Abstract
A foam-cement building having the walls, roof and/or floor formed from a plurality of self supporting foam building blocks of varying density with a strong thin continuous structural and architectural coating on the surface of the blocks, the coating being formed from cement, reinforced with a fiberglass mesh and fiberglass roving strands, the blocks being interconnected by a mechanical key system or splines to form a monolithic structure.
Claims26
A building formed from a number of load-bearing preformed insulating blocks, said building comprising a floor formed by a number of preformed insulating blocks joined at the edges to form a continuous floor,
- a number of walls supported on said floor, each of said walls being formed from a number of preformed insulating blocks joined at the edges to form a continous wall and a roof formed by a number of performed insulating blocks joined at the edges to form a continuous roof structure and being supported on said walls,
- said insulating blocks being formed from a molded foam and a fiber reinforced cement coating covering the entire exterior surface of said roof, said walls and said floor, and adhesive
- means joining said edges of the blocks to form said walls, roof and floor.
A composite load-bearing building block adapted be joined in edge to edge relation with a corresponding block to form a wall, roof or floor, said block comprising a foam core having a sufficient width to form a load-bearing structure and
- a coating on at least one surface of said core, said coating being formed from a composition including Portland cement, sand, cut fiberglass roving strands and a polymer adhesive, said composition being applied to a reinforcement grid located on the outer surface of said core, whereby said grid is embedded in said cementitious coating.
A load-bearing thermally insulating fire-resistant building wall formed from preformed blocks joined at their edges to form a continuous wall, each block comprising
- a foam core having a thickness of 6 to 24 inches and
- a coating on the inside and outside surfaces of said core, said coatings including a fiberglass reinforced fabric on the surfaces of said core and a cementitious material, including cut fiberglass roving strands, applied to the external surface of said fabric to a thickness of approximately 1/4 to 1/2 inch to secure said fabric to said core whereby said blocks have integrally related, load-bearing, tensile and fire-resistant characteristics.
A load-bearing building block comprising a foam core having a length up to sixteen feet and a height up to four feet and a cementitious coating on at least one surface, said coating including a reinforcement grid and cement composition having fiberglass roving strands mixed therein, said composition penetrating said grid and bonding said coating to said core, said core having a width which, when combined with the reinforced coating forms a load-bearing structure.
A building having external walls formed from a plurality of preformed load-bearing cement foam core blocks of a predetermined configuration adapted to be joined at their edges at the building site to form a rigid wall, each block comprising
- a foam core up to sixteen feet in length and four feet in height and of a sufficient width to be self-supporting,
- means on each edge of said core for matingly engaging the adjacent blocks and
- a cementitious coating on the exterior surface of said foam core to enhance the load-bearing capabilities of said wall, said coating including a reinforcing grid located on the surface of said core and a composition covering said grid, said composition including
- predetermined amounts of cement, sand, cut fiberglass rovings and a polymer adhesive, said grid being embedded in said composition and bonded to said core whereby said block has sufficient load-bearing strength to form the building walls.
