Abstract
Abstract A WALL STRUCTURE HAVING A PAIR OF SPACED WALLS FOR RECEIVING A STRUCTURAL MATERIAL SUCH AS CONCRETE THEREBETWEEN HAS SPACER MEMBERS EXTENDING BETWEEN THE WALLS TO MAINTAIN THE REQUIRED SEPARATION. THE STRUCTURE IS DESIGNED SO THAT EACH SPACER MAY BE SECURED TO ONE WALL AT ANY OF A PLURALITY OF POSITIONS ALONG A FIRST LINE AND, TO THE SECOND WALL, AT ANY OF A PLURALITY OF POSITIONS ALONG A SECOND LINE ANGULARLY DISPOSED TO THE FIRST LINE. IN ERECTING SUCH A STRUCTURE, EACH SPACER CAN BE DISPOSED AT THE POSITION WHERE THE FIRST AND SECOND LINES EFFECTIVELY INTERSECT WITHOUT REQUIRING PRECISE ALIGNMENT OF THE TWO WALLS.
