Claim:
An assembly for facilitating the attachment of a metal hood to a concrete shell and compensating for relative radial thermal expansion of the hood and the shell, comprising: a shoulder plate affixed to the bottom of the hood; an elastomeric bearing pad located between the shoulder plate and the shell; a plurality of anchor rods having a top end extending upwardly from the concrete shell and a bottom end extending through the shoulder plate and partially embedded in the concrete shell; a corresponding plurality of rod-engaging bores perforating the shoulder plate, each of the bores having a cross sectional area greater than the cross sectional area of the rod engaged therewith; a pipe sleeve of circular cross section fitted around each anchor rod and extending through the bores of the shoulder plate; a plurality of gusset plate pairs mounted on the top of the shoulder plate, wherein each anchor rod is straddled by a pair of gusset plates; and a perforated cap mounted directly on top, and thus in contact with the pair of gusset plates, wherein the anchor rod passes though the perforated cap and a nut threadably engaged to the anchor rod above the perforated cap secures the metal hood to the concrete shell.
