Abstract
A device for compensating for the natural shrinkage of building materials includes a hinged expander mounted on an elongate base plate. The base plate includes a plurality of spaced apart teeth on each longitudinal end that define a notch between each pair of adjacent spaced teeth. The hinged expander included two leafs that are joined at an apex in a hinged relationship. Each leaf has an outer edge configured for receipt within a notch in the base plate. Apex is biased in a direction away from the base plate. The teeth prevent outward movement of the leaf edges while permitting inward movement. The base plate is securely fastened to a first building member. A fastener is longitudinally fixed relative to a second building member and the apex of the hinged expander but not fixed longitudinally relative to the base plate and first building member.
