EFCO S5500 Outside Glazed - Manual (Page 16)

EFCO CORPORATION 6/2012 PART NO. Y550
Series 5500 Outside Glazed Installation Instructions
Section III: Typical Anchorage Methods
STEP #6 INSTALL FRAME COMPONENTS – WELDED DEAD LOAD ANCHORS
For installations with multi-spans, set the frame into the opening as instructed in previous steps, and
apply the dead load anchors to the jambs with temporary screws at the proper location at the floor
slab. Refer to the approved shop drawings for more information. When the frame is properly aligned,
and is level and plumb, weld the anchors to the building structure. Match drill the mullion through a
set of holes in the anchor.
NOTE: The holes must be a minimum of 1” from the back of the mullion in order to clear any steel rein-
forcement located inside the system, as may be required on a job specific basis.
Use a bolt with a flat washer at the bolt head end. At the nut end of the bolt, use a flat washer then a
spring lock washer next to the nut as shown. Shim at each bolt as indicated. The nut must be tight-
ened sufficiently to completely compress the spring lock washer, but not to deform the mullion. The
threads of the bolts must be staked or Loctite must be used to prevent the nut from loosening from
the bolt. Refer to the approved shop drawings for anchor locations, bolt sizes, welding requirements,
and other job specific information.
NOTE: For special instructions regarding wind load anchors see page 18, step 7.
