Abstract: A high temperature industrial roof assembly having two refractory bricks with adjacent faces, opposing hanger recesses, a hanger rod extending from the recesses to the top of the assembly, the refractory bricks being held in an adjacent position by a securing device, a hanger rod with a locking mechanism at one end and a hook at the other end, a hanger having opposed refractory engaging projections adapted to engage the hanger recesses, a hanger rod hole allowing free rotation about the hanger rod end above the locking mechanism, and a locking mechanism engagement recess which when engaged with the locking mechanism prevents rotation of the hanger rod in relation to the hanger at 90 degree increments and provides that depression of the one end of the hanger rod into the locking mechanism engagement recess permits rotation of the hanger rod with respect to the hanger. The locking mechanism comprises opposing tabs.

Abstract: A high temperature industrial furnace roof assembly wherein two refractory bricks are held in adjacent position by suitable securement and have a hanger rod extending from the assembly to suspend the roof assembly from a support structure in desired position in a furnace roof. The hanger rod is maintained in locked position when the weight of the roof assembly is placed upon it. The hanger rod may be depressed into the refractory bricks permitting free rotation of the hanger rod with respect to the hanger and brick assembly and locked into desired position at 90.degree. increments by a force applied to the hanger rod in a direction away from the brick assembly. The roof assembly of this invention is particularly desirable for furnace roof repair and provides for easy installation in operating high temperature furnaces permitting the long axes of the repair assembly to be changed on the jobsite by rotation of the hanger.

Abstract: A high temperature refractory structure having refractory brick lining including a support frame, a plurality of spaced hanger beams inwardly from the support frame and having opposed flanges, a plurality of spaced hanger beam clips engaging one of the hanger beam flanges for attachment to a support frame, a plurality of refractory hangers engaging the other of the hanger beam flanges, and a plurality of refractory bricks supported by the refractory hangers, the refractory hangers engaging hanger flanges of refractory bricks thereby supporting the refractory brick lining, the refractory brick hanger flanges being at approximately right angles to the hanger beam flanges. Also disclosed is a sheet metal beam clip of substantially U-shape for fastening one beam at right angles to another.
