Refractory brick wall system

Claim 1

A refractory brick wall comprising: an outside casing; a plurality of bricks laid up in a pattern on the casing, at least some of the bricks having preformed recesses, a plurality of said bricks having inner and outer faces, spaced side faces, and top and bottom faces; and tie-back means for securing the bricks to the casing with the outer brick faces facing the casing and allowing relative horizontal and vertical movement between the bricks and the casing, there being a leg on each tie-back means loosely received in said recesses, a plurality of said bricks having means for interlocking each said brick with a plurality of adjacent bricks to prevent the interlocked bricks from moving relative to each other away from the casing, said interlocking means comprising cooperating rings and recesses on each of the side, inner and outer faces of certain of said bricks and each of the bricks immediately above, below, and on the sides of the certain of said bricks, the upper surfaces of a plurality of said bricks being angled downwardly toward the inner face to cooperate with the bottom face of overlying bricks having bottom surfaces similarly angled downwardly from the outer faces toward the inner faces thereof, said upper surfaces that are angled downwardly minimizing condensation and gas penetration between adjacent bricks.
