method of assembling a building structure, said method including the steps of:
