Abstract
A foundation haunch assembly used for attachment to a foundation wall and a method of making the haunch assembly using a concrete block machine. The haunch assembly includes a concrete haunch having an upper portion, a center portion and a lower portion. The upper portion of the haunch includes a flat top surface adapted for receiving a portion of a pre-cast concrete slab, stairs, stoops, poured in place concrete slab or other building structure thereon. Also, the upper portion includes an internal horizontal metal support rod along the length thereof. One end of the support rod is threaded to one end of a threaded coupling. The foundation haunch assembly also includes a variable length foundation bolt with a threaded end threaded into an opposite end of the threaded coupling. The foundation bolt is adapted for receipt through a hole in a portion of a vertical foundation wall. An opposite threaded end of the foundation bolt is attached to a nut. The nut is used for tightening and securing the foundation bolt and the concrete haunch to a side of the foundation wall.
