Insulated building structure and method for assembling same

Claim 2

A wall insulation unit comprising: a pair of laterally spaced, identical, elongated, blocks of plastic cellular foam insulation material, one block in mirror relationship to the other but spaced apart therefrom by at least the thickness of a block; each block having one side face with a central, vertical recess of predetermined width and depth and a pair of vertical recesses, each at an opposite end thereof and equal in depth to said predetermined depth and equal in width to one half the predetermined width of said central recess for receiving the major portion of the depth of vertical wall studs with the minor portions thereof protruding from said recesses and each block having a top face a bottom face and two opposite end faces, each with a tongue and groove configuration thereon adapted to mate and interengage with corresponding tongue and groove configurations of juxtaposed blocks to seal the joints therebetween;

Claim 3

A wall insulation unit as specified in claim 1 wherein: the top face of each block has two longitudinally extending tongues separated by three longitudinally extending tongue grooves; and the bottom face of each block has three longitudinally extending tongues and two longitudinally extending tongue grooves.

Claim 4

A wall insulation unit as specified in claim 1 wherein: each said block has its other side face with a plurality of parallel, spaced apart, vertical shallow grooves therein.

Claim 5

A wall insulation unit as specified in claim 2 wherein: said longitudinally extending tongues and grooves on said top face and on said bottom face have the longitudinally extending edges and corners thereof curved to prevent inadvertent breakage of the foam material thereof.

Claim 6

A wall insulation unit as specified in claim 1 wherein: each said block has its other side face with a gridlike pattern of spaced apart horizontal shallow grooves intersecting spaced apart vertical shallow grooves.

Claim 7

A wall insulation unit as specified in claim 1 wherein: each said block includes upper central and opposite end cut-outs and lower central and opposite end cut-outs for receiving tie rod-spacer elements.

Claim 8

A building side wall comprising: an outer set of vertical studs, spaced a predetermined distance apart; and extending along the periphery of the building; an inner set of vertical studs extending along the periphery of said building, in parallelism with the studs of said outer set, at a spaced distance therewithin, to form a double row of spaced apart studs; the studs of the inner set being each opposite a stud of the outer set; a plurality of wall insulation units, each unit comprising a pair of laterally spaced, identical, elongated, blocks of plastic cellular foam insulation material; each block of each pair having an elongated, stud contacting side face with a plurality of vertical stud receiving recesses, equal in depth to the major portion of the depth of a stud, so that a minor portion of a stud will project therefrom; each block having a top face, a bottom face and two opposite end faces, each with a tongue and groove configuration for interengaging with the corresponding tongue and groove configuration of juxtaposed blocks for sealing the joints therebetween, one set of said pairs of blocks being assembled into an insulative outer wall in the spaces between said outer set of studs and the other set of blocks of the pairs being assembled into an insulative inner wall in the spaces between said inner set of vertical studs; the resulting inner and outer insulated block walls being spaced apart at least a distance equal to the thickness of a block to provide an air insulation gap therebetween and to permit sliding of blocks along said space during said assembly.

Claim 9

A building side wall comprising: an outer set of vertical studs, spaced a predetermined distance apart; and extending along the periphery of the building; an inner set of vertical studs extending along the periphery of said building, in parallelism with the studs of said outer set, at a spaced distance therewithin, to form a double row of spaced apart studs; the studs of the inner set being each opposite a stud of the outer set; a plurality of wall insulation units, each unit comprising a pair of laterally spaced, identical, elongated, blocks of plastic cellular foam insulation material; each block of each pair having an elongated, stud contacting side face with a plurality of vertical stud receiving recesses, equal in depth to the major portion of the depth of a stud, so that a minor portion of a stud will project therefrom; each block having a top face, a bottom face and two opposite end faces, each with a tongue and groove configuration for interengaging with the corresponding tongue and groove configuration of juxtaposed blocks for sealing the joints therebetween, one set of said pairs of blocks being assembled into an insulative outer wall in the spaces between said outer set of studs and the other set of blocks of the pairs being assembled into an insulative inner wall in the spaces between said inner set of vertical studs; the resulting inner and outer insulated block walls being spaced apart at least a distance equal to the thickness of a block to provide an air insulation gap therebetween and to permit sliding of blocks along said space during said assembly.

Claim 10

A combination as specified in claim 7 wherein: said building side wall includes applurality of tie rod-spacer elements each extending between a stud of the inner set and an opposite stud of the outer set at each course of said blocks and each said block includes upper and lower, central and opposite end cut outs for receiving said tie rod-spacer elements.

Claim 11

A combination as specified in claim 7 wherein: said side wall includes a plurality of filler blocks, of said plastic foam material, adapted to fill the spaces between the protruding minor portions of said studs to form a smooth outer, or inner, wall surface for receiving outside stucco or inside plaster.

Claim 12

A combination as specified in claim 7 wherein: said building side wall includes a plurality of longitudinally extending strips of said plastic foam material, equal in width to the width of the space between the blocks in the inner set of studs and the blocks in the outer row of studs, each said strip lying on the tie rod-spacers between said sets of studs of one of the horizontal joints between vertical courses to serve as a back up when plaster or stucco is applied to said blocks.

Claim 13

A combination as specified in Claim 8 wherein: said tie rod spacer elements are formed of metal mesh channel with a belt therethrough from the building footing to about ground level and are formed of wood with a bolt therethrough above ground level.

Claim 14

A combination as specified in claim 7 wherein: said studs are of 2"×3" wood material; said blocks are of polystyrene plastic cellular foam material; each block is twenty eight inches high, forty eight inches long and three inches thick and the space between the inner set of studs and the outer set of studs is about four inches in width.
