Abstract:
A take-up fastener is disclosed for fastening a level in a frame construction to the level below so as to resist upward forces generated by wind and other sources on the framed construction. The take-up fastener in general includes a take-up plate, or washer, fastened to a portion of the upper level and a take-up screw fit through the take-up plate and fastened to the adjacent level below. Once the take-up fastener is fully assembled, the take-up plate includes a pair of tabs which are capable of engaging threads on a take-up screw in a way that allows one-way motion of the take-up screw relative to the take-up plate. In particular, the take-up plate can move downward relative to the take-up screw, for example on constricting of the wooden members to which the take-up plate is affixed. However, the engagement between the take-up plate and take-up screw prevents movement of the take-up plate upward with respect to the take-up screw, for example upon an upward load due to wind or other external force.
