<br />FASTENING of FLOOR PANELS
<br />(1) Stagger nails when using 4" on-center spacing and maintain 3 8" joist and panel edge distance. One row of fasteners is permitted (two at abutting
<br />panel edges) for diaphragms. Fastener spacing for TJI® joists in diaphragm applications cannot be less than shown in table. When fastener spacing for
<br />blocking is less than spacing shown above, rectangular blocking must be used in lieu of TJI ® joists.
<br />(2) For non-diaphragm applications, multiple rows of fasteners are permitted if the rows are offset at least ½" and staggered.
<br />(3) With 10d (0.148" x 1½") nails, spacing can be reduced to 3" on-center for light gauge steel straps.
<br />(4) Can be reduced to 5" on-center if nail penetration into the narrow edge is no more than 1 14" (to minimize splitting).
<br />(5) Can be reduced to 4" on-center if nail penetration into the narrow edge is no more than 1 14" (to minimize splitting).
<br />(6) Can be reduced to 312" on-center if nail penetration into the narrow edge is no more than 1 14" (to minimize splitting).
<br />■ Recommended nailing is 12" on-center in field and 6" on-center along panel edge. Fastening requirements on engineered drawings supersede
<br />recommendations listed above.
<br />■ Maximum nail spacing for TJI® joists is 18" on-center.
<br />■ 14 ga. staples may be substituted for 8d (0.113" x 2 12") nails if minimum penetration of 1" into the TJI ® joist or rim board is achieved.
<br />■ To minimize splitting, maintain edge distance and row spacing of 21 2 x nail diameter or 3 8", whichever is greater.
<br />■ Nailing rows must be offset at least 12" and staggered.
<br />■ For recommended nailing and adhesives, see INSTALLATION RECOMMENDATIONS on page 2 of the Weyerhaeuser Installation Guide for Floor
<br />and Roof Framing, TJ-9001.

<br />FILLER and BACKER BLOCK SIZES
<br />(1) If necessary, increase filler and backer block height for face mount hangers and maintain 18" gap at top of joist; see detail W. Filler and backer block
<br />dimensions should accomodate required nailing without splitting (12" minimum for backer blocks and 24" minimum for filler blocks).
<br />(2) Clinch nails when possible.

<br />1. All blocking, hangers, rim boards and rim joists at the end supports of the TJI ® joists must be completely installed and properly nailed.
<br />2. Laterial strength, like braced end wall or an existing deck, must be established at the ends of the bay. This can also be
<br />accomplished by a temporary or permanent deck (sheathing) fastened to the first 4 feet of joists at the end of the bay.
<br />3. Safety bracing of 1x4 (minimum) must be nailed to a braced end wall or sheathed area (as in note 2) and to each joist.
<br />Without this bracing, buckling sideways or rollover is highly probable under light construction loads - such as a worker or
<br />one layer of unnailed sheathing.
<br />5. Ends of cantilevers require safety bracing on both the top and bottom flanges.
<br />6. The flanges must remain straight within 1/2" from true alignment.
<br />4. Sheathing must be completely attached to each TJI® joist before additional loads can be placed on the system.

<br />connections for side-loaded beams.
<br />When fasteners are required on both
<br />sides, stagger fasteners on the second
<br />side so they fall halfway between
<br />fasteners on the first side.
<br />(1) 10d nails are 0.128" diameter; 12d-16d nails are 0.148" - 0.162" diameter; screws are SDS, SDW, USP WS, or TrussLOK ®
<br />(2) An additional row of nails is required with depths of 14" or greater.
<br />(3) When connecting 4-ply members, nail each ply to the other and offset nail rows by 2" from the rows in the ply below.

<br />Fastener Installation Requirements
<br />Multiple-Member Connections for Top-Loaded Beams
<br />COLUMN DETAILS
<br />When joists are doubled at non-load bearing parallel
<br />partitions, space joists apart the width of the wall for
<br />plumbing or HVAC.
<br />Additional joist at plumbing drop (see detail).
<br />Subfloor adhesive will improve floor performance, but
<br />may not be required.
<br />Squash blocks and blocking panels carry stacked
<br />vertical loads (details B1 and B2). Packing out the web
<br />of a TJI® joist (with web stiffeners) is not a substitute
<br />for squash blocks or blocking panels.
<br />INSTALLATION TIPS
<br />Plumbing Drop
<br />Additional joist is required if
<br />floor panel edge is unsupported
<br />or if span rating is exceeded.
<br />Joist may be shifted up to 3" if
<br />floor panel edge is supported
<br />and span rating is not exceeded.
<br />Do not cut joist flanges.
