Abstract

Abstract Building panels adapted to form the exterior enclosure of a prefabricated home are disclosed. The building panels are a sandwich composed of masonry elements such as bricks, synthetic polyester mortar, reinforcing wire mesh, a polymer foam, and a suitable inner facing layer, all held together by the mortar and foam. The method includes placing bricks in the desired arrangement of a support layer, joining the bricks by applying polyester mortar to the back side of the bricks and between adjacent bricks, applying the reinforcing wire mesh within the mortar, spacing the outer facing layer from the wire mesh, and then introducing a foam polymer which is cured in the space between the wire mesh polyester and the outer facing layer.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 136 words
A PREFABRICATED BUILDING PANEL ADAPTED TO BE COUPLED WITH AN ADJACENT BUILDING PANEL TO FORM THE WALL OF A BUILDING, SAID PANEL HAVING AN OUTER WEATHERING OR FACING LAYER TO DEFINE THE OUTER SURFACE OF A BUILDING, SAID PANEL HAVING AN INNER FACING LAYER TO DEFINE THE WALLS OF A ROOM IN A BUILDING, SAID OUTER FACING LAYER BEING DEFINED BY A PLURALITY OF MASONRY MEMBERS BONDED TOGETHER BY A LAYER OF POLYSTYRENE MORTAR, SAID MORTAR EXTENDING ACROSS THE BACK OF SAID MASONARY MEMBERS AND IN THE SPACE BETWEEN ADJACENT MEMBERS, A LAYER OF CLOSED CELL FOAM URETHANE POLYMER BETWEEN THE LAYER OF MORTAR AND THE INNER FACING LAYER, SAID FOAM POLYMER BONDING SAID INNER FACING LAYER TO SAID LAYER OF MORTAR, AND A REINFORCEMENT WIRE MESH BETWEEN SAID FOAM POLYMER AND LAYER OF POLYESTER MORTAR.
Claim 2
Dependent Claim 136 words
A PREFABRICATED BUILDING PANEL ADAPTED TO BE COUPLED WITH AN ADJACENT BUILDING PANEL TO FORM THE WALL OF A BUILDING, SAID PANEL HAVING AN OUTER WEATHERING OR FACING LAYER TO DEFINE THE OUTER SURFACE OF A BUILDING, SAID PANEL HAVING AN INNER FACING LAYER TO DEFINE THE WALLS OF A ROOM IN A BUILDING, SAID OUTER FACING LAYER BEING DEFINED BY A PLURALITY OF MASONRY MEMBERS BONDED TOGETHER BY A LAYER OF POLYSTYRENE MORTAR, SAID MORTAR EXTENDING ACROSS THE BACK OF SAID MASONARY MEMBERS AND IN THE SPACE BETWEEN ADJACENT MEMBERS, A LAYER OF CLOSED CELL FOAM URETHANE POLYMER BETWEEN THE LAYER OF MORTAR AND THE INNER FACING LAYER, SAID FOAM POLYMER BONDING SAID INNER FACING LAYER TO SAID LAYER OF MORTAR, AND A REINFORCEMENT WIRE MESH BETWEEN SAID FOAM POLYMER AND LAYER OF POLYESTER MORTAR.
Claim 3
Dependent Claim 60 words
A building panel in accordance with claim 1 wherein said panel is longer than its width, said masonry members being rectangular bricks which are thinner than their height, the long sides of the bricks being perpendicular to the long sides of the panel, and the foam polymer having a slot for receiving a spline for joining two adjacent panels together.
Claim 4
Dependent Claim 45 words
A panel in accordance with claim 1 including a downwardly facing top channel and an upwardly facing bottom channel, a plurality of said panels being disposed within said channels, and field applied masonry members applied in alternate rows interconnecting the side edges of adjacent panels.
Claim 5
Dependent Claim 173 words
A prefabricated building panel adapted to be coupled with an adjacent building panel to form the wall of a building, said panel having an outer weathering facing layer to define the outer surface of a building, said panel having an inner facing layer to define the walls of a room in a building and of a material different from said outer facing layer, said outer facing layer being thicker than the inner facing layer and defined by a plurality of masonry members bonded together by a layer of polyester mortar, said mortar extending across the back of said masonry members and in the space between adjacent members, said panel being longer than its width, said masonry members being rectangular bricks which are thinner than their height, the long sides of the bricks being perpendicular to the long sides of the panel, and a layer of closed cell foam urethane polymer between the layer of mortar and the inner facing layer, said foam polymer bonding said inner facing layer to said layer of mortar.
Claim 6
Dependent Claim 173 words
A prefabricated building panel adapted to be coupled with an adjacent building panel to form the wall of a building, said panel having an outer weathering facing layer to define the outer surface of a building, said panel having an inner facing layer to define the walls of a room in a building and of a material different from said outer facing layer, said outer facing layer being thicker than the inner facing layer and defined by a plurality of masonry members bonded together by a layer of polyester mortar, said mortar extending across the back of said masonry members and in the space between adjacent members, said panel being longer than its width, said masonry members being rectangular bricks which are thinner than their height, the long sides of the bricks being perpendicular to the long sides of the panel, and a layer of closed cell foam urethane polymer between the layer of mortar and the inner facing layer, said foam polymer bonding said inner facing layer to said layer of mortar.
Claim 7
Dependent Claim 22 words
A building panel in accordance with claim 4 including a reinforcement wire mesh between said foam polymer and layer of polyester mortar.
Claim 8
Dependent Claim 35 words
A prefabricated building panel in accordance with claim 4 wherein said outer facing layer is thicker than said inner facing layer, said polymer and mortar being thicker than the combined thickness of the facing layers.
