Caution

Secure ALL pipes that are used for fire protection systems.

When anchoring to post-tensioned slab, locate and avoid reinforcing.

Recommendation

Install pipe brackets as indicated in the following figures:

Supplies Required

  • Angle—2″ x 2″ x 1/8″
  • Lag bolts—1/4″ diameter x 3″ (for wood)
  • Expansion bolts—3/8″ diameter (for concrete)
  • U-bolts—1/4″ diameter (for concrete)
  • Flexible connections to equipment

  1. Install angle braces (cope as required) with lag bolts into wood joists.
    OR
    expansion bolts to concrete.
  2. Attach each angle brace to the pipe with a U-bolt.
  3. Locate at 90x turns in pipe where the pipe is continuous.
  4. Place bracing brackets at 16′ on center along unbraced runs of straight pipe.
  5. Add flexible connections.

Note

  • Brace fuel, oil, gas, or compressed air pipes that are greater than 1″ in diameter.
  • Do not use pipes to support other pipes.
  • Wall openings for the pipe sleeves must be at least 2″ larger than the pipe in fire-resistant systems. Consult a building official for the proper fill material in the wall gap.
