The apparatus comprises a corrugated member adapted to be adhered to the panel to form a back face of the panel when so adhered, anchor integral with the corrugated member and extending longitudinally from an upper portion of the corrugated member and lock integral with the corrugated member and extending longitudinally from a bottom portion of the corrugated member. The lock engageable with the anchor of an adjacent panel has the corrugated member as a back face.

Abstract: A new and useful anchor for use in the installation of a composite building panel. The anchor comprises a vertically upstanding wall mounting face and a spacer extending normal to the wall mounting face. Spaced outwardly from the wall mounting face by the spacer there is provided a first longitudinally extending flange-receiving groove opening in a first vertical direction. Adjacently deposed to the first flange-receiving groove with a common middle wall there is provided a second longitudinally extending flange-receiving groove opening in an opposite vertical direction. Fasteners mount the anchor means to the wall.
