Tying bar for concrete joints
First Claim
1. An improved dowel or tying bar for transferring stresses across a joint between concrete structures and accommodating for shrinkage or expansion the concrete structures, the joint defining an axis, the improved bar having sides and a first and second end, the sides of the bar embedded in the concrete structures and arranged across the joint in a direction substantially perpendicular to the axis defined by the joint, and the bar further having a resilient facing attached to at least one side of the bar to provide for movement of the concrete structures in relationship to the bar in a direction substantially perpendicular to the resilient facing and substantially aligned with the joint axis.

Abstract
An improved dowel or tying bar and joint construction for transferring stresses across a joint between concrete slabs or structures and accommodating for shrinkage and expansion of concrete. The bar has a resilient facing attached to at least one side of the bar so that the concrete slab or structure can move in relationship to the bar in a direction substantially perpendicular to the resilient facing. The bar is arranged across the joint in a direction substantially perpendicular to the axis defined by the joint.
