WARNING: JOISTS ARE UNSTABLE UNTIL BRACED LATERALLYBracing Includes: Blocking, Hangers, Rim Board, Sheathing, Rim Joist, Strut Lines

Lack of proper bracing during construction can result in serious accidents. Observe the following guidelines:

1. Properly install all blocking, hangers, rim boards, and rim joists at TJI® joist end supports.

2. Establish a permanent deck (sheathing), fastened to the first 4 feet of joists at the end of the bay or bracedend wall.

3. Safety bracing of 1x4 (minimum) must be nailed to a braced end wall or sheathed area and to each joist.

4. Sheathing must be completely attached to each TJI® joist before additional loads can be placed on the system.

5. Ends of cantilevers require safety bracing on both the top and bottom flanges.

6. The flanges must remain straight within 1 ⁄ 2" from true alignment.

Use support blocks at10' on-center to keep products

out of mud and water.

La Sécurité Avant Tout

AVERTISSEMENT Lire Attentivement

■ Les solives non contreventées latéralement sont instables. Voir le guided’installation avant la pose des solives TJI®.

■ Ne pas circuler sur les solives TJI® avant qu’elles ne soientadéquatement contreventées. Risque de blessure.

■ Ne pas empilées des matériaux sur des solives avant d’avoir installé les sous-plancher. Les entreposer temporairement au-dessus des poutres et murs.

La Seguridad Ante Todo

ADVERTENCIAPor Favor Lea Cuidadosamente

■ Las viguetas son inestables hasta que sean reforzadas lateralmente.Vea la guía de instalaciones antes de instalar las viguetas TJI®.

■ No camine sobre las viguetas hasta que sean apuntaladas.■ No ponga materiales de construcción sobre las viguetas TJI® antes de

instalar el triplay. Ponga materials únicamente sobre vigas o muros.

RECOMMENDED ADHESIVES

■ Adhesives must meet the requirements ofASTM D3498 (AFG-01), and they must have a

minimum dry shear strength of 350 psi. Formore information, contact your Weyerhaeuserrepresentative.

■ Increased bearing capacitiesmay be achieved with increasedbearing lengths. See plans for

DO NOT use sawn lumber for

TJI ® joist floor framing does not requirebridging or mid-span blocking

INSTALLATION TIPS

■ Subfloor adhesive will improve floor performance, but maynot be required.

■ Squash blocks and blocking panels carry stacked vertical

loads (details B1 and B2). Packing out the web of a TJI® joist(with web stiffeners) is not a substitute for squash blocks orblocking panels.

TJI® JOIST FLOOR FRAMING

■ When joists are doubled at non-load bearing parallel

partitions, space joists apart the width of the wall forplumbing or HVAC.

■ Additional joist at plumbing drop (see detail above).

WARNINGJoists are unstable until laterally braced.

See Warning on cover.

Safety bracing (1x4 minimum)at 8' on-center (6' on-centerfor TJI® 110 joists) andextended to a braced end wall.

Fasten at each joist with two 8d(0.113" x 21 ⁄ 2") nails minimum(see Warning on cover).

■ Recommended nailing is 12" on-center in field and 6" on-centeralong panel edge. Fastening requirements on engineered drawingssupersede recommendations listed above.

■ Weyerhaeuser recommends using a non-polyurethane subflooradhesive on all contact points between panels and floor framing.

■ Nailing rows must be offset at least 1 ⁄ 2" and staggered.

■ 14 ga. staples may be substituted for 8d(0.113" x 21 ⁄ 2") nails if minimum penetration of 1"into the TJI® joist or rim board is achieved.

■ Maximum spacing of nails is 18" on-center forTJI® joists.

Guidelines for Closest On-Center Spacing per Row

DETAIL SCHEDULE

Web stiffeners required on each side of joist at bearing. Refer to your Javelin® framing plan.

Bearing requirements as shown on the Javelin® framing plan are job-specific and supersede minimum bearing requirements listed.

JAVELIN® SOFTWARE FRAMING PLANS

(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 paneledges) for diaphragms. Fastener spacing for TJI® joists in diaphragm applications cannot be less than shown in table. When fastener spacing forblocking is less than spacing shown above, rectangular blocking must be used in lieu of TJI® joists.

(2) For non-diaphragm applications, multiple rows of fasteners are permitted if the rows are offset at least ½" and staggered.

(3) Can be reduced to 3" on-center for light gauge steel straps with 10d (0.148" x 1½") nails.

(4) Can be reduced to 4" on-center if nail penetration into the narrow edge is no more than 13 ⁄ 8" (to avoid splitting).

(3) Detail A3.3 shall be a segmented wall, location of full-height structural sheathing per code.

(4) Sheathing shall be continuous over all plate-to-plate and plate-to-rim-board interfaces and may butt together at mid-depth of rim board asshown in A3.4. At foundation, fasten the bottom edge of the sheathing to the sill plate.

(5) In addition, one 6'-8" standard door opening is allowed.

(6) If required, holdowns shall be Simpson Strong-Tie® CS20 (or equivalent) straps attached with four 8d (0.131" x 21 ⁄ 2") nails at each end. Asan alternative to holdown straps, wall sheathing may be attached as shown in A3.4. See footnote 4.

CONNECTOR INSTALLATION AND SQUEAK PREVENTION TIPS

■ Nails must be completely set.

■ Leave 1 ⁄ 16" clearance between the member and the supportmember or hanger.

■ Joist to beam connections require hangers; do not toenail.■ Seat the supported member tight to the bottom of the hanger.

On Simpson Strong-Tie® ITT, IUT, and VPA connectors, bend thebottom flange tabs over and nail to TJI® joist bottom flange.

■ Reduce squeaks by adding subfloor adhesive to the hangerseat.

Face mounthanger

APPROVED HANGERS

■ The following manufacturers are approved to supply hangersfor Trus Joist® products:

– Simpson Strong-Tie Co., Inc.: 1-800-999-5099 – USP Structural Connectors: 1-800-328-5934

■ Hanger design loads differ by support type and may exceed thecapacity of the support and/or supported member. Contact yourWeyerhaeuser representative or refer to Weyerhaeuser software.

NAILING REQUIREMENTS

■ Fill all round, dimple, and positive angle holes with the proper

nails. Hanger nails are usually a heavier gauge because of thehigher loads they need to carry.

■ Unless specified otherwise, full capacity of straps orconnectors can only be achieved if the following nailpenetration is provided:

FACE MOUNT TOP MOUNT

10d (0.148" x 11 ⁄ 2") 11 ⁄ 2" minimum 11 ⁄ 2" minimum

10d (0.148" x 3") 13 ⁄ 4" minimum 3" minimum

16d (0.162" x 31 ⁄ 2") 2" minimum 31 ⁄ 2" minimum

■ Top mount hangers should be fastened to TJI® joist headerswith 10d (0.148" x 11 ⁄ 2") nails. Fasten face mount hangersto 31 ⁄ 2" or wider TJI® joist headers with 10d (0.148" x 3") or16d (0.162" x 31 ⁄ 2") nails.

Minimum Bearing Length for Beams and Headers

DO NOT overhang seat cuts on beamsbeyond inside face of support member

Drive nails at an angle tominimize splitting of plate

Beam Attachment at Bearing

11 ⁄ 4" TimberStrand® LSL or11 ⁄ 8" TJ® rim board

■ Minimum bearing length: 11 ⁄ 2" at ends, 31 ⁄ 2" at intermediate supports.

■ Bearing across full beam width is required.

■ Bearing lengths shown are based on bearing stress for TimberStrand® LSL, Microllam® LVL, or Parallam® PSL. If the support member’s allowablebearing stress is lower (e.g., when bearing on a flat wood plate), lengthsmay need to be increased.

■ Table assumes maximum allowable uniform load. For other conditions,contact your Weyerhaeuser representative.

■ Beams and headers require lateral support at bearing points and along thetop (or compression edge) at 24" on-center or closer.

■ 13 ⁄ 4"-thick members that are 16" or deeper must be used in multiple-plyunits only.
