Abstract
A connector arrangement for joining adjacent chord bar reinforcements in wall panels for prefabricated tilt-up concrete buildings. The chord bar connection is comprised of a plurality of chord bars welded to a steel plate cast into the concrete of a prefabricated wall. Adjacent walls are connected by bolts passing through the metal plates attached to the cast in concrete chord bars. The bolting arrangement allows free movement of adjacent panels during dimensional changes caused by temperature and moisture variations in the concrete.
