Abstract
Disclosed is an inflatable value having a multilobed double wall, adapted to be opened out and retracted, and confining a layer of intermural air under pressure. The vault is constructed by assembling side by side a plurality of separate inflatable hollow beams, each of which includes at least two longitudinal panels which are sequentially connected together along at least two longitudinal edges. The panels of each beam are connected together and to panels of adjoining beams by a plurality of short quick-connect type female connectors. The joints between panels of each respective beam are made leaktight by including flexible membranes which span the respective joints. The inflatable vault according to the invention is particularly applicable to the covering of stadiums, swimming pools, tennis courts, restaurants, auditoriums, storage hangers and other large installations.
