A dome building structure employs an inflatable form having a peripheral edge secured to a base. A network of cable-like members overlies the form and is secured to the base so as to restrain pressurized inflation of the form to prevent tearing. A layer of insulating foam is applied to the inner surface of the inflated form followed by attachment of a reinforcing mesh and application of a cementitious layer sufficient to embed the mesh. Internal ribs are formed to directly underlie the network of external cable members which may be interconnected to the internal ribs to assist in support of the ribs until they become self-supporting of the dome. The external network of cable-like members allows the form to extend convexly outwardly or pooch through interstices in the cable network creating smaller radii of curvature to better withstand inward buckling.

[ I claim:] [1.] A method of constructing a dome building comprising the steps of securing a peripheral edge of an inflatable form to a base, securing a network of external flexible cable restraining members to the base so that the restraining members overlie said form, inflating said form under pressure into a dome shape so that outward expansion of the form is restricted by said restraining members being placed in longitudinal tension, forming a layer of insulation foam material on an inner surface of the inflated form, securing a reinforcing mesh to an inner surface of said foam layer, applying one or more layers of a cementitious material to the inner surface of said foam layer to a depth sufficient to embed said reinforcing mesh, forming a network of reinforcing bars internally of said foam layer so that said reinforcing bars generally underlie said external network of restraining members, applying one or more layers of cementitious material to said network of reinforcing bars to a depth sufficient to embed said reinforcing bars so that cementitious ribs are formed by said embedded reinforcing bars to underlie said external network of restraining members, and relieving pressure from internally of said form after said cementitious material has set so that a self-supporting dome is formed independently of said restraining members.
