Claim 7

A plurality of building blocks stacked vertically to form a continuous vertical wall, each block having a generally rectangular, thick foamed plastic body, a pair of vertically arranged, parallel preformed think rigid sheets having opposed interfaces enclosing said body and exposed outer faces, and a plurality of elongated, narrow relatively rigid furring strips disposed horizontally and secured between said body and said sheets, including a furring strip located at each of the four corners of said rectangular body having an outer vertical face secured to said interface of one of said sheets and an exposed horizontal face generally parallel to the vertical edge of said one of said sheets, the remaining faces of said strips embedded within and bonded to said plastic body, and said blocks stacked vertically with said exposed horizontal faces of said furring strips in face-to-face and load bearing contact and said sheet outer faces forming a continuous vertical surface.

Claim 8

The vertical wall defined in claim 5, wherein the plastic body of each of said blocks includes a vertically projecting portion extending beyond said horizontal exposed faces of said furring strips at one horizontal end and a conforming channel at the opposed horizontal end, and said blocks stacked with one projecting body portion received within the channel of the next vertical block in interlocking relation.

Claim 9

A wall forming block comprising: a pair of vertically arranged, parallel, spaced apart, pre-formed, thin rigid sheets each having exposed outer faces and facing inner faces; an elongated, narrow, rigid furring strip horizontally disposed and secured in face to face contact to one of said sheet inner faces at a distance between the upper and lower edges of the sheet and extending along the length of the sheet; a thick foamed plastic material block body arranged between the sheets and bonded to their inner faces, and with the furring strips completely embedded within and bonded to the plastic material, except for the strip portion which is in face to face contact with its sheet; the block being formed for edge to edge alignment with and stacking with other such blocks into courses to form a wall; whereby face covering panels and wall attachments may be applied upon the wall and said furring strip transfers and spreads loads to and from the rigid sheet to which it is fastened and also the plastic block body within which it is embedded; horizontally arranged corner furring strips, each fastened to and in face to face contact with and extending along the length of the inner surface of one of said sheets at the upper and lower edges respectively of such sheet so that these corner furring strips are arranged at and form the upper and lower horizontal corners of the plastic block body, with the upper corner furring strips having an exposed upper edge surface extending along its length and the lower corner furring strip having an exposed lower edge surface extending along its lower edge, and the strip edges adjacent the plastic body being bonded to the plastic material thereof; wherein the lower corner furring strip of one block rests directly upon the upper corner furring strip of the block next below it for providiNg load bearing engagements between the blocks in adjacent courses; and wherein one of said corner furring strips is extended outwardly in the vertical plane relative to the adjacent horizontal plastic body edge to form a horizontal tongue portion, covered by its adjacent sheet edge, extending the horizontal length of the block and the other of said corner furring strips is arranged a short distance inwardly, in the vertical plane, of its adjacent horizontal plastic block edge to form an upwardly and outwardly opening groove for receiving and engaging along its length with the horizontal tongue portion formed by a block in the next adjacent course.

Claim 10

A wall forming block comprising: a pair of vertically arranged, parallel, spaced apart, pre-formed, thin rigid sheets each having exposed outer faces and facing inner faces; an elongated, narrow, rigid furring strip horizontally disposed and secured in face to face contact to one of said sheet inner faces at a distance between the upper and lower edges of the sheet and extending along the length of the sheet; a thick foamed plastic material block body arranged between the sheets and bonded to their inner faces, and with the furring strips completely embedded within and bonded to the plastic material, except for the strip portion which is in face to face contact with its sheet; the block being formed for edge to edge alignment with and stacking with other such blocks into courses to form a wall; whereby face covering panels and wall attachments may be applied upon the wall and said furring strip transfers and spreads loads to and from the rigid sheet to which it is fastened and also the plastic block body within which it is embedded; horizontally arranged corner furring strips, each fastened to and in face to face contact with and extending along the length of the inner surface of one of said sheets at the upper and lower edges respectively of such sheet so that these corner furring strips are arranged at and form the upper and lower horizontal corners of the plastic block body, with the upper corner furring strips having an exposed upper edge surface extending along its length and the lower corner furring strip having an exposed lower edge surface extending along its lower edge, and the strip edges adjacent the plastic body being bonded to the plastic material thereof; wherein the lower corner furring strip of one block rests directly upon the upper corner furring strip of the block next below it for providiNg load bearing engagements between the blocks in adjacent courses; and wherein one of said corner furring strips is extended outwardly in the vertical plane relative to the adjacent horizontal plastic body edge to form a horizontal tongue portion, covered by its adjacent sheet edge, extending the horizontal length of the block and the other of said corner furring strips is arranged a short distance inwardly, in the vertical plane, of its adjacent horizontal plastic block edge to form an upwardly and outwardly opening groove for receiving and engaging along its length with the horizontal tongue portion formed by a block in the next adjacent course.
