Building wall unit

Claim 2

A RECTANGULAR WALL UNIT FOR BUILDING CONSTRUCTION HAVING TWO OPPOSITE FACE SIDES AND FOUR INTERCONNECTING EDGE SIDES COMPRISING: A COMPOSITION COMPRISING: A CURED MINERAL BONDING MATERIAL OF HYDRATED LIME AND SILICA FLOUR AND WHEREIN: THE RATIO, BY VOLUME, OF HYDRATED LIME TO THE SUM OF HYDRATED LIME AND SILICA FLOUR OF SAID BONDING MATERIAL IS .4 TO .6, AND WHERE THE RATIO, BY VOLUME, OF CONSTITUENTS IS WITHIN THE RANGE OF ONE PART BONDING MMATERIAL TO ONE TO FOUR PARTS AGGREGATE AND APPLIED WATER 7 TO 12 PERCENT, A LIGHTWEIGHT AGGREGATE HAVING A DENSITY OF .08 TO .6 AND COMPRISING AT LAST ONE OF THE FOLLOWING: STYROFOAM, PUMICE, PERLITE, VERMICULITE, GLASS NODULES, OR PUFFED-UP CERAMIC, SAID EDGE SIDES OF SAID UNIT ARE OF TONGUE AND GROOVE CONFIGURATION, WITH ONE OF EACH TWO PARALLEL EDGE SIDES HAVING AT LEAST A TONGUE-SHAPED PROTRUSION AND THE OTHER HAVING A COMPLEMENTARY GROOVE, AND AT LEAST ONE CAVITY EXTENDING BETWEEN A PAIR OF OPPOSITE EDGE SIDES OF SAID UNIT.

Claim 3

A wall unit as set forth in claim 1 wherein said silica flour is fine ground with a residue of 5 percent to 30 percent through a No. 200 type screen and with 5 percent to 0 percent residue through a No. 140 size screen.

Claim 4

A wall unit as set forth in claim 2 wherein the ingredients are placed in a mold, forming the wall unit, and then cured in high pressure steam of from 300 to 350 PSI for 2 to 8 hours.

Claim 5

A rectangular wall unit for building construction having two opposite face sides and four interconnecting edge sides and wherein: two said edges comprise three tongue-shaped protrusions, a central protrusion having tapered sides and two lower protrusions each having tapered sides and one being positioned on either side of said central protrusion; two said edges comprise three grooves complementary to the size and shape of said three tongue-shaped protrusions except that the groove corresponding to the position of said central protrusion is of greater depth than the height of a said central protrusion, whereby a spacing between wall units is provided when wall units are joined for the application of a bonding agent or reinforcement member; a composition of cured mineral bonding material and a lightweight aggregate having a density of .08 to .6; and at least one cavity extending between a pair of opposite edge sides of said unit.

Claim 6

A rectangular wall unit for building construction having two opposite face sides and four interconnecting edge sides and wherein: two said edges comprise three tongue-shaped protrusions, a central protrusion having tapered sides and two lower protrusions each having tapered sides and one being positioned on either side of said central protrusion; two said edges comprise three grooves complementary to the size and shape of said three tongue-shaped protrusions except that the groove corresponding to the position of said central protrusion is of greater depth than the height of a said central protrusion, whereby a spacing between wall units is provided when wall units are joined for the application of a bonding agent or reinforcement member; a composition of cured mineral bonding material and a lightweight aggregate having a density of .08 to .6; and at least one cavity extending between a pair of opposite edge sides of said unit.

Claim 7

A building having a plurality of side walls and ceiling member extending between said side walls and wherein at least one of said side walls comprises a plurality of rectangular wall units, each wall unit having two opposite face sides and four edge sides in turn comprising: a composition comprising a mineral bonding material from the group of cement and lime and a lightweight aggregate having a density of .08 to .6; said edge sides of each said wall unit being of tongue and groove construction with one of each two opposite edge sides having at least a tongue-shaped protrusion and the other having a complementary groove; at least one cavity extending between a pair of opposite side edge sides of a said wall unit; said wall unit being joined in a tongue and groove relationship; a plurality of ceiling adapter units, each having a lower side corresponding to an edge side of a said wall unit and an upper plane surface; and a structural slab ceiling resting on said plane surface of said adapter units between walls of said building.

Claim 8

A building having a plurality of side walls and ceiling member extending between said side walls and wherein at least one of said side walls comprises a plurality of rectangular wall units, each wall unit having two opposite face sides and four edge sides in turn comprising: a composition comprising a mineral bonding material from the group of cement and lime and a lightweight aggregate having a density of .08 to .6; said edge sides of each said wall unit being of tongue and groove construction with one of each two opposite edge sides having at least a tongue-shaped protrusion and the other having a complementary groove; at least one cavity extending between a pair of opposite side edge sides of a said wall unit; said wall unit being joined in a tongue and groove relationship; a plurality of ceiling adapter units, each having a lower side corresponding to an edge side of a said wall unit and an upper plane surface; and a structural slab ceiling resting on said plane surface of said adapter units between walls of said building.

Claim 9

A building as set forth in claim 5 wherein said adapter units are basically of L-shaped construction, having a vertical plate portion adapted to cover ends of a said slab, thereby providing a continuous outer appearance of a building with the ends of said slab thus hidden.

Claim 10

A building as set forth in claim 5 wherein said cavities of said wall units are aligned vertically and further comprising: reinforcing material extending vertically through at least one elongated cavity formed by a plurality of aligned said cavities.

Claim 11

A building as set forth in claim 7 wherein an insulating material is contained within a plurality of said cavities.

Claim 12

A building as set forth in claim 5 wherein there is included an interior wall between two other said walls, a said ceiling adapter supporting abutting ends of ceiling slabs on said interior wall, said abutting ends of said ceiling slabs being spaced, and a course of bonding material extending between said spaced ends of said slabs to said ceiling adapter.

Claim 13

A building as set forth in claim 5 comprising: a slot extending horizontally through a plurality of side-by-side said wall units; and a steel reinforcement member extending horizontally through said slot.
