CA 2243342

A stress plate for use with a threaded fastener for securing relatively soft insulation to a solid base, such as in a roofing environment, includes a generally planar main body with an underside, an aperture on the main body configured for receiving the fastener, and a sleeve circumscribing the aperture and depending from the underside a sufficient distance to receive the fastener and maintain the fastener perpendicular to the plate, especially when the plate is located intermediate the fastener ends. In the preferred embodiment, the fastener is threaded with a defined pitch of the thread, and the sleeve is dimensioned to span at least one pitch of the fastener.

Plaque de contrainte utilisée avec un dispositif de fixation filetée de façon à fixer un matériau isolant relativement souple à une base solide, comme sur une toiture. La plaque comprend un corps principal généralement planaire avec une face inférieure, une ouverture pratiquée sur le corps principal configurée pour recevoir le dispositif de fixation, et un manchon entourant l'ouverture et dépendant depuis la face inférieure à une distance suffisante afin de recevoir le dispositif de fixation et de le maintenir perpendiculaire par rapport à la plaque, surtout lorsque la plaque est située entre les extrémités du dispositif de fixation. Dans une des réalisations préférées, le dispositif de fixation est fileté avec un pas de filetage défini, et le manchon est de dimension voulue pour traverser au moins un pas de l'élément de fixation.
