Abstract:
1. A modular construction panel, comprising: a panel having a height, opposed first and second faces, and opposed ends, each end being generally vertical; a keyway receiver integral with the panel adjacent one of the panel ends; and a keyway spline integral with the panel adjacent another of the panel ends; wherein the keyway receiver includes: wherein a generally vertical wall extends from the keyway receiver first offset face and another generally vertical wall extends from the keyway receiver second offset face; the wall extending from the keyway receiver first offset face, the wall extending from the keyway receiver second offset face, and the proximal face being generally parallel; the wall extending from the keyway receiver second offset face being inset toward the proximal face from the wall extending from the keyway receiver first offset face; wherein the keyway spline includes: wherein a generally vertical wall extends from the keyway spline first offset face and another generally vertical wall extends from the keyway spline second offset face; the wall extending from the keyway spline first offset face, the wall extending from the keyway spline second offset face, and the distal face being generally parallel; the wall extending from the keyway spline second offset face being outset toward the distal face from the wall extending from the keyway spline first offset face.
