Abstract

Abstract An anchor tile hanger for anchoring refractory brick to the roof of a furnace structure is comprised of a pair of vertically spaced apart plates having aligned cutouts in the upper edges which cutouts are adapted to engage the lower horizontal portion of a suspended I-beam. Attached to each of the ends of the vertically aligned plates are a pair of U-shaped rods each having a bight portion turned inwardly and facing one other which are adapted to engage and anchor the refractory tile or brick. The cutouts in the vertical disposed plates include overhang portions for positioning the tile hanger about the lower horizontal portions of the I-beam and clearance areas which facilitate assembly and insection of the tile hanger about the lower horizontal portion of the I-beam.
