Masonry Construction • Detailer needs to understand • how a door is installed • space available (Masonry Opening) • Masonry Opening (MO) based on • size of masonry units • size of joints • door size • Masonry Openings need to beexact • dimensioning is from masonry to masonry
Modular System • 4” modular system best for masonry construction • Categories or groupings of doors as established by Masonry Design Manual • Group 1 • Door sizes: 2’0, 2’4, 2’8, 3’0 • Group 2 • Door sizes: 2’2, 2’6, 2’10, 3’2 • Don’t mix groups • Either group can be increased by multiples of 4”
--2 3/16” head • 1 3/16” head • --2 3/16” jamb • 1 3/16” jamb • 3 3/16” below floor line w/ 4” block height --2 3/16” below floor line w/ 4” block height Notes: Add 4” for either Group when using 8” block height Group selection will effect foundation design Group 1 vs. Group 2 Doors for 6’8” door with 3/8” mortar joint • Group 2 Scheme A • Group 1 (Scheme A)
buck 1 1/2” nominal 1 3/16” net shim space 1/4” wood spline finished jamb 1” nominal 3/4” net Group 1 - Head Detail (Jamb Sim) Total Head/Jamb =2 3/16”
finished jamb 1 1/2” nominal 1 3/16” net Group 2 - Head Detail (Jamb Sim) Total Head/Jamb =1 3/16” • buck-- none used • shim space--none
Masonry Openings • Group 1 Masonry Width Opening Determination • Step 1--door size + 2* jamb width • Step 2--door size + 2 * 2 3/16 • Step 3(answer)--door size + 4 3/8 = MO • Group 2 Masonry Width Opening Determination • Step 1--door size + 2 * jamb width • Step 2--door size + 2 * 1 3/16 • Step 3(answer)--door size + 2 3/8 = MO
Jamb Anchorage for Group 1 • Bolts directly in grout • Nails at angle Buck must be installed with block work Buck installed with or after block work
Jamb Anchorage for Group 2 Metal anchors embedded in grout No buck, frame must be installed with block work
Pictorial of Veneer Brick w/ Wood Frame • Code usually requires weight of veneer (brick) not be placed directly on wood frame • Lintel used to support brick • angle iron

Pictorial of Metal Door Jamb in Solid Masonry Wall • Jamb must be installed withblock work • Also notice caulking to seal off air infiltration into structure
ASSIGNMENT • Sheet A-8 • Provide Door Type Elevations w/ dimensions • Detail door jambs and header • Use door schedule on page A-10 • Repeat for widow types (must match elevations) HINT: Search Class Architecture Folder
Drafting ExerciseMasonry Door Detail • Profile drawing, use 1/4” diameter anchor bolts • Align both views (In book the alignment is off) • Both details, callout 2-#4 Rebar • Location of dimension for door height is incorrect (HEAD detail), should go to door frame instead of door trim (detail is as per group 2, scheme A) • Finished Head is 1 1/2 x 6 nominal size • There should be no thin lines (JAMB detail) left side of door section
