Horizontal Shore Components
|
• Wall Plates: transfers weight laterally
• Struts: supports wall plates, not greater than 12” f/top & bottom of wall plates • Pipe Screw Jack: can use instead of wood strut (4”x4”=18000 lbs., 6”x6”=36,000 lbs.) • Wedges: fill gaps • Gusset Plates: used at joints • Diagonal Bracing: on each side of shore in an “X” • Midpoint Brace: use when 4”x4” struts > 8’ or 6”x6”>12’ |
|
|
Horizontal Shore Assembly
|
• Measure & cut wall plates
• Mark wall plates for struts • Attach cleats to aid strut placement • Measure for struts deducting pressurization devices • Cut struts • Position shore & align ends of wall plates • Install & pressurize bottom strut • Install & pressurize top strut • Install diagonals • Install & pressurize middle strut (if needed) • Nail gusset plates & cleats to secure joints |

Window & Door Shore Components
|
• Header: 4”x4” generally used (for every 1’ span, 1” wood needed) may need to stack lumber if span > 4’
• Sole Plate: supports weight being transferred • Posts: no longer than 8’ • Wedges: fills gaps • Gusset Plates: 12”x12”x17”x3/4” triangles • Cleats: secures joints • Diagonal bracing: locks shore together, make an “X” (if no access needed)/Window & Door Shore Pre-constructed Method, • Measure & cut header & sole plate • Measure overall height to be shored & deduct header, sole plate & pressurizing devices • Measure & cut vertical post • Install posts between ends of header & sole plate • Nail triangle gusset plates on both corners & sides • Place shore in opening • Pressurize w/wedges between header & opening • Pressurize header & sole plate w/wedges on both ends of header & sole plate • Install shims • Install diagonal braces (if not used for egress) |
