CA 2222820

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, and a hole on the main body configured for receiving the fastener. The plate is configured so that the hole is angled relative to a vertical axis of the plate for accommodating threads of the fastener so that the fastener is maintained in a generally perpendicular orientation to the main body upon the engagement of the threads of the fastener in the hole. In the preferred embodiment, the threads of the fastener have a helix angle, and the hole, which is formed in a conical depression in the plate, is angled at the same angle as the threads of the fastener.

Cette invention concerne un répartiteur de contrainte à utiliser avec une fixation filetée servant à assujettir un isolant relativement mou à une base rigide telle qu'un platelage de toit. L'objet de l'invention comporte un corps principal généralement plan, percé d'un trou pour le passage de la fixation filetée. Il est configuré de manière que la paroi du trou forme un angle par rapport à son axe vertical et puisse épouser les flancs du filetage pour maintenir la fixation filetée sensiblement à angle droit par rapport au plan du support de vissage. Selon une variante privilégiée, la fixation utilisée a des filets coniques et le trou, formé dans une dépression conique du répartiteur, une paroi inclinée selon le même angle que les filets de la fixation filetée.
