Door Details in Masonry

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

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”

Group 1 vs. Group 2 Doors for 6’ 8” door with 3/8” mortar joint u Group 1 (Scheme A) --2 3/16” head --2 3/16” jamb --2 3/16” below floor line w/ 4” block height u Group 2 Scheme A – 1 3/16” head – 1 3/16” jamb – 3 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 - Head Detail (Jamb Sim) Total Head/Jamb =2 3/16” buck 1 1/2” nominal 1 3/16” net wood spline shim space 1/4” finished jamb 1” nominal 3/4” net

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

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

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
