  1. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In For commercial & residential Wood Frame Deck Construction

  2. Construction Detail • Decks were created to expand the living space of the home • Existing house building techniques were used to construct decks • Frame consisted of joists nailed together, resting on two parallel supports

  3. Assumptions: • The house has a Rim Joist, • The Rim joist was properly installed • The Rim Joist is capable of resisting years of “pull out” or lateral force HOW IS A RIM JOIST USUALLY INSTALLED?

  4. Typical detail for installing rim joist

  5. OSB RIM BOARD INSTALLATION INSTRUCTIONS • Connection requirements:Connecting to joistFace-nail rim board to each joist with two (2) 8d nails, one into top and bottom flange. Connecting to plateToe-nail rim board to wall plate with 8d nails at 6" o.c. or 16d nails at 12" o.c.Connecting to subfloorAttach floor sheathing to rim board per building code or structural panel manufacturer's specifications. (Closest on-center nail spacing is 6".) For lateral seismic or wind shear transfer of up to 200 PLF, use 8d nails at 6" o.c.Connecting to other rim boardsFace-nail rim boards together at corners with three (3) 8d nails.

  6. I Joist • Attaching ledgersTo attach a ledger, use 1/2" through bolts with nuts and washers or 1/2" lag screws (minimum length of 4") with washers. Maintain 2" edge distances on ledger and rim board. When using lag screws, drill 5/16" lead holes in rim board and 1/2" holes in ledger. Caulk holes with high quality caulking immediately before inserting the bolts or lag screws. Caution: The lag screw should be inserted in a lead hole by turning with a wrench, not by driving with a hammer. Do not over-torque lag screws. Over-torquing can significantly reduce the lateral resistance of the lag screw.

  7. I Joist/ Rim Board Installation • “Attach rim board to each I-joist by driving one 8d common or ring-shank nail through the face of the rim board into each flange of the I-joist.”

  8. Toe Nail Detail • Attach Rim Board to top plate of wall or foundation sill plate with 8d common or ring-shank nails, toe nailed at 6" on center.

  9. In these conditions, would you be thinking about the future deck that may be attached to this framing?

  10. Add Deck Ledger • Attach ledger to Rim Board with 1/2" lag bolts. Lag bolt should be of sufficient length to fully penetrate rim board.

  11. Lateral anchor- THEORY: • Bolt the rim joist to house floor joist • Designed to keep nails from pulling out • Bolts in floor joist are in Shear, not Tension (pullout)

  12. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In Based on the Concept of “SHEAR STRENGTH”

  13. Lateral Anchors • Provides resistance to lateral force • Specifically designed to counter “pullout force” • Visible evidence of solid connection • Easy for inspector to verify connection • Versatile; multiple installation configurations

  14. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In RISK ASSESSMENT FOR RESIDENTIAL DECKS 1. IRC 2000 Safety Code Compliance 2. Band Board Pullout & Deck Collapse 3. Handrail Resistance to Lateral Loads 4. Consistent Level of Quality - house to house - site to site - state to state

  15. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In IRC 2000 SAFETY CODE COMPLIANCE Current residential deck construction methods and materials do not comply: * “Decks must be designed for lateral forces generated by a live load on the deck…” * “Deck handrails must resist a minimum lateral force of 200 lb with a factor of safety of 2.5…”

  16. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In Bandboard Pullout and Deck Collapse occur because the attachment is not designed to resist the forces generated by a potential capacity live load on the deck.

  17. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In Handrail catastrophic failure occurs because the handrail post attachment is not designed to do it’s job: to guard the outside edge of the deck and protect people.

  18. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In Quality & Consistency vary by: * individual personnel * subcontractors * project supervision * State standards * the day of the week

  19. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In The DECKLOK Bracket System is the engineered solution to the risks associated with the design and construction with wood; houses, decks, atrium landings, pool enclosures, gazebos… …Design it - DeckLok will lock it in!

  20. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In The DECKLOK Bracket System provides: * Certified IRC 2000 and IRC 2003 Safety Code Compliance * Conformity with current construction methods and techniques * Uniform Design and Application * Consistent Level of Quality in the Field

  21. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In Certified Testing results: * The DECKLOK Bracket System resists the maximum live lateral load on a typical deck. * The DECKLOK Bracket System resists a lateral handrail load between 525 and 1400 lb/f.

  22. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In The DECKLOK Bracket System redirects the attachment load and places the resistance to the force in shear. This produces the strongest possible attachment for each of the deck connections.

  23. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In In addition to strength, the design of the DECKLOK Bracket allows for ductile failure which minimizes the potential of catastrophic failure of the rail post. Failed at 525 lbs

  24. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In DECKLOK Brackets are designed for integration with your project: * drill and bolt-on * handrail post location determines the bracket placement, not the other way around.

  25. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In The DECKLOK Bracket System allows for a uniform approach to the design and installation of the deck. Changes to home models and layout will not affect the use or the effectiveness of the DECKLOK Bracket.

  26. DECKLOK BRACKET SYSTEMSBuild In Safety - Lok It In The DECKLOK Bracket System ensures consistent quality across the board: * every state * every project * every house
