INSERT AND METHOD FOR ANCHORING IN A CORED PANEL

摘要

An insert is configured for anchoring within a cored panel and has a wide flange on one end, a sacrificial cover and threaded pin on its opposite end and a nut captured therein. The panel is prepared by forming a countersunk hole therein and filling or coating such opening with an adhesive. The insert is fitted into the hole such that the flange is positioned against one surface of the panel while the sacrificial cover and threaded pin protrude from the opposite surface. A screw fixture is threaded onto the threaded pin to maintain the insert in place while the adhesive cures. Subsequent removal of the screw fixture and sacrificial cover completes the anchoring process and exposes the nut that is captured within the insert for receipt of an appropriate fastener.

主权项

1. A wide flange insert for providing an attachment point for attaching and anchoring a component to a panel, comprising:
a tubular wide flange body including a tubular shaft portion having a first outer diameter, an inner bore with an inner diameter, first and second ends, an enlarged flange formed at the first end of the tubular wide flange body and having a second outer diameter larger than the first diameter, and a counter bore formed at the first end of the inner bore of the tubular wide flange body; a generally cylindrical sacrificial cover having first and second ends, the first end of the sacrificial cover being connected to the second end of the tubular wide flange body; a threaded pin connected to and extending from the second end of the sacrificial cover; a tubular nut including a tubular shaft portion having an outer diameter smaller than the inner diameter of the tubular wide flange body, and an enlarged flange formed at an end of the tubular nut, the tubular nut being disposed within the tubular wide flange body with the enlarged flange of the tubular nut disposed in the counter bore formed at the first end of the inner bore of the tubular wide flange body; and a retainer cap fixedly attached over the enlarged flange formed at the first end of the tubular wide flange body, the retainer cap being configured to retain the tubular nut within the inner bore of the tubular wide flange body.
