Stucco sheathing fastener
First Claim
Patent Images
1. A building structure system for retrofitting stucco sheathing to improve resistance to seismic and other loading forces imposed on the sheathing comprising:
- a wood building frame structure;
one or more layers of stucco sheathing applied to the structure and;
a plurality of metallic fasteners for securing a pre-determined portion of the stucco sheeting to the wood building frame, wherein each fastener comprises;
a fastener with body portion of a pre-determined axial length having a hexagonal head at one axial end of the body, a screw threaded portion at an opposite axial end of the body, and an unthreaded shank portion extending between the screw head and the threaded portion, wherein the unthreaded shank portion has an axial length in excess of one inch (1″
) and wherein at least between three-eighths (⅜
″
) inches and one-half inch (½
″
) of the axial length of each unthreaded fastener shank extends entirely through the stucco sheathing and into the building frame structure whereby lateral forces imposed on the stucco sheathing are transferred from the sheathing into the building frame, and wherein the axial length of the unthreaded shank portion is approximately one and one-eighth inches (1⅛
″
) in length and the entire axial length of the fastener is approximately two and one-quarter inches (2¼
″
) in length and wherein each fastener body is comprised of a metal material that has been normalized to increase the ductility of each fastener.
