<p>A building structure employing an easily erected and dismantled frame with a stressed membrane cover wherein the framework comprises a plurality of transversely disposed arch-like members spaced longitudinally of the building with a strip of fabric stretched between each adjacent pair of arches, each of said frame members being of an extruded aluminum alloy I beam having a web with an exterior crosshead and an interior crosshead. The I beam's exterior crosshead has a fabric capturing device interacting therewith to secure the edge of the fabric strip against escape and provide a weatherproof joint between the fabric and the beam. Extendable spreader bears are mounted on the upper side of the interior crosshead, they and any appurtenances other than the fabric capturing device already mentioned connected to or slung from the arch frame beams being positioned below the fabric membrane where they are protected from the weather and readily accessible from within the structure. To facilitate the handling, transport, erection and dismantling of the structure, the arches consist of a number of disconnectable small size lightweight components and all the separate parts of the frame are connected by bolts.</p> |
