<p>A rapidly erectable building structure (10) includes a plurality of arches (12) each having a pair of lower ends. Base mechanisms (14) are provided for holding the lower ends of the arches (12) to position them in longitudinally spaced, transversely extending, vertical positions. A plurality of panels (22) of a flexible web material are stretched between the arches (12). Each panel has a pair of opposite side edges, a width corresponding to a longitudinal distance between adjacent ones of the arches (12) and a length corresponding to a transverse distance spanned by the arches. A first pair of lines (28, 30) is connected to a first end portion of each panel (22) and a second pair of lines is connected to an opposite second end portion of the same panel (22). The lines extend generally arcuately between the side edges of the panel (22) and are spaced a predetermined distance apart in the transverse direction. The base mechanisms (14) guide the terminal segments of each line so that they can be pulled together to thereby transversely tension the panels (22) between the arches (12). <IMAGE></p> |
