Reinforcement bar support system

Abstract

A reinforcement bar support system transfers forces perpendicular to a wall to a surrounding frame while permitting movement of the wall with respect to the frame in the direction of the plane of the wall and in the vertical direction. A bar is built into the wall. The apparatus includes a brace that is attached to the frame and a face that projects from the brace. Flanges extend outwardly from the face to receive the bar and limit movement of the bar with respect to the frame in the direction perpendicular to the wall.
