ABSTRACT:
A one piece foundation-to-frame member connection for retrofit attachment of a wood building frame member such as a sill plate to a foundation. The connection is particularly useful where the mudsill plate was not initially anchored to the foundation by threaded anchor bolts or other metal connectors or the original anchoring installation was insufficient to give the necessary anchorage to resist uplift of the frame from the foundation by earthquake, high winds, floods or tidal activity. A uniquely S-shaped configured connector having roughly the shape of the front panel of a horse drawn sleigh is preferably attached to the sill plate by lag screws and to the foundation with threaded bolts inserted into epoxy filled drilled holes. All attachments are from the inside of the foundation at a generally horizontal or at a slight angle where the inside face of the foundation is slanted. By forming all fastener openings as slots in curved portions of the connector, the connector may be installed where the inner face of the foundation is vertical or slanted. The connection may be effected where the mudsill plate overhangs the inside face of the foundation to inset several inches and all points in between.
