Roof insulation fastening system

摘要

A roof insulation fastening system employs a fastener and a compression plate with a tube which interacts with the compression plate to permit the plate to vertically move relative to the head of the fastener when the adjacent area and/or plate is subject to excessive compression. The tube includes a retainer shoulder and a pair of tabs wherein the plate captures the tube. The tube includes a throat and a tapered portion with a throughbore. The fastener is inserted into the tube and secured in place so that the head is retained at the intersection of the throat and the tapered portion and the shank is secured into the roofing substrate.

主权项

1. A tube seatable in a roofing compression plate for receiving a fastener comprising:
a circumferential retaining flange; a sleeve extending from said flange and defining a pair of cutouts each surrounding a resilient tab projecting toward said flange and having a shoulder spaced from the underside of said flange and interiorly forming a throat with an interior annular shoulder adapted for engagement by a fastener head; and a tapered portion integrally extending from said sleeve and tapering toward a distal tip, a throughbore extending from said throat and dimensioned for receiving the shank of the fastener, a plurality of angularly spaced slots extending to said tip to permit limited flexure in said tapered portion.
