Abstract
A refractory brick wall system for towers and the like which includes an outside casing and a plurality of bricks laid up in a pattern on the inside of the casing. Tie-back devices secure the bricks to the casing and allow for relative horizontal and relative vertical movement between the bricks and the casing. A plurality of shelves are fixed to the inside of the casing at vertically spaced intervals to provide support for the bricks in vertical sections thereof. A lightweight, insulating refractory material is cast between the casing and the bricks. The bricks themselves are shaped with ring and groove sides for interlocking of the bricks in a laid-up wall construction thereof.
Claims15
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.
