Observe the following guidelines:1.2.3.4.5.6.Properly install all blocking, hangers, rim boards, and rim joists at TJI joist end supports.E stablish a permanent deck (sheathing), fastened to the first 4 feet of joists at the end of the bay or braced end wall.Safety bracing of 1x4 (minimum) must be nailed to a braced end wall or sheathed area and to each joist.Sheathing must be completely attached to each TJI joist before additional loads can be placed on the system.Ends of cantilevers require safety bracing on both the top and bottom flanges.The flanges must remain straight within ½" from true alignment.This guide is intended for the products shown in dry-use conditions.La Sécurité Avant ToutLa Seguridad Ante TodoLire AttentivementPor Favor Lea CuidadosamenteAVERTISSEMENT Les solives non contreventées latéralement sont instables.

When latex subfloor adhesive is required, carefulselection is necessary due to a wide range of performancebetween brands. Nail panel to joist at 12" on-center in field and 6" on-centeralong panel edges. Apply fasteners 3 8" from panel edges. For ¾" panels, use 8d (0.131" x 2½") or 6d (0.120" x 2")deformed-shank nails or other code-approved fasteners.

Squash blocks and blocking panels carry stacked vertical loads(details B1 and B2). Packing out the web of a TJI joist (with webstiffeners) is not a substitute for squash blocks or blocking panels. When joists are doubled at non-load bearing parallel partitions,space joists apart the width of the wall for plumbing or HVAC. Additional joist at plumbing drop (see detail at right).Joist may be shifted upto 3" if floor panel edgeis supported and spanrating is not exceeded.Do not cut joist flanges.Additional joist isrequired if floor paneledge is unsupportedor if span rating isexceeded.

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) With 10d (0.148" x 1½") nails, spacing can be reduced to 3" on-center for light gauge steel straps.(4) Can be reduced to 5" on-center if nail penetration into the narrow edge is no more than 13 8" (to avoid splitting).(5) Can be reduced to 4" on-center if nail penetration into the narrow edge is no more than 13 8" (to avoid splitting). Recommended nailing is 12" on-center in field and 6" on-centeralong panel edge. Fastening requirements on engineered drawingssupersede recommendations listed above. For recommended nailing and adhesives, see INSTALLATIONRECOMMENDATIONS on page 2. Nailing rows must be offset at least ½" and staggered.1 4 ga. staples may be substituted for 8d (0.113" x 2½")nails if minimum penetration of 1" into the TJI joist orrim board is achieved.
