Abstract
There is provided an improved wall construction including a vertical mullion and a horizontal member. The horizontal member is provided with longitudinally extending screw splines. The members may be assembled in the known shear block method, or in a known screw spline system, or further in accordance with the present invention the members may be assembled in accordance with an improved shear pin system. The shear pin system employs a shear pin which joins the horizontal member to the vertical mullions. The vertical mullion is prepared for the attachment of a horizontal member by forming holes to receive the head of a shear pin, and the horizontal member is prepared by the insertion of the shear pins into screw splines formed in the horizontal member. The horizontal member is then installed on the vertical by installing the head of the shear pin into the hole previously drilled in the vertical mullion, and then tapping the horizontal downward until the shear pins bottom in the holes.
