The Seven Steps
Masonry Partitions
Purpose
To secure masonry partitions.
Recommendation
Install braces to the structure above.
Caution
- Unreinforced masonry partitions are extremely hazardous and should be removed if possible.
- When anchoring to post-tensioned slab, locate and avoid reinforcing.
Supplies Required
- Clip angles—3″ x 4″ x 1/4″ x 1′-3″
- Expansion bolts—1/2″ diameter (for concrete)
- Channel (appropriate for wall width)
- Angles—4″ x 4″ x 1/4″
- Angles—3″ x 3″ x 1/4″
- Drive pins—5/32″ diameter (for steel)
- Lag bolts—3/8″ diameter x 3″ (for wood)
- Wood blocking—4x
- Framing clips—Simpson A35
Installation
Concrete Building Installation
- Weld 3″ angle braces at 4′-0″ on center to continuous channel over wall.
OR
Install clip angles at 4′-0″ on center each side of the wall. - Attach the angles to the structure above with expansion bolts. Use two bolts for each clip angle.
Steel Building Installation
- Install 3″ angle braces at 4′-0″ on center.
- Attach angle to the structure with drive-pins.
- Weld continuous 4″ angle on each side of the partition to 3″ angles.
Wood Building Installation
- Position 4x blocking between joists with framing clips.
- Install continuous 4″ angle on each side of the wall.
- Attach angles to new 4x blocking with lag bolts at 4′-0″ on center.
