ABSTRACT:
A refractory brickwork wall having an opening therethrough has incorporated therein, at a position above the opening, a relief brickwork configuration in the form of a gable or roof. The relief brickwork includes a plurality of relief bricks each having an upper inclined surface, a lower inclined surface and a lower, generally horizontal step surface. The relief bricks are arranged one above the other in an inclined formation with the lower inclined surface of the upper relief brick of each pair of adjacent relief bricks resting on the upper inclined surface of the lower relief brick of such pair of adjacent relief bricks, and with the upper relief brick of each pair of adjacent relief bricks being partially offset in a horizontal direction from the lower relief brick of such pair of adjacent relief bricks. The horizontal step surface of the upper relief brick of each adjacent pair of relief bricks extends horizontally at least partially beyond the lower relief brick of such pair of relief bricks and faces a surface of one of the refractory bricks of the wall and defines therewith a joint. All such joints are filled with a compressible fireproof material.
