Claim 3

A prefabricated exterior wall section in accord with claim 1 comprising insulation means disposed in the space between said panels.

Claim 4

A prefabricated exterior wall section in accord with claim 1 where the reinforcing means of the lintel comprises elongated metal rods embedded in the concrete structure thereof, each of said rods having opposite ends that respectively project laterally outwardly of said opposite end surfaces.

Claim 5

A prefabricated exterior wall section in accord with claim 1 where the one of said panels that is located at the exterior side face of the section has a brick veneer surface covering that includes spaced bricks, and mortar which is located in the spaces between said bricks and which is joined to and precast integrally with the concrete structure of said one of said panels.

Claim 6

A prefabricated exterior wall section in accord with claim 4 where said brick veneer surface covering includes bricks that project laterally outwardly of the opposite side edge surfaces of said one of said panels.

Claim 7

An exterior building wall comprising a poured-in-place concrete corner column that is supported upright on a foundation for said wall, and a pair of prefabricated wall sections that are supported upright on the foundation and define the space occupied by said corner column; each of said wall sections having an exterior side face, and an interior side face that is arranged in a vertical plane which is perpendicular to the vertical plane of the interior side face of the other wall section, and each of said wall sections comprising a pair of substantially rectangular, reinforced concrete wall panels that are spaced apart in a face to face arrangement and respectively located at the interior and exterior side faces of its wall section, an elongated horizontally arranged reinforced concrete lintel that is supported by the panels of its wall section and overlies the space therebetween, and a plurality of elongated metal elements that are spaced apart and extend through the space between said wall panels; said lintel comprising a concrete structure having an end surface which confronts the space occupied by said corner column and which lies in the plane common to the interior side face of the other wall section, and elongated horizontally arranged concrete reinforcing metal rods which are embedded in the concrete structure of the lintel and which have end portions that project outwardly from said end surface and into the space occupied by said column; each of said wall panels having an upper portion, and a side edge surface which confronts the space occupied by said column and which lies in the plane common to the interior side face of the other wall section, and each of said wall panels comprising a concrete structure which is joined along its upper portion to, and precast integrally with, the concrete strUcture of said lintel, and reinforcing means embedded in its concrete structure, each of said metal elements having opposite ends respectively embedded in the concrete structures of said wall panels and respectively secured to the reinforcing means embedded therein, and the one of said panels that is located at the exterior side face of the wall section having a brick veneer surface covering that includes spaced bricks, and mortar which is located in the spaces between said bricks and which is joined to and precast integrally with the concrete structure of said one of said panels, said bricks including bricks that project laterally outwardly of the side edge surface of said one of said panels and confront the space occupied by said column, and the space between said panels being arranged to communicate along the side edge surfaces thereof with the space occupied by said column.

Claim 8

An exterior building wall comprising a poured-in-place concrete corner column that is supported upright on a foundation for said wall, and a pair of prefabricated wall sections that are supported upright on the foundation and define the space occupied by said corner column; each of said wall sections having an exterior side face, and an interior side face that is arranged in a vertical plane which is perpendicular to the vertical plane of the interior side face of the other wall section, and each of said wall sections comprising a pair of substantially rectangular, reinforced concrete wall panels that are spaced apart in a face to face arrangement and respectively located at the interior and exterior side faces of its wall section, an elongated horizontally arranged reinforced concrete lintel that is supported by the panels of its wall section and overlies the space therebetween, and a plurality of elongated metal elements that are spaced apart and extend through the space between said wall panels; said lintel comprising a concrete structure having an end surface which confronts the space occupied by said corner column and which lies in the plane common to the interior side face of the other wall section, and elongated horizontally arranged concrete reinforcing metal rods which are embedded in the concrete structure of the lintel and which have end portions that project outwardly from said end surface and into the space occupied by said column; each of said wall panels having an upper portion, and a side edge surface which confronts the space occupied by said column and which lies in the plane common to the interior side face of the other wall section, and each of said wall panels comprising a concrete structure which is joined along its upper portion to, and precast integrally with, the concrete strUcture of said lintel, and reinforcing means embedded in its concrete structure, each of said metal elements having opposite ends respectively embedded in the concrete structures of said wall panels and respectively secured to the reinforcing means embedded therein, and the one of said panels that is located at the exterior side face of the wall section having a brick veneer surface covering that includes spaced bricks, and mortar which is located in the spaces between said bricks and which is joined to and precast integrally with the concrete structure of said one of said panels, said bricks including bricks that project laterally outwardly of the side edge surface of said one of said panels and confront the space occupied by said column, and the space between said panels being arranged to communicate along the side edge surfaces thereof with the space occupied by said column.

Claim 9

An exterior building wall in accord with claim 6 where the space between the panels of each of said wall sections is occupied by insulation means.

Claim 10

An exterior building wall in accord with claim 6 where said foundation has reinforcing rods with ends projecting vertically thereabove and into the foot end of the space occupied by said column, where said column has elongated reinforcing metal rods connected to the rod ends that project into the foot end of said space and to the end portions of the metal rods of said lintel.
