Protective shield for utility opening in a building framing member

摘要

A protective shield overlies the wall panel supporting face of a building framing member and prevents a wall panel fastener of the self-drilling type from entering a utility service opening provided in the framing member. The protective shield is formed of a material and thickness which provides substantially greater resistance to penetration by the self-drilling fastener than the resistance of the wall panel supporting face of the framing member so that the fastener fails or the presence of the protective shield is sensed by the construction mechanic prior to entry of the fastener into the framing member. The protective shield includes integral fastening clips which project generally perpendicularly from the opposed side edges thereof and are adapted for resilient clamping engagement on the building framing member to mount the protective shield in juxtaposed relation with the face of the building framing member and in overlying alignment with the utility service opening. The integral fastener clips on one side of the protective shield have inwardly bent teeth formed thereon to grip the building framing member. An outwardly bent lip is provided on the fastening clips at the other side edge of the protective shield to provide a resilient outward camming of the integral fastening clips as the protective shield is attached to the framing member.
