1. Door Details in Masonry

2. Masonry Construction u Detailer needs to understand –how a door is installed –space available (Masonry Opening) u Masonry Opening (MO) based on –size of masonry units –size of joints –door size u Masonry Openings need to be exact –dimensioning is from masonry to masonry

3. Modular System u 4” modular system best for masonry construction u 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 u Don’t mix groups u Either group can be increased by multiples of 4”

4. Group 1 vs. Group 2 Doors for 6’8” door with 3/8” mortar joint u Group 1 (Scheme A) u Group 2 Scheme A Notes: Add 4” for either Group when using 8” block height Group selection will effect foundation design --2 3/16” head –1 3/16” head --2 3/16” jamb–1 3/16” jamb --2 3/16” below floor line w/ 4” block height –3 3/16” below floor line w/ 4” block height

5. Group 1 - Head Detail (Jamb Sim) buck 1 1/2” nominal 1 3/16” net shim space 1/4” finished jamb 1” nominal 3/4” net Total Head/Jamb =2 3/16” wood spline

6. Group 2 - Head Detail (Jamb Sim) buck-- none used shim space--none finished jamb 1 1/2” nominal 1 3/16” net Total Head/Jamb =1 3/16”

7. Masonry Openings u 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 u 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

8. Jamb Anchorage for Group 1 Bolts directly in groutNails at angle Buck installed with or after block work Buck must be installed with block work

9. Pictorial Jamb Anchorage by bolts

10. Jamb Anchorage for Group 2 Metal anchors embedded in grout No buck, frame must be installed with block work

11. Pictorial of Veneer Brick w/ Wood Frame u Code usually requires weight of veneer (brick) not be placed directly on wood frame u Lintel used to support brick –angle iron

12. Veneer Detail with Wood Frame

13. Metal Door Frame and Jamb Anchors u A variety of jamb anchors u Usually 14 or 16 gauge steel frames

14. Pictorial of Metal Door Jamb in Solid Masonry Wall u Jamb must be installed with block work u Also notice caulking to seal off air infiltration into structure

15. ASSIGNMENT u Sheet A-8 u Provide Door Type Elevations w/ dimensions u Detail door jambs and header u Use door schedule on page A-10 u Repeat for widow types (must match elevations) HINT: Search Class Architecture Folder

16. Drafting Exercise Masonry Door Detail u Profile drawing, use 1/4” diameter anchor bolts u Align both views (In book the alignment is off) u Both details, callout 2-#4 Rebar u 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) u Finished Head is 1 1/2 x 6 nominal size u There should be no thin lines (JAMB detail) left side of door section
