Claim 8

A corner block as defined in claim 6, wherein the displacement between inner and outer faces of said corner block is variable.

Claim 9

A corner block as defined in claim 7, wherein said second web is vertically apertured.

A corner block as defined in claim 8, wherein the longitudinal portion of said corner block extending between said inner and outer faces is vertically apertured such that vertical apertures of one corner block will be in air communication with corresponding apertures of another block interlocked above or below said one corner block.

Claim 11

A jamb block for use with the system of claim 5, said jamb block comprising a structural block as defined in claim 1 having one longitudinal half thereof replaced by a rectangular butt for extending the displacement between the inner and outer faces of said butt to equal the displacement between the outer faces of a pair of opposed, longitudinally and transversely interlocked structural blocks of the type defined in claim 1.

Claim 12

A jamb block as defined in claim 10, wherein the displacement between inner and outer faces of said jamb block is variable.

Claim 13

A jamb block as defined in claim 11, wherein said butt is vertically apertured.

Claim 14

A beam block for use with the system of claim 5, said beam block comprising a structural block as defined in claim 1 in which said web is truncated to extend from the bottom of said member only about one quarter to about one half the distance to the top of said member.

Claim 15

A beam block as defined in claim 13, wherein the displacement between inner and outer faces of said beam block is variable.

Claim 16

A beam block as defined in claim 14, wherein said web is vertically apertured.

Claim 17

A beam block as defined in claim 15, wherein the longitudinal portion of said beam block extending between said inner and outer faces is vertically apertured such that vertical apertures of one beam block will be in air communication with corresponding apertures of another block interlocked above or below said one block.

Claim 18

A pilaster block for use with the system of claim 5, said pilaster block comprising a structural block as defined in claim 1 in which the displacement between said inner and outer faces is greater than the corresponding displacement of said claim 1 structural block.

Claim 19

A pilaster block as defined in claim 17, wherein the displacement between inner and outer faces of said pilaster block is variable and is greater than the corresponding displacement of structural blocks as defined in claim 1.

Claim 20

A pilaster block as defined in claim 18, wherein said pilaster block is vertically apertured between inner and outer faces of said pilaster block.

Claim 21

A junction block for use with the system of claim 5, said junction block comprising a structural block as defined in claim 1, having a right angled corner between said inner and outer faces and having first and second tongue and groove bearing web portions projecting, respectively, away from first and second right angled inner faces of said junction block.

Claim 22

A junction block as defined in claim 20, wherein the displacement between said inner and outer faces is variable.

Claim 23

A junction block as defined in claim 21, wherein said first and second web portions are vertically apertured.

Claim 24

A junction block as defined in claim 22, wherein the right angled portion of said junction block extending between said inner and outer faces is vertically apertured such that vertical apertures of one junction block will be in air communication with corresponding apertures of another block interlocked above or below said one block.

Claim 25

A web block for use with the system of claim 5, said web block comprising a structural block as defined in claim 1, wherein said longitudinally extending member is truncated to extend only the width of said web such that when said web block is longitudinally and transversely interlocked with structural blocks as defined in claim 1, the outer face of said web block lies in the same plane as the innermost faces of webs of said structural blocks as defined in claim 1.
