STRAPPING

CORNER & ANGLE STRAPPING

PRE-FORMED CORNERS

• Wrap around corner and overlap two webs on adjacent straight block

• Use at least 2x4 dimensional lumber

JOBSITE ASSEMBLED ANGLES

• Use full height OSB or plywood wide enough to cover two webs each side of angle

• Attach 2x lumber height of wall in corner on both sides

WINDOW & DOOR STRAPPINGWINDOW & DOOR OPENINGS

• For metal or vinyl, follow manufacturer’s recommendations

• For external wood, picture frame wrap both sides

• For internal wood, attach to EPS with long screws & plastic washers

• Brace wood bucks vertically & horizontally every 18” with 2x4 or wider

ARCHED OPENINGS

• Brace horizontally at bottom of arch, vertically in center, and two pieces horizontally

• Brace bottom of window like standard opening but without corner bracing

SILL OPENING

• Less than 4’ – drill one 5” or larger hole in center

• More than 4’ – drill one 5” or larger hole every two feet

T-WALL & PILASTER STRAPPING

• Strap both the same

• Use 2x6 or larger lumber to cover two webs each side

• Additional support needed for pilaster end cap

NON STANDARD JOINT STRAPPING

Any vertical joints that are too close together or not offset properly

RADIUS WALL STRAPPING

• Fasten 1/8” hardboard strips to inside and outside radius flush to bottom of each course

• Pieces must be tight and aligned at top prior to fastening

• Install bracing on the radius

STANDARD BRACING

• Provides access to upper courses

• Keeps wall aligned prior to and during the pour

• Typically installed on inside of wall structure

• Spacing depend on height & core size of wall

• Consider safety regulations, code compliance, and engineering requirements when choosing bracing system

TALL WALL BRACING

• Tall walls are common construction features

• Numerous scaffolding companies manufacture tall wall bracing for the ICF industry

•Considerations:

•Safety regulations

•Code compliance

•Engineering requirements
