Abstract
A method and means by which buildings, particularly residential buildings, can be prefabricated of cut-to-size metal wall framing and roof member elements for erection upon a prepared foundation at the site, the building framework thus erected being adapted to structural completion by a process involving scratch cement-plaster coating the outsides of expanded sheet metal enclosing the rib-work of the walls and the underside of roofing rib framework assembly, and thereafter pump-spraying a cementacious mixture between the voids of such rib-work against the opposite side of the scratch-coated expanded sheet metal to provide a substantially monolithic steel-reinforced basic building structure.

A monolithic steel reinforced cementacious material building structure, comprising, in combination, a plurality of outer wall panels, each wall panel comprising a plurality of formed sheet metal ribs of U-shaped cross-section arranged in spaced, parallel relation and defining a predetermined interior wall thickness, a covering of uniformly apertured sheet metal secured directly against one side of each of the ribs of said wall panels, a coating of cementacious material on the outside of said apertured sheet metal covering, a monolithic filling of cementacious material between the ribs of each of said wall panels and extending through to the other side of each of said ribs, said panels being secured in end-to-end abutting relation to define the outer periphery of a building, a plurality of formed metal steel beams spanning and secured to upper end portions of opposite side walls of said building outer periphery and arranged in spaced, parallel relation thereupon, a plurality of spaced, parallel formed sheet metal roofing rib members fixed upon and secured to said roof beams in perpendicularly crossing relation with respect thereto, a covering of uniformly apertured sheet metal secured against the underside of said roofing ribs, a coating of cementacious material on the underside of said apertured sheet metal covering said roofing ribs, a filling of cementacious material between said roofing ribs above said roofing rib apertured sheet metal covering and providing a roof deck, and an outer layer of roof sealant applied to the outside of said roof deck.
