4. Once the frame has been properly set, and securely anchored at the head and sill, place the intermediate wind load anchor flush with the face of the slab and
with the side of the jamb mullion as shown in Figure 48 below. Refer to the final approved shop drawings for exact anchor placement and minimum bolt edge
distance requirements.
5. Apply an anchor alignment screw ( STK6 #12-14 X 1 ” HWH SMS ZC TEK 3) to hold the anchor temporarily in place. This fastener must be removed prior to
final anchor attachment.
6. Ensure the anchor is pressed firmly against the face of the floor slab and match drill the jamb mullion through the center of two of the slots in the anchor to
prepare the mullion to receive rivnuts. Choose the set of slots which will allow the anchor bolt to be placed a minimum of 1” from the back of the mullion to
clear any steel reinforcement that may be required on the project. For steel reinforcement, anchor configuration, rivnut, bolt, and hole size requirements,
refer to the final approved shop drawings.
7. Remove the temporary fastener and anchor and apply two rivnuts into the match drilled holes in the jamb per the rivnut manufacturer’s instructions. See
Figure 49.
8. Attach the anchor to the jamb, separating it from the mullion with shims, using bolts, and flat and spring lock washers as required. See Figure 49.
