Abstract: An anchor and stress plate assembly adapted to secure an insulation layer to the deck of a roof without penetrating the lower surface of the deck which is formed either of relatively soft or hard decking material. The anchor is provided with a flanged head and a shank whose leading section takes the form of an auger screw having a root which tapers toward the tip and a threading about the root whose crests are of approximately uniform diameter. When the anchor is turned into soft decking material, the tapered root of the auger screw then acts to pack this material into a dense mass in the region surrounding the screw to enhance the holding power of the anchor. In hard decking material, a hole must first be drilled therein to receive the auger screw whose root when the anchor is turned in fits within the hole and whose crests then cut a thread in the hole wall to securely retain the anchor.

Abstract: A load-bearing square plate usable in conjunction with an anchor bolt to firmly secure a layer of thermal insulation material to a roof surface to prevent the layer from being blown away as a result of strong updrafts. The plate has a center hole for receiving the shank of the anchor bolt to be driven by a hammer into the roof. The plate is embossed to define both a raised hub which surrounds the hole to catch the head of the hammer when it drives in the bolt and thereby prevent overdrive thereof, and a plate-reinforcing pattern to resist flexure thereof omnidirectionally. This embossed pattern is constituted by a four-sided marginal frame adjacent the edges of the plate, a star formed by radial spokes of progressively diminishing width extending from the hub to the corners of the frame, and a cross formed by short ribs lying between the radial spokes and extending from the hub to the midpoints of the frame sides.

Abstract: A non-displaceable, self-righting shim for use in any application where critical alignment is required of adjacent vertical elements. The shim presents an elongated central opening including a large upper portion and a small lower portion, and a slot having an exit end communicating with the central opening and an entrance end at the perimeter edge of the shim. The weight distribution of the shim relative to the large upper portion is such that the shim will hang in a normal upright position with the small lower portion and the slot below the large upper portion. The arrangement assures positive placement of the shim once installed; avoids loosening and fall-off of the shim which may be caused by thermal expansion and contraction of the shimmed element and/or by vibrations associated with the adjacent vertical elements; and eliminates the need for holding the shim in position while securing the fastener.
