ABSTRACT:
A stirrup apparatus for cooperation with an associated buckstay that has at least one flange and which extends around an associated furnace. The stirrup apparatus includes a wall channel extending generally horizontally around the associated furnace. The apparatus also includes an elongated bent plate having first and second ends, the plate being elongated intermediate the first and second ends. The first and second ends are welded to the wall channel at spaced parts of the wall channel with an axial part of the plate intermediate the first and second ends spaced from the wall channel. At least a first elongated bar is welded on a side of the bent plate that faces the wall channel and extends generally in a direction that is perpendicular to the direction of elongation of the bent plate. The apparatus also includes first and second generally L-shaped retainers, each of the L-shaped retainers is dimensioned and configured to extend from the first elongated bar around an associated flange of the associated buckstay. The first and second L-shaped retainers are welded to the first elongated bar at axially spaced parts thereof. Some forms of the apparatus further includes a second elongated bar welded on a side of the bent plate that faces the wall channel amd extends generally in a direction that is perpendicular to the direction of elongation of the bent plate. Some embodiments have first and second generally L-shaped retainers that are each dimensioned and configured to extend from the second elongated bar around a flange of the associated buckstay, the first and second L-shaped retainers are welded to the first and second elongated bars at axially spaced parts thereof.
