ANSI SDI-A250.11-2012 pdf download Recommended Erection Instructions for Steel Frames
2.2 Back-Coating (see SDI 1 27J for further information)
2.2.1 When temperature conditions necessi- tate the use of anti-freezing agents in plaster or mortar, the inside of the frame shall be coated at the jobsite with a corrosion resistant coating by the contractor responsible for installation. 2.3 Grouting of frames (see ANSI/SDI A250.8 for further information)
2.3.1 Where grouting is required in masonry installations, frames shall be braced or fastened in such a way that will prevent the pressure of the grout from deforming the frame members.
2.3.2 Grout shall be mixed to provide a 4˝ (102 mm) maximum slump consistency, and be hand troweled into place. Grout mixed to a thinner “pumpable” consistency shall not be used.
2.3.3 Standard mortar protection in frames is not intended for thin consistency grout. Steel frames, including fire rated frames, do not re- quire grouting. Grouting is not recommended for frames installed in drywall.
2.4 Assembly of frame/anchor provisions
2.4.1 Follow manufacturers’ recommended procedure for assembly of frame and quantity and spacing of anchors. If not indicated, install anchors at hinge levels and directly opposite at strike jamb.
2.5 Verification
2.5.1 Prior to installation, jobsite personnel shall ensure correct swing, size and labeling.
2.6 Installation tolerances
2.6.1 While this document is mainly concerned with tolerances relating to the manufacturing process, openings will not function properly if the frame is not installed within recognized tolerances. Figure 1 shows examples of the accuracy to be maintained while setting frames.
3 Plumbing and bracing frames 3.1 Wood Spreaders (see Figure 2) The Contractor(s) responsible for installation shall have available a sufficient supply of wood
