Anchoring Systems New masonry Stud walls Existing masonry

Anchors for Frames Proper anchoring is vitally important for proper performance of door opening. Anchors are designed to match the wall construction. There are variations in design between manufacturers, but performance remains the same. Additional information in HMMA 820 Hollow Metal Frames.

Anchor Spacing of Wall Anchors Welded Frames Wall anchor locations and quantity are in addition to floor (base) anchors, when required. Required anchor quantity differs with wall construction and height of frame. Masonry walls are frames with expansion bolt anchors. Requirement also specifies spaces of these anchors.

New Masonry Walls Installation of a hollow metal frame in masonry. Check to make sure all angles are 90 degrees before securing frame. As a wall is laid up, locate anchors at the hinges in hinge jamb and at corresponding position in strike jamb.

New Construction Masonry Walls 3 different versions of Masonry Anchors

Steel Stud Walls Zee-shaped anchor is welded to both rabbets inside the jamb. Steel studs are mechanically fastened to exposed flange through throat of stud. Due to irregularities in wall construction width, it is strongly recommended that frames for stud wall have a throat dimension 1/8 greater than the dimensioned wall thickness

Steel Stud Walls Position vertical steel studs in frame throat opening in accordance with architect s details. Attach vertical steel studs to floor and ceiling runners and fasten to steel stud anchors with mechanical fasteners.

Steel Stud Walls Follow steel stud manufacturer s recommendation on thickness and general construction technique to ensure a solid, stable opening is achieved.

Steel Stud Walls Caution must be taken to ensure any fasteners applied through face of studs or any construction will not increase wall thickness. Continually check squareness, plumbness, alignment and twist in frame as wall progresses.

Wood Stud Walls Wood stud walls can be constructed after frame is set or prior to setting frame. When constructing the wall after the frame is set, follow guidelines for steel stud walls. For constructing wall prior to setting frame, follow these guidelines: Rough Stud Opening: width of opening must be overall frame width plus 1/2. Opening height must be overall frame height plus 1/4.

Wood Stud Walls Place frame in rough stud opening. Bend anchor tabs around stud, leaving desired clearance between frame return and stud, for inserting finished wall material.

Wood Stud Walls Square frame at top corner and nail top anchor to stud on One Jamb Only. Recheck level, plumb and alignment of frame at other corner and continue to nail balance of anchors to studs. Repeat same process for opposite jamb. It is extremely important that heads of fasteners are considered to ensure that combined thickness of wall stud, fastener head height and finished wall material does not exceed designed wall thickness.

Base Anchors Fixed Base Anchors Fixed Anchor: welded to base of jamb, typically secured to floor by mechanical fasteners. Shimming must be used if floor is not level. Not to be used in existing masonry, pre-framed stud walls or slip-on dry-wall frames. For existing masonry or concrete walls, additional expansion anchor reinforcement provided. For pre-framed stud walls or completed dry openings, an additional base anchor is included.

Base Anchors Adjustable Base Anchors Adjustable anchor: designed for use where there are significant irregularities from level, an intended slope in floor, or surface toppings, such as terrazzo are used. Cannot be used in prepared openings or slip-on knock-down dry-wall frames.

Existing Masonry Walls Clearance between existing wall and frame is critical. Size frame accordingly to dimensions taken, providing 1/4 clearance around frame.

Existing Masonry Walls Insert mechanical fasteners through frame soffit into existing wall. Shim, by others, behind anchors, above bolts to ensure a plumb frame. Make sure to keep frame square during installation with the use of spreaders. Tighten bolts. Caulk between frame and wall.

Drywall Framing Systems Type of stud walls Drywall Slip-on frames

Drywall System Types of Stud Walls Type of stud wall constructions: Steel Stud Wood Stud

Hollow Metal Frames for Stud Walls Regardless of whether the wall is constructed of either wood or steel studs, there are two hollow metal frame designs to consider. Either frame design is installed into commercial drywall framing systems. The difference is in the method of installation and basic product features. Design and installation processes may vary by manufacturer: Types of Frame Product Designs and Installations Conventional HM frames are anchored to the floor structure--plumbed, squared and directly to the steel/wood studs prior to attaching the drywall. These frames can be supplied to the jobsite as either KD (knock-down) or as welded assemblies Conventional Frame Installation Installed during wall construction Typical anchor for conventional applications

Hollow Metal Frames for Stud Walls HM Drywall Slip-on frames are installed into a rough opening of a pre-erected and finished steel/wood stud wall. After the frame is slid into the wall, it is anchored and squared. Slip-on Frame Installation Installed after wall is complete and finished Typical anchor for slip-on applications

Stud Wall Construction Construction Notes: 1. Follow stud manufacturer s recommendations: 20 gage thickness at door openings Website located at www.ssma.com/ The wall construction methods are critical. The security, integrity and long term operation of the finished opening (frame, door and hardware) depends greatly on the method and quality of the wall studding along with the application and finishing of the drywall board. In most cases, door operational issues relate directly to compromised wall construction and deficient frame installation methods. It is critical that wall framers follow the stud manufacturer s material recommendations and professional commercial construction techniques. Recommendations are for minimum #20 gage steel studs at the perimeter of all hollow metal door and window openings.

Stud Wall Construction Construction Notes: 1. Follow stud manufacturer s recommendations: 20 gage thickness at door openings 2. Follow general construction technique must be followed to ensure a solid, stable opening. Proper fasteners Proper spacing For steel stud walls, the vertical studs (both jack and king studs) adjacent to the door or window opening must extend the full height of the wall from top plate to the bottom plate. Studs must be properly spaced and assembled with proper screw fasteners. For wood stud walls, the vertical king studs must extend the full height of the wall from top plate to the bottom plate. As with steel stud walls, the wood studs must be properly spaced and assembled with proper nail fasteners.

Drywall Slip-on Frames Installation Process (5 steps) 1. Slide header in place over wall approximately in center of opening. Step #1

Drywall Slip-on Frames Installation Process (5 steps) 1. Slide header in place over wall approximately in center of opening. 2. Install one jamb by sliding it over wall at top. Push bottom of member until it is approximately vertical. 3. Install other jamb in similar manner. Frame should be installed with all excessive rough opening clearances thrown to hinge side. Weight of door will tend to cause movement, within opening, toward strike jamb. Step #1 Step #2 Step #3

Drywall Slip-on Frames Installation Process (5 steps) 5. Plumb and square opening, check jambs for twist. Anchor the base anchor of each jamb Adjust the compression anchors located in the frame soffit near the top of each jamb. Compression anchor design may vary with frame manufacturers Step #5 Compression anchor adjusting screw Typical Detail Note - Some installers prefer to hang the door at this point, permitting the door to aid in performing this function.

Adjustable Compression Anchor An adjustable compression device is normally located near the top of each jamb. This anchor is used on slip-on dry wall frames and in conjunction with slip-on dry wall base anchors. Consult manufacturer s literature for direction to turn compression anchor. The compression anchor must be hand tightened. Do not use screw gun. Typical compression anchor details See figure 19D

Additional Information Field Splice Masonry clean up Hanging and adjusting the door Shimming and adjusting Technical Tips Grouting of frames Undercuts Field finish painting

Field Splicing Some frames are oversized to the point where they exceed the shipping and handling limitations. Those frames are supplied from the manufacturer with predesigned field splicing connections. Depending on architectural specifications, the splice joints can either be mechanical or welded connections. It is the responsibility of the installing contractor to: Install all units and join connections together. Complete mechanical connections. If connections are welded, all joints must be welded, cleaned, and finished. All joints must be prime painted immediately after weld finishing to avoid rusting.

Field Splicing Required on oversized opening Due to shipping and handling limitations If splice joints are welded, welds must be ground smooth and immediately cleaned and prime painted. Typical splice detail See figure 20

Masonry Clean up - CAUTION Acid washing of adjacent masonry Protect all hollow metal Immediately clean to prevent rusting If exposed to an acid wash All primed or painted steel surfaces must be thoroughly cleaned Pay particular attention to hidden areas such as those under glazing stops. NOTE: Rusting resulting from improper protection and clean up

Hanging and Adjusting the Door Shimming and Adjustment After the door and hardware is installed, it is the responsibility of the installing contractor to make final adjustments to the opening. Adjustments are usually accomplished through shimming.

Technical Notes Published as supplements to technical information and standards

Tech Notes Grouting Frames Frames in masonry walls are often specified to be grouted full during the installation process. Proper grouting of frames will enhance durability and sound deadening, but grouting is not required on fire rated hollow metal door frames. The grouting process is the responsibility of the installing contractor. Only mortar grout is recommended. If anti-freezing agents (or other caustic agents) are added to the mortar grout, it is the responsibility of the installing contractor to back coat the hollow metal frames with corrosion resistant material prior to installation. Back coating prevents the extremely aggressive rust created by the anti-freeze agents.

Tech Notes Grouting Frames Grout - a substance used to fill the interior of frames in masonry applications. MORTAR GROUT: Recommended PLASTER GROUT: Not recommended Responsibility of installing contractor Enhances frame durability and sound deadening, Not required for fire-rated frames Appendix 1 Caution Notice: 1. When dictated by temperatures, anti-freezing agents for mortar may be recommended by specifications. These agents can adversely affect metal, and all surfaces in contact with the grout must be coated with a corrosion resistant material by the installing contractor. 2. Silencer must be installed prior to grouting

Tech Notes Undercuts UNDERCUT The distance between the bottom of door and the bottom of frame. The formula in which to determine the undercut is derived by adding the total sum of the following : Floor Clearance Floor Covering Thickness Threshold Height Jamb Extensions Height (if required) Undercut Appendix 2 Incorrect door undercuts and jamb extensions create installation problems and interferences which can be avoided.

Tech Note Painting Hollow Metal Products The Contractor s Responsibility 1. As we covered earlier in this training session, jobsite storage of hollow metal is critical in avoiding damage and onsite rusting. 2. What appears to be obvious paint defects or problems could have varying causes and require different solutions. 3. It is the responsibility of the installing contractor to lightly sand all factory primed surfaces with a fine grit sand paper or emery cloth. 4. Hollow metal is a fabricated and welded architectural component. The finish paint gloss rating in excess of 20º (on a 60º gloss meter) is not recommended. The gloss of the field applied finish paint, compounded by the ambient light sources, could have a dyer effect on commercial fabricated metal finishes. Appendix 3

Transom, Sidelights and Window Frames Exterior Locations Installing contractors responsibilities 1. Install frames in accordance with NAAMM/HMMA 840-07 2. Space around perimeter edge of glass and steel frame must have a continuous bead of sealant. 3. Fully caulk all joints at meeting surfaces of rabbets. 4. Threads of screws holding glazing stops must be caulked prior to inserting and tightening HMMA-820 TN03-07
